Global equity markets came under heavy selling pressure on October 22, 2026, as surging oil prices and a sharp pullback in AI-linked stocks rattled investors from New York to Asia. The Nasdaq fell 2.1%, the S&P 500 lost 1.3%, and the Dow Jones Industrial Average dropped 279 points. By mid-morning in New York, the Nasdaq was down 1.5% and the S&P 500 had lost 0.8%, with Nvidia sliding 2.3% and weighing heavily on broad index funds.
Brent crude, the global oil benchmark, jumped 2.6% to $111.66 per barrel, its highest level in five months, while US crude neared $100. The move came after former President Trump warned that something could happen soon with Iran, adding geopolitical risk to an already tense energy market. Gasoline prices had already risen 9.1% in September, and the oil shock is now showing up at the pump alongside the stock market rout.
AI and semiconductor names were among the hardest hit as investors questioned massive AI spending. Meta dropped 5.8% after its profit missed forecasts, CoreWeave fell 3.8% on debt concerns, Lam Research slid 7.7% after guiding profit below estimates, and AMD, Micron and Nvidia also declined. Citadel founder Ken Griffin said investors are almost certainly in an AI bubble, comparing AI chips to airline seats that cost little to run once purchased and can collapse in price when supply outruns demand.
Asian markets suffered steep losses as well. South Korea's Kospi fell 3.52% to 5,533.77, Japan's Nikkei 225 dropped 2.65%, and Hong Kong's Hang Seng lost 3.03%. China's CSI 300 entered bear market territory, defined as a 20% decline from a recent peak. The selling followed the Kospi's 7.57% plunge on October 15, a session dubbed "Black Thursday" that triggered a circuit breaker, with the index still more than 40% below its June peak.
The 10-year Treasury yield stood at 5.03%, up from 3.97% before the Iran war, keeping pressure on risk assets. The Federal Reserve's next rate decision is due October 28, with markets pricing roughly a 15% chance of another hike and a December increase still widely expected. Core PCE inflation data follows on October 29, and October payrolls arrive November 6. For digital assets, this risk-off environment, higher oil, rising yields and Fed uncertainty are likely to keep speculative appetite subdued in the near term.
