South Korea's KOSPI fell in early trading on August 11 after a softer Wall Street session, weakness in U.S. and domestic semiconductor shares, higher oil prices and rising U.S. Treasury yields dented risk appetite. The benchmark opened at 6,240.06, down 59.60 points, or 0.95%, and was quoted at 6,241.8 at 9:15 a.m., down 57.86 points, or 0.92%, and at 6,242.28 at 10:05 a.m., down 57.38 points, or 0.91%, after trimming an earlier drop of more than 1%. The move came as doubts over reopening the Strait of Hormuz lifted West Texas Intermediate crude 5.1% to $82.13 a barrel and pushed the U.S. 10-year Treasury yield above 4.7% ahead of U.S. July CPI data. In Seoul, SK hynix and other chip-related names fell while Samsung Biologics rose. Investor flows shifted through the morning: foreigners remained net buyers, institutions were net sellers, and by 10:05 a.m. individuals had turned into strong net buyers. Analysts described the decline as a corrective phase after the previous session's rally, while noting possible support from U.S. tech earnings and expectations for shareholder returns from domestic chip stocks.
