Inflation surges to 3.8%, fueled by war-driven energy costs

For a restaurant owner, April’s inflation report was a brutal three-way squeeze: pay more for food and energy, then decide whether to raise menu prices, shrink portions or accept thinner margins. That pressure landed as food prices rose 3.2% from a year earlier, with food away from home up 3.6%, while gasoline prices surged 28.4% and the average regular gallon topped $4.50 on May 12, about 44% above a year ago.

U.S. consumer prices climbed 3.8% in April compared with a year earlier, the fastest annual pace since May 2023. The Consumer Price Index rose 0.6% from March, a sharp monthly increase that showed inflation was still accelerating rather than easing. Energy prices accounted for more than 40% of the total CPI increase, underscoring how heavily the war with Iran has reshaped costs for households and businesses across the United States.

The data pointed to a price shock that is broadening beyond the gas pump. Core inflation, which strips out food and energy, rose 2.8% from a year earlier, showing that the pressure is seeping into more of the economy. Airline fares jumped 20.7%, adding another sign that higher fuel costs are rippling through travel, shipping and the services sector.

April’s reading was also hotter than economists expected. Forecasters had looked for 3.7% annual inflation, but the actual increase came in at 3.8%, a reminder that the inflation hit tied to the 10-week war with Iran is proving larger than many anticipated. March’s CPI report had already shown inflation at 3.3% year over year, the first major shock linked to the conflict, and April extended that surge.

The stakes are especially high for small businesses that cannot absorb cost increases for long. A neighborhood restaurant can raise prices only so far before customers cut back, but holding prices steady means giving up margin at the very moment food, fuel and utility bills are climbing. That is the central economic strain in this inflation wave: the costs are immediate, but the ability to pass them on is limited.

The Bureau of Labor Statistics said its next CPI release, covering May 2026, is scheduled for June 10. Until then, the April numbers suggest the inflation fight is far from over, and the pressure is falling hardest on the businesses least able to pass the bill along.
