Iran Pauses Strait of Hormuz Fees: What's at Stake in 60 Days

Iran's maritime authority announced on June 19, 2026 that it would temporarily waive new transit fees through the Strait of Hormuz for 60 days while negotiations take place, according to Reuters. The move suspends — but does not withdraw — a fee structure that Washington has already challenged.

The distinction matters. Iran is not backing away from its claim that it can charge vessels to pass through the strait. It is simply delaying enforcement. This sends a signal to every tanker operator and energy importer: Tehran views this waterway as something it can monetize. The Strait of Hormuz carries roughly 20 percent of the world's seaborne oil, making it by far the most important chokepoint in global energy logistics.

The Legal Question

When asked about the fees, maritime law experts told the New York Times in June that there is a sharp legal divide. Port fees and charges for piloting services are allowed under international law in certain cases. A unilateral toll on simply passing through an international strait is not.

The governing rule is the UN Convention on the Law of the Sea, or UNCLOS — a treaty that defines what rights and responsibilities countries have over ocean waters. Under Article 44 of UNCLOS, countries that border a strait used for global shipping cannot place tolls on the passage itself, or do anything else that would block or impede that passage. A transit toll directly violates that principle.

Iran's position relies on a technicality: Iran has not signed UNCLOS, so it argues the treaty does not bind Tehran. This argument has not gained traction internationally. The United States, European Union, and Gulf nations — all dependent on reliable passage for their own trade and energy exports — would certainly challenge it.

What Washington Says

Secretary of State Marco Rubio stated in May that Iran has no authority over the Strait of Hormuz and cannot restrict shipping through it, according to the State Department. He specifically mentioned mines as a concern, signaling that U.S. officials are considering what might happen if tensions escalate beyond fee collection.

The broader context here is that the 60-day waiver may not be primarily about collecting tolls. Iran could be using the fee threat as leverage in wider negotiations over nuclear agreements or international sanctions. The fact that Iran chose to pause rather than enforce the fees suggests officials in Tehran are aware of how much international pushback any toll would face.

What remains unclear is what those larger negotiations might cover, and whether they can reach an agreement before the two-month window closes.

The Shipping and Energy Impact

For now, the calculus is simple: vessels pay nothing and can pass freely. But the medium term is less certain. Insurance companies and shipping firms will watch these negotiations closely. If no deal emerges by the time the waiver expires, Iran will face a hard choice — back down or start collecting fees. The second option would almost certainly trigger legal challenges and possibly a military response from multiple countries.

The problem is that there is no easy way to reroute the traffic that uses this strait. Saudi Arabia operates a pipeline that bypasses Hormuz, and the UAE has another. But neither can handle the full volume of oil that normally flows through the strait. That means if Hormuz passage becomes costly or dangerous, global energy prices could spike, and there is no simple alternative.

The deeper issue will not be settled in 60 days. By announcing these fees — whether enforced or not — Iran has made a formal claim about who controls the Strait of Hormuz. That claim contradicts what international maritime law says. Whether Iran backs down, negotiates a middle ground, or presses forward, the question of who really governs this waterway will remain a point of tension in global shipping for years to come.
