U.S. Core Inflation Rises 0.3% in October, Reaching Threshold for Rate-Hike Debate
Key Facts
The U.S. core consumer price index rose 0.3% in October from September, matching the increase for the third consecutive month, according to data released by the Bureau of Labor Statistics on November 10, 2026. The reading was higher than the 0.2% monthly increase forecast by economists surveyed by Reuters. Headline inflation also exceeded expectations by a tenth of a percentage point, according to the Associated Press. The headline index rose 0.4% during the month, after a 0.6% increase in September. The core reading puts markets’ focus on a threshold cited by Federal Reserve Governor Christopher Waller before the data were released, amid debate over the path of interest rates in December.
Waller said in a speech on the day the report was released that he would support a 25-basis-point increase at the December meeting even if inflation improved from its September reading. He added that core inflation remaining around 0.3% or rising could call for a stronger move, saying a 50-basis-point increase “should be considered” in that case. October’s reading came in at 0.3%, meeting the condition he set for considering the larger increase. Waller did not describe that as a settled decision, but tied it to the inflation reading and the path of incoming data. He also said inflation was “well above 2%,” the Federal Reserve’s target, and that he had been prepared to wait before tightening policy at the October meeting.
Price-basket components diverged in October, with the food index rising 0.5%, including a 0.4% increase in food at home and a 0.5% rise in food away from home, according to the Bureau of Labor Statistics. The energy index climbed 0.7% during the month, compared with a 5.2% increase in September. The gasoline index rose 1.0% after jumping 9.1% in the previous month, reflecting a sharp slowdown in the pace of monthly gains for that component. The shelter index increased 0.3%, contributing more than 30% of the monthly increase in the headline index. The slowdown in headline inflation from September thus coincided with continued increases in core inflation, while shelter costs remained a key driver of the monthly change.
The Bureau of Labor Statistics did not publish an annual inflation rate for October because the government shutdown in October 2025 prevented it from collecting consumer data for that month, according to Reuters. The bureau said it did not collect survey data in October 2025 because of a lapse in appropriations and therefore could not publish October year-over-year indexes for most price series. The annual headline reading was 3.7% in September, according to Reuters. The missing comparison month means October’s monthly reading is not accompanied by a comparable annual rate for some series. This limits the usual year-over-year comparison when assessing the path of prices, while monthly-change figures remain the published measure for the October release.
The higher-than-expected reading quickly affected markets: the yield on the 2-year U.S. Treasury note rose 13 basis points to 4.68% on November 10, according to Reuters. Nasdaq-linked futures fell 1.4%, while futures tied to the S&P 500 dropped 0.8%. Before the data release, futures had priced in a probability of about 85% of a rate hike at the Federal Reserve’s December 8 and 9 meeting, to a range of 4.00%–4.25%. The Associated Press also reported that stocks fell in early trading and Treasury yields rose as the figures were released. The market moves coincided with both headline and core inflation readings exceeding analysts’ forecasts, and core inflation reaching the level Waller said would warrant consideration of a larger increase.
The next focus is the October producer price index, scheduled for release on November 13, 2026, at 8:30 a.m. Eastern time, according to the Bureau of Labor Statistics calendar. The release comes before the Federal Open Market Committee meeting on December 8 and 9, according to the Federal Reserve’s official calendar. The bureau also scheduled the November consumer price index for release on December 10 at 8:30 a.m. Eastern time, one day after the meeting. These dates provide a sequence of data releases before and after the December decision. In Waller’s speech, the 25-basis-point increase remained his stated position even if inflation improved, while his proposal to consider 50 basis points was tied to core inflation remaining at 0.3% or higher.
