Strategic Petroleum Reserve (SPR) inventories have been climbing for more than a year, but they could go much higher if President Trump has his way, as one of his major campaign promises was to refill the SPR “to the very top,” a goal he has repeated since his return to the Oval Office. Current inventories sit just below 400 MMbbl, leaving the SPR about 320 MMbbl shy of maximum capacity. But the refilling process may not be as straightforward as one might think, as three of the four SPR storage sites have experienced construction upgrades in the last year — which means things could go slower than anticipated. In today’s RBN blog, we’ll discuss the challenges of filling up the SPR and detail four scenarios for how the process might play out.
