Stocks Decline as Crude Oil Prices Rise and Bond Yields Increase
On August 31, 2026, major U.S. stock indices ended mostly lower due to rising crude oil prices driven by renewed Middle East tensions. The S&P 500 fell -0.33%, the Dow Jones Industrial Average dropped -0.70%—a one-week low—and the Nasdaq 100 edged up slightly at +0.08%. Crude oil surged over +2% after U.S.-Iran strikes, pushing bond yields to a 19-month high of 4.77%, which raised inflation concerns and complicated the Federal Reserve’s outlook. The market also reacted negatively to comments from Fed Chair Warsh, who indicated support for rate hikes amid inflationary pressures. The probability of a September FOMC rate hike increased to 65%. Despite this, energy stocks rose due to higher oil prices, while cybersecurity and cryptocurrency sectors provided some relief in the Nasdaq. Earnings season has been strong so far, with AI-driven growth contributing significantly to S&P 500 earnings. However, geopolitical risks remain a key factor weighing on investor sentiment.
