On September 11, the KOSPI traded in the early morning session at the 6,800 level. The KOSDAQ also started lower, affected by the weakness in the U.S. stock market and overall macroeconomic uncertainty.

Amid rising tensions in the Middle East and international oil prices surpassing $100 again, which is also impacting the domestic stock market, employees are monitoring the stock market, exchange rates, and oil prices at the dealing room of Hana Bank's head office in Jung-gu, Seoul on the 11th. On that day, the KOSPI opened at 6,802.50, down 231.42 points (3.29%) from the previous session, and the KOSDAQ started at 816.91, down 20.01 points (2.39%), with the declines gradually narrowing. 2026.9.11 Photo by Jo Yongjun

Previously on September 10 (local time), the New York stock market weakened as oil prices and U.S. Treasury yields surged. This led to projections that the domestic market would also start lower. Ji-Young Han, a researcher at Kiwoom Securities, commented, "On September 11, the domestic stock market is expected to open lower due to the pressure of rising interest rates and oil prices, the growing sense of caution regarding the U.S. CPI for August, and increased macroeconomic uncertainties, as well as the KOSPI night futures showing declines in the 3% range."
