US stocks fell for a third consecutive session on Wednesday, September 9, 2026, as a fresh surge in oil prices and a jump in Treasury yields kept investors on the defensive. Crude oil pushed past $100 a barrel amid renewed US-Iran tensions, stoking worries about inflation and corporate profit margins, while a climb in borrowing costs added to the pressure on equities. All three major indexes closed in the red, with technology shares leading the retreat.
What Moved Markets
The Dow Jones Industrial Average shed 404.99 points, or 0.77%, to close at 52,381.08. The S&P 500 slipped 37.16 points, or 0.48%, to finish at 7,636.36, and the Nasdaq Composite dropped 168.07 points, or 0.64%, to end at 26,253.34.
The main driver was a renewed spike in energy costs. With crude oil topping the $100 mark, traders grew concerned that higher fuel prices would feed through to broader inflation just as the Federal Reserve weighs its next move. Adding to the unease, the 10-year Treasury yield rose about 3 basis points to roughly 4.83%, its highest level in nearly two years. Yields climbed after Treasury Secretary Scott Bessent said the department plans to expand its bond buyback program, a headline that unsettled the bond market. Rising yields tend to weigh on stock valuations, particularly for growth and technology names, and the Nasdaq 100 bore the brunt of the selling with a loss approaching 1%. A jump in the CBOE Volatility Index, often called the market’s fear gauge, underscored the cautious mood.
Notable Movers
Marvell Technology (MRVL) was a bright spot, climbing about 6.4% after management delivered a sharp upward revision to its revenue targets. The chipmaker now guides toward roughly $12 billion in fiscal 2027 revenue and about $18 billion in fiscal 2028, a signal of strong demand for its data-center and AI-related products.
Chevron (CVX) gained around 2.5% as the leap in crude oil prices lifted energy shares across the board, making the sector one of the few pockets of strength in an otherwise weak tape.
Casey’s General Stores (CASY) tumbled nearly 15% even after posting an earnings beat, as investors focused on cautious forward guidance and worried that higher fuel costs could squeeze the convenience-store operator’s margins.
Alphabet (GOOGL) fell about 3.2% and Salesforce (CRM) lost roughly 3%, as megacap technology and software names came under pressure from the rise in yields and a broad rotation out of high-growth stocks.
Looking Ahead
Investors will keep a close watch on the path of oil prices and any further developments in US-Iran relations, since sustained crude above $100 could complicate the inflation picture. The direction of Treasury yields will also be front and center, along with upcoming economic data and Kroger’s fiscal second-quarter results due later in the week. With volatility ticking higher, retail investors may want to brace for choppier trading and focus on how rising energy and borrowing costs filter into corporate outlooks in the sessions ahead.
