Southern Eurozone countries have been forced to introduce severe austerity programs since 2011. Where did the forces that led these countries into austerity come from? Are these forces the result of deteriorating economic fundamentals that made austerity inevitable? Or could it be that the austerity dynamics were forced by fear and panic that erupted in the financial markets and then gripped policymakers. Furthermore, what are the implications of these severe austerity programs for the countries involved?
The facts: Austerity and spreads
There is a strong perception that countries that introduced austerity programs in the Eurozone were somehow forced to do so by the financial markets. Is this perception based on a reality? Figure 1 shows the average interest rate spreads in 2011 on the horizontal axis and the intensity of austerity measures introduced during 2011 as measured by the Financial Times on the vertical axis. It is striking to find a very strong positive correlation. The higher the spreads1 in 2011 the more intense were the austerity measures. The intensity of the spreads can be explained almost uniquely by the size of the spreads (the R-squared is 0.97). Note the two extremes. Greece was confronted with extremely high spreads in 2011 and applied the most severe austerity measures amounting to more than 10% of GDP per capita. Germany did not face any pressure from spreads and did not do any austerity.

There can be little doubt. Financial markets exerted different degrees of pressure on countries. By raising the spreads they forced some countries to engage in severe austerity programs. Other countries did not experience increases in spreads and as a result did not feel much urge to apply the austerity medicine.
Two theories about spreads
The next question that arises is whether the judgement of the market (measured by the spreads) about how much austerity each country should apply was the correct one. There are essentially two theories that can be invoked to answer this question. According to the first theory, the surging spreads observed from 2010 to the middle of 2012 were the result of deteriorating fundamentals (e.g. domestic government debt, external debt, competitiveness, etc.). Thus, the market was just a messenger of bad news. Its judgement should then be respected. The implication of that theory is that the only way these spreads can go down is by improving the fundamentals, mainly by austerity programs aimed at reducing government budget deficits and debts.
Another theory, while accepting that fundamentals matter, recognises that collective movements of fear and panic can have dramatic effects on spreads. These movements can drive the spreads away from underlying fundamentals, very much like in the stock markets prices can be gripped by a bubble pushing them far away from underlying fundamentals. The implication of that theory is that while fundamentals cannot be ignored, there is a special role for the central bank that has to provide liquidity in times of market panic (De Grauwe 2011).
The decision by the ECB in 2012 to commit itself to unlimited support of the government bond markets was a game changer in the Eurozone. It had dramatic effects. By taking away the intense existential fears that the collapse of the Eurozone was imminent the ECB’s lender of last resort commitment pacified government bond markets and led to a strong decline in the spreads of the Eurozone countries.
This decision of the ECB provides us with an interesting experiment to test these two theories about how spreads are formed. Figure 2 provides the evidence. On the vertical axis we show the change in the spreads in the Eurozone from the middle of 2012 (when the ECB announced its program) to the beginning of 2013. On the horizontal axis we present the initial spread, i.e. the one prevailing in the middle of 2012. We find a surprising phenomenon. The initial spread (i.e. in 2012Q2) explains almost all the subsequent variation in the spreads. Thus the country with the largest initial spread (Greece) experienced the largest subsequent decline; the country with the second largest initial spread (Portugal) experienced the second largest subsequent decline, etc. In fact the points lie almost exactly on a straight line going through the origin. The regression equation indicates that 97% of the variation in the spreads is accounted for by the initial spread. Thus it appears that the only variable that matters to explain the size of the decline in the spreads since the ECB announced its determination to be the lender of last resort is the initial level of the spread. Countries whose spread had climbed the most prior to the ECB announcement experienced the strongest decline in their spreads – a remarkable feature.

In previous research (De Grauwe and Ji 2012) we provided evidence that prior to the regime shift made possible by the ECB a large part of the surges in the spreads were the results of market sentiments of fear and panic that had driven the spreads away from their underlying fundamentals. Figure 2 tends to confirm this. By taking away the fear factor the ECB allowed the spreads to decline. We find that the decline in the spreads was the strongest in the countries where the fear factor had been the strongest.
What about the role of fundamentals in explaining the decline in the spreads observed since the middle of 2012? Figure 3 provides the evidence. We selected the change in the government debt-to-GDP ratio as the fundamental variable as suggested by many studies (Aizenman and Hutchinson 2012, Attinasi, et al., 2009, Beirne and Fratscher 2012, De Grauwe and Ji 2012). We observe two interesting phenomena in Figure 3. First, while the spreads declined, the debt-to-GDP ratio continued to increase in all countries after the ECB announcement. Second, the change in the debt-to-GDP ratio is a poor predictor of the declines in the spreads. Thus the decline in the spreads observed since the ECB announcement appears to be unrelated to the changes of the debt-to-GDP ratios. If anything, the fundamentalist school of thinking would have predicted that as the debt-to-GDP ratios increased in all countries, spreads should have increased rather than decline.

From the previous discussion one can conclude that a large component of the movements of the spreads since 2010 was driven by market sentiments. These market sentiments of fear and panic first drove the spreads away from their fundamentals. Later as the market sentiments improved thanks to the announcement of the ECB, these spreads declined spectacularly. This was predicted in De Grauwe (2011), Wolf (2011) and Wyplosz (2011).
We can now give the following interpretation of how the spreads exerted their influence on policymakers and led them to apply severe austerity measures. As the spreads increased due to market panic, these increases also gripped policymakers. Panic in the financial markets led to panic in the world of policymakers in Europe. As a result of this panic, rapid and intense austerity measures were imposed on countries experiencing these increases in spreads. The imposition of dramatic austerity measures was also forced by the fact that countries with high spreads were pushed into a liquidity crisis by the same market forces that produced the high spreads (De Grauwe 2011). This forced these countries to beg 'cap in hand' for funding from the creditor countries.
The effects of panic-driven austerity
How well did this panic-induced austerity work? We provide some answers in Figures 4 and 5. Figure 4 shows the relation between the austerity measures introduced in 2011 and the growth of GDP over 2011-12. We find a strong negative correlation. Countries that imposed the strongest austerity measures also experienced the strongest declines in their GDP. This result is in line with the IMF’s recent analysis (IMF 2012).

Some will say that this is the price that has to be paid for restoring budgetary orthodoxy. But is this so? Figure 5 may lead us to doubt this. It shows the austerity measures and the subsequent change in the debt-to-GDP ratios. It is striking to find a strong positive correlation. The more intense the austerity, the larger is the subsequent increase in the debt-to-GDP ratios. This is not really surprising, as we have learned from the previous figure, that those countries that applied the strongest austerity also saw their GDP (the denominator in the debt ratio) decline most forcefully. Thus, it can be concluded that the sharp austerity measures that were imposed by market and policymakers’ panic not only produced deep recessions in the countries
