Since the Iran war began on February 28, U.S. consumers have spent an estimated $100 billion more on fuel, driven by gasoline and diesel price spikes from Strait of Hormuz disruptions. The average household has paid over $760 extra, with Texas hit hardest at $11 billion, followed by California and Florida.
Gas averages $4.15 per gallon now, up from $2.98, while diesel reached a record $5.90, raising fears of broader inflation from higher freight and transport costs. The Brown University tracker shows the total climbing daily amid debates over oil companies' gains and the administration's push to reopen the strait.
