US Strategic Petroleum Reserve Hits Lowest Level Since 1982

The US emergency crude stockpile just hit a level not seen in more than four decades. The U.S. Strategic Petroleum Reserve held 285.4 million barrels of crude oil as of the week ending September 4, the lowest level since November 1982, according to data released by the Energy Information Administration.

How deep the drawdown goes

A year earlier, the reserve held 405.2 million barrels — meaning stocks have fallen nearly 120 million barrels, or about 30%, over the past 12 months. That is one of the fastest 12-month declines on record for the SPR.

Its inventory is now less than half the approximately 700 million barrels it held near its historical peak. The SPR has an authorized storage capacity of approximately 714 million barrels, meaning the current inventory represents only about 41% of that capacity.

Why the reserve is falling

The decline follows a 172-million-barrel emergency exchange authorized by President Donald Trump as part of an international effort to stabilize oil supplies disrupted by the conflict with Iran and restrictions affecting shipments through the Strait of Hormuz.

The U.S. Department of Energy says the current program is structured as an emergency exchange, meaning participating companies are required to return crude oil to the government rather than the barrels being permanently sold from the reserve. The Department of Energy expects approximately 200 million barrels to be returned in exchange for the 172 million barrels released, potentially leaving the reserve with more oil once all contracts are completed.

Crude prices back above $100

Oil prices surged earlier this week after Saudi Arabia shut down its East-West pipeline following drone attacks, pushing Brent crude futures above $108 a barrel and West Texas Intermediate futures above $103 a barrel — the first time U.S. crude had traded above $100 since May.

Separately, a 60-day ceasefire between the U.S. and Iran expired in August without a permanent agreement, adding further upward pressure to oil markets.

Refineries running hot, production at record

U.S. refineries processed 17.6 million barrels per day during the week ending September 4, up 91,000 barrels per day from the prior week, at 97.8% capacity utilization, according to the EIA.

The U.S. Energy Information Administration expects American crude production to average a record 13.8 million barrels per day in 2026, surpassing the previous record established in 2025. High domestic production reduces America’s exposure to imported crude, but it does not eliminate the need for the SPR.

Options market and stocks to watch

With crude back above $100 and the SPR cushion thinning, energy names are back in focus. Watch for flow in:

XOM: Exxon Mobil benefits directly from sustained triple-digit crude, watch call flow on any Iran headline.

CVX: Chevron trades similarly on Brent strength, watch for skew changes if the Strait of Hormuz situation escalates.

USO: The oil ETF is the cleanest way to track WTI moves, watch for gamma exposure shifts near round-number strikes.

XLE: Broad energy exposure, watch for sector rotation flow if crude holds above $100.

OXY: US shale leverage makes this a high-beta play on domestic production, watch for unusual call activity.
