U.S. Producer Prices Surge 1.3% in September, Biggest Monthly Increase Since 2022

U.S. producer prices rose 1.3% in September, the biggest monthly increase since March 2022, as a sharp jump in energy costs pushed wholesale inflation noticeably higher after a steadier summer. On an unadjusted basis, the Producer Price Index for final demand was up 6.3% from a year earlier, the strongest 12-month increase since December 2022.

The September move followed gains of 0.5% in August and 0.2% in July. That sequence matters because it shows price pressures picking up again after a slower stretch, with the latest increase broad enough to extend beyond one volatile category. Producer prices track what domestic sellers receive for their output, so the report is often watched for clues about cost pressures moving through the supply chain.

In its September Producer Price Index release, the U.S. Bureau of Labor Statistics said final-demand goods prices rose 2.6% and final-demand services prices advanced 0.8%. A core measure that excludes food, energy and trade services also increased 0.5% in September, after a 0.3% rise in August, suggesting that the month’s inflation pulse was not limited to fuel alone.

Energy and gasoline drove the headline jump

The goods side of the report accounted for much of the surprise. Final-demand goods prices climbed 2.6% in September, the largest increase since that series was first calculated in December 2009. More than 80% of the broad-based gain came from final-demand energy, which jumped 10.8% during the month. Food prices also rose 1.2%, while prices for goods excluding food and energy increased a milder 0.3%.

Gasoline was the clearest single driver. BLS said half of the September increase in the final-demand goods index could be traced to a 20.3% jump in gasoline prices. Diesel fuel, jet fuel, residential electric power and crude petroleum also moved higher. Some categories moved the other way, including chicken eggs, which fell 39.7%, along with thermoplastic resins and commercial electric power. Even with those offsets, the overall picture was one of broad upward pressure in goods prices, especially across energy-related items.

The annual comparison also shows how much the pace has accelerated. Final-demand prices were up 6.3% from September 2025, the largest 12-month increase since prices rose 6.4% in December 2022. That does not mean every category is behaving like it did during the earlier inflation spike, but it does show that wholesale inflation has moved back into a range that policymakers and businesses cannot easily dismiss as statistical noise.

Services and the core gauge also firmed

The report was not only about gasoline. Final-demand services prices rose 0.8% in September, matching the largest monthly increase since April. Nearly half of that increase came from a 1.4% rise in margins for final-demand trade services, a category that measures changes in margins received by wholesalers and retailers rather than the sticker prices of the goods they sell. Transportation and warehousing services rose 3.4%, and services excluding trade, transportation and warehousing increased 0.3%.

Within services, BLS said more than one-fifth of the September increase could be traced to margins for machinery and vehicle wholesaling, which rose 3.9%. Truck transportation of freight, food and alcohol wholesaling, traveler accommodation services, food retailing and airline passenger services also moved higher. That mix is important because it points to cost pressure in several parts of the service economy rather than in one narrow corner.

The cleaner underlying measure also strengthened. Prices for final demand less foods, energy and trade services rose 0.5% in September, after increasing 0.3% in August. Over the 12 months ended in September, that gauge was up 5.0%. Because it strips out some of the noisiest components, that measure is often watched as a better read on underlying pricing trends. A 0.5% monthly increase is not extreme by itself, but combined with the stronger services reading, it suggests the headline 1.3% rise cannot be written off as a purely energy-driven distortion.

Upstream price pressures broadened across the pipeline

The intermediate-demand portion of the report showed that higher prices were not confined to goods and services sold at the final-demand level. Within intermediate demand by commodity type, prices for processed goods rose 2.5% in September, unprocessed goods increased 8.4%, and services advanced 0.9%. Those readings suggest that many businesses faced firmer input costs before their goods and services reached end markets.

Processed goods for intermediate demand posted their largest increase since May. More than 80% of that advance came from a 10.2% rise in processed energy goods. Prices for processed goods were up 14.1% from a year earlier, the largest 12-month increase since August 2022. Unprocessed goods showed even sharper pressure: that index rose 8.4% in September, the largest monthly increase since February 2022, led by a 28.3% jump in crude petroleum. Over the prior 12 months, unprocessed goods prices were up 21.5%, the strongest annual increase since September 2022.

The production-flow breakdown told a similar story. Stage 4 intermediate demand, which is closest to final demand, rose 1.1% in September. Stage 3 also increased 1.1%, stage 2 climbed 3.9%, and stage 1 rose 2.2%. BLS linked those increases to higher prices for items such as gasoline, diesel fuel, grains, truck transportation and food-and-alcohol wholesaling. Put together, the stage data indicate that September’s inflation pressure showed up at several points in the production chain rather than appearing only at the very end.

What the September report says, and what it does not

The PPI does not measure the same thing as the Consumer Price Index. Producer prices capture price changes from the seller’s perspective, while consumer inflation tracks what households pay. That means a hot PPI reading does not automatically translate into an equally large rise in consumer prices. Some cost increases get absorbed in margins, some are passed through only partly, and some fade if energy markets settle back down.

Still, the September report gives inflation watchers a few concrete signals. First, energy was clearly the main force behind the headline jump, especially gasoline. Second, the gains in services and in the measure excluding food, energy and trade services suggest the inflation story was not limited to fuel. Third, the intermediate-demand data show that upstream costs also moved higher, which could matter for future pricing decisions if those pressures persist.

BLS noted that figures for May through August were revised to reflect late reports and corrections by respondents, a routine process that can slightly change the recent trend. The next key checkpoint will come quickly: the Producer Price Index for October 2026 is scheduled to be released on Friday, November 13, at 8:30 a.m. Eastern time.
