A multinational trading house has just discovered that a counterparty it has dealt with for three years appears on OFAC's SDN List (OFAC's list of Specially Designated Nationals and blocked persons). The relationship must end. But the contracts are mid-performance, the receivables are outstanding, and the goods are in transit. How does the business exit cleanly, without the wind-down process itself constituting a prohibited transaction?
Winding down sanctioned exposure under OFAC rules requires a disciplined, legally structured exit from any transaction or relationship that has become impermissible because of a designation or a change in sanctions scope. OFAC, operating under authorities including IEEPA and TWEA, administers these requirements and has the power to authorise wind-down activity through general licences (standing authorisations that permit a defined category of transactions without a separate application) or specific licences (case-by-case authorisations for otherwise prohibited activity). Where no licence applies, the prohibited transaction must stop immediately and any blocked property must be reported and frozen.
This briefing sets out the governing authority, the key prohibitions, the licensing and wind-down procedure, the cross-border dimension, the enforcement risk, and the risk flags that most commonly produce violations during an exit process.
Who administers OFAC and what is its legal authority?
OFAC – the Office of Foreign Assets Control within the US Department of the Treasury – administers US economic sanctions under statutory authorities that include the International Emergency Economic Powers Act, the Trading with the Enemy Act, and country-specific and thematic acts of Congress. Its authority is broad and does not require a US nexus in every case; the extraterritorial reach of certain programmes means that non-US persons can be exposed through US dollar clearing, the involvement of a US person, or the use of US-origin goods or technology.
OFAC maintains the SDN List, the Sectoral Sanctions Identifications List (SSI List – identifying persons subject to targeted, sector-specific restrictions rather than full blocking), and several other lists. A wind-down obligation can be triggered by a new SDN designation, an amendment to a general licence that removes a previously permitted category, or a transaction that the business only later recognises was impermissible from inception. As of January 2026, OFAC administers more than thirty active sanctions programmes covering specific countries, regions, individuals, and thematic areas.
The position above covers the standard case. Your facts – the counterparty, the goods, the route, the currency, and the programme in play – change the analysis significantly. For a confidential review of your exposure, contact Calder & Vance at info@caldervance.com.
What does OFAC prohibit and how does that shape a wind-down?
OFAC prohibitions generally fall into two categories: blocking prohibitions, which freeze all property and property interests of a designated person in which a US person has a stake, and transactional prohibitions, which bar specific dealings regardless of whether full blocking applies. Both categories are directly relevant to wind-down planning.
Under blocking prohibitions, any property or property interests in which an SDN has an ownership or other interest must be reported to OFAC within a short statutory window and held in a blocked account. Releasing that property to the SDN – even to complete a pre-existing contractual obligation – is itself a violation. The common misconception is that performance of a pre-designation contract is permissible as a matter of good faith. OFAC's position is more demanding: the designation cuts off the contract, and any further transfer of value to the SDN requires a licence.
Transactional prohibitions operate differently. They may bar new transactions with a defined sector, class of person, or counterparty without requiring full blocking. Where these restrictions apply, a business may need a wind-down licence simply to close out its existing position. The SSI List is the clearest example: a company listed there may not be fully blocked, but dealings in certain debt or equity instruments with it are prohibited, and unwinding those positions requires careful legal analysis before any action is taken.
The practical implication: a business that simply stops performing, without addressing blocked property obligations or the specific mechanics of the applicable programme, may still be in violation – and may also be creating secondary risk for its own counterparties in the supply chain.
How does a structured wind-down under OFAC work in practice?
A structured OFAC wind-down follows a logical decision sequence. Each step must be completed before the next begins, because premature action – particularly any transfer of funds or goods to or for the benefit of a blocked person – can convert a compliance problem into an enforcement exposure.
The first step is to identify the precise trigger. Is the counterparty on the SDN List, the SSI List, or caught by the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked, in the aggregate, directly or indirectly)? Has a general licence been revoked or narrowed? Or has the business been operating in a sanctions programme scope that it only now recognises?
The second step is to audit the exposure. This means mapping every open contract, receivable, payable, in-transit shipment, digital asset holding, or other property interest that touches the relevant person or programme. In our experience, businesses almost always underestimate the breadth of the exposure at this stage. Subsidiaries, joint ventures, and correspondent relationships may all hold relevant interests.
The third step is to identify the applicable licence authority. OFAC regularly issues general licences that permit wind-down activity for a defined period, typically measured in days or weeks from the effective date of the designation or programme change. These windows vary by programme and are published in the Federal Register and on OFAC's website. If no general licence covers the activity, a specific-licence application is required. Specific-licence applications must describe the transaction in detail, identify all parties, explain why the licence is necessary, and set out the proposed mechanics of the wind-down. OFAC's review timelines for specific licences vary by programme and the complexity of the request; there is no statutory deadline by which OFAC must respond, and timelines can extend to several months in complex matters.
The fourth step is to execute the permitted wind-down within the authorised scope – and to document every step. Documentation is not optional. If an enforcement query arises, the contemporaneous record of the legal basis for each step is the primary defence.
The fifth step, where blocked property is involved, is to file the required blocked-property report with OFAC and ensure that the funds or assets are held in an appropriately designated blocked account. The reporting obligation is separate from the wind-down licence question and arises independently.
Where do OFAC requirements diverge from OFSI and EU rules – and why does it matter?
Any business managing a wind-down with cross-border dimensions will face the interaction between OFAC requirements and those of the UK's OFSI (Office of Financial Sanctions Implementation) and the EU's Council-regulation sanctions. The three regimes share broad objectives but diverge sharply on the technical rules that govern a wind-down.
The ownership and control test is the most significant divergence. OFAC applies the 50 percent rule mechanically: aggregate ownership of 50 percent or more by blocked persons triggers blocking, regardless of control. OFSI and the EU apply an ownership and control test (the UK and EU test for whether a non-listed entity is caught through a listed person) that can capture entities even where the listed person's ownership stake sits below fifty percent, if that person exercises effective control. The same corporate structure can produce different conclusions depending on which regime governs the analysis. A wind-down that satisfies OFAC's conditions may still be prohibited under the applicable EU Council regulation, or vice versa.
The licensing mechanics also differ. OFAC issues both general and specific licences. OFSI issues both general and specific licences under the applicable UK thematic sanctions regulations, but OFSI has separate statutory reporting obligations that require notification within a defined window when a firm knows or suspects it holds a sanctioned person's funds. The EU operates through member-state competent authorities, which adds a jurisdictional layer: a group with subsidiaries in multiple EU member states may need authorisations from more than one competent authority.
Where the stricter prohibition governs, a business operating across regimes must satisfy the most restrictive requirement. A wind-down structured to comply with only one regime is an incomplete wind-down.

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 your position.
What are the enforcement risks during a wind-down and when do they crystallise?
OFAC enforcement does not exempt a business from liability simply because it was trying to exit a relationship. The manner of exit – the timing, the counterparties involved, the property transferred, and the documentation maintained – determines whether the wind-down itself gives rise to an apparent violation.
The most common enforcement triggers during a wind-down are these. First, a payment made after a designation but before the business confirmed the SDN status: even a brief delay in screening creates exposure. Second, a general-licence window that was read too broadly, permitting activity that the licence did not in fact cover. Third, a failure to report blocked property within the required period. Fourth, a payment routed through a third party that the business did not identify as within the SDN's ownership chain. Fifth, a voluntary self-disclosure (VSD – a proactive report to OFAC of an apparent violation by the reporting entity) that was either delayed or filed without adequate supporting analysis, reducing its mitigating value.
OFAC's enforcement programme distinguishes between egregious and non-egregious cases. Non-egregious apparent violations that are promptly disclosed and that the firm has strong compliance processes to address are treated more favourably than matters that surface through third-party reporting or routine examination. A VSD does not guarantee a reduced penalty, but in our practice it consistently improves the range of outcomes available to a respondent. The decision to file a VSD, and the timing and content of that filing, are matters where legal advice should be taken before any disclosure is made.
Secondary-sanctions risk is a separate enforcement dimension. A non-US business that facilitates a wind-down transaction for a US-sanctioned counterparty may itself become the subject of OFAC action under secondary-sanctions authorities. This risk is not uniform across programmes: some programmes carry explicit secondary-sanctions provisions while others do not. Identifying whether the applicable programme carries secondary-sanctions exposure is a threshold question in any cross-border wind-down.
What risk flags most commonly arise in cross-border wind-downs?
Cross-border wind-downs surface a predictable set of risk flags that experienced counsel identify early and that less-prepared businesses encounter when the enforcement query has already arrived.
The first is incomplete ownership mapping. A business that screens the contractual counterparty but not the full ownership chain – including intermediate holding companies and entities in jurisdictions with limited public registry disclosure – will routinely miss the 50 percent rule trigger or the control test under OFSI and EU rules.
The second is currency denomination. OFAC's reach extends to US dollar transactions wherever they occur, because dollar clearing passes through the US financial system. A wind-down payment denominated in US dollars, processed through a US correspondent bank, engages OFAC even if both the payer and payee are non-US persons. This is the extraterritoriality mechanism that most frequently surprises trading companies and logistics businesses that consider themselves to be operating outside the US.
The third is goods and technology in transit. An export or re-export of US-origin goods or technology to a sanctioned person triggers both OFAC and BIS (Bureau of Industry and Security) jurisdiction under the EAR (Export Administration Regulations). A wind-down that addresses the financial dimension but leaves a shipment of US-origin items en route to a restricted end-user has resolved only part of the problem. The BIS Entity List (a BIS control list identifying persons subject to licence requirements for specified items) and the Denied Persons List must be checked alongside the SDN List before any goods are allowed to continue to their destination.
The fourth is digital-asset exposure. Where the sanctioned relationship involves virtual assets or dealings with a VASP (virtual-asset service provider), the wind-down mechanics are more complex. OFAC has confirmed that sanctions obligations apply to digital-asset transactions, and several SDN designations have included associated digital-wallet addresses. Unwinding a digital-asset position requires the same rigour as a fiat-currency wind-down, with additional questions around the traceability of on-chain transactions.
The fifth is the correspondent-banking chain. A firm that processes its wind-down payment through a bank with its own OFAC compliance programme may find that the payment is blocked at the correspondent level before it reaches the intended recipient account. This is not a failure of the wind-down; it is a predictable consequence of the regime. The remedy is to structure the payment route, the currency, and the timing in advance, after confirming with counsel that the proposed route is permitted. For context on how correspondent-banking relationships interact with sanctions risk, see our related briefing on correspondent banking and de-risking under OFAC.
A common misconception corrected: the "pre-existing contract" defence
One persistent misconception is that a pre-designation contract provides a complete defence to continued performance after the designation. The logic is understandable: the contract was lawful when signed; the designation is OFAC's action, not the business's; good faith should count for something.
OFAC's position does not support this reading. A designation takes effect from the moment of listing. Any transfer of value to or for the benefit of the SDN from that point – including a payment due under a pre-existing, commercially legitimate contract – is a prohibited transaction unless covered by a licence. The pre-existing contract is relevant as a mitigating factor in enforcement, and it may support the grant of a specific licence to complete the transaction in an orderly manner. But it does not, on its own, legalise continued performance.
In our experience advising clients across trading, financial services, and manufacturing sectors, this misconception is the single most common source of exposure during an unmanaged wind-down. The business continues to perform, relying on the contract, while the clock runs on the unlicensed transfers. By the time the error is identified, the violation has occurred multiple times. A prompt, licence-confirmed halt – however commercially disruptive – is always preferable to a series of unlicensed transactions.
We regularly advise clients on the specific-licence route as a structured alternative to either immediate cessation (which may itself cause financial harm) or continued unlicensed performance (which creates enforcement risk). A well-prepared specific-licence application, supported by legal analysis and a clear statement of the proposed mechanics, gives OFAC the information it needs to act. The outcome of any application depends on the facts and the programme; we do not promise a result.
