Abstract

In case of speculative attacks, the central banks' decisions to intervene or not to intervene seem to play an important role for the economic costs of currency crises. The central bank can either abstain from intervening or start an intervention, which in turn can be successful or unsuccessful. Therefore, an adequate analysis of the costs of currency crises has to take into account three different types of currency crises: (i) an immediate depreciation without any central bank interventions, (ii) a successful defense, and (iii) an unsuccessful attempt to defend the exchange rate. We find that the decision of the central bank to intervene or to remain passive is risky. If the central bank intervenes and succeeds she can achieve the best growth performance on average. However, if the interventions are not maintained and the currency depreciates the subsequent output loss is particularly severe. Abstaining from an intervention yields a scenario with a relatively small drop in output. Giving in to a speculative attack rather than trying to fight it can thus be a suitable option for a risk-averse central bank.
