US Crude and Product Inventories Rise, Signaling Potential Demand Shifts

United States crude oil inventories increased by 2.0 million barrels in the week ending July 17, according to the U.S. Energy Information Administration (EIA). This build brings commercial crude stockpiles to 411.7 million barrels, which remains 6% below the five-year average for this period. The EIA's official figures largely align with earlier data from the American Petroleum Institute (API), which had reported a 2.603 million barrel rise in crude inventories. Beyond crude, petroleum product inventories also experienced widespread increases. Gasoline stocks rose by 2.0 million barrels, with current levels 5% below the five-year average. Distillate fuel inventories, which include diesel and heating oil, saw an even more significant increase of 4.8 million barrels, though they remain 10% below the five-year average. Propane/propylene inventories grew by 2.7 million barrels, now 1% below the five-year average. Refinery utilization rates decreased by 1.1 percentage points, settling at 91.1% of total capacity. This decline in utilization, coupled with the across-the-board inventory builds, suggests a potential moderation in refining activity or a weakening of product demand, particularly for gasoline and distillates. Total motor gasoline demand, measured by product supplied, averaged 9.1 million barrels per day over the past four weeks, an increase of 0.2% compared to the same period last year. Similarly, distillate fuel product supplied averaged 3.8 million barrels per day, down 0.4% from the same period last year. The simultaneous increase in crude and product inventories, alongside a dip in refinery runs, indicates a complex interplay of supply and demand dynamics in the U.S. energy market. While overall inventory levels remain below historical averages, these builds warrant close monitoring for their implications on future oil prices and refinery margins.
