The benchmark KOSPI climbed 2.25% to close at 9,064 on Thursday, extending gains to fresh record highs, as strong momentum in AI-related semiconductor stocks continued to support the market. SK Hynix advanced 7.22% after announcing the shipment of samples of its next-generation 12-layer HBM4E memory chips to key customers, reinforcing optimism about AI-driven demand, while Samsung Electronics (4.62%) and SK Square (8.65%) also jumped. Investor sentiment remained resilient despite a hawkish signal from the Federal Reserve, which kept interest rates unchanged but indicated that policymakers expect a higher rate path than previously projected. At the same time, easing concerns over energy supplies and geopolitical risks following the US-Iran peace agreement helped sustain risk appetite, with South Korean authorities noting that improving conditions could help stabilize global energy markets and reduce uncertainty facing the export-driven economy.
