Overshootings and Reversals: The Role of Monetary Policy


  • Ilan Goldfajn
  • Poonam Gupta


This paper provides evidence on the relationship between monetary policy and the exchange rate in the aftermath of currency crises taking into account the role of a fragile banking system. It analyzes a large set of currency crises that led to real exchange rate undervaluations from a sample of 80 countries in the period 1980 to 1998. First, the paper evaluates whether tight monetary policy increases substantially the probability of reversing the undervaluation through nominal appreciation of the exchange rate rather than through higher inflation. Second, using panel data, the paper estimates the relationship between real exchange rates and real interest rates. We find that tight monetary policy facilitates the reversal of the real exchange rate through nominal appreciation rather than inflation. In contrast, when the economy is also facing a banking crisis, tight monetary policy may not have the same effect.
