The consensus read on US producer price inflation is that it remains an uncomfortable but slowly resolving legacy of the pandemic era. The August data from the Bureau of Labor Statistics makes that reading hard to sustain.
Overall PPI Final Demand rose by 5.4% year-over-year in August, and on a month-to-month basis climbed 0.40%, equivalent to 5.0% annualised. The July figures were revised higher. This is not a one-month blip: the index has been zigzagging upward since its low point in mid-2023, a trajectory that has now extended long enough to stop looking like noise.
Where US Producer Price Inflation Is Actually Accelerating
The services PPI, which accounts for 68% of the overall PPI Final Demand, rose 4.5% year-over-year in August, with its July reading also revised upward. Within services, the transportation and warehousing PPI spiked 10.3% year-over-year and 1.2% month-to-month, the latter equivalent to 15.1% annualised. That is not a rounding error.
Core PPI Final Demand, stripping out energy and food, rose 4.6% year-over-year and has been trending higher since January 2024. Core goods PPI rose 5.0% year-over-year, a level it has now held for four months, its highest reading since February 2023. Energy PPI spiked 24.3% year-over-year and 4.16% month-to-month, the latter annualising to 63%. Food was the one soft patch, up just 0.1% year-over-year, after a 36% cumulative surge from mid-2020 through February 2025 left prices effectively range-bound.
The GDP price deflator, which captures inflation across consumers, businesses, non-profits and governments, spiked 6.4% annualised in Q2 from Q1, and 4.4% year-over-year, and was also revised higher. That figure does not show up in the PPI or CPI headlines, but it is the broadest measure of economy-wide price pressure available, and it is running hot.
The Tariff Complication the Disinflation Narrative Had Not Priced In
Here is the part the disinflation story struggles with. Inflation did come close to something resembling normal: according to the New York Times, it fell to 2.3% in April 2025. That was the moment when the soft-landing narrative looked most credible. It did not last.
President Trump imposed sweeping tariffs on US trading partners, which, the New York Times reports, pushed up the cost of many imported goods. The producer price data showing up now reflects, at least in part, that cost pass-through working its way through supply chains. The core goods PPI at 5.0% year-over-year, holding that level for four months, is consistent with tariff-driven input cost pressure that has not yet exhausted itself. The transportation and warehousing spike reinforces that reading: higher fuel and logistics costs are precisely the kind of second-order effect tariffs generate.
The popular framing treats US producer price inflation as a lagging residual. The data suggests it may instead be a leading indicator of a second inflation episode, with a different set of causes than the first. Pandemic-era supply disruptions were always likely to resolve. Tariff-driven cost structures are a policy choice, and policy choices do not unwind on their own timetable.
The 12 voting members of the FOMC, chaired by Warsh, face a straightforward question that the soft-landing narrative has been quietly deferring: at what point does the rate path reflect what the data actually shows? Wolf Street has argued directly that the Fed needs to stop waiting and vote for rate hikes. The argument is not subtle, but then neither is a core goods PPI at 5.0% for four consecutive months.
The Consumer Price Index release is due the following day. If it prints in the same direction, the deferral gets harder to justify. The GDP deflator already revised higher. The PPI revised higher. The pattern is there; what is missing is a policy response that acknowledges it.
