U.S. Diesel and Gas Prices Hit Record Highs Following Strikes on Iranian Tankers
National average diesel prices reached a record $5.85 per gallon alongside Labor Day weekend gas prices hitting record highs between $4.14 and $4.15 per gallon. The price surge stems from rising crude oil costs, refinery issues, and escalating geopolitical instability in Ukraine and Iran. In California, these spikes impact trucking fleets, supply chains, and agriculture. The U.S. military retaliated after Iran targeted two warships with ballistic missiles, disabling three Iranian oil tankers.
Why it matters

The military escalation involving Iranian forces and U.S. warships directly threatens petroleum supply routes, driving up global crude prices. Refineries face ongoing operational challenges that compound the market stress, leaving consumers facing unprecedented fill-up expenses.
