US refiners are operating at near-record levels, producing an average of 5.3 million barrels of distillate fuel oil (predominantly diesel) per day this month. This pace, if sustained, would mark the highest July output ever and one of the highest on record outside the winter heating season. This aggressive production schedule is a response to a severe global supply crunch driven by renewed fighting in the Middle East, threatening shipments through the Strait of Hormuz, and Russia's ban on most fuel exports following Ukrainian drone strikes on its refineries. Normally, diesel production peaks later in the year, but the current geopolitical climate has forced an early ramp-up.
Despite the increased production, US diesel stockpiles remain below average, raising concerns about supply tightness as colder months approach. As of July 22, US diesel futures traded near $4.10 a gallon, and European diesel prices were around $1,224 a ton, both at two-month highs. Analysts anticipate further market tightening due to upcoming weather-related risks in the US and the global refinery maintenance season. James Noel-Beswick, head of commodities at Sparta Commodities, expressed skepticism about building sufficient diesel stock before a large period of global turnarounds from September and the winter of Q1 2027.
The heightened demand for diesel has led to significant profitability for refiners. The benchmark US 3-2-1 refining margin, or crack spread, recently surged to a record high of nearly $70 a barrel. European diesel margins have also jumped to a record of approximately $65 a barrel. These extraordinary premiums indicate intense competition among consumers for scarce fuel supplies. Diesel, a critical component of the global economy, is currently retailing above $5 a gallon, while gasoline prices have climbed above $4 a gallon, fueling inflation concerns and creating political challenges ahead of the midterm elections.
