U.S. refining capacity continues to operate at high utilization as seasonal demand ramps toward the summer driving peak. National refinery utilization rates have held above 90% for consecutive weeks, indicating tight operational margins but also demonstrating the industry's ability to meet demand across a range of crude slates. Refining margins remain above seasonal averages, providing strong cash flow to operators.
Crack spreads — the difference between crude input cost and finished product output prices — favor gasoline production currently as summer grade transitions complete and driving season demand grows. Diesel cracks have moderated from recent highs but remain firm on continued global distillate demand from industrial and transportation sectors. These spreads translate directly to refiner profitability and ultimately to retail pump prices.
Crude slate flexibility has become a competitive advantage. Refineries that can process both light sweet and heavy sour grades optimize input costs by sourcing the cheapest available barrel consistent with product yield requirements. Gulf Coast refineries in particular benefit from access to Canadian heavy crude, Mexican Maya, domestic light sweet, and imported Saudi Arab Light, providing substantial optimization room against shifting price differentials.
Structural supply dynamics continue to tighten. U.S. refining capacity has shrunk modestly over the past decade as several smaller or older facilities closed while new construction has been minimal. Global refining capacity grew primarily in China, India, and the Middle East, with those Asian refiners often targeting export markets. This geographic shift in the refining industry is reshaping global product trade flows in ways that occasionally surface as pricing anomalies.
