The war in Iran has reignited short-term inflation with monthly price increases pushing to levels not seen since Americans were last grappling with a full-blown price crisis four years ago as the economy was emerging from the pandemic.
Consumer prices posted their biggest monthly gain since 2022 in March, rising 0.9 percent from February, according to the Bureau of Labor Statistics. On an annualized basis, prices rose 3.3 percent, up sharply from 2.4 percent the month before and the highest level since May 2024 on a yearly basis.
Energy prices in the consumer price index jumped about 11 percent last month, the largest monthly increase in more than 20 years, fueled by a 21.2 percent increase in the price of gasoline, which was the biggest jump in the history of the index.
The conflict in Iran has fueled a rapid rise in the cost of oil and refined petroleum products, including gasoline and diesel, with ripple effects spreading into fertilizers and other goods whose production or transport depends on fossil fuels. The renewed inflation surge will intensify pressure on the Trump administration, which has made tackling high prices a central political promise.
The White House on Friday said the spike reflects temporary energy disruptions from the conflict and pointed to falling prices for eggs, beef, prescription drugs and dairy as evidence that President Donald Trump’s broader economic agenda is working. The administration said it remains focused on keeping oil supplies moving through the Strait of Hormuz.
“As the Administration ensures the free flow of energy through the Strait of Hormuz, the American economy remains on a solid trajectory thanks to the Administration’s robust supply-side agenda of tax cuts, deregulation, and energy abundance,” said White House spokesman Kush Desai.

There are encouraging signs that the report isn’t a harbinger of renewed inflation. The surge in overall prices masked a more optimistic signal underneath, with “core inflation” — which strips out volatile food and energy prices — holding relatively steady. It rose just 0.2 percent last month, or 2.6 percent on an annual basis.
Even so, some economists cautioned that relief is unlikely to reach consumers quickly, even if the ceasefire announced this week holds. Negotiations in Pakistan are expected to begin Saturday with Vice President JD Vance leading the U.S. delegation.
“Even if the negotiators in Pakistan stick the landing and the ceasefire turns into a durable period of non-conflict, the lagged impact of the oil and energy shock will impact consumers in a variety of ways through the remainder of 2026,” said Joe Brusuelas, chief economist at RSM.
Private-sector data suggests the surge is already well underway. The State Street PriceStats index, which tracks retail prices in near-real time, recorded a 1.5 percent monthly increase in March — the largest single-month jump since the series began in July 2008. On an annual basis, the index put inflation at 4 percent, a level not seen since early 2023.
“This means that in just one month, the inflation picture has shifted materially,” said Michael Metcalfe, head of macro strategy at State Street Markets.
The March report arrives as inflation completes five consecutive years above the Federal Reserve’s 2 percent target — and as hopes of a final push back to normal appear to be fading. After cooling markedly from its 2022 peak, price growth had appeared to stall at around 3 percent, about one percentage point above where the Fed wants it, even before the Iran conflict added fresh fuel.
Without evidence that inflation is easing, the Fed is likely to struggle to make the case for cutting rates from their current range of 3.5 to 3.75 percent — unless the labor market weakens sharply enough to force their hand.
