Iran war costs U.S. households $860 each as energy prices surge – economist | 10 Sep 2026 | American consumers are facing higher costs as the war in Iran pushes energy prices higher, with U.S. households having spent over $100 billion more this year due to elevated gasoline and diesel prices, an economist says. Mark Zandi, chief economist at Moody’s Analytics, told FOX Business that “higher oil prices and energy more broadly” have been the main economic consequence of the Iran war felt by U.S. households. “The war has added about $115 billion in additional costs through higher gasoline prices, what we pay at the pump; diesel that goes to everything that’s put on a truck from groceries to Amazon packages; and jet fuel,” Zandi said. “If you add that all up, it’s about $115 billion. And if you divide by the number of households, that’s about $860 per household. So, a typical household is spending $860 more on energy than they otherwise would have if there had been no war.”
