- A 3.9% monthly spike in energy costs accounted for more than 60% of the overall price increase
- Core CPI registered 2.9% annually, with a modest 0.2% monthly rise falling short of projections

Consumer prices in the United States surged in May, with the headline inflation figure reaching 4.2% on an annual basis — the most significant increase recorded since April 2023.
The Bureau of Labor Statistics published the figures on Wednesday morning at 8:30 a.m. Eastern time. Monthly price gains measured 0.5%, representing a slight deceleration from the 0.6% increase seen in April, matching analyst expectations.
Energy costs emerged as the primary driver behind the acceleration. Energy prices climbed 3.9% compared to April, representing more than 60% of the total monthly price increase. The nation has experienced sustained elevated energy expenses for over three months, largely attributed to the continuing confrontation with Iran.
Food costs increased 0.2% on a monthly basis, representing a deceleration from April’s 0.5% advance. On an annual basis, food expenses have climbed 3.1%.
Supermarket Prices Show Welcome Moderation
The grocery sector provided encouraging news. The food-at-home category increased by a mere 0.1% in May, representing a substantial slowdown from April’s 0.7% monthly jump. On an annual basis, supermarket prices have risen 2.7%.
Restaurant prices demonstrated more persistence. The food-away-from-home category advanced 0.3% month-over-month and has climbed 3.5% over the trailing twelve months.
In other categories, auto insurance premiums decreased 1.7% from April, providing some consumer relief. Hospital services expenses increased 0.7%.
Coffee prices maintained their upward trajectory, while cheese costs declined. The report did not provide detailed breakdowns for these individual items.
Core Price Pressures Ease Below Forecasts
Core CPI, which excludes volatile food and energy components, increased 2.9% year-over-year, aligning with consensus estimates. However, the monthly core measurement registered 0.2%, undershooting the 0.3% economist consensus. This milder core reading alleviated concerns about aggressive additional interest rate increases.
For American workers, the report painted a challenging picture. Real average hourly earnings declined 0.1%, indicating that wage growth failed to match the pace of price increases during May.
The Federal Reserve has been monitoring inflation developments carefully. The divergence between an elevated headline figure and subdued core measurement presents policymakers with conflicting signals as they approach their upcoming policy meeting.
Annual consumer price inflation now stands at its most elevated level in three years. The last time the figure reached this magnitude was in April 2023.
The monthly rate of price increases has been moderating — May’s 0.5% advance follows April’s 0.6% gain — yet the year-over-year comparison continues trending unfavorably.
The upcoming CPI report covering June data is scheduled for release in mid-July.
