A bank holding company receives notice that one of its accounts has been frozen under OFAC sanctions. The funds are blocked, the account holder is asking questions, and the compliance team faces an immediate practical problem: what are they required to do, what are they prohibited from doing, and how long can this situation persist before legal exposure compounds? As of June 2026, OFAC-administered blocked-property rules remain one of the most operationally demanding obligations in the US sanctions regime – and one of the least well understood outside specialist practice.
Frozen-account management under OFAC rules requires a financial institution or other person holding blocked property to preserve that property in place, report it to OFAC within a short statutory window, and maintain records for a defined retention period – all without engaging in any dealing, transfer, or disposal that would constitute an unlicensed transaction. The obligation is triggered automatically by the designation of a person or entity on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons) or by another blocking order issued under the International Emergency Economic Powers Act (IEEPA). The penalty exposure for mishandling blocked property is civil and, in serious cases, criminal.
This briefing sets out who administers the regime, what the core prohibitions and obligations are, how the ownership and control analysis applies, what the licensing route looks like, how enforcement works, and where the OFAC position diverges from the UK and EU equivalents that cross-border businesses will encounter alongside it.
Who administers OFAC and what gives it authority over blocked accounts?
The Office of Foreign Assets Control, a bureau of the US Department of the Treasury, administers the US economic-sanctions regime and is the authority responsible for frozen-account management under OFAC rules. Its authority derives primarily from IEEPA, which empowers the President to declare a national emergency with respect to an unusual and extraordinary foreign threat and to block property in which a foreign country or national has an interest. Specific programme regulations issued under that authority give operational content to each sanctions programme.
The practical effect is that when OFAC designates a person and adds them to the SDN List, any US person – and in many cases any non-US person touching the US financial system – who holds, controls, or is in the process of transferring property in which that designated person has an interest must freeze that property immediately. The freeze is self-executing: no separate government order directed at the holding institution is required.
OFAC's jurisdiction extends to US persons worldwide, to transactions that clear in US dollars through a US correspondent bank, and to transactions involving US-origin goods or technology. This extraterritorial reach is one of the features that makes OFAC the primary concern for cross-border businesses operating in multiple currency zones. A non-US financial institution processing a US-dollar payment may hold a blocking obligation even if neither counterparty is US-based – that is the practical reach of the regime, and it is why foreign institutions devote substantial resources to OFAC screening.
The position above describes the standard case. Your specific facts – the account holder, the beneficial ownership chain, the currency, the transaction type – change the analysis materially.

What does OFAC prohibit in relation to blocked accounts?
The core prohibition is dealing in blocked property: once an account is frozen, the holder must not transfer, pay out, export, withdraw, or otherwise deal in or engage in any transaction involving the blocked funds without a valid OFAC licence. That prohibition applies to the account-holding institution and, importantly, to the account holder themselves. Receiving blocked funds, making payments from a blocked account, or charging fees against a blocked balance can all constitute unlicensed transactions under the applicable programme regulations.
Several categories of dealing are commonly misunderstood. First, charging ordinary account maintenance fees against a frozen balance is generally treated as a dealing that requires authorisation or a general licence – the account holder's property cannot be diminished without OFAC approval. Second, the prohibition on transfer includes constructive transfers: netting a blocked receivable against an unblocked payable, or offsetting a blocked deposit against an outstanding loan, is treated as a dealing under OFAC guidance. Third, providing services to a blocked person in connection with blocked property – for example, providing investment advice on a frozen portfolio – falls within the prohibition.
The prohibition is not limited to the underlying asset. Information provided to a blocked person about their own blocked account can, in some circumstances, constitute a service that falls within programme restrictions. In our experience, this is an area where account-holding institutions underestimate their exposure and provide more information than OFAC guidance would support without a specific licence or a relevant general licence.
What is not prohibited is equally important to understand. Holding the account open, maintaining it in frozen status, and performing purely administrative functions necessary to preserve the property are permitted and in fact required. The obligation is to conserve, not to liquidate or to close the account and return the funds.
How does the 50 percent rule apply to frozen-account management?
The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked, whether or not separately listed) extends the blocking obligation beyond directly designated account holders to entities they own or control. For an account-holding institution, this means the screening analysis cannot stop at the account holder's name: the institution must identify the beneficial owners of the account holder and assess whether any of them are designated persons whose aggregate interest reaches the threshold.
Aggregation is the point most frequently missed. Two SDN-listed persons each holding a minority stake in the same entity may together reach the 50 percent threshold, triggering a blocking obligation in respect of accounts held by that entity – even if neither listed person alone would trigger the rule. In our practice, we regularly advise institutions that have screened for direct matches but have not mapped the ownership chain to second or third-level intermediaries.
The contrast with the UK and EU positions is worth noting for cross-border practitioners. OFSI, the UK's Office of Financial Sanctions Implementation, applies both an ownership test and a control test. An entity can be caught even if no listed person owns 50 percent or more, if a listed person holds control through other means – board composition, veto rights, contractual arrangements. The EU Council regulations apply the same dual test. The practical consequence is that an entity a US institution would not block on ownership grounds may still be caught by OFSI or EU restrictions that a cross-border group must honour simultaneously. This divergence is a recurring issue in multi-jurisdictional transactions, and it is addressed in detail in our briefing on OFSI frozen-account obligations.
Beyond the 50 percent rule, institutions should note that indirect interests count. A blocked person holding a 60 percent stake in Company A, which itself holds a 90 percent stake in Company B, means Company B is blocked through Company A – the chain is followed to each level without dilution where a majority interest passes at each link.
What are the reporting and record-keeping obligations for blocked property?
The reporting obligation for blocked property is one of the most time-sensitive elements of frozen-account management under OFAC rules. Any US person who blocks funds or other property must report the blocking to OFAC within a short statutory window after the blocking occurs. The same obligation applies to the unblocking of property. Both the initial blocking report and any unblocking report must be submitted to OFAC in the form and manner prescribed by the applicable programme regulations.
Annual reporting is a second, ongoing obligation. Persons holding blocked property valued above a specified threshold must file an annual report with OFAC disclosing the nature, amount, and location of the property. These annual reports allow OFAC to maintain an accurate register of blocked assets in the US financial system and are an enforcement tool: failure to report is itself a violation independent of any underlying dealing in the property.
Record-keeping obligations run parallel to the reporting requirements. Institutions must maintain records relating to blocked transactions and blocked accounts for five years from the date of the transaction, under the applicable OFAC regulations. Those records must be available for inspection by OFAC and, in criminal matters, by the Department of Justice. In our experience, firms that have invested in clear record structures at the point of blocking are better placed to respond to both routine OFAC inquiries and enforcement investigation requests.
The interaction with anti-money-laundering record-keeping requirements should also be noted. An institution holding blocked property will typically have parallel obligations under the Bank Secrecy Act and, where relevant, Suspicious Activity Report filing obligations. The two regimes do not cancel each other out: compliance with AML rules does not satisfy OFAC reporting requirements, and vice versa. Both sets of records must be maintained separately and to their respective standards.
What licensing routes are available for dealing with frozen funds?
A specific licence (a case-by-case authorisation from OFAC to conduct an otherwise prohibited transaction) is the primary route for an institution or account holder seeking to engage in dealings with blocked property that are not covered by an existing general licence. Specific licences are granted on the facts of the individual case, after a review of the application and any supporting documentation OFAC requires. There is no guaranteed outcome and no fixed timeline, although OFAC publishes indicative processing periods for different categories of licence request.
A general licence (a standing authorisation that permits a defined category of transactions without a separate application) may cover certain dealings with blocked accounts. Common categories include wind-down transactions, payment of legal fees and basic living expenses, and maintenance transactions necessary to preserve the value of blocked property. Whether a general licence applies requires careful reading of both the licence terms and the specific programme regulations: general licences are programme-specific and can differ materially between, for example, the Russian and North Korean programmes.
The application process for a specific licence requires the applicant to identify the relevant programme, describe the proposed transaction in detail, explain the licensing basis, and – where the beneficial owner of the blocked property is the applicant – provide supporting evidence of entitlement. Where an account-holding institution is applying on behalf of an account holder, questions of standing and authorisation arise that should be addressed at the outset.
For cross-border groups, a licensing decision from OFAC does not automatically resolve the position under OFSI or the EU. Both UK and EU licences must be obtained separately, from OFSI and from the relevant competent authority of the EU member state respectively. The tests and the documentation requirements differ. We address the OFSI licensing regime in our OFSI frozen-account briefing, and our BIS/EAR service covers the export-control licensing dimension for goods and technology subject to a dual-use or military classification: see our frozen-account management BIS/EAR service page.
If a filing has been refused or a pending licence application has been outstanding without response, an early review of the factual and procedural position can preserve options that narrow over time. Contact Calder & Vance at info@caldervance.com to discuss.
How is frozen-account management enforced under OFAC?
OFAC enforces the blocking obligations through a civil penalty regime and, for the most serious cases, refers matters to the Department of Justice for criminal prosecution. The civil penalty base under IEEPA is the greater of a statutory maximum per violation or twice the value of the transaction at issue. These figures are adjusted periodically for inflation. The resulting exposure for a financial institution that fails to block a large balance, or that deals in blocked property without a licence, can be substantial.
Enforcement cases frequently arise from failures at the point of initial detection: a screening system that does not capture an ownership chain, a name-matching algorithm that misses a transliteration variant, or a manual review queue that clears a match as a false positive without adequate documentation of the analysis. In our practice, we advise institutions that the quality of the documented analysis at the point of the initial review is as important as the outcome of that review: a well-documented false-positive determination provides a strong foundation for any future enforcement inquiry; an undocumented clearance does not.
OFAC's enforcement guidelines place significant weight on whether a violation was voluntarily self-disclosed. A VSD (voluntary self-disclosure to OFAC of an apparent violation) is treated as a mitigating factor and, in cases where all other factors weigh in favour of a reduced response, can result in a substantially reduced penalty or a no-action outcome. The mechanics of a VSD – when to file, what to include, and what disclosures preserve privilege – are matters of experienced judgment. Filing too early, before the scope of the apparent violation is known, can be as problematic as filing late.
Egregious violations – defined under OFAC's guidelines as those involving wilful or reckless conduct, senior-management knowledge, or a pattern of misconduct – attract penalties at the higher end of the applicable range and are more likely to be referred for criminal action. For an institution that has discovered a potential failure in its blocking obligations, the first step is scoping: understanding the full population of affected accounts and transactions before making any disclosure or remediation decision.
A myth that circulates in compliance teams is that small-value blocking failures are below OFAC's enforcement threshold and can be managed internally without disclosure. That is not consistently the case. OFAC's enforcement record includes settlements arising from relatively low-value transactions where the egregious factors or the pattern of conduct outweighed the dollar amount of the violation. The value of the transaction is one factor, not the determinative one.
What are the key risk flags for institutions managing blocked accounts?
Several patterns in our cross-border practice recur as risk flags for institutions holding or managing blocked accounts. Identifying them at the point of intake, rather than after an enforcement inquiry has begun, is the purpose of a well-designed frozen-account management protocol.
The first risk flag is an incomplete ownership chain at the point of initial blocking. Where an account holder is a legal entity rather than a natural person, the institution must map beneficial ownership to the point at which no listed person appears above the 50 percent threshold. Stopping at the account holder's direct shareholders is not sufficient if those shareholders are themselves entities.
The second risk flag is dealing with the account holder in ways that do not appear on their face to be prohibited. Correspondence about the account, provision of account statements, or acceptance of instructions from a purported attorney or agent may constitute services to a blocked person. Each interaction with the account holder after the blocking order should be reviewed for licensing status before it occurs.
The third risk flag is the passage of time. A blocked account does not resolve itself. Funds accumulate if they bear interest; fees accrue against the balance; the account holder may send instructions or initiate legal proceedings. Institutions that treat a frozen account as a file that can be set aside until an authorisation arrives tend to accumulate undisclosed dealing that complicates any eventual licensing or remediation process.
The fourth risk flag – particularly relevant for institutions with correspondent banking relationships – is the existence of a blocked account at a respondent institution. Where a respondent bank is the account holder, the correspondent may have secondary exposure if it continues to process transactions for the respondent without investigating whether the respondent's own blocking obligations have been discharged.
In a recent matter, a financial-services business reviewing a portfolio of dormant accounts identified a small number that had been frozen years earlier under a predecessor compliance regime and had not been reported to OFAC within the required window. We scoped the apparent violations, assessed the egregious-factors analysis, and prepared a voluntary self-disclosure that addressed the reporting failures in their full context. The matter was resolved through the regulatory process without referral for criminal consideration. No outcome of that kind is guaranteed; the facts of each matter determine the result.
