Tech market sell-off deepens amid fears over US inflation and AI debt

Chip makers and tech investors were hit hard as a wave of AI‑linked share sell‑offs swept global markets, driven by fears of rising U.S. inflation and the prospect of further Federal Reserve rate hikes. South Korea’s Kospi 200, dominated by memory‑chip producers, tumbled more than 8% overnight to a six‑month low, triggering circuit‑breaker halts; semiconductor giants SK Hynix and Samsung Electronics fell nearly 11% and 9.5% respectively. Japan’s Nikkei 225 dropped 4.9% after memory‑chip maker Kioxia slumped 11% and SoftBank, a major OpenAI investor, slid 10%. The decline followed a Wall Street slide the previous day, with the Nasdaq Composite down 1.9% and the S&P 500 off 1.1%, its worst performance since July.
The sell‑off was sparked by U.S. consumer‑price data showing September inflation rising to an unexpected 3.7%, the fastest increase since the CPI peaked at 4.2% in May, prompting traders to price in another Fed rate hike as early as month‑end. Deutsche Bank analysts led by Jim Reid noted that the inflation spike was broad‑based across the consumer basket, not limited to energy costs, and that the strong CPI print compounded mounting worries about the AI trade. The International Monetary Fund warned that a correction in AI‑related equities could threaten global financial stability, flagging Asian markets as the most exposed while the UK and eurozone might be relatively insulated.
The ripple effects reached China, where the Shanghai‑Shenzhen CSI 300 fell 2.4% to its lowest level since August 2025, and Taiwan’s TSMC slipped 2% despite a sixth consecutive profit‑raising quarter. European indices opened lower, with the Stoxx 600 down 0.4% and Germany’s DAX off 0.53%, while U.S. tech futures pointed to further losses, the Nasdaq 100 futures dropping 1%. The combined pressure from inflation data and AI‑sector vulnerability suggests continued volatility for investors with exposure to tech and semiconductor stocks worldwide.
