The Office of Financial Sanctions Implementation (OFSI) is an office within HM Treasury responsible for improving the understanding, implementation and enforcement of financial sanctions in the United Kingdom. It issues guidance and licences, investigates suspected breaches and takes enforcement action. Its responsibilities also include implementing the price cap on Russian oil.[1]
OFSI was established on 31 March 2016. George Osborne, then Chancellor of the Exchequer, described financial sanctions as a foreign-policy and national-security instrument and said the office would work with businesses and other government bodies to improve compliance and detect breaches.[2]
Its work affects financial institutions, businesses, charities and individuals. OFSI's guidance states that UK citizens must comply with financial sanctions wherever they operate, as must entities established under UK law operating overseas and anyone carrying out relevant activities within UK territory.[1]
Establishment and purpose
The March 2016 announcement placed OFSI within HM Treasury and committed it to providing a service to the private sector while working with law enforcement. It linked the office's creation both to implementing foreign-policy and national-security objectives and to maintaining confidence in the UK financial-services sector.[2]
Functions and relationship to sanctions policy
OFSI explains that financial sanctions commonly involve freezing assets, prohibiting the provision of funds or economic resources to designated people, and restricting access to financial services or markets. Its licensing function can authorise activities otherwise prohibited under sanctions legislation.[1]
The Foreign, Commonwealth and Development Office publishes the UK Sanctions List. OFSI's guidance cautions that an asset freeze and some financial-services restrictions can extend to businesses or other organisations owned or controlled by a designated person, rather than only entities explicitly named on the list.[1]
Enforcement powers
Changes introduced through the Economic Crime (Transparency and Enforcement) Act 2022 enabled OFSI to impose civil monetary penalties on a strict civil liability basis for relevant breaches after 15 June 2022. In explaining the changes, director Giles Thomson said that OFSI would no longer have to prove knowledge or reasonable cause to suspect a breach, but would still have to establish that a breach had occurred. The criminal legal test was not changed by this measure.[3]
The changes also allowed OFSI to publish details of financial-sanctions breaches where it had not imposed a monetary penalty. Thomson said that voluntary disclosure, efforts to prevent breaches, proportionality and the public interest would remain relevant to enforcement decisions; strict civil liability did not mean that every breach would attract a penalty.[3]
Development of the office
In a tenth-anniversary account published on 31 March 2026, Giles Thomson described the expansion of OFSI's guidance, threat assessments, sector-specific engagement and use of general licences. He said that enforcement increasingly used data and intelligence, together with warning letters, public disclosures and civil monetary penalties.[4]
| Review period | Amount | Measure |
