The United States and Iran both claim guardianship of the Strait of Hormuz as they struggle for control over the narrow waterway [1].
Control of the strait is strategically vital because it serves as a primary chokepoint for global oil shipments. The U.S. seeks to assert dominance to protect international shipping and pressure the Iranian government, while Iran aims to leverage the waterway to enforce its own routing requirements [1, 3].
The conflict has created a contested environment where neither side holds absolute authority. The U.S. has attempted to reopen the waterway and re-impose a blockade [1]. However, Iran continues to attack vessels that do not follow routes preferred by Tehran [2].
Logistical challenges complicate U.S. efforts to restore stability. Military analysts said that restoring pre-war traffic levels would require the deployment of tens of thousands of American troops [3]. This scale of mobilization presents a significant hurdle for the current administration.
Financial measures have also been a point of contention. Reports indicate that President Donald Trump previously said the U.S. would reimpose a blockade and charge fees on shipping [1]. While some reports mentioned a proposed shipping fee of 20% of costs [2], other reports said that President Trump has since called off that specific fee [2].
The Strait of Hormuz remains a volatile flashpoint between Oman’s Musandam Peninsula and the coast of Iran [1, 4]. As both nations claim the right to regulate the passage, the risk of naval confrontations remains high.
“The US and Iran both claim guardianship of the Strait of Hormuz.”
The competing claims of authority over the Strait of Hormuz signal a shift from diplomatic tension to a direct struggle for maritime hegemony. Because the waterway is essential for the global energy supply, the inability of the U.S. to decisively secure the route—or Iran's refusal to permit free passage—creates a persistent risk of global economic volatility and unplanned military escalation.
