The tech market sell-off deepened on Thursday as global stocks plunged amid rising US inflation and mounting fears over AI debt. South Korea’s KOSPI 200 index plummeted over 8%, triggering circuit breakers, while Japan’s Nikkei 225 fell 4.9%. The rout followed Wall Street’s worst session since July, with the Nasdaq Composite dropping 1.9%.
US Inflation Sparks Rate Hike Fears
New data revealed that US inflation jumped to a higher-than-expected 3.7% in September, the fastest increase since May’s 4.2% peak. This has rattled investors who now anticipate fresh interest rate hikes from the Federal Reserve, possibly as soon as the end of the month. Rising rates typically pressure growth stocks, especially those in the heavily indebted tech sector.

AI Debt Concerns Amplify Sell-Off
The sell-off was particularly severe in AI-linked shares. SK Hynix and Samsung Electronics plunged nearly 11% and 9.5%, respectively, dragging the KOSPI to a six-month low. In Japan, memory chip maker Kioxia slumped 11%, and SoftBank, a major investor in OpenAI, dropped 10%. Investors are increasingly wary of the massive debt accumulated by companies racing to capitalize on artificial intelligence.
