South Korean KOSPI Index Drops 11 Percent Over Two Days

The Korea Composite Stock Price Index (KOSPI) declined for two consecutive trading sessions, losing more than 750 points, or 11 percent of its value. The downturn began on July 20, 2026, when the KOSPI opened 2.60% lower and eventually tumbled 304.33 points, or 4.46 percent, to close at 6,516.27. Technology and financial shares suffered the most significant losses during this period.

Parallel declines occurred in the tech-heavy KOSDAQ index, which opened July 20 down 2.35% at 773.21. This volatility coincided with a broader slump on Wall Street, where the Dow, NASDAQ, and S&P 500 all closed lower.

Market instability is attributed to concerns over interest rate outlooks and an escalating conflict between the United States and Iran, which drove a surge in treasury yields and pushed crude oil prices higher. Additionally, The Conference Board Europe reported a modest decline in leading U.S. economic indicators for June. Analysts suggest the market may see a technical rebound due to bargain hunting.
