President Donald Trump announced that all naval mines have been removed from the Strait of Hormuz, warning Iran that any new mines placed in the waterway will be destroyed. The declaration, made on Truth Social, caps months of escalating military confrontation over the narrow passage that carries roughly one-fifth of the world’s oil supply.
Trump went further than just claiming victory over the mining threat. He designated the strait as “new US territory,” a phrase that carries more rhetorical weight than legal meaning but signals the administration’s posture toward maintaining control of the chokepoint.
A conflict months in the making
The standoff traces back to late February 2026, when Iran began deploying small craft to lay mines in the strait amid a broader military conflict involving the US, Israel, and Iran. The vessels used were modest in scale, capable of carrying just two to three mines each, but the cumulative effect on one of the world’s most critical shipping lanes was severe.
On March 10, Trump issued his first public demand that Iran immediately remove any naval mines from the Hormuz Strait. The alternative, he warned, would be “military consequences to Iran… at a level never seen before.”
Those consequences materialized quickly. US military forces destroyed between 10 and 16 Iranian minelaying vessels in the period following Trump’s warning. The Navy also deployed minesweepers to the region to begin clearing the waterway, a painstaking process given that US intelligence estimated Iran possessed approximately 6,000 naval mines before the conflict began.
The mines were laid by Iran’s Islamic Revolutionary Guard Corps navy, which has long trained for asymmetric warfare in the Persian Gulf.
The gap between claims and shipping data
By August 18-19, Trump declared on Truth Social that “The Hormuz Strait is open and operating.” Shipping analytics paint a considerably less optimistic picture. On a recent Monday, only around 10 vessels transited the strait. For context, the pre-war average was 130 to 140 vessels per day. That’s a decline of more than 90%.
Negotiations stalled
Diplomatic efforts to resolve the broader conflict have gone essentially nowhere. Trump denied that any talks with Iran were scheduled. Iran, for its part, has set preconditions that include the lifting of sanctions and the release of frozen assets before it would consider cooperating on restoring normal shipping operations.
What this means for energy markets
The broader energy supply chain faces cascading effects. Countries in Asia that depend heavily on Gulf oil imports are particularly exposed. Japan, South Korea, India, and China all receive significant portions of their crude through the strait, and prolonged disruption forces difficult choices about strategic reserves, alternative sourcing, and energy policy.
