UK FCA Consults on DeFi Resilience and Regulatory Perimeter Exclusions

The UK Financial Conduct Authority (FCA) has published two consultation documents addressing how regulated financial firms manage decentralised finance risks and where statutory boundaries fall under incoming crypto rules ¹². Both consultation periods run through Nov. 18, 2026, ahead of planned final guidance in January 2027 ¹².

The first paper, Guidance Consultation GC26/7, introduces proposed non-Handbook guidance for FCA-authorised firms that deploy DeFi to deliver financial services ². The paper focuses on practical measures to satisfy Senior Management Arrangements, Systems and Controls (SYSC) requirements under SYSC 15A for operational resilience, SYSC 6 for financial crime controls, and compliance with the Money Laundering Regulations ². The FCA noted that while DeFi protocols reduce reliance on traditional intermediaries, automated and open protocols expose companies and clients to distinct operational vulnerabilities and illicit finance risks ¹².

Clarifying the Regulatory Boundary

The second paper, Consultation Paper CP26/36, covers cryptoasset perimeter guidance following recent legislative changes ¹². According to the UK Cryptoasset Business Council (UKCBC), the document outlines specific exclusions introduced by statute, such as technical software services that merely facilitate access to decentralised networks, temporary settlement workflows, proprietary trading, and defined stablecoin holding structures ¹. The perimeter guidance builds on broader regulatory adjustments detailed in earlier discussions on UK crypto regulation ¹².

The supervisory frameworks arrive as the UK prepares for the implementation of the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, which formally brings expanded digital asset activities within the FCA’s remit starting Oct. 25, 2027 ².
