Sanctions impacting a swathe of lines of business will keep requiring careful consideration in 2026. The past year has seen a rise in disputes related to sanctions regimes and the decisions of insureds – especially in the maritime sector. These decisions have not only related to the decisions of corporates that have breached sanctions, but also decisions made not to act pursuant to sanctions concerns (where this decision not to act has given rise to breach of contract). They have also highlighted the potential commercial liabilities of advisors (such as solicitors holding funds in escrow on behalf of parties that subsequently become subject to US sanctions) and the complexities of the (dis)application of the extraterritorial effect of certain sanctions regimes. These cases demonstrate that the English courts are increasingly subjecting the sanctions compliance decisions of businesses to high levels of scrutiny in order to assess whether they are objectively reasonable. Recent decisions indicate an increasing willingness by the courts to conclude that businesses are liable for damages in circumstances where cautious decisions are made to seek to comply with sanctions regimes of multiple jurisdictions and where the basis for those decisions might be undermined by other available evidence. Insurers need not only to be aware of the plethora of sanctions implications at play in international trade and business, but also to ensure that their decisions are thorough, well-documented and reasonable in deciding when to continue and when to hold back on the basis of sanctions breach concerns.
