The Bureau of Labor Statistics released the September 2026 Producer Price Index on Thursday, October 15 (8:30 a.m. ET). Wholesale prices did not cool after a hot CPI. They exploded.

Final demand rose 1.3% month-over-month — the largest increase since 1.7% in March 2022. August was revised to +0.5% (from the +0.4% first reported). Over 12 months, producer prices were up 6.3%, the fastest annual pace since December 2022. Economists had been looking for about 0.5% on the month and 5.4% over the year. This print more than doubled the monthly forecast.

It lands 12 days before the Fed’s October 27–28 meeting, and one day after September CPI hit 3.7%.

Energy did most of it — gasoline 20%, diesel in the pipeline

Final demand goods jumped 2.6%, the largest goods increase since that series began in December 2009. More than 80% of it was energy: final demand energy +10.8%. Gasoline jumped 20.3% and accounted for half of the goods advance. Diesel, jet fuel, residential electric power, and crude also rose. Foods were +1.2%. Goods excluding food and energy still rose 0.3%.

Further up the chain it was worse. Processed energy goods +10.2%. Diesel fuel for intermediate demand +21.0%. Unprocessed energy materials +22.2%. Crude petroleum +28.3%. Processed goods for intermediate demand are up 14.1% over 12 months; unprocessed goods +21.5% — both the hottest annual rates since late 2022. That is freight, chemicals, and packaging still in the warehouse, not yet fully on the shelf.

Eggs were the exception that proves the split: chicken eggs −39.7% at the wholesale level. Cheap eggs do not cancel $6 diesel.

Services were not a bystander

Final demand services rose 0.8%, matching April as the largest services month since spring. Trade margins +1.4%. Transportation and warehousing +3.4% — truck freight of the same distillate squeeze households already saw at diesel pumps. Machinery and vehicle wholesaling +3.9%. Traveler accommodation and airline passenger services also rose. Automotive fuels retailing margins collapsed 30.3% — stations eating wholesale, not a sign that fuel got cheaper.

Core did not sit this one out

PPI excluding foods, energy, and trade services rose 0.5% on the month and 5.0% over the year, up from 0.3% and 4.8% in August. Econoday’s read of PPI excluding food and energy was +0.7% MoM / +5.0% y/y, above the top of the forecast range. Headline energy explains the 1.3%. It does not explain core-core at 5%.

What this means at the pump — and in the next CPI

You do not buy the PPI. You buy gallons. September CPI already had gasoline +9.1% and energy +5.2%. Wholesale gasoline at +20.3% is the same month, one step earlier in the chain — and a tell that pass-through is not finished. Diesel at +21% in intermediate demand is how this shows up later as fuel surcharges, grocery pallets, and construction bids. Pump side: California diesel $7.91, gas tracker.

For the Fed

Chair Warsh hiked 25bp on September 16 and refused to guide the next meeting. Recap: 12–0 hike after July’s 9–3 hold. After Wednesday’s CPI, markets had about even odds of another hike on Oct 27–28. A 1.3% wholesale month that also lifts estimates of September core PCE (Wall Street now around +0.32% MoM, ~3.1% y/y, per CNBC) is not the print that lets the Committee “look through” oil. Core wholesale at 5% y/y is the second-round effect they said they were watching.

Next CPI is November 10. Next PPI is November 13. The meeting is first.

Bottom line

September PPI is the wholesale version of the CPI heat-up, only larger. 1.3% is a 2022-size month. Energy and gasoline did the damage. Services, trucking, and a 5% core-core rate mean it is not only Hormuz. If this pipeline prints through to retail, October and November CPI stay ugly even if crude takes a breath.

PPI series: February · March · August · September. Consumer side: September CPI 3.7%, CPI tracker.
