When Banks Go Beyond Sanctions Requirements

A bank may refuse a relationship even where sanctions do not prohibit it. Understanding whether the decision rests on law, screening or commercial policy determines how it can be challenged.

The bank's message says it can no longer provide services. It offers little explanation. The customer is left to discover whether the problem is a legal prohibition, a name match, an unanswered compliance question or a commercial decision.

Those possibilities have different consequences. An argument that no sanctions rule prohibits the relationship may answer one of them and leave the others untouched. Effective representation begins by identifying what the bank has actually decided.

A legal restriction has a defined scope

Sanctions analysis requires the relevant programme, the persons involved and the transaction. Nationality, residence, ownership, control, payment routing and the services being supplied can all matter. A name absent from a public list does not by itself resolve every sanctions issue. Conversely, a connection with a higher risk country does not automatically prohibit every transaction.

A bank may also be subject to several legal systems or depend on a correspondent institution with its own obligations. A permission granted under one regime may have no effect under another. The analysis should identify each relevant restriction and any applicable authorisation before asserting that a payment must proceed.

That exercise can expose a screening error. Similar names, incomplete dates of birth and outdated company records can create false associations. The response should supply reliable identifiers and address the particular match. Repeatedly sending a general biography is unlikely to resolve a precise data problem.

Risk policy can extend further than the law

A bank can consider financial crime exposure, operational cost, correspondent relationships and commercial appetite when deciding whether to maintain a customer. Those considerations may lead it to decline activity that the law would permit. Whether the decision can be challenged depends on the contract, regulatory obligations and other applicable law.

The FCA's research into de-risking identified several drivers of banks' decisions, including profitability, reputational concerns and perceived financial crime risk. Its risk-based guidance also distinguishes management of individual risks from treating an entire customer category as uniformly unacceptable. These supervisory expectations need to be read alongside the rules governing the particular account.

Political exposure requires similar care. The 2020 joint statement by US banking agencies explains that PEP status does not automatically make every customer higher risk. The statement does not remove separate obligations for relevant private banking relationships. It does support the need to examine the customer's actual circumstances rather than rely on the label alone.

Make the review request answerable

A useful request sets out the customer identity, account history, ownership structure and transaction purpose in a coherent form. Supporting records should explain the source of funds and any discrepancy that prompted concern. Documents that contradict each other need an explanation before they reach the bank.

The request should seek the information the bank can lawfully provide and identify the remedy sought. That might be correction of a false match, reconsideration of a closure, access to a complaints process or clarification of the treatment of remaining funds. A demand for an unrestricted account is rarely a substitute for that precision.

There are lawful limits to what a bank can explain. In the UK regulated sector, tipping-off rules can restrict disclosures liable to prejudice an investigation. A limited explanation should therefore be examined carefully. It cannot safely be treated, without more, as proof of an unlawful motive.

Choose a remedy that fits the decision

An internal complaint, an eligible ombudsman referral, a data correction request and court proceedings perform different functions. Time limits, standing and the relief available need to be checked before selecting the route. Any urgent need for payroll, living expenses or other essential payments should be identified with evidence and addressed through lawful arrangements.

There is no sound universal promise that a bank must retain every customer whose activity is lawful. There is a strong case for requiring decisions to rest on accurate information and the legal standards that actually apply. The most effective challenge identifies the gap between those standards and the decision made.
