The pullback began in the U.S. as investors focused on rising energy costs and the bond market’s reaction. Stocks that had climbed toward records in recent sessions slipped after oil prices rose, which in turn pushed Treasury yields higher, pressuring valuations across the market. Traders also weighed how higher yields can affect everything from borrowing costs to expectations for interest-rate moves by the Federal Reserve.
Friday’s decline followed what had been a strong run for the market, including sharp gains tied to artificial-intelligence-related technology shares. The S&P 500 ended down 92.74 points at 7,408.50, the Dow Industrial Average fell 537.29 points to 49,526.17, and the Nasdaq composite sank 410.08 points to 26,225.14, as investors moved away from equities that had benefited most from the AI-driven rally. MSI previously reported that tech had lifted Wall Street to records as oil and inflation pressures lingered, and Friday’s reversal put that sensitivity to commodities back in focus.
Technology and AI-related stocks were among the most visible losers as the market turned lower. Nvidia, described by investors as a key bellwether for the AI trade, fell 4.4% and was the heaviest weighting in the S&P 500, according to the Associated Press. Micron Technology dropped 6.6%, adding to the pressure on semiconductor and other technology names that had fueled the market’s advance.
Investors also looked to the bond market for signals. Treasury yields climbed, with the 10-year Treasury rising to 4.59% from 4.47% late Thursday, and the 30-year Treasury reaching 5.13%. The report noted that yields have been climbing amid worries about higher inflation and how it might affect the Federal Reserve’s ability to cut short-term rates. Traders, the report said, have dialed back expectations that the Fed would resume rate cuts this year and have built expectations that rates could rise in 2026, based on data from CME Group.
Higher oil prices were the most immediate catalyst in the commodities-to-markets connection. Brent crude, the international benchmark, rose 3.3% to settle at $109.26 a barrel, and the Associated Press reported that the level is well above about $70 before the war. The report linked the pressure on oil prices to the continuing war with Iran and to the Strait of Hormuz remaining shut to oil tankers, which limits crude deliveries worldwide.
The report also pointed to the inflation risk behind the market reaction. It said rising oil prices are adding pressure after already worsening inflation by more than economists had feared, while the war with Iran and tariffs have left some households feeling discouraged. Even as some large companies reported their customers were still able to spend, the Associated Press said surveys showed households expressing more concern about the economy and about the pressures building for them.
Higher borrowing costs hit smaller companies more sharply than their larger rivals. The Russell 2000 index of smaller U.S. stocks fell 2.4%, about double the percentage decline of the broader S&P 500, as many smaller firms need cash to grow and can be more exposed to rate changes.
Outside the United States, equity markets also fell across regions. Europe and Asia saw broad declines of more than 1.5% in much of the region, with South Korea’s Kospi down 6.1% in one of its biggest moves. The report said the Kospi had set records earlier in the year due to AI beneficiaries such as SK Hynix, but it reversed course after briefly topping 8,000.
Market strategists and technical analysts characterized Friday’s move as a warning about volatility after a long run for tech. Brian Jacobsen, chief economic strategist at Annex Wealth Management, said in the report that markets appeared “overbought,” adding that profits and a durable U.S. economy remain intact but that “the path is unlikely to be smooth.” Jonathan Krinsky, chief market technician at BTIG, said the drop should serve as a “shot across the bow” for how volatility works in both directions.
