We find that declining bank credit to the private sector will not necessarily constrain the economic recovery after output has bottomed out following a financial crisis. To obtain this result, we examine data from 39 financial crises, which - as the current one - were preceded by credit booms. In these crises the change in bank credit, either in real terms or relative to GDP, consistently did not correlate with growth during the first two years of the recovery. In the third and fourth year, the correlation becomes statistically significant but remains small in economic terms. The lack of association between deleveraging and the speed of recovery does not seem to arise due to limited data. In fact, our data shows that increasing competitiveness, via exchange rate depreciations, is statistically and economically significantly associated with faster recoveries. Our results contradict the current consensus that private sector deleveraging is necessarily harmful for growth.

Conclusion
We find that bank lending to the private sector and economic growth are essentially uncorrelated after those financial crises that were preceded by credit booms. This result is relevant for the major advanced economies recovering from the financial crisis, since the current crisis was also preceded by a credit boom. Our results suggest that the ongoing deleveraging in advanced economies might not be as harmful for the recovery as many fear.

We also find that depreciating real exchange rates are statistically and economically significantly associated with substantially stronger economic growth.  This finding on real exchange rates shows that the price channel for external adjustment can contribute to stronger economic activities. Consequently, if crisis hit countries can generate substantial real effective exchange rate depreciation, either via nominal exchange rate depreciation or internal cost adjustments, this could hasten their recovery. However, given the global nature of the current crisis this solution might not be available for all countries at the same time.

Furthermore, we find some weak negative association between public debt ratios and recoveries: increasing public debt seems to lead to somewhat weaker recoveries. This might cast doubt on the claims that fiscal stimulus is the appropriate answer to fasten the recovery now.

While we are aware that these results come with caveats, we believe that our results provide a useful contribution to the creditless recovery literature. We hope that these finding would elicit debates and further research to understand debt dynamics, financial crises and how recoveries work.
