    What are sanctions?

    Sanctions are restrictive measures imposed by governments and international bodies to pursue foreign-policy and security aims. For regulated firms they are the hardest of all financial-crime rules: breaches are usually strict liability, lists change without warning, and one missed match can cost market access. This guide covers the definition, the main types, who imposes them, and what compliance actually requires.

    Sanctions definition

    A sanction is a legally binding restriction on dealing with a designated country, sector, entity, vessel or person. Financial sanctions typically require firms to freeze assets, reject or block payments, refuse onboarding, and report the exposure to the competent authority. Unlike much of AML law, sanctions leave no risk-based discretion: a match is either a prohibited party or it is not.

    Types of sanctions

    Targeted (smart) sanctions

    Asset freezes and prohibitions aimed at named individuals, entities, vessels or aircraft — for example OFAC's SDN list or the UK and EU consolidated lists.

    Sectoral sanctions

    Restrictions on specific economic sectors — finance, energy, defence, technology — rather than whole economies, often limiting debt, equity or dual-use exports.

    Comprehensive / country programmes

    Broad prohibitions on nearly all dealings with a jurisdiction, requiring licences for even humanitarian transactions.

    Secondary sanctions

    Measures that reach non-US persons who transact with sanctioned parties, exposing firms outside the imposing country to consequences.

    Who imposes them

    United Nations

    Security Council resolutions binding on member states, implemented through national or EU law.

    United States — OFAC

    Administers US sanctions programmes and maintains the Specially Designated Nationals (SDN) list; penalties are strict liability.

    European Union

    Council regulations directly applicable in all Member States, published in the EU consolidated list.

    United Kingdom — OFSI

    Maintains the UK consolidated list and enforces financial sanctions breaches under post-Brexit powers.

    Other national regimes

    Switzerland, Canada, Australia, Japan and others run their own lists that frequently diverge in scope and timing.

    Because regimes diverge, most firms must screen against several lists at once — see OFAC screening and EU sanctions screening.

    Sanctions vs embargo

    The terms are often used interchangeably, but an embargo is a subset of sanctions: a broad ban on trade with a country, or on a class of goods such as arms or dual-use technology. Sanctions also cover asset freezes on named persons, travel bans, sectoral finance restrictions and prohibitions on specific services — measures that can bite even where no embargo exists.

    What compliance requires

    A defensible sanctions programme screens customers, beneficial owners and counterparties at onboarding and continuously thereafter, screens payments in real time, uses fuzzy matching tuned against transliteration and alias variants, resolves alerts with documented rationale, and freezes and reports confirmed matches within statutory deadlines. ComplianceSuite runs this through sanctions screening, PEP screening, UBO verification and the ComplianceSuite platform, with every alert decision retained for supervisors. New to screening?

    FAQ

    What are sanctions?

    Sanctions are restrictive measures imposed by governments or international bodies — such as the UN, EU, US and UK — against countries, entities, vessels or individuals to advance foreign-policy or national-security objectives. For financial institutions they translate into prohibitions on dealing with listed parties, freezing their assets, and reporting exposures to the relevant authority.

    What types of sanctions exist?

    The main categories are targeted (smart) sanctions against named persons and entities, sectoral sanctions restricting specific industries or financial instruments, comprehensive country programmes prohibiting nearly all dealings with a jurisdiction, and secondary sanctions that reach non-domestic firms transacting with sanctioned parties.

    What is the difference between sanctions and an embargo?

    An embargo is one form of sanction: a broad prohibition on trade with a country or on specific goods such as arms. Sanctions is the wider term, covering asset freezes, travel bans, sectoral restrictions and financial prohibitions against named individuals and entities as well as whole jurisdictions.

    Who has to comply with sanctions?

    Sanctions bind far more than banks. Any business within the jurisdiction of an imposing authority — payment firms, insurers, crypto platforms, exporters, shipping and logistics companies, professional-services firms — must not deal with listed parties, and US programmes can reach non-US firms through dollar clearing and secondary measures.

    How do firms screen for sanctions?

    Firms screen customers, beneficial owners, counterparties and payment messages against consolidated sanctions lists at onboarding and continuously afterwards, using fuzzy matching to catch spelling and transliteration variants, then investigate and document each alert. Because lists change without notice, daily rescreening of the existing customer base is expected.

    What are the penalties for a sanctions breach?

    Sanctions breaches are generally strict liability, meaning intent is not required. Consequences include substantial civil penalties, criminal prosecution in serious cases, loss of correspondent banking access, and public enforcement notices — often with remediation obligations attached.
