Office of Foreign Assets Control
Also known as:
Simply put
The Office of Foreign Assets Control (OFAC) is a U.S. government agency within the Department of the Treasury that administers and enforces economic and trade sanctions against targeted countries, entities, and individuals. It uses tools such as blocking (freezing) assets and restricting trade to advance U.S. foreign policy and national security goals. OFAC is the successor to the Office of Foreign Funds Control, which was established around the start of World War II.
Formal definition
The Office of Foreign Assets Control (OFAC) is the office of the U.S. Department of the Treasury responsible for administering and enforcing economic sanctions programs against targeted jurisdictions, entities, and persons. These programs may be comprehensive or selective in scope and rely on measures including the blocking of property and interests in property and trade restrictions. OFAC guidance includes interpretive rules such as the 50 Percent Rule, under which the property and interests in property of entities owned, directly or indirectly, 50 percent or more in the aggregate by one or more blocked persons are themselves treated as blocked. As a matter of scope, OFAC's authorities derive from U.S. law; obligations and prohibitions under specific OFAC programs vary by program and should be confirmed against the applicable regulations and the current Specially Designated Nationals and Blocked Persons List and other OFAC lists.
Why it matters
OFAC administers and enforces U.S. economic and trade sanctions, which makes it one of the most consequential authorities that compliance functions must contend with, including firms outside the United States whose activities touch the U.S. financial system, U.S. persons, or U.S.-origin goods and services. Sanctions programs administered by OFAC may be comprehensive, targeting entire jurisdictions, or selective, targeting specific entities and individuals. Because these programs rely on measures such as blocking (freezing) property and interests in property and imposing trade restrictions, an obliged entity that processes a prohibited transaction or deals with a blocked party may face enforcement exposure. Sanctions compliance is a distinct discipline from anti-money laundering controls, and screening against OFAC lists should not be conflated with PEP screening or with customer due diligence more broadly.
Who it's relevant to
Sanctions compliance officers
Professionals responsible for designing and operating sanctions screening programs rely on OFAC designations and interpretive guidance to calibrate their controls. The 50 Percent Rule in particular requires attention to ownership structures, because an unnamed entity may nonetheless be treated as blocked based on its ownership by one or more blocked persons. These are measures to detect and manage sanctions exposure rather than guarantees against violations.
Financial institutions and other obliged entities
Banks, payment providers, and other firms whose activities involve U.S. persons, the U.S. financial system, or U.S.-origin goods and services may fall within the reach of OFAC-administered programs. Such firms generally screen customers and transactions against the SDN List and other OFAC lists and apply blocking or rejection where required by the applicable program. Whether and how a particular program applies depends on the facts and should be confirmed against the relevant regulations.
Trade finance and export compliance teams
Because OFAC programs can include trade restrictions in addition to asset blocking, teams handling cross-border trade, letters of credit, and goods movements need to assess whether targeted jurisdictions, entities, or individuals are involved. The comprehensive-versus-selective distinction is material here, as the permitted scope of dealings differs significantly between program types.
Legal, risk, and investigations professionals
Counsel and risk professionals advising on sanctions matters draw on OFAC's authorities, program scope, and published lists to assess exposure and respond to potential apparent violations. A screening match or a blocked transaction is an operational and compliance event to be assessed on its facts; it does not by itself establish criminal wrongdoing.
Inside OFAC
US Treasury Agency
OFAC is an agency within the US Department of the Treasury responsible for administering and enforcing economic and trade sanctions programs based on US foreign policy and national security goals.
Specially Designated Nationals and Blocked Persons List (SDN List)
OFAC maintains the SDN List, which identifies individuals, entities, vessels, and aircraft whose assets are blocked and with whom US persons are generally prohibited from dealing. It is distinct from PEP lists and from other watchlists, and screening against it is a sanctions control rather than a broader due diligence measure.
Sanctions Programs
OFAC administers both comprehensive programs (targeting entire jurisdictions or regimes) and list-based or targeted programs (focused on specific persons or activities). The scope and prohibited activities differ by program, so obligations depend on the specific program at issue.
Blocking and Rejecting Requirements
Depending on the applicable program, US persons may be required to block (freeze) property in which a sanctioned party has an interest, or to reject certain transactions, and to report such actions to OFAC. The specific treatment varies by program and transaction type.
50 Percent Rule (Ownership Aggregation)
OFAC guidance generally treats an entity as blocked if it is owned, directly or indirectly, 50 percent or more in the aggregate by one or more blocked persons, even if that entity is not itself named on the SDN List. This makes beneficial ownership analysis relevant to sanctions screening.
Licenses (General and Specific)
OFAC may authorize otherwise-prohibited activity through general licenses (broadly available authorizations) or specific licenses (case-by-case authorizations applied for by a party). Practitioners should confirm the terms and conditions of any applicable license.
Scope of Application (US Nexus)
OFAC obligations generally apply to US persons and, depending on the program, to certain transactions with a US nexus. The precise reach varies by program, and exact jurisdictional scope should be confirmed against the applicable regulation.
Common questions
Answers to the questions practitioners most commonly ask about OFAC.
Does OFAC only administer sanctions against countries or governments?
No. While OFAC does administer comprehensive country- or territory-based programs, it also administers list-based (targeted) sanctions against specific individuals, entities, vessels, and other parties regardless of their nationality or location. Parties designated on the Specially Designated Nationals and Blocked Persons (SDN) List, for example, may be targeted based on conduct, such as involvement in terrorism, narcotics trafficking, or proliferation, rather than solely on their country of residence. Treating OFAC sanctions as purely geographic overlooks a substantial portion of the programs it enforces.
Is a positive screening match against an OFAC list proof that a customer has committed wrongdoing?
No. A screening alert or apparent name match is an operational signal that a transaction or party may correspond to a sanctioned target; it is not a finding of criminal conduct or a legal determination. Many alerts are false positives arising from name similarities, incomplete data, or common names, and require analyst review and adjudication before any action is taken. A confirmed true match triggers compliance obligations, such as blocking or rejecting a transaction and reporting to OFAC, but this reflects the strict-liability nature of many sanctions requirements rather than an adjudication of the customer's guilt. Sanctions compliance conclusions should be kept distinct from criminal-law determinations.
Who is subject to OFAC sanctions requirements?
OFAC's jurisdiction generally extends to all U.S. persons, which typically includes U.S. citizens and permanent residents wherever located, entities organized under U.S. law and their foreign branches, and persons physically present in the United States. Certain programs also reach transactions with a U.S. nexus, such as those involving U.S.-origin goods, U.S. dollar clearing, or U.S. financial institutions, and some programs assert additional reach through secondary sanctions that can affect non-U.S. persons. Because the precise scope varies by program, obliged parties should confirm applicability against the specific regulation and any relevant OFAC guidance.
How should an institution respond when it identifies a confirmed true match to an SDN or blocked party?
Generally, when a party or transaction is confirmed to involve blocked persons or blockable property, U.S. persons are typically required to block (freeze) the property or reject the transaction, depending on the applicable program, and to file the required report with OFAC within the timeframe specified by the relevant regulation. The distinction between blocking and rejecting depends on the program and the nature of the transaction. Institutions should follow their sanctions policies and escalate to their compliance function, and confirm the specific reporting obligations and deadlines against the applicable OFAC rules, as these can differ by program.
What role does OFAC's guidance on a risk-based compliance program play in implementation?
OFAC has published a framework describing components commonly associated with an effective sanctions compliance program, which typically emphasizes management commitment, risk assessment, internal controls, testing and auditing, and training. These are described as measures to help detect, deter, and manage sanctions exposure, not guarantees against violations. Because many sanctions prohibitions operate on a strict-liability basis, a well-designed program can help mitigate risk and may be considered in the context of enforcement, but it does not eliminate the possibility of an apparent violation. Institutions should tailor controls to their specific risk profile and confirm expectations against current OFAC guidance.
How do OFAC sanctions screening obligations differ from AML customer due diligence?
Sanctions screening and AML customer due diligence (CDD) serve distinct purposes and derive from different authorities. Sanctions screening compares parties and transactions against OFAC lists and program criteria to identify prohibited dealings, and often applies on a strict-liability basis. CDD, by contrast, is part of the AML framework and focuses on understanding a customer's identity, ownership, and expected activity to assess and manage money laundering and related risks. They may rely on overlapping data and systems but should not be conflated: clearing a sanctions screen does not satisfy CDD obligations, and completing CDD does not discharge screening requirements. The precise obligations for each should be confirmed against the applicable regulations.
Common misconceptions
An OFAC screening match confirms that a customer is a criminal or sanctions evader.
A screening alert indicates a potential match against a list and requires investigation and disposition; it does not by itself establish wrongdoing. Many alerts are false positives arising from name similarity, and a true match is a compliance and legal issue distinct from any finding of criminal conduct.
Sanctions screening and PEP screening are the same control.
Sanctions screening against OFAC lists addresses prohibited dealings with designated parties, whereas PEP screening is a due diligence measure to assess heightened risk associated with politically exposed persons. They serve different purposes, rely on different sources, and produce different obligations.
Only entities explicitly named on the SDN List need to be avoided.
Under OFAC's 50 percent rule guidance, entities owned 50 percent or more in the aggregate by blocked persons may themselves be treated as blocked even without being individually listed, so beneficial ownership must be considered rather than relying solely on named-party matches.
Best practices
Confirm which specific OFAC program applies to a given customer, counterparty, or transaction, since comprehensive and targeted programs impose different prohibitions and obligations.
Investigate and document the disposition of every screening alert before taking action, treating a match as a potential issue to be resolved rather than as proof of wrongdoing.
Incorporate beneficial ownership analysis into sanctions screening to account for the 50 percent aggregate ownership rule, rather than relying only on named-party matches to the SDN List.
Verify current list content and program details directly against OFAC's published resources, as designations and program terms change over time.
Where required by the applicable program, block or reject transactions and file the corresponding reports to OFAC within the prescribed requirements, confirming exact obligations against the current rules.
Check whether a general or specific license authorizes otherwise-prohibited activity, and ensure any reliance on a license stays within its stated terms and conditions.
