Inflation hits 4.1 percent in May: 5 takeaways

Federal inflation data released Thursday showed prices rising at the fastest annual rate in three years, posing serious challenges for President Trump and policymakers.

The Federal Reserve’s preferred gauge of inflation showed prices rising 4.1 percent over the past year and 0.7 percent in May alone. While much of the increase came from higher energy prices tied to the Iran war, the breadth of May price hikes alarmed economists.

Here are five takeaways from the new inflation data.

Costs of Iran war piling up

The new personal consumption expenditures (PCE) report showed the stark costs of the war in Iran, where the closure of the Strait of Hormuz throttled the global supply of oil and other key commodities.

U.S. households spent $552.8 billion on gasoline and other energy products in May, up from $422.3 billion in February and $401.6 billion in May 2025. Prices for gasoline and energy products were up 6.5 percent in May after rising 5.5 percent in April and a whopping 20.9 percent in March, the first full month of the Iran war.

“Inflation is at a 3-year high due to the war in Iran and it’s painful for middle-class and moderate-income Americans,” said Heather Long, chief economist at Navy Federal Credit Union, in an analysis.

Trump’s affordability problem grows

Trump has expressed confidence that inflation would fall rapidly in the wake of the deal struck with Iran last week, which has led to far greater oil trade through the Strait of Hormuz. Prices for crude oil have fallen rapidly in response, and gasoline prices have also begun to tick down in June.

But Long warned that the May inflation data showed far deeper affordability issues for Americans as they wait to see gasoline prices........
