America's Oil Reserve Was Lent, Not Spent

Department of Energy data released August 10 shows Strategic Petroleum Reserve crude stocks fell 6.1 million barrels to 298.7 million, the lowest level since January 1983. That is the nineteenth consecutive weekly drawdown. The reserve held approximately 415 million barrels in early March and has shed roughly 116 million since the conflict began February 28. The all-time record low is 270.5 million barrels, set in 1982. Total US oil inventories including commercial stocks fell to 730.8 million barrels in early July, the lowest since 1984. The drawdown stems from a coordinated release announced March 11, committing 172 million US barrels as the American portion of an IEA-coordinated 400 million barrel action across 32 member nations. Unlike previous SPR drawdowns, this release is structured as an exchange: companies borrow SPR crude and return the original volume plus a premium at a later date. The Department of Energy has awarded more than 133 million barrels across a rapid series of solicitations since mid-March, securing return premiums ranging from 18 percent to as much as 28 percent on individual tranches. Energy Secretary Chris Wright said in March that for every barrel released, "we're going to get back more than 1.2 barrels of oil that will go back into the reserve next year."

Almost every account of the SPR treats it as a tank being emptied. That framing produces the wrong worry and misses the real one. The barrels were not sold. They were loaned, at what looks on paper like an excellent price. Return 1.2 barrels for every one taken, and the reserve ends up larger than it started. The Energy Secretary has said as much publicly. The question nobody is asking is why a refiner would agree to that. The answer is the shape of the futures curve. In steep backwardation — where oil for delivery today costs more than oil for delivery next year — borrowing a barrel now and returning it later is enormously profitable. You sell the borrowed crude at today's high price, and when the obligation comes due you buy replacement barrels at tomorrow's lower price. The 18 to 28 percent premium is not a penalty. It is what borrowers are willing to pay for the privilege, and the size of it tells you how steep the curve was when those deals were struck. Which means the reserve's rebuild is not a policy commitment. It is a trade, and it only pays if the curve stays where it is. Flatten the curve and the economics narrow. Flip it to contango, where future oil costs more than today's, and returning 1.2 barrels becomes a losing proposition. Obligations that looked like free money get renegotiated, deferred, or quietly restructured. The barrels do not come back on schedule, and they may not come back at the promised ratio. Here is what makes that more than a technical footnote. Every major forecast currently on the record calls for exactly the condition that breaks these trades. Fitch expects Brent at $70 by the fourth quarter and the market returning to oversupply from September. The Treasury Secretary says the Strait of Hormuz becomes irrelevant within two years, with pipelines carrying most of what now transits it. Both of those are forecasts of a market where crude gets cheaper and more available going forward — which is contango, and which is the environment in which the SPR does not get refilled. So the two positions cannot both be comfortable. If oil normalizes, the reserve stays near a forty-three-year low with its restocking mechanism impaired. If oil stays tight enough for the exchanges to unwind profitably, the physical scarcity that emptied the reserve in the first place has not been solved. Meanwhile the physical evidence keeps pointing one direction. Kpler counted confirmed Hormuz crossings falling from fifteen on Friday to eleven Saturday to six Sunday, while the Iran-Oman corridor negotiation was reportedly close to agreement. ADNOC has disclosed fifteen of its vessels attacked since the conflict began, three of them in a single week. US imports of Saudi crude hit zero in July, the first full month since 1985. Aramco's chief executive estimates flows at roughly a tenth of pre-conflict levels and up to eighteen months to refill inventories even if the strait opened today. Against that, twenty-eight million barrels of cushion and a rebuild that depends on the market disagreeing with itself.
