Final-demand goods prices rose by the most since the series began in 2009, with gasoline up 20%. The more durable signal may be in services, where trade margins and transportation costs climbed, and in a pipeline of intermediate goods running 14% above last year.
September's 1.3% rise in producer prices is easy to blame on oil. The details show something harder to dismiss.
Prices for final-demand goods rose 2.6% in the month, the largest increase since the Labor Department began calculating the figure in December 2009. More than 80% of that came from energy, which jumped 10.8%. Gasoline alone rose 20.3% and accounted for half of the goods increase. Food rose 1.2%. Goods excluding food and energy rose only 0.3%.
On that evidence, September looks like an energy shock passing through.
The services side
Services tell a different story. Final-demand services prices rose 0.8%, the most since April. Nearly half of that came from trade services, which measure the margins wholesalers and retailers earn, up 1.4%. Transportation and warehousing prices rose 3.4%.
A rise in trade margins means sellers raised their prices by more than their own costs went up. That is the opposite of what usually happens early in an energy shock, when distributors absorb part of the increase. One channel did absorb it: margins for automotive fuel retailing fell 30.3%. Elsewhere, sellers passed costs on and widened their margins in the process.
A narrower measure that strips out food, energy and trade services rose 0.5% in September after 0.3% in August, and is up 5.0% from a year earlier.
The pipeline
Further up the supply chain, pressure is building. Processed goods for intermediate demand, the materials and components businesses buy from one another, rose 2.5% in the month and 14.1% over 12 months, the fastest annual pace since August 2022. Unprocessed goods rose 8.4% in September and 21.5% over the year, led by a 22.2% increase in energy materials. Services for intermediate demand rose 6.3% from a year earlier, the most since January 2023.
Factories are planning to pass more of it on. In the Philadelphia Fed's October manufacturing survey, the index of prices that firms receive rose to 40.1, the highest since May 2025, even as the overall activity index fell to 20.9 from 37.8 and new orders slowed sharply.
The gap with consumer prices
Producer prices are up 6.3% from a year earlier. Consumer prices, reported Wednesday, are up 3.7%. That 2.6-point gap is the question for the coming months: either consumer prices catch up as wholesale costs feed through, or producers' margins compress when energy eases.
Market implications
One reading is that this is an energy pulse that will reverse with oil. Energy explains most of the goods surge, core goods prices rose only 0.3%, and fuel retailers' margins were crushed, a sign that part of the shock is being absorbed rather than passed along.
A second reading is that pass-through is already underway. Trade margins and freight costs rose sharply, intermediate goods are up 14% in a year, and manufacturers are reporting higher selling prices. For a Fed weighing whether the energy shock will fade on its own, the services detail is the harder number to wave away.
What to watch
October's consumer-price report on Nov. 10 will show whether goods prices outside energy start rising faster. Retailers' and distributors' third-quarter margin commentary over the next three weeks will show whether the trade-margin jump reflects pricing power or a one-month quirk.
