South Korean Stocks Fall To Two-Week Low

South Korean shares plunged more than 6% on Monday, March 23, 2026, with the KOSPI falling 375.45 points to 5,405.75, its lowest close since March 9. The won weakened to 1,517.3 per dollar, a 17-year low, as heightened Iran-U.S. tensions and threats against Gulf energy facilities prompted heavy foreign selling and triggered trading curbs. Market volatility pushed the 10-year yield up to 3.880%.
