U.S. diesel fuel exports climbed to an all-time high last week, fueled by global shortages stemming from the ongoing energy crisis in the Middle East.

According to data from the Energy Information Administration (EIA), the United States exported diesel at a rate of 1.9 million barrels per day last week, surpassing the previous record set earlier in the spring. However, the same EIA report indicated that domestic diesel production declined during the week, as did inventories of the fuel. U.S. diesel stockpiles now sit 12% below the five-year average.

The bulk of American diesel exports are flowing to Europe, where fuel supply is particularly tight. The shortfall has been exacerbated by a decline in local refining capacity, as European governments push an energy transition agenda centered on the mass electrification of transportation. That transition has yet to meaningfully reduce fuel demand, despite a substantial rise in electric vehicle sales across the continent, particularly within the European Union. The United States has emerged as a critical supplier of refined products to global markets over the past decade, as the shale boom boosted domestic crude output and Gulf Coast refiners invested heavily in export infrastructure to serve growing international demand.

Bloomberg reported that U.S. diesel exports had been running at approximately 1.5 million barrels per day for five consecutive weeks before climbing to the record high. With refineries unable to increase output further, fuel sellers have been drawing down inventories to meet export demand. According to Bloomberg, domestic diesel stockpiles have fallen to their lowest levels since 1996.

The situation poses potential challenges for the domestic U.S. market as the heating season draws near. Diesel is a key feedstock for heating oil, which is widely used in the Northeastern United States during the winter months—the region accounts for the vast majority of the country's heating oil consumption. Heating oil is also in high demand in other regions globally, meaning that demand for an already scarce commodity is set to rise in the coming months—at the same time that production is expected to dip as refineries enter maintenance season. Diesel is also critical to the broader U.S. economy beyond heating, powering the freight trucks, trains, and vessels that move the majority of goods, as well as agricultural machinery essential to the fall harvest season.

Refinery maintenance season typically runs from August through October. While it can be delayed if necessary, doing so may be unwise given that refineries are already operating at above-normal utilization rates.
