It plays a significant role under His Majesty’s Treasury (HM Treasury) in the United Kingdom to implement and enforce financial sanctions and promote security and stability.
This is an in-depth guide that aims to provide an understanding of OFSI, how it works in the enforcement landscape, and its implications for businesses all over the world, from its functions to penalties for non-compliance.
What Is OFSI?
OFSI is a UK government authority responsible for managing financial sanctions to prevent funds from being exploited for organized crime, terrorism, or other international threats. OFSI is a critical part to play in the UK’s national security and its foreign policy objectives by enforcing financial sanctions.
Key Responsibilities of OFSI:
- Implementing UK Financial Sanctions
OFSI must ensure that all financial sanctions passed by the UK government are effectively applied across sectors.
- Compliance Guidance and Enforcement
OFSI offers guidance, supports compliance efforts, and enforces penalties who breach sanctions regulations.
- Licensing
OFSI can issue licenses to allow activities that would be prohibited by the sanctions under specific circumstances.
- International Collaboration
Law enforcement agencies, regulatory bodies, and international counterparts like the Office of Foreign Assets Control (OFAC) in the U.S. also collaborate with OFSI.
What Are Financial Sanctions?
To achieve specific national and international policy objectives, financial sanctions are imposed on individuals, entities, or states whose activities could contribute to national or global risks.

- Banks and financial institutions
- Law firms, auditors, and accountants
- Corporations of trade, logistics, and supply chains
- Insurance firms and investment entities
- Cryptocurrency and fintech platforms
Consequences of Non-Compliance:
Any failure to follow OFSI sanctions may result in civil penalties, criminal prosecution, and reputational damage to the organizations.
Legal Framework and Key Regulations
OFSI’s enforcement authority stems from a legal framework to provide the necessary mechanisms for the effective implementation of financial sanctions.
| Regulation/Act | Purpose |
| Sanctions and Anti-Money Laundering Act 2018 (SAMLA) | Establishes the UK’s independent sanctions system post-Brexit. |
| Policing and Crime Act 2017 | Grants OFSI enforcement powers, including civil penalty imposition. |
| Counter-Terrorism Act 2008 | Guides processes for freezing assets connected to terrorism financing. |
| Statutory Instruments (SIs) | Define specifics of individual sanctions regimes across various sectors. |
OFSI & International Collaboration
To ensure global enforcement, the UK collaborates with other jurisdictions even though it has its independent sanctions regime after Brexit.
OFSI and OFAC (U.S.)
Even though they have different jurisdictions, OFSI AND OFAC are both significant organizations with shared objectives whose goal is to implement and enforce financial sanctions effectively.
OFSI and the UN
The UK, as a UN member, implements UN-mandated sanctions through OFSI.
OFSI and the EU
The UK and EU have separate sanction regimes post-Brexit, while there are still overlaps due to common geopolitical interests.
Examples of OFSI Sanctions in Action
OFSI includes work that reflects the dynamic geopolitical nature of financial sanctions, with notable case examples, such as:
- Russia Sanctions, 2022-2025
Financial sanctions were imposed on over 1,800 entities and organizations after the Ukraine conflict, which target state revenues, defense and energy sectors.
- Iran Sanctions
This includes Iran’s human rights violations and nuclear program.
- Counter Terrorism Financing
Sanctions on individuals who engage in terrorist groups, such as Al-Qaeda and ISIS.
How Does OFSI Enforce Compliance?
Not complying with the sanctions enforced by OFSI can lead to substantial penalties as the measures are preventive and punitive.
Potential Penalties:
- Money fines of over £1 million or 50% of the breach value (whichever is higher).
- Criminal charges, imprisonment, or unlimited fines
- Reporting the breaches to authorities like the Financial Conduct Authority (FCA). Steps to Stay Compliant with OFSI Rules
