May CPI came in at 4.2% year-over-year — the highest since April 2023, the third consecutive monthly acceleration. May PPI came in at 6.5% annually and 1.1% for the month — beating estimates and the highest since November 2022. Stage 1 intermediate demand PPI hit 12.3% annually — the largest increase since June 2022. But core CPI’s monthly reading came in below estimates at 0.2%. That one data point is the most important signal in this week’s back-to-back prints — and it is the reason the inflation story in May is more nuanced than the headlines suggest.
Two back-to-back inflation prints in two days. May CPI released Wednesday. May PPI released this morning. Together they form the most complete picture of the US inflation pipeline available to consumer lenders before Kevin Warsh chairs his first FOMC meeting on June 17. Here is the precise read — including the one data point that makes May’s inflation story meaningfully different from April’s.
The Bureau of Labor Statistics released May CPI on Wednesday. Headline CPI rose 0.5% for the month — slightly below April’s 0.6% but in line with the Dow Jones consensus — pushing the annual rate to 4.2%. That is the highest reading since April 2023, and the third consecutive month of acceleration from the 2.4% reading in January 2026. The trajectory since the Iran war began February 28 is the starkest inflation acceleration in a three-month window since the 2021–2022 post-pandemic shock.
The energy component drove the headline. The energy index rose 3.9% for the month, accounting for over 60% of the total monthly CPI increase. On an annual basis, energy is up 23.5% — accelerating from 17.9% in April. Gasoline prices rose 40.5% year-over-year, up from 28.4% in April. Fuel oil is up 58.9% annually. Food inflation accelerated to 3.1% annually, up from 2.3% in April — the first month in which food inflation materially stepped up beyond the prior trend, confirming that energy cost passthrough into the food supply chain is now active. Shelter rose 3.4% annually, a slight acceleration from 3.3%.
The most important single number in Wednesday’s CPI report is the one that received the least attention in the headline coverage. Core CPI — excluding food and energy — rose just 0.2% for the month, below the 0.3% estimate and a meaningful deceleration from April’s 0.4% monthly reading. On an annual basis, core CPI was 2.9% — in line with estimates and only a tick above April’s 2.8%.
This matters structurally. The April PPI report — released last month — showed services inflation running at 1.2% for the month, the largest monthly services gain since March 2022, and warned that pipeline inflation was becoming structural rather than transitory. May’s core CPI 0.2% monthly reading does not confirm that passthrough. Core commodities prices actually declined 0.1% for the month. The energy spike is running hot at the consumer level. The broader economy is not yet showing the kind of demand-driven, services-led inflation that characterized 2021–2022.
Navy Federal Credit Union chief economist Heather Long provided the most precise framing: “Americans are getting squeezed financially by inflation that’s back at a 3-year high. The frustration for many Americans is that so many of the basics are up in price right now — gas, food, electricity, and medical care are all clear pain points that are above 3% inflation. Ending the war in Iran will help to moderate inflation, but the worst is likely still to come for rising food prices.” The “worst is likely still to come for food prices” observation is the forward-looking signal that matters most for consumer lending — food inflation at 3.1% in May is the leading edge of what May’s PPI data says will arrive in grocery prices over the next 60 to 90 days.
The Bureau of Labor Statistics released May PPI this morning. Final demand PPI rose 1.1% for the month — beating the 0.7% Dow Jones consensus and matching April’s revised pace (April was revised downward from the initially reported 1.4% to 1.1%). On an annual basis, PPI hit 6.5% — the highest since November 2022, accelerating from April’s revised 5.7%.
The most significant single data point in the May PPI report is the goods component. Final demand goods prices posted their biggest single-month gain since BLS began tracking this data series in 2009. Nearly 80% of the goods increase came from a 10.7% jump in energy. Wholesale gasoline prices surged 23.4%. Diesel fuel, industrial chemicals, aluminum base scrap, and jet fuel all rose significantly. The stage 1 intermediate demand index — the earliest stage of the production pipeline — rose 3.2% for the month, the largest increase since the data series began in December 2009, and is up 12.3% annually — the largest 12-month increase since June 2022.
The core PPI excluding food, energy, and trade services rose 0.8% for the month — the biggest monthly gain since March 2022 — and is up 5.1% annually, the most since October 2022. This is the number that reconciles May’s surprisingly soft core CPI print with the broader pipeline data. The producer-level cost pressures that show up in core PPI — wages, processing costs, trade services margins — are running hot. They have not yet fully transmitted to core consumer prices. The 60-to-90-day transmission lag means June and July core CPI will reflect May’s core PPI acceleration.
The BLS publishes PPI data across multiple stages of the production pipeline — from stage 1 (earliest inputs) through stage 4 (closest to final consumer prices) and then final demand. Reading the stages together is more informative than reading the headline alone.
Stage 1 intermediate demand — the raw materials and early inputs that feed into everything downstream — rose 3.2% for the month and 12.3% annually. That is an extraordinary reading. It means the upstream inflation pressure is not easing. Stage 3 intermediate demand — further along the production chain — rose 1.9% for the month, the largest increase since May 2022. Stage 4 intermediate demand is up 6.5% annually. Final demand — what producers receive for goods and services sold to end users — is up 6.5% annually.
The transmission sequence from stage 1 to consumer prices typically runs 60 to 120 days depending on the supply chain segment. May’s 12.3% annual stage 1 reading — the largest in the data series’ history — is telling you what June and July consumer prices are likely to show before BLS publishes them. The May core CPI softness (0.2% monthly) is not a signal that inflation is returning to target. It is a one-month respite in the middle of an accelerating pipeline.
Kevin Warsh chairs his first FOMC meeting in six days. He walks in with: headline CPI at 4.2% (highest since April 2023), PPI at 6.5% (highest since November 2022), stage 1 intermediate demand PPI at 12.3% annually (series record), core PPI ex food/energy/trade at 5.1% (highest since October 2022), and a core CPI monthly print of 0.2% that is the one dovish data point in the entire dataset.
The market reaction to the two prints was a reduction in rate hike probability — from approximately 39% before the prints to the high-20s after the core CPI softness. The logic: if core consumer prices are only rising 0.2% per month, the broad inflation is still concentrated in energy, and an energy-concentrated shock does not require the same monetary policy response as demand-driven inflation. Warsh’s committee will debate exactly this distinction on June 17.
The counterargument — which the three FOMC hawks will make — is that the pipeline data tells a different story than the monthly core print. Stage 1 PPI at 12.3% annually does not produce a sustained 0.2% monthly core CPI reading. The passthrough is delayed, not cancelled. The June and July core prints will be the test. If June core CPI monthly comes in at 0.3% or above, the rate hike probability jumps back toward 40%. If it comes in at 0.2% again, the hold-through-2026 case strengthens.
The food inflation acceleration to 3.1% annually is the most underreported number in Wednesday’s CPI. Food at home rising at its fastest monthly pace since August 2022 is not a gasoline story. It is the energy passthrough into the food supply chain — transportation costs, processing costs, packaging costs — that Heather Long flagged explicitly as having worse to come. For lower-income borrowers whose food spending represents 15–20% of household budgets (versus 8% for the average CPI basket), a 3.1% annual food inflation rate on top of 40.5% annual gasoline inflation is the household budget pressure that is currently converting to missed payment risk in your Q2 data. It is not future risk. It is current.
The core CPI monthly softness is real but temporary. The 0.2% monthly core reading is genuinely better than expected — core commodities declining 0.1% is a clean data point that suggests demand-driven inflation has not yet materialized. But the 5.1% annual core PPI ex food/energy/trade, the 0.8% monthly reading in that same measure, and the 12.3% annual stage 1 pipeline data are all running in the opposite direction. Use the core CPI softness to inform June’s FOMC positioning. Do not use it to revise your consumer credit stress assumptions. The pipeline will deliver.
Stage 1 intermediate demand at 12.3% annually is the most consequential single number in this week’s data for 90-day forward planning. Every lender who is building Q3 reserve assumptions, pricing Q3 originations, or stress-testing Q3 delinquency scenarios should anchor those assumptions to the upstream pipeline data, not to the lagging consumer price level. The 4.2% headline CPI is where consumer prices were in May. The 12.3% stage 1 PPI is where consumer prices are going. Price the difference into your Q3 assumptions now.
Warsh’s first meeting outcome is less important than the June jobs report on July 3. The FOMC will almost certainly hold on June 17 — the core CPI softness gives Warsh the data cover to hold without appearing to ignore inflation. The June jobs report releasing July 3 is the more consequential data point: it will be the first employment read after student loan garnishments began ramping July 1, after three months of real wage compression, and after the Phase 3 credit stress described in the June Executive Brief has had a full month to register in payroll behavior. A sub-75,000 June jobs number would force a fundamental reassessment of the entire H2 2026 monetary policy and consumer credit outlook. Watch it closely.
