Short answer
Sanctions risk is the risk that a company breaches sanctions or loses business because a counterparty, vessel, product or payment route is linked to a sanctioned country or party. In 2026 the biggest exposures are Iran, Russia and Venezuela, with the US expanding shadow fleet designations and warning foreign banks of secondary sanctions.

How sanctions risk reaches you
Through customers, suppliers and agents with hidden ownership links; vessels with sanctioned histories; banks that refuse or freeze payments; and goods that contain restricted components or origins.
What changed in 2026
The US Treasury designated 17 more tankers and 13 shipping companies linked to Iranian oil in October 2026 and warned foreign banks they could face secondary sanctions for significant Iran related transactions. Iran's conditions for reopening Hormuz include lifting new US sanctions, so the regime could change quickly in either direction.
How to manage it
Screen ownership to the ultimate beneficial owner, screen vessels by history and not only by name, include sanctions clauses that allow exit, and watch for diplomatic changes that could lift or tighten measures.
What happens next?
We assess it is almost certain that new US Iran related designations are announced before year end.
We assess it is unlikely that significant US sanctions on Iran are lifted by Dec 31.
