The collapse of the Thai baht triggered Thailand’s role in the 1997 Asian financial crisis and regional market crash.
Thailand had maintained a de facto peg linking the baht to the U.S. dollar. Heavy borrowing, property speculation, weak financial institutions, and pressure from currency speculators made that arrangement increasingly difficult to defend. On July 2, 1997, Thailand allowed the baht to float after spending foreign-exchange reserves to support it.
The baht then lost substantial value, raising the local-currency cost of dollar-denominated debt. Financial stress spread through banks, companies, and property markets. Investors reassessed other economies with similar vulnerabilities, leading to pressure on currencies and stock markets in Indonesia, South Korea, Malaysia, and elsewhere.
The crisis was not caused by one factor alone. Fixed or tightly managed exchange rates, short-term foreign borrowing, weak regulation, and excessive credit all mattered. The International Monetary Fund arranged assistance programs for several affected economies, while the crisis later contributed to major political and economic changes in the region.
