The Department of Homeland Security has issued the broadest Jones Act waiver since at least the 1950s, just weeks after the US-Iran conflict erupted. The Cato Institute's Jones Act Waiver Tracker shows that nearly 50 million barrels have been moved since the waiver took effect on March 17. After 135 days, waiver shipments to the West Coast totaled 13.9 million barrels, equivalent to 108% of the region’s projected full-year baseline. Puerto Rico received 5.02 million barrels, equal to 134% of its normal annual pace, while New England’s 1.25 million barrels represented an increase of 215%. The data suggest the waiver is unlocking trade routes that were previously uneconomical or unavailable under Jones Act restrictions.
