The Asian Financial Crisis (1997)

The Asian Financial Crisis of 1997 was the most devastating emerging-market collapse of the 1990s, wiping out 70-80% of stock values across Thailand, South Korea, Indonesia, and Malaysia. Triggered by the Thai baht's devaluation, it forced IMF bailouts with harsh austerity conditions, pushing millions back into poverty. This crisis outperforms #8's European Sovereign Debt Crisis in speed of contagion, spreading from one currency to a continent in weeks. With regional GDP contracting by 13% in Indonesia alone, it remains the benchmark for how a currency crisis can destabilize entire economies faster than the typical financial shock.
