Iran war adds $100B to U.S. energy costs; diesel surge threatens freight

Brown University's tracker estimates the Iran war has cost U.S. consumers $100 billion in higher energy prices, with costs rising ~$1M every two minutes. Diesel price surge poses a direct threat to freight and travel costs, amplifying economy-wide inflation. The estimate is a cumulative accounting of war-driven price increases, not a forecast, and its precision is uncertain.
