Key Takeaways:
US crude oil inventories have plunged to multi-decade lows as the Iran war and surging export demand drain the nation's emergency stockpile.
The U.S. Strategic Petroleum Reserve fell by 5.5 million barrels to 325.7 million barrels last week, the lowest since May 1983, as the government's emergency releases to counter the Iran war supply shock deplete the nation's energy buffer.
"The SPR drawdowns have been critical in plugging the supply gap, but we're now at levels that raise questions about how much more can be released," said Carl Larry, sales manager at energy market analytics firm Enverus.
The releases are part of a U.S. agreement to sell 172 million barrels from the reserve to offset the loss of Iranian crude after the Strait of Hormuz closure. Since the war began in late February, total U.S. inventories — including commercial and SPR stocks — have fallen by 111.4 million barrels to 743.3 million barrels as of June 19, the lowest since 1984, Energy Information Administration data show.
The depleted reserve leaves the U.S. with limited firepower to combat future supply disruptions at a time when global oil markets remain fragile. With Cushing inventories at 19 million barrels — below the 20-million-barrel operational minimum — and WTI crude briefly dipping below $70 a barrel despite the tightness, the margin for error in the world's largest oil market has rarely been thinner.
Cushing Stocks Test Operational Limits
Cushing, Oklahoma — the delivery point for the WTI crude benchmark — held about 19 million barrels last week, the lowest since 2014, according to the EIA. Strong export demand from the U.S. Gulf Coast and weak flows of imported crude from Canada due to unplanned production outages have depleted volumes stored there. When oil in a tank falls below 10% to 20% of capacity, it becomes difficult to remove and raises quality concerns as water and sediments settle at the base.
"The move lower in prices is more of a continuation of sentiment sellers — money that is looking to keep pushing futures lower in hopes of finding weak support and capitalizing on the rebound," Larry said.
The Gulf Coast region, by contrast, appears relatively well supplied thanks to the SPR releases and weakening export fundamentals. Inventories along the Gulf Coast stood at about 239.8 million barrels at the end of last week, the lowest since mid-February but still above crisis levels. U.S. exports have eased to about 4.7 million barrels per day from record highs of 6.4 million bpd touched in April, analysts at Energy Aspects noted.
Global Refill Demand Looms
The drawdowns are setting the stage for a massive refill cycle. IEA member states will need to replace the 400 million barrels released in March, the biggest coordinated oil stocks release in history. India, Singapore, Australia and Pakistan are all looking to boost their reserve capacities, with plans that could require about 500 million barrels of crude and fuels to fill, according to Reuters calculations.
India, the third-biggest crude importer and not an IEA member, has asked state-owned Oil and Natural Gas Corp to build and fill a new strategic petroleum reserve site with an estimated investment of $1.6 billion. Australia plans to spend A$10 billion ($7 billion) on building its fuel stock to avoid future supply squeezes.
Saudi Arabia is also considering expanding its global oil storage capacity, Aramco Chairman Yasir Al-Rumayyan said last week. "We are thinking seriously of having larger storage facilities all over the world," he said.
Combined, the refill needs could total about 1 billion barrels spread over several years, providing a structural floor under oil prices once Strait of Hormuz traffic normalizes. WTI crude has traded as high as $119.48 since the war began but briefly fell below $70 on June 24 as revived tanker movement through the chokepoint eased supply fears.
The last time the SPR was this depleted was in 1983, when the reserve had just been established following the 1970s oil shocks — a period that ultimately led to the creation of the Strategic Petroleum Reserve itself. The current crisis has exposed how quickly even the world's largest strategic stockpile can be consumed when a critical chokepoint is blocked.
