Published October 15, 2026 (BLS release of October 14). Market data (CoinGecko, CME FedWatch) as of 17:45–17:55 UTC.

Key takeaways

US consumer prices rose 0.6% in September 2026 from August and 3.7% from a year earlier, the Bureau of Labor Statistics said on October 14, 2026 (BLS CPI release). Economists expected 0.6% and 3.6%. The monthly rise matched the forecast; the annual rate came in 0.1 point above consensus and 0.3 point above August's 3.4%.
Core CPI (excluding food and energy) rose 0.3% on the month and 2.6% on the year, against expectations of 0.2% and 2.5%. Both measures beat forecasts by 0.1 point, and the annual rate rose from 2.4% in August.
Energy drove the headline: gasoline jumped 9.1% on the month (seasonally adjusted) and accounted for over half of the monthly increase. The energy index is up 20.4% year over year (gasoline +34.2%). Shelter rose 0.4% (3.2% y/y) and food was flat (2.5% y/y).
Before the release, CME FedWatch priced a 78.4% chance of no change and a 21.6% chance of a 25 bp hike at the October 28 FOMC. After the data (about 17:55 UTC on October 14): 65.1% no change and 34.9% hike.
Bitcoin fell from $83,697 at 12:30 UTC to $82,797 five minutes after the release (−1.1%) and traded at $81,717 at 17:45 UTC, −2.4% since the release ($83,116 on the evening of October 13, per CoinGecko).

Calculations by BullishStation from the BLS release (September data published October 14, 2026) and the forecasts above.

Verdict: hotter than expected, mainly on core. The 0.6% headline rise matched forecasts, and gasoline (+9.1%) did most of that work. The surprise for the Fed is core at 0.3% against 0.2% expected, with shelter re-accelerating to 0.4% and gains in airline fares (+1.2%), used cars (+0.7%) and recreation (+0.5%).

Our calculation: what the market was really testing

Using the seasonally adjusted index levels published by the BLS and mirrored on FRED (CPIAUCSL and CPILFESL), we checked how each monthly outcome maps to the annual rate. In September 2025 headline prices rose 0.30% and core prices 0.22%, so any September 2026 reading above those levels pushes the yearly rate up.

September m/m outcome	Headline y/y (SA approx.)	Core m/m outcome	Core y/y (SA approx.)
0.4%	3.46%	0.1%	2.33%
0.5%	3.56%	0.2%	2.43%
0.6% (consensus)	3.67%	0.3%	2.53%
0.7%	3.77%	0.4%	2.63%

Calculations by BullishStation from FRED index levels (August 2026: 334.131 headline, 337.765 core; September 2025: 324.245 and 330.418). The official year-over-year rates use unadjusted data and can differ by about 0.1 point.

Headline is an energy story. Headline CPI fell 0.4% in June, then rose 0.1% in July and 0.4% in August, following energy prices (−5.7%, −1.5%, +2.1% month over month).
Core momentum was calmer than the yearly rate. Core CPI rose about 2.0% at an annualized pace over the three months to August (June to August), below its 2.4% year-over-year rate. September's core reading of 0.3% breaks that trend: with July at 0.2% and August and September at 0.3%, the three-month annualized pace rises to roughly 3.2% (our calculation from the rounded BLS monthly changes).
Actual vs model: the gap between the actual core reading and the Cleveland Fed nowcast (0.20%) is about +0.1 point (0.3% published, rounded): the main upside surprise of the report.

What it means for the Fed and the October 28 FOMC

The FOMC raised the federal funds target range by 25 basis points to 3.75%–4.00% on September 16, 2026, by a 12–0 vote. Its next meeting is on October 27–28, with no new economic projections; the next projections come in December. Every decision since 2025 is in our Fed rate decisions and Bitcoin tracker.

CME FedWatch probabilities	Oct 13, 2026 (before CPI)	Oct 14, 2026 (after CPI, ~1:55 p.m. ET)
Oct 28: no change (3.75%–4.00%)	78.4%	65.1%
Oct 28: +25 bp (4.00%–4.25%)	21.6%	34.9%
Oct 28: cut	0.0%	0.0%
Dec 9: at least one more hike by then	89.5%	92.4%
Dec 9: 4.25%–4.50% (two hikes)	18.7%	30.8%

Source: CME FedWatch, read on October 13, 2026 at about 19:20 UTC and on October 14 at about 17:55 UTC (Dec 9: 7.6% no change, 61.6% one hike to 4.00%–4.25%, 30.8% two hikes).

If inflation ran hot (core 0.3% or more): the market had already priced a hike by December; a hot core print brings that hike closer to October and strengthens officials such as Cleveland Fed President Beth Hammack, who argued on October 12 that a restrictive stance is needed (see our report: Hammack calls for restrictive policy as the 10-year yield holds above 5%).
If core came in at 0.2% or below: a headline print driven by energy gives the Committee room to hold in October and wait for the December projections.
What happened: core came in hot. The probability of a 25 bp hike on October 28 rose from 21.6% to 34.9%, and the odds of two hikes by December 9 rose from 18.7% to 30.8%. A hold in October remains the base case; no cut is priced at either meeting.

Last month's template: after the August CPI on September 11 (headline 0.4%, core 0.3%), Bitcoin rose from about $77,000 at 12:00 UTC to about $79,160 at 14:00 UTC, or +2.8% in two hours on CoinGecko's hourly data, before giving back part of the gain in the afternoon.
ETF demand was already weak: US spot Bitcoin ETFs recorded $451.7 million of net outflows from October 1 to October 12, including −$484.9 million on October 7, according to Farside Investors. On October 13 flows turned positive (+$175.7 million, led by FBTC +$103.1 million and IBIT +$65.9 million), bringing the month to −$276.0 million and cumulative net inflows since launch to about $57.3 billion. October 14 flows: not yet published by Farside at the time of writing (see the daily Bitcoin ETF flows tracker).
Today's move: Bitcoin dropped about 1.1% within five minutes of the release and did not recover. At 17:45 UTC it traded at $81,717, 2.4% below its 8:30 a.m. ET level and close to its session low of about $81,585 (16:00 UTC). That is the opposite of September 11, when BTC gained 2.8% in two hours after the August report.

FAQ

What was the US inflation rate in September 2026?

Consumer prices rose 3.7% year over year in September 2026, after 3.4% in August, according to the Bureau of Labor Statistics. Core inflation was 2.6%, up from 2.4%.

Was September CPI higher than expected?

Partly. Headline CPI matched the 0.6% monthly forecast, but the annual rate (3.7%) beat the 3.6% consensus and core CPI beat on both measures (0.3% and 2.6%). Economists expected 0.6% month over month and 3.6% year over year for headline CPI, and 0.2% and 2.5% for core CPI.

Will the Fed raise rates on October 28?

Nobody knows before the vote. After the CPI release, CME FedWatch put the probability of a 25 bp hike at 34.9%, against 21.6% the day before. The current target range is 3.75% to 4.00%.

Why does CPI move Bitcoin?

Inflation data changes expectations for Fed policy. Higher expected rates raise the return on cash and Treasury bills and the value of the dollar, which tends to weigh on assets that pay no yield, such as Bitcoin. Lower-than-expected inflation usually works the other way. The effect is often strongest in the first hours after the 8:30 a.m. ET release.

When is the next CPI report?

The BLS will publish October 2026 CPI on November 10, 2026, at 8:30 a.m. ET.
