Introduction

While it’s impossible to do without finance, it has become too important and too powerful. Its complexity, whether apparent or real, makes it difficult for the layman to access. This is an unhealthy situation in a democracy. Because the sometimes very high incomes of traders and other players are well known. Because the power of finance is clearly as great as it is poorly controlled, as shown by the work on “regulator capture”. 1 . Let’s try to untangle this financial skein and see how we can put finance back at the service of citizens and the ecological transition.

The essentials

Finance carries out missions of general interest

Finance brings together all the institutions responsible for creating money and/or channelling savings (mainly from households and businesses) towards economic agents in need of financing.

These financial entities can be grouped into five main categories:

  • BANKS ;
  • insurance companies, some of which are bank-owned;
  • pension and retirement funds;
  • collective management organizations ;
  • and investment funds, some of which are speculative.

As the following diagram shows, each of these financial entities has different activities and functions.

By determining which players can access financing to bring their projects to fruition, and under what conditions, financial players play an essential role in the smooth running of the economy. Their activity is at the service of all other economic sectors and, in this respect, concerns the general interest. We would like to emphasize the following points:

Banks create money and analyze credit risks

Money is created by banks

Banks are special financial institutions: they play a specific and important role in the economy.

On the one hand, by managing deposits and means of payment, they are at the heart of the payment system, the major infrastructure of any market economy. The sudden closure of banks would paralyze the economy, as the vast majority of exchanges would no longer be able to take place in the absence of the tools needed to carry out the related financial transactions.

On the other hand, banks, mainly through their lending activity, create money and thus additional purchasing power, enabling projects to be carried out that would otherwise not have been possible(see the module on money). By deciding whether or not to grant credit, banks decide how and to whom the new purchasing power is directed, and which projects are or are not financed and can be carried out. In this, they have an important responsibility. If too much money is created, or allocated to the wrong projects, it can have harmful effects on society and the economy(see the module on money and Essentiel 4 below).

Risk analysis

Banks therefore also play an important role in analyzing credit quality. It’s a question of making a loan that’s well advised (i.e. that has a reasonable chance of being repaid by the borrower) without being overly cautious (which would also ruin the lender’s business, who needs to know how to take “reasoned” risks). Although the proverb says that you only lend to the rich, the reality is more nuanced, and we have to acknowledge that some banks have real expertise in this field: they are capable of analyzing a credit risk and proposing interest rate and collateral conditions adapted to the lender on the basis of this analysis.

The importance of serious credit analysis

The best proof of the social value of this activity was given a contrario by the ” subprime ” crisis. Loans granted without any serious analysis (the famous “ninja” loans: ” no income, no job, no asset “) had a negative impact on the economy. 2 ) were granted because they could be securitized, i.e. partially or totally removed from the balance sheet of the lenders and resold on the financial markets. This practice distanced the links between borrowers and final credit holders, diluting and spreading the credit risks associated with the entire financial system. The major crisis that ensued demonstrated the importance of serious credit analysis.

Financial players channel existing savings into new economic projects

In addition to bank money creation, financial players collect existing savings, i.e. the portion of income (mainly household income) that is not spent on current consumption, and use it to meet the financing needs of companies, households or public authorities.

In this respect, they play an important economic role, since they enable more (financial) resources to be used in the economy than would be the case if each saver were to invest directly: it is more difficult for an individual to identify and select projects or companies; financial players offer individuals the possibility of recovering, under certain conditions, the capital invested, thus reassuring savers.

Difference between primary and secondary markets :

The primary market is the “new market” on which an issuer (government, company) introduces financial securities (shares, debt securities) for the first time.

These securities can then be traded on the secondary market, a “second-hand market”. The value of the secondary market lies in the fact that it ensures the liquidity of financial securities, i.e. the possibility of converting them more or less rapidly into money. It thus facilitates the mobilization of capital to finance investments in the productive economy. Without this possibility, far fewer savers would consider allocating their financial assets to finance long-term projects that do not directly concern them.

The existence of secondary markets is not without perverse effects

The primary market is the only way to finance the productive economy. Savings channeled into the secondary market certainly ensure the liquidity of securities (and thus facilitate the issuance of these securities on the primary market), but it also has the effect of driving up their price (since they are in greater demand) and, if savings are in excess, creating destabilizing financial bubbles.

Moreover, the liquidity of financial securities at a given moment does not guarantee that this will always be the case. It gives the dangerous illusion of unconditional reversibility of financial decisions. In the event of a financial crisis, markets become illiquid: nobody wants to buy securities any more, everyone wants to sell, and prices plummet (see our fact sheet on liquidity ).

Finance helps manage risk

The development of financial techniques goes back a long way. European merchants would doubtless have been less adventurous in the Middle Ages had it not been for the inventiveness of financiers offering them insurance or “paper” instruments (such as promissory bills) that would have saved them the trouble of carrying gold coins. 3 .

The mission of finance and insurance is to manage the risks associated with economic activity. These are difficult professions, requiring experience and methods that can legitimately be sophisticated (because the activities of the real economy can be complex). It would therefore be counter-productive to deny all interest in financial innovation and to prohibit all new financial products on principle.

More precisely, finance manages risk from a specific perspective: the trade-off between return and risk. The idea is simple: every economic player takes a risk with every transaction (see box). When they don’t bear the risk directly (particularly in the credit business), financial players offer services that either delegate the management of this risk-taking, or hedge it partially or totally (via derivatives ). In exchange, they expect a return (which may take the form of an interest rate, dividends, etc.). The higher the risk, the higher the expected return.

Examples of risks taken by various economic players

– A lending banker takes the risk of not being repaid, or being repaid late.

– A company exporting a good takes on at least two risks vis-à-vis its customer: the risk of not being paid, and the risk of being paid in a currency that has lost value. If the currency is not automatically convertible, it also takes on the risk of inconvertibility (see the module on currency).

– A household that invests its savings takes the risk that they will lose value (through inflation or because the chosen investments have lost their value).

If there aren’t many truths in the financial world, there’s one we can remember: it’s an illusion to believe that you can earn money over the long term by investing it risk-free. The financiers in charge of investing household money, insurers, asset managers and pension funds all know this, and use a formula which, in this case, has a precise and very accurate meaning: ” there is no free lunch “. 4 . This is the idea that there is no such thing as a financial strategy that, for zero initial cost, will enable you to acquire definite wealth. Even more technically, there are no arbitrage opportunities on the financial markets. Financial advisors who offer “martingales”, who promise “magic” returns, are swindlers or liars (at least by omission). They deliberately or inadvertently forget to mention the risk they are passing on to those who follow their advice. This idea is sometimes confused with that of market efficiency, which is, on the contrary, a dogma without any foundation or precise definition (see Misconception 1).

The banking and financial sphere has grown by leaps and bounds in recent decades.

In the vocabulary of finance, financialization refers to the increased reliance of all economic agents on external financing, and in particular debt, compared with previous periods. Over the past 50 years, the world economy has clearly become increasingly financialized, with finance playing a growing role in the global economy. This financialization is the result of economic and political evolutions that have affected most advanced economies since the 1970s (see Essentiel 3).

Numerous indicators show the growth of the financial sphere relative to the productive economy:

  • the growth in the relative weight of the banking and financial sector in GDP, the growth in the income of individuals working in the financial sector and their growing share of the highest incomes;
  • the relative weight of goods that are the subject of a financial market (oil, gas, coal, metals, foodstuffs such as wheat, soya, etc.);
  • growth in the volume of “derivatives”;
  • the growing dependence of governments on financial markets for their financing.
  • the weight of finance in corporate shareholding (compared with that of individuals and non-financial companies) – see Essentiel 5.

Disconnecting the financial sphere from the productive economy

According to the Financial Stability Board (FSB) 5 global financial assets have risen from around $128,000 billion in 2002, or 370% of GDP, to over 400,000 billion euros in 2019, or 460% of GDP. As can be seen from the following graph, the crisis of 2007-2008 only slightly slowed the continued growth of the financial sphere.

Total financial assets 2002-2019

As economists Gunther Capelle-Blancard and Jézabel Couppey Soubeyran point out in the article Une régulation à la traîne de la finance globale (2018), the lack of strict proportionality between flows in the financial sphere and those in the productive sphere is not surprising in itself. For example, it’s understandable that in order to finance international trade activities and hedge the associated risks (currency and interest-rate risk in particular), several flows are required on the foreign exchange and derivatives markets 6 . “However, when 70 times the value of international trade is exchanged on the foreign exchange market in a single year, there is every reason to believe that the financial sector is no longer serving the real economy, and is now primarily serving itself.

The excesses of finance

In the same article, the authors highlight “some measures of excess” in finance:

“There are many measures that can be used to account for the explosion of finance. In the OECD countries, credit to the private sector rose from an average of around 50% of GDP in the 1970s to over 100% of GDP at the time of the financial crisis, and has remained at this level ever since. 7 . Bank balance sheets grew at an exponential rate at the turn of the 1990s-2000s, particularly in Europe, where they now represent the equivalent of 3.5 times GDP, compared with 1.8 times in Japan and 1.2 times in the U.S. 8 . The financial crisis of 2007-2008 slowed this trend, but did not reverse it. Globally, assets managed by banks practically tripled during the 2000s, rising from just over $50,000 billion at the end of 2003 to $133,000 billion at the end of 2015 [ed. note: $155,000 billion in 2019]. 9 .

Transaction volumes on the stock, foreign exchange and derivatives markets also illustrate this disproportionate growth. These financial quantities are now out of all proportion to those of the real world. Remember that in 2008, merchandise trade between the G7 countries was worth $3,000 billion (before declining with the crisis), and global GDP was worth $75,500 billion in 2016. And yet, despite the crisis and the slowdown it may have brought about, financial transactions amount to hundreds of thousands of billions of dollars. The Bank for International Settlements (BIS) estimated the notional amount of derivatives outstanding at $483,000 billion at the end of December 2016 [ndr $558,500 billion in 2019].

As far as the foreign exchange market is concerned, the BIS triennial survey published in 2016 suggested a slight contraction, but still estimated the daily volume of foreign exchange transactions at over 5,000 billion (equivalent to more than 2.5 times the GDP of a country like France in a single day) [ndr $6600 billion at the end of 2019].

And last but not least, equity market transactions today amount to more than $100,000 billion every year, equivalent to almost 150% of global GDP, compared with just 5% in 1975. 10 . This increase is essentially driven by the boom inhigh-frequency trading (HFT), which now accounts for between half and two-thirds of trading volumes, with transactions carried out at microsecond intervals.”

Financialization took off in the 1970s as a result of neo-liberal political decisions.

The decades following the Second World War were marked by strict regulation of the financial sector, sometimes referred to as “financial repression”. 11 A fixed, controlled exchange rate based on the convertibility of the dollar into gold 12 set up following the Bretton Woods agreements; control of transnational capital movements; supervision of credit activities; segmentation of the banking and financial industry. States financed themselves by mobilizing domestic savings, obtaining preferential loans from captive national publics (such as pension funds or national banks) or from their central bank.

Generally speaking, central banks were in a position of relative subordination to governments: monetary policy was used in conjunction with fiscal policy to pursue economic policies aimed at sustaining activity, or curbing it in periods of overheating. It was also at this time that the welfare state, a system of mutualized social insurance at national level, developed in many countries.

This period of strong state intervention in the economy gradually came to an end in the 1970s. Against a backdrop of greater instability, marked in particular by the end of the Bretton Woods exchange rate system, oil shocks and the emergence of stagflation (concomitant inflation and mass unemployment), neoliberal theses, which had hitherto gone unheeded, gained ground in political circles on both the right and left in advanced countries. The aim is to promote the market economy and the “open society” on a global scale, and to limit public intervention in the economy to ensuring social stability and the smooth functioning of markets.

In financial terms, this is reflected in a vast movement towards liberalization and globalization, sometimes referred to as the 3D movement. 13 movement” (deregulation, decompartmentalization, disintermediation). Without claiming to be exhaustive, let’s highlight just a few of the major developments in this movement.

The end of the Bretton Woods Agreement and the introduction of a floating exchange rate system

In August 1971, faced with the melting of the country’s gold reserves, US President Nixon decided to suspend the convertibility of the dollar. The new system of floating exchange rates was ratified by the Jamaica Agreements in 1976. Henceforth, the price of currencies on the foreign exchange market would evolve according to supply and demand. This opened the door to currency speculation. Currency crises multiply around the world 14 with major consequences for the economies concerned, given the importance of the exchange rate on the price of exports and imports. (See Essentials 11 and 12 in the currency module). Moreover, the introduction of floating exchange rates, by creating a new risk (currency risk) in international trade, will provide the impetus for the growth of derivatives.

Free movement of capital

The end of the Bretton Woods system was accompanied by the gradual lifting of controls on transnational capital movements. From the 1980s onwards, advanced countries, led by the United States, gradually opened up their public debt markets to foreign investors. Financial players were then given the opportunity not only to invest wherever they wished on the planet, but also to set up in other countries to compete with local financial players. These policies were also promoted and even imposed on developing countries following the adoption of the Washington Consensus doctrine by the IMF and the World Bank. 15 . The opening of borders to capital movements has several negative consequences for the global economy: it contributes to the emergence of mega-banks, encourages the development of international speculative movements that destabilize national economies, and facilitates tax evasion and money laundering in tax havens.

The deregulation of lending activities and the development of prudential regulation of banks

From the 1970s onwards, most advanced economies deregulated the credit sector, gradually removing some of the limits on banks. All rules aimed at directly limiting (via quotas, for example) the quantity of credit granted by banks, as well as the orientation of credit according to economic sectors, came to an end. This period also saw the end of bank specialization by type of activity (retail banking, investment banking, banks specializing in local credit, etc.), or by geographical area (in the United States, for example, banks were not allowed to expand beyond a single state). Many governments allow banks to engage in non-banking activities, such as insurance or asset management. Some countries are also lifting constraints on borrowers.

These different trends are reflected in the concentration of the sector, leading to the emergence of international mega-banks, some of which are “universal” in the sense that they are active in all areas of finance.

At the same time, following the resurgence of banking crises virtually unheard of in the previous period, prudential regulation of banks developed with the establishment of the Basel Committee. Banks were required to hold a minimum level of capital to guarantee their ability to absorb losses arising from borrower defaults. However, these rules have not prevented a proliferation of banking crises, nor the outbreak of the systemic crisis of 2008 (see our fact sheet on prudential regulation). On the contrary, they had the perverse effect of leading some banks to securitize loans so as not to keep them on their balance sheet, thereby reducing their incentives to analyze credit risk properly. This perverse mechanism was at the heart of the 2008 crisis.

Disarming public authorities

This period of financial liberalization was also marked by the placing of public debt on the market. The various mechanisms that had previously enabled public deficits to be financed at low cost were abolished. Expensive governments had to submit to the “healthy” discipline of the market(see the module on money). The “debt order” is gradually established. 16 as intense bond-issuing activity developed, generating fees for banks and “safe” assets (government bonds) for financial investors.

Lastly, this period coincided with an evolution in doctrine concerning the governance and missions of central banks, as well as the role of monetary policy. On the one hand, the role of central banks was now confined to monetary stability (the fight against inflation). It wasn’t until their decisive intervention during the 2008 crisis that the objective of financial stability returned to the heart of their missions. On the other hand, the model of independent central banks became widespread, on the grounds that governments’ inflation targets were insufficiently credible, as they were marked by time inconsistencies (linked in particular to their desire to win re-election).

Financial activity is at the root of cycles and crises that are harmful to society and the environment.

Hyman Minsky clearly demonstrated the intrinsic instability of liberalized finance. 17 . After a period of growth, investors begin to take greater and greater risks, while lenders become less and less cautious. This triggers a phase in which rising asset prices and rapid credit expansion reinforce each other, jeopardizing the stability of the system (see below). The point at which over-indebted investors are forced to sell their assets en masse to meet their debts is sometimes referred to as the “Minsky moment”, triggering a self-sustaining downward spiral in asset prices and a drying-up of liquidity. Far from impacting only the financial sector, financial crises can be transmitted to the economy as a whole, particularly through overindebtedness and the drying-up of credit.

This has dramatic social consequences, with rising poverty, unemployment and inequality. They also result in a further delay in addressing the ecological emergency, as decisions in favor of transition are postponed or watered down. How can we raise taxes on energy when precariousness is on the rise and public money is lacking to compensate for its effects? How, in such a context, can economic players (local authorities, businesses and households) decide on long-term investments?

Private debt is at the heart of this financial instability

The following graphs show how debt (public and private) has risen inexorably since the 1970s. Worldwide, it rose from 114% to 227% of GDP in 2018.

Global debt as % of GDP (1970-2018)

This trend is even stronger in the so-called advanced countries 18 total debt reached 267% of GDP in 2018, compared with 125% in 1970.

While debate focuses on public debt, private debt (that of households and non-financial companies) is far more significant. In the years leading up to the 2007-2008 financial crisis, both globally and in the advanced economies, private debt was more than double public debt. The gap has since narrowed, not least because governments have assumed a large share of the consequences of the crisis, whether by supporting the financial sector or bearing the social costs.

The importance of private debt is of great concern, as the root cause of both the Great Depression of the 1930s and the crisis of 2007-2008 was the bursting of a debt-financed speculative bubble. Rising debt and speculative bubbles go hand in hand. One of the main reasons for this is that loans are granted with “collateral” that is in fact speculative (real estate or financial securities). The supply of and demand for debt are both increasing functions of expectations of rising asset prices. In this mechanism, there is no restoring force. Credit providers feel protected by the rising financial value of collateral (speculative asset). Credit seekers, always on the lookout for added value, increase their demand for debt as speculative bubbles develop.

A strong correlation between the banking crisis and financial liberalization

From a factual point of view, there is a strong correlation between the number of banking and financial crises and periods of financial liberalization, as shown in the following graph:

Proportion of countries having experienced a banking crisis (weighted by each country’s weight in world GDP) over the period 1900-2008

This graph illustrates the incidence of banking crises among the sample of 66 countries (representing around 90% of global GDP) used in Carmen Reinhart and Kenneth Rogoff’s study. Each country is weighted according to its share of global GDP, to provide a measure of the “global” impact of local banking crises. We can see that there were virtually no crises in the period following the Second World War, and that they increased significantly from the late 1970s onwards.

Financialization has many negative consequences for the economy

As we saw in Essentiel 4, the intrinsically unstable nature of finance is a source of crises that reverberate throughout the economy, with dramatic social consequences. On the ecological front, financial and economic crises have most often resulted in a delay in the necessary transition to a low-carbon economy. At a time of mass unemployment and massive indebtedness, the investments needed for the transition and environmental regulations are being postponed (or even scaled back in the case of regulations) on the grounds that priority should be given to employment, recovery and growth.

As we shall see, beyond this periodic destabilization of the economy, financialization also has other negative impacts.

Companies’ shorter time horizons

The financialization of the economy has been accompanied by the widespread adoption of a management model for listed companies aimed atmaximizing shareholder value. According to this doctrine, the interests of shareholders, seen as the owners of the company, take precedence over those of all other stakeholders (employees, suppliers, customers, etc.). Executives and managers, whose interests are aligned with those of shareholders via various mechanisms (bonuses, stock options), must first and foremost pursue the objective of maximizing return on equity (ROE). To achieve this, they adopt a variety of practices aimed at increasing dividend payouts and boosting share prices: focusing on cost reduction, limiting investment (tangible or intangible _R&D), increasing debt leverage, share buy-backs.

This form of corporate governance diverts profit from productive investment, while increasing the company’s financial fragility through growing indebtedness. It also leads to a decline in the share of wages in value added, due to the focus on cost reduction and the weakening of employees’ collective bargaining power. According to the OECD, over the period from 1990 to 2009, the share of labor compensation in national income fell in 26 of the 30 advanced countries for which data were available 19 . The median labor share of national income in all these countries fell considerably, from 66.1% to 61.7%.

Changes in the balance of power within the company

In order to reduce labor costs, a movement to externalize many corporate management functions was initiated in the 1980s-90s, encouraged by new information and communications technologies. This led to a radical change in the structure of large corporations: they moved from a pyramidal structure to one based on networks, where one coordination center can direct a multiplicity of profit centers spread around the world in real time. This development has considerably strengthened the power of corporate management elites (particularly financial managers), annihilating internal checks and balances, but also modifying the balance of power with governments, insofar as this type of group structuring enables multinational firms to implement particularly effective tax optimization, avoidance and evasion strategies.

Thus, the financialization of corporate management, with the shift in the 80s to a mode of governance based on maximizing shareholder value coupled with the rise of financial institutions 20 focused on generating short-term profits for shareholders, managers generally neglect measures and investments aimed at the company’s long-term profitability and even viability.

Needless to say, this also applies to ecological and climate transition strategies, which require projections into the future and substantial investments to decarbonize or even reorient the company’s activities. This short-termist logic is not limited to listed companies: because of the market power of multinationals, it spreads to the rest of the economy via the chain of suppliers and subcontractors.

Finally, it should be noted that this model of the financialized company is also partly responsible for the increase in private debt. Companies take on debt to support their shareholders’ financial returns, or to buy back their own shares, even if this means jeopardizing their very survival; households take on debt to support their consumption in a context of stagnating purchasing power, partly created by the dogma of shareholder value; the financial sector itself and speculators take on debt to take advantage of the speculative opportunities offered by a hypertrophied, globalized financial system.

Rising income inequality

The increase in income inequality over recent decades is well documented. A number of factors have contributed to this: less progressive tax policies, globalization which has exerted downward pressure on incomes in advanced countries (due to competition from low-wage countries), the pursuit of automation and the start of robotization… Financialization has played its part through various channels:

-Income from financial activities is on average higher than in other sectors, sometimes reaching astronomical levels, as in the case of traders. This point no longer needs to be made, as studies on the subject abound. 21 .

-Another source of financial inequality is unequal access to credit and financial services: high-income earners have easy access to credit, enabling them to take advantage of the investment opportunities they spot; financial and real-estate bubbles contribute, for as long as they last, to increasing income from wealth (rents, dividends, capital gains on asset disposals, interest income); wealthier households have the means to call in experts to “optimize” their taxes, or even to evade the taxman, which in turn reduces revenue and therefore the redistributive capacity of governments. At the other end of the income distribution scale, debt can be a factor in poverty traps. Unlike high-income households, poor households do not take out credit in order to exploit investment opportunities and thus enrich themselves. These households have seen their incomes stagnate or fall, notably due to the advent of shareholder value as a corporate management principle (see previous point) and the rise in housing costs (a consequence of real estate bubbles). Credit to these households enables producers to sell their products. In the short term, it enables households to “cope”, but in the long term, the burden of interest penalizes them even more.

-Finally, financialization is increasing poverty and inequality, due to the impact of financial crises on the economy (with rising unemployment and, more generally, underemployment) and on public finances. Household income inequality in OECD countries (before taxes and transfers) measured by the GINI index rose by 1.4% over the 2007-2010 period. 22 . The actions taken by governments to rescue the financial system and the consequences of the crisis on public finances (lower tax revenues, higher social spending) have resulted in a considerable increase in public debt. In fiscally constrained countries such as those of the European Union, the level of debt very quickly justified the implementation of austerity policies with disastrous social consequences, such as a reduction in the quality of public services (or even the disengagement of the State), primarily affecting the most disadvantaged populations. It should be noted that this austerity has proved counterproductive in terms of its primary objective: debt reduction (see our fact sheet on the budget multiplier ).

The detour of financial activity from the real economy

As noted in Essentials 1, the banking and financial sector is expected to provide services to all other sectors of the economy. Economics textbooks generally describe banks as lending to support activity and finance new investment.

However, the financialization of the economy is changing all this. Adair Turner, former head of the UK’s Financial Supervision Authority, points out that in today’s banking systems, most loans do not finance real new investments, but the purchase of existing assets, whether real estate or financial securities (on the “secondary market”, see Essentiel 1). 23 . Credit excesses do not therefore reflect over-financing of productive activity, but rather fuel bubbles.

Credit can also fuel over-investment in certain sectors. In the heart of Europe, Ireland and Spain suffered cruelly from such over-investment in real estate in the pre-crisis period, leaving the countries bereft, socially damaged by the bankruptcies of builders and developers and the resulting unemployment, banks gorged with bad debts, and a territory blighted by ghost-buildings that can’t find buyers and have often been halted before completion.

Bad loans are therefore those that do not finance useful investments. Adair Turner points out that in Great Britain, in 2012, of the 1,600 billion in outstanding bank loans to non-financial players, only 14% went towards productive business investment. The rest went to office property (14%), residential property (65%) and household consumption (7%). This is the general trend in advanced economies (see the Money module).

Savings are also massively channelled into the purchase of existing assets on secondary markets. In so doing, they contribute to the liquidity of securities and thus to the success of primary market issues, but do not provide new financing for the real economy. This is all the more true when savings or credit are used to speculate on derivatives. Finally, as we saw above, the financialization of the economy has been accompanied by the spread of the shareholder value management standard, which subjects companies to an arbitrary standard of financial return to satisfy shareholders, sometimes to the detriment of their long-term viability.

Volatile financial markets prevent the “price signal” from reflecting changes in the scarcity of raw materials

For a number of products, “derivatives” have been progressively invented which “complete” the market, thus contributing, from the doxa’s point of view, to improving the functioning of said market. It is possible to buy a barrel of oil futures, a call (or put) option on that barrel, and then a host of “derivatives”, the imagination being limitless in this area.

Contrary to the initial idea of stabilization, price volatility on these financialized markets has, on average, increased. The risks of banking, monetary and financial crises have increased. This is clearly not in the interests of manufacturers and farmers, who are seeking to protect themselves from this volatility.

As a result, the price signal observed on these markets has become blurred and, contrary to popular belief, no longer provides information on quantities. Take oil, for example. Its price peaked in 2008 at $140, only to fall back to less than $60 a few months later. Clearly, during this period, neither proven oil reserves nor global production capacity changed substantially. The price per barrel therefore provides no information on the physical realities of the market. It does, however, provide information on the instantaneous mood of the markets?

That’s why mathematician Nicolas Bouleau describes markets as “smoke and mirrors “. As he shows, it is also possible that, for purely mathematical reasons, the price of a raw material could collapse even though its resources are close to exhaustion.

So, if we want to guard against the risk of exhaustion, it’s up to public authorities to build up and communicate quality information on the physical realities of strategic markets.

Rising commodity price volatility and large-scale social crises in developing countries

As early as the end of the 19th century, specialized markets (mostly located in London and Chicago) were established. Cereals, rice, soybeans, cocoa, copper, nickel, rare earths and precious metals… are traded on financial markets where financial and non-financial players negotiate not only physical products (the underlyings), but increasingly contracts and ” derivatives “. While some players might have hoped for price control, or at least a degree of stability and reduced volatility, the opposite is true. The consequences are unfortunately very real, and harmful to the most disadvantaged. Take, for example, the “bread riots” in Egypt, following the doubling of wheat prices between April 2007 and April 2008, from 5 to 10 dollars a bushel, a doubling that was not justified by any shortage. At the same time, we witnessed a 20-fold increase in futures contracts held between 2003 and 2008, from $13 billion to $260. While this is not absolute proof of causality (of the effect of financialization on price rises, or at least of their greater volatility), it is, on the contrary, clear evidence of the absence of a stabilizing effect.

As Ivar Ekeland and Jean-Charles Rochet note in their book, the U.S. Congress tried, unsuccessfully, to remedy this situation in 2010 24 .

“The Dodd-Franck Act calls on the Commodities futures Trading Commission (CFTC) to impose limits on speculative positions in commodities (also including metals oil and gas) when it deems speculation in these markets “excessive”. The rule was adopted on October 18, 2011, despite intensive lobbying by the financial industry. It was immediately attacked by two trade associations (ISDA and SIFMA), who argued that the CFTC had failed to conduct a prior cost-benefit analysis showing that its new rule would be beneficial. On September 28, 2012, a federal judge sided with the financial industry and struck down the new rule adopted by the CFTC on the grounds that it had presented no quantitative or empirical analysis showing that the new regulation would benefit the market! 25 Triumph of finance: the judge no longer takes the citizen’s point of view, but the market’s!”

The risk of a new systemic financial crisis still exists

In the aftermath of the 2008 crisis, the firmness of public statements 26 made it possible to envisage a real return to financial control. A decade later, after intense negotiations with the banking industry in all the world’s major countries, measures have certainly been adopted to reduce the risks taken by financial players. But, as the many studies published to mark the tenth anniversary of the crisis underline 27 these measures are far from sufficient to protect the economy from another banking and financial crisis.

“This time it’s different

On September 21, 2015, Mark Carney, Governor of the Bank of England denounced in a remarkable speech 28 three widely held preconceptions about finance. “This time it’s different 29 is the first of these preconceptions.

This expression refers to the conviction, repeated over and over again in history, that this time the economy will escape a financial crisis. It refers to this collective blindness and the certainty that this time the financial euphoria has a sound basis. The good health of finance is merely a mirror image of the good performance of the real economy.

In the name of this conviction, in the years leading up to the 2008 crisis, we believed that controlling inflation was the guarantee of financial stability, and we allowed private debt to grow indiscriminately. Financial innovations such as securitization, structured finance products and derivatives both boosted and stimulated the destabilizing drift of credit. As Adair Turner points out: “In the pre-crisis years, economic orthodoxy was characterized by anathema to government money creation and a totally relaxed attitude to the level of private debt created by the markets. The latter led to a disaster from which many ordinary citizens around the world are still suffering.” 30

The 2008 financial crisis put systemic risk back at the center of public authorities’ attention.

This expression refers to the fact that a particular event causes a chain reaction of negative effects on the entire financial system, culminating in its collapse. It is all the more serious because the impact is not limited to the financial sphere, but spreads to the rest of the economy.

The 2008 crisis highlights the two dimensions of systemic risk.

The transversal dimension is linked to the interdependence between financial institutions. Not all economic sectors are subject to the risk of contagion: for example, if a major car manufacturer like Renault goes bankrupt, there’s no reason why its competitor Peugeot should, quite the contrary. The situation is different for banks (and financial players in general). They are unique in that they lend to each other on a massive scale. As a result, the failure of a very large bank can have a knock-on effect on other financial institutions, since the latter will have to bear losses on assets that were not considered risky in the first place (and for which they had therefore not set aside sufficient capital). This is how the real estate crisis in the United States, triggered by subprime defaults, which could have remained local, was transmitted to the entire global financial system via the collapse of a very large bank, Lehman Brothers.

The temporal dimension is linked to the procyclical nature of players’ behavior: as the financial cycle rises, risk increases as agents take on debt and invest, following a bubble-forming logic in which rising asset prices and debt are self-perpetuating (see l’Essentiel 4 and our fact sheet on Minsky and Fisher ); conversely, in the downturn of the financial cycle, rational behavior at the microeconomic level (stopping lending to other potentially insolvent players, selling supposedly risky assets or to free up financial resources or before prices fall too far) deepens the crisis at the global level (collapse of asset prices, liquidity crisis).

Despite public regulation, the face of the global financial system has not fundamentally changed

Without going into the details of post-crisis financial regulations, we will simply highlight a few figures which show that the financial sector does not seem to have turned any significant corner.

The financial system has continued to grow and still represents around 500% of GDP. It remains as concentrated and interconnected as ever (see Essentiel 8). The shadow banking “remains as important as ever, and is no longer regulated. There are still 30 systemic banks, and even if they are better capitalized than before the financial crisis, this does not guarantee that they could cope with a new global crisis without help from the public authorities.

In short, systemic risk is present in its cross-functional dimension.

As for the time dimension, you only have to look at the levels reached by the equity and real estate markets to realize the financial euphoria underway.

Stock market valuations are reaching record levels, as shown by the following chart tracing the long history of the Dow Jones index (see also here for the S&P500, here for the Nasdaq, here for the Stock Europe 600).

In many countries, real estate has caught up with or even exceeded its 2007 level. This is the case, for example, in the United States, France, the United Kingdom and Germany.

It is impossible to predict when a crisis will erupt, or how deep it will go, how long it will last, or what its economic consequences will be. All we can say is that the financial system is still a long way from a state where any risk of crisis is eliminated or becomes highly unlikely.

However, there is a fundamental difference between the current period and the pre-2008 period: banks and financial markets are on a drip-feed of liquidity from central banks. The financial system is kept weightless, and continues to boom despite the economic crisis linked to the measures taken to deal with the COVID 19 pandemic. It is no longer just the indebtedness of private players (households and companies) and financial players that is fuelling the bubbles, but the monetary policy pursued by central banks.

One final point: the COVID-19 crisis has highlighted a new reality at the start of the 21st century: the sources of destabilization in the financial system can come from our natural environment. This realization is not entirely new: back in 2015, the systemic risks posed by climate disruption to financial activity were identified by Mark Carney in his now-famous “tragedy of the horizons” speech(see next point).

Climate is a source of proven systemic risks

In September 2015, in a speech delivered at Lloyd’s headquarters, Mark Carney, Governor of the Bank of England and Chairman of the Financial Stability Board 5 stated that global warming poses risks with potentially systemic financial consequences.

He introduces the concept of the “tragedy of horizons”. The gap between the short-term horizons of financial players and the long-term horizons of climate impacts means that financial players are unable to identify the risks they run as a result of global warming. It also draws up a typology of these risks.

Following this seminal speech, central banks around the world took up the subject. As a result, the Network of Central Banks and Supervisors for the Greening of Finance was created at the end of 2017. It aims to develop and promote methodologies to better identify and measure the financial sector’s exposure to climate risk, to draw up climate stress tests, but also to promote financing for the transition to a low-carbon economy. To date, however, supervisors’ attention has focused much more on risk measurement than on adapting monetary and prudential policies to combat global warming(see the module on money).

Physical risks: insurance and investor exposure to the physical consequences of global warming

Global warming generates “extreme” meteorological events (cyclones, heatwaves, intense rainfall events, etc.), i.e. those that statistically significantly exceed historically observed reference levels. It also manifests itself in profound changes to the natural environment, such as rising sea levels or the melting of continental glaciers (which feed the planet’s major rivers). Physical risks concern the destruction of asset stocks (due to forest fires, floods, cyclones, rising oceans, etc.), the reduced profitability of exposed companies and/or the deterioration of income streams (impact on tourism, fishing, harvests or the incomes of workers in the areas concerned, disruption of production chains, etc.). This physical damage can directly affect the longevity of capital and accelerate its depreciation. The direct impact on financial stability comes via the often cumulative and highly correlated losses of insurers and reinsurers, but also via other transmission belts that are sometimes just as direct, such as lending channels or bank investments. These physical risks will generate feedback and contagion effects between sectors and regions that are very difficult to quantify.

Transition risks: the economic and financial consequences of reducing greenhouse gas emissions

Reductions in greenhouse gas (GHG) emissions can result from the implementation or mere announcement of low-carbon policies (carbon tax, banning certain polluting vehicles from city centers, ambitious trajectory to increase the share of renewable energies in the energy mix, etc.), from a technological breakthrough making a rapid transition possible, or from a shift in individual preferences and social norms. In all cases, economic activities are affected more or less strongly and rapidly. In financial terms, the most feared transition risk is that of a sudden adjustment in asset prices.

The polarization of market expectations in response to such changes in climate policy, technology or behavior can lead to a sharp depreciation of assets backed by high-carbon activities (e.g. fossil fuel exploitation), with chain effects that are difficult to assess. These assets are known as stranded assets, in the sense that they are backed by investments that have lost all or part of their value before the end of their economic life, due to unforeseen regulatory or technological developments.

The difficult trade-off between physical risk and transition risk

Rapid decarbonization of the economy means short-term materialization of the transition risk, but long-term mitigation of the physical risk. If a rapid low-carbon transition in line with the Paris Agreement commitments were to be implemented, a large proportion of existing infrastructure, industrial plants and machinery would have to be scrapped or entirely converted. Fossil fuel extraction and transportation infrastructures would be the first to be affected, but many industrial facilities upstream and downstream of fossil fuel combustion would also be heavily impacted. Companies owning or operating these assets or infrastructures would be severely penalized economically, as would their bankers and investors.

The following table is taken from an article published in 2019 31 in which the authors carried out a systemic empirical analysis for a number of European countries of the stocks of productive capital exposed to the risk of stranding, in particular via cascade effects due to sectoral interdependencies. As can be seen, losses can represent very substantial portions of the sectors analyzed.

Analysis of productive capital stocks

The link between public climate policies and the direct realization of transition risk considerably complicates public decision-making. Indeed, a public climate policy leading to a massive and widespread depreciation of carbon assets would manifest itself in the short term as a systemic financial crisis, whereas the effects on the climate would only be felt over several decades. 32 . This is one of the manifestations of the tragedy of horizons.

This is also a challenge for central banks. In the event of a climate-related financial crisis affecting the solvency of banks and insurance companies, central banks will be under massive pressure to buy assets impaired by physical and transitional risks. They will then be, against their will, climate loss absorbers of last resort rather than mere lenders of last resort.

Liability risks

These risks concern legal action taken by victims of natural disasters attributable to climate change to seek compensation from those they hold responsible. Such proceedings can hit carbon-based industries and their insurers hard. These lawsuits can damage the reputation and solvency of the companies concerned, and even bankrupt them (see box).

The bankruptcy of Pacific Gas & Electric

Following devastating fires in California, Pacific Gas & Electric was indicted for negligence. Estimating that it would have to pay nearly 30 billion in damages, the company, unable to meet its obligations, filed for Chapter 11 protection, which temporarily protects it from its creditors. Stock market collapse, losses for holders of bonds issued by the company and for their insurers: the mechanisms for transforming legal risk into financial risk are fairly straightforward, although difficult to quantify.

The banking and financial system is too concentrated

The free movement of capital and the decompartmentalization of banking and financial activities have led to financial globalization: financial activities and players have taken on a cross-border or even international dimension, giving rise to financial multinationals with dominant positions in virtually every segment of the banking and financial services market.

This is particularly evident in the banking sector. Since 2011, the Financial Stability Board 5 has maintained a list of so-called systemic banks, known as G-SIBs (Global Systemically Important Banks). Since 2016, there have been 30 of these banks, whose failure would be likely to cause a contagious collapse of the international financial system as a whole. According to the Global Capital Index of the Federal Deposit Insurance Corporation (one of the US regulatory bodies), these 30 systemic banking groups weighed in at over $53,000 billion at the end of 2017 (aggregate balance sheet size), or almost 53% of global banking assets (which , according to the Financial Stability Board, totalled over $141,000 billion in 2017).

According to François Morin , four of these groups (Deutsche Bank, Citigroup, Barclays, UBS) accounted for 50% of foreign exchange market transactions in 2015 (with ten accounting for 80%). Fourteen of them belonged to the eighteen groups making up the Libor (London Interbank Offered Rate) panel, putting them in a position to influence the main market benchmark for determining the price of money in the very short term. These groups are also dominant on the public debt market, acting as intermediaries between issuing governments and investors purchasing public securities.

This concentration is not immutable: it is the fruit of history, as can be seen by looking at the evolution of the concentration of banking assets in the United States over a long period, as a function of group size.

Concentration of banking assets

As Jézabel Couppey Soubeyran and Gunther Capelle-Blancard note, “The size of institutions and the market concentration that goes with it result, at least in part, from a logic that is very specific to the banking sector. Larger size generally enables a company to benefit from economies of scale and offer a wider range of services. ” Size also facilitates the gathering of information that plays a crucial role in the markets. The bulk of financial flows pass through these groups (see above on the share of volumes on the foreign exchange market), who naturally exploit this dominant position. This information is not public, which clearly creates an asymmetry between players. “In addition to these traditional arguments, however, banks have every interest in increasing the size of their balance sheets as much as possible, in order to benefit implicitly from government guarantees in the event of financial difficulties: this is the famous moral hazard problem of the too-big-to-fail principle, which the bank resolution mechanisms set up under the Banking Union in Europe and the Dodd-Frank Act in the United States are trying to remedy. Let’s also recognize that governments, particularly in Europe, have never really sought to limit the size of banks, and have instead encouraged mergers to create “national champions” in a context of competition between financial centers.

Beyond the banking sector itself, recent decades have also seen the development of collective savings management. Individuals are managing their financial assets less and less directly, entrusting them to professional institutional investors (notably pension funds, insurance companies and sovereign wealth funds). These players have grown considerably in importance since the 1980s, in line with the financialization of the economy. For example, the assets managed by insurance companies, which amounted to some $519 billion in 1980, will reach $34,000 billion in 2019. For pension funds, the figure has risen over the same period from $860 billion to $39,000 billion. Beyond this explosion in assets under management, these sectors are also highly concentrated, as demonstrated, for example, by the fact that the FSB is also developing indicators to identify systemic insurers (even if this is being done with a delay compared to the work of a similar nature done for the banking sector).

Finally, the asset management sector is emblematic of this concentration in the financial sector. Assets under management have almost doubled in less than 10 years, reaching $104.4 trillion at the end of 2019.

This sector is characterized by hyper-concentration at the top: Black Rock, the largest, managed $7,800 billion in assets in 2020. The top 20 asset managers account for 43% of funds under management.

As economist Olivier Passet points out: “Between them, BlackRock, Vanguard and State Street control 25% of the voting rights of the 500 largest US-listed groups and manage 10% of the world’s market capitalization. Shareholder governance is under the tutelage of global behemoths that the crisis has propelled even higher.

Tax havens are an unacceptable source of tax losses for governments

Tax havens are countries or territories in which certain taxes are very low or non-existent and which are characterized by a high degree of opacity. 36 . Their importance has grown with financial globalization. The free movement of capital has reduced controls and facilitated the movement of capital, including for tax evasion purposes (and, of course, money laundering). Financial institutions and law firms established in these countries offer their services to wealthy individuals and multinationals from all over the world. You only have to try to understand offshore schemes to see just how sophisticated the financial techniques used are.

A few definitions

Tax evasion: A strategy for avoiding taxes by placing some or all of one’s assets in low-tax countries, without expatriating there. Tax avoidance can be either tax optimization (legal) or tax evasion (illegal).

Tax optimization: The use of legal means to reduce or even avoid tax liability. It requires a good knowledge of the law and its loopholes. It is practiced by both individuals and companies, often multinationals.

Tax fraud: The use of illegal means to reduce or evade taxes. Moving capital to foreign jurisdictions without notifying the tax authorities is a form of tax fraud.

Source These definitions are taken from the Lexique des Paradise Papers available on the Le Monde.fr website .

Tax evasion (see box) has become better known and understood since the proliferation of cases, investigations and revelations that followed the 2008 crisis. 37 . These led to the mobilization of several countries and international bodies to collect data on a phenomenon that had previously been largely opaque 38 .

A huge loss of revenue for governments

In their research Missing Profits, published in 2022, economists Thomas Tørsløv, Ludvig Wier and Gabriel Zucman estimate that, on a global scale, “almost 40% of multinationals’ profits (nearly $1,000 billion in 2019) are hidden in tax havens every year”. For France, this represents a loss of tax revenue of over $13 billion.

Gabriel Zucman also estimates that the wealth of individuals hidden in tax havens “costs” governments $155 billion a year. “Almost half of the wealth relocated to tax havens belongs to the wealthiest 0.01% of the population in wealthy countries. In the UK, Spain and France, around 30% to 40% of the wealth of these households is domiciled abroad.”

In this respect, the European Union is in a difficult position: on the one hand, increased competition between countries since the 1980s has led to a radical drop in corporate tax rates, from an average of 49% to 24% in 2018. On the other hand, and above all, since its creation, it has been home to tax havens such as Luxembourg and Ireland, without wishing to acknowledge it.

Banks are at the heart of the process, not only by facilitating their customers’ tax avoidance practices, but also by locating their own profits in tax havens. A study shows that in 2015, tax havens accounted for 18% of the foreign sales and 29% of the foreign profits of the 36 biggest banks, compared with just 9% of the workforce they employ abroad 39 . These figures clearly show that a significant proportion of their business and profits are artificially transferred there.

Tax evasion is a major factor in increasing inequality

Clearly, it’s the wealthiest individuals who benefit the most, whether directly by avoiding taxes, or indirectly through the higher profits of the companies whose shares they own. On the other hand, the loss of tax revenue has to be compensated either by raising taxes on the middle classes, or by cutting public spending (and therefore public services accessible to all citizens). Scandals and revelations are therefore also a source of growing social protest: when governments want to cut public spending or raise taxes, in the name of budgetary rigor, tax evasion comes as an even greater shock. Finally, tax havens lead us to underestimate the level and growth of global inequality. Wealth invested in tax havens disappears from the statistical radar, and in particular from national accounts and tax returns.

Markets won’t finance the ecological transition on their own

Facing up to the ecological and social challenges of the 21st century implies a profound transformation of our development model in order to distribute resources more equitably, drastically reduce greenhouse gas emissions, save natural resources, depollute water and rehabilitate soil.

To achieve this, we need to invest massively in new infrastructures where they are lacking, and in bringing existing ones into line with ecological standards. Transport, energy and water infrastructures, fleets of vehicles, aircraft and ships, fleets of buildings, stocks of machinery: it’s our entire stock of physical capital, our entire economic heritage, that needs to be renovated, restructured and sometimes even destroyed to limit the exploitation of natural resources and GHG emissions. We also need to invest in education, training and R&D, in order to support the professional transition of those working today in activities such as the fossil fuel industries, which will not be able to continue if the transition takes place.

As a result, the financial requirements are extremely substantial, amounting to trillions of dollars worldwide. Many are betting on green finance, i.e. on the fact that investors will make their investments according to ecological criteria, notably due to regulatory developments such as the obligation to disclose the environmental impact of financing.

A number of factors cast doubt on the ability of the financial markets alone to finance the ecological transition.

Financial markets are driven by the search for short-term returns

Firstly, given the current state of the capital markets, it is highly unlikely that public interest considerations will take precedence over the short-term return objectives of financial players. As noted in Essentiel 4, the vast majority of the financial system is 40 less focused on financing new investments than on buying existing assets (i.e. on the secondary market) with a view to generating capital gains through rising asset prices.

These are the words of the experts of the High Level Expert Group on Sustainable Finance (HLEG), mandated by the European Commission to make proposals for the implementation of a Europe-wide sustainable finance strategy. “Strategic frameworks and market behaviors continue to favor a focus on liquid assets, short-term financial instruments and returns, and low-profitability debt in a low-interest-rate environment. On the other hand, investments in infrastructure, small-cap indices, SMEs, tritrisation, private equity and real assets are more limited. Yet these assets are often critical to the transition to sustainable development. 41 .

Changing these short-termist practices would require far more far-reaching regulatory and tax changes than have been implemented to date. For example, measures would need to be taken to reduce purely speculative investments and leverage.

Moreover, it’s not just a question of putting the financial world back at the service of the productive economy, it’s also necessary to specifically target investments conducive to a low-carbon economy that consumes fewer natural resources. This would mean going far beyond current measures, which focus on extra-financial reporting by companies and financial institutions, in line with the received wisdom that well-informed markets will correctly orient financial capital (see Received wisdom 1). A much more consistent mobilization of monetary and prudential policies to integrate environmental criteria would appear to be a prerequisite for any real reorientation of financial flows. 42 .

Financial markets are not suited to financing many transition projects

Even assuming that the above obstacles have been overcome, two additional characteristics of transition projects cast doubt on the wisdom of relying on capital markets alone to finance the ecological transition.

First of all, many ecological transition projects are too unprofitable or even unprofitable under current economic conditions, which do not properly value the ecological and social impacts (e.g. soil decontamination activities, developments to create ecological continuities, wetland restoration). Furthermore, some projects are profitable in the long term, but the populations concerned do not have the means to invest. This is the case, for example, of energy-efficient building renovation, which is profitable in the long term thanks to the savings made on energy bills, but whose owners or occupants are low-income households. These investments require a combination of public funding (often in the form of subsidies) and regulatory obligations. Markets are of little help.

Finally, it should be noted that a large proportion of transition project sponsors do not have access to market finance. This is the case for households who want to renovate their homes, farmers who need to radically change their practices, or non-innovative SMEs who need to renew their production tools. It’s also the case for small local authorities: the renovation of their public buildings is on the order of a few million euros, an insufficient size to reach the financial markets, which handle transactions worth at least tens of millions of euros.

Preconceived notions

Financial markets are efficient

In 1970, Eugène Fama coined the term “market efficiency”. 43 (” efficiency market hypothesis “, EMH) and is said to have “demonstrated” that financial markets are efficient.

This expression has since been widely used, disseminated and discussed in the financial world. In particular, it has given rise to the idea that if public authorities, regulators or supervisors observe a “problem” (as in the case of climate change, which is clearly not taken into account by the financial sector, see Essentiel 7), they do not have to act on any other level than that of information. In particular, they do not have to create regulations to ensure that market players take the problem in question into account. If the right information is known to the financial markets, as they operate “efficiently”, they will play their role correctly.

Efficient is an ambiguous term. Seen from a non-specialist’s point of view, the above argument suggests that financial markets are fulfilling the mission that public opinion intuitively gives them: they allocate “capital” (to simplify, savings) efficiently, i.e. to the companies or projects that are “best” for society. However, for neo-classical economists, this idea refers to the notion of optimality as defined by Vilfredo Pareto: a situation is optimal when it is not possible to improve the situation of one actor without disadvantaging another. Clearly, the question of distribution has nothing to do with it: a situation where A has everything and B nothing, can be efficient in Pareto’s sense, which is hardly in line with common intuition, and is not without raising questions: if the “economic efficiency of markets” can lead to unfair situations, then public regulations are needed to correct them.

In any case, and this may seem strange for a theory based on a mathematical model and awarded the Nobel Prize in 2013, Fama’s use of the term “efficiency” is ambiguous, and his “demonstration” does not prove that markets are efficient in the sense of optimal allocation of savings. Yet he himself evokes this sense at the start of his seminal article:

“The very first role of the capital market is to allocate ownership of the economy’s capital stock. In general terms, the ideal is a market in which prices provide appropriate(accurate) signals for the allocation of resources”.

However, this is not the thrust of the article (nor of subsequent works). It focuses on another question, without convincingly demonstrating the link with the previous one: that of “informational” efficiency. But here, too, it is not very clear.

Robert Shiller 44 who was awarded the Nobel Prize at the same time as Eugène Fama (even though he is one of the economists convinced of the inefficiency of markets…), distinguishes between three meanings:

Zero arbitrage efficiency: “no pain, no gain

This is what Eugène Fama formulated in 1991: a market is efficient if profitable forecasting is impossible for market participants. 45 . This idea is taken for granted in the trading world, which takes for granted what is known as the “absence of arbitrage opportunities”: there is no financial strategy which, for zero initial cost and therefore without taking any risk, can acquire certain wealth: the future of the markets is unpredictable. Buying a financial asset in order to resell it is therefore risky… We can call this efficiency “zero arbitrage efficiency”.

This empirical finding lies at the heart of the debate between active and passive management. 46 . In short, if markets were efficient (in this sense of the word), wouldn’t it be better for financial investors to entrust their funds to a “passive” manager who simply “follows” or “replicates” the market. Management fees would be lower, and results better on average… or at least less risky.

The rise of passive management is not unrelated to the widespread belief that “markets are efficient” (always in this sense). Unfortunately, it is probably in itself a source of increased systemic risk. Indeed, the alignment of investor behaviour (via the asset managers to whom they entrust their funds) as a result of this passive management can intrinsically lead to the formation of bubbles. To put it another way, this “zero arbitrage efficiency” not only cannot be confused with informational efficiency, but can also induce behaviours that make market information less efficient… So to speak of efficiency here is clearly a misuse of language.

Informational efficiency: “prices are right”.

In his 1970 text, Eugène Fama wrote: ” A market in which prices always ‘fully reflect’ available information is called ‘efficient’. ” This then led to more precise definitions, thanks to which statistical tests were constructed in an attempt to decide whether a given market was or was not strongly or weakly efficient. 47 and debate. Low efficiency means that the current price incorporates all information on past prices of the asset concerned. If this condition is satisfied, technical analysis of the historical price series cannot lead to any profit. In semi-strong efficiency, the price contains all publicly available information. The evolution of other assets cannot, through their correlations with the asset under study, provide opportunities for profit. In the case of strong efficiency, the price contains all the public or private economic information that the market has taken into account and digested, including insider knowledge.

In practical terms, this literature does not allow us to draw any clear, usable conclusions. The value of an asset is a debatable notion (unlike its price in a transaction, which is observable at a given point in time). According to standard financial theory, the value of an asset is the discounted sum of the future cashflows it generates. This definition is clear, but its practical application depends on the assumptions made about these cash flows and the discount rate. According to Fama, the financial markets would reveal this value. If this were true, it would eventually start to fluctuate sharply when a speculative bubble bursts. If the markets had been right before the bubble burst (indicating a very high value), how could they still be right afterwards (the value having become lower)? The answer is that new information may have come to light. This is indeed the case: when markets turn around, it’s because market participants’ expectations are shifting massively (and vice versa, market movements move expectations…). But does this have anything to do with the value of a given asset? We doubt it.

Before going any further, let’s emphasize two points:

1 Eugène Fama’s model is based on an assumption of “rational” behavior on the part of economic agents, which has been challenged by the work of behavioral economists (and, more generally, by most of the work in social psychology). Ironically, Robert Shiller challenged this work thanks to the use of Lars Peter Hansen’s statistical tools (the third Nobel Prize winner, in the same year as Fama and Shiller…).

2 Benoît Mandelbrot, (mathematician, inventor of fractals) has shown, based on the analysis of empirical data, that the assumption (used in Eugene Fama’s modeling and above all in most financial calculations) that movements on financial markets obey so-called “normal” or Gaussian probability laws (in other words, follow Brownian motion) is simply false. 48 . This is one of the reasons why financial crises occur more often and on a greater scale than predicted by efficiency theories. This is demonstrated by the scale and repetition of financial crises since markets were freed up, decompartmentalized and deregulated (see Essentiel 3).

Finally, let’s note that there is still a huge gap to be bridged between asserting that “prices are right”, assuming that this is true, and demonstrating that markets would allocate capital correctly for the economy to be efficient (allocative efficiency), the third possible meaning of the term efficiency to which we will now return.

Allocative efficiency: “financial markets would lead to an optimal allocation of capital”.

In this sense, Robert Shiller has shown that financial markets are not efficient. On the one hand, based on the observation of their volatility and their sometimes exuberant behaviour 49 . Secondly, through careful empirical work (see curve below), which shows a clear decoupling between company values (market capitalization, in this case of the SP index) and the income paid out to security holders (in the form of dividends). The value of companies on the financial markets is quite simply disconnected from their ability to enrich their shareholders.

Stock price index

This being the case, if this decoupling were not observed, we could simply deduce that the financial markets correctly inform “investors” of the return prospects of the securities they buy or sell. This would in no way allow us to conclude that these financing decisions enable an optimal allocation of capital in the sense that they would lead to a state of the economy that is optimal from the point of view of the societal objectives pursued.

In conclusion, Eugene Fama has pulled off a masterstroke: he has succeeded in making people believe that markets are a forum for the efficient allocation of capital, whereas his theory is irrelevant to this central political issue.

Derivatives and speculation stabilize markets

Like the previous one, this idea expresses a belief in the efficiency of financial markets. The idea, put forward by Milton Friedman, seems almost common sense. The good “speculator” (the one who hedges the risk not taken by other economic agents) buys when prices are low and sells when prices are high. Their action will therefore regulate the market and contribute to the general interest.

This irenic vision is far from reality. As we saw in Essentiel 5, price turbulence remains high. Not only does financial activity not stabilize prices, it can also destabilize them, especially in times of stress. Financial asset prices can become delirious (just before a financial bubble bursts). Financial crises have become much more frequent since financial liberalization (see Essentiel 3) and the explosion of derivatives.

Market financing of the economy should always be favored over bank lending

In Europe, companies are mainly financed by bank loans, whereas in the United States they are mainly financed by access to the market. 50 . The logical consequence of the belief in the ability of markets to allocate capital efficiently (see preconceived notion 1) has led the European Union to follow the American example and build a ” single capital market “.

This project was accelerated during the COVID crisis to facilitate company financing. 51 . In view of the foregoing analysis, we may well doubt its value, and even wonder why it is considered one of Europe’s major projects. If the big banks are pushing it, it’s because it’s in their own interests: it’s more profitable for them to be paid in consultancy fees or commissions than in interest on corporate loans, especially when interest rates are very low.

The State should not intervene in the financing of the economy

The belief in the efficiency of financial markets (see Myth 1), coupled with the belief that printing money is the worst evil of all(see the module on money) when it is in the hands of the State, logically leads us to believe that financing the economy should be left entirely in the hands of the private sector.

This belief even leads us to consider that the State and public administrations must also finance themselves on the markets, to submit to their discipline in order to avoid the risks of waste and clientelist management that would automatically result from too easy recourse to “printing money”(see the module on money).

While there may be doubts about the relevance of nationalizing credit and economic financing, it is not, conversely, rational to consider that only the private sector is appropriate to do so.

Let’s summarize the main reasons:

  • the market is subject to the “moods” of players, which makes it volatile, inconstant and liable to generate violent crises
  • it does not take the long term into account (this is the “tragedy of horizons” highlighted by Mark Carney) (see Essential 7)
  • it does not take into account what is “non-market”, starting with nature and social inequalities, and more generally the balance of society

Public authorities must therefore intervene in a number of ways: by regulating banking and financial activity to reduce financial instability and steer financing more towards the productive economy; by directly financing activities of general interest, which the private sector is unable to finance due to lack of financial profitability; by using regulatory and tax tools to improve the profitability of companies and ecological transition projects, and to reduce the profitability or even ban high-carbon industries that consume natural resources.

Finance and financial innovation foster economic development

The development of the financial sector, like that of any other business, creates jobs. What’s more, the economy as a whole needs finance in the broadest sense (banking, insurance, finance). But there’s nothing mechanical about the link between financial sector growth and GDP.

Financialization can harm economic activity

A number of recent empirical studies attest to the fact that hyper-financialization is detrimental to economic growth 52 . More precisely, the development of finance supports growth in economies characterized by a low level of development of the financial sphere – developing countries – but weighs on growth in economies where the finance sector is highly developed. The diagnosis common to all these studies is that there is a threshold in the development of finance beyond which it becomes predatory on the real economy. Most developed economies are well beyond this threshold, whatever the metric used in the various studies.

The negative effects of too large a financial sector are manifold: it deprives other sectors of the “talent” attracted by financial sector revenues, increases in inequality, diverts financing from the productive economy to purely speculative investments, shortens companies’ time horizons, increases the volatility of commodity prices, etc. (see Essentiel 5).

Some financial innovations are dangerous for the economy

As far as financial innovation is concerned, we can see that there are good financial products and services (which cover real risks) and that there are some that are socially useless or even dangerous.

Socially useful products and services include insurance against real risks (comprehensive home insurance, third-party liability, etc.), bank loans, term insurance and certain simple coverages…

Among the products and services that are useless or even dangerous, we can cite the following:

  • High-frequency trading, in which computer algorithms execute financial transactions at very high speed.

The aim of high-frequency trading is to generate very small gains on each transaction, while at the same time multiplying the number of transactions, so that substantial profits are generated in the end. High-frequency trading is said to account for a large share of the volume on the various stock market platforms. In 2017, this share would be around 60% of volume on the US equity market, 40% of volume on the European equity market, and around 30% of volume on the Asian equity market. 53 . It is often defended on the grounds that it would guarantee market liquidity, thereby helping to improve the market’s degree of efficiency, to the benefit of all investors… (see idée reçue sur l’efficience des marchés). However, it is highly questionable. Because of its energy consumption, it has a disastrous carbon footprint. It is also criticized for its potential for price manipulation, and for increasing market instability.

We quote economist Gaël Giraud, who stresses the risk of insider trading 54  :

“A piece of information sent out, “inadvertently”, five hundredths of a second before its official publication can be processed by fast computers with a lead time over their competitors comparable to the few hours which, in the old world where the time step was the minute, were sufficient to constitute insider trading. 55 . Better still, there is now a trade in information sold a few seconds before its public release. Reuters, for example, bought the right to transmit the consumer confidence index (calculated by the University of Michigan) to some of its clients two seconds before its official release, for one million dollars a year. Insider trading has become a legal industry.”

  • CDS exposed

Credit default swaps (CDSs) are hedging contracts against the risk of default by a company or a country. Sovereign CDS apply to government debt: they act as insurance contracts, triggering payment in the event of a country’s default.

In the case of “naked” sovereign CDS, these insurances are traded without investors holding the corresponding debt securities, meaning that they benefit from the insurance, without the risk. They are instruments of speculation against governments. The price of naked CDS tends to rise when the market speculates on the risk of default by the government concerned. Naked sovereign CDS were banned in the eurozone from November 2012, following the Greek speculative crisis.

  • Securities borrowing to enable securities to be sold short.

A short seller (often a hedge fund) speculates on the downside of a stock. He borrows a company’s shares from an investor and sells them on the market. He then repays this share loan by buying shares. These various operations enable him to record a gain if, as he had anticipated, the share price has fallen in the meantime. And he’s not the only one to gain, since he pays interest to the financial player (an asset manager, for example) from whom he borrowed the shares.

This practice is a source of substantial revenue, and can be highly destabilizing both for the companies “attacked” and for the markets as a whole. The GameStop affair (where small shareholders tried to resist the short-sellers by buying up the company’s shares en masse) clearly shows that these operations are nothing more than speculative games with no social interest.

Green or sustainable finance would be sufficient to achieve the ecological transition

There is a side to finance that is not exclusively focused on the quest for financial gain.

According to economists like Milton Friedman, the exclusive pursuit of financial self-interest by everyone (and for companies, the quest to maximize “shareholder value”) is the only way to optimize satisfaction for all. This “theory” is false in its generality.

As far as finance is concerned, this is not only false, but dangerous, given the sector’s special role in the economy as a whole. The focus of financial players on the risk/return trade-off alone (see Essentiel 1) leads economic agents who are dependent on bankers and financiers to exclude other aspects of economic and social life, as well as the consequences of decisions taken on climate and ecosystems, from their thinking and decision-making.

This belief in the need for the financial sector to focus on its core business of managing financial risk has not, however, prevented the emergence of a financial sector that integrates social and environmental concerns.

Under pressure from public opinion and NGOs, and in the wake of major social battles, some financial players have gradually developed practices such as exclusion and shareholder engagement (see box), the integration of ESG (environmental, social and governance) criteria into investment policy, or the definition of thematic or multi-theme funds targeting companies or projects according to their precise environmental or social impacts.

Exclusion and shareholder engagement

Historically, the exclusion of ethically controversial activities (alcohol, tobacco, arms) from the financial portfolios of companies. In the early 20th century, some American religious congregations refused to invest in alcohol and tobacco. These practices then developed during major social struggles, such as the fight against the Vietnam War or the apartheid regime in South Africa. More recently, the practice has developed in the environmental field, in particular with vast campaigns to divest from fossil fuel industries, starting with coal.

Shareholder engagement involves using the voting rights associated with holding shares in a company to influence it towards social, environmental or governance improvements. This involves regular dialogue between investors and the company’s management, then, if this is unsuccessful, voting on a resolution at the Annual General Meeting, refusing to vote on the accounts and , ultimately, divestment.

At the same time, regulations and market practices have developed to look beyond companies’ economic performance indicators and measure their impact on society and the environment. Begun in the 2000s with the French NRE law, the demand for reporting 56 was initially limited to the publication of non-financial indicators.

Recognition of systemic climate risks amplifies the trend

Recent awareness of the systemic financial risks following global warming (see Essentiel 7) has helped to amplify the movement in the climate field, with in particular the publication in 2017 of the report by the Task Force on Climate-related Financial Disclosures (TCFD). Set up by the Financial Stability Board 5 the TCFD proposes an international corporate reporting framework to enable investors to better assess and report on the climate-related financial risks borne by the companies in which they invest. It adds a much more strategic dimension to climate reporting, recommending that companies report on how climate-related risks and opportunities are taken into account in governance, strategy and risk management processes.

This evolution in reporting is also noticeable among financial players. Driven by regulations 57 and market practices, financial players are increasingly required to assess and report on the climate risks of the assets in their financial portfolios. This is leading some banks and insurance companies to adopt “sectoral policies” excluding certain sectors with high exposure to coal in particular. It is also leading institutional investors and asset managers to measure the carbon footprint of their portfolios and take action to reduce it. A whole range of new management methods are developing under the pressure of climate issues.

Green finance alone cannot make a significant contribution to the ecological transition

However, this “new” finance (called responsible finance or green finance for its environmental dimension) cannot by itself have a significant effect on the transition without public regulation that goes far beyond mere reporting.

On the one hand, financial players have a fiduciary responsibility to make money for their principals. But “sustainable” is not necessarily profitable in the short term. They can therefore be criticized (or even legally attacked) for not respecting the mandate given to them.

On the other hand, competition between financial players prevents them from substantially reducing their profitability (which they would have to do for ethical or environmental reasons). There are therefore only two conceivable hypotheses in the absence of public regulation: either this green or sustainable finance is a niche market, a “marketing opportunity” (see box below), or it would be more efficient than traditional finance because it would better integrate risks or opportunities. In this second hypothesis, “sustainable” finance would simply be a way of improving finance as a whole, whose core business is precisely to optimize the risk/return trade-off, and therefore to assess risk as effectively as possible. It would be green in name only. Public regulation is therefore necessary to align profitability and sustainability.

Responsible “responsible in Europe

Depending on the strategy, responsible finance can appear either important or anecdotal. According to EFAMA, assets under management in Europe represented 21,500 billion euros at the end of 2015 59 .

The table below shows that exclusionary practices account for almost 50% of this total, while sustainable thematic funds represent less than 1%. It should be noted that the overall volume of the European financial industry is estimated at 100,000 billion euros in assets.

Assets under management in 2015 by strategy in 13 European countries (in billions of euros)

Assets under management in 2015

Source European SRI Study, 2016 (tables p.56 and 57). The figures in this table are not entirely comparable with the overall volume of assets under management in Europe, as they concern only 13 countries (Austria, Belgium, Denmark, Finland, France, Germany, Italy, Netherlands, Poland, Spain, Sweden, Switzerland, UK). However, given that these are Europe’s main financial centers, they do provide an indication of the scale of the problem.

All we need to do is shift funding from carbon-based industries to green projects

At the economic level, the ecological transition involves replacing the existing stock of productive capital with capital that consumes fewer natural resources (starting with fossil fuels) and causes less pollution (including greenhouse gas emissions). This is as true for collective infrastructures (transport, energy, water, waste, lighting, public buildings, etc.) as it is for individual economic players (housing and services, vehicles, factories, machines). Investment and financing are key issues for the ecological transition.

To a first approximation, the financial stakes are twofold: i/ directing funding towards ecological transition projects, and ii/ at the same time, drying up funding for projects that are incompatible with this transition. This has led many to conclude that it would work like a communicating vessel, simply transferring to “green” projects the funding currently earmarked for “brown” projects. The reality is more complex.

The importance of launching the transition as quickly as possible: the lock-in effect

Transition investments are long-term investments. They are characterized by the long lead times involved in their construction and operation, as in the case of infrastructure, for example. Uncertainty as to their return is therefore often high, which explains why investors may be reluctant to finance them, and hence the need for public intervention. Integrating long-term ecological issues into the investment decision is essential, because of thelock-in effect. Deciding today to build a coal-fired power plant will generate greenhouse gas emissions for the duration of its economic life, i.e. a priori for decades. In fact, closing it down while it is still profitable will lead to financial losses that no-one will be able to afford…

Sectors in which to invest or divest do not necessarily coincide in terms of meeting demand

In L’Edition 2023 des financements climat en France, the think tank I4CE estimates the need for additional climate investments at an average of 58 billion euros per year for the period 2024-2030 (in the building, transport and energy production sectors). In 2023, climate-damaging investments (in the same sectors) amounted to 57 billion euros. So we’re on the same order of magnitude. However, if we look at the actual content, we see that the investment shortfall mainly concerns the renovation of housing and public buildings, while the climate-damaging investments mainly involve the purchase of cars and trucks.

This highlights the fact that it is not possible to envisage a transfer of financing in the short term. Economic agents are not going to stop buying cars to renovate their homes. Additional financing will be needed for the ecological transition if it is to be launched today.

Transition sectors are no more profitable than carbon-based sectors

In many sectors, transition investments are aimed at replacing existing equipment with greener solutions. The economic players of tomorrow are therefore in competition with those who defend existing production and consumption patterns, both globally and within companies themselves. This puts sustainable activities at a disadvantage in two ways. On the one hand, vested interests defending the existing model are powerful, structured and well-established, as demonstrated, for example, by the difficulty many countries have in putting an end to coal mining, even though this is one of the priorities in the fight against global warming. On the other hand, sustainable activities are pitted against activities with mature technologies, widespread skills, amortized investments and existing infrastructures. The existing system sets the “selling price” against which the profitability of the ecological solution is confronted.

For example, “decarbonized” vehicles have no chance of being competitive with combustion-powered vehicles unless we make combustion more expensive and help the decarbonized vehicle industry to catch up: develop R&D for the vehicle itself (bearing in mind that combustion-powered cars benefit from 100 years of experience and tens of thousands of engineers, designers, marketers, etc.) and energy distribution infrastructures (charging stations for electric vehicles).

Financing the stranding of carbon assets

Finally, it’s not just a question of redirecting funding towards ecological transition projects, and stopping the financing of new projects that are incompatible with this transition. It is also essential to divest existing productive capital that is too carbon-intensive (or destructive of natural capital). This means, for example, closing coal-fired power plants. Far from being a transfer of financing, this divestment could ultimately prove very costly, both for private players (it would be the materialization of the risk of “stranded assets” – see Essentiel 7) and for governments if companies seek financial compensation following administrative decisions.

We must not weaken European banks by imposing regulations that are not imposed on their competitors.

This argument is not limited to the banking and finance sector. As a general rule, multinational companies (including the major European banks) aspire to a level playing field throughout the world. This enables them to improve their profits through economies of scale: producing products or services in the same way on larger markets is an obvious source of increased profitability.

But then, in the name of this ” level playing field “, the banks ipso facto push regulations downwards, given that they have no interest in doing the opposite. If, in the name of the general interest, stricter regulations are needed, then it is up to the public authorities to put them in place, against the will of the players involved. The argument then put forward by the banks (as by other players in other sectors) is that they will be weakened in the face of competitors who are not subject to such strict regulations. The authorities’ response can only be to limit this risk and re-establish conditions of fair competition. In the face of the risk of a takeover, for example, as in other strategic sectors, weapons such as takeover bans should be considered.

Excessive constraints would penalize finance, and therefore the economy.

When a lobby wants to oppose regulations or any other form of constraint, it puts forward the risk that this would pose to its activity or even its economic survival (due to the cost to it of these regulations) and therefore to economic activity as a whole. This endangerment argument is a classic, and is one of three highlighted by Albert Hirschmann 61 .

It is clear, as we have tried to show throughout this module, that finance does not spontaneously put itself at the service of the real economy; on the contrary, it has distanced itself from it (see, for example, Essentials 4 and 5).

There is no justification for not regulating financial activities, which might make the sector less profitable but would benefit the economy as a whole.

And more regulation does not necessarily mean greater complexity. For example, we only have to delve into the intricacies of prudential regulation for banks to see how complex it has become, yet how inefficient. But it is also in the interests of the banking sector itself, which benefits from this complexity (see box).

Prudential regulation and the complexity trap

Prudential regulation is extremely complex, and as such is the source of many imbalances.

– It distorts competition between the largest banks and smaller ones. The former have the means to exploit this complexity to their advantage, as demonstrated by the development of internal models enabling them to “optimize” their risk-weighted assets. 62 .

– It provides fertile ground for what is known as “regulator capture” by regulated players. Indeed, the ability to influence regulators involves not only direct lobbying, but also more subtle channels of internalization by supervisors and regulators of the objectives, norms and values of the financial sector, through processes of social identification. “The sophistication of regulation directly influences the composition of the staff of regulatory and supervisory agencies in a way that is favorable to the industry. Regulatory complexity justifies the recruitment of financial experts from the regulated industry. They are supposed to have a better understanding of the technicalities of regulations and the issues at stake, even though they often suffer from a pro-industry bias as a result of their previous careers in the industry.Revolving doors 63 ) are most often justified in terms of technical skills and in-depth knowledge of the sector. 64
