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.

South Korean Shares Pause Four-Day Rally
The benchmark KOSPI edged down to around 8,710 on Wednesday, pausing a four-day rally, as weakness in global technology stocks and caution ahead of the Federal Reserve's policy decision weighed on sentiment. Semiconductor shares came under pressure after a selloff in US AI-related stocks, with market heavyweight Samsung Electronics declining and weighing on the broader index. Losses were also seen in Hyundai Motor (-3.9%), Kia Corporation (-2.2%), Hyundai Mobis (-4.1%), and KB Financial Group (-1.7%). Investors also remained wary ahead of the first Federal Open Market Committee meeting under Fed Chair Kevin Warsh, amid concerns that policymakers could signal a more hawkish stance despite expectations that interest rates would remain unchanged. Meanwhile, easing tensions in the Middle East and receding oil-price pressures supported risk appetite and helped limit losses.
