A Sanctioned Designated National (SDN) is an individual, organisation, or entity that has been identified by a governing authority, such as the Office of Foreign Assets Control (OFAC) in the United States, for their involvement in illegal activities or association with sanctioned regimes. As a result, SDNs are subject to financial and economic restrictions that limit their access services.

The primary aim of imposing sanctions on designated nationals is to deter and penalise those participating in unlawful activities, such as terrorism, drug trafficking, and human rights abuses, or those associated with countries subject to comprehensive sanctions. These restrictions can include asset freezing, prohibitions on transactions, and denial of specific licenses or permits.

Financial services providers operating within corporate and commercial sectors must ensure compliance with the requirements associated with SDNs. This entails implementing robust screening processes, risk assessments, and due diligence procedures to identify and report any dealings with SDNs. Failure to comply with these regulations can lead to substantial penalties, reputational damage, and potential exclusion from the financial sector.

In conclusion, a Sanctioned Designated National is an individual or entity facing financial and economic restrictions due to their involvement in illicit activities or links to sanctioned regimes. Financial services organisations must uphold their obligations in relation to SDNs, ensuring that they do not facilitate or engage in transactions with these restricted parties. Strict compliance with SDN regulations is crucial to maintaining the integrity and stability of the global financial system.
