The benchmark KOSPI rose more than 1% to around 6,650 on Thursday, recovering from the previous session as stronger Wall Street performance and easing Middle East tensions improved risk sentiment. President Donald Trump said renewed US attacks on Iran would likely be short-lived, while lower oil prices reduced concerns about inflation and energy costs. Samsung Electronics and SK hynix each gained more than 1%, and LG Energy Solution and KB Financial Group were among the strongest performers. Gains were capped by potential US semiconductor tariffs, with Commerce Secretary Howard Lutnick saying the administration was considering a targeted policy linking tariff relief to investment in US chip manufacturing.
