Economic Burden on American Households
Researchers at Brown University’s Climate Solutions Lab estimate that the war in Iran has added roughly $100 billion in fuel expenses for U.S. consumers since the conflict began. The calculation separates $55 billion attributable to higher gasoline prices and $45 billion to higher diesel prices, based on comparing actual 2024 prices with a counterfactual scenario without the war-driven oil surge. The total translates to an average cost of about $750 per household, with larger impacts for families that own multiple vehicles or have long commutes.
Fuel Price Surge Since the Conflict
U.S. gasoline prices, which averaged under $3 per gallon before the war, have risen to approximately $4.15 per gallon. Diesel, used in trucks, farm equipment and power generation, has followed a similar upward trend, raising costs for groceries, utilities and other goods. Analysts link the price spikes to the combined effect of U.S. and Israeli military actions and Iran’s closure of the Strait of Hormuz, a chokepoint that moves about a quarter of global oil supplies.
Human Toll and Public Sentiment
The conflict has resulted in 18 U.S. service-member deaths and around 800 wounded. A Reuters/Ipsos survey shows public support for the war at 31 %, while President Donald Trump’s overall approval rating sits at 33 %.
