Former US President Donald Trump's proposal to ban diesel exports, aimed at lowering record-high domestic prices, is largely viewed by analysts and market watchers as a counterproductive measure. While some Republican lawmakers support the ban to alleviate pressure on farmers and truckers, experts warn it would exacerbate global supply issues and could even lead to higher domestic prices in some regions. Average US diesel prices have reached a record $6.5107 per gallon, underscoring the political pressure for action.
Analysts from Reuters, the Atlantic Council, Foreign Policy, and FreightWaves agree that a ban would create more problems than it solves. The US exported a record 1.6 million barrels per day of diesel in August. A ban could force US refineries to reduce output, increase global diesel prices by up to 100%, and deepen Europe's existing shortages, straining international relations.
Domestically, the impact would be mixed at best. While Gulf Coast and Midwest consumers might see a temporary price dip, West Coast regions reliant on imports could face higher prices due to increased global competition for a smaller supply. Furthermore, a ban could disrupt supply chains in Latin American countries like Mexico, which depend on US diesel for agriculture, potentially leading to higher grocery prices for American consumers.
Experts also highlight that restricting exports would remove a key incentive for refiners to maintain high output, as profitable export markets drive current capacity utilization. Reducing these margins could lead to refinery run cuts, impacting not only diesel but also gasoline, jet fuel, and heating oil supplies. The US refinery complex is also designed to process heavy, sour crude, and an export ban could lead to bidding wars for such crude or force refiners to use suboptimal feedstocks, further hindering efficiency.
Overall, the consensus among financial analysts is that a US diesel export ban would disrupt global markets, create regional price disparities within the US, reduce refinery output, and potentially lead to higher food prices, without achieving its stated goal of broadly lowering domestic diesel costs. Bob McNally, former White House energy advisor, noted that while the U.S. Gulf Coast might see a temporary pump price dip, it would come "at the cost of likely higher coastal prices [elsewhere] and eventually, higher prices for everyone as investment gets scared away."
