The sharp decline in South Korean stocks reflects heightened risk aversion driven by tech sector weakness and geopolitical tensions. The KOSPI's drop may weigh on investor sentiment across Asian markets, while safe-haven assets like the U.S. dollar could strengthen.

Event Summary

On July 28, 2026, South Korean stocks opened sharply lower, with the KOSPI falling over 5% in early trading, triggering a sell-side sidecar by the Korea Exchange. The decline was led by tech and semiconductor shares, following a selloff on Wall Street amid renewed skepticism over AI spending and escalating Middle East tensions after the United States launched fresh strikes on Iran. Samsung Electronics and SK Hynix fell sharply, while defense and shipping stocks saw gains. The Korean won weakened against the U.S. dollar. U.S. President Donald Trump indicated ongoing talks with Iran and a potential deal.
