Sanctions lists and list institutions

Sanctions lists are the public designation instruments maintained by separate legal authorities, principally OFAC in the United States, the UK Sanctions List under the Sanctions and Anti-Money Laundering Act 2018, European Union restrictive measures, and United Nations Security Council sanctions regimes. This guide treats those lists as institutions: who maintains each list, on what legal basis, with what jurisdictional reach, and with what listing and delisting architecture. It sits beside the sanctions and AML trade finance hub and the shorter comparison in OFAC, EU, UK and UN Sanctions Lists Compared.

Bank export finance, project finance and commercial real estate desks encounter sanctions lists as legal source material that can affect capacity to contract, receive funds, hold assets or participate in a financing. The common label of sanctions list can obscure different legal effects. A designation on one list is not automatically the same legal act as a designation on another, even where names overlap across public lists. Sanctions screening is the institutional control that maps counterparties and related parties to those sources; it is not a single shared global register.

Sanctions lists maintained by OFAC

The Office of Foreign Assets Control is a component of the Office of Terrorism and Financial Intelligence at the United States Department of the Treasury. OFAC administers and enforces economic sanctions based on United States foreign policy and national security goals against targeted foreign countries and regimes, terrorists, international narcotics traffickers, persons engaged in activities related to the proliferation of weapons of mass destruction, and other threats described in its mandate.

OFAC's responsibilities include promulgating implementing regulations; identifying and designating individuals and entities subject to OFAC-administered sanctions; maintaining OFAC's sanctions lists; issuing licences to authorise certain otherwise-prohibited activity; civil enforcement; and providing compliance guidance. Legal authorities include United States statutes such as the Trading With the Enemy Act, executive orders issued pursuant to the International Emergency Economic Powers Act, implementing regulations in 31 CFR Chapter V, and laws implementing United Nations Security Council resolutions.

OFAC's principal list is the Specially Designated Nationals and Blocked Persons List, commonly called the SDN List. OFAC states that SDNs include individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries, and individuals, groups and entities such as terrorists and narcotics traffickers designated under programmes that are not country-specific. Their assets are blocked and United States persons are generally prohibited from dealing with them. The SDN List is frequently updated without a predetermined timetable. Changes for the current calendar year are available in the SDN List PDF file, and cumulative historical changes are archived.

OFAC also administers non-SDN sanctions lists. The Foreign Sanctions Evaders List and the Sectoral Sanctions Identifications List are examples. United States persons are not required to block the property of persons on those FSE and SSI lists unless the targets are also on the SDN List, but other prohibitions and investment restrictions apply. OFAC's Consolidated Sanctions List and Sanctions List Search tools provide access across SDN and non-SDN lists. The Bureau of Industry and Security of the United States Department of Commerce maintains separate Denied Persons and Entity lists for export-control purposes; OFAC states that the foreign-policy objectives and legal requirements of OFAC and BIS programmes differ and preclude a combined list.

OFAC describes list-based blocking sanctions, list-based non-blocking sanctions, sector-based sanctions, government blocking, jurisdiction-based sanctions and secondary sanctions as programme types. Blocking imposes an across-the-board prohibition against transfers or dealings by United States persons with regard to the blocked person's property and interests in property. United States persons in possession or control of such property must block it and report that action to OFAC. Some prohibited transactions without a blockable interest are rejected rather than blocked and must still be reported.

Generally, all United States persons must comply with OFAC sanctions: United States citizens and permanent residents wherever located, individuals and entities within the United States, and United States-incorporated entities and their foreign branches. Transactions within or transiting the United States must also comply. Non-United States persons can be subject to certain prohibitions, including causing or conspiring to cause United States persons to violate sanctions and engaging in conduct that evades sanctions. Certain programmes also reach non-United States subsidiaries of United States persons and non-United States persons reexporting United States-origin goods, technology or services.

Delisting from an OFAC list proceeds through administrative reconsideration under 31 CFR section 501.807. Petitioners may use OFAC's Reconsideration Portal. OFAC endeavours to perform initial review of portal submissions within seven to ten business days and then conducts a reinvestigation that can be lengthy. Petitions may be granted or denied. If granted, the person or property is removed from the relevant list and a Federal Register notice is published. If denied, a further petition may be filed with new arguments or evidence. The administrative reconsideration process is for persons who appear on OFAC lists or are otherwise sanctioned; name-match false positives are directed to OFAC's Compliance Hotline rather than to delisting.

UK Sanctions List, FCDO and OFSI

United Kingdom sanctions are restrictive measures that can be put in place to fulfil purposes including complying with United Nations and other international obligations, supporting foreign policy and national security objectives, maintaining international peace and security, and preventing terrorism. Types of UK sanctions measures include financial sanctions including asset freezes; director disqualification sanctions; trade sanctions including arms embargoes and other trade restrictions; aircraft and shipping sanctions known as transport sanctions; and immigration sanctions known as travel bans.

As of 28 January 2026, the Foreign, Commonwealth and Development Office maintains the UK Sanctions List under the Sanctions and Anti-Money Laundering Act 2018. The UK Sanctions List names individuals, businesses, organisations and ships that are the targets of certain sanctions measures such as asset freezes and transport sanctions. The OFSI Consolidated List of Asset Freeze Targets closed on 28 January 2026. The UK Sanctions List is now the only source for all UK sanctions designations. OFSI implements financial sanctions against those listed on the UK Sanctions List.

OFSI is an office within His Majesty's Treasury. It was established in March 2016 with functions previously transferred from the Bank of England, which had acted as the Treasury's agent in administering financial sanctions. OFSI implements financial sanctions and certain trade sanctions based on UK foreign policy set by FCDO.

OFSI is responsible for promulgating sanctions legislation; identifying and designating individuals under the domestic counter-terrorism sanctions regime; implementing financial sanctions against those on the UK Sanctions List; issuing licences; civil enforcement; and guidance. HM Treasury leads on designations under the UK's domestic counter-terrorism sanctions regime. Legal authorities include the Sanctions and Anti-Money Laundering Act 2018, the Counter-Terrorism Act 2008, secondary legislation such as regime-specific regulations, and laws implementing United Nations Security Council resolutions.

UK financial sanctions may require UK persons to freeze designated persons' funds and economic resources. Generally all activity and dealings involving a designated person are prohibited, as is making economic resources available to or for the benefit of the designated person. Funds include financial assets and benefits such as cash, deposits, securities, debt obligations and cryptoassets. Economic resources are tangible or intangible assets that are not funds but can be used to obtain funds, goods or services. UK sanctions regimes also employ sectoral sanctions and directions requiring specific actions.

Jurisdictionally, UK sanctions regulations apply to any individual, business or organisation located or undertaking activities anywhere in the UK including the territorial sea; any business or organisation incorporated or constituted under the law of any part of the UK; and any UK individual, business or organisation outside the UK. It is government policy for UK sanctions measures to be given effect in the British Overseas Territories and Crown Dependencies. Non-UK persons are subject to certain prohibitions where activity has a UK nexus.

Implementation is split across institutions. FCDO is responsible for high-level policy and decisions about sanctions designations and ship specifications. OFSI handles financial sanctions civil enforcement and licensing, including the Oil Price Cap on Russian oil. The Office of Trade Sanctions Implementation handles certain trade-sanctions licensing and civil enforcement for standalone services and for some movements that do not cross the UK border. HMRC handles criminal enforcement of trade sanctions and border enforcement. The Department for Transport implements transport sanctions. The Home Office implements immigration sanctions. The National Crime Agency investigates and prosecutes criminal breaches of financial and transport sanctions.

Exceptions apply automatically within defined circumstances in each regime. Licences are written permissions for actions that would otherwise breach sanctions. Sector-specific guidance exists for financial services, legal services, charities, high-value dealers, maritime shipping, importers and exporters, cryptoassets and other sectors. Relevant firms and relevant institutions under UK sanctions regulations carry additional reporting duties defined in regime-specific legislation.

EU restrictive measures as sanctions lists institutions

European Union sanctions, also called restrictive measures, are a Common Foreign and Security Policy tool through which the EU can intervene to prevent conflict or respond to emerging or current crises. The EU implements all sanctions adopted by the United Nations Security Council. UN sanctions are automatically transposed into EU law. The EU occasionally applies additional measures to complement and reinforce United Nations sanctions. The EU also adopts autonomous sanctions to fight terrorism financing, defend human rights and democratic institutions, or prevent the proliferation of chemical weapons or weapons of mass destruction.

Under Article 29 of the Treaty on European Union, the Council of the EU takes decisions to adopt, renew or lift sanctions regimes based on proposals by the High Representative of the Union for Foreign Affairs and Security Policy or by the Member States. Decisions relating to sanctions are taken by the Council by consensus. If the Council Decision includes measures with economic and/or financial implications, the measures need to be implemented in a Council Regulation jointly presented by the High Representative and the European Commission on the basis of Article 215 of the Treaty on the Functioning of the European Union. The CFSP Council Decision and the Council Regulation are adopted simultaneously.

Implementation and enforcement of EU sanctions are the responsibility of the EU Member States. The Commission monitors that regulations adopted under Article 215 TFEU are implemented and enforced by the Member States. The Commission also publishes guidance and contact channels for specific regimes, including dedicated material on sanctions adopted following Russia's military aggression against Ukraine, and maintains an EU sanctions helpdesk for compliance queries.

For bank desks, the institutional point is dual. First, EU listings sit inside the EU legal order rather than inside a single national treasury list. Second, some EU measures correspond to UN obligations while others are autonomous. A name that appears in an EU annex is therefore read against the Council Decision and, where economic or financial measures apply, against the related regulation, not against OFAC or UK list logic alone.

United Nations Security Council sanctions regimes

The Security Council can take action to maintain or restore international peace and security under Chapter VII of the United Nations Charter. Sanctions measures under Article 41 encompass enforcement options that do not involve the use of armed force. Since 1966, the Security Council has established 31 sanctions regimes across a range of country and thematic situations, including Southern Rhodesia, South Africa, the Former Yugoslavia, Haiti, Angola, Liberia, Eritrea/Ethiopia, Rwanda, Sierra Leone, Côte d'Ivoire, Iran, Somalia/Eritrea, ISIL (Da'esh) and Al-Qaida, Iraq, the Democratic Republic of the Congo, Sudan, Lebanon, the Democratic People's Republic of Korea, Libya, the Taliban, Guinea-Bissau, the Central African Republic, Yemen, South Sudan and Mali.

Security Council sanctions have taken forms ranging from comprehensive economic and trade sanctions to targeted measures such as arms embargoes, travel bans, and financial or commodity restrictions. Goals have included supporting peaceful transitions, deterring non-constitutional changes, constraining terrorism, protecting human rights and promoting non-proliferation. As described by the United Nations, there are 15 ongoing sanctions regimes focused on supporting political settlement of conflicts, nuclear non-proliferation and counter-terrorism. Each regime is administered by a sanctions committee chaired by a non-permanent member of the Security Council. Ten monitoring groups, teams and panels support the work of 11 of the 15 sanctions committees.

Fair and clear procedures for imposition and lifting of measures are part of the institutional design. The establishment of a focal point for de-listing and the Office of the Ombudsperson to the ISIL (Da'esh) and Al-Qaida Sanctions Committee are examples. For that list, delisting requests proceed through the Ombudsperson mechanism rather than through a national treasury reconsideration portal. National and EU systems then give effect to Security Council measures through their own domestic or regional instruments.

UN lists are therefore source lists for obligations that other legal systems implement. They are not substitutes for OFAC, UK or EU autonomous designations. Desks that see only a UN listing still need to identify which domestic or regional implementing measure applies to the financing parties and the payment path.

How the four sanctions lists relate for bank desks

The four regimes relate as separate legal sources that may all be relevant to a counterparty, sponsor, borrower, guarantor, vessel, aircraft or other transaction party.

Maintainer and list:

• OFAC maintains the SDN List and non-SDN lists under United States sanctions authorities.
• FCDO maintains the UK Sanctions List; OFSI implements financial sanctions against listed persons.
• The Council of the EU adopts CFSP decisions and, where needed, Article 215 TFEU regulations; Member States implement and enforce.
• UN Security Council committees administer UN regimes; states and the EU implement those obligations.

Legal effect vocabulary differs. OFAC blocking and rejection are United States-law concepts. UK asset freezes and making-available prohibitions are UK-law concepts. EU restrictive measures combine political decisions with regulations where economic and financial measures apply. UN measures under Article 41 are international obligations given domestic effect elsewhere.

Jurisdiction differs. United States persons, UK persons and EU operators are not identical populations. Secondary sanctions and UK-nexus concepts extend reach beyond pure nationality or incorporation tests in defined cases. A financing that clears one jurisdictional filter can still engage another if parties, payment currency, correspondent banks or collateral sit in a second legal order.

Ownership and control overlays sit beside the lists themselves. OFAC's 50 percent ownership rule and related ownership guidance, UK ownership and control tests in regime regulations, and EU ownership and control language in regulations determine when unlisted entities are treated as caught because of ownership or control by listed persons. Those rules are institutional doctrines, not list entries.

Beneficial ownership identification through ultimate beneficial owner (UBO), beneficial ownership, PSC register concepts and legal entity identifiers (LEI) supports customer due diligence, know your customer (KYC) and know your business (KYB) workstreams that feed sanctions screening. Adverse media screening is adjacent reputational and risk intelligence, not a substitute for list-based legal prohibitions. FATF standards on targeted financial sanctions and preventive measures set the international AML and counter-terrorist financing architecture within which national screening obligations sit.

Licensing and exceptions are regime-specific. OFAC general and specific licences, UK exceptions and licences, and EU derogations and authorisations do not automatically recognise one another. A licence from one authority does not authorise conduct prohibited by another authority.

Boundaries and credit-desk classification

This guide classifies sanctions lists as public-law institutions. It does not teach transaction monitoring architecture, register-mining workflows or deal-signal discovery. Those operational products sit outside this institutional primer.

For credit committees, the classification checklist is source-based. Identify which list or implementing instrument is engaged. Identify the maintainer and the enforcing authority. Identify whether the measure is blocking, freezing, sectoral, directional or jurisdiction-based. Identify whether the measure is UN-derived, autonomous, or both. Identify ownership and control overlays that may pull in unlisted entities. Identify whether a licence or exception exists in the relevant legal order. Identify which financing parties are United States persons, UK persons, EU operators or otherwise within nexus tests.

Export finance overlays remain separate. UKEF states that a Buyer Credit Facility transaction may not be supported if sanctions are imposed on the country of the overseas buyer. That national eligibility filter sits beside bank sanctions screening rather than replacing it. Project finance and CRE files apply the same list institutions to sponsors, offtakers, contractors, tenants, vessels and payment intermediaries.
