Iran War Drives U.S. Gas Prices Higher, Strains Household Budgets

Gas prices have climbed back above $4 a gallon, and the pressure is spreading beyond the pump. The average U.S. price reached $4.09 on Friday, the highest since August 2022, as the Iran war rippled into mortgage rates, travel costs, grocery bills and heating oil. Diesel, a key fuel for freight and farm equipment, rose to $5.53 a gallon from $3.64 a year earlier, raising costs for motorists, food delivery drivers, farmers and the U.S. Postal Service.

The central risk is the Strait of Hormuz, the narrow waterway that carries about one-fifth of global oil and liquefied natural gas flows. Any disruption there can move energy markets fast, and those moves reach U.S. households through higher transportation costs, utility bills and food prices. Economists and market analysts say a swift end to the conflict, especially if shipping through the strait fully reopens, could ease the pressure. But even then, relief would not arrive immediately, because fuel and freight costs feed through the economy with a lag.

That chain reaction is already visible in consumer sentiment. Pew Research Center found that 69% of Americans were worried about higher gas prices because of the Iran war, making fuel costs the top public concern. Pew also found that 45% said the U.S. was not doing enough to prevent civilian casualties, underscoring how the conflict is shaping both household economics and public opinion. AAA put the national average for regular gasoline at $4.16 on April 9 and $4.093 on April 16, showing prices remained elevated even after small day-to-day swings.

The strain is landing unevenly across incomes and occupations. Phil Hampton, a part-time delivery driver near Dallas, said he was questioning how much more he should be driving to earn extra money for his family of six. For workers who rely on mileage, the higher cost of gasoline and diesel narrows already thin margins. Matt Schulz of LendingTree and Kate Wood of NerdWallet have pointed to the broader household-budget squeeze, while Austan Goolsbee of the Federal Reserve Bank of Chicago has highlighted the danger that energy shocks could filter into inflation more broadly.

That concern is not abstract. Bloomberg reported that the war fueled the biggest jump in U.S. inflation in nearly four years and drove consumer sentiment to a record low. The longer the conflict lasts, the more those pressures can spread from oil to shipping, from shipping to groceries, and from groceries to monthly budgets. A short disruption may leave only a temporary mark. A longer one could leave families paying more for nearly everything that moves.
