South Korea’s KOSPI stood at 6,647.45 at 9:16 a.m. on the 15th, down 36.92 points, or 0.55%, after recovering from a deeper early-session decline. The index opened 0.38% lower at 6,659.25, fell to 6,625.15 and then traded between 6,640 and 6,670. Retail investors bought a net 343.6 billion won, while foreign and institutional investors sold 212.1 billion won and 177.1 billion won, respectively. Program trading recorded net sales of 140.5 billion won. The market faced pressure from a U.S. 10-year Treasury yield above 5%, a sharp sell-off in semiconductor shares and concerns about slower artificial intelligence development. The Dow, Nasdaq and S&P 500 fell 0.29%, 0.56% and 0.48%, respectively, while the Philadelphia Semiconductor Index plunged 5.9%. Micron fell 5.2% and Nvidia declined 3.4%. The September FOMC (Federal Open Market Committee) meeting on the 15th–16th is the next major market event, with the CME FedWatch Tool showing an approximately 86% probability of a 0.25 percentage point rate increase. Analysts are focused on the Federal Reserve’s dot plot, Chair Jerome Powell’s press conference, the stability of 10-year yields below 5% and whether foreign selling eases.
