America’s emergency oil cushion just shrank to a size not seen since Ronald Reagan was in his first term.
Story Snapshot
- The Strategic Petroleum Reserve dropped below 300 million barrels, the lowest level since 1983, after falling 6.1 million barrels in a single week.
- President Trump ordered the release of up to 172 million barrels in March to ease supply shocks from the Iran war and the disruption in the Strait of Hormuz.
- The reserve has now shed over 350 million barrels across four years, covering both the Iran conflict and Russia’s war in Ukraine.
- Government watchdogs are asking whether the country still has a real long-term plan for refilling the stockpile.
Reserve Falls Below 300 Million Barrels for the First Time Since 1983
The Strategic Petroleum Reserve fell to 298.7 million barrels last week, dropping below the 300 million mark for the first time in more than four decades.
The Department of Energy reported a one-week decline of 6.1 million barrels, continuing a steady slide that began earlier this year. The reserve, built after the 1970s oil embargoes, was designed to hold hundreds of millions of barrels for emergencies just like this one.

Trading data confirms the trend held through the following weeks, with stocks slipping further to 304.8 million barrels before dipping again, each report repeating the same grim marker: lowest since 1983.
The reserve’s capacity tops out near 714 million barrels, meaning the current stockpile sits at less than half of what the system was built to hold.
Iran War and the Strait of Hormuz Pushed the Drawdown
The slide traces back to March, when President Trump authorized releasing up to 172 million barrels to counter the impact of the Iran war on global energy supplies.
Iranian attacks had slowed tanker traffic through the Strait of Hormuz, a narrow waterway that carries a huge share of the world’s oil shipments. The move mirrored a coordinated release among International Energy Agency member nations totaling 400 million barrels worldwide.
By mid-July, weekly reports showed the reserve had already fallen to 316.5 million barrels, the lowest point since April 1983, as the Department of Energy kept releasing crude to calm markets rattled by the conflict. Government data going back decades shows just how steep this drop has been.
Reserve levels sat near 395 million barrels at the start of 2025, meaning the country has lost a quarter of its emergency oil supply in under two years.
Watchdogs Question Whether a Long-Term Refill Plan Exists
The Government Accountability Office has tracked more than 500 million barrels released from the reserve over its history, with most of that drawdown happening recently between the Ukraine war response and the current Iran-driven releases.
The watchdog agency has flagged aging storage caverns and maintenance backlogs as separate concerns layered on top of the shrinking supply itself. Those infrastructure issues raise a fair question.

Refilling the reserve is not simple or cheap. Buying crude back at scale takes years and depends on market prices staying low enough to make the purchases worthwhile.
Critics on the right have long argued that using the reserve as a price-management tool, rather than a strict emergency backstop, leaves the country exposed the next time a real crisis hits. That argument carries real weight now that the buffer sits at a 43-year low with global tensions still simmering.
Supporters of the drawdown point out the alternative was letting gas prices spike further while Americans dealt with an active war disrupting oil shipping lanes. Both things can be true at once.
The releases did their job cushioning prices during a genuine emergency, and the reserve is now thinner than it has been since before most working Americans were born. Rebuilding it responsibly, without dragging out the process for years, should be a bipartisan priority going forward.
