The global crisis has left many calling for early warning systems to prompt authorities into action before it’s too late. This column argues that such a system is restricted by our understanding of what caused the crisis in the first place. Indeed, it shows that popular explanations for the current crisis have little to no ability to predict past crises.

Can “early warning indicators” predict which countries are most vulnerable to a crisis? This column argues that, contrary to findings released last year, early warning indicators were useful in identifying which nations were hit hardest by the Global Crisis from 2008 to 2009. The authors argue that the level of central bank reserves was particularly useful. Other useful early warning indicators include real effective exchange rate overvaluation, current accounts, and national savings.

The 2008 global financial crisis has led to renewed calls for “early warning models” to reduce the risks of future crises. But this column says that few of the characteristics suggested as potential causes of the crisis actually help predict the intensity and severity of the crisis across countries. That bodes poorly for the performance of future early warning models.
