Wholesale prices rose 0.4% in August, with diesel behind more than a third of the goods increase

Producer prices in the United States rose 0.4% in August on a seasonally adjusted basis, the Bureau of Labor Statistics said in its Producer Price Index release Thursday morning, after a 0.1% increase in July. Measured over the 12 months through August and before seasonal adjustment, the index for final demand was up 5.4%.

The split beneath the headline is the part worth sitting with. Prices for final demand goods climbed 1.1% in August, while prices for final demand services rose just 0.1%. That is not a broad reflation of the American cost base; it is a goods shock working through a services economy that, on this measure, barely moved.

Energy is the engine. The BLS put the final demand energy index up 4.2% for the month, against a 0.1% rise in final demand foods. The agency is specific about how much of that traces to one fuel: "Over a third of the August increase in the index for final demand goods can be traced to prices for diesel fuel, which jumped 24.1 percent." Not everything in the complex rose — the release states that prices for residential electric power fell 0.5 percent.

Diesel is the line item that travels furthest. It is not a discretionary consumer purchase; it is an input into long-haul trucking, agricultural equipment, rail switching, marine transport and construction fleets. A move of that size shows up in freight invoices before it shows up anywhere a household would notice, which is why the producer data tends to lead the consumer data in energy-driven months rather than confirm it.

The services detail carries the same fingerprint. Truck transportation of freight rose 2.0% in August, according to the BLS. Working in the other direction, the release says margins for fuels and lubricants retailing decreased 11.3 percent — a reminder that the producer index measures margins for many trade categories, so a fast run-up in wholesale fuel costs can compress the reported price of the distribution layer even as the underlying commodity soars.

Strip out the volatile pieces and the picture calms considerably. The index for final demand less foods, energy, and trade services rose 0.3% in August, after a 0.4% increase in July, and was up 4.7% over the 12 months through August, per the BLS. That is the measure the agency discusses in the release narrative. The more familiar core reading — final demand excluding food and energy — is not written up in the release text; Charles Schwab's market update, published as of 9:22 a.m. ET Thursday, put it at 0.2% for the month and 4.6% on an annual basis, and said the headline figure was in line with consensus.

Further back in the production chain, the pressure is heavier and the same fuel is doing even more of the work. Prices for processed goods for intermediate demand rose 1.8% in August and unprocessed goods for intermediate demand rose 1.1%, the BLS said, adding that "nearly two-thirds of the August rise in the index for processed goods for intermediate demand can be traced to a 24.1-percent increase in prices for diesel fuel." For the 12 months ended in August, prices for stage 1 intermediate demand advanced 11.3%. Intermediate-demand indexes are noisier than final demand and are not a forecast of anything, but they describe what is currently sitting in the pipeline behind the finished-goods number.

A caution on how much weight this release can bear: the Federal Reserve's stated inflation objective is defined in terms of personal consumption expenditures, not producer prices. Several PPI components feed the PCE calculation — Schwab singled out airfare, transportation and warehousing as firmer lines that filter into it — which is why the report gets read closely in the hours after it lands. It remains an input to that estimate rather than a substitute for it.

The release arrived into a market already dealing with an energy move. TheStreet reported West Texas Intermediate crude up 4.2% at $100.10 a barrel and Brent up 3.6% at $105.37 as of 9:35 a.m. EDT Thursday, attributing the move to a sharp escalation in fighting between the United States and Iran, and describing oil above $100 as its highest level since May.

Rates had already moved before the data. The 10-year Treasury note yield finished Wednesday at 4.845%, up four basis points and the highest since November 2023, with the two-year at 4.436%, according to Zacks Investment Research's Sept. 10 market summary. Schwab's Thursday morning update said that "odds of a rate hike jumped to 65% from 60%, according to the CME FedWatch Tool," without naming the meeting; a Yahoo Finance report on Sept. 8 had put the same tool at nearly 56% odds of a quarter-point hike at the Sept. 16 meeting, following Federal Reserve Chairman Kevin Warsh's keynote speech at the central bank's Jackson Hole symposium. Those are market-implied probabilities from a single tool on specific dates, not a statement of what the Committee will decide.

The calendar is unusually compressed. Schwab lists the August consumer price report for Friday, Sept. 11, and the Federal Reserve's rate decision for Wednesday, Sept. 16. Under the Fed's own communications blackout convention, policymakers stay publicly quiet in the run-up to a meeting, which means the producer and consumer data are effectively the last new public information before the decision.

Equities were lower with the session still in progress. As of 9:09 a.m. EDT Thursday, TheStreet reported the S&P 500 down 0.59%, the Nasdaq down 0.97%, the Dow down 0.35% and the Russell 2000 down 1.32%. That followed Wednesday's close, when the S&P 500 finished at 7,636.36, down 0.48%; the Nasdaq Composite at 26,253.34, down 0.64%; the Dow at 52,380.66, down 0.77%; and the Russell 2000 at 2,919.86, down 1.36%.

For the rest of Thursday and into Friday, the question the producer report leaves open is narrow and answerable: whether the August energy surge stayed bottled inside goods and freight, or whether it has begun leaking into the services categories that make up the larger share of the consumer basket. The August CPI is the next document that speaks to it.
