Global Stocks Fall as Treasury Yields Hit New Highs

Global stock markets declined on Wednesday, October 8, 2026, as investors reacted to rising bond yields, geopolitical instability in the Middle East, and uncertainty surrounding central bank policies. In the United States, the Dow Jones Industrial Average led the losses, falling 0.66% to 51,180.17, while the S&P 500 and NASDAQ Composite both decreased by 0.22%.

Treasury yields reached new peaks, with the 10-year note climbing to 5.365% and the 30-year note surging to 5.732%. This trend triggered a broader international selloff, including a 1.70% drop in Canada's S&P/TSX Composite and a 2.48% decline in South Africa's Top 40. Mainland China's SSE Composite Index was the only major market to buck the trend, posting a gain of 0.31%.

In currency markets, the U.S. dollar strengthened against the euro and British pound. However, it remained marginally weaker against the Japanese yen as markets speculated on the policy path of the Bank of Japan. The Federal Reserve System's signals regarding interest rate trajectories further contributed to market caution and the strengthening of the dollar.
