Why the Strait of Hormuz is impassible, and what the U.S. is doing about it
By Easton Martin | March 11, 2026
The Strait of Hormuz has become a focal point of global instability as tensions between the United States and Iran escalate into open conflict. This narrow waterway, which serves as the transit point for a significant portion of the world’s oil supply, is currently considered impassable for commercial shipping.
The primary causes for this closure involve a combination of kinetic military activity and severe maritime risks. Iranian forces have reportedly deployed naval mines throughout the channel while positioning anti-ship missile batteries along the coast to deter foreign intervention. These tactical choices create a high probability of vessel loss, leading global shipping firms and insurers to suspend all operations in the region.
In response to the blockade, the United States military has initiated a series of strategic maneuvers to restore freedom of navigation. The Pentagon recently authorized the deployment of additional carrier strike groups to the Persian Gulf to provide protective cover for clearing operations. U.S. Naval forces are working alongside international partners to identify and neutralize underwater mines, a process that requires precision and constant surveillance.
Beyond defensive measures, the United States has conducted targeted air strikes against military infrastructure that threatens transit lanes. These actions aim to degrade the offensive capabilities of the opposition and ensure that energy markets remain stable.
