The benchmark KOSPI jumped more than 3% to around 5,840 on Wednesday, its highest level in two weeks, fueled by strong gains in technology stocks. Leading semiconductor giants Samsung Electronics (up 5.6%) and SK hynix (up 4.0%) rallied on renewed optimism about artificial intelligence demand, following Nvidia’s GTC conference, where Korean chipmakers were spotlighted as key partners in next-generation AI systems. Other notable gainers included Hyundai Motor (3.8%), LG Energy Solution (1.6%), SK Square (5.8%), and Kia (3.8%).
At the same time, investors remained cautious over escalating tensions in the Middle East, as attacks on energy infrastructure intensified supply concerns. Although oil prices have eased recently, volatility in the energy market continues to pose a risk for South Korea’s import-dependent economy. The Korean won also strengthened as the US dollar weakened ahead of the Federal Reserve’s policy decision, with interest rates widely expected to remain on hold, providing additional support to market sentiment.
