Exploring the Challenges of Cryptocurrency Regulation: Outlining the Threats Identified by the OFSI for the Year 2025
The UK's Office of Financial Sanctions Implementation (OFSI) has published a sector-specific Cryptoassets Threat Assessment on 21 July 2025, highlighting significant risks and challenges related to financial sanctions compliance in the UK cryptoasset sector from January 2022 to May 2025.
Key Findings
The report reveals that over 7% of all suspected sanctions breach reports received by OFSI since January 2022 involved UK cryptoasset firms, predominantly linked to sanctions evasion activities involving Russia (90%) and Iran (10%). It also points out significant under-reporting by crypto firms of suspected sanctions breaches since August 2022.
Key threats identified include inadvertent or delayed sanctions breach reporting, direct and indirect exposure to sanctioned individuals and entities such as the Russian exchange Garantex, and sophisticated evasion tactics by actors from North Korea and Iran. Emerging evasion typologies involve the use of non-fungible tokens (NFTs), meme coins, and stablecoins to circumvent controls.
Recommendations
The report urges UK cryptoasset firms to move beyond passive compliance and take proactive measures to detect, prevent, and report sanctions breaches. The use of advanced tools such as blockchain analytics and real-time transaction monitoring is essential for identifying suspicious activity and exposure to sanctioned persons.
Firms should incorporate cryptoasset-related sanctions risks into their overall risk assessments, ensuring robust due diligence and compliance controls. They should also be alert to sanctions evasion red flags, and where multiple red flags are present, undertake enhanced due diligence before completing transactions. Timely reporting of suspected breaches to OFSI is critical to compliance and enforcement.
Strengthening sanctions compliance frameworks is urgently needed as OFSI signals it will intensify enforcement and criminal liability for breach through cryptoassets.
Implications for UK Cryptoasset Firms
The report serves as a wake-up call for firms, highlighting the need to be proactive in updating systems, training, and policies to account for emerging threats, vigilant in screening for transaction and counterparty risks, and cooperative with their regulators and with OFSI in reporting suspected sanctions breaches.
The report also reflects the growing momentum behind regulation of the sector, with several key regulatory events mentioned. For instance, the Financial Conduct Authority (FCA) introduced the cryptoasset financial promotions regime for all firms promoting cryptoassets in the UK in October 2023, and the UK Government published draft legislation aimed at bringing the operation of a cryptoasset trading platform, intermediation, cryptoasset lending and borrowing, staking, and decentralised finance (DeFi) within the FCA's remit in April 2025.
Conclusion
The report underscores the evolving threats that cryptoassets pose to the UK’s sanctions regime and sets out a clear expectation that cryptoasset firms adopt rigorous, technology-enabled compliance measures to mitigate these risks. This sector-specific threat assessment is part of OFSI’s broader efforts in 2025 to address sanctions risks across multiple sectors.
The report also serves as a critical resource for UK cryptoasset firms and stakeholders aiming to strengthen compliance and mitigate exposure to illicit activity. It is a reminder that the cryptoasset sector, like any other, must adhere to financial sanctions regulations to maintain the integrity of the UK's financial system.
