April PCE Report Delivered Mixed Read For Fed

Headline Personal Consumption Expenditure (PCE) inflation accelerated to 3.8% year-over-year, the hottest since early 2023 – with the monthly print up 0.4%, but core PCE rose just 0.2% on the month and 3.3% year-over-year, broadly in line with estimates.

Real personal spending grew just 0.1%, personal income was essentially flat, and first-quarter GDP was revised lower by 0.4 percentage points to 1.6% on softer investment, painting a picture of a consumer that is no longer outrunning prices.

The mixed macro print did little to soften the Fed’s hawkish chorus. St. Louis Fed President Alberto Musalem said rate hikes remain on the table if price pressures fail to converge back to the 2% target, echoing similar warnings from Fed Vice Chair Philip Jefferson and Minneapolis Fed President Neel Kashkari.
