South Korean shares slide as AI sector concerns, Fed rate stance hit chipmakers
South Korean shares fell on Thursday as concerns about the artificial intelligence sector and global inflation weighed on the chip-heavy market. The decline was part of a broader drop in Asian equities, with bonds rallying on signs of cooling inflation.
The KOSPI index, which includes major chipmakers Samsung Electronics and SK Hynix, has been particularly volatile. In June, the index triggered market-wide circuit breakers three times, including a 10% fall on June 23 where SK Hynix dropped 12.5%, its steepest session since 2008.
The U.S. Federal Reserve maintained a hawkish stance on interest rates at its June meeting, holding rates at 3.50-3.75% but projecting further hikes this year. The committee revised its 2026 inflation projection up sharply, contributing to market volatility.
The artificial intelligence sector has seen a shift from software and compute to memory hardware, with companies like Micron reporting strong gains. However, concerns about the longevity of the AI boom and valuation anxieties have weighed on the market.
Meanwhile, the broader global market has seen a rotation from overextended chip stocks to defensive safe havens. The Dow Jones rose 2.4% in June to hit fresh record highs, even as tech dragged the monthly totals for the Nasdaq Composite down 3.2% and the S&P 500 down 1.3%.
