Lloyd’s Cuts Cover for Hormuz ‘Transit Fees’: Can Ships Obey Iran Without Losing Their Insurance?
A new Lloyd’s Market Association clause says marine insurers will not cover payments made to pass through the Strait of Hormuz—and coverage may cease entirely if a payment is made. The rule leaves shipowners trapped between Iranian demands, sanctions law and physical danger.
The Lloyd’s Market Association has published a model clause that could transform Iran’s effort to charge or demand payments from ships passing through the Strait of Hormuz into an insurance crisis for the global maritime industry.
Under the new wording, marine hull insurers would not reimburse any transit fee, toll or other financial or non-financial payment made to enable a vessel to pass through Iranian territorial waters or otherwise transit the strait. More significantly, insurance cover for the vessel may cease once such a payment has been made because the transaction could create exposure under United States, United Kingdom or European Union sanctions and terrorism-financing laws.
The clause is voluntary model wording rather than a law automatically imposed on every policy. Its publication nevertheless sends a powerful market signal because Lloyd’s-linked underwriters play a central role in insuring international shipping.
The practical dilemma for shipowners is immediate.
Iran says it has the right to manage traffic through waters beside its territory and has attempted to impose routes, permissions or fees during the war. U.S.-supported maritime authorities reject that claim and say the Strait of Hormuz must remain open for international transit.
A ship approaching the strait may therefore face three conflicting pressures.
Iran may demand compliance or payment. U.S. or allied forces may instruct the vessel to use a different route. The insurer may warn that any payment could terminate cover.
The captain is not operating inside an academic legal debate. Refusing an Iranian demand could expose the tanker and crew to detention, missiles, drones or boarding. Paying could leave a vessel worth tens or hundreds of millions of dollars uninsured during passage through an active war zone.
The LMA says the clause provides contractual clarity and demonstrates due diligence. Insurers fear that reimbursing a payment to an Iranian authority, sanctioned entity or armed organization could violate sanctions or terrorism legislation. They also do not want insurance policies to become an indirect mechanism for financing a coercive toll system.
From a compliance perspective, the logic is understandable. If insurers routinely covered payments demanded under military threat, the cost would be transferred to the insurance market and ultimately to consumers. That could normalize extortion and reduce incentives for governments to protect free passage.
Shipowners may see the situation differently. They could argue that a payment made under immediate threat is not voluntary support for Iran or terrorism. It is a ransom-like decision intended to protect civilian seafarers, cargo and the environment.
The clause reportedly applies not only to cash but also to other forms of consideration. That raises difficult questions. Would providing information, changing destination, carrying a particular pilot or accepting an Iranian escort count as a non-financial payment? The detailed guidance and individual policy wording will matter.
The rule could also change shipping behavior before any payment occurs. Owners may avoid Hormuz entirely if they cannot be certain that cover will remain valid. Charterers may refuse contracts involving Gulf ports. Banks financing vessels may demand additional guarantees. Crews may decline assignments.
In that sense, the insurance response can deepen a partial blockade even without another ship being attacked.
Iran may accuse Lloyd’s and Western regulators of participating in the U.S. economic campaign. Tehran could argue that the clause denies shipowners the flexibility to comply with legitimate coastal-state requirements and uses private insurance to enforce Western sanctions.
The opposing view is that Iran is attempting to monetize military control of an international waterway. Allowing insured payments would reward that strategy and encourage similar demands in other chokepoints.
The legal status of the strait remains central. The Strait of Hormuz is used for international navigation and is bordered by Iran and Oman. International law generally protects transit passage, although Iran and the United States disagree over the application of relevant treaty provisions and the authority of warships and commercial vessels.
War complicates the situation further. The United States is enforcing a blockade against Iranian ports while arguing for free passage through Hormuz. Iran says it is responding to attacks and restrictions on its own commerce.
A shipping company may reasonably ask why it should bear the legal and physical consequences of a geopolitical confrontation it did not create.
There is also an environmental dimension. A tanker disabled, detained or attacked in narrow waters could release large quantities of oil. Insurance exclusions may protect underwriters from sanctions risk while reducing the financial mechanisms available for response, salvage and compensation.
Governments may eventually need to provide sovereign guarantees or special insurance pools, as they have done in other conflicts. Naval escorts alone may not solve the commercial problem if a vessel’s policy can disappear because of an interaction with Iranian authorities.
The Lloyd’s clause is therefore more than technical contract language. It reveals how war moves through invisible systems of finance, law and risk assessment.
Iran may be able to demand a fee. The United States may be able to escort a ship. But the insurer decides whether the vessel remains economically capable of sailing afterward.
The open question is whether the new clause protects international law—or leaves civilian captains with no legally safe choice when armed authorities demand compliance in the world’s most important oil chokepoint.
