## Analysis

## TL;DR
My modal forecast is a 4.0% June headline CPI-U print, with 31.5% on 4.0% and 30% on 3.9%.
The center is just below 4.0% unrounded because the [May CPI-U index](https://www.bls.gov/news.release/cpi.htm?lv=true) was high but [gasoline fell sharply in June](https://www.eia.gov/dnav/pet/pet_pri_gnd_a_epm0_pte_dpgal_w.htm).
Most of the mass sits from 3.8% through 4.1%, and values above 4.3% need a late energy reversal before the [July 14 release](https://www.bls.gov/schedule/news_release/cpi.htm).

## Context
The target is the BLS all-items CPI-U, not seasonally adjusted, 12-month percent change for June 2026, as printed in the July CPI news release. The release is scheduled for Tuesday, July 14, 2026, at 8:30 a.m. ET on the [BLS CPI release calendar](https://www.bls.gov/schedule/news_release/cpi.htm).

The last official CPI observation is May 2026. BLS reported May CPI-U NSA at 335.123, headline CPI up 4.2% over 12 months, headline CPI up 0.5% seasonally adjusted on the month, core CPI up 2.9% over 12 months, energy up 3.9% seasonally adjusted on the month, and gasoline up 7.0% seasonally adjusted and 8.6% not seasonally adjusted on the month in the [May CPI release](https://www.bls.gov/news.release/cpi.htm?lv=true).

## Evidence
The historical backbone is May-to-June NSA seasonality in CPI-U all items. I use the modern 2010-2025 window, N=16 monthly May-to-June changes, from current-vintage [FRED CPIAUCNS](https://fred.stlouisfed.org/series/CPIAUCNS), source BLS, last updated June 10, 2026. The mean was +0.286%, the median was +0.213%, and the range was -0.147% to +1.374%. That base rate alone would point above 4.0%, but 2026 is not a normal June because gasoline is falling after the May spike.

| Year | May CPI-U NSA | June CPI-U NSA | May-to-June NSA change |
|---:|---:|---:|---:|
| 2010 | 218.178 | 217.965 | -0.098% |
| 2011 | 225.964 | 225.722 | -0.107% |
| 2012 | 229.815 | 229.478 | -0.147% |
| 2013 | 232.945 | 233.504 | +0.240% |
| 2014 | 237.900 | 238.343 | +0.186% |
| 2015 | 237.805 | 238.638 | +0.350% |
| 2016 | 240.229 | 241.018 | +0.328% |
| 2017 | 244.733 | 244.955 | +0.091% |
| 2018 | 251.588 | 251.989 | +0.159% |
| 2019 | 256.092 | 256.143 | +0.020% |
| 2020 | 256.394 | 257.797 | +0.547% |
| 2021 | 269.195 | 271.696 | +0.929% |
| 2022 | 292.296 | 296.311 | +1.374% |
| 2023 | 304.127 | 305.109 | +0.323% |
| 2024 | 314.069 | 314.175 | +0.034% |
| 2025 | 321.465 | 322.561 | +0.341% |

The arithmetic is tight. The June 2025 denominator is 322.561 and the May 2026 numerator is already 335.123 in current-vintage [FRED CPIAUCNS](https://fred.stlouisfed.org/series/CPIAUCNS). A flat June index gives 3.895% year over year, which rounds to 3.9%. A 4.0% print needs only +0.053% to +0.150% May-to-June NSA inflation, while a 4.1% print needs +0.150% to +0.246%.

| Printed value | Unrounded YoY band | Implied May-to-June NSA band |
|---:|---:|---:|
| 3.8% | 3.75% to under 3.85% | -0.139% to under -0.043% |
| 3.9% | 3.85% to under 3.95% | -0.043% to under +0.053% |
| 4.0% | 3.95% to under 4.05% | +0.053% to under +0.150% |
| 4.1% | 4.05% to under 4.15% | +0.150% to under +0.246% |
| 4.2% | 4.15% to under 4.25% | +0.246% to under +0.342% |

Gasoline is the main current-month signal. EIA all-grades all-formulations retail gasoline, U.S. average, dollars per gallon, averaged $4.609 across the four May 2026 weekly observations and $4.302 across the first three June 2026 observations, a 6.65% fall through June 15 in the [EIA weekly gasoline series](https://www.eia.gov/dnav/pet/pet_pri_gnd_a_epm0_pte_dpgal_w.htm). AAA's daily regular national average then fell to $3.938 on June 21, from $4.074 one week earlier and $4.564 one month earlier, on the [AAA fuel price page](https://gasprices.aaa.com/?lv=true). BLS says gasoline CPI uses daily secondary-source data, monthly gasoline indexes are calculated from daily datasets, and CPI motor fuel corresponds to average prices over a calendar month rather than a single weekly EIA observation in the [BLS motor fuel methodology note](https://www.bls.gov/cpi/factsheets/motor-fuel.htm). That makes the post-June 15 slide relevant.

| Week | EIA all-grades gasoline, $/gal |
|---|---:|
| 2026-05-04 | 4.581 |
| 2026-05-11 | 4.628 |
| 2026-05-18 | 4.621 |
| 2026-05-25 | 4.605 |
| 2026-06-01 | 4.439 |
| 2026-06-08 | 4.281 |
| 2026-06-15 | 4.187 |

The offsets are real. Gasoline had 3.937% relative importance, energy 7.474%, food 13.512%, and all items less food and energy 79.014% in the [May CPI release](https://www.bls.gov/news.release/cpi.htm?lv=true). The Cleveland Fed's June 18 nowcast put June CPI at +0.02% month over month and +4.01% year over year, with core CPI at +0.23% month over month and +2.85% year over year, on the [Cleveland Fed inflation nowcasting page](https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting). I treat that as the best single non-market anchor, but I move modestly below it because AAA and EIA show gasoline continuing to fall after the last full EIA week that the nowcast could use.

My final distribution is centered near a +0.06% to +0.07% May-to-June NSA CPI move, or just under 4.0% unrounded year over year. The printed-value probabilities are 31.5% for 4.0%, 30% for 3.9%, 16.5% for 4.1%, 13.5% for 3.8%, 4.5% for 4.2%, and 2.5% for 3.7%, with about 1.1% on 4.3% or higher. This gives 59.0% on 3.9% or 4.0% combined.

## What's non-obvious
The May 4.2% headline is a poor guide to the June print. The June 2025 base was already a firm month, so a flat June 2026 CPI-U index mechanically falls to 3.895% year over year using [FRED CPIAUCNS](https://fred.stlouisfed.org/series/CPIAUCNS). The fight is not whether energy is still high versus last year. It is whether June 2026's all-items index rises more than about 0.053% from May.

The second edge is timing. BLS gasoline CPI is built from daily gasoline data across the month, while EIA's public gasoline series is weekly and AAA's headline is daily, as described in the [BLS motor fuel methodology note](https://www.bls.gov/cpi/factsheets/motor-fuel.htm). The June 21 AAA price is too late to dominate the whole month, but it is not irrelevant. It pulls the center down from the Cleveland Fed's 4.01% nowcast toward the 3.9%-4.0% boundary.

## Limitations
The biggest missing input is the final nine days of June gasoline data. EIA's official weekly all-grades gasoline data available now run only through June 15 in the [EIA weekly gasoline series](https://www.eia.gov/dnav/pet/pet_pri_gnd_a_epm0_pte_dpgal_w.htm), while AAA is timelier but is not the same object as BLS gasoline CPI in the [AAA fuel price page](https://gasprices.aaa.com/?lv=true). Core services and shelter can also move the rounded print by one tenth because core is about four-fifths of the basket in the [May CPI release](https://www.bls.gov/news.release/cpi.htm?lv=true). The geopolitical upper tail is still live: AP reported on June 21 that Iran claimed the Strait of Hormuz was closed again while U.S. Central Command said traffic continued, including 55 merchant ships and more than 17 million barrels of oil, in the [AP June 21 report](https://apnews.com/article/39f9632b4df3a61a07a2c271da1d5637).

## Question Details

The Bureau of Labor Statistics' Consumer Price Index for All Urban Consumers (CPI-U) is the headline US inflation gauge. The 12-month change in the not-seasonally-adjusted all-items index is the figure most commonly cited as the 'inflation rate' and is reported in the BLS CPI news release in the 'Over the Last 12 Months' line. The February-2026 outbreak of the Iran war disrupted Middle East oil exports, pushing US retail gasoline from under $3/gal pre-war to $4.11/gal by mid-April 2026. This drove a 0.9% MoM headline CPI jump in March (released 2026-04-10) and lifted year-over-year headline inflation to 3.3%, the highest since May 2024. Core CPI (ex food and energy) rose more modestly to 2.6% YoY. The Cleveland Fed's inflation nowcast for April 2026 climbed from 3.28% at month-start to 3.58% by April 15. Whether June 2026 prints higher, flat, or lower than March depends largely on the path of crude and gasoline prices over the next ~10 weeks (which in turn depends on the Iran-war trajectory and any OPEC+ response), pass-through of energy into transportation/food, and core services dynamics including shelter. Long-range projections ahead of the next prints cluster in the 3.2–3.6% range for June, with meaningful tail risk in both directions. The June 2026 CPI release is scheduled for the second week of July 2026 per the BLS release calendar.

### Resolution Criteria

Resolves to the 'Unadjusted 12-months ended Jun. 2026' percent change in the All items CPI-U index, as reported in the BLS Consumer Price Index news release covering data for June 2026 (publication scheduled July 2026). Primary source: the BLS CPI news release page at https://www.bls.gov/news.release/cpi.htm and the corresponding PDF (Table A or the 'Percent change Unadjusted 12-months ended' column for All items). The reported figure (rounded to one decimal as published by BLS) is the resolution value. Use the value from the original release; subsequent annual revisions do not change the resolution.

### Fine Print

Use the headline All-items CPI-U not-seasonally-adjusted 12-month percent change exactly as printed in the BLS news release. If BLS delays the June 2026 release past 31 August 2026, resolution waits for publication. If BLS reports the value to a different precision than one decimal, use the value as printed and round to one decimal using standard rounding. Do not use Core CPI, CPI-W, chained CPI, or PCE; do not use seasonally adjusted year-over-year figures.
