Yes. Releasing oil from a government reserve can ease gasoline prices by adding crude supply, but the effect depends on market conditions and is not guaranteed. For the U.S. release coordinated with international partners in 2022, the Treasury estimated a reduction of 17 to 42 cents per gallon; that is a model-based estimate for that episode, not a standard result for future releases.
How a reserve release can affect gas prices
A release adds crude oil to commercial supply. The oil then travels by pipeline or vessel to refineries, where it is processed into gasoline and other petroleum products before reaching distribution centers. It does not go straight from the reserve into drivers’ tanks. The Government Accountability Office describes this route in its 2018 testimony on the Strategic Petroleum Reserve.
More available crude can reduce supply pressure and influence oil-market expectations, which may ease the cost of gasoline. But retail gas prices reflect more than U.S. crude supply. Gasoline is globally traded, and U.S. gasoline prices are closely connected to international markets. An Energy Information Administration analysis of four U.S. regions found Brent crude prices more important than West Texas Intermediate (WTI) prices as a determinant of U.S. gasoline prices. The EIA analysis of crude oil spot prices explains that connection.
How much did the 2022 release lower prices?
In a July 26, 2022 analysis, the U.S. Treasury estimated that the U.S. Strategic Petroleum Reserve release, coordinated with releases by International Energy Agency partners, lowered U.S. gasoline prices by 17 to 42 cents per gallon. Using an alternate method, it estimated a 38-cent-per-gallon reduction for the coordinated release.

For the U.S.-only release, Treasury’s demand-elasticity method estimated a 13-to-31-cent-per-gallon impact; its alternate method estimated 33 cents. These figures describe the same 2022 episode through different methods, not separate observed price drops. Treasury’s analysis is available at How the Release of Oil from the Strategic Petroleum Reserve Lowered Gasoline Prices.
Why the estimate is not a promise
Treasury’s estimates rely on assumptions, including full pass-through from crude prices to gasoline prices. Its analysis considered short-run demand elasticities of 0.08 and 0.20, and cautioned that tight refining markets could prevent crude-price changes from passing through one-for-one to retail gasoline. The actual effect of another release could differ with the amount and pace of oil released, other countries’ participation, the disruption being addressed, refinery conditions, product inventories, and supply and demand.

That is why a release may not produce an obvious or immediate decline at the pump. Even if crude supply eases, refinery constraints or changes elsewhere in global markets can offset the effect. Comparing releases by headline cents-per-gallon figures alone can also mislead: estimates may cover U.S.-only or coordinated releases, use different methods, or refer to different time windows.
