UK Crypto Regulations: Hidden Pitfalls for Unwary Firms

The UK's Financial Conduct Authority has introduced proposed crypto regulations that could significantly broaden the definition of custody, potentially encompassing platforms and software providers that do not identify as custodians. The FCA's Cryptoasset Perimeter Guidance, published recently, highlights several technical complexities that firms handling client crypto assets must be aware of. A key aspect of the rules is the 24-hour threshold for custody, whereby any firm or crypto platform holding client assets for more than a day during trade settlement may be classified as a regulated custodian, necessitating a full safeguarding license. Validators and node operators must also exercise caution, as providing 'added value' features such as user dashboards or yield tools may result in the loss of their tech exemption, requiring them to obtain approval for arranging staking. The FCA has emphasized its commitment to strengthening consumer protections and promoting fair, transparent markets as the sector evolves. Notably, the regulator has addressed the issue of 'shadow custody,' clarifying that if a crypto service provider can theoretically override a client's authority, it will be considered a custodian, regardless of whether it intends to exert that power. The FCA has also provided guidance on stablecoin issuance, stating that it is only permissible if the issuer is established in the UK and manages the entire lifecycle, from initial offering to redemption and reserve maintenance. The regulator has invited feedback on these proposals until June 3, 2026, and intends to publish finalized rules in the summer, followed by the final perimeter guidance in September. The new regulations will require all entities providing crypto services to transition from the current money-laundering registration system to a more stringent approval regime under the UK's Financial Services and Markets Act. Firms that fail to meet the application deadline of February 28, 2027, risk facing fines, suspensions, and potential closures.
