A global diesel shortage is leading to record-high prices and concerns about lasting economic impacts. On Labor Day, the national average for diesel reached $5.90 a gallon, a new record, up from $5.30 a month ago and $3.70 a year prior. Regular gasoline also hit a record for the Labor Day period at $4.15 a gallon. This unusual price surge during a time when demand typically wanes highlights the severity of the supply issues. Industry executives predict that diesel supplies will remain strained through the winter.
The shortage is attributed to several factors, including ongoing conflicts in Ukraine and Iran that have shut down refineries and disrupted supply chains. Roughly 5 million barrels per day of refining capacity have been affected. Experts like Russell Hardy, head of Vitol, estimate that the market is missing about 2 million barrels per day of oil products from Russia and another 2 million barrels per day from the Middle East. Refineries are already operating at nearly full capacity, making it difficult to increase production to meet demand.
The consequences are already being felt, with U.S. diesel prices surpassing $5.90 per gallon. In California, prices have reached $7.70 per gallon. This significant increase, almost 60% higher than the previous year, directly impacts inflation as diesel is crucial for transportation, heating, agriculture, and industrial uses. The higher fuel costs are passed on to consumers, leading to increased prices for goods and services. Goldman Sachs had previously warned that the risk of a sustained diesel shortage ahead of winter was higher than that of crude oil.
Looking ahead, leaders of major energy companies, including Mark Senn of Phillips 66, have expressed concerns about critically low diesel inventories and the prospect of sustained high prices. The situation in Europe is particularly challenging, as the region traditionally relies on diesel imports, which have already decreased significantly. The lack of refining capacity and ready diesel fuel poses a greater threat for the upcoming winter than a crude oil shortage itself, potentially leading to a decrease in global oil demand by about 1.5 million barrels per day in 2026 compared to 2025.
