US stocks extended their decline to a third consecutive session on Wednesday as rising Treasury yields and a renewed oil-price surge pressured sentiment. The Dow Jones Industrial Average fell 0.77% to 52,380.66, while the S&P 500 slipped 0.48% to 7,636.36 and the Nasdaq Composite declined 0.64% to 26,253.34. The Treasury Department said it would triple its buyback of longer-dated debt to $6 billion, but the announcement did not prevent the 10-year yield from climbing to 4.84%, its highest level since November 2023. Brent crude settled 3.36% higher at $101.21 a barrel, and West Texas Intermediate (WTI), a U.S. oil benchmark, rose 3.25% to $96.05. Escalating tensions between the US and Iran have raised concerns about disruptions to Middle East energy supplies, adding pressure to an already strained bond market. Thomas Martin of Globalt Investments said extreme bullish equity sentiment and expectations for higher interest rates represented an unusual standoff that could not persist indefinitely. The losses came after the Dow suffered its worst single-day decline in nearly three weeks on Tuesday, at the start of a holiday-shortened week following Monday’s Labor Day closure.
