Stock Market on Sept. 10, 2026: Dow, S&P 500 and Nasdaq end lower as U.S. oil prices surge to more than $100 a barrel and Treasury yields jump; stocks book 4th straight day of losses

U.S. equities posted their fourth consecutive losing session on Sept. 10, 2026, as oil prices breached $100 per barrel and Treasury yields climbed. The Dow, S&P 500, and Nasdaq all closed lower, pressured by the twin headwinds of surging energy costs and rising borrowing rates.

The oil spike past the psychological $100 threshold marks a significant shift for inflation-sensitive sectors and threatens to reignite Federal Reserve tightening concerns. Higher energy input costs typically compress margins for industrials and consumer-facing companies, while elevated Treasury yields make equity valuations less attractive on a relative basis.

The four-day losing streak reflects growing unease among investors weighing the drag from higher oil against a backdrop of sticky interest rates. Energy-intensive industries face margin compression, while the broader market contends with competing asset classes as yields rise. The convergence of these two forces amplifies downside pressure across major indexes.
