US Emergency Oil Reserves Hit Lowest Level Since 1982 as Brent Crude Holds Above $115

Key takeaways

• US emergency oil reserves fall to 282.6 million barrels
• Brent crude remains above $115 despite peace efforts
• Washington authorizes another emergency release for Louisiana refinery

America's emergency oil stockpile has fallen to its lowest level in 44 years, leaving the United States with a shrinking supply buffer as Brent crude remains above $115 per barrel and Middle East disruptions continue threatening global energy markets.

The Strategic Petroleum Reserve (SPR) declined to 282.6 million barrels during the week ending October 23, its lowest reading since October 1982, according to Department of Energy data.

The latest decline comes as Washington authorizes additional emergency oil supplies and traders weigh whether diplomatic efforts can contain the energy crisis.

US Oil Reserves Fall to 44-Year Low

The SPR is designed to protect the United States against severe oil supply disruptions, but months of withdrawals have substantially reduced its available inventory.

The reserve held approximately 415 million barrels before the Iran conflict began in February, meaning inventories have declined by roughly 133 million barrels since then.

Washington committed to releasing 172 million barrels under an international emergency response, including an additional 40-million-barrel offer announced in September.

Unlike permanent sales, the current exchange arrangements require participating companies to return borrowed crude later, generally with additional barrels as compensation.

However, replenishment can take substantially longer than withdrawals, leaving the country exposed to further disruptions before the stockpile recovers.

The Department of Energy also authorized an emergency exchange of up to 400,000 barrels to address a supply interruption affecting Phillips 66's Lake Charles refinery in Louisiana.

That operation demonstrates how emergency inventories are being used for individual refinery disruptions as well as broader international supply shocks.

The latest figures reinforce earlier warnings from Saudi Aramco that global oil inventories could require years to rebuild.

Brent Oil Holds Above $115 as Middle East Risks Persist

Brent crude settled Monday at $115.81 per barrel, declining 0.8%, while US West Texas Intermediate closed at $101.76.

Oil retreated on hopes of diplomatic progress involving Iran, although continued threats to Saudi energy infrastructure and regional shipping prevented a larger decline.

Recent attacks and shipping disruptions have kept transportation costs elevated, even as Middle Eastern crude exports recover.

The resulting uncertainty has created a substantial premium in oil markets.

JPMorgan recently estimated Brent's fundamental value at approximately $94, suggesting a geopolitical premium exceeding $20 per barrel.

That estimate reflects the bank's supply-and-demand model rather than a prediction that crude prices will immediately retreat to $94.

The International Energy Agency has also coordinated emergency reserve releases to offset disruptions, but restoring physical supply has not eliminated the market's risk premium.

What Happens If Oil Prices Keep Rising?

Further supply interruptions could place additional pressure on the already depleted SPR, particularly if regional shipping routes face renewed attacks.

Higher crude prices are also affecting consumers. Average US gasoline prices recently reached approximately $4.29 per gallon, increasing household transportation costs and complicating the inflation outlook.

Meanwhile, Washington has explored alternative fuel supplies, including Russian diesel imports, to ease shortages.
