Vulnerability to a Currency Crisis: Lessons from the Asian Experience

Are currency crises caused by manias and panics in financial markets, or by unsustainable deteriorations in domestic macroeconomic conditions? This question is explored in the context of the recent Asian currency crisis. The theoretical concept of vulnerability is used to identify three early‐warning indicators of susceptibility to a currency crisis: rapid accumulation of mobile capital; domestic lending booms; and overvalued exchange rates. It is shown that the crisis and noncrisis countries of Asia may be distinguished empirically, using these indicators, over the decade preceding the crisis. This exercise provides convincing evidence that the crisis emanated largely from domestic macroeconomic conditions.
