Diesel Prices Reach Record Highs Amid Refining Bottlenecks and Global Disruptions
The price of diesel fuel has reached record highs in some parts of the United States, with the national average at around $6.50 per gallon and California above $8.40. This has led to claims that refiners are gouging consumers by keeping crude oil prices low while raising diesel prices.
However, an examination of the refining process reveals a more complex picture. Crude oil is not interchangeable with diesel fuel, which is a manufactured product. The refining system plays a critical role in converting crude into usable fuels, and right now, it's facing bottlenecks that are driving up prices.
The diesel crack spread, which measures the difference between the market value of diesel and the crude oil used to produce it, has reached record highs. In mid-August, it topped $100 per barrel for the first time, and Asian diesel refining margins have risen above $87 per barrel. These high spreads indicate that refined-product supply has become tight, leading to higher prices.
The current market is characterized by a shortage of available diesel relative to demand, exacerbated by disruptions in global supplies. Ukrainian drone attacks on Russian refineries have reduced output and restricted fuel exports, while the Middle East conflict has damaged refining infrastructure and constrained shipping through the Strait of Hormuz.
