September PPI Jumps 1.3%, Fueling Fed Rate-Hike Fears

The Producer Price Index for final demand rose 1.3% in September, the sharpest monthly increase since March 2022, more than double the 0.6% gain economists had forecast. The surprise strength, reported Thursday by the Bureau of Labor Statistics and covered by CNBC, has economists warning that the Federal Reserve's fight against inflation is not over heading into its meeting in two weeks.

What the September PPI report showed

September's producer price index came in much hotter than economists forecast on Thursday, underscoring continued inflationary pressure from energy amid the U.S. war with Iran, according to CNBC. The producer price index rose 6.3% year over year, the largest annual increase since 2022, with energy costs driving the index higher and showing signs of spilling into other categories. On a monthly basis, CNBC reported the increase was paced by a 20% rise in gasoline prices, but the strength was not limited to energy: stripping out food, energy and trade services, prices still rose 0.5% for the month, which CNBC said indicated inflation was broader than energy alone.

The report followed a hot inflation reading earlier in the week. CNBC noted the PPI data came on the heels of Wednesday's consumer price index release, which was also hotter than economists anticipated on an annual basis. Axios reported that the policy-sensitive two-year Treasury yield briefly touched 4.95% after Wednesday's CPI number before easing to 4.72% by Thursday morning.

Why the Fed is watching this number

The PPI is not the Fed's preferred inflation gauge, but it feeds directly into the calculation of that gauge. The central bank targets the personal consumption expenditures, or PCE, price index, and Wall Street economists use both the CPI and PPI reports to estimate what PCE will show before the official release. Seven Wall Street estimates gathered by CNBC put core PCE inflation for September, due to be published later this month, at 0.32%, up from 0.25% in August, an upward revision economists attributed to Thursday's hotter PPI print.

That has sharpened the debate over the Fed's next move. "We see real risks the Fed will deliver another rate hike in two weeks' time even as recent Fedspeak tempered expectations for back-to-back increases," wrote Kathy Bostjancic, chief economist at Nationwide, in comments carried by CNBC. Alex Pelle, senior U.S. economist at Mizuho Securities, was more direct: "The picture is not benign with inflation elevated and intensifying," he wrote, adding, "On the economic data alone, there is little reason for the Fed to hesitate to continue moving the policy rate higher."

Separately, Nationwide financial market economist Oren Klachkin wrote that "today's September PPI report reinforces Wednesday's CPI message that inflation is turning higher and moving in the wrong direction for the Fed," according to Axios. Klachkin also pointed to a driver beyond energy, telling Axios that costs tied to the artificial-intelligence data-center buildout are adding upward pressure as businesses pass those costs on to customers.

Key figures

What this does and doesn't tell readers

A hot PPI reading measures prices businesses receive for the goods and services they sell, not what households pay at the register. Because producers often pass rising input costs on to consumers with a delay, economists treat PPI as a leading signal for future consumer-price readings rather than a direct measure of household budgets. That relationship is why Thursday's number factored into Wall Street's forecast for the Fed's own preferred gauge, core PCE, even though PPI itself is a separate report.

The 0.5% figure CNBC cited for prices excluding food, energy and trade services is a narrower slice of the index than the 1.3% headline. It strips out the margins retailers and wholesalers charge, which can move independently of underlying cost pressure. That this narrower measure also rose briskly is the basis for Mizuho's Pelle describing the inflation pressure as broad rather than confined to energy.

What the reporting reviewed here does not establish is the exact calendar date of the Fed meeting Bostjancic referenced as being in two weeks, and the Fed itself has not issued a statement responding to the September PPI data. Any market pricing of rate-hike odds tied to this report would reflect a dated, model-based estimate rather than a commitment from the central bank.

What happens next

Two dated items follow this report. The Bureau of Economic Analysis is due to publish September core PCE inflation later this month, the release Wall Street economists used Thursday's PPI and this week's CPI data to forecast at 0.32%. The Fed's policy meeting that Bostjancic and other economists flagged as being in two weeks from the October 15 report is the next point at which the central bank will act on this data, though it will not yet have the PCE reading in hand.
