U.S. crude inventories are recovering from the January winter storm and are once again near the five-year average for this point in the year. A key reason for the rapid recovery in inventory has been very low refinery throughput.
Refinery throughput dropped sharply in January as frigid temperatures from the winter storm impacted operations. Spring is the typical maintenance season for refiners as they try to optimize operations heading into the high-demand summer period for refined fuels. After the winter storm negatively impacted operations, many decided to move up maintenance work rather than going through restarting and shutdown processes again.
