President Donald Trump's administration has extended a limited Jones Act waiver for another 90 days, allowing foreign-flagged vessels to carry a narrower set of energy and industrial cargoes between U.S. ports as fuel supply disruptions linked to the Iran war continue to pressure markets. The latest renewal, due to run until mid-November, replaces broader relief with a voyage-by-voyage approval process under which foreign ships must obtain case-by-case approval and the Pentagon must review each voyage in consultation with the U.S. Maritime Administration. Trump initially issued a 60-day waiver in March to ease surging fuel and fertilizer prices and extended it again in May. White House Deputy Press Secretary Taylor Rogers said the policy is intended to preserve access to critical resources for the military and key industries and has increased domestic deliveries of gasoline, diesel and jet fuel. Maritime Administration data cited in the report show 210 otherwise-prohibited voyages have been completed since the waiver began, transporting nearly 55 million barrels of cargo, mostly gasoline and crude oil. Analysts remain divided over the policy's impact: supporters say it has helped soften supply disruptions tied to the Strait of Hormuz, while critics argue it cannot address deeper shortages and risks weakening protections for the domestic maritime industry.
