The Current Financial Crisis : something old, something new

A New event or history repeating itself?

Financial crises happen time and again, each time exhibiting a fundamental similarity in their origins and the way in which they unfold, but also in their own specific characteristics. All financial crises take at least one of three canonical forms which history has regularly taught us since the 19th century, at least. Often they take on and combine each of the three forms successively or simultaneously. Let us analyse them, with particular reference to the works of Michel Aglietta and the economists at the Bank of International Settlements.

The first and oldest of these forms is the speculation crisis. Why do property assets (shares, real estate…) become the subject of speculative bubbles? Because their price, in contrast to goods, industrial services or repeatable trade, does not depend on their production cost. That is why their price can be some way off their manufacturing costs. The price of a financial asset depends fundamentally on the confidence we place in it based on the future returns it can bring as forecast by its issuer. But the determination of price also depends on what everyone anticipates regarding the confidence placed in this promise by others. Everyone reasons in this way.

If the information is not fairly shared (between lender and borrower, the shareholder and the management, or between the market actors themselves), coupled with the fact that the future is difficult to predict, these information asymmetries and the fundamental uncertainty favours mimicry in the parties. So it is in fact very difficult to know the fundamental value of the asset in consideration, and so also to bet on it. In this case, the direction of the market is decided by the others because it is the pure product of expression of the majority opinion which then becomes clear. So the parties understandably imitate each other, hoping to try and anticipate and go with market trends in a totally self-referring manner. Thus these bubbles can burst suddenly, with the reversal of the majority opinion, in an even stronger movement than that which characterised the previous phase.

The second form, the credit crisis, stems from the fact that over a prolonged growth period all parties (banks and borrowers) progressively forget about the possibility of crisis occurring and end up expecting unbounded growth (an effect of “disaster myopia”) . In this euphoric state, lenders dangerously lose their sensitivity to risk and the level of leverage (debts on the level of wealth or of household revenue or of net assets for businesses) and end up increasing excessively.

Besides, this phenomenon is considerably amplified where lenders no longer gauge the solvency of the borrowers against the yardstick of their likely future revenues, but against the yardstick of the expected value of the financed assets (notably shares or property) or which serve as collateral. In the end, and more often than not, during this phase they accept margins that do not cover the cost of risk of forthcoming credit, as is the competitive nature of the game.

The financial situation for the economic agents proves very vulnerable during the next economic reversal. Also, while the crisis is happening, the lenders (banks and markets) carefully reconsider the level of risk they are running, and by a symmetrical effect of the precedent, they sharply reverse their practice of credit grants, as much in terms of volume as margin, until they provoke a “credit crunch” which will itself reinforce the economic crisis that it has created.

The third canonical form of crisis; the liquidity crisis. During a certain dramatic sequence of financial crisis events, a contagious wariness appears as we are witnessing with today’s financial and banking crisis. For certain banks this defiance induces a fatal rush in their clients to withdraw their deposits. It can also lead to a rarefaction, even a disappearance of willingness with the banks to lend to each other for fear of a chain of banking bankruptcies. But this illiquidity in the market of inter-banking finance – without the last resort intervention of the central Banks in the role of lenders – produces these bankruptcies which are so dreaded. Apart from this, other forms of illiquidity can be produced.

Certain financial markets which yesterday were fluid can suddenly become illiquid; so much so that the concept of market liquidity is still highly self-referential, as André Orléan has analysed. A market is only liquid if all the parties involved believe it to be. If suspicion arises as to its liquidity, as was recently the case with the ABS market for example, all parties will find themselves selling to get out of the market, at the same time provoking its illiquidity in an endogenous fashion.

These three types of crisis are often interlaced and mutually lead to an extremely critical situation. As an example, credit can quickly grow excessively by virtue of the unusually high growth in the price of property assets which act as guarantees to these funds. And the prices of these assets shoot up themselves since easier credits allow for additional purchases.

Here we end up faced with a self-maintaining and potentially long-lasting phenomenon in markets which do not stabilise themselves at normal levels. Likewise the liquidity crisis is generated, for example, by a sudden fear over the value of bank debts and the financial assets which the financial organisations possess. In the search for liquid assets the banks will finance the economy less and try to sell their assets, which in turn worsens the speculative crisis as with the credit crunch.

The major crisis which began in 2007 is a combination of these three forms. Firstly a speculative property bubble, notably in the US, the UK and Spain. Next, a credit crisis due to a dangerous rise in the levels of household debt in these same countries, and to a very high leveraging from the investment banks, businesses in leverage buyout and hedge funds in particular. Finally a liquidity crisis in the securities products and inter-bank refinancing markets.

Each crisis reinforces the other two in a self-maintaining process.
The idiosyncratic element of the current crisis lies in the rapid development in securitisation of bank debts in recent years.
Securitisation comes from the credit organisation report of bank debts for individuals, businesses and local authorities. These debts are often grouped in a heterogeneous manner into supports with a high leveraging effect themselves, revenue supports to other banks, to insurers and to displacement funds, in other words ultimately for everyone.

Securitisation has therefore enabled significant growth in the financing of the global economy since it allows the banks to make much more funding than if they’d kept them in their balance sheet. But this technique, which is not controlled, has also incited the banks who use it most (particularly in the US) to considerably lower their selection standards and their monitoring of borrowers, and to agree to lend to increasingly insolvent borrowers because they then run no more risk after securitisation. So, for example it’s in this way that sub-prime credit liabilities multiply, significantly increasing the credit crisis which has come about following the bursting of the property bubble.

Non-regulated securitisation has then considerably aggravated the credit crisis, but also the liquidity crisis. In effect the difficulty in tracking these funds and the mixture of good and bad credits in the same supports, like the opaqueness and complexity (CDO…) of securities products, have in turn worsened the extent of the crisis itself. With everyone losing all confidence in the quality and even in their understanding of this kind of investment, their liquidity has in fact found itself suddenly dried up. In fear of the assets then being held in the banks’ balance sheet, and so those of the insurers, at the same time this has led in particular to an inter-bank liquidity crisis of a gravity that we thought had been consigned to the past. For public authorities the difficulty in resolving the problems which have arisen has increased.

Finally, the credit-rating agencies, armed with unappreciated mathematical models based on restrictive hypotheses and the exclusive analysis of past series, have accorded a quality grading (grade AAA) to sections of the supports in question. And yet this seal of approval has revealed itself little by little, as the crisis unfolds, to be of very poor quality. These grades, which moreover do not account for the risk of liquidity, have led many investors including bankers to reassure themselves of getting off lightly, and in the end wrongly, on the quality of their financial assets, without asking themselves overly about the reasons for which an AAA investment quotation could be so well compensated.

The entanglement of these three canonical forms of financial crisis, other specific elements and the current crisis explain the extreme seriousness of today’s situation, with its procession of banks in distress, the panic of investors, the “credit crunch” in process, and finally the powerful economic crisis. Only the strong actions of the authorities, at the precise moment when everyone doubts each other, has recently been able to begin to calm the inter-bank market a little and to avoid a total collapse of the financial system.
All that remains is to watch for, and try to counter, the economic consequences of the most serious financial and banking crisis since the ‘30’s. And to hope that the resultant risk of credit to businesses and households does not revive the banking crisis in a vicious circle which would once again exacerbate the coming recession.

The question of price volatility in financial assets

Financial market volatility has increased since the advent of globalisation and is undermining the real economy. At the same time, it is generally accepted that the non-correlation or low correlation of the various markets allows for portfolio diversification, improving return for an identical risk or reducing risk for a given level of return. But all such matters require much closer attention.

The volatility of a price or return is commonly accepted to be representative of the level of inherent risk in a market. Accordingly, the higher the volatility of an asset or market, the higher the risk of investing in the said asset or market. Volatility is calculated by the square root of the price variance (the standard deviation), i.e. by measuring the deviations in the price vis-à-vis its average value over a given period. Accordingly, a security whose price has increased or decreased in a regular manner over a given period is said to show low volatility. Conversely, if it has decreased or increased in overall terms in an irregular manner, with significant and numerous rises and falls over the given time period, it is deemed to show high volatility. With good financial logic it is legitimate to expect higher returns from a high-volatility security in advance.

We shall not enter here into the debate as to whether a measurement that treats gains and losses in a market in an equal manner provides an appropriate indicator of the risk taken by the parties, given that the latter tend to be more worried about losses than they are satisfied with gains. We shall concentrate on the issue of the existence or otherwise of increasing and excessive volatility since financial markets were opened up and deregulated in the 70s and 80s, and on the diversity and non-correlation of the volatility required for effective portfolio diversification.

In a somewhat paradoxical manner it can be maintained that, in equity markets for example, although volatility itself is highly volatile:

  • Its trend has not actually increased since the progressive introduction of financial globalisation, nor over a much longer time span, namely since the late 19th century;
  • Following the opening-up and deregulation of financial markets, however, it has shown a very marked increase in comparison to economic fundamentals (GDP growth and inflation), which justifies talk of excessive financial volatility.

This paradox can be easily explained if we expand the concept of volatility. The result of the calculation will obviously not produce the same signal if we vary the chosen frequency (such as daily or quarterly variation) or the period over which the volatility is measured (over a week or decade, for example). If we select a daily frequency for measuring the variation in the Dow Jones index, for example, and a weekly time period to measure the volatility of this variation, the first assertion can be verified. This means that the volatility trend in the equity market has not grown since the 1970s or 1980s nor, for that matter, since the late 19th century. In other words, daily price variation, measured over one week, has not been any higher on average in recent decades than in previous times. However, measured in this way volatility was naturally much higher, notably between 1929 and 1932, in 1987 and in 2001-2002 than in other periods*.

Such a frequency and timeline does not allow any judgement to be made on the comparative volatility of financial markets and economic fundamentals, as growth and inflation rates are only measured at lower frequency and only vary significantly over longer time periods. Additionally, a quarterly frequency and a timeline of a decade make it possible to adopt a pertinent approach to this question. A study into the volatility of actual financial variables was carried out by P. Artus (“Flash” no. 41 from February 2004, CDC Ixis). The figures below have been taken from this study.

Macro-economic regulation

Let us first of all be clear that such volatility measured for growth (GDP) has been relatively stable since 1960, with lower levels seen in the latter period (1980-2003) in the United States, and since the decade 1980-1989 in France and Germany, for example. As for inflation, its volatility is a little higher and variable than that of growth, with a peak in the decade 1980-1989 due to the strong deflationary phase experienced internationally. Accordingly, in both the USA (1960-2003) and in France (1970-2003), growth volatility lies within the 1.3% to 2.7% range and, for inflation, between 0.6% and 4.3%, with very low historical levels for both in the latter period. Finally, short and long-term interest rates have not seen higher volatility than that of growth and inflation.

This cannot be said for exchange rate and equities volatility, which increased sharply over the period under analysis. The effective nominal exchange rate for the dollar (weighted against the main partner country currencies) has seen its volatility multiply by a factor of 5 between 1970-1979 and 1960-1969, clearly explained by the end of the Bretton Woods system.

Fundamentally, financial stability is a collective asset, one which is vital for the proper functioning of all decentralised market economies.

This volatility once again nearly doubled over the following decade, reaching a level of 16.8%, but falling back down to 8% over the period 1990-2003.

The real stock market index volatility in the USA ranges from 11% to 18.5% between the decades 1960-1969 and 1980-1989 and rises abruptly to 82.6% over the period 1990-2003. In France and Germany, a similar phenomenon can also be observed. We can therefore assert without fear of contradiction that over the latter period there has been excessive equity market volatility compared to growth (around 1.5%) and inflation (around 0.6%). If we compare equities volatility to that of dividends in order to select a fundamental more directly associated with equities, we once again see the excessive volatility in equity markets

This excess clearly poses the question of instant pricing in markets which, according to efficient market theory, should be valid indicators of the fundamental or equilibrium values of financial assets. When price volatility as recorded on the equity markets, for example, is much higher than that of growth, inflation or long-term interest rates, the spot prices set by supply and demand lose pertinence and can legitimately be considered at certain times to be the result of disruptive speculative bubbles.

Accordingly, very short-term financial volatility that has not risen tendentially over a very long period can co-exist with medium-term volatility, notably in equity markets, at a much higher level than that of the fundamentals for the latter period under study.
The fact remains that financial theory justifiably teaches us that good portfolio diversification allows such volatility to be managed when there is total or partial decorrelation between the various financial markets.

A good selection of diversified assets, for example, should entail lower risk – and therefore lower volatility – for the whole portfolio with equivalent return expectations. But the 1980s and subsequent decades have unfortunately demonstrated that such diversification only brings its benefits in calm waters, not at times of serious financial crisis, i.e. when it is least needed. During stormy times such as during major financial crashes, volatility in the various financial markets (private bond spreads, stock markets in different geographical regions, emerging economy currencies, etc.) show the marked tendency to correlate abruptly in an upwards direction. The benefit of diversification and the ability to manage relatively high financial volatility falls off sharply, or even completely disappears.

The question of (excessive) financial volatility cannot, therefore, solely be managed by appropriate micro-economic measures. It remains a question of global macro-economic regulation. Fundamentally, financial stability is a collective asset, one which is vital for the proper functioning of all decentralised market economies, and must be managed as such by national and international regulatory bodies.

Measured over very short periods we have experienced financial market volatility that has not shown any upward trend between the late 20th century and today; however, measured over long periods, volatility has indeed grown and has far exceeded that of the fundamental variables supposed to determine the prices of the financial assets themselves. Here we look at the reasons and stress that such high financial volatility cannot simply be managed by portfolio diversification.

Necessity and dangers of the Euro

Article published in the newspaper Le Monde in 1997

The merits of the euro have been thoroughly analysed, although inadequately communicated. However, the introduction of the single currency could well be postponed, and even runs the risk of being aborted. And the major reason for this real threat is precisely the fact that the dangers resulting from the euro have been underestimated for too long. No doubt, the remedies to counter these dangers have not been viewed as adequately profitable in elections.

So, what are these dangers?

The exchange rate is a practical and necessary adjustment variable for a country. Certainly, in some conditions, it is one of the least painful adjustment variables. Does one country experience a so-called asymmetrical crisis that its main partners do not? A devaluation can allow it to re-establish itself with less of a setback, authorising it, by a more nature development of its exports and by acting as a monetary brake on imports, to more easily resume the path to growth. Does one country experience greater inflation than its neighbours? Does a lowering of its exchange rate allow it to maintain its outside competitiveness? There is no question here, however, of promoting devaluation as a cardinal point of any economic policy. But well-managed exchange rate adjustments have managed to prove their effectiveness, and the non-inflationary world in which we live today makes it more effective, as were the cases of Italy and Great Britain in 1992-1993.

By nature, the single currency eliminates any possibility of foreign exchange adjustment for a country taken individually, which risks making everything more rigid. Thus, the only way for a country going through an asymmetrical crisis to adjust itself is by lowering prices, increasing unemployment or emigration. These are difficult prognoses to accept!

This difficulty, however, can be remedied in three ways. We are in the heart of the current debate on the euro. The first solution consists of only allowing into the circle of countries with the same currency those that already have a very high level of economic integration, and are thus almost structurally in the same economic cycle, which significantly reduces the risk of uneven impact. This is why, before and after the advent of the single currency, the convergence criteria are important. This is the position of Germany in particular, which strongly holds to these criteria, even after changing over to the euro.

From this point of view, it develops a perfectly logical argument. But the passage is narrow since it only allows few countries (mainly those of the mark zone, including France) to join this circle. This is the origin of the open question about the southern countries, particularly Italy in recent months.

In addition, the Maastricht criteria, as defined for some of them, have not been adapted to cyclical changes. If we wanted to adhere to them at any cost, they would cause the slowdown of the much anticipated boost in growth. Consequently, Germany has thus opted for the following alternative: rigidly doubling down, in accounting terms, on the criteria and taking major risks for growth, or making it a “policy” reading, but no longer having a presentable argument to put before southern Europe to persuade it to wait. This is part of the current pressure in Germany to push back the date of changing over to the euro.

The two other solutions do not eliminate the need for a convergence, a priori and a posteriori, to reduce the risks of uneven impacts, even if it means re-examining the criteria. However they are not happy with that. The second solution is thus based on a stronger idea of what the countries having adopted the euro can share. It consists of coordinating economic policies through appropriate bodies such as a “Council for stability and growth”.

On the one hand, this coordination would enable implementing a stimulus policy in an articulated and complementary manner, and a policy for austerity, according to the cyclical phases, on the other hand, thus playing the “win-win” game and not the game of “every man for himself” which most often makes all players lose.

The third solution is no doubt the best economically, the most logical and the only one to complete the construction of Europe, both monetarily and politically. Let us remember that a centralised monetary power has always been accompanied by a similar movement on a political level. Only greater political integration, leading to a greater degree of federalism, can structurally reduce the dangers of a lack of flexibility engendered by the common currency. Then only, as in the United States of America, for example, an economic crisis in one state can be absorbed without the play of relative price movements and employment adjustments alone. A community-level decision-making centre equipped with some tools and expertise, acting only in the principle of subsidiarity, is necessary to institutionalise the Member States’ obligation to cooperate. Federalism allows the coexistence of decentralised state powers and a regulating and coordinating power in the centre.

A federal budget worthy of this name, that does not add to national budgets, would in fact allow transfers of revenues to the affected State and would thus facilitate the necessary adjustments, making them less dramatic and more tolerable. This would not at all exclude the community rules which aim to make each country adhere to minimum “economic wisdom” criteria. This higher degree of federalism should also allow instituting European tax and social minimums. Let us not be fooled; this risk of a race to the bottom – fiscally or socially, so to speak – is one of the major causes that could hinder the construction of Europe.

As far as the euro is concerned, to continue to think like novices that an economically unified Europe will automatically lead to a politically unified Europe is perhaps already a historical error that risks bringing the construction of Europe to a halt.
