Strategic petroleum reserves being rapidly drawn down, with both current effectiveness and future potential approaching their limits

The strategic petroleum reserve (SPR) initially held approximately 415 million barrels. If the 172 million barrels borrowed are fully returned—plus roughly 40 million barrels in interest—the total reserve would reach about 455 million barrels. This is our rough estimate assuming all goes smoothly; even so, it implies the SPR would stand at only about two-thirds of the Department of Energy’s stated effective storage capacity of roughly 680 million barrels. Further expansion would require purchasing crude oil. The U.S. Department of Energy estimates that restoring the reserve to its effective peak level—requiring roughly 250 million additional barrels—would cost approximately $20 billion at a price of about $80 per barrel. Under the 2025 Appropriations Act, Congress allocated $171 million for crude purchases—enough to acquire roughly 2 million barrels. As of May 2026, the Department of Energy has used this funding to sign a contract for 1 million barrels. The U.S. government is considering supplementing the reserve with Venezuelan crude—a move aligned with Washington’s growing control over Venezuela’s oil fields. Yet a key challenge lies in the crude’s chemical properties: Orinoco crude has an API gravity of 9.5–12°, while Venezuela’s primary export grade, Merey 16, registers 16° API. In 2016, the Department of Energy informed Congress that it does not store crude heavier than 22.3° API due to operational difficulties far outweighing any benefits. Thus, for this particular reserve swap, the claim that “taxpayers bear no cost” holds true. For the SPR as a whole, the outlook remains cautiously optimistic. Eventually, someone will need to pay for the remainder—and that bill does not appear in the current federal budget. What if reserves must be released again? Gulf oil exports have rebounded to 81% of pre-war levels, yet tanker attacks persist and Brent crude prices have surged above $100 per barrel. A Dallas Fed survey found petroleum industry executives most frequently cite Q2 2027 as the timeframe when Gulf exports will fully normalize. On October 2, the G7 agreed to release another 100 million barrels of crude and diesel over four months—following the International Energy Agency’s record-setting action in March. Global inventories have been severely depleted after eight months of conflict. The SPR serves not only wartime needs: its 60 salt-cavern storage sites lie along the coasts of Texas and Louisiana—a region currently preparing for an approaching hurricane. After Hurricane Katrina in 2005, the SPR released 11 million barrels. The smaller the reserve, the weaker the buffer against domestic disasters. Moreover, replenishing the SPR also affects oil prices. Replenishment adds new demand. In August, PVM Oil Associates estimated that refilling 200 million barrels over two years would mean roughly 280,000 barrels per day flowing into the SPR—nearly 3% of U.S. oil consumption—likely pushing up the WTI futures curve. The Atlantic Council put it more bluntly: if the conflict remains unresolved, there simply isn’t enough crude available to refill the reserve without triggering another round of price increases.

Iran’s pursuit of 'unilateral control' over the Strait of Hormuz: rejecting joint mine-clearing efforts and asserting authority to levy transit fees

On the 29th, Trump posted on social media that Iran had requested talks, stating, “Talks will take place tomorrow in Doha,” and reiterated, “Iran will not possess nuclear weapons.” However, Iranian Foreign Ministry Spokesperson Nasser Kanaani clarified the same evening that Iran has no plans for negotiations with the U.S. in the coming days. According to the Iranian Foreign Ministry, Iran will indeed dispatch an expert delegation to Doha—but solely to follow up on implementation of the Islamabad Memorandum of Understanding, with no connection to the U.S. delegation’s visit to Qatar. Kanaani noted that under Article 13 of the Memorandum, final agreement negotiations may commence only after Articles 1, 4, 5, 10, and 11 have begun implementation and are sustained. Negotiations on a final agreement have therefore not yet commenced. He added that Iran is monitoring the implementation of two U.S. commitments: permitting Iranian crude exports (Article 10) and unfreezing Iranian frozen assets (Article 11). The U.S. has already issued the necessary licenses for crude exports. The Strait of Hormuz Control Dispute: Fee Threats and Mine-Clearing Sovereignty Control over the Strait of Hormuz has emerged as one of the most sensitive structural disputes in current negotiations. The existing interim agreement stipulates that Iran will refrain from imposing transit fees on passing vessels for 60 days—but explicitly preserves its right to impose such fees thereafter. The U.S., Europe, and Gulf Arab states have all clearly opposed Iran’s fee plan. Once the 60-day window expires, whether Iran implements the fee will directly impact global energy trade. Prior to the outbreak of conflict, this waterway carried approximately one-fifth of the world’s crude oil and liquefied natural gas shipments. On mine clearance, Iran has firmly rejected multilateral involvement. Earlier on the 29th, Macron announced that France and Oman, together with partners, would jointly conduct mine-clearance operations in the Strait of Hormuz to ensure safe and free passage. The Iranian Foreign Ministry swiftly rejected the proposal in an official statement, describing the regional situation as “sensitive and complex,” and strongly advising France against actions that could further complicate matters through “provocative behavior.” Tanker Passage: Markets Maintain Cautious Optimism Despite the complexity, tanker operators and crews continue transiting the Strait of Hormuz—providing some market support. According to Bloomberg, two vessels were attacked during heightened weekend hostilities, including a fully laden very large crude carrier (VLCC); Strait traffic briefly slowed as a result.

The Oil Market Is Brimming With Crude Despite Tanker Attacks

Despite ongoing tanker attacks near the Strait of Hormuz, global oil markets remain well-supplied due to increased OPEC+ production and record US output. The IEA reported supply outpacing demand recently, pushing Brent crude prices below $90.
