Global Markets Plunge as AI Spending and Rising Interest Rates Shake Tech Stocks
Global markets plunged as rising inflation and interest rate fears collided with soaring artificial intelligence infrastructure costs, wiping out billions in market value across Seoul, Wall Street, and Tokyo.
Global Market Sell-Off as AI Spending and Rising Interest Rates Shake Wall Street and Asia
After months where artificial intelligence acted as a magic word on Wall Street, investors are beginning to ask tougher questions about the true costs and return timelines of these massive investments. This growing skepticism triggered a cross-continent sell-off, hitting tech giants and chipmakers hard across global markets.
The turmoil initially erupted in Seoul at the start of the week. South Korea's KOSPI index plunged 5.46% on Tuesday and shed another 0.4%, before cascading into an 8% drop that triggered a temporary trading halt due to extreme volatility. Samsung Electronics lost roughly 9%, while SK Hynix plummeted over 11%.
Inflation Fears and High Debt Costs Pressure Tech Stocks
Wall Street caught the shockwave following a higher-than-expected Consumer Price Index print in the United States, which rose 3.7% year-over-year in September. The hotter inflation data revived fears that the Federal Reserve may need to hike interest rates further, pushing market expectations for an October rate increase from 22% up to roughly 37%.
For AI-driven equities, higher borrowing costs pose a severe threat. Data centers require tens of billions of dollars in funding for advanced chips, massive electricity supplies, real estate, and long-term debt financing. As interest rates climb, debt servicing costs surge dramatically. Companies heavily reliant on debt financing for infrastructure, such as CoreWeave, Nebius, Oracle, and Dell, suffered steep losses, wiping out approximately 80 billion dollars in market capitalization among leading AI firms.
The revolution in artificial intelligence is far from over, but the capital market is examining its underlying costs under a magnifying glass.
Asian Markets Follow Suit Amid Rising Competition
The panic quickly spread to Tokyo, where the Nikkei index tumbled nearly 5% during trading. SoftBank, a primary investor in technology bets, dropped nearly 10%, and memory manufacturer Kioxia plunged over 11%. Beyond financing pressures, memory chipmakers face fresh competitive threats from China, as CXMT announced advances in dense DRAM technology poised to challenge industry leaders.
