Baht devaluation marked the beginning of the 1997 Asian financial crisis and its ensuing market crashes.
On July 2, 1997, Thailand abandoned its fixed exchange-rate policy and allowed the baht to float after intense pressure from currency speculators and dwindling foreign-exchange reserves. The baht then lost substantial value, undermining companies and banks that had borrowed heavily in foreign currencies.
The crisis spread through financial links and investor confidence. Indonesia, South Korea, Malaysia, and the Philippines were among the economies affected, while their currencies, stock markets, banks, and businesses came under severe pressure. International Monetary Fund rescue programs were arranged for several countries, although the conditions attached to assistance remained controversial.
The episode is often called the Asian financial crisis, but it was not a uniform collapse across every Asian economy. China largely avoided the same currency devaluation cycle, and Japan faced its own long-running banking and asset problems. The crisis exposed the danger of short-term foreign borrowing combined with weak financial regulation and rigid exchange-rate commitments.
