CPI Inflation Eases to 3.1% in April, Shelter Costs Finally Slow

April CPI: A Genuine Disinflation Signal or One-Month Noise?

The Bureau of Labor Statistics reported that the Consumer Price Index rose 3.1% year-over-year in April 2025, down from 3.5% in March and below the 3.3% consensus estimate. On a monthly basis, the CPI rose just 0.2%.

Shelter: Finally Cooperating

The shelter component — which has been the most persistent driver of above-target inflation — rose 4.8% year-over-year in April, the slowest pace since January 2022. This is significant because shelter makes up roughly one-third of the total CPI basket. Leading indicators like Zillow's rent index have been signaling this deceleration for months; the official CPI is now catching up.

Energy: The Wild Card

Energy prices fell 1.1% month-over-month, with gasoline prices dropping 2.4% and natural gas down 3.2%. Lower oil prices — WTI crude has fallen roughly 12% from its February highs — provide a meaningful tailwind to headline inflation through the summer.

Core Services Still Sticky

Core services ex-shelter (sometimes called "supercore") rose 0.3% month-over-month — unchanged from March. This component, which includes categories like airfares, car insurance, and medical services, remains the Fed's main worry as it reflects domestic labor cost pressures.

Market Reaction

Treasury yields fell across the curve following the release, with the 2-year yield dropping 8 basis points to 4.71%. The S&P 500 rallied 0.9% and gold added 0.6%.

Rate cut expectations shifted modestly: markets are now pricing a 28% chance of a September cut, up from 15% the day before. The Fed will want to see two or three more prints in this direction before acting.
