US inflation broke through a level not seen in three years.
The Consumer Price Index rose 4.2% over the past year in May, according to new data from the Bureau of Labor Statistics. Prices climbed 0.5% from April to May alone.
Energy was the main driver. Higher gasoline and energy costs accounted for 60% of May's monthly price increase, as the US-Israel war with Iran continues to disrupt global oil flows.
Food and grocery prices, by contrast, cooled off. Overall food rose just 0.2% and groceries rose 0.1%, down sharply from April's 0.5% and 0.7% increases.
The numbers matched what Wall Street expected. Economists had forecast a 0.5% monthly gain and a 4.2% annual rate, according to FactSet estimates.
"[4.2%] is still too hot for comfort, but the more important news was that the increase was concentrated mainly in energy, especially gasoline, rather than spreading widely across the economy," said Sung Won Sohn, a professor of finance and economics at Loyola Marymount University.
Core Inflation Tells a Calmer Story
Strip out food and energy, and the picture looks less alarming.
"Core" CPI, the measure economists watch most closely, rose just 0.2% in May. That brought the annual core rate down to 2.9%, below what forecasters had expected.
That gap between headline and core inflation matters. It suggests the price spike is concentrated in oil and gas rather than spreading across the broader economy.
Still, for households filling up at the pump or paying their electric bill, the distinction offers little comfort. Rising energy costs hit budgets directly and immediately.

A Political Problem Before the Midterms
May's inflation data lands at an awkward time for the White House. Affordability has become a top concern for voters heading into the midterms.
President Donald Trump downplayed the report when asked about it. "The numbers were great," he told reporters. "I love it. I love the inflation."
Trump tied his outlook to the war in the Middle East, predicting prices would ease once oil moves freely through the Strait of Hormuz again.
"It's coming down," he said. "It's going to come down like a rock."
The report is also the first major inflation reading since Kevin Warsh was sworn in as Federal Reserve chair, succeeding Jerome Powell. With inflation rising and the labor market still holding up, many economists now expect the Fed to leave interest rates unchanged, or possibly consider raising them.
Echoes of 2022, But Not a Repeat
The last three months have produced the fastest run of price increases since the spring of 2022, when inflation was racing toward a 41-year high of 9.1%.
That comparison is unsettling. But economists say this round is unlikely to reach those extremes. Current projections put inflation peaking somewhere between 4.5% and 5% this year.
"Inflation might not get worse, but it's going to be a bit warm for the time being," said Nancy Van Houten, lead US economist at Oxford Economics. "It might not cool until next year."
'There's Still a Lot in the Pipeline'
Some economists warn the worst price effects from the war haven't even shown up yet.
Diane Swonk, chief economist at KPMG, says underlying inflation remains stubborn and is now spreading across more categories rather than narrowing.
"What we've got is hot, sticky and persistent underlying inflation, with the dispersion of price increases broadening again, instead of narrowing," she said.
The closure of the Strait of Hormuz has choked off more than just oil. It has also disrupted shipments of metals and fertilizer, key inputs for farming and manufacturing.
Swonk said food prices haven't fully reflected the war's impact yet. Higher fertilizer and diesel costs, combined with reduced crop yields, likely won't show up in data until the fall harvest and into 2027.
Layered on top of that are new tariffs expected this summer, rising shipping and packaging costs tied to oil, and supply disruptions in emerging markets that have already idled some manufacturing.
Even the AI boom is adding pressure, pushing up electricity prices and the cost of certain electronic components, according to Swonk.
Paychecks Are Losing Ground
Rising prices are now outpacing wage growth, and the gap is widening.
Real, inflation-adjusted wages fell for the second straight month, with the decline deepening to 0.7% in May from 0.3% in April.
That erosion in purchasing power could weaken consumer spending, one of the main engines driving the US economy.
"It's not '22, but it doesn't need to be, because '22 started from a lower level," Swonk said. "It's much like stock returns compound to build wealth, inflation compounds to keep the level of prices out of reach for too many, and now they're accelerating again."
For many households, the math is simple: paychecks are stretching less far each month. Building a financial buffer has become more urgent, not less.

What Comes Next
The official CPI data and methodology are published by the Bureau of Labor Statistics, the government agency responsible for tracking consumer prices nationwide.
For now, the path of inflation appears tied closely to the war in the Middle East and how quickly oil markets stabilize. Until the Strait of Hormuz reopens fully, economists say energy-driven price pressure is likely to persist.
Whether that pressure eases by year-end, as the administration hopes, or lingers into 2027, as some economists warn, will shape both household budgets and the Federal Reserve's next move.
