Wall Street closed out Wednesday with its worst day since July, as a hotter-than-expected inflation report drove bond yields sharply higher, hammered chip stocks, and revived fears that the Federal Reserve will keep raising interest rates.
The S&P 500 sank 1.1% — its fifth loss in six days since setting an all-time high, and its first decline of at least 1% in more than 50 trading days, according to The Wall Street Journal. The Nasdaq composite tumbled 1.9% as artificial-intelligence stocks led the slide, while the Dow Jones Industrial Average slipped 48 points, or 0.1%, to close at 51,621.48.
The damage was worst in semiconductors. The PHLX Semiconductor Index plunged 4.3%, and the iShares Semiconductor ETF closed lower for a seventh straight session — its longest losing streak since May 2025, Barron’s reported. Advanced Micro Devices fell 5.7%, Intel dropped 4.6%, and Marvell Technology sank 8.7%. Nvidia, Microsoft, Amazon, Alphabet and other megacaps all lost ground; Apple was a rare gainer.
The selloff followed the Labor Department’s September consumer-price report, which showed inflation accelerating to 3.7% from a year earlier — above the 3.6% economists expected and up from 3.4% in August, the Associated Press reported. Gasoline drove more than half of the increase, and the monthly gain of 0.6% was the biggest in five months. Core inflation, which strips out volatile food and energy costs, also topped forecasts.
Bond yields were whipsawed: the 10-year Treasury briefly climbed above 5.32% after the report before retreating to 5.189% by the close — still leaving borrowing costs near multi-decade highs. Shorter-term yields jumped even more as traders priced in additional Fed rate hikes, though they eased later in the day, the Journal reported.
Banks were hit too. Bank of America tumbled nearly 5% after its quarterly profit disappointed, even excluding a $1.2 billion fine, and Morgan Stanley fell 2.7%. Healthcare was the one bright spot, with UnitedHealth Group jumping 4.7%.
Oil stayed elevated: Brent crude added 0.4% to close at $106.06 a barrel, with the AP noting inflation has accelerated in part because of fuel-price jumps tied to the war with Iran.
What it means for ordinary people
A hot inflation report plus rising yields is a double hit: mortgages, credit-card rates and auto loans tend to climb with Treasury yields, while higher prices for gasoline and food squeeze household budgets. The Federal Reserve’s Beige Book said businesses across the country are still feeling pressure from tariffs, commodity prices and insurance costs — and that some companies are slowing hiring as AI investments let them do more with fewer workers.
Bottom line: inflation is proving stickier than hoped, and the price of borrowing money is going up, not down — a drag on both household budgets and the stocks investors own.
