South Korean Stocks Plunge as Iran Conflict Erupts, Reversing 2025 Gains

Key Facts

1South Korean stocks plunged as the Iran war broke out.

2The South Korean market was the world's hottest of 2025 prior to the plunge.

South Korean equities experienced a significant sell-off today following the sudden outbreak of war in Iran. The geopolitical conflict triggered massive risk-off sentiment across global markets, hitting the high-performing Korean sector particularly hard. Prior to this plunge, the South Korean stock market had been recognized as the world's top-performing market of 2025. The sharp reversal saw major indices like the KOSPI lose substantial ground as investors fled to safe-haven assets. Market participants are now closely monitoring the impact on the USD/KRW exchange rate and broader regional stability. Analysts warn that continued volatility is likely as long as the military escalation in the Middle East persists.
