KOSPI drops 7% and Nikkei falls 3.5% as U.S. inflation revives rate‑hike fears
South Korea’s KOSPI index has plunged 7%, while Japan’s Nikkei is down 3.5%, after U.S. inflation data reignited expectations of more Federal Reserve rate hikes. The sell‑off has hit AI‑linked and technology stocks especially hard and is testing how much volatility Asian markets can absorb.
A sharp sell‑off in Asian equities has underscored how sensitive regional markets remain to U.S. economic data. South Korea’s KOSPI has fallen 7%, and Japan’s Nikkei is down 3.5%, after U.S. inflation figures renewed worries that the Federal Reserve could keep raising interest rates.
The KOSPI’s 7% decline reflects a rapid shift in how investors are valuing major South Korean companies across the index. In Tokyo, the Nikkei’s 3.5% slide has been led by companies tied to artificial intelligence and broader technology themes, as investors move money out of some of the market’s most favored stocks. Reporting links both moves to the latest U.S. inflation release and to growing concern that interest rates in the United States may stay high or rise further.
For Korean savers and funds with heavy exposure to domestic equities, these moves translate into large one‑day hits to portfolios and retirement plans. Investors who concentrated in chipmakers and other companies associated with AI trends now face a sudden reversal in sectors that have been central to South Korea’s growth ambitions.
In Japan, the drop in technology and AI‑related shares complicates the efforts of policymakers who have been hoping to present Tokyo as a stable base for high‑growth companies as global supply chains adjust. A market led down by some of its most dynamic companies raises questions about how resilient that strategy is to shifts in global interest‑rate expectations.
The cross‑border nature of the sell‑off highlights how strongly Asian markets still track U.S. monetary policy. Higher or longer‑lasting U.S. rates tend to draw capital toward dollar assets, weaken regional currencies, and push up borrowing costs across export‑dependent economies such as South Korea and Japan.
The turbulence also influences how company leaders in both countries think about investment, acquisitions, and research spending in sensitive sectors such as semiconductors. Sharp falls in share prices can make it harder to raise capital and may delay or scale down projects that governments see as important for economic or security reasons.
AI‑related and semiconductor stocks, which have become core to national industrial strategies, have shown that they behave like other risk assets when macroeconomic conditions change. Their valuations can swing quickly in response to data releases and shifts in expectations for central bank policy.
Investors will now be watching to see whether South Korean and Japanese officials comment on the market moves or adjust their language on monetary and fiscal policy, and whether selling pressure continues in coming sessions, particularly in financial and export‑oriented stocks. A deeper and more prolonged slide would signal that markets are reassessing Asia’s exposure to U.S. interest‑rate risk rather than reacting to a single data point.
