The Asian financial crisis was a period of financial crisis that gripped much of East Asia beginning in July 1997 and raised fears of a worldwide economic meltdown due to financial contagion.
The crisis started in Thailand (known in Thailand as the Tom Yum Goong crisis; Thai: วิกฤตต้มยำกุ้ง) with 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. At the time, Thailand had acquired a burden of foreign debt that made the country effectively bankrupt even before the collapse of its currency. As the crisis spread, most of Southeast Asia and Japan saw slumping currencies, devalued stock markets and other asset prices, and a precipitous rise in private debt.
Indonesia, South Korea, and Thailand were the countries most affected by the crisis. Hong Kong, Laos, Malaysia and the Philippines were also hurt by the slump. Brunei, China, Singapore, Taiwan, and Vietnam were less affected, although all suffered from a loss of demand and confidence throughout the region. Japan was also affected, though less significantly.
