US producer prices rose 0.4 percent in August from a month earlier on a seasonally adjusted basis, matching the 0.4 percent consensus, while the 12-month rate jumped to 5.4 percent from a revised 4.8 percent in July, the fastest annual reading of 2026, the Bureau of Labor Statistics reported on Sept. 10. The annual figure landed a tenth of a point above the 5.3 percent economists had pencilled in. July's numbers were revised up in the same release: the monthly reading moved from no change to 0.1 percent, and the annual rate from 4.7 percent to 4.8 percent.
Under the surface the picture is more mixed. Core PPI, which strips out food and energy, rose 0.2 percent on the month, below the 0.3 percent forecast and slower than July's 0.3 percent, while its annual rate rose to 4.6 percent from a revised 4.3 percent. A second gauge of underlying pressure, final demand less foods, energy and trade services, advanced 0.3 percent in August after 0.4 percent in July and 4.7 percent over 12 months, unchanged from the previous reading.
Energy explained the bulk of the headline move. Final-demand energy prices climbed 4.2 percent in the month, with diesel fuel alone surging 24.1 percent, more than a third of the entire increase in final-demand goods prices. Gasoline and jet fuel also rose. Goods prices overall were up 1.1 percent, ending two consecutive monthly declines, while services added just 0.1 percent, with transportation and warehousing up 2.3 percent. Away from energy, electronic components climbed 3.4 percent in the month and 27.6 percent over the year, a byproduct of the artificial-intelligence buildout, Capital Economics chief North America economist Stephen Brown said.
Pressure further up the supply chain was steeper. Processed goods for intermediate demand rose 1.8 percent in August and 11.5 percent over 12 months, while unprocessed goods for intermediate demand gained 1.1 percent on the month and 12.8 percent on the year. The portfolio management index, watched closely because it feeds directly into the personal consumption expenditures deflator, slipped 1.6 percent in the month but remains 18.8 percent above its year-earlier level.
Why it matters
The report lands six days before the Federal Reserve concludes its Sept. 15-16 meeting and one day before August consumer price data. Market pricing moved immediately: the probability of a rate hike at the meeting rose to 70 percent from 64 percent after the release, according to CME FedWatch data cited by CNN. investingLive, which tracks fed funds futures, stood at 64 percent in its mid-morning reading and flagged a stronger dollar. Treasury yields rose and stock futures fell, Quartz reported, as Brent crude raced above $105 a barrel for the first time since late May. Fed Governor Christopher Waller has said stubborn inflation would push him to "consider a rate hike" even though he would otherwise favour holding. The Fed's inflation target is 2 percent.
The ECB tightens on the same day
The European Central Bank's Governing Council also raised its three key rates by 25 basis points: the deposit facility rate rises to 2.50 percent, the main refinancing rate to 2.65 percent and the marginal lending rate to 2.90 percent, effective Sept. 16. "The conflict in the Middle East continues to generate inflation pressures, and inflation is set to remain well above target for an extended period," the Frankfurt statement said, confirming a meeting-by-meeting approach. The move had been widely expected: euro-area inflation has climbed to 3.3 percent, the highest in three years, with energy the main driver. For markets the picture is one of simultaneous tightening on both sides of the Atlantic, with the energy shock as the common cause; ANSA reported that the verdict on a US hike could arrive as early as Friday's inflation data.
Central bank week
The decisive appointment is the FOMC meeting on Tuesday, Sept. 15 and Wednesday, Sept. 16. The Bank of England follows on Thursday, Sept. 17: Bank Rate has been unchanged at 3.75 percent since July 30 and markets price no move, with UK inflation at 2.9 percent. The Bank of Japan closes the sequence on Sept. 17-18, with a 25 basis point increase to 1.25 percent seen as likely by traders.
All of this comes as Kevin Warsh's Federal Reserve has abandoned forward guidance: in his Aug. 28 Jackson Hole keynote, the chairman said he wanted to change the "form and function" of guidance on the future path of rates, urging market participants to draw their own conclusions from the data. Without an official steer, each statistical release carries more weight — and Friday's CPI is the last piece before the decision.
What the data do not show
One month is not a trend, and the two underlying measures point in different directions: the core reading came in softer than expected, which argues that energy costs are not yet spreading across the whole price structure, while the gauge excluding trade services held at 4.7 percent, roughly twice the Fed's target. The divergence between goods, up 1.1 percent, and services, up 0.1 percent, shows the acceleration is concentrated in energy-linked categories rather than broad-based. The BLS will publish September PPI on Oct. 15 and August PCE data are due Sept. 30; economists expect Friday's CPI to show annual consumer inflation easing to 3.3 percent from 3.4 percent, with a 0.4 percent monthly gain.
