KEY TAKEAWAYS: The Trump administration may issue a temporary waiver of the Jones Act to ease domestic fuel shipments. Waiver would allow foreign-flagged vessels to transport fuel between U.S. ports. The move responds to rising fuel prices amid the U.S.-Israeli conflict with Iran. Previous wai vers were issued after hurricanes to address supply disruptions in 2017.   The Trump administration has told U.S. oil companies and shipping groups to prepare for a potential waiver of the century-old Jones Act governing domestic shipping to ease movement of fuel around the country, two sources familiar with the discussions told Reuters. The announcement could come as early as Thursday, the sources said, and would be aimed at combating spiking fuel prices since the start of the U.S.-Israeli war on Iran. The White House did not immediately comment. Under the Jones Act, goods shipped between U.S. ports must be carried on vessels that are U.S.-built, U.S.-flagged and mostly U.S.-owned. The requirement sharply limits the number of tankers available for domestic shipments. Waiving the rule temporarily would allow foreign ships to carry fuel between U.S. ports, potentially lowering shipping costs and speeding deliveries The United States has issued Jones Act waivers in the past only sparingly, typically in response to major supply disruptions. The most recent waivers came after hurricanes such as Hurricane Harvey and Hurricane Maria in 2017. At the time,  the U.S. Department of Homeland Security temporarily allowed foreign-flagged vessels to transport fuel between U.S. ports to ease shortages and speed deliveries to affected regions.  (Reporting by Jarrett Renshaw; Editing by Richard Valdmanis and Chizu Nomiyama) ...read more read less
