“Blocked” vs. “Frozen” Assets: What OFAC’s Terminology Actually Means
Under OFAC’s regulations, “blocked” is the formal legal term (see 31 C.F.R. § 501.201, Blocking of Assets); “frozen” is the informal term the public and media use for the same thing. This page covers how blocking works as a regulatory mechanism — including what financial institutions are legally required to do. If you’re an individual or business whose own funds were blocked and want to know what to do next, see our guide on frozen assets.
What Counts as a “Blocked Asset” Under OFAC Rules
A blocked person is an individual or entity that OFAC has itself designated — appearing on the SDN List or a comparable list. Blocked assets are the property or funds that must be blocked because a blocked person has an interest in them — and that property can belong to someone who is not themselves a blocked person. You can hold blocked assets without being a blocked person yourself.
Blocking does not transfer ownership. The original owner retains legal title; what’s suspended is the ability to exercise that ownership — transfer, withdraw, or use the funds. That’s why blocked funds are placed in an interest-bearing account (per 31 C.F.R. § 501.603) rather than confiscated: the government is holding the asset, not taking it.
There is no automatic override for hardship situations. Even for a medical emergency or a tuition payment, releasing blocked funds requires a specific OFAC license — a case-by-case authorization, not a standing exception.
Can Subpoenas, Investigations, or Violations by OFAC Affect a Person’s Immigration Status?
This depends on the circumstances of the case, notes our lawyer. If the investigation is related to involvement in illegal activities, providing support or financial resources to sanctioned individuals or organizations, or narcotics trafficking, it may affect a person’s immigration status. Each case requires an individual analysis of all the facts.
Subpoenas or investigations by OFAC can seriously affect the ability to obtain a visa, green card, or citizenship. For example, violations of sanctions legislation may lead to the following consequences:
- Refusal to issue a visa. If a person is suspected of circumventing sanctions, financing prohibited activities, or managing blocked accounts, the authorities may deny entry to the USA.
- Restriction on obtaining a green card. Participation in schemes related to money laundering or supporting individuals from the SDN list makes a person ineligible for permanent residency.
- Deprivation of benefits during naturalization. In the case of active investigations or proven violations of OFAC sanctions, the naturalization process may be suspended or completely rejected.
- Risk of deportation. If a person is already residing in the USA, but their actions are related to violations of sanctions programs or managing blocked accounts, this may serve as grounds for deportation.
OFAC pays attention to entities involved in any suspicions related to sanctions evasion, financial fraud, narcotics trafficking, or support of prohibited organizations.
To protect your rights and minimize risk — especially if your matter touches both sanctions compliance and immigration status — consult a lawyer with experience in both areas. They can assess how an OFAC investigation may affect your bank accounts and advise on the right defense strategy.
A Financial Institution’s Blocking Obligations
When a financial institution identifies a match against the SDN List, it must:
- Block, not reject, the transaction — funds are placed in a blocked, interest-bearing account, not returned to the sender.
- Report the block to OFAC within 10 business days of the blocking action.
- File an Annual Report of Blocked Property each September 30 for as long as the assets remain blocked.
- Retain records for at least 5 years under 31 C.F.R. § 501.601–602.
- Not disclose the block to the customer beyond what’s legally required — this is why account holders often only learn about a freeze after receiving a subpoena or seeing funds disappear from a statement.
Institutions submit blocking reports and the Annual Report of Blocked Property through OFAC’s Reporting System (OFAC RRS), not by mail or generic correspondence — using the wrong channel is itself treated as a compliance failure.
Therefore, it is extremely important to comply with the law, do due diligence, keep bank accounts, check counterparties, and respond promptly to any suspicions. Consulting with experienced lawyers and financial institution is a reliable way to do due diligence and protect yourself from the risk of legal issues.
Frequently Asked Questions
What is a blocked asset under OFAC rules?
A blocked asset is any property or funds in which a blocked person — someone appearing on the SDN List or a comparable OFAC list — holds an interest. The original owner keeps legal title, but until OFAC issues a specific license, they cannot transfer, withdraw, access, or otherwise deal with the asset in any way. A person or company can end up holding a blocked asset without being a blocked person themselves, simply because a designated party has an interest in the same funds or property.
What is a blocked account?
A blocked account is a bank or financial account where withdrawals, transfers, and other transactions are frozen because the account holder — or a related party — is designated on OFAC’s SDN List or otherwise subject to sanctions. The funds are not seized or confiscated; they remain the property of the account holder but sit inaccessible until OFAC grants a license or the underlying sanction is lifted.
True or false: when a blocked account is established to hold an entity’s frozen assets, the funds must be placed in an interest-bearing account?
True. Under OFAC regulations, once frozen assets are placed into a blocked account, the holding institution is generally required to deposit the funds into an interest-bearing account, so the value is preserved for the owner while the blockage remains in effect.
Does a country or entity whose property is blocked by OFAC still own the assets?
Yes. Blocking does not transfer ownership. A country, company, or individual whose property is blocked by OFAC retains legal title to the assets but cannot use, transfer, or dispose of them without OFAC’s specific authorization — typically in the form of a specific or general license.
What does “blocked funds” or “blocked property” mean under OFAC rules?
Blocked funds and blocked property refer to any money, securities, real estate, or other assets in which a sanctioned person or entity has an interest, and which a U.S. person or financial institution must freeze immediately upon identifying the connection. The term covers bank deposits as well as physical and intangible property.
What is the difference between “blocked persons” and “blocked assets”?
Blocked persons are the individuals, companies, or organizations designated by OFAC — most commonly through the SDN List — with whom U.S. persons are prohibited from transacting. Blocked assets are the actual funds or property connected to those persons that must be frozen as a result of the designation.
What must a financial institution do if it identifies a match to an entity on the OFAC SDN list?
If an institution identifies a match to a party on the SDN List, it must block or freeze the transaction immediately and report it to OFAC within the required timeframe — generally 10 business days. The institution cannot simply cancel or return the funds; the assets must be placed into a blocked account pending further action.
How long must a financial institution retain records of blocked property?
Records related to blocked property must generally be retained for at least five years from the date the property is unblocked, in accordance with OFAC recordkeeping requirements. Institutions should keep full documentation of the blocking, any communications with OFAC, and the eventual resolution.
Can a blocked account be overridden for a medical emergency or tuition payment?
Not without authorization. An account block cannot be overridden simply because funds are needed for a medical emergency, college tuition, or a change in marital status. Any release of blocked funds — regardless of the reason — requires a specific license from OFAC.
If an account is blocked, are transfers still allowed even though withdrawals are prohibited?
No. A blocked account restricts both withdrawals and transfers. Once an account is frozen under OFAC sanctions, no movement of the funds is permitted in any form without OFAC’s specific authorization.
What activities or relationships are considered prohibited under OFAC rules?
Prohibited activity generally includes any dealings with individuals or entities designated by OFAC, the UN Security Council, or other sanctioning bodies, as well as accounts where the holder’s identity cannot be verified or required documentation cannot be obtained due to the customer’s non-cooperation.
Why do asset freezes often cause long delays in accessing funds?
Asset access delays happen because OFAC reviews each blocked-funds case individually, and there is no fixed timeline for a decision. Between preparing documentation, submitting the application, and awaiting OFAC’s response, clients can face delays ranging from several weeks to over a year, depending on the complexity of the case.
