Iran’s Islamic Revolutionary Guard Corps (IRGC) deputy naval commander, Mohammad Akbarzadeh, has declared the Strait of Hormuz “completely under the control” of Iranian forces and said more than a dozen oil tankers transiting the waterway were struck by artillery fire and burned. He told state-linked Fars news agency that the IRGC had repeatedly warned that the strait was in a state of war and that any vessel could be hit by shelling or unmanned aerial systems, and that after Iran’s announcement banning passage, tankers, merchantmen and fishing boats can no longer transit.
The claims—carried in Chinese state media outlets citing Fars—cannot be independently verified and echo a pattern of maritime coercion that has punctuated the Gulf for years, including tanker seizures and episodic attacks in previous periods of heightened tension. Regardless of verification, the IRGC’s statement is notable for its blunt assertion of control over one of the world’s most consequential maritime chokepoints and for the implied willingness to use lethal force against civilian shipping.
The Strait of Hormuz is the principal exit for crude and refined products from the Persian Gulf; historically roughly one-fifth of global seaborne oil passed through it. Any sustained disruption would quickly reverberate through global energy markets, push up freight and insurance costs, and force shippers to consider expensive detours around Africa. Governments that rely on Gulf energy—Europe, East Asia and others—would face both immediate market volatility and strategic decisions about naval protection and diplomatic pressure.
Strategically, Iran’s message serves multiple purposes: it signals deterrence to potential adversaries, attempts to coerce political concessions by raising the cost of sanctions and military pressure, and tests the unity and appetite for confrontation among Western and regional navies. The risk now is miscalculation. International actors face a stark choice between placating Iranian coercion to keep shipping open and responding forcefully to restore freedom of navigation, a response that could rapidly escalate into wider military confrontation with unpredictable consequences for regional security and the global economy.
