The good news from our historical study of eight centuries of international financial crises is that, so far, they have all ended. And we confidently predict this one will end, too. We are just not quite so sure it will be nearly as soon as the chirpy forecasts coming from policymakers around the globe. The U.S. administration, for example, is now predicting that growth will renew in the latter part of this year and continue at a brisk pace of 4 percent for several years thereafter. Is this a fact-based forecast or wishful thinking?
A careful look at the international evidence on severe banking crises suggests a far more cautious assessment. The recessions that follow in the wake of big financial crises tend to last far longer than normal downturns, and to cause considerably more damage. If the United States follows the norm of recent crises, as it has until now, output may take four years to return to its pre-crisis level. Unemployment will continue to rise for three more years, reaching 11”“12 percent in 2011.
