The consensus read on the latest Producer Price Index data is that falling energy prices are doing the inflation-fighting work. The PPI services revision for July argues the underlying picture is considerably less comfortable than that framing suggests.
The headline number for the PPI final demand, which tracks prices that companies pay each other, edged down 0.03% in July from June, or an annualised -0.3%, according to data reported by the Bureau of Labour Statistics. Energy dragged it lower: the PPI for energy plunged 3.1% month-on-month in July, its second consecutive monthly decline after three months of spikes. Year-over-year, the energy PPI remains up 17.9%, so the base is still punishing, but the near-term direction gave the headline figure cover.
The problem is what happened to June once the BLS finished revising it.
The PPI Services Revision for July Buries the Lead
A month ago, the BLS reported that the June services PPI rose 0.21% from May. The revised figure, published alongside the July data, more than doubled that reading to +0.47%. The services PPI accounts for 68% of overall PPI final demand, it is, as Wolf Street put it, the biggie. Doubling a month’s services inflation in a single revision is not a rounding error; it is a material restatement of where underlying price pressure actually sat.
The same pattern showed up in core PPI. The June core reading was revised from the originally reported +0.20% to +0.39%, nearly doubling, which annualises to +4.8%. Year-over-year, core PPI now sits at 4.2%, with the four months of April through July representing the worst run since January-February 2023. The December 2023 low is increasingly looking like the trough of a new upward zigzag, not the start of a clean disinflationary trend.
Within services, trade services (which accounts for 19% of overall PPI) inched up just 0.1% in July. But June’s trade services number was revised from an originally reported +0.4% spike to a +1.4% spike. That is the kind of revision that changes the narrative around a month’s data entirely, and it arrived quietly, embedded in a release whose headline was busy pointing at falling energy prices.
Transportation PPI: The Short-Term Energy Effect and the Longer Trend
The transportation component gives the energy story its most legible transmission mechanism. The PPI for transportation and warehousing services plunged 1.8% month-on-month in July, its second consecutive decline, directly tracking the slide in energy prices. Truck transportation of freight fell 1.8% on the same basis. Energy costs weigh heavily in transport operations, so a two-month energy pullback does flow through. The question is whether it persists.
The longer context complicates the near-term relief. According to the Bureau of Labour Statistics, producer prices for trade services rose 4.4% across full-year 2024, while transportation and warehousing services rose 2.1% over the same period. Those are the structural baselines against which any single month of energy-driven softness should be assessed. A 1.8% monthly dip in freight transport does not erase a 2.1% annual gain in its category, and it certainly does not address the trade services component, which has been running considerably hotter.
The Bureau of Transportation Statistics adds a further wrinkle: prices for freight transportation and equipment rose 1.9% in July 2025 from July 2024. The year-over-year comparison in transport is still positive, even after two months of monthly declines. The monthly softness is real; the trend is not yet broken.
Elsewhere in the July data, food PPI fell 0.93% month-on-month, its second consecutive decline, and is unchanged year-over-year. The “other services” category, which accounts for 38% of overall PPI, rose 0.6% in July from June. The overall PPI year-over-year reading came in at 4.7%, lower than the 5.5%-5.9% range recorded in the prior three months but still elevated. The services PPI rose 3.9% year-over-year, a deceleration from the upwardly revised June reading, though that revised reading is now the comparison point, which makes the deceleration look somewhat less reassuring than it first appeared.
The BLS’s next PPI release will tell us whether July’s services number holds, gets revised upward like June’s did, or softens further. On the current pattern, the revision line deserves as much attention as the headline.
