US Energy Secretary Wright says SPR will exceed 300 million barrels by end of Iran conflict
The strategic petroleum reserve has been drained by roughly 100 million barrels since the Iran crisis began, but a zero-cost replenishment plan is already in motion.
US Energy Secretary Chris Wright confirmed that the Strategic Petroleum Reserve currently holds approximately 300 million barrels, down from around 400 million before the US-Israeli conflict with Iran disrupted oil flows through the Strait of Hormuz. Wright said the reserve will grow beyond that 300 million barrel mark once the conflict ends, thanks to a repayment structure that doesn’t require additional taxpayer funding.
What the drawdown actually looks like
Since the Iran conflict escalated in late February 2026, the US government has released 172 million barrels from the SPR to offset supply disruptions. SPR inventories dropped from roughly 349 million barrels in June 2026 to somewhere between 298 and 305 million barrels by August 2026.
To put 300 million barrels in perspective: the SPR’s capacity is around 714 million barrels. The current stockpile represents less than 42% of what the salt caverns along the Gulf Coast can actually hold. At peak levels in 2010, the reserve held nearly 727 million barrels.
Wright framed the drawdown as a necessary response to real supply disruption. The Strait of Hormuz, through which roughly a fifth of the world’s oil passes on any given day, has been a chokepoint in both the literal and strategic sense since the conflict began.
The replenishment math
The plan to rebuild the SPR relies on exchange agreements with commercial oil companies rather than open-market purchases. Under these deals, companies borrow oil from the reserve during tight supply periods and are required to return 1.25 barrels for every barrel they take. The estimated net addition from these repayments is around 40 million barrels, which would push the reserve above 340 million barrels once all the oil comes back.

Wright also highlighted the role of the US military in maintaining oil flows from the Persian Gulf. He noted that military operations have enabled approximately 7 million barrels per day of oil to exit the Gulf.
Why 300 million barrels matters
At current US oil consumption rates of roughly 20 million barrels per day, 300 million barrels represents about 15 days of total national demand. The International Energy Agency recommends that member nations hold at least 90 days of net import coverage.
Energy investors should note that the 7 million barrels per day flowing out of the Gulf with military assistance represents a fragile equilibrium. Any escalation that disrupts that flow could trigger another round of SPR releases, pushing the reserve even lower.
