Global markets retreat as AI investment concerns trigger tech selloff

artificial intelligence semiconductor industry stock market volatility AI infrastructure debt VIX index

Global equity markets experienced a significant downturn as investors shifted away from the technology sector, driven by growing concerns regarding the sustainability of artificial intelligence (AI) infrastructure spending. The Nasdaq Composite and S&P 500 both fell below their 50-day moving averages, with the semiconductor sector facing intense pressure. The PHLX Semiconductor Index recorded eight consecutive days of declines, mirroring a broader retreat from high-valuation tech stocks.

Market volatility spiked, with the Cboe Volatility Index (VIX) rising significantly, at one point surging approximately 30% during intraday trading. This panic was exacerbated by rumors of large hedge fund liquidations and concerns over the high debt levels required to finance AI expansion. Specifically, global AI-related debt issuance dropped nearly 80% in September to $23 billion, and high interest rates have increased the cost of borrowing for data center projects.

In Asia, markets were hit hard by their heavy semiconductor exposure. South Korea’s KOSPI and KOSDAQ triggered circuit breakers following steep declines, while Japan’s Nikkei 225 and Taiwan’s weighted index also saw substantial losses. Conversely, energy sectors saw gains as oil prices rose due to geopolitical tensions in the Middle East and the Russia-Ukraine conflict. Investors also rotated into defensive sectors and safe-haven assets like US Treasuries, as US 10-year yields saw notable fluctuations amid inflation data that exceeded expectations.
