The Trump administration has granted a 90-day extension to a waiver of the Jones Act (a 1920 US law requiring goods shipped between domestic ports to travel on US-flagged vessels), allowing oil, fuel, and fertiliser to move more freely within the country. The move, announced on Friday, follows an initial 60-day suspension introduced in March and is widely seen as a political response to rising fuel costs linked to the ongoing US-Israel conflict with Iran, with November midterm elections looming. Analysts, however, caution the measure is likely to have only a modest effect on consumer prices, with one estimate suggesting East Coast petrol prices could fall by just three cents per gallon, while some domestic maritime industry groups warned the waiver undermines American shipbuilding and maritime workers.
