Talk of US export ban on diesel deepens US crude futures' discount to global benchmark

The Trump administration is weighing voluntary restraint or a potential export ban on diesel to combat record-high fuel prices touching $6.514 per gallon in the United States and Europe. Spurred by supply disruptions stemming from the military conflict with Iran, skyrocketing fuel costs threaten to aggravate inflation and disproportionately impact key agricultural constituencies ahead of the November midterm elections. Simultaneously, skyrocketing maritime freight rates—with very large crude carrier transport costs from the US Gulf Coast to Asia surging from sixteen million dollars to fifty million dollars—have neutralized the arbitrage incentive typically provided by a widening WTI-Brent crude discount. Although the WTI-Brent spread has remained at a discount of four dollars or wider since July, US crude exports have stayed flat and are tracking toward their third consecutive monthly decline in September. Market analysts note that elevated logistics and war risk premiums are preventing domestic crude barrels from clearing abroad efficiently, keeping domestic inventories insulated.
