History

Historical Context

The 1997 Asian financial crisis forced South Korea to accept a $58.4 billion IMF rescue, devaluing the won past 1,700 per dollar and halving the KOSPI in 1998. Decades of chaebol over-borrowing and reforms that raised foreign-ownership limits still shape policy. In August 2024 the KOSPI jumped 6% as Samsung pledged a 100-trillion-won return and the Treasury launched $4 billion of buybacks.
