US strategic oil reserves have fallen to their lowest level in 43 years, a milestone that underscores the strain on global energy supplies as geopolitical tensions persist. The drawdown comes as prediction market data suggests a small but real chance that crude oil will hit a new all-time high before the end of 2023.
Why reserves are running low
The Strategic Petroleum Reserve, an emergency stockpile of crude stored in underground salt caverns along the Gulf Coast, has been steadily drained over the past year. The Biden administration authorized the release of more than 200 million barrels in 2022 to combat high gasoline prices after Russia's invasion of Ukraine. Those releases, combined with a slower pace of replenishment, have brought the reserve to its smallest size since 1980.
Odds of a record crude price
Despite the low reserve levels, the probability of crude oil reaching a new all-time high by September 30 is currently estimated at 6.7%, according to prediction market data. That probability rises to 14% for the full year ending December 31. The figures come from betting markets where traders wager on specific price milestones. While the odds remain low, they reflect lingering uncertainty about supply disruptions and demand growth.
What a depleted reserve means
A smaller strategic stockpile leaves the United States with less flexibility to respond to sudden supply shocks. In the event of a new crisis — whether a major hurricane, a pipeline outage, or a geopolitical flare-up — the government would have fewer barrels to release to calm markets. That could amplify price swings and make it harder to prevent a spike at the pump.
Oil prices have already been volatile this year, driven by OPEC+ production cuts, strong demand from China, and renewed sanctions on Russian exports. The combination of limited spare capacity among major producers and a leaner US reserve raises the stakes for any further disruption.
For now, the market is watching whether the probability of a new record price will climb as the year wears on. The next major test will come as summer driving season pushes gasoline demand to its peak, and as traders weigh the possibility of further OPEC+ action.
