The Consumer Price Index (CPI) rose 0.4% in October, exceeding economist expectations and reinforcing concerns about persistent inflation. The increase follows a 0.6% rise in September, according to data released by the Bureau of Labor Statistics on Tuesday. Core CPI, which excludes volatile food and energy prices, also climbed 0.3%, matching the prior month’s pace and surpassing forecasts of 0.2%. This marks the third consecutive month of core inflation holding steady at 0.3%, a level economists note remains above the Federal Reserve’s 2% annual target.
The latest figures arrive as the Fed prepares for its December policy meeting, where markets increasingly anticipate a 50-basis-point rate hike—double the typical quarter-point increase. Federal Reserve Governor Christopher Waller stated earlier this week that he would support a more aggressive stance if inflation remains elevated. “In that case, I believe a 50 basis point hike in the policy rate should be considered at the December meeting,” Waller said. “Hiking only 25 basis points would put our credibility at risk, a risk I am not eager to take.”
Treasury yields surged in response to the data, with the 10-year Treasury note climbing above 5% for the first time this month, reaching 5.004%. The 30-year bond yield rose to 5.364%, while the 2-year note, closely tied to Fed policy, jumped to 4.755%. Analysts at Goldman Sachs Asset Management suggested the hot CPI numbers could extend the Fed’s tightening cycle into 2027. “The Fed could push for a more-aggressive tightening cycle with CPI continuing to print strong,” said Lindsay Rosner, head of multi-sector fixed income investing.
Shelter and food costs drove much of the increase, with owners’ equivalent rent rising 0.3% and food prices climbing 0.5%. Grocery costs, including meat, dairy, and baby food, contributed to the rise, while lettuce prices jumped 7.3%. Transportation costs also accelerated, increasing 0.8%, and medical care services rose 0.3%. Energy prices, which had surged 5.2% in September, moderated to a 0.7% increase in October, offering some relief at the pump. The national average for a gallon of gasoline fell below $4 in early November, the first time since July, according to AAA data.
The annual inflation rate remains unavailable due to a federal government shutdown last October, which disrupted data collection. However, economists estimate inflation has accelerated on a year-over-year basis. The three-month annualized rate of headline inflation stands at 5.7%, while core inflation over the same period is 3.7%, indicating a sustained acceleration. The six-month annualized CPI is 3.2%, with core inflation at 2.6%.
Market reactions were immediate, with investors increasing bets on a larger December rate hike. Derivatives markets now assign a higher probability to a 50-basis-point increase, up from earlier expectations of a standard quarter-point move. Mark Zandi, chief economist at Moody’s, described the report as “uncomfortably high,” adding, “The Fed’s not going to be happy about it. It certainly makes it more likely we get another rate increase in December.”
The inflation data arrives amid political shifts following the midterm elections, where Democrats secured control of both the House and Senate, partly on voter concerns over affordability. President Donald Trump has acknowledged public frustration over gas prices and the Iran conflict, though no policy changes have been announced. The persistence of elevated inflation presents a challenge for policymakers, who must balance rate hikes to cool prices with the risk of slowing economic growth or labor market stress.
Federal Reserve officials have emphasized the need for broader disinflation before reconsidering their policy stance. Daniela Hathorn, senior market analyst at Capital.com, noted that while geopolitical tensions have eased slightly, underlying economic risks remain. “Lower energy prices could help ease inflation expectations, but the Fed will need evidence of broader disinflation before reconsidering its policy stance,” she said.
The October CPI report underscores the Fed’s dilemma: act decisively to curb inflation or risk allowing price pressures to become entrenched. With Treasury yields rising and market expectations shifting, the central bank faces mounting pressure to signal a more aggressive approach at its next meeting.
