Asian markets sell off as AI trades decline after US CPI data

by@Reuters

Summary

Asian markets experienced a significant sell-off on October 15, 2026, as the KOSPI plunged 5.6% and MSCI Asia-Pacific shares outside Japan fell 1.2%, following hotter-than-expected US consumer price inflation figures that heightened expectations for Federal Reserve interest rate hikes. The surge in inflation led to a rise in the implied probability of a 25-basis-point rate hike by the Fed at its October 28 meeting, now assessed at 31.6% up from 22.1%. The impact was particularly felt in the technology sector, where concerns over financing risks and IPO timelines contributed to the market's decline, reflecting persistent challenges in AI-related trades. Additionally, the Australian dollar weakened by 0.2% after local employment data showed a surprising decrease of 39,300 jobs in September.
