Thailand’s currency devaluation helped trigger the 1997 Asian financial crisis and widespread regional stock-market turmoil.
On July 2, 1997, Thailand abandoned its exchange-rate peg to the U.S. dollar and allowed the baht to float. The currency then lost substantial value, exposing weaknesses in Thailand’s heavily indebted financial and property sectors. Investors became concerned that other economies had similar vulnerabilities.
The pressure spread through Southeast and East Asia. Indonesia’s rupiah and South Korea’s won came under severe strain, while stock markets across the region suffered major declines. International lenders and governments organized rescue packages, including a large International Monetary Fund program for South Korea.
The crisis is sometimes described as a purely currency crisis, but it also caused banking failures, corporate defaults, recessions, and stock-market collapses. Thailand was the initial flashpoint; Indonesia, Malaysia, South Korea, and other economies experienced different versions of the broader shock.
