US PCE inflation jumps to 4.1% in May, highest since April 2023
The Fed's preferred price gauge accelerated for the third month running, with AI-driven memory and chip costs now visible in consumer price data
Summary
The Bureau of Economic Analysis reported May 2026 personal consumption expenditures inflation at 4.1% year-on-year, up from 3.8% in April and the highest since April 2023. Monthly PCE rose 0.5%; core PCE (excluding food and energy) came in at 3.3% year-on-year. The acceleration reflects AI-driven memory and semiconductor costs passing through supply chains into consumer electronics, with Apple's June price hike visible in the data. Bitcoin fell from $61,800 to $58,000 within an hour of the release.
Why it matters
The Fed's 2% target is now more than two percentage points away, and a third consecutive monthly acceleration reduces the likelihood of any rate cut before the November FOMC meeting. Sustained dollar strength from deferred easing is already straining emerging-market currency reserves, and the memory-price transmission channel means the next CPI print is unlikely to reverse course.
What to watch
- Fed Chair commentary on whether this reading changes the balance-of-risks guidance.
- June CPI data (due mid-July) for confirmation or reversal of the trend.
- Whether FOMC minutes explicitly name the AI memory price channel as an inflation driver.
