# Diesel prices surge as Iran war strains global supply

Record diesel costs: U.S. retail diesel averages above $5.60 per gallon, with California topping $7.41, as global supply disruptions persist. Conflict-driven surge: Iran war has slowed Middle East oil flows, cut global reserves by 250 million barrels, and sent Brent crude over $109 per barrel. Economic ripple effects: High fuel prices are squeezing transport, farming, and manufacturing, and boosting interest in electric vehicles.
