Black Tuesday in Japanese and Korean Stock Markets: South Korea Triggers Circuit Breaker, Nikkei Plummets, AI Boom Undergoes Phased Adjustment
"Black Tuesday" for Asian Markets: Korean Stocks Halted by Circuit Breaker, Nikkei Plunges as AI Rally Undergoes Correction
Asian stock markets experienced severe turbulence on Tuesday, with South Korea's benchmark KOSPI index plummeting nearly 10% after triggering a market-wide trading halt when its losses exceeded 8%. Japan's Nikkei 225 index also fell sharply by approximately 3.5%, ending an eight-day winning streak. The sell-off was heavily concentrated in the technology and semiconductor sectors, with giants like Samsung Electronics and SK Hynix leading the declines. The plunge reflected a rapid reversal from recent highs, with the KOSPI having retreated over 12% from its mid-June peak.
Analysts attribute the sharp correction to multiple converging factors. The direct trigger was weakness in U.S. tech stocks, which fueled profit-taking in overbought Asian markets. Furthermore, stronger-than-expected U.S. jobs data has reinforced expectations that the Federal Reserve will maintain or even raise interest rates, putting pressure on rate-sensitive growth stocks. Structural vulnerabilities also played a role, particularly in South Korea, where the market is highly concentrated in a few semiconductor heavyweights, making it susceptible to shifts in global AI demand and foreign capital outflows.
Despite the short-term volatility, the long-term narrative for AI and semiconductors remains intact. Industry forecasts still point to massive growth in global AI capital expenditure over the coming years. South Korean firms like SK Hynix maintain a dominant position in critical segments like High Bandwidth Memory (HBM), with long-term orders secured well into 2027. While near-term fluctuations are expected to continue, driven by U.S. monetary policy signals and upcoming corporate earnings, the current correction may present a buying opportunity for quality assets tied to the enduring AI infrastructure build-out.
