OFSI – Office of Financial Sanctions Implementation (UK)

OFSI (Office of Financial Sanctions Implementation) is a dedicated unit within HM Treasury responsible for implementing and enforcing UK financial sanctions since March 2016. OFSI administers all UK sanctions regimes, issues licences for permitted transactions, and imposes civil monetary penalties for breaches.

• Civil penalties: Up to £1 million or 50% of the estimated value of the funds or economic resources involved (whichever is higher)
• Prosecution: Coordinates with the Crown Prosecution Service for serious breaches
• Licences: OFSI can grant exceptions for humanitarian, diplomatic or other purposes
• UK Sanctions List: The UK Sanctions List (maintained by FCDO) replaced the former OFSI Consolidated List in January 2026 and contains all designated persons and entities
• Oil Price Cap: OFSI administers the Oil Price Cap on Russian oil products

Before OFSI’s establishment in March 2016, UK financial sanctions implementation was spread across multiple agencies. The increasing complexity of sanctions regimes — particularly following Russia sanctions in the wake of the 2014 Crimea annexation — necessitated a centralised authority.

In January 2017, the Policing and Crime Act 2017 (Section 146) created the legal basis for OFSI’s power to impose civil monetary penalties.

Brexit meant the UK could no longer directly apply EU sanctions regimes. The Sanctions and Anti-Money Laundering Act 2018 (SAMLA) created the legal basis for independent UK sanctions policy post-EU departure. From 1 January 2021, the UK operates entirely independently of EU sanctions but continues to coordinate closely with the EU, US and other G7 partners.

In February 2022, following Russia’s invasion of Ukraine, sanctions were massively expanded. OFSI played a central role in rapid implementation. The Economic Crime (Transparency and Enforcement) Act 2022 (Royal Assent: 15 March 2022) lowered the burden of proof for OFSI civil penalties from ‘beyond reasonable doubt’ to ‘balance of probabilities’, significantly strengthening OFSI’s enforcement capability.

OFSI has jurisdiction over all individuals and entities operating in the United Kingdom or subject to UK law, including:

• Credit institutions, banks and financial services firms
• Lawyers, accountants and trustees
• Companies with UK nexus
• All transactions in GBP or routed through UK correspondent banks

OFSI administers multiple sanctions regimes (Russia, Iran, North Korea, Belarus, Myanmar, etc.) including the Oil Price Cap on Russian oil products, and coordinates with OFAC (US), EU and other international partners.

• Screening obligation: All customers and transactions must be checked against the UK Sanctions List (maintained by FCDO)
• Asset freezing: Immediate freezing of assets upon a match with the sanctions list
• Reporting duty: Suspicious activity reports to OFSI when sanctions breaches are known or suspected
• Licence requirement: OFSI licence required before any transaction involving designated persons
• No circumvention: Prohibition on indirectly making funds or economic resources available
• Recordkeeping: Documentation of all sanctions checks and reports
