What history tells us about the aftermath of a financial crisis

The Reinhart couple sounds the alarming bell (article from FT):

The landscape of Jackson Hole, Wyoming, where central bankers gathered at their annual conference last week, is spectacular and forbidding. Jagged peaks and vast empty spaces stretch across the horizon. For the attendees, however, it was both a vista and a metaphor. Having lived through a precipitous global economic drop, they now must forecast how steep or flat will be the incline of recovery.

Ben Bernanke, chairman of the Federal Reserve, painted a sober but reassuring picture of US prospects. The basis for sustained recovery is in place, and canny Fed officials are now alive to the dangers of both deflation and inflation. Similarly Jean Claude Trichet, head of the European Central Bank, spoke about how the dust had begun to settle on the crisis. Policymakers and financial markets seem to be looking at what comes next.

We have analysed data on numerous severe economic dislocations over the past three-quarters of a century; a record of misfortune including 15 severe post-second world war crises, the Great Depression and the 1973-74 oil shock. The result is a bracing warning that the future is likely to bring only hard choices.

Our research found real per capita gross domestic product growth tends to be much lower during the decade following crises. Unemployment rates are higher, with the most extreme increases in the most advanced economies that experienced a crisis. In 10 of the 15 episodes we studied, unemployment never fell back to its pre-crisis level, not in the following decade nor right up to the end of 2009.

It gets worse. Where house price data are available, 90 per cent of the observations over the decade after a crisis are below their level the year before the crisis. Median prices are 15 to 20 per cent lower too, with cumulative declines as large as 55 per cent. Credit is also a problem. It expands rapidly before crises, but post-crash the ratio of credit to GDP declines by an amount comparable to the pre-crisis surge. However, this deleveraging is often delayed and protracted.

Our review of the historical record, therefore, strongly supports the view that large destabilising economic events produce big changes in long-term indicators, well after the upheaval of the crisis. Up to now we have been traversing the tracks of prior crises. But if we continue as others have before, the need to deleverage will dampen employment and growth for some time to come.
