Stock Market News for Sep 11, 2026

U.S. stock markets declined on Thursday as surging oil prices and inflation data drove investor concerns about potential Fed rate hikes. Brent crude jumped 6.34% to $107.63 and WTI rose 6.69% to $102.48, both exceeding $100 for the first time since May. Rising Treasury yields and geopolitical tensions in the Middle East further pressured equities, with the Dow, Nasdaq, and S&P 500 all closing in the red. Markets are now pricing in a 70% probability of a Fed rate increase at next week's policy meeting.
