A regional bank in South-East Asia notifies its European correspondent that it will terminate the relationship within ninety days. The notice cites "evolving risk appetite" but offers no further detail. The European bank's compliance team suspects the trigger is a cluster of transactions routed through jurisdictions subject to the applicable country regimes. The question is immediate: is the termination legally defensible under each regime that touches the relationship, and what steps must both institutions take before the line goes dark?
Correspondent-banking de-risking (the exit by a correspondent bank from a respondent relationship to reduce sanctions and financial-crime exposure) sits at the intersection of at least three major regimes simultaneously. OFAC, OFSI, and the EU Council regulations each impose distinct obligations on the correspondent, the respondent, and – in certain circumstances – the end customer. As of January 2026, no single international standard harmonises how institutions document, sequence, and report a de-risking exit.
This guide works through the procedure step by step, maps where the major regimes diverge, and identifies the risk flags that most frequently cause exits to generate – rather than eliminate – regulatory exposure.
Step 1: Identify the governing regimes before you act
The first task is to map every jurisdiction whose sanctions rules can touch the relationship before a single exit notice is drafted. A correspondent-banking relationship rarely sits inside one regime. The correspondent's home jurisdiction, the respondent's home jurisdiction, the currency of settlement, the clearing infrastructure used, and the ultimate beneficiaries of the transactions each carry their own legal colour.
OFAC's reach is the broadest starting point. Any transaction cleared in US dollars passes through a US correspondent account, bringing the relationship within OFAC's jurisdiction regardless of where the parties are incorporated. This extraterritorial reach means that a Swiss bank, a Singapore bank, and a Japanese bank operating a USD-clearing relationship are each subject to OFAC rules as a threshold matter. OFSI and the EU regulations apply by incorporation, residence, and – for EU rules – by the conduct of business within the EU's territory. Where a respondent has EU-incorporated entities or operates euro-clearing lines, EU Council regulations are live.
In our cross-border practice, the most common error at this stage is scoping only the correspondent's home jurisdiction. The respondent's licence position, the regimes applicable to the end-beneficiary jurisdictions, and any secondary-sanctions exposure all require separate mapping. That mapping is the foundation of every subsequent step.
The applicable country regimes for Singapore, Japan, and the UAE each operate on a domestic basis but interact with OFAC and EU rules through correspondent relationships and dollar clearing. A Singapore-incorporated respondent whose transactions route through a US correspondent brings OFAC into the analysis even if the Singapore Monetary Authority's rules impose no independent sanction on the same counterparty.
Step 2: Conduct a structured pre-exit sanctions and due-diligence review
Before issuing a termination notice, the correspondent should complete a structured review that treats sanctions exposure and the de-risking decision as distinct but related questions. Conflating them – exiting because a counterparty is difficult to screen rather than because it is sanctioned – is itself a regulatory risk under certain regimes.
The review has four elements. First, screen the respondent institution, its ownership chain, and its senior management against the SDN List (OFAC's list of Specially Designated Nationals and blocked persons), the UN Consolidated List, the EU consolidated list, and the OFSI consolidated list. Apply the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) to the ownership structure of the respondent. Under OFSI and the EU, apply the ownership and control test (the UK and EU test for whether a non-listed entity is caught through a listed person), which extends to control through non-ownership means.
Second, review the transaction history for patterns consistent with prohibited transactions under the applicable country regimes. This is not a compliance audit of the respondent; it is the correspondent's own assessment of its exposure to past and continuing violations.
Third, assess whether any live transactions are in progress that would constitute a block or freeze obligation if the relationship is terminated mid-transaction. OFAC requires that blocked property be held and reported; exiting without addressing a mid-flight blocked transaction does not discharge that obligation.
Fourth, consider whether the respondent holds assets or positions that would need to be unwound in a manner consistent with each regime's requirements. The position under EU law may differ from the OFAC position, particularly where the respondent has EU-linked assets.
Step 3: Map the reporting and disclosure obligations regime by regime
Reporting obligations attach to sanctions hits, blocked transactions, and – in some regimes – to the act of terminating a relationship itself. These obligations differ substantially across the major regimes, and a correspondent managing a multi-regime exit must track all of them simultaneously.
Under OFAC, a US financial institution that blocks property must report the blocking to OFAC within 10 business days. Annual reports of blocked property are also required. The same institution must file a report when a transaction is rejected – that is, when the transaction is not blocked but is nonetheless refused. These are distinct filings with distinct deadlines. Failing to file while also exiting the relationship compounds the violation.
OFSI's reporting obligations apply when a UK-regulated institution knows or has reasonable cause to suspect that a person it is dealing with is a designated person, or holds frozen assets. The reporting window is short – verify the current position before relying on it – and failure to report is itself an offence under the Sanctions and Anti-Money Laundering Act ("SAMLA"). OFSI also expects institutions to report the existence of frozen funds; terminating a correspondent relationship does not discharge the freeze obligation on assets already held.
EU reporting obligations under the relevant Council regulations require institutions to notify the competent national authority of assets frozen or withheld. In a multi-jurisdiction exit, this means parallel filings to OFSI, to the relevant EU member-state authority, and to OFAC – each on its own timetable and in its own form. We regularly advise institutions that the parallelism of these obligations generates its own operational risk: a filing made correctly under one regime may be timed in a way that inadvertently signals a sanctioned counterparty before the freeze is secured under another.
The position under the applicable country regimes for Singapore and Japan is broadly domestic: each has its own competent authority and its own reporting window. Where a respondent is Singapore-incorporated but the relationship clears in US dollars, both MAS-applicable rules and OFAC rules may require concurrent action.
The position above covers the standard case. Your facts – the counterparty, the currency of settlement, the jurisdiction of incorporation, the assets in play – change the analysis significantly.

Step 4: Structure the exit notice to avoid creating new liability
The exit notice is a legal document. Under each major regime, its content, timing, and method of delivery can affect whether the correspondent has complied with or breached its obligations. Drafting it without regard to the sanctions position is a consistent source of enforcement risk.
Under OFAC's framework, a financial institution that terminates a correspondent relationship must not, in doing so, tip off a designated person that assets are about to be blocked. The tipping-off concern is separate from and additional to the blocked-property reporting obligation. If the respondent itself, or a known beneficial owner, is designated, the exit notice should be reviewed by counsel before delivery.
OFSI and the EU regulations impose similar constraints. Tipping off a designated person that an asset freeze is imminent is itself prohibited conduct under SAMLA and the relevant Council regulations. Where the de-risking decision is triggered by a designation that has not yet been made public – or where the institution suspects a forthcoming designation – the drafting window is particularly narrow.
A further structural point concerns the notice period. Commercial agreements governing correspondent relationships typically require ninety days' notice. If, during that ninety-day period, a transaction is processed that later proves to involve a blocked party, the correspondent has extended rather than closed its exposure. In our experience, compliance teams that negotiate the commercial exit without simultaneously reviewing the ongoing transaction-monitoring obligations for the notice period regularly find that the notice period is the most exposed phase of the exit.
If a transaction has already been flagged, or a correspondent relationship has been placed under enhanced scrutiny by a regulator, an early confidential review can preserve options that narrow with time. Contact us at info@caldervance.com.
Step 5: Address the documentation and record-keeping requirements
Documentation is the correspondent's primary defence in an enforcement proceeding. Each of the major regimes imposes a record-keeping obligation, and the periods differ. Institutions should retain documentation for the longer of the applicable periods where regimes overlap.
OFAC's guidance indicates that records relating to blocked transactions should be retained for five years from the date of the transaction, or for the duration of the blocking, whichever is longer. For institutions subject to both OFAC and OFSI rules, OFSI's record-keeping requirements under SAMLA and the relevant thematic regulations should be verified independently and applied to the same document set. The EU requirements, set out in the relevant Council regulations, similarly impose a retention obligation that practitioners should verify as currently in force before relying on it.
The documentation package for a correspondent-banking exit should include, at minimum: the sanctions-screening results for the respondent and its ownership chain; the transaction-history analysis; any correspondence with the regulator or the respondent concerning the relationship; the formal exit notice and proof of delivery; records of any blocked or rejected transactions during the notice period; and the filings made to each competent authority.
A common gap we see in post-exit reviews is the absence of documentation showing why the de-risking decision was taken. An institution that cannot demonstrate that its exit was a compliance response to a genuine sanctions risk – and not simply a discriminatory commercial decision against a category of respondent – faces a different category of risk in jurisdictions where financial-inclusion obligations attach to correspondent relationships. This is a growing area of regulatory attention in several markets, and it reinforces the value of a documented, structured exit process.
Step 6: Manage the cross-regime interaction and secondary-sanctions exposure
The final step – and the one most frequently underweighted – is assessing the secondary-sanctions dimension of the exit itself. A correspondent bank that is not itself a US person but that clears in US dollars, or that has US-person directors or shareholders, may be exposed to secondary sanctions (US measures that restrict non-US persons from dealing with certain parties or in certain sectors) if the respondent's counterparties include parties subject to an applicable country regime carrying secondary-sanctions implications.
Secondary-sanctions exposure does not require a direct relationship with a blocked party. It can arise from transactions that touch a sector, a jurisdiction, or a counterparty type covered by a programme's secondary-sanctions provisions. In our cross-border practice, the assessment of secondary-sanctions risk runs in parallel with – not after – the primary-sanctions screening. Sequencing the two as if they were separate exercises generates gaps.
The divergence between OFAC and the EU Blocking Regulation is a live operational tension in correspondent-banking exits. The EU Blocking Regulation prohibits EU persons from complying with certain extraterritorial US measures. An EU-incorporated correspondent that exits a relationship solely to comply with OFAC secondary-sanctions risk may find itself in technical breach of the Blocking Regulation's prohibition on compliance. The interaction is not a theoretical concern; it is a regular feature of de-risking advisory work involving EU-regulated institutions with US-dollar clearing lines.
Equally, a non-EU correspondent that continues a relationship to avoid Blocking Regulation exposure may be extending its OFAC risk. There is no universal resolution to this tension; the analysis turns on the institution's incorporation, its US nexus, its EU nexus, and the specific secondary-sanctions programme in play. The stricter prohibition governs where both apply to the same conduct – but identifying which prohibition is stricter requires a precise regime-by-regime comparison, not a general principle.
Common mistakes and risk flags in correspondent-banking de-risking
Six patterns account for the majority of compliance failures in correspondent-banking exits. Each is identifiable before the exit if the pre-exit review is structured correctly.
- Screening the respondent institution only, not its ownership chain. The 50 percent rule and the ownership-and-control test both operate through layers of ownership. A clean name search on the correspondent account holder is not a sanctions screen.
- Treating the exit notice as a commercial document. The notice period is a live sanctions-compliance period. Transaction monitoring obligations continue; blocked-property obligations arise during it; tipping-off prohibitions constrain its content.
- Filing with one regulator and assuming parallel obligations are discharged. OFAC, OFSI, and EU national competent authorities each require independent filings. A submission to OFAC does not inform OFSI.
- Failing to assess the secondary-sanctions dimension. Secondary-sanctions risk arises from sector exposure and jurisdictional patterns, not only from named-party matches.
- Underestimating the Blocking Regulation tension. EU-incorporated correspondents with US-dollar clearing lines face a structural conflict in some de-risking scenarios. The conflict must be identified and managed; it cannot be ignored.
- Inadequate documentation of the decision basis. An exit that is not documented as a compliance response to a genuine sanctions risk is vulnerable to challenge under financial-inclusion obligations in some jurisdictions, and provides no mitigation credit in a sanctions enforcement context.
A widespread myth in this area is that correspondent-banking de-risking is primarily a commercial decision that compliance teams merely ratify. That framing is incorrect. Each major regime treats de-risking as a regulated activity with its own obligations, and the decision to exit is as legally significant as the decision to continue. Compliance counsel should be engaged before the commercial decision is finalised, not after the notice is issued.
