Consumer prices rose 0.4% in October, more than expected, complicating Fed's inflation fight

Costs for goods and services rose more than expected in October, providing fresh warning signs for the Federal Reserve in its fight to lower inflation.

The consumer price index, a broad gauge of costs across the U.S. economy, increased a seasonally adjusted 0.4% for the month, the Bureau of Labor Statistics reported Tuesday. Economists surveyed by Dow Jones had been looking for a 0.3% increase.

Stripping out volatile food and energy, so-called core CPI increased 0.3% against the forecast for a 0.2% gain.

The headline CPI had increased 0.6% in September while core was up 0.3%.

The report comes at a critical juncture for the Federal Reserve as it considers its next interest-rate move. Speaking Tuesday morning in London ahead of the CPI release, Fed Governor Christopher Waller said a hot inflation report could push him toward advocating for a half-point increase in December, and specifically said such a hike should be on the table if core CPI was “around 0.3.” 

Hours later, that’s exactly what happened. 

Traders are now fully pricing in a quarter percentage-point increase when the Fed next meets Dec. 8-9, and put odds of a half-point hike at 13.6%, after being around zero prior to the inflation report, according to the CME Group’s FedWatch tool.

Stocks fell following the release, while Treasury yields jumped. 

“This was the report the market could least afford to see,” said Karen Manna, fixed income investment strategist at Federated Hermes. “A hotter inflation print raises fresh questions about whether the Fed has done enough to contain price pressures and reinforces the risk that interest rates need to move higher and stay there for longer.”

The BLS did not estimate a yearly rate in its October inflation report. The government shutdown last year prevented the bureau from collecting sufficient data in October 2025, so there is no comparable figure to use. However, the report did include annual figures for some individual items where it was able to collect data.

Though gasoline prices have been falling in recent weeks, the energy index rose 0.7% and the gasoline index was up 1%. The natural gas index, though, was off 0.8%.

Food costs accelerated 0.5%, pushed higher by increases of 1% for snacks, 0.9% for beef and 0.5% for meats, poultry, fish and eggs. Transportation services jumped 0.8%. New vehicle prices increased 0.2% but used cars and trucks fell 1.2%.

Shelter costs were higher by 0.3%, which the BLS said accounted for more than 30% of the headline increase.

Apparel, a tariff-sensitive sector, rose just 0.1%. Medical care commodities prices increased 0.5%. Airline fares accelerated 0.4%.

At the Fed’s October meeting, central bank officials voted 10-2 to keep their benchmark rate in a range between 3.75%-4% while awaiting incoming data.

Markets already had been expecting the Fed to hike its benchmark borrowing rate next month, but the inflation data may have sealed the deal. 

Despite the moderating gas prices recently, Fed officials have expressed concern that the impacts from the Iran war and President Donald Trump‘s tariffs are becoming embedded in the economy. Inflation has been running above the Fed’s 2% target for some 5½ years.

Dallas Fed President Lorie Logan, speaking Tuesday after the inflation report, said she sees a need for two additional quarter-point increases. Logan noted that the CPI report was “higher than expected” and said she is worried that the Fed’s primary inflation-forecasting metric, the personal consumption expenditures price index, also could move higher when it is reported later in November.

“It may be possible to move more rapidly this winter than the [Federal Open Market Committee] has moved so far this fall,” she said. “After two more increases are in place, it would make sense in my view to pause and examine economic and financial developments to determine what further action may be appropriate.”

In addition to tariffs and the war, inflation has been pressured by hyperscaler spending in the artificial intelligence buildout. Electricity prices rose 0.9%, a potential complication from the AI story.

Consumers, though, continue to spend — retail sales rose 0.8% in September, according to the Commerce Department — and businesses are still raising prices.

A net 37% of businesses responding to the October National Federation of Independent Business survey reported that they plan to raise prices in the next three months, the highest level since July 2022.
