    Question

    U.S. Indices Fall as 30-Year Treasury Yield Touches 2004 High

    Direct answer

    U.S. equity benchmarks declined for a second straight session on September 24, 2026. The Nasdaq Composite retreated 0.77% to 0.8%, the S&P 500 fell roughly 0.5%, and the Dow Jones Industrial Average dropped around 0.6% to 0.71%. The primary cross-asset headwind was a sharp expansion in long-end sovereign yields, with the 30-year Treasury yield touching levels unseen since 2004. Geopolitical tensions also exerted upward pressure on crude oil prices, reinforcing rate-sensitive risk-off positioning. — bearish pressure on COMP.
