Trump administration extends limited Jones Act shipping waiver to help keep oil moving as Strait of Hormuz reopening talks stall

President Donald Trump’s administration has extended a limited waiver tied to the Jones Act to support continued U.S. oil movement, according to CNBC. The extension comes as the administration’s most recent efforts to advance a deal aimed at reopening the Strait of Hormuz have not produced the expected breakthrough, leaving supply-route uncertainty in place.

The Jones Act is a U.S. maritime cabotage law that generally limits domestic shipping between American ports to vessels that meet specific U.S.-linked requirements. Waivers can temporarily adjust those constraints in response to national economic or security concerns, affecting what types of ships can carry cargo on certain U.S. routes during the waiver period.

CNBC reported that the administration’s decision reflects an effort to reduce operational bottlenecks that can occur when shipping options become constrained by security risks and global market disruptions. In that frame, officials are using the waiver authority to preserve practical logistics for bringing petroleum-related cargoes into and within the United States.

The waiver extension is also tied, in the reporting, to the Iran-related conflict and the strategic significance of the Strait of Hormuz, a key chokepoint for energy shipments. CNBC said the administration had shown signs of progress toward a reopening outcome, but that the latest attempt did not materialize, prompting a renewed emphasis on near-term measures to keep oil flowing despite the continued risk environment.

While the reporting describes the policy goal and timing, it does not provide in the available summary the specific legal instrument, the waiver’s start and end dates, or the exact scope of routes and cargoes covered. As a result, the precise operational parameters of the extension are not confirmed beyond the general characterization of a limited Jones Act waiver.

The practical effect of such waivers is typically measured by whether regulated shipping capacity can be maintained when customary routes or vessel availability are disrupted. For the Trump administration, keeping energy logistics steady can influence downstream costs and supply reliability, even as the waiver remains a targeted, temporary modification rather than a permanent change to maritime law.
