A UK-clearing bank notifies a regional correspondent that it will terminate the relationship in sixty days. No enforcement action is pending. No designation has been issued. The reason given is "sanctions risk" – a category wide enough to cover almost anything and narrow enough to feel final. For the correspondent, and for the trade-finance clients that depend on it, the question is immediate: what does OFSI actually require, what leeway does the clearing bank have, and is there a route back?
Correspondent-banking de-risking (a financial institution exiting or restricting a relationship to reduce sanctions exposure) sits at the intersection of OFSI's financial-sanctions enforcement mandate and the commercial risk appetite of the UK's clearing banks. As of January 2026, OFSI does not require banks to exit any specific correspondent relationship; the decision to de-risk is a commercial one, not a statutory command. The gap between what OFSI prohibits and what banks voluntarily avoid creates the practical problem.
This guide works through the legal basis for UK financial sanctions, how OFSI's ownership-and-control test operates, where correspondent banks make mistakes, and when specialist counsel should be engaged.
Step 1: Understand the legal basis before diagnosing the risk
The first step is to distinguish what UK financial-sanctions law actually prohibits from what banks apply as a precautionary overlay. OFSI administers financial sanctions under the Sanctions and Anti-Money Laundering Act – "SAMLA" – and the relevant thematic regulations made under it. The prohibitions bite on dealing with funds or economic resources of a designated person, or on making funds available to such a person. The operative question is always: does the counterparty fall within the prohibition?
Banks often apply de-risking policies that go far beyond what the prohibition strictly demands. A correspondent may be exited not because it is designated, or because a designated person owns or controls it, but because the correspondent operates in a jurisdiction that the clearing bank treats as high-risk. OFSI's published guidance draws a clear line between what is legally required and what is commercially chosen. Understanding that line is the foundation of any challenge to a de-risking decision.
The applicable legal structure runs through SAMLA at the primary level and, for each active sanctions programme, through the relevant thematic regulations – for example, the regulations relating to the programmes that OFSI currently administers across more than a dozen active thematic and country-based regimes. None of those instruments contains a provision that requires a bank to exit a correspondent relationship on the basis of jurisdiction alone.
In our experience, the first task when a correspondent receives a termination notice is to identify precisely which legal concern the clearing bank has articulated. Is it a designation hit? An ownership-and-control concern under the beneficial-ownership rules? Or is it a risk-appetite decision dressed in regulatory language? The answer determines the available options.
Step 2: Apply the OFSI ownership-and-control test to the correspondent chain
Under OFSI's guidance, a non-designated entity is caught by UK financial-sanctions prohibitions where a designated person owns or controls it – a test that covers both the mechanical ownership threshold and a broader control analysis. This is where the UK and EU positions diverge from the US approach under OFAC.
OFAC applies the 50 percent rule (treating any entity owned 50 percent or more in the aggregate by designated persons as itself blocked). The test is arithmetic. OFSI and the EU Council apply an ownership and control test (the UK and EU standard for whether a non-listed entity is caught through a listed person). Control can be established through shareholding, through rights over governance, or through other means by which a designated person can direct or unduly influence the entity. A correspondent that passes the 50 percent threshold screen under an OFAC-style tool may still require a fuller control analysis under the UK rules.
The practical implication is significant. A correspondent bank operating in a market where several designated persons are prominent investors across many sectors may need to demonstrate – not merely assert – that no designated person controls the entity through indirect means. We regularly advise correspondents on how to structure that ownership-chain analysis to satisfy the evidentiary standard that OFSI and the clearing bank will each apply.
Three points in the control analysis where mistakes are most frequent:
- Golden shares and governance rights that sit outside the formal shareholding structure but allow a designated person to block board decisions
- Nominee arrangements that obscure beneficial ownership at the second or third tier of the chain
- Contractual arrangements – loan agreements, offtake contracts – that give a designated person rights over the commercial direction of the entity
Each of these can establish control in the UK and EU sense even where no shareholder holds a blocking stake. Have you traced the beneficial-ownership and governance structure all the way to natural persons, or only to the first corporate layer?
Step 3: Map the reporting and record-keeping obligations
Before engaging with the clearing bank on a de-risking decision, a correspondent should ensure its own reporting house is in order. OFSI's regime includes mandatory reporting obligations that attach to financial institutions. A firm that is aware of a transaction or account involving a designated person – or an entity owned or controlled by one – is required to report to OFSI.
The obligation to report is not conditional on a prohibition having been breached. The trigger is knowledge or reasonable cause to suspect that a person is a designated person or is otherwise subject to the financial-sanctions prohibitions. Record-keeping obligations run alongside the reporting duty: relevant records should be maintained for a period sufficient to support any regulatory enquiry. The applicable period under UK anti-financial-crime rules is well-established, and sanctions-specific record-keeping expectations align with that standard – five years is the benchmark across the UK financial-crime regime, verify the current position before relying on it in a specific OFSI context.
A correspondent that presents itself to a clearing bank as well-governed will have documentary evidence of its own screening, its own ownership-chain analysis, and its reporting decisions. That documentation is also the foundation of any licence application to OFSI, should the clearing bank require a formal authorisation before reinstating access.
The cross-regime dimension matters here. If the correspondent also maintains relationships with US-correspondent banks, OFAC's reporting and blocking requirements may run in parallel. The two regimes do not operate identically; a VSD (voluntary self-disclosure to a regulator) to OFSI does not substitute for any obligation under the US system, and vice versa. Coordination between UK and US counsel is necessary where both regimes are live.
Step 4: Assess the licensing route before accepting exit as final
A specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) is available from OFSI where the transaction would otherwise breach a UK financial-sanctions prohibition. Where the clearing bank's concern is that a specific payment or category of service falls too close to a designated person, a specific licence from OFSI can provide the legal certainty that the bank requires to proceed.
The licensing route is frequently overlooked. In our practice, we see correspondents accept exit as a fait accompli when a targeted application to OFSI – covering the specific transaction type, the identified counterparty chain, and the compliance controls already in place – would have satisfied the clearing bank's risk-management requirements. OFSI publishes licensing grounds across its active programmes; the applicable ground must be identified and the application structured to address it.
The position above covers the standard case. Your facts – the counterparty, the goods or services involved, the designated-person connection, the specific programme in play – change the analysis considerably. A clearing bank's de-risking decision may reflect a concern about a specific transaction category rather than the relationship as a whole, and a well-framed licence application can address that concern precisely.

Step 5: Identify the cross-regime risk profile before responding to the clearing bank
A correspondent that responds to a UK clearing bank's de-risking notice without first mapping its full cross-regime exposure risks narrowing its options unnecessarily. The UK regime is one layer. OFAC's extraterritorial reach is a second. EU Council regulations are a third. Where the clearing bank operates a US dollar-clearing function, its own OFAC exposure may be driving the UK de-risking decision even when the notice is framed in OFSI terms.
This is a structural feature of major currency clearing. US dollar payments routed through a US correspondent bank – or processed by a US branch of a non-US bank – are subject to OFAC jurisdiction regardless of where the parties to the underlying transaction are located. A UK clearing bank with a substantial US dollar business may apply OFAC's standards as a floor, which in practice sets the threshold for the entire correspondent relationship, not just the US-currency transactions.
The EU dimension arises for correspondents that also maintain euro-clearing relationships. EU Council regulations apply to EU-credit institutions and to non-EU entities conducting transactions in euros that pass through EU-clearing infrastructure. A correspondent whose business spans sterling, US dollar, and euro payments may be subject to OFSI, OFAC, and EU rules simultaneously, and the strictest prohibition among them governs the practical position.
Switzerland's SECO, Canada's Global Affairs Canada, and Australia's DFAT each maintain sanctions regimes that may be relevant depending on the correspondent's transaction flows and domicile. In our cross-border practice, we map the full regime profile before advising on the response strategy, because a solution that addresses the OFSI concern but leaves an OFAC or EU question unresolved will not restore the relationship on a durable basis.
If a transaction has already been flagged, or a clearing bank notice has been received, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com for a confidential assessment.
Step 6: Recognise the common risk flags in correspondent-banking de-risking decisions
Not every de-risking decision reflects a genuine sanctions exposure. Some reflect miscalibrated screening tools. Others reflect geographic over-inclusion – the clearing bank applying a blanket restriction to all correspondents in a given market without a transaction-level analysis. Understanding which risk flag drove the decision shapes the response.
The following patterns appear most frequently in the matters we handle:
- False-positive screening hits: a name in the correspondent's ownership chain that resembles a designated person's name but is a different individual. These can usually be resolved with documentary evidence – corporate registry records, identification documents, and a clear explanatory note to the clearing bank.
- Aggregate-ownership errors: the clearing bank's model flags an entity because a designated person holds a minority stake, without applying the aggregation analysis that OFSI and OFAC both require before treating the entity as caught.
- Jurisdictional over-reach: a clearing bank exits all correspondents in a market on the basis of one high-profile enforcement action against a different institution in that market, without assessing whether the individual correspondent's transaction flows create the same exposure.
- Control-test gaps: a screening tool that applies only the mechanical 50 percent test and does not pick up governance-level control arrangements of the kind that OFSI's ownership-and-control standard captures.
- Stale customer due-diligence data: ownership structures change. A correspondent whose clearing bank holds a three-year-old due-diligence file may find the bank unwilling to extend a grace period because it cannot form a current view of the risk.
The myth that de-risking is always a regulatory inevitability deserves direct attention. Banks have commercial and reputational reasons to serve well-governed correspondents. A correspondent that can demonstrate a current, documented, and properly tested ownership-and-control analysis – and that can explain its transaction flows clearly – is in a materially better position than one that responds defensively. The regulator is not the obstacle; the clearing bank's risk function is, and it can be engaged.
Step 7: Structure the engagement with the clearing bank and OFSI
The final step is to sequence the engagement correctly. Approaching the clearing bank before completing the internal analysis is the most common error we see. A premature submission that raises more questions than it answers can accelerate rather than prevent exit.
The recommended sequence is:
- Complete the ownership-and-control analysis to a documented standard, covering all tiers to natural persons.
- Identify any designated-person connection – however indirect – and assess whether it triggers the prohibition or falls below the ownership and control threshold under OFSI's published guidance.
- Assess whether a specific licence from OFSI is required or would provide useful certainty for the clearing bank.
- Prepare a structured response package: the ownership-chain analysis, the screening methodology, the transaction-flow summary, and – where applicable – the licence application or OFSI correspondence.
- Engage the clearing bank's risk or compliance function directly, with the package as the basis for discussion, not the starting point of a negotiation conducted without supporting material.
- Where the de-risking decision has already taken effect, assess whether OFSI's formal mechanisms – including engagement with OFSI on the licensing position – provide a route to documented clearance that the next clearing bank will accept.
Timeline is always a pressure. Clearing banks typically give notice periods that are commercially workable but leave little space for a full ownership-chain analysis, a licence application to OFSI, and the documentation of a revised due-diligence file. Starting early is not a counsel of perfection; it is a functional requirement.
What does that mean in practice? In a recent matter, a mid-sized trade-finance correspondent received exit notice from its primary UK clearing bank, citing concerns about a minority investor in one of the correspondent's regional subsidiaries. We mapped the full ownership and governance structure across five tiers, identified that the investor held a position below both the OFSI ownership threshold and the OFAC 50 percent standard, prepared a documented analysis for the clearing bank, and engaged OFSI on the correspondent's general compliance posture. The relationship was restored within the notice period. No licence application was ultimately required, but having the analysis prepared to licence-application standard was what gave the clearing bank the confidence to re-engage.
