The European Debt Crisis: When Words Move Markets

*A crisis that had persisted for years, resisting enormous sums of money, was turned by a short remark from a central banker who had not yet spent anything.*

Beginning in late 2009, the countries of the eurozone entered a crisis that would persist for several years. It began with the revelation that Greece's fiscal position was substantially worse than had been reported, and it spread from there, as investors began to examine the finances of other member states with a scepticism they had not previously applied. Borrowing costs for several countries rose sharply, and the question of whether the shared currency itself would survive became a serious one.

The mechanism that made the crisis so dangerous is worth understanding carefully, because it is a mechanism that recurs. A country's ability to service its debts depends substantially on the rate of interest it must pay to borrow. If investors believe a country may default, they demand a higher rate to compensate for that risk. But the higher rate makes the debt more expensive to service, which makes default more likely, which justifies an even higher rate. The belief, once established, produces the conditions that vindicate it.

This is a self-fulfilling dynamic, and it has an uncomfortable property: a country can be pushed into default by the expectation of default, even if its underlying finances would have been manageable at ordinary borrowing costs. There is no stable resting point. Once the expectation takes hold, the arithmetic drives it forward, and the country's actual fiscal conduct becomes almost irrelevant to the outcome. Several eurozone countries found themselves in precisely this position.

Enormous efforts were made to contain the crisis through conventional means. Rescue packages were assembled, austerity conditions were imposed, institutions were created to provide funds. These measures were substantial, expensive, and politically excruciating, and for a considerable period they did not work. The borrowing costs of the affected countries continued to rise, contagion spread from smaller economies toward larger ones, and the survival of the currency union came into genuine doubt.

In July 2012, the president of the European Central Bank stated in a speech that the bank would do whatever it took, within its mandate, to preserve the euro, and added that it would be enough. The remark was brief. No money was spent. No programme was launched that day. The commitment was, at that moment, entirely verbal.

The effect was immediate and substantial. Borrowing costs for the countries under pressure began to fall, and the acute phase of the crisis receded. The mechanism was straightforward once the logic of the earlier dynamic is understood. Investors had been demanding high rates because they believed default was possible. If a central bank with effectively unlimited capacity to create currency was genuinely committed to preventing that outcome, then default became far less likely, and the high rates were no longer justified. The expectation reversed, and the arithmetic that had been driving the crisis forward now ran in the other direction.

The remarkable feature is that the commitment largely did not need to be exercised. The programme announced subsequently was, in the event, used far less than had been anticipated. The credibility of the commitment was sufficient to alter expectations, and the alteration of expectations was sufficient to change the outcome. The threat worked because it was believed, and because it was believed it did not have to be carried out.

For an investor, several lessons follow. The first concerns the nature of prices in markets where expectations are self-reinforcing. In such markets, the price is not simply a reflection of underlying conditions; it is a participant in determining them. An investor analysing the fundamentals of a country's finances while ignoring the dynamics of expectation was analysing only half the situation, and the half they ignored was the half that was moving.

The second concerns the danger of predicting political and institutional outcomes, which this episode illustrates painfully. A great many investors positioned themselves during those years on the basis of confident views about whether the currency union would survive, whether particular countries would exit, and what politicians would ultimately do. These questions were not answerable by analysis, because they depended on decisions that had not yet been made by people who had not yet made them. Positioning on such judgements is not investing but forecasting political behaviour, and the record of doing so successfully is poor.

The third and most durable lesson is that the ground on which an analysis rests can change without warning. An investor who had correctly assessed a country's fiscal position in early 2012 held a view that was rendered largely irrelevant by a sentence spoken in July. The facts had not changed. The framework within which those facts were interpreted had, and no amount of diligence about the facts would have anticipated it.

It is worth adding a note about the human cost, because a purely financial account of this episode would be incomplete and somewhat cold. The austerity conditions imposed on several countries during these years produced very substantial hardship, including unemployment at levels that damaged a generation's prospects and reductions in public provision that fell most heavily on those least able to absorb them. Whether those conditions were necessary, proportionate, or effective remains a matter of serious and legitimate disagreement among economists and among the populations who lived through them, and it is not a question an investor is well placed to adjudicate. What can be said is that markets and the people within them are not separable, that the numbers on a screen during those years corresponded to real disruption in real lives, and that an investor who forgets this has understood the arithmetic while missing what the arithmetic was about.

At VESTFY™ the episode is presented as a caution against the confidence that fundamental analysis alone determines outcomes. Fundamentals matter enormously over long periods, which is why patient investing works. But in the shorter term, expectations, institutions, and the credibility of those who make commitments can dominate entirely, and an investor who has staked a position on their own reading of a political situation has left the domain in which their analysis has any advantage at all.
