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 fall for good.

Even without food and energy included, annual inflation still hit 3.4 percent in May, far above the Fed’s preferred annual rate of 2 percent, and 0.3 percent last month alone.

“Inflation’s surge is more than an oil price story. Housing, medical care and electricity are also putting pressure on family budgets and overall inflation,” Long said.

Trump had already been facing intense backlash from voters over inflation before he initiated the war in Iran. The president and Republicans are also struggling to show voters they can be trusted to bring prices back down after pledging to do so during the 2024 presidential campaign.

Trump also threatened to derail what could have been a major selling point for the Republican Party ahead of the midterms, abruptly canceling a Wednesday signing ceremony for a bipartisan housing bill cleared by the House earlier this week.

While Trump initially said he was holding off on the legislation amid a feud with Senate Republicans over a voting rights bill, he said at the White House on Wednesday that only lower interest rates would truly unlock the housing market.

“It’s all about the interest rate. Lower the interest rate,” Trump said.

Fed faces more pressure on rates

The Fed, however, is unlikely to be cutting interest rates soon with another batch of hot inflation data behind them.

Members of the Fed’s rate-setting committee voted unanimously last week to keep interest rates steady as inflation continued to rise and the labor market showed signs of improvement.

The combination of higher inflation and stronger economic activity makes it unlikely the Fed would be willing to stimulate the economy through lower interest rates. If both inflation and demand for workers keep improving, the Fed could even be forced to hike interest rates.

“If core inflation persists around current levels in September, or if labor supply bottlenecks have started to push down the unemployment rate, a hike would become likely,” explained Bill Adams, chief U.S. economist at Fifth Third Bank.

“The big near-term upside risks to inflation are from the AI boom putting upward pressure on electronics and energy prices, and from labor-intensive services provided by industries with high proportions of foreign-born workers.”

Global tumult clouds outlook

A long-term resolution to the war in Iran could help pave the way to lower gasoline prices and ease some pressure on inflation. But the uncertainty surrounding the U.S.-Iran pact, along with persistent Israeli military pressure on Lebanon, have raised the risks of future flash points.

The Islamic Revolutionary Guard Corps said Thursday that tankers mush pass through Iranian-controlled routes in the Strait of Hormuz or risk facing attacks, even as international institutions seek to restore normal naval transit through the gulf.

The U.N. International Maritime Organization launched an operation earlier this week to evacuate more than 11,000 seafarers from the strait and confirmed strait crossings rose to 70 on Thursday, according to data and analytics firm Kpler.

Economy prevailing through price hikes

The U.S. economy has still managed to hold sturdy through higher inflation, with consumer spending rising and weekly claims for unemployment insurance falling.

Consumer spending rose 0.3 percent in May when adjusted for inflation, even as prices rose at a faster rate, largely by dipping into their savings or stock market winnings.

“Consumers have run down savings or tapped into wealth to fund spending, highlighted by the drop in the personal saving rate to 3 percent in recent months, from 4.6 percent in 2025. Rising financial wealth continues to be a tailwind to spending from high-income households,” said Michael Pearce, chief U.S. economist at Oxford Economics.
