South Korean equities fell on Sept. 1 as renewed U.S.-Iran hostilities around the Strait of Hormuz lifted oil prices and U.S. Treasury yields, reviving inflation and Federal Reserve tightening concerns. The KOSPI was down 0.46% at 6,788.51 at 9:28 a.m. after opening 0.52% lower and briefly falling 1.28%, while the KOSDAQ fell 1.07% to 825.36. Foreign investors and institutions sold ₩250.8 billion and ₩294.5 billion in KOSPI shares, while retail investors and Other Corporations bought ₩437 billion and ₩107.8 billion. Strong trade data provided support: South Korea’s August exports rose 68.7% year on year to a record $98.25 billion, extending growth to 15 consecutive months, while semiconductor exports surged 209% to a record $46.65 billion. U.S. chip-stock gains and corporate buying also helped limit losses, although analysts warned that higher yields and oil prices could pressure equities.
