President Trump's repeated suggestions to rename the Strait of Hormuz the "Trump Strait," including recent Truth Social posts and remarks at the September 2026 Republican midterm convention, have occurred amid ongoing U.S.-Iran hostilities over the waterway. These comments align with prior executive orders renaming U.S. domestic features such as the Gulf of Mexico and Lake Ontario, yet they remain framed as rhetorical or provisional, with the president later describing one proposal as merely "thrown out there." International straits fall outside unilateral U.S. naming authority under global conventions, requiring broad diplomatic acceptance that has not materialized. No formal executive action, legislative steps, or international coordination has advanced the change by mid-September 2026, supporting trader consensus that completion by year-end faces substantial procedural and geopolitical barriers.
