October 2026 CPI: Prices Up 0.4% and Mortgage Rates Rise

Consumer prices rose 0.4% in October 2026, the Bureau of Labor Statistics reported on Nov. 10. Economists surveyed by Dow Jones had expected 0.3%. Core prices, which leave out food and energy, rose 0.3% for the third month in a row, also one tenth above the forecast. It was the last Consumer Price Index report the Federal Reserve will see before its Dec. 8 and 9 meeting, and bond investors treated it as bad news: the 10-year Treasury yield climbed above 5% and mortgage rates rose the same day.

The report also had an unusual hole in it. For the first time in years, it carried no annual inflation rate.

Why There Is No 12-Month Number

The familiar headline figure, such as September's 3.7%, compares prices with the same month a year earlier. The federal government was shut down from Oct. 1 to Nov. 12, 2025, and the bureau did not collect prices that October. With no October 2025 index to compare against, the agency said it cannot publish 12-month changes for October 2026 for the overall index, the core index and most categories. The gap is explained in the Bureau of Labor Statistics CPI release.

The annual rate returns with the November report. Until then, the monthly figures carry the story, and they are not gentle. Three straight core readings of 0.3% work out to an annual pace of roughly 3.7%. A pace consistent with the Fed's 2% goal would be closer to 0.2% a month, as Moody's chief economist Mark Zandi told CNBC.

Where Prices Rose

• Shelter: up 0.3%, after 0.4% in September. The bureau said shelter accounted for more than 30% of the month's total increase. Owners' equivalent rent, the estimate of what homeowners would pay to rent their own homes, rose 0.3%. Rent rose 0.2%.
• Food: up 0.5% after no change in September. Groceries rose 0.4%.
• Energy: up 0.7%, a sharp slowdown from September's 5.2% jump. Electricity rose 0.9% and piped natural gas fell 0.8%.
• Gasoline: up 1.0% on a seasonally adjusted basis, after 9.1% in September. Actual pump prices fell 0.7% during the month. Gasoline is one of the few categories with a published annual figure, and it stood 37.4% above October 2025.
• Car insurance: up 0.7%. Transportation services as a group rose 0.8%.
• Used cars and trucks: down 1.2%, one of the few declines.

Energy is the thread running through much of this. Oil prices surged in 2026 after the war with Iran began, and higher fuel costs take months to work through shipping, airfares and groceries. That history is traced in the report on how the Iran war pushed 30-year mortgage rates above 7%. There was one piece of relief on the day of the report: AAA's national average for regular gasoline fell below $4 a gallon for the first time in nearly four months, according to CBS News.

What the Fed Does With It

The Fed raised its benchmark rate by a quarter point on Sept. 16 and then held it at 3.75% to 4% on Oct. 28, in a 10 to 2 vote. Both dissenters wanted another increase. The background is in the earlier report on the Fed holding rates at 3.75% to 4%.

Hours before the CPI release, Fed Governor Christopher Waller spoke in London and set out his own test. He said he would support a quarter-point increase in December in any case. If October's core CPI came in "around 0.3 percent or even higher," he said, a half-point increase "should be considered." The number landed exactly on his line. His full remarks are posted in the Federal Reserve's text of the speech.

One governor's view is not a decision. After the report, CME Group's FedWatch tool showed traders fully expecting a quarter-point increase on Dec. 9 and putting the odds of a half-point move at roughly 15%, up from near zero the day before. Dallas Fed President Lorie Logan said after the release that she sees a need for two more quarter-point increases. Several private economists quoted the same day said they expect the committee to stay with a quarter point.

Three reports arrive before the vote: producer prices on Nov. 13, the PCE price index (the Fed's preferred inflation measure) later in November, and the November jobs report on Dec. 4. The October jobs numbers already leaned toward a hike, as covered in the report on 165,000 new jobs and the December Fed meeting. The November CPI will not be out until Dec. 10, one day after the decision.

What It Did to Mortgage Rates

Mortgage rates follow the bond market, and bonds sold off as soon as the numbers came out. The 10-year Treasury yield rose about 0.13 percentage point to roughly 5.02% by midday on Nov. 10. Mortgage News Daily's daily index of 30-year fixed rates rose to 7.30%, up 0.12 point from the day before. Freddie Mac's weekly survey, which averaged 7.18% on Nov. 5, will not reflect the move until its next release.

In dollars: on a $400,000 loan, principal and interest come to about $2,710 a month at 7.18% and about $2,742 at 7.30%. That is $32 more each month from one day's move in the bond market.

A Fed increase in December would not add to that automatically. Lenders have already priced in a quarter-point hike, so the larger risk to mortgage rates is a surprise: a half-point move, or another hot inflation report.

What Buyers, Owners and Retirees Can Do

1. Buyers under contract: ask the lender what a rate lock costs through closing, and whether it includes a float-down if rates fall. With a Fed decision and three major reports ahead, a closing date in the next 30 to 45 days is exposed to more swings than usual.
2. Buyers still shopping: ask for payment quotes at two rates, today's and one a quarter point higher, so that a bad week in the bond market does not upend the budget.
3. Owners with a home equity line: most lines are tied to the prime rate, which moves with the Fed. A quarter-point increase adds about $2 a month in interest for every $10,000 owed. The details are in the guide to what another Fed hike means for mortgages, HELOCs and savings.
4. Owners with a fixed-rate mortgage: the payment does not change. Higher rates for new buyers are also one reason fewer owners list their homes, a pattern explained in the piece on the mortgage lock-in effect.
5. Retirees: the 3.6% Social Security cost-of-living adjustment for 2027 is already set. It was based on prices from July through September, so October's report does not change it.
