Axios with the info. Trump is considering extending the Jones Act waiver after it boosted U.S. oil shipments by 70% and eased fuel costs, with over 9 million barrels moved by foreign tankers since March.Summary:Trump considering extending Jones Act waiverWaiver introduced to ease fuel costs during Iran warForeign tankers boosted domestic fleet by ~70%Over 9 million barrels shipped under waiverAlaska sees significant fuel supply benefitDebate pits cost efficiency vs domestic industry protectionNo final decision yet on extensionThe Trump administration is weighing an extension of its temporary waiver of the Jones Act, after early data showed the move has significantly boosted domestic oil shipments and eased fuel cost pressures during the Iran war.The Jones Act, a century-old U.S. maritime law, requires goods transported between U.S. ports to be carried on American-built and flagged vessels. While designed to support domestic shipping and shipbuilding industries, the rule has long been criticised for increasing transport costs due to a limited supply of eligible vessels.In response to rising fuel prices linked to Middle East tensions, President Trump introduced a 60-day waiver on March 18, allowing foreign-flagged tankers to move oil between U.S. ports. The policy shift has materially expanded available shipping capacity, with White House data showing around 40 additional tankers have entered the domestic trade, effectively increasing the fleet by roughly 70%.Since the waiver took effect, foreign vessels have transported at least 9 million barrels of oil across key domestic routes, including from California to Texas, Florida and Alaska. Officials say the impact has been particularly notable in Alaska, where imported jet fuel under the waiver accounts for roughly half of the state’s typical monthly consumption.The administration views the waiver as a tool to mitigate supply bottlenecks and stabilise fuel prices during a period of heightened geopolitical risk. One adviser said the president has responded positively to the results so far and is open to maintaining the waiver for as long as Iranian-related disruptions continue to pressure energy markets.However, the policy remains politically contentious. Critics of the Jones Act, including libertarian groups, argue the law is outdated and unnecessarily inflates costs across the U.S. economy. Supporters, including protectionist and national security advocates, counter that the legislation is essential for maintaining a domestic maritime industry and safeguarding jobs.The debate reflects a broader tension between economic efficiency and strategic resilience. While the waiver has delivered short-term benefits in terms of increased supply and reduced transport costs, extending it could face pushback from stakeholders concerned about long-term impacts on U.S. shipping capacity and employment.For now, the White House has not made a final decision on whether to prolong the waiver, but officials emphasise that the initial data points to improved supply flows and faster delivery of energy resources across the country.
