US CPI Report: Latest Inflation Data and Release Schedule

The Latest US Inflation Numbers, the CPI Calendar Through 2027 and Two Years of Release-Day Data

Updated October 15, 2026. This page is refreshed after every CPI release; the next update follows the November 10, 2026 report.

The latest US Consumer Price Index (CPI) report, for September 2026, was released on Wednesday, October 14, 2026. Consumer prices rose 0.6% in the month and 3.7% from a year earlier, up from 3.4% in August. Core CPI, which excludes food and energy, rose 0.3% in the month and 2.6% over the year. The next CPI report, for October 2026, is scheduled for Tuesday, November 10, 2026, at 8:30 a.m. ET.

This is SimianX's permanent page for the US CPI report. Rather than writing a new preview and a new recap every month, we update this page after each release: the summary box, the release calendar and the table of the last 24 reports — with the S&P 500 and Treasury moves on each release day — always show the latest data from the Bureau of Labor Statistics (BLS).

Latest CPI report: September 2026

What the September report means. The 2026 inflation story is an energy story. Headline inflation was 2.4% as recently as February; energy prices then pushed it to 4.2% in May, its highest reading since April 2023, and after a dip in the summer it rose again in September as gasoline jumped. Core inflation has stayed in a narrow 2.4%–2.9% band all year, so the gap between headline and core — 1.1 percentage points in September — reflects energy rather than broad price pressure. That gap still matters to the Federal Reserve, which raised rates on September 16 to "support a timelier return" to its 2% goal. The Fed's next decision comes on October 28, before the October CPI is released; our always-updated Fed interest rate decision page tracks every move.

We report only the official BLS figures. Economists' consensus forecasts differ from survey to survey and are not published by the BLS, so we do not list them here.

CPI release schedule: remaining 2026 and 2027 dates

Every CPI report is released at 8:30 a.m. Eastern Time, before the US stock market opens. The BLS schedule lists these dates:

The report for December 2027 will be released in January 2028; the BLS has not yet scheduled it. Note the three meetings — December 2026, June 2027 and December 2027 — at which the Fed decides before that month's CPI is out. At those meetings the latest CPI the Committee has seen is about four weeks old, which raises the weight of the previous month's report.

The last 24 CPI reports: inflation data and market reaction

The table lists the last 24 published reports, newest first. Monthly changes are seasonally adjusted and shown as first reported; 12-month changes are not seasonally adjusted. The two market columns show the close-to-close change on the release day: the S&P 500 in percent, and the 2-year Treasury yield — the maturity most sensitive to expected Fed policy — in basis points.

Two notes on the data. First, the BLS revises seasonally adjusted figures every February for the previous five years, so a few of the 2024–2025 monthly changes now read 0.1 point differently in the BLS database; the 12-month changes are never revised. Second, there is no October 2025 report, and the November 2025 report had no monthly change, for reasons explained below.

What two years of CPI data show

1. Disinflation stalled in 2025. Headline inflation spent the year between 2.3% and 3.0%, and core between 2.6% and 3.3%. Inflation never fell back to the 2% area that the Fed was waiting for.
2. The 2026 rise was an energy shock. Headline CPI jumped 0.9% in March 2026 alone — the largest monthly increase since June 2022 — and climbed to 4.2% over 12 months in May. Energy is only 6.4% of the CPI basket, but with the energy index up 20.4% over the year it adds roughly 1.3 percentage points to the headline rate on its own.
3. Core inflation barely moved. Core CPI ranged from 2.4% to 2.9% throughout 2026. In May the headline rate ran 1.3 points above core, the widest gap since October 2022.
4. Shelter is still the biggest single input. Shelter makes up 35.6% of the CPI and about 45% of core, so its monthly change — 0.4% in September — sets the floor for core inflation more than any other component.

How stocks and bonds react on CPI day

Over these 24 release days the S&P 500 rose 13 times (54%) and moved by an average of 0.70% in either direction, only slightly more than the 0.67% average on all other trading days over the same period. The 2-year Treasury yield moved by 4.5 basis points on average. Five release days produced a stock move of 1% or more, and they show why a CPI print alone rarely explains the day:

• April 10, 2025 (−3.46%). A soft report (−0.1% headline, +0.1% core) could not prevent a sell-off the day after the S&P 500's 9.52% rally on the pause in tariff increases. Trade policy, not inflation, drove that session.
• January 15, 2025 (+1.83%). Core inflation cooled to 0.2% after four straight 0.3% readings, and the 2-year yield fell 10 basis points.
• June 10, 2026 (−1.62%). Headline inflation reached 4.2%, the high of the energy shock.
• August 12, 2025 (+1.13%). Headline rose 0.2% and core 0.3%; the 2-year yield slipped 4 basis points, and the Fed went on to cut rates five weeks later, on September 17.
• October 14, 2026 (−1.11%). The September report showed a 0.6% monthly jump driven by gasoline.

The two hottest core readings in the table — 0.4% for January 2025 and April 2026 — were both followed by modest stock declines (−0.27% and −0.16%) and a higher 2-year yield (+7 and +5 basis points). For crypto, where CPI days have produced much larger swings, see our US CPI vs crypto playbook.

Why there is no October 2025 CPI report

The BLS did not collect CPI data from October 1 through November 12, 2025, during the lapse in federal government appropriations. As a result, the October 2025 report was never published, and the BLS database has no October 2025 value for the all-items or core index. The November 2025 report, released on December 18, gave 12-month changes but no monthly change, because there was no October index to compare with. The BLS says the missing October data also affected the April 2026 rent and owners' equivalent rent indexes, because each rental unit in the BLS sample is priced once every six months. Its shutdown impact page documents the effects.

How to read a CPI report

1. Headline versus core. Headline CPI covers everything consumers buy. Core CPI removes food and energy, whose prices swing with weather and oil markets, to show the underlying trend. Core accounted for 79.9% of the index in December 2025.
2. Monthly versus annual. The monthly change is seasonally adjusted and shows the latest momentum; the 12-month change is not seasonally adjusted and changes slowly. A 0.3% monthly increase works out to about 3.7% a year if repeated, so a run of 0.3% readings keeps core inflation well above 2%.
3. Rounding matters. The BLS rounds to one decimal place, so a "0.3%" can be anything from 0.25% to 0.34%. Markets often react to the second decimal, which analysts compute from the index levels.
4. Table A is the summary. The first table in every release shows the last seven monthly changes for each major component, plus the 12-month change. It is the quickest way to see whether a surprise came from energy, food, shelter or core goods.
5. Seasonal revisions every February. With the January report, the BLS recalculates seasonal factors for the past five years. The latest update, on February 13, 2026, covered January 2021 to December 2025.
6. CPI is not the Fed's target. The Fed's 2% goal is defined in terms of the PCE price index, which the Bureau of Economic Analysis publishes later each month. PCE gives shelter a smaller weight than the CPI. In the September 2026 projections, Fed officials expected PCE inflation of 3.7% and core PCE inflation of 3.4% for 2026.

How this page is updated

How this page is updated: after every CPI release. On each release day we refresh the "Latest CPI report" box after the 8:30 a.m. ET publication, add the new month to the table of the last 24 reports (and drop the oldest), record the S&P 500 and 2-year Treasury moves at the close, and roll the "next release" date forward. Each February we note the BLS seasonal revisions, and when the BLS publishes the following year's release schedule we add it to the calendar. Last updated: October 15, 2026. The next update follows the October 2026 CPI report on November 10.

Frequently asked questions

What is the current US inflation rate?

Consumer prices rose 3.7% in the 12 months to September 2026, according to the CPI released on October 14, 2026. Core inflation, excluding food and energy, was 2.6%.

When is the next CPI report?

The October 2026 CPI will be released on Tuesday, November 10, 2026, at 8:30 a.m. ET. The November 2026 report follows on Thursday, December 10, 2026.

What time is the CPI released?

The BLS publishes the CPI at 8:30 a.m. Eastern Time, one hour before the New York Stock Exchange opens.

What is the difference between headline and core CPI?

Headline CPI measures the prices of all goods and services in the basket. Core CPI excludes food and energy, which are volatile, to show the underlying trend. In September 2026, headline was 3.7% and core 2.6%, a gap that mostly reflects higher energy prices.

Why was there no October 2025 CPI report?

The BLS did not collect price data from October 1 to November 12, 2025, during the federal government shutdown, so it never published an October 2025 report or October index values.

Does the stock market go up or down on CPI day?

Neither reliably. Over the last 24 reports the S&P 500 rose on 13 release days and fell on 11, with an average move of 0.70% in either direction. The biggest moves often reflected other news on the same day.

Which inflation measure does the Fed target?

The Fed targets 2% inflation as measured by the PCE price index, not the CPI. The two usually move together, but the CPI gives more weight to shelter, so it has tended to run higher.

Who publishes the CPI?

The U.S. Bureau of Labor Statistics, part of the Department of Labor, publishes the CPI every month. The data and full release archive are on bls.gov.

Methodology and sources

• Inflation figures come from each monthly BLS CPI news release (Table A), using the values first reported for the reference month. Every 12-month change was cross-checked against the BLS index levels for series CUUR0000SA0 (all items) and CUUR0000SA0L1E (core) from the BLS public data API, and all matched.
• Release dates are from the BLS release archive and its published CPI release schedule. FOMC dates are from the Federal Reserve's meeting calendar.
• Weights are the BLS relative importance of CPI components for December 2025.
• S&P 500 changes are close-to-close price changes on release day from Yahoo Finance, cross-checked against CNBC's index history and FRED; all three matched for every release day. "Other trading days" covers October 2024 to October 2026, excluding the 24 release days.
• Treasury yields are U.S. Treasury daily par yields; the change is from the previous trading day's close. Data compiled October 15, 2026. This page is for information only and is not investment advice.
