Consumer prices rose 0.4% in October, and the government’s own index numbers put annual inflation at about 4%, a figure the Bureau of Labor Statistics was not able to print.
- Prices rose 0.4% from September, seasonally adjusted, against forecasts of 0.3%. Core prices, which leave out food and energy, rose 0.3% against 0.2%.
- The October report from the Bureau of Labor Statistics carries no year-over-year inflation rate, because the agency never collected October 2025 prices during last year’s shutdown.
- The last official annual rate on the books is September’s 3.7%.
- The Federal Reserve meets December 8 and 9, and traders have fully priced in a rate hike.
That missing number matters more than it looks. Every headline you saw this week led with “0.4%,” and a monthly figure tells you very little about how much more your groceries cost than they did a year ago. So we did the arithmetic the report could not.
How We Filled the Hole
The BLS publishes its raw price index every month, even when it cannot publish the annual change. You can pull it yourself from the agency’s data series for all items. Here is what it shows, not seasonally adjusted, which is how the annual rate is normally calculated:
- October 2026: 337.511
- September 2025: 324.800
- October 2025: missing
- November 2025: 324.122
Measure October against the month before the gap and prices are up 3.9% over 13 months. Measure it against the month after and they are up 4.1% over 11 months. Split the difference, treating October 2025 as the average of its two neighbors, and you get 4.0%.
That is an estimate, and we are labeling it as one. But every reasonable way of filling the gap lands between 3.9% and 4.1%, and all of them sit above September’s 3.7%. Inflation did not hold still in October. It moved up.
“BLS cannot publish 12-month percent changes for October 2026 for indexes where October 2025 data are unavailable.”
That sentence, from the release itself, is why you will see some outlets write “about 4%” with no working shown. Now you have the working.
Most of It Is Coming Out of Your Gas Tank
Run the same method on core prices and the picture splits in two. Core inflation, measured the same way, comes out at about 2.8%. Headline inflation is about 4%. The gap between those two numbers is energy.
The energy index is up 19.9% from September 2025. Gasoline, one of the few series the BLS did collect last October, is up 37.4% from a year ago. Since February, the gasoline index has climbed 44%, most of it after the war with Iran pushed oil above $100 a barrel and choked traffic through the Strait of Hormuz.
We covered the start of this in May, when inflation hit 3.8% as the war drove gas to a three-year peak. Six months on, it has not unwound. Gasoline rose 1.0% in October on a seasonally adjusted basis even though raw pump prices slipped 0.7%, because October prices usually fall by more than that.
Food rose 0.5%. Shelter rose 0.3% and, the BLS said, accounted for more than 30% of the monthly increase. Electricity rose 0.9%.
The Fed Has a Real Problem Too
Here is the part that should worry you even if you do not drive much. Core prices are not calm. Over the last three months, core inflation has run at an annualized pace of about 3.7%, well above the 2.8% it shows over the full year. The war’s energy costs are leaking into airfares, shipping and everything that moves on a truck.
Fed officials noticed. Governor Christopher Waller said before the report that a core reading “around 0.3” would make a half-point hike worth considering, and core came in at exactly that. Dallas Fed President Lorie Logan said she sees a need for two more quarter-point increases. Philadelphia Fed President Anna Paulson said “further gradual tightening seems appropriate.” CME’s FedWatch tool put the odds of a half-point move at 13.6%, up from roughly zero before the release.
The Fed’s benchmark rate sits at 3.75% to 4%. Chair Kevin Warsh, the man Trump picked expecting cuts, already delivered the first hike in three years in September, then held in October and left December open.
You Pay for This Twice
Think about what a December hike actually does. It does not reopen a shipping lane. It does not lower the price of a barrel of Brent. What it does is raise the rate on your credit card balance, your next car loan and any mortgage you have not locked, in the hope that you and everyone like you will spend a little less until the core number cools.
So the household that has spent since spring paying a war premium at the pump is about to start paying a second one at the bank. We think that is the honest way to describe where this is heading, and we think the bill belongs to the administration that chose the war and stacked tariffs on top of it, not to the central bank stuck cleaning up after both.
That does not make the Fed wrong to move. A 3.7% annualized core pace is too hot to ignore, and a central bank that waits for gas prices to fall on their own risks a year of 4% becoming the new normal. But you should be clear about what the hike is for. It is aimed at the spillover, not the source.
The Blind Spot Lasts Until Next Year
One more thing the report cannot tell you: when this gets easier to read. Any annual figure you see for October 2026 is an estimate like ours, and it will stay that way.
The November report is due December 10, the day after the Fed decides. November 2025 prices were collected, so that release will carry a real annual number again. The Fed will be voting without it, on a 4% it had to work out for itself, and you will find out the next morning whether it guessed right.
