President Donald Trump has repeatedly floated the idea of renaming the Strait of Hormuz the “Strait of Trump” or “Trump Strait,” most recently in a September 2, 2026, Truth Social post amid U.S.-Iran clashes, and earlier in speeches and map shares. He has followed through on similar domestic renamings, such as the Gulf of Mexico to the Gulf of America and Lake Ontario to Lake America, via executive order directing federal agencies to update the Geographic Names Information System. However, the Strait of Hormuz is an international waterway subject to the UN Convention on the Law of the Sea and shared sovereignty involving Iran and Oman, placing it beyond unilateral U.S. federal authority. Trump later described the suggestion as merely “thrown out there,” and no executive action or formal process has advanced. With the December 31 deadline approaching and no binding steps taken, traders assign overwhelming probability to the outcome not occurring.
