U.S. stocks declined after September consumer prices rose faster than Wall Street expected, prompting a sharp early jump in short-term Treasury yields and greater market odds of a Federal Reserve rate hike. The Nasdaq fell 1.9%, while investors awaited producer-price and retail-sales data for further clues about inflation and policy.
U.S. stocks fell on Wednesday after the government reported that consumer prices rose faster than Wall Street expected in September, renewing concern that inflation could keep interest rates higher, as seen in the latest market moves under rate pressure. The Nasdaq Composite dropped 1.9% to 26,692, while traders increased their expectations for a Federal Reserve rate hike and technology shares came under pressure.
The inflation report set off a fast move in the bond market. The two-year Treasury yield briefly jumped more than 10 basis points within minutes of the release, before easing during the session. By the close, it was up 1.5 basis points at 4.808%. Longer-term yields moved lower: the 10-year yield fell 2.7 basis points to 5.19%, and the 30-year yield dropped 4.6 basis points to 5.517%.
The selloff was concentrated in technology and other shares exposed to the AI buildout. The S&P 500 fell 1.1% to 7,719, while the Dow Jones Industrial Average slipped 0.09% to 51,622. Chipmakers recorded a seventh consecutive losing session, according to the market report. Nvidia fell 3.2%, and Caterpillar, an industrial company that can benefit from AI-related investment, dropped 3.1%.
ASML shares lost 3.9% despite a strong quarterly earnings report. The Netherlands-based chip equipment maker reported third-quarter revenue growth of 47% and earnings growth of 127%, narrowly missing the reported revenue expectation while beating the earnings estimate. Management raised its fourth-quarter sales guidance and said meeting chip demand in 2027 and 2028 would be difficult. Those results pointed to strong demand, but did not offset investor concern about inflation and market risk.

Nasdaq Nosedives as AI Boosts Consumer Prices
A hotter-than-expected September inflation report sent stocks lower and jolted short-term Treasury yields. Investors reassessed the rate outlook while chip shares continued their slide.
01 / Market reaction
A sharp repricing, with mixed yields
The inflation surprise pushed rate expectations higher and pressured growth-sensitive shares. Treasury markets moved in different directions by maturity.
Technology led the retreat
The selloff was concentrated in technology and other shares exposed to the AI buildout. Semiconductor stocks logged a seventh consecutive losing session.
The two-year yield jumped, then eased
Within minutes of the report, the two-year yield briefly rose more than 10 basis points. It gave back much of the move as the session continued.
Bars show the reported basis-point move relative to the largest move shown; directions are labeled.
02 / Policy watch
Inflation shifts the rate outlook
Hotter price growth can make policymakers more cautious about easing. Higher-rate expectations can weigh on shares valued on future growth.
That probability is a changing market estimate, not a Fed decision or a guarantee of what policymakers will do. Short- and long-term Treasury yields also finished with different moves, showing that the bond reaction was not uniform.
Barclays economist Pooja Sriram pointed to energy costs feeding into core prices, resilient consumer spending and AI-related price pressures as risks to the price-stability outlook. The available figures do not specify the exact consumer-price increase or the gap against forecasts.
“On balance, this morning’s inflation data are unlikely to provide much comfort to policymakers.”
— Pooja Sriram · Barclays economist03 / Company signals
Strong chip demand met market strain
Company results and outlooks offered evidence of demand, but did not insulate shares from the session’s inflation concerns and risk retreat.
Demand remains strong
Third-quarter revenue grew 47% and earnings rose 127%. ASML narrowly missed the reported revenue expectation while beating the earnings estimate.
Higher sales guidance
Management raised fourth-quarter sales guidance and said meeting chip demand in 2027 and 2028 would be difficult. The potential shortfall was not quantified.
Chip stocks stayed under pressure
ASML fell 3.9% despite the report. Nvidia lost 3.2%; Caterpillar, exposed to AI-related investment, dropped 3.1%.
ASML · Analyst view
Bank of America Securities analyst Didier Scemama reiterated a Buy rating and a $2,915 12-month target for ASML’s American depositary receipt, which closed at $1,650. These are analyst views, not company guidance or a certain future price. China shipment uncertainty around deep ultraviolet equipment remains a topic for investors.
Bank of America · Separate news
The stock fell 4.7% after a reported $1.2 billion Treasury Department fine tied to anti-money-laundering violations identified in a December 2024 consent order. Jefferies analyst David Chiaverini said the charge reduced earnings by 17 cents per share and maintained a Buy rating.

Quick answers
Key questions
Why did stocks fall?
September consumer prices rose faster than forecast, reviving concern that inflation could stay persistent and interest rates higher.
How did major indexes perform?
The Nasdaq fell 1.9% to 26,692, the S&P 500 lost 1.1% to 7,719, and the Dow slipped 0.09% to 51,622.
Did Treasury yields all rise?
No. The two-year yield ended 1.5 basis points higher at 4.808% after an early spike. The 10-year and 30-year yields finished lower.
What data were next?
Producer-price and retail-sales data for September were scheduled before Thursday’s opening bell, offering further clues on inflation and demand.
Inflation Recasts the Rate Outlook
The report matters because inflation readings influence expectations for the Federal Reserve’s next interest-rate decisions. Higher-than-expected price growth can make policymakers more cautious about cutting rates, while the prospect of tighter policy can weigh on stocks, particularly companies whose valuations depend on expected future growth. Wednesday’s market action showed investors reacting to that risk even as some technology firms reported robust demand.
CME FedWatch put the probability of a 25-basis-point rate increase at the October 27–28 meeting at 34.9%, up from 22.1% on Tuesday. That figure is a market-implied probability, not a Fed decision or a guarantee of what policymakers will do. The contrasting moves in short- and long-term Treasury yields also show that the bond market’s reaction was not uniform over the session.
Inflation concerns may also complicate the outlook for companies benefiting from AI investment. Barclays economist Pooja Sriram said risks including energy costs feeding into core prices, resilient consumer spending and AI-related price pressures were becoming more important to the price-stability outlook. The report does not establish that AI caused September’s inflation increase; it identifies AI-related price pressure as one concern economists are monitoring.

Chip Results Amid Market Strain
ASML’s update landed during a weak stretch for semiconductor shares. The company’s revenue and earnings growth, higher fourth-quarter sales guidance and comments about future demand offered evidence of continued activity in the chip supply chain. Yet the stock fell as investors weighed the inflation report and the wider retreat from risk-sensitive shares.
ASML also faces uncertainty over shipments of deep ultraviolet lithography equipment to China. Before the earnings report, Bank of America Securities analyst Didier Scemama described the issue as a hot topic for investors and said he thought it was largely reflected in the stock price. Scemama reiterated a Buy rating and a $2,915 12-month price target for ASML’s American depositary receipt, which closed at $1,650 on Wednesday. Those are the analyst’s views, not company guidance or a certain future price.
Financial shares also fell. Bank of America dropped 4.7% after a reported $1.2 billion Treasury Department fine tied to anti-money-laundering violations previously identified in a December 2024 consent order. Jefferies analyst David Chiaverini said the charge reduced earnings by 17 cents per share and maintained a Buy rating. The bank’s decline was a separate corporate development during a session dominated by inflation and rate concerns.

Inflation and Fed Path Remain Open
The reported figures do not resolve whether September’s inflation pressure will persist or how the Federal Reserve will respond. The market’s 34.9% rate-hike probability is a changing estimate, and the figures provided do not include the exact consumer-price increase or the size of the gap between the actual result and economists’ forecast.
It is also unclear how much of the day’s declines reflected the inflation report, ongoing weakness in chip shares, company-specific news or other market factors. ASML’s comments indicated demand for its equipment could exceed its ability to supply it in 2027 and 2028, but the available details do not quantify the shortfall. The effect of China shipment uncertainty on future sales was not specified.

PPI and Retail Sales in Focus
Investors were due to receive September Producer Price Index and retail-sales data before Thursday’s market open. The figures may provide additional evidence about price pressures and consumer demand, both of which can shape expectations for interest rates. They will not, on their own, determine the Fed’s decision.
Markets will also keep watching Treasury yields, upcoming company results and further information on the central bank’s policy outlook. Whether the stock decline extends will depend on how incoming data compare with expectations; the next session’s direction is not yet established.
