KEY POINTS
- April PPI rose 1.4% month-over-month and 6.0% year-over-year, the largest annual increase since December 2022.
- Energy contributed more than half of the headline move; core PPI ex-food and energy was up 0.5% MoM, also above expectations.
- Watch the May CPI release on June 10 — if it confirms a re-acceleration, the September FOMC is in play for a hike.
The Producer Price Index for final demand rose 1.4% in April, the largest monthly increase in three and a half years, and 6.0% year-on-year, ending a months-long debate over whether the recent run of inflation prints was a head fake. They were not. The April PPI release confirms what last week's April CPI hinted: the U.S. economy is running through a second inflation impulse, this one driven by energy prices and tariffs working their way through the supply chain.
Where the Pressure Built
Energy was the headline story but not the only one. Final-demand energy prices jumped 4.7% in April, accounting for more than half of the monthly increase, as Brent crude held above $107 and refined products tracked higher. Food prices rose 0.6%. Core PPI — excluding food, energy, and trade services — rose 0.5% on the month and 3.2% on the year, with services inflation accelerating as freight and warehousing costs reset higher.
What makes this print uncomfortable for the Fed is the breadth. The diffusion index — the share of categories showing month-over-month gains — was at 71%, well above the post-2022 average of 58%. That is not a single-line surprise driven by one commodity. That is broad-based pricing power, and it is showing up in the categories that flow most directly into the consumer basket two to three months later.
The Tariff Pass-Through Question
Wall Street economists have spent the past six weeks arguing about whether tariffs are showing up in prices. April's PPI ends that argument. The category that captures imported intermediate goods was up 0.9% on the month, a sharp acceleration from March's 0.3%. That is consistent with importers having drawn down pre-tariff inventory and now sourcing at the new tariff-inclusive prices.
The lag matters. Most tariff escalations from the first quarter only began flowing into wholesale prices in March and April. The second-quarter pass-through will be larger, not smaller. According to CNN's analysis of the data, the wholesale impulse is now feeding directly into retail margins, with companies in food, apparel, and consumer electronics signaling on Q1 earnings calls that price increases will continue through Q3.
What This Means for the Fed
The Federal Reserve last met April 29 and held the funds rate at 3.5%–3.75% for a third consecutive meeting. The June meeting is now effectively closed to a cut. The September meeting, which the rate-cut camp had pinned its hopes on, looks like a coin flip between a hold and a hike. The minutes from the April meeting, released in three weeks, will tell us how many committee members already had hike language in their toolkit.
Boston Fed President Susan Collins this week explicitly warned that inflation pressures will persist through 2026 and that no rate cuts should be expected. That language from a centrist member is the most direct signal yet that the staff projection at June's Summary of Economic Projections will move higher on inflation and the dot plot will lose the cut.
The next macro test arrives June 10 with the May CPI release. Cleveland Fed's nowcast currently projects May CPI at 0.4% month-on-month and 3.6% year-on-year, a slight cooling from April's 3.8% headline. If the print comes in hot — say, 0.5% or above — September becomes a live meeting for a 25-basis-point hike. If it cools to 0.2%, the Fed buys back optionality. Either way, the days of pricing in two cuts by year-end are over, and the equity market has yet to fully absorb what that means for valuation.
