National oil stockpiles are emergency reserves intended to soften the impact of a serious, sudden supply disruption. The International Energy Agency (IEA) requires its members—not every country—to hold stocks equivalent to at least 90 days of net oil imports. That measure is a calculated import-cover ratio, not a promise that one reserve can supply all domestic oil needs for 90 days.
What is the IEA’s 90-day oil stock requirement?
IEA member countries must hold oil stocks equivalent to at least 90 days of net imports. The obligation does not apply to non-members, and the IEA says net exporters are not required to meet the minimum. The IEA’s oil-stocks page, last updated 12 August 2026, describes the requirement and its calculation: IEA oil stocks.

The 90 days refer to the previous calendar year’s average daily net imports, not total domestic consumption. A country’s cover therefore depends on its net imports and on which stocks qualify under the IEA methodology. It should not be read as a guarantee that the country could meet all consumer demand from its reserves for that period.

The IEA divides qualifying emergency reserves by average daily net imports. Its method adjusts imports of primary products and refined products, converts refined products to crude-oil equivalent, and excludes specified items, including naphtha and international marine bunkers. For most members, the calculation also deducts a 4% naphtha yield. The IEA reduces counted reserves by 10% to account for stocks that may not be available, such as tank bottoms.

Who holds the emergency oil stocks?
IEA members choose how to organize their systems. The stocks may be held by the state, a separate agency, or oil companies. Depending on the applicable rules, industry stocks—including some commercial stocks—can count toward a country’s obligation.
- Government stocks: Oil held by the state for emergencies.
- Agency stocks: Oil managed by a separate body on behalf of government or industry.
- Industry stocks: Oil held by companies, including qualifying commercial inventories.
Some qualifying stocks may be located abroad, for example under bilateral agreements that guarantee access during a crisis. Another arrangement is a “ticket”: a contract reserving a stated quantity, quality, and location of crude or products for a period—usually a calendar quarter—while giving the buyer an option to take delivery in an emergency. A ticket provides contractual access; it does not mean the buyer physically owns oil stored in its own facilities.

The IEA assesses the likely market impact before recommending collective action. Its Secretariat considers the estimated supply loss, commercial inventories, and spare production that could become available quickly, consulting producer governments and industry experts. If a disruption is large enough to significantly affect global markets, the IEA may recommend a coordinated response. Member contributions are proportional to each member’s share of IEA-member oil consumption.
The objective is to reduce the economic harm of a sudden, short-term shortage—not to set prices or manage long-term supply. The response can add oil to the market, reduce demand, or do both. Possible measures include releasing emergency stocks, restraining demand, switching fuels, activating spare crude-production capacity available within 30 days, and temporarily relaxing fuel specifications. See the IEA’s explanation of its oil security system.
Where does the additional oil supply come from?
When members release stocks, the oil comes from qualifying government, agency, or industry reserves. A coordinated response can also involve spare production capacity and measures that reduce demand or allow fuel switching. The mix depends on the disruption and on what can be made available in time; a release announcement is not the same as an immediate arrival of finished fuel at a consumer’s local station.
When has IEA collective action taken place?
On 11 March 2026, all 32 IEA member countries agreed to make 400 million barrels of emergency oil stocks available to the market. The IEA called it the sixth collective action and its largest to date. In the same announcement, the agency said member emergency stockpiles exceeded 1.2 billion barrels, with a further 600 million barrels of industry stocks held under government obligation. These are figures reported in the 11 March announcement, not a live inventory total. Read the IEA announcement.
The IEA said that in 2025 an average of 20 million barrels per day of crude oil and products transited the Strait of Hormuz, around 25% of world seaborne oil trade. Its 11 March 2026 announcement said that after the conflict began on 28 February, crude and product export volumes through the Strait had fallen to less than 10% of pre-conflict levels at the time of the announcement. Those figures describe the conditions cited then; they should not be treated as current flow data.

Members can combine government, agency, and industry stocks; crude and refined products; and, where arrangements qualify, stocks held abroad. The approaches differ in who owns the oil, where it is held, and how quickly it can be delivered. When comparing national systems, check the measure and date of days of net-import cover, stock ownership and form, location, whether access is physical or ticketed, and the practical release and delivery arrangements.
How does the U.S. Strategic Petroleum Reserve work?
The U.S. Strategic Petroleum Reserve (SPR) is a national example, not the source of the IEA’s 90-day rule. The U.S. Department of Energy (DOE) manages four sites along the Gulf Coasts of Texas and Louisiana. They store crude oil in deep underground salt caverns, near marine terminals, pipelines, and Gulf Coast refineries. DOE describes the facilities and operating details on its SPR overview and SPR FAQ.
U.S. inventory and capacity figures are date-specific
DOE’s Quick Facts page reports 294.1 million barrels across the four sites as of 20 August 2026, against authorized storage capacity of 714 million barrels. The same page reports 411 million barrels at year-end 2025, equal to approximately 125 days of U.S. crude-oil net imports under DOE’s calculation. These figures have different dates and should not be conflated with one another or presented as a current live inventory.

DOE lists a maximum nominal drawdown capability of 4.4 million barrels per day and says oil can enter the U.S. market 13 days after a presidential decision. That process includes a competitive sale and contract awards. DOE also says the maximum rate can be sustained for up to 90 days before declining as the caverns empty. The drawdown figure is a maximum capability, not a measure of how quickly gasoline reaches drivers.
The SPR holds crude, classified by DOE as sweet or sour, rather than finished gasoline. Crude must be delivered into the refining and distribution system before it becomes consumer fuel.
How fast can oil be released from the U.S. Reserve?
According to DOE, market deliveries can begin 13 days after a presidential decision. Its stated maximum nominal drawdown is 4.4 million barrels per day; the FAQ says that maximum can last up to 90 days before declining as caverns empty. The competitive sale process, transportation, refining, and distribution all affect when crude becomes usable fuel.
What type of crude oil is stored in the Reserve?
The SPR contains crude oil classified as sweet or sour, not gasoline or other finished consumer fuels. DOE says the Gulf Coast locations provide access to nearby refineries and delivery infrastructure.
How is days of import protection determined?
DOE’s figure is based on U.S. crude-oil net imports, not total domestic oil consumption. For example, DOE reported that 411 million barrels in the SPR at year-end 2025 represented approximately 125 days of U.S. crude-oil net imports under its calculation. That is a dated measure of import cover, not a guarantee that the reserve could supply every U.S. oil need for 125 days.
