President Trump said Friday that the United States intends to declare the Strait of Hormuz US territory once the war with Iran concludes, telling supporters in New York: “After we finish defeating Iran, which is being very badly defeated — pretty soon I'll be declaring the Hormuz Strait a territory of the United States.” The remarks give no legal or procedural detail on how such a declaration would work, but they land at a moment when control of the waterway is already a central sticking point in ceasefire talks between Washington and Tehran.
The Strait of Hormuz is the narrow channel between Iran and Oman through which roughly a fifth of global oil consumption and a substantial share of global liquefied natural gas exports pass each day, making it one of the most closely watched chokepoints in global commodity markets. Iran has restricted traffic through the strait amid the conflict, a move that has already pushed shipping and insurance costs higher for tankers transiting the region.
Iran's Response and the Ceasefire Backdrop
Iran's government rejected the claim outright. Deputy Foreign Minister Kazem Gharibabadi said the waterway will remain Iranian and that Tehran's blockade enforcement would continue until the US accepts what he characterized as defeat — rhetoric that suggests any US move to formally claim the strait would face active resistance rather than a negotiated handover. The statement adds a new and unusually concrete flashpoint to ceasefire negotiations that had already been complicated by disputes over troop withdrawals and sanctions relief.

For commodity and shipping markets, the specific legal mechanism Trump has in mind matters less than the signal that US control over Hormuz — rather than merely naval protection of transit rights — is now part of the administration's stated endgame for the conflict. Sustained restrictions or an escalation around the strait would have outsized implications for oil prices and tanker insurance rates well beyond the immediate region, given how few alternative routes exist for Gulf oil exporters to reach global markets.
Whether the declaration amounts to a serious policy shift or rhetorical positioning ahead of further negotiations remains to be seen. Trump gave no timeline beyond “pretty soon,” and any formal move to claim foreign sovereign waters as US territory would raise significant questions under international law that go well beyond what a campaign-style remark can resolve on its own.
