High Interest Rates Weigh on AI Trade

The steep decline was attributed to growing worries that elevated borrowing costs could undermine returns on the massive capital spending driving the AI boom, according to Yonhap News reporting of the market drop. Both benchmark indexes lost ground in the 7 percent range during the session, a scale of decline rare for the Korean market.

Investor sentiment deteriorated as doubts mounted over whether AI-related companies can sustain earnings growth under a high-interest-rate environment, pressuring technology-heavy listings on the KOSDAQ as well as large caps on the KOSPI.

The session drew the "Black Thursday" label in Korean media coverage, underscoring the severity of the one-day rout. The full extent of the impact on individual chipmakers and AI-related stocks was not detailed in the reporting.

The claim that high interest rates drove AI profitability concerns and a 7 percent-range collapse in the KOSPI and KOSDAQ on "Black Thursday" is True.
