US oil refiners are ramping up fuel production to help fill supply gaps for gasoline, diesel and jet fuel as the Iran war chokes off Persian Gulf energy supplies.

The brisk pace is expected to push many refineries to their effective maximum capacity for at least the rest of 2026, analysts said. Shrinking backup supplies in Europe and elsewhere, coupled with little prospect of restoring war-damaged Middle East infrastructure any time soon, are swelling crude-processing margins.
