July Inflation US - Annual
I think a July CPI print at 3.1% or below is possible but still unlikely. The most recent data and nowcasts point to cooling inflation, but not enough cooling to make a sub-3.1% result the base case.
Analysis
The starting point is June CPI at 3.5% year over year, which is still meaningfully above the 3.1% threshold. To get to 3.1% in July, inflation would need to fall by four tenths in a single month on a year-over-year basis, which is a large move for an annual CPI measure and usually requires a favorable combination of soft monthly price gains and strong base effects. The recent information flow does show inflation easing, but the easing visible so far does not clearly imply a drop that large in the official CPI series.
The best argument for a Yes outcome is that the July comparison could benefit from base effects if July 2025 was a relatively firm month for prices, and a weak July 2026 monthly CPI reading could pull the annual rate down faster than expected. Some nowcasting signals suggested headline inflation around the low 3.3% area, which is directionally closer to the threshold than the June reading. If energy, shelter, and core services all softened together in July, it is at least plausible that the annual rate could surprise on the downside.
Against that, the available evidence still points more strongly to a reading above 3.1%. June CPI at 3.5% and June PCE at 3.7% indicate inflation was cooling, but not rapidly enough to make sub-3.1% the default expectation. The market price also reflects this, with the Yes side at only 2%, implying that informed traders see the threshold as a tail outcome. The most likely result is that July CPI edges down modestly, perhaps into the low 3% range, but stops short of 3.1% or lower.
Arguments
For
- Arguments for Yes: A favorable base effect from July 2025 combined with a soft July 2026 monthly CPI reading could pull the annual rate down more than expected.
- Arguments for Yes: If disinflation broadens beyond goods into shelter and services, the official CPI could surprise below the consensus range.
Against
- Arguments against Yes: The latest confirmed CPI reading is 3.5%, so the threshold requires an unusually large decline in just one month.
- Arguments against Yes: Market pricing and the available nowcast both imply a result above 3.1% is far more likely than a sub-threshold print.
Key drivers
- The June CPI starting point was 3.5%, so the market needs a fairly large one-month year-over-year drop to reach 3.1%.
- Recent nowcasts and easing inflation trends support further cooling, but the expected pace still appears closer to the low 3.3% area than to 3.1%.
Risk factors
- A sharp drop in shelter, energy, or core goods prices could push the annual CPI below expectations.
- A stronger-than-expected July monthly CPI increase would keep the annual rate above 3.1% and make the Yes outcome fail quickly.
Scenarios
Best case
July CPI benefits from strong base effects and weak monthly price growth, producing a surprise decline to 3.1% or lower and triggering the Yes outcome.
Most likely
Inflation continues to ease gradually from June but not enough to clear the threshold, with July CPI landing above 3.1% and most likely somewhere around the low 3% area.
Worst case
Inflation remains sticky in shelter or services, keeping July CPI near the low-to-mid 3% range or above and leaving the market firmly in No territory.
