Kospi Drops 8.1% and Nikkei 4.9% Amid Inflation and AI Debt Concerns
Kospi 200 dropped 8.1% to a six-month low as circuit breakers were triggered, Nikkei lost 4.9%, and CSI 300 declined, following US inflation reaching 3.7%.

Asian stock markets suffered sharp losses following higher-than-expected US inflation data, with South Korea's Kospi 200 index falling 8.1% to its lowest close in six months, triggering circuit breakers, according to The Guardian.
Japan's Nikkei 225 index lost 4.9%, and China's CSI 300 index fell by up to 2.4%, in a broad sell-off across Asian stock markets.
The report attributed the sell-off to dual concerns: first, hot US inflation reaching 3.7% in September, and second, the volume of debt financing the expansion of artificial intelligence infrastructure.
Rising financing costs for AI companies add pressure to their stocks, while investors await fresh signals from US markets to determine whether the decline will halt or extend to further sessions.
