A monthly inflation figure can change after it first appears in a news report. On February 13, 2026, the U.S. Bureau of Labor Statistics (BLS) announced updated seasonal factors for the Consumer Price Index (CPI). Those updates can restate some earlier readings. A changed number does not automatically mean prices changed again or that the original report was mistaken. It may mean the statistical adjustment used to compare months has been updated.
What BLS changed, and why it matters
Seasonal adjustment is a way to account for patterns that tend to recur at particular times of year. For example, shopping and travel can follow calendar patterns. Removing those regular effects can make it easier to compare one month with the next. The BLS describes this process on its CPI seasonal adjustment page.
Seasonal factors are part of that adjustment. When BLS updates them, it can revise seasonally adjusted figures that were already published. A monthly rate in an older article may therefore differ from the rate shown later for the same month. The February 13 notice is titled “Updated seasonal factors”.
The available notice details here do not establish which individual series changed or by how much. So the important point is the possibility of a restatement, not a claim about the size or direction of any particular revision. When comparing figures, the publication date matters alongside the number itself.
CPI and PCE revisions do not necessarily arrive together
The CPI and the Personal Consumption Expenditures price index (PCE) are different measures of inflation. BLS produces the CPI, while the Bureau of Economic Analysis produces PCE. They use different methods and release schedules, so an update affecting one measure does not necessarily appear in the other at the same time.
A private economic commentary said that January 2026 CPI information reflected seasonal-factor revisions that were not reflected in the December 2025 PCE release. It also said the revisions were incorporated only partly into PCE in the January release, with full revisions expected later. That timing matters when readers compare CPI and PCE figures for nearby months: the measures may be at different stages of revision.
This does not make one index a substitute for the other. It means a comparison should identify the index and release date, rather than treating all inflation numbers as interchangeable readings from one shared series.
How to read the figures cited in private commentary
The commentary reported December 2025 core PCE inflation at 0.36% month over month and 3.00% year over year. “Core” means the measure excludes food and energy prices. The same commentary projected January core PCE at about 3.1% year over year. It described that projection as 110 basis points above the Federal Reserve’s 2% PCE inflation target. One basis point is one-hundredth of a percentage point, so 110 basis points equals 1.1 percentage points.
It also said the January monthly pace, expressed at an annualized rate, was on track for about 4.32%. An annualized rate takes a short-period change and expresses what it would amount to over a year if that pace continued. It is a way to describe a pace, not a guarantee that the same rate will persist. The commentary said the January figures would change as more inputs arrived.
These numbers are from a private analysis and include a projection. They are not official BLS or BEA figures. The commentary also pointed to a sharp decline in used-car prices in January CPI data and said that move was not sustainable. A large one-month change in one category is a reason to look at more than one data point, not proof by itself of a lasting trend.
How to check a figure that may have been revised
Start by identifying the measure: CPI or PCE. Then note the month being measured and the release date of the source. For a CPI number, the BLS notice and its seasonal adjustment explanation are useful starting points. The notice should be consulted directly for the details of the update. The information summarized here does not include the specific revision sizes or the exact series affected.
If a figure in an older story differs from a later table, compare the dates and labels before deciding what explains the gap. The later number may reflect a revised seasonal adjustment, but the available sources do not establish a way to identify every revised figure from a news report alone. Keeping a short note with the source, date, index and period makes later comparisons clearer.
What a statistical revision means for household costs
A revision changes the statistical account of price movements. It does not change what a household already paid for groceries, rent or a car. Nor do the sources establish that this particular update raises or lowers the cost of any household expense. An inflation index provides broad context; it is not a record of every person’s bills.
That distinction is useful when a revised monthly rate attracts attention. A changed reading can affect how analysts describe the recent pattern, but it is not itself a new price increase or decrease at a store. For a household, the actual amounts on bills and receipts remain separate from the revised historical series.
The clearest reading of an inflation number includes its index, month and publication date. Those details help explain why two credible reports can show different figures for the same period, especially when seasonal factors are being updated.
