US strategic petroleum reserve falls to 282.6 million barrels, lowest since 1982

The United States' Strategic Petroleum Reserve (SPR), the government's emergency stock of crude oil, held about 282.6 million barrels in the week ending October 23, 2026, according to weekly government data reported on October 26 and 27. That is its lowest level since October 1982. The reserve has been drawn down steadily since March, when the US government ordered a large emergency release as its share of a coordinated international effort to calm oil markets during the disruption of shipping through the Strait of Hormuz.

The SPR is a government stock of crude oil, held in underground salt caverns, meant to keep refineries supplied if imports or production are cut off. Releasing oil from it adds supply to the market and can help hold down prices in a crisis, which is why governments use it, and why rich countries coordinate releases through the IEA.

This year's crisis has been unusually severe. The disruption of tanker traffic through the Strait of Hormuz, the narrow sea passage between Iran and Oman through which a large share of the world's oil exports pass, pushed prices sharply higher and led to the coordinated release. The SPR helped cushion the shock, but the cost is a much thinner safety margin. With the reserve at about 40% of capacity, the United States has less oil to release if another emergency strikes, and refilling it will mean buying back crude, which could itself push prices up when it happens.

For Indian readers, the US reserve matters because oil is priced in a single global market. When the world's largest emergency stock runs low, traders worry about how much spare oil is available in a crisis, and that can make prices jumpier. India imports most of the crude it uses, so higher or more volatile global prices feed into the country's import bill, the rupee and, eventually, fuel and transport costs. The US experience is also a reminder of how fast emergency stocks can be used up in a long crisis.

Short-term: Weekly withdrawals have slowed, and the reserve is now falling by small amounts. Markets will watch whether the government sells more oil, as further proposals for deliveries in November and December have been reported, or begins to refill the reserve.

Long-term: Washington faces a choice between keeping the reserve low and saving money, or rebuilding it, which would add to demand for crude. A low reserve also weakens the West's ability to respond jointly to future supply shocks.

Who is affected: US energy policymakers, oil traders and refiners, oil-importing countries such as India, and consumers worldwide whose fuel prices depend on the global crude market.
