Iran announced it has collected its first payment from a commercial vessel transiting the Strait of Hormuz. If confirmed, it is a move without modern precedent and one that is already drawing a sharp response from Washington.
Tehran says the fee has been deposited into Iran’s central bank, framing the charge as compensation for damage caused by recent US and Israeli military actions in the region. The exact figure has not been officially disclosed, but shipping industry sources estimate that large tankers could face charges of up to one million dollars per transit. Iranian authorities say the Islamic Revolutionary Guard Corps is carrying out enforcement in the waterway, though independent verification of reported vessel detentions and diversions remains limited.
President Donald Trump responded by calling the toll system a direct violation of international maritime law. Washington’s position is longstanding and unchanged: the Strait of Hormuz is an international waterway, and the right of transit passage is guaranteed to all vessels under international law, irrespective of conditions on shore. US Central Command has expanded its naval deployments in surrounding waters, including the Gulf of Oman.
Shipping through the Strait of Hormuz , the narrow passage carrying roughly a fifth of the world’s daily oil supply , has slowed dramatically. Vessel movements have fallen sharply. Insurance premiums have surged to the point where many transits are no longer commercially viable. Operators now face a stark choice: absorb the costs, reroute through longer and more expensive alternatives, or stop moving altogether.
Some are finding workarounds. A number of tankers have switched off their tracking systems, effectively going dark. Others are transferring cargo at sea, outside the Strait, trying to avoid both Iranian enforcement and US interception.
At the heart of the standoff is a legal dispute. Iran says it has the right to impose transit fees under active conflict conditions. Washington and its allies say international law is clear: passage through an international strait must remain free, and no unilateral declaration changes that.
With Iranian patrol vessels operating in the enforcement zone and US naval assets repositioned nearby, A single miscalculation, one boarding attempt met with force, could collapse what remains of the diplomatic track within hours.
