A UK-based trading company has just discovered that a key contractual counterparty was designated under a UK financial sanctions regime two weeks ago. Outstanding invoices sit unpaid. Goods in transit are caught mid-journey. A long-standing supply agreement has months left to run. Every day of inaction deepens the legal exposure – and every action without authorisation may itself constitute a sanctions breach.
A wind-down authorisation (a specific licence issued by the Office of Financial Sanctions Implementation permitting a sanctioned party or a business dealing with one to complete, reduce, or exit an existing contractual position in an orderly way) is frequently the only lawful route out of this position. As of June 2026, OFSI administers wind-down authorisations under the Sanctions and Anti-Money Laundering Act 2018 ("SAMLA") and the relevant thematic regulations. The authorisation does not permit new commercial activity; it permits measured exit from activity that predated the designation.
This guide walks through the governing authority, the eligibility test, the application procedure, the cross-border complications that arise when OFAC and EU counterpart regimes are also in play, the most common filing errors, and when to engage specialist sanctions counsel.
What is OFSI and what authority does it hold over wind-down authorisations?
OFSI – the Office of Financial Sanctions Implementation, a unit of HM Treasury – is the competent UK authority for administering, enforcing, and licensing financial sanctions obligations arising under SAMLA and the thematic regulations made under it. Its licensing function is the statutory gateway through which a person or business may obtain a specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) or, in limited circumstances, rely on a general licence (a standing authorisation for a defined category of activity).
Wind-down authorisations fall within the specific licence category. A specific licence is issued to a named applicant in respect of a named transaction or set of transactions. It is not transferable. The licensing power derives from SAMLA and is exercised through the relevant thematic sanctions regulations; the regulations set out the statutory licensing grounds, of which the wind-down ground is typically one distinct head. Compliance practitioners should note that the licensing grounds differ between regimes: a ground available under one thematic regulation is not automatically available under another.
OFSI also publishes guidance on how it approaches licence applications. That guidance is not legally binding but is highly material: in our experience, applications that do not address the guidance's key questions in the order OFSI expects them to be addressed tend to generate avoidable correspondence rounds and extend timelines significantly.
Who qualifies for a wind-down authorisation – and what does the eligibility test actually require?
The wind-down licensing ground is typically available where a contract or transaction was entered into before the relevant designation was made, and where the purpose of the licence is to allow that pre-existing position to be wound down in an orderly way rather than to generate new economic benefit for a designated person. Three elements define the core test.
First, pre-designation origin: the contract, obligation, or relationship must genuinely pre-date the listing event. A commitment entered into after the designation – even if in good faith without knowledge of the listing – will ordinarily not qualify. This is why the date and time of a designation relative to the date of contract execution matters in the application evidence.
Second, genuine wind-down purpose: the activity permitted must be directed toward reducing or extinguishing the contractual position, not toward maintaining or expanding it. A payment of an outstanding invoice qualifies; entering a replacement order with the same counterparty does not. OFSI will look through the label; if the practical effect of the licence use is to continue a commercial relationship rather than terminate it, the application is unlikely to succeed.
Third, proportionality of scope and duration: the wind-down period requested must be proportionate to the complexity of the exit. A short supply contract may warrant a licence window of a few weeks. A complex financial instrument or a multi-party construction project may require a longer period. OFSI will expect the applicant to explain, with specifics, why the requested duration is no longer than necessary. Over-ambitious timelines without supporting evidence are a common reason for reduced licence terms or additional questioning.
In our practice, businesses often underestimate how much documentary evidence is required to establish these three elements to OFSI's satisfaction. A well-evidenced application is not simply a covering letter; it is a structured submission that stands alone as the basis for the decision.
Step-by-step: how to prepare and submit a wind-down authorisation application to OFSI
Preparing a wind-down authorisation application is a structured process, and each step produces evidence that feeds the next. The following sequence reflects the approach that has produced the most efficient outcomes in our cross-border practice.
Step 1 – Screen and confirm the designation. Before filing anything, confirm that the counterparty is designated under the specific UK thematic regulation in question. Check the UK Consolidated List, note the exact date and time of the designation, and identify the thematic regime. A single counterparty can appear on multiple lists – UK, OFAC's SDN List (OFAC's list of Specially Designated Nationals and blocked persons), EU – but the UK wind-down ground is assessed under UK law alone. Do not conflate UK and EU designations: they may differ in scope, timing, or the available licensing grounds.
Step 2 – Map the exposure. Prepare a complete schedule of every contract, obligation, payment, asset, or transaction affected by the designation. Include reference numbers, counterparty names, amounts or asset values, contractual completion dates, and governing law. This schedule forms the factual core of the application and prevents the application being sent back because OFSI cannot determine the full scope of the wind-down.
Step 3 – Assess the applicable licensing ground. Identify which specific licensing ground under the relevant thematic regulations applies to the wind-down. This sounds technical, but it matters: if you apply under the wrong ground, OFSI may refuse on that ground even if another ground is available. Where the applicable ground is not obvious, a preliminary assessment by sanctions counsel will save time.
Step 4 – Assemble the supporting evidence. The evidence package should include: copies of the relevant contracts; documentation establishing the pre-designation execution date; a clear narrative explaining why the duration and scope of the wind-down requested are proportionate; and, where the applicant is a financial institution, the relevant transaction documentation and account records. If third parties (for example, a bank acting as intermediary) are involved in the wind-down, their consent or awareness should be noted.
Step 5 – Draft the application letter. The application letter must address OFSI's published guidance questions directly and in the expected order. It should identify: the applicant; the designated person; the contractual background; the specific licensing ground relied on; the transactions or payments for which authorisation is sought; the requested licence period; and a proportionality explanation. OFSI's guidance makes clear that incomplete applications will not be processed.
Step 6 – Submit and manage the review. Applications are submitted to OFSI in writing. OFSI's published target for processing licence applications is a statutory target of 28 calendar days for straightforward cases; complex applications may take longer, and OFSI may issue questions that pause the clock. Applicants should be prepared to respond promptly and fully to any queries: delay in responding is a common cause of extended timelines. Do not conduct the wind-down activity while the application is pending unless a general licence or other specific authorisation already covers it.
Step 7 – Implement the authorisation within its terms. Once issued, the licence specifies exactly what is and is not permitted, and for how long. Implement only the authorised activity. Keep full records of every action taken under the licence. OFSI expects record-keeping for compliance-enforcement purposes, and firms that cannot demonstrate compliance with licence terms face enforcement risk even if the underlying activity was authorised.
The position above covers the standard application path. Your specific facts – the counterparty, the contract structure, the thematic regime, the presence of multiple jurisdictions – will shape the analysis and may require a different approach.

How does the OFSI wind-down process compare with OFAC and EU equivalents?
A business operating across the UK, US, and EU cannot treat an OFSI wind-down authorisation as sufficient protection if the same counterparty is also designated under OFAC or an EU Council regulation. Each regime operates independently, and the authorisation of one regulator does not bind the others. This is the most important cross-border point in this guide.
Under OFAC, the equivalent mechanism is a specific licence issued by the Office of Foreign Assets Control under the applicable programme regulations and IEEPA. The OFAC licensing process differs from OFSI's in several material respects. OFAC's licensing standards are expressed in its guidance documents and programme-specific guidance notes, not in a single statute equivalent to SAMLA. OFAC's review timelines are not subject to the same statutory target as OFSI's. In our cross-border practice, we regularly advise clients that OFAC applications for the same underlying transaction require a separately structured submission – the factual package is largely the same, but the framing, the legal ground relied on, and the regulatory interlocutor are different. Filing an OFSI licence application and assuming it resolves the US position is a significant compliance gap.
Under the EU, the wind-down equivalent is a derogation authorised by the competent authority of the relevant member state under the applicable Council regulation. The EU regime differs from both OFSI and OFAC in a further important respect: the 27 member states each have their own competent authority, and while they apply the same underlying Council regulation, their administrative practices and timelines vary. A UK business with an EU subsidiary, or with payments routed through an EU bank, will need to consider whether the EU authority with jurisdiction over those specific elements also requires a derogation. Relying on an OFSI licence to cover an EU-regulated payment is not a valid approach.
What convergence exists between the regimes? All three share the same basic policy logic: wind-down authorisations are permitted because an abrupt prohibition on all pre-existing activity would impose disproportionate harm on innocent counterparties, and the authorisation period is designed to be temporary and bounded. But the technical legal requirements, the evidence standards, the timelines, and the scope of permitted activity can all differ. Where a transaction straddles all three regimes, parallel applications should be filed, managed together, and monitored carefully. A single breach under any one of the three regimes carries its own enforcement consequences.
The Swiss SECO regime and the regimes of Canada, Australia, Singapore, and Japan also have wind-down or derogation mechanisms for pre-existing contracts. These regimes generally follow a similar policy logic – permitting orderly exit rather than abrupt termination – but the procedural requirements and the responsible authorities differ. Businesses with supply chains or financial flows touching those jurisdictions should verify whether separate authorisations are required there too.
If a transaction has already been flagged, or a filing has been refused or returned as incomplete, early specialist review can preserve options that narrow with time. For a cross-regime assessment, contact Calder & Vance at info@caldervance.com.
What are the main risk flags and common errors in OFSI wind-down applications?
The most frequently encountered errors in OFSI wind-down applications fall into four clusters, and each can delay or defeat an application that would otherwise succeed.
Risk flag 1 – Acting before obtaining a licence. The assumption that a wind-down is inherently permissible, and that the licence merely formalises it, is incorrect. Any payment to, or dealing with property of, a designated person without a licence (or a general licence covering that specific activity) is a potential breach – even if the underlying purpose is to wind down a pre-existing position. OFSI has enforcement powers for strict-liability breaches as well as knowledge-based ones. If you are in any doubt whether interim activity is covered, stop and seek advice.
Risk flag 2 – Incomplete or unstructured applications. OFSI will not process an application that does not set out the key information it needs to make a decision. Incomplete applications are returned, adding weeks to the timeline. The most common omissions are: failure to identify the specific licensing ground; absence of the pre-designation contract evidence; and a proportionality statement that is generic rather than specific to the facts. Applications that read as if they were drafted without reference to OFSI's published guidance tend to generate extensive correspondence rounds.
Risk flag 3 – Treating the UK designation as the only relevant one. As set out above, a counterparty designated under UK sanctions may simultaneously be designated under OFAC, an EU Council regulation, or both. Filing only with OFSI while continuing to make payments through US-dollar clearing or an EU correspondent bank creates a significant exposure under those regimes without realising it. The ownership and control question (the UK and EU test for whether a non-listed entity is caught through a listed person) also requires separate analysis under each regime's standard.
Risk flag 4 – Failing to implement within the licence terms. A licence authorises exactly and only what it says. Exceeding the licence – making a payment of an amount larger than specified, paying outside the permitted period, or making a payment to an entity not named in the licence – is itself a potential breach. After a licence is received, it must be read carefully, implemented precisely, and documented fully. A voluntary self-disclosure or VSD (a voluntary report of a potential breach to a regulator) may mitigate enforcement consequences in appropriate cases, but it does not undo the breach.
Compliance counsel will also note a structural risk that sits below the level of individual errors: the temptation to treat the wind-down authorisation as a durable commercial licence. Wind-down authorisations are time-limited by design. Using the licence period to renegotiate terms, extend scope, or maintain a relationship under another contractual label will draw scrutiny. OFSI and other regulators have the power to investigate use of licences, and misuse of a licence can in itself constitute a sanctionable breach.
A myth worth correcting: "once the licence is granted, the risk is managed"
A common assumption among compliance teams is that obtaining the OFSI wind-down authorisation resolves the sanctions exposure. It does not. The licence resolves the UK financial sanctions exposure in respect of the specific activity it covers, during the period it covers, provided it is implemented in exact compliance with its terms. The following risks remain live:
- Parallel OFAC exposure if any US-nexus element exists (US-dollar payments, US-person involvement, US-origin goods).
- Parallel EU exposure if an EU-regulated entity or payment channel is involved.
- Ownership and control risks – the designated person may own or control other entities in the supply chain that are not themselves listed but are caught through the ownership test.
- The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) may catch further entities not identified in the original screening.
- Export-control obligations: where the wind-down involves the transfer of goods, technology, or software, a separate export licence under the Export Control Order or the EAR (US Export Administration Regulations) may be required independently of the financial sanctions licence.
- Reputational and correspondent-banking risk: counterparty banks may refuse to process transactions even under a valid OFSI licence if those transactions do not pass their own internal compliance standards.
In our experience, businesses that treat the OFSI licence as a full stop rather than as one element in a larger compliance analysis are the ones that face follow-on difficulties. The licence is a necessary condition for the UK position; it is rarely a sufficient condition for the full cross-border picture.
A micro-scenario illustrates the point. In a recent matter, a logistics business held a multi-year service agreement with a freight forwarding company. Following a UK designation of one of that company's shareholders, the logistics business applied for and obtained an OFSI wind-down authorisation. The wind-down was conducted in compliance with the OFSI licence terms. However, one tranche of payments flowed through a US-correspondent bank. That created an independent OFAC exposure that required a separate licensing review. We supported the OFAC assessment and, where needed, advised on the appropriate reporting position. The lesson: the OFSI licence resolved the UK position; the US position required its own analysis.
