- Trump posted on Truth Social that “big Oil Companies are not dropping their price at the pump commensurate with the sharply lower prices they are paying for Oil,” and ordered the DOJ to investigate — he did not specify the legal theory or what instructions were given.
- Average nationwide gasoline prices have fallen 14% since late May and are now below $4/gallon, but they remain above the five-year seasonal average; the gap between falling crude prices and slower pump-price declines is the core of Trump’s complaint.
- US commercial gasoline inventories are near their lowest levels for this time of year since 2014, constraining how quickly prices can fall even as crude drops — supply, not oil company margins, is a significant factor in the lag.
- High gas prices are a key political vulnerability for Republicans ahead of November midterm elections, with Democrats actively attacking the administration on cost-of-living issues at the pump.
What Happened?
President Trump posted on Truth Social demanding that oil companies lower pump prices faster, saying gasoline prices “better start going down a lot faster than what I’m seeing!” and announcing the Justice Department would investigate. The directive follows the US-Iran sanctions waiver issued Monday that allows Iran to sell oil in dollars for two months — a move that has pushed Brent crude below $78/barrel. But retail gasoline prices, which surged to their highest level since 2022 when US and Israeli strikes closed the Strait of Hormuz, have fallen more slowly than crude. Average nationwide prices have dropped 14% since late May to just below $4/gallon according to AAA data — still above the five-year seasonal average.
Why It Matters?
The lag between crude price declines and pump price reductions is partly structural: crude accounts for roughly half the cost of gasoline, with refining margins, distribution costs, and taxes making up the rest. More critically, US commercial gasoline stockpiles are near their lowest levels for this time of year since 2014 — depleted reserves mean refiners can maintain higher margins even as crude falls. A DOJ investigation into oil company pricing faces significant legal hurdles; absent evidence of collusion or price-fixing, market-driven pricing differentials are not typically actionable. The political backdrop is the real driver: high gas prices are one of the most visible and politically damaging economic indicators for the party in power, and Trump needs prices lower before November midterms.
What’s Next?
Treasury Secretary Bessent said Tuesday he expects inflation — including gas prices — to fall as the Iran conflict winds down, calling the situation “on the other side of this conflict.” The Fed’s preferred inflation gauge is expected to show a 4.1% year-over-year jump in May (3.4% core), due Thursday — well above the 2% target. If Hormuz traffic continues normalizing and Iranian oil flows increase under the waiver, crude should continue drifting lower, eventually pulling pump prices down further. Whether the DOJ investigation produces any actionable findings is secondary to the political signal: Trump is publicly pressuring the energy industry to pass through falling crude costs faster.
