U.S. commercial crude oil inventories excluding the Strategic Petroleum Reserve (SPR) have declined by more than 45 million barrels over the past 19 weeks, according to American Petroleum Institute (API) data. The drawdowns have been offset by releases from the SPR, which held 289.7 million barrels as of the week ending August 21, a level 442 million barrels below maximum capacity.
The SPR’s current inventory is approaching the generally accepted operational minimum of 250-300 million barrels, a range below which the reserve may face challenges in efficiently pumping and processing oil. In the latest week, another 3.7 million barrels were withdrawn from the SPR to support commercial inventories, following a 328,000-barrel decline in the prior week.
