US stocks closed lower Wednesday for a third consecutive session as higher Treasury yields and rising oil prices weakened investor sentiment. The Dow Jones Industrial Average fell 0.77% to 52,380.66, while the S&P 500 declined 0.48% to 7,636.36 and the Nasdaq Composite lost 0.64% to 26,253.34. The 10-year Treasury yield reached 4.857%, its highest level since November 2023, after the Treasury Department said it would triple its buyback of longer-dated government debt to $6 billion. Oil prices climbed as tensions between the US and Iran raised concerns about further Middle East supply disruptions. US President Donald Trump said the war with Iran would end immediately after the Nov. 3 midterm elections and said recent US strikes in the Strait of Hormuz had incapacitated about nine Iranian tankers. Brent crude rose 3.8% to $101.64 a barrel and West Texas Intermediate jumped 4.1% to $96.85, with both reaching their highest settlement levels since May. The CBOE Volatility Index (a measure of expected stock-market volatility) rose 4.71% to 16.46. European shares also declined, with the STOXX Europe 600 down 1.41% to 640.41 points and major national benchmarks posting losses.
