KOSPI Index Rebounds as Trump Calls for Iran-Israel Pause

South Korea's benchmark KOSPI index rebounded on June 9, 2026, recovering to the 8,000-point range after experiencing a record single-day gain of over 8%. The surge followed a sharp decline on Monday caused by military strikes between Iran and Israel. The recovery aligned with a broader trend in U.S. and Asian markets after Donald Trump appealed for a pause in the conflict.

The rebound was fueled by net purchases from institutional investors and a significant rally in semiconductor heavyweights. SK Hynix shares zoomed 12%, while Samsung Electronics shares rose 7.61%. The extreme volatility during the session prompted the Korea Exchange to activate its buy-side sidecar mechanism to stabilize trading.

Reports on the final closing value vary slightly. One source states the KOSPI closed at 8,096.93 with a gain of 612.52 points, while Bloomberg data indicates a gain of 574 points, closing at 8,059.
