A trading company active between London and Brussels learns that a key supplier has been designated under both UK and EU sanctions. Existing contracts are part-complete. Goods are in transit. Payment obligations are due. The business has days – not weeks – to determine whether it can lawfully wind down its exposure before every outstanding transaction becomes a potential breach.
Wind-down authorisations permit a business to complete or exit existing contractual arrangements with a newly designated counterparty within a defined period, without obtaining a full specific licence. Under OFSI they arise from the relevant thematic sanctions regulations, administered by His Majesty's Treasury; under the EU they derive from the applicable Council Regulation. The two regimes share a common objective but diverge sharply on scope, duration, conditions, and the risk consequences of a misstep.
This analysis maps those divergences point by point, identifies the practical risk flags, and sets out what a cross-border business should do the moment a counterparty appears on either list.
What are wind-down authorisations, and why do they exist?
A wind-down authorisation (sometimes called a wind-down period or a close-out licence) is a time-limited permission that allows a person otherwise subject to a financial-sanctions prohibition to take steps that are strictly necessary to complete, terminate, or assign an existing contractual relationship with a designated person or entity. The authorisation does not permit new business with the designated party. It exists to reduce the collateral disruption to innocent third parties – suppliers, employees, and counterparties – who were bound to the designee before the designation took effect.
Both OFSI and the EU recognise that an abrupt prohibition, applied with no wind-down relief, can produce disproportionate harm. But their design choices differ. OFSI treats wind-down as a licensing matter, administered by the Office of Financial Sanctions Implementation within HM Treasury. The EU embeds wind-down provisions directly in the applicable Council Regulation, making them a form of automatic or general authorisation in some programmes – and leaving others to rely on the national-competent-authority licensing route.
The difference in design has a direct operational consequence. Under OFSI, a business typically needs to engage HM Treasury before it can rely on the authorisation. Under certain EU programmes, the authorisation may be self-executing within defined parameters, meaning a business acts first and documents its reliance afterwards. That distinction alone can alter a cross-border compliance plan considerably.
In our experience, businesses operating across both regimes routinely underestimate how far the procedural differences can matter in the first seventy-two hours after a designation is published. The assumption that "the EU and the UK are broadly the same" is one of the more persistent and costly myths in post-Brexit sanctions compliance.
How does OFSI's wind-down approach work in practice?
OFSI administers wind-down authorisations through its licensing function under SAMLA – the Sanctions and Anti-Money Laundering Act – and the applicable thematic regulations. The starting point is that, once a person or entity is designated under the relevant UK sanctions programme, dealings that would transfer funds or economic resources to or for the benefit of the designated person are prohibited unless licensed. Wind-down activity is not automatically exempt.
OFSI issues specific licences (case-by-case authorisations to conduct an otherwise prohibited transaction) and, in some programmes, general licences (standing authorisations that permit a defined category of transactions without a separate application). Wind-down general licences, where they exist, set out permitted categories of transaction, the applicable time window, and the conditions – including record-keeping and, in some cases, reporting. Where no general licence applies, an applicant must seek a specific licence from OFSI, identifying the contractual relationship, the steps required to exit it, and why those steps are strictly necessary.
OFSI's published guidance makes clear that "strictly necessary" is interpreted narrowly. The purpose is contractual exit, not contractual performance for commercial advantage. A business that uses a wind-down window to take delivery of goods it does not need – purely because the price is favourable – is likely to find that the authorisation does not cover it.
The position above covers the standard case. Your specific contractual profile – the counterparty, the goods or services involved, the route, the outstanding payment obligations – will affect which OFSI licensing category applies and whether a general licence is in force for your programme.
How does the EU wind-down regime differ?
The EU approach to wind-down authorisations is governed by the applicable Council Regulation for each sanctions programme, with implementation by the competent authority of each member state. There is no single EU body equivalent to OFSI. Where a UK business applies to OFSI, an EU business applies to its own national regulator – which may be the national treasury, the central bank, or a dedicated financial-intelligence unit depending on the member state.
The substantive divergence lies in three areas.
First, several EU Council Regulations contain provisions that are structured as automatic wind-down permissions, operative within a defined period from the date of designation, for transactions that meet specified conditions. A business that satisfies those conditions may be able to proceed without a prior licence application, provided it keeps adequate records and can demonstrate compliance if challenged. OFSI's programmes rarely operate on this self-executing basis; OFSI tends to require engagement before or immediately at the point of reliance.
Second, the duration of the wind-down window varies by programme and, in the EU, by the specific regulation. Some EU programmes set a short fixed period; others allow a competent authority to extend on application. OFSI's wind-down timelines are set by each general licence (where one exists) or determined case by case in specific licences. As of June 2026, businesses should verify the current position for each programme before relying on any assumed duration, as these provisions are subject to amendment without the fanfare of a full regulatory update.
Third, the conditions attached to the authorisation differ. EU regulations frequently list the permitted categories of payment with greater specificity – wages, professional fees, service charges in connection with contractual close-out, for example – and prohibit any payment that does not fall within a named category. OFSI's general licences tend to set the condition in terms of purpose (exit or completion) and leave more room for judgment, which is simultaneously more flexible and more uncertain.
What happens when both regimes apply simultaneously? For a business that is established in the UK and has EU-based operations or EU-currency payment flows, both sets of rules bite. The stricter prohibition governs. If the EU regulation permits a payment that the applicable OFSI general licence does not, the OFSI restriction prevails for the UK entity. The reverse is also true. Cross-border businesses cannot cherry-pick.
Where are the practical risk flags?
Risk under wind-down authorisations concentrates at four points.
The first is scope creep. Wind-down is for contractual exit, not for additional performance. A payment made under a wind-down authorisation that in fact advances the commercial relationship – rather than terminates it – will not be covered. OFSI's enforcement guidance makes clear that reliance on a licence that does not in fact authorise the conduct is not a defence; it is a separate breach. In our practice, we have seen businesses make payments they genuinely believed were covered, only to discover on review that the transaction fell outside the permitted purpose.
The second risk flag is timing. Designations are published with immediate effect. A business that waits to identify all outstanding obligations before acting loses days it cannot recover. The wind-down window starts from the designation date, not from the date the business becomes aware of it. This is particularly acute where a counterparty operates under a corporate name that does not obviously match the listing.
The third risk flag is documentation. Both OFSI and the EU require that businesses relying on a wind-down authorisation maintain records sufficient to demonstrate that each transaction was within scope. Under OFSI's enforcement policy, good-faith reliance supported by contemporaneous documentation is a material factor in determining whether a penalty is appropriate and at what level. Without records, a business cannot demonstrate good faith.
The fourth risk flag is the interaction with other regimes. A UK business winding down an EU-designated counterparty relationship may find that its US correspondent bank declines to process the settlement, because the US has not issued equivalent wind-down relief, or because the US designation is on different terms. Secondary-sanctions risk from OFAC's extraterritorial reach is live for businesses with US-dollar flows, US entities in their corporate group, or US-person involvement in the transaction chain.
If a transaction has already been flagged, or a filing has been refused, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com to discuss the position.
A divergence map: OFSI vs EU side by side
The following addresses the principal points of divergence that practitioners and compliance teams need to work through on a dual-jurisdiction matter.
Governing authority. OFSI administers the UK position centrally. The EU position is administered by the competent authority of each member state, producing variation in practice even where the regulation is identical in text. A business with operations in three EU member states may face three different processing styles.
Self-execution. Some EU regulations permit automatic reliance within the wind-down window without prior application, subject to conditions. OFSI's position generally requires active engagement – either reliance on a published general licence (where one exists and is current) or a specific licence application before or during the wind-down activity.
Permitted activities. OFSI's general licences (where applicable) tend to be framed purposively – exit and completion. EU regulation tends to list permitted payment categories with more precision. In practice, OFSI's approach leaves room for judgment calls; the EU approach requires a cleaner fit to the listed category.
Duration. Both regimes set time windows, but the length and any extension mechanism differ by programme. There is no universal "wind-down period" applicable across all UK or EU sanctions programmes. The window must be verified programme by programme.
Reporting and record-keeping. OFSI's general licences typically impose reporting obligations and record-keeping for five years from the date of the transaction. EU reporting requirements vary by member-state implementation. Both regimes treat documentation as a prerequisite for any enforcement-mitigation argument.
Penalties. OFSI can impose civil monetary penalties for breach of a financial sanction. The EU civil-penalty regime operates at member-state level and varies considerably. Criminal exposure exists in both jurisdictions. Neither regime provides immunity from penalty simply because the business attempted a wind-down and made an error of scope.
Interaction with OFAC. Neither OFSI nor the EU provides any cover against OFAC liability. Where OFAC has designated the same counterparty – or a connected person – the US position must be checked in parallel. OFAC's secondary-sanctions reach extends to non-US persons in defined circumstances, making this analysis mandatory for businesses with US-nexus.
The myth of equivalence – and why it matters post-Brexit
A persistent assumption among in-house teams is that post-Brexit UK sanctions are broadly equivalent to EU sanctions, and that wind-down provisions on one side translate directly to the other. This assumption is incorrect, and acting on it is one of the more common sources of inadvertent breach that we encounter.
The UK and EU sanctioned-entity lists are not identical. Since the Sanctions and Anti-Money Laundering Act came into force, the UK has made designation decisions independently of the EU. A counterparty designated by the EU but not the UK falls outside OFSI's prohibitions (absent other grounds). The reverse is also true. A business operating across both jurisdictions must run separate screening against each list, because a hit on one is not a hit on the other.
More relevantly for wind-down purposes: the UK and EU have not always published wind-down relief in corresponding form for corresponding programmes. Where the EU has issued a general permission for close-out transactions within a specified window, OFSI may not have done so for the UK programme covering the same sector. A business that assumes UK equivalence and acts on the EU provision alone risks a breach of UK financial sanctions.
In a recent matter, a financial-services business operating from both London and an EU member state concluded that a wind-down general permission published by the EU covered its UK entity's close-out transactions. It did not. We identified the gap on review of the transaction documentation before any payment had been processed, and the client applied to OFSI for a specific licence covering the UK leg. The matter concluded without enforcement action. Earlier identification of the divergence would have preserved more time in hand.

When should a cross-border business involve counsel?
The answer is: before the first wind-down payment is processed, not after. Wind-down authorisations appear deceptively simple in the regulatory text. In practice they involve a sequence of judgments – is the activity strictly necessary? Is the applicable general licence still current and in force for this programme? Does the EU self-executing provision actually apply to this category of payment? What are the US-nexus implications? – each of which carries enforcement risk if resolved incorrectly.
Counsel should be involved at the point of designation, or immediately on a business identifying a counterparty on a relevant list. The tasks at that stage are: confirm which regimes apply to the business and the transaction; identify whether a general licence is in force for the relevant programme in each jurisdiction; determine whether the wind-down activity in question falls within the scope of any such licence; and, where it does not, prepare and submit a specific licence application with supporting documentation.
Where a business has already made payments it now believes may not have been covered, the analysis shifts to enforcement defence. That involves scoping the apparent violation, assessing whether a VSD (voluntary self-disclosure to the relevant regulator) is appropriate, and managing the process with OFSI or the relevant member-state authority. In our cross-border practice, early VSD consistently produces better outcomes than a reactive response to an investigation.
