Lloyd's Market Voids Hull Cover for Ships That Pay Iran's Hormuz Toll — Payment Itself Now the Sanctions Trigger
London, 23 July 2026
Key points
- The Lloyd's Market Association published a new model clause and guidance note on 23 July for marine hull insurers, addressing transit-fee payments demanded by Iran for passage of the Strait of Hormuz
- Under the clause, insurers provide no cover for the payment itself and, in the LMA's words, "cover for the relevant vessel will cease due to the risk of a breach of sanctions and/or terrorism legislation in the US, UK or EU" — the exclusion reaching "financial or other forms of payment"
- Arabella Ramage, the LMA's legal and regulatory director, said the clause and guidance "align with existing sanctions and terrorism frameworks, while also evidencing the insurer's due diligence"
- Because of the Lloyd's market's weight, its model clauses set contract standards worldwide; traffic through the strait has already thinned, with shipbroker Arrow counting an average of four outbound and three inbound tanker transits a day, down from eight and seven earlier in the ceasefire period
The Lloyd's Market Association issued a model clause on 23 July under which a shipowner who pays Iran's Strait of Hormuz transit toll loses hull cover for the vessel — making the payment itself the trigger for a lapse in insurance, on the ground that it risks breaching US, UK or EU sanctions and counter-terrorism law.
Iran has charged for passage of the strait since late March, with first official toll revenues reported by mid-April; according to Handelsblatt's account, it has attacked ships that refused to pay. Parliament speaker and chief negotiator Mohammad Bagher Ghalibaf has said the strait "will not return to its pre-war state" and that Iran will exercise its sovereign rights and charge "for its services." The LMA clause answers the resulting question for underwriters: a toll paid to a sanctioned authority is a compliance exposure, and the model wording resolves it by voiding cover for any vessel that pays.
The clause is guidance, not law, but the Lloyd's market's scale gives its model wordings the force of a standard — hull policies written far outside London routinely incorporate LMA clauses. Its effect is to remove the middle option a shipowner might have hoped for: buying passage and keeping cover at once.
Enforcement of the strait's status has migrated from navies to underwriters. The same commercial mechanism that sealed the corridor in the war's opening weeks — the withdrawal of war-risk cover — now polices whether anyone may buy their way through it, leaving owners a closed pair of options: pay and sail uninsured, or refuse and accept the risk. As Großwald Signal No. 108 observed, it is a Western-services gate of the kind the EU's frozen Russian oil cap also relies on — insurance and shipping, not warships, doing the enforcing in two theatres at once. The observable to watch is Arrow's transit count, already halved within the ceasefire period, which the clause gives every hull underwriter a reason to push lower.
