History

Historical Context

July 1997’s Asian financial crisis forced South Korea to take a $58.4 billion IMF bailout after the won slipped past 1,700 per dollar and foreign investors withdrew about $30 billion. The KOSPI fell roughly 50%, 787 insolvent banks were closed, and regulators added 20-minute circuit-breaker halts and raised the foreign-ownership limit to 100%. Today’s 7.6% KOSPI drop and sell-off in Samsung and SK Hynix mirror those shocks.
