SPR Depletion and Release Plan
SPR fell to 340.3 million barrels week ending June 12, its lowest since 1983. An 8.9 million-barrel weekly drawdown—third steepest on record—has cut the stock by roughly 75 million barrels since Iran war began in late February. Trump administration plans to loan 172 million barrels over 120 days to temper gasoline prices $4.07 per gallon.
Historical Context
The SPR, created in 1975 after the 1973 oil crisis, can hold about 700–714 million barrels. It has been drawn down during Desert Storm, Hurricane Katrina, the 2011 Libyan war, and the 2022 Russia-Ukraine conflict. Under Biden, 290 million barrels were withdrawn, including a 180 million-barrel release in 2022, the largest single drawdown.
Inventory and Release Mechanics
DOE data show the SPR at 340.3 million barrels—about one-third of capacity. The exchange program loans oil with a 26 percent return rate, and the administration aims to add 200 million barrels within a year, a 20 percent net increase. The U.S. consumes about 21 million barrels daily, and analysts say a functional reserve should hold at least 150–200 million barrels.
Government Position
An Energy Department spokesperson said the March plan follows International Energy Agency effort to stabilize markets, protect the United States from supply shocks, and that the loan-based release “helps stabilize oil markets at no cost to U.S. taxpayers,” with a pledge to refill the SPR after the conflict.
Industry and Analyst Concerns
Mike Sommers, CEO of the American Petroleum Reserve, warned, “We’re raising alarm bells… we’re getting to levels where we are starting to be concerned.” Andy Lipow of Lipow Oil Associates said the releases averted a $150-per-barrel scenario but cautioned the pace may need to slow.
Impact on Energy Security
The half-capacity SPR reduces U.S. flexibility to absorb future supply shocks, if the Strait of Hormuz stays partially closed or a Gulf hurricane curtails production, and adds political pressure on President Trump as gasoline prices remain above $4 per gallon ahead of the mid-terms.
Conflicting Minimum-Level Views
De Haan cites a functional floor of 150–200 million barrels, Sommers says at least 20 percent full is needed, the DOE inspector general recommends roughly 150 million barrels to avoid cavern collapse, and law sets a minimum of 252.4 million barrels.

- “We're approaching unheard of inventory levels,” — Neil Chapman, Exxon
Upcoming Developments
U.S. and Iranian officials aim to sign an agreement in Switzerland within days to reopen the Strait of Hormuz, and the administration plans to add at least 40 million barrels after the conflict while continuing the exchange-based refill program through the next year.
