April Inflation Hits 3.8% As Iran War Drives U.S. Energy Costs
U.S. consumer prices rose 3.8% year-over-year in April 2026, the fastest increase in nearly three years, as surging energy costs tied to the Iran war pushed inflation higher.[1]
Higher energy prices made up about 40% of April's CPI increase; energy was nearly 18% higher and gasoline rose more than 28% from a year earlier. Economists say for many workers inflation is now outpacing wage growth and warned headline inflation could top 4% on the next CPI print if oil prices stay high.[1]
AAA reported average U.S. gasoline at about $4.50 per gallon in May 2026, roughly $1.50 above prewar levels, and diesel averaged $5.64 per gallon, about 18 cents below its June 2022 record. The Energy Information Administration projects average retail gasoline will be $3.88 per gallon for the rest of 2026 and $3.62 in 2027, signaling elevated fuel costs ahead.
Analysts link the jump in pump and wholesale fuel prices to supply fears from the Iran war and related oil-market volatility, a dynamic that has pushed energy to be the main driver of the recent rise in headline inflation.[1]
