The simple version

The figure released this morning tracks the prices domestic sellers receive for what they sell. Most people know there is a core version with foods and energy stripped out.

There is a second, stricter core version, and it removes a third thing called trade services. That piece is worth knowing about because it does not measure what anything costs.

For a firm that buys goods and resells them untouched, the agency records the gap between what the firm paid and what it charged. What such a firm is treated as supplying is the resale service, not the goods themselves.

The numbers

• The Producer Price Index for final demand increased 1.3 percent in September, seasonally adjusted, after 0.5 percent in August and 0.2 percent in July (Bureau of Labor Statistics, Producer Price Indexes, September 2026, USDL 26-1576, released October 15, 2026)
• The release states the September increase is the largest advance since a 1.7 percent rise in March 2022 (same release)
• On an unadjusted basis the index for final demand climbed 6.3 percent for the 12 months ended in September, which the release calls the largest 12-month increase since 6.4 percent in December 2022 (same release)
• Final demand less foods and energy rose 0.7 percent in September, seasonally adjusted, and 5.0 percent over the 12 months ended in September (same release, Table 1)
• Prices for final demand less foods, energy, and trade services moved up 0.5 percent in September after 0.3 percent in August, and 5.0 percent over the 12 months ended in September (same release)
• Prices for final demand goods advanced 2.6 percent, which the release calls the largest increase since data were first calculated in December 2009, and over 80 percent of that rise is attributable to final demand energy, which jumped 10.8 percent (same release)
• Final demand foods advanced 1.2 percent and final demand goods less foods and energy advanced 0.3 percent (same release)
• Prices for final demand services moved up 0.8 percent, and the release attributes nearly half of that increase to a 1.4 percent rise in margins for final demand trade services (same release)
• The agency's methodology states that it views wholesalers and retailers as suppliers of distributive services rather than goods, and tracks the average changes in gross margins they receive (BLS, Handbook of Methods, Producer Price Indexes, Concepts)

Why one of the pieces is not measuring an item

A firm that buys goods and resells them untouched is not making anything. The agency's published method treats what it supplies as a service, and sets out the activities it has in mind.

So for those firms the measured amount is the difference between what they charged and what they paid. When that gap widens the series rises, even if nothing anywhere changed hands at a different figure.

That is why there are two core versions rather than one. Taking out foods and energy removes the jumpy goods. Taking out trade services as well removes the one piece that answers a different question from the rest.

Neither version is the honest one and neither is a trick. They answer different questions, and the agency publishes both precisely so a reader can tell them apart.

The actual math on 1.3 and 0.5

Put the two September figures side by side. The headline moved 1.3 percent and the version with foods, energy and trade services removed moved 0.5 percent.

The agency does the attribution itself rather than leaving it to arithmetic. Over 80 percent of the goods rise was energy, which jumped 10.8 percent. Nearly half of the services rise was a 1.4 percent move in trade services.

Those are the release's own attributions, not our arithmetic, and that matters. The headline and the stricter version are separately weighted aggregates, so the space between them is not something a reader can take apart by removing one from the other.

What a reader can take from it is the ordering. The broad figure moved more than twice as far as the one with the jumpy goods and the resale series removed.

What this means

When a headline says producer costs jumped, the useful follow-up is which version moved and what the agency says drove it. Both are in the release and neither requires any arithmetic.

The trade services piece also explains something that otherwise looks strange. A month where resellers widen the gap between buying and selling shows up as a rise in a measure most people read as a cost, which it is not.

The practical habit is to read the stricter version alongside the headline rather than instead of it. One tells you what sellers received across the board. The other tells you what is left after the pieces that answer a different question are set aside.

What this is NOT

This article explains that the producer price release carries two different core measures and what the trade services component actually tracks, using the Bureau of Labor Statistics Producer Price Indexes release for September 2026, USDL 26-1576, and the agency's Handbook of Methods chapter on producer price concepts, both read on October 15, 2026. It is not a forecast of consumer prices, producer prices, interest rates, or any Federal Reserve decision, and it does not claim that producer figures predict consumer figures on any timetable. It is not advice about any purchase, loan, security, or fund, and it is not a claim that the agency measures anything incorrectly: treating resellers as suppliers of distribution is published methodology with a stated rationale, which this article describes rather than disputes. It states no figure of its own: every number here is the release's, and the attributions of the goods rise to energy and of the services rise to trade services margins are the release's own, not our calculation. It deliberately does not subtract one aggregate from the other, because they are separately weighted and that subtraction would not mean what it appears to mean. It is not a statement about whether any seller's markup is too high or too low. This is not a political endorsement or criticism of anyone.
