The US Treasury Secretary has warned that Oman could face sanctions if it assists Iran in implementing a toll system in the strategic Strait of Hormuz. In a post on social media platform X on Thursday, the Secretary stated that the US Treasury would target any party directly or indirectly involved in establishing such a system, emphasizing that Washington would not tolerate any attempt to impose tolls in the vital maritime route.

Later at a White House press conference, the Secretary said he had spoken with Oman’s ambassador earlier that morning. According to him, the ambassador assured that Oman has no plans to introduce any tolls in the Strait of Hormuz. The warning follows ongoing US concerns about potential disruptions to international shipping through the waterway.

The statement underscores Washington’s intent to deter regional actors from supporting measures that could affect global trade through the Strait, one of the world’s most important oil transit routes.
