PPI YoY - August 2026
The most recent PPI reading shows meaningful cooling, but not enough to make 4.2% or lower the most likely August outcome. I think the threshold is still a long shot, though slightly more plausible than the market price suggests.
Analysis
The latest official reading is July headline PPI at 4.7% year over year, down sharply from 5.5% in June and accompanied by a flat monthly print. That is a clear sign of easing producer inflation momentum, but it still leaves the index materially above the 4.2% threshold for this market. To resolve Yes, August would need another notable step down, not just a small improvement.
The key mechanical issue is that year-over-year PPI is very sensitive to the comparison base and to one month of monthly inflation. A flat July helped the annual rate fall, but getting from 4.7% to 4.2% in one additional month usually requires either a weak August 2026 monthly reading, a favorable August 2025 base, or both. Because this market uses the headline final demand measure, any rebound in energy, goods, or services inflation could easily keep the annual figure above the cutoff.
Market sentiment also leans strongly against Yes, with the listed probability for 4.2% or lower far below 10%. That makes sense because the recent cooling was encouraging but not dramatic enough to imply a clean break to sub-4.2% territory. Still, there is some tail risk on the downside if August producers saw another broad-based soft month, especially if commodity and transportation costs eased further. I view that as possible but not the base case, so the Yes outcome deserves only a small single-digit probability.
Arguments
For
- Arguments for Yes: The latest trend is clearly downward, so another cooling month could push the annual rate to 4.2% or lower.
- Arguments for Yes: If August 2025 was a relatively firm base month, even a neutral August 2026 reading could produce a larger year-over-year decline than expected.
Against
- Arguments against Yes: Headline PPI is still at 4.7%, so the market needs a fairly large one-month drop to clear the 4.2% line.
- Arguments against Yes: The most recent month was flat rather than negative, which suggests moderation but not enough deflationary momentum to make Yes likely.
Key drivers
- July’s sharp drop and flat monthly PPI show that producer inflation has been cooling, which keeps a lower August print within reach.
- The annual comparison can move quickly if August 2025 had a strong base and August 2026 monthly prices were soft or negative.
Risk factors
- A modestly positive August monthly PPI reading would likely leave the year-over-year rate above 4.2%.
- Services or energy inflation could rebound enough to offset the July slowdown and keep headline PPI elevated.
Scenarios
Best case
Producer prices soften again in August, driven by weaker energy and goods categories, and the year-over-year headline rate falls to 4.2% or below on the BLS release.
Most likely
The August report shows further moderation from July but not enough of a drop to reach 4.2%, leaving the final reading somewhere above the cutoff, likely in the mid-4% area.
Worst case
August sees renewed price pressure in services or energy, keeping headline PPI around the mid-4% range or higher and decisively failing the threshold.

The combination of an already very large base and guidance for 600 to 650 net new global openings makes the threshold look attainable unless closures or execution slippage are unusually heavy.

Where will 2026 rank among the hottest years on record?
AI28%MKT74%Edge-46Hyped2026 is likely to finish as another exceptionally warm year, but I think the chance that it ends up as the single hottest year on record is materially lower than the market implies. The main reason is that the strongest record-setting years usually benefit from a strong El Niño-type boost, and 2026 does not currently look like it has that same tailwind.
