A payment processor in the United States receives a wire transfer from a counterparty whose parent company was designated last quarter. The funds arrive, the system flags the transaction, and the balance is blocked pending review. Now what? The compliance team knows the money cannot be released without authorisation – but the path from "blocked" to "unblocked" is rarely straightforward.
The release of blocked funds under OFAC rules requires either a specific licence authorising the transaction or, in limited circumstances, a qualifying general licence that already covers it. OFAC administers the blocking and unblocking regime under authority granted by IEEPA and related statutes. Where no general licence applies, the holder of the blocked property must apply for a specific licence, meet OFAC's stated licensing policy for the relevant programme, and in many cases demonstrate that the funds do not ultimately benefit a sanctioned person or entity.
This briefing covers who administers the regime, the governing legal authority, what blocking actually prohibits, how the specific-licence process works, how the OFAC approach compares to OFSI and the EU, and the risk flags that tell a business it is time to involve sanctions counsel.
Who administers OFAC and what legal authority supports the blocking regime?
OFAC – the Office of Foreign Assets Control, a bureau of the US Treasury – is the authority responsible for administering and enforcing US economic sanctions, including the requirement to block and hold funds. OFAC acts under powers delegated by the President through executive orders issued under IEEPA, the Trading with the Enemy Act (TWEA), and a small number of country-specific statutes. The blocking obligation is the legal foundation: once a transaction involves a designated person or a blocked jurisdiction, the property must be frozen rather than returned or forwarded.
Blocking is not a discretionary act. A US person – and in many circumstances a non-US person subject to US jurisdiction through dollar clearing or correspondent banking – who receives property in which a designated person has an interest must hold it. The receiving institution becomes the custodian, not the owner. Its role is to freeze, report, and await instruction from OFAC. What it cannot do is unilaterally release the funds, return them to the sender, or offset them against a commercial debt.
The reporting obligation runs in parallel. Within a short statutory window after the blocking event, the holder must file a blocked-property report with OFAC. Failure to report is itself a potential violation, separate from any question about the underlying transaction. In our experience, compliance teams sometimes focus so heavily on the commercial problem – the stalled payment, the unhappy counterparty – that they miss this procedural requirement until well after the deadline.

What does blocking actually prohibit?
Blocking prohibits any dealing in, transfer of, payment from, export of, or withdrawal from blocked property, unless OFAC has issued an authorisation. The prohibition is comprehensive. It covers the initial receipt of funds from a blocked source, any onward payment, the use of blocked funds as security, and the simple act of returning them without a licence.
There is a subtlety that catches many businesses. The prohibition applies to property in which a designated person has any interest – not only property they own outright. A partial beneficial interest, a contractual right to receive funds, or a pledge over the account can all be enough. The question "does the designated person have an interest in this property?" is broader than "do they own it?"
The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) extends the reach further. Where the original payment comes from an entity that is not itself listed but is owned 50 percent or more in aggregate by listed persons, the funds are treated as blocked property from the moment of receipt. Compliance teams that screen only against the SDN List (OFAC's list of Specially Designated Nationals and blocked persons) without tracing the ownership chain behind the counterparty will miss exactly this exposure.
Do the prohibitions apply equally to foreign branches and subsidiaries of US firms? The answer depends on the programme. Some OFAC programmes apply only to US persons; others extend to US-owned or controlled foreign entities. That distinction – which the applicable OFAC programme regulations define – is material to any decision about whether a foreign-booked transaction is blocked at all.
How does the specific-licence process work for releasing blocked funds?
A specific licence (a case-by-case authorisation from OFAC to conduct an otherwise prohibited transaction) is the primary route to releasing blocked funds where no general licence already applies. The application is submitted to OFAC through its official licensing portal. It must identify the parties, the nature and amount of the blocked property, the factual basis for the request, and the specific relief sought.
OFAC evaluates applications against its stated licensing policy for the relevant sanctions programme. That policy varies considerably. For some programmes, OFAC routinely issues licences for transactions that serve humanitarian ends, unwind pre-designation contracts, or benefit a US person who holds a legitimate interest in the blocked property. For others, the policy is restrictive, and applications for commercial releases are rarely granted. Understanding which policy applies – and framing the application accordingly – is a practical prerequisite to a credible filing.
The process is not quick. Processing times are measured in months, not weeks, for contested or complex applications. OFAC may ask for additional information. It may issue a partial licence, covering some but not all of the blocked property. And it can decline without detailed reasons. In our practice, we regularly advise clients that the strength of the application depends less on the volume of supporting documents and more on the precision of the policy argument: why, specifically, does releasing these funds serve the objectives of the programme rather than undermine them?
A general licence (a standing authorisation that permits a defined category of transactions without a separate application) can sometimes cover a release of blocked funds – for example, where the transaction is for the payment of certain legal fees, the settlement of pre-designation contracts below a defined threshold, or the winding down of a business relationship during a transition period. But general licences are programme-specific and condition-laden. Relying on one without careful analysis of each condition is a compliance risk in itself.
A note on the timing of the application. Where funds have been blocked and the counterparty is pressing for payment or return, the business faces a creditor relationship that is suspended for the duration of the licence review. Interest, penalties, and contractual obligations continue to run in some cases even where performance is excused by force majeure or sanctions clauses. Getting the application in promptly and managing the counterparty's expectations simultaneously is a practical judgement call that counsel can help structure.
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.
How does the OFAC approach compare to OFSI and the EU regime?
The OFAC regime is one of several that can apply to the same blocked funds. A dollar-clearing transaction may be subject to OFAC rules. The same transaction, involving a UK entity, may simultaneously engage OFSI, the UK financial-sanctions authority under the Sanctions and Anti-Money Laundering Act (SAMLA). And where an EU-nexus bank is in the payment chain, the relevant EU Council regulation may independently require the assets to be frozen.
The ownership-and-control tests diverge. OFAC applies the 50 percent rule mechanically: if listed persons own 50 percent or more in aggregate, the entity is blocked. OFSI and the EU apply an ownership and control test (the UK and EU standard for whether a non-listed entity is caught through a listed person) that looks beyond formal ownership to de facto control. A listed person who holds only 40 percent of an entity but directs its management decisions may cause that entity to be caught under the UK and EU tests, even while the same entity falls outside OFAC's 50 percent threshold. That divergence creates asymmetric exposure in transactions that touch multiple jurisdictions.
Licensing routes also differ. OFSI issues specific licences on a case-by-case basis, much as OFAC does, but the procedural requirements, the assessment criteria, and the licensing policy for each UK sanctions programme are set under SAMLA and the relevant thematic regulations rather than IEEPA. The EU Council regulations contain their own authorisation procedures, which in many cases delegate licensing decisions to member-state competent authorities rather than a central EU body. An application that succeeds before OFAC does not automatically authorise the transaction under OFSI or the EU regime.
There is also the interaction with the EU Blocking Regulation, which in certain circumstances prohibits EU persons from complying with specified US extra-territorial sanctions measures and creates a duty to notify the European Commission of any effect from those measures. Where blocked funds sit in an EU entity that is simultaneously subject to US secondary-sanctions pressure, the compliance team faces a genuinely contradictory set of obligations. The resolution is not simple, and it is one we have acted on for clients caught between the two regimes.
For businesses with a cross-border footprint, the practical implication is this: a release of blocked funds that satisfies OFAC may still leave the transaction prohibited in the UK or EU. A complete analysis maps the funds flow against every regime that has jurisdiction over any party in the chain. Taking a siloed, one-regime view is a frequent source of residual exposure.
What are the reporting obligations and record-keeping requirements?
The holder of blocked property carries two distinct administrative obligations: reporting the blocking event to OFAC and maintaining records that document the blocked property and the steps taken to comply. Both are independent of any licensing application and both are mandatory from the moment the property is blocked.
The reporting window is short. OFAC regulations require a report to be filed promptly after a blocking event – the exact deadline is programme-specific, so the holder should identify the applicable programme and its rule at the moment of blocking. An initial report at the time of blocking and an annual report of all blocked property held as of a fixed date are both required under standard OFAC rules. Missing either is an independent violation.
Record-keeping is a long-term obligation. OFAC's rules require records relating to blocked property to be maintained for a period generally stated as five years from the date of the transaction. That extends well beyond the resolution of any licensing application. In practice, businesses should treat blocked-property records as a distinct file maintained separately from normal transactional records, accessible for examination by OFAC in any subsequent review or enforcement inquiry.
What records matter most? The documentation that captures the moment of blocking: the transaction record, the screening result that flagged the designated interest, the decision to block rather than process, the internal escalation trail, and the timestamp of the OFAC report. Each of these becomes relevant if OFAC examines whether the business complied promptly and accurately.
What are the enforcement risks if blocked funds are not handled correctly?
A failure to block and hold property that should be blocked is a strict-liability violation under most OFAC programme regulations. It does not matter that the business was unaware of the designated interest, that screening tools failed to flag the connection, or that the transaction was completed in good faith. Strict liability means that the absence of intent does not preclude a finding of violation. It does, however, affect the civil penalty calculation under OFAC's enforcement guidelines.
OFAC's penalty framework distinguishes between egregious and non-egregious violations, and between those made subject to a VSD (voluntary self-disclosure to a regulator) and those that are not. A timely VSD, accompanied by a well-structured self-disclosure package, is a meaningful mitigant in civil penalty proceedings. It does not guarantee a favourable outcome, but in our experience the penalty differential between disclosed and undisclosed violations is material – and OFAC's published enforcement guidelines confirm this distinction.
The alternative – sitting on an apparent violation without reporting – compounds the exposure. A subsequent examination, triggered by a routine examination or by a report from the correspondent bank, may reveal both the underlying violation and the failure to self-disclose. That combination is treated more seriously than a disclosed violation of equivalent severity.
The enforcement picture also has a criminal dimension. Where funds are knowingly released without authorisation, or where a business structures transactions to obscure a designated interest – a form of evasion the firm does not advise on and does not assist with – DOJ can and does bring criminal charges under the export-control statutes and sanctions regulations. The civil and criminal tracks are independent of one another.
Common misconceptions and when to involve sanctions counsel
Several persistent misconceptions cause businesses to mishandle blocked-funds situations. The first is that blocking is a temporary administrative hold that resolves itself if the counterparty provides a correction or explanation. It does not. Blocking takes effect by operation of law at the moment a designated interest is identified. Only OFAC can authorise a release.
The second misconception – a variant of the first – is that returning the funds to the sender resolves the compliance problem. It does not. Returning blocked funds to the sender without a licence is itself a prohibited transfer. The funds must stay with the holder until OFAC issues authorisation. How the holder manages the relationship with the counterparty in the interim is a separate question, but the compliance answer is always "hold and report."
Third, some businesses assume that because the counterparty is not itself listed – only a shareholder is listed – the 50 percent rule cannot apply. But as noted above, the rule aggregates holdings across all listed persons. Two listed persons each holding below the threshold can together trigger it. Screening only for direct matches on the SDN List, without ownership-chain analysis, is a structural gap in any programme handling high-volume cross-border payments.
When should counsel be involved? The short answer: before the first substantive communication with OFAC. Decisions made in the first 48 to 72 hours after a blocking event – what to report, how to characterise the facts, whether to seek a specific licence immediately or await further ownership analysis – shape the record that OFAC will examine in any subsequent review. In our experience, businesses that involve sanctions counsel at the point of blocking preserve significantly more options than those that attempt to manage OFAC communications without legal support before engaging lawyers only when problems arise.
We regularly advise compliance teams working through their first OFAC blocking event, and we have acted for financial institutions, trading companies, and fintech businesses navigating multi-programme blocking scenarios where the funds touch OFAC, OFSI, and EU obligations simultaneously. The practical steps are manageable with the right structure. Without it, the exposure widens quickly.
