Abstract: This paper attempts to identify whether the recent foreign reserve accumulation in Asian economies has been too extraordinary to recover the moderate level of reserves which depleted at the time of the currency crisis in 1997-1998. First of all, the level of reserves numerated by various economic fundamentals such as broad money, imports and short-term external debt in Asian economies was examined in order to judge whether the level was high enough to weather speculative pressures at the onset of the crisis in 1997. The analysis is based on a Brownian motion model with an absorbing barrier. Although most Asian economies appeared to have larger reserves (reserve indicators) than the estimated threshold at the time of the crisis of 1997, reserves in terms of short-term external debt were apparently not sufficient to avoid speculative attacks. Then, based on the estimated threshold of reserve indicators, the likelihood of a 25% devaluation within three months ahead is calculated. Probabilities of currency devaluation vary from time to time, among countries, and among reserve indicators. The devaluation likelihood was modest in the mid 1990s, but then it showed a big jump in 1997 in Indonesia, Thailand, Korea, and Philippines.
