The 1997 Asian financial crisis gripped much of East and Southeast Asia during the late 1990s. The crisis began in Thailand in July 1997 before spreading to several other countries with a ripple effect, raising fears of a worldwide economic meltdown due to financial contagion. However, the recovery in 1998–1999 was rapid, and worries of a meltdown quickly subsided.
Originating in Thailand, where it was known as the Tom Yum Kung crisis (Thai: วิกฤตต้มยำกุ้ง) on 2 July, it followed the financial collapse of the Thai baht after the Thai government was forced to float the baht due to lack of foreign currency to support its currency peg to the U.S. dollar. Capital flight ensued almost immediately, beginning an international chain reaction. At the time, Thailand had acquired a burden of foreign debt. As the crisis spread, other Southeast Asian countries and later Japan and South Korea saw slumping currencies, devalued stock markets and other asset prices, and a precipitous rise in private debt. Foreign debt-to-GDP ratios rose from 100% to 167% in the four large Association of Southeast Asian Nations (ASEAN) economies in 1993–1996, then shot up beyond 180% during the worst of the crisis. In South Korea, the ratios rose from 13% to 21% and then as high as 40%, while the other northern newly industrialized countries fared much better. Only in Thailand and South Korea did debt service-to-exports ratios rise.
