UK Crypto Regulations: Hidden Pitfalls for Unwary Firms

The UK's Financial Conduct Authority has unveiled proposed crypto regulations that could significantly broaden the definition of custody, potentially ensnaring platforms and software providers that do not consider themselves custodians. The FCA's Cryptoasset Perimeter Guidance, published recently, highlights several technical pitfalls 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 platform holding client assets for more than a day during trade settlement may be classified as a regulated custodian, necessitating a full safeguarding license. Additionally, validators and node operators must exercise caution, as providing 'added value' features such as user dashboards or yield tools may lead to the loss of their tech exemption, requiring them to seek 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 guidance also stipulates that stablecoin issuance 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 FCA 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 stricter approval regime under the UK's Financial Services and Markets Act. Firms that fail to apply for approval within the designated five-month window, from September 30, 2026, to February 28, 2027, risk facing fines, suspensions, and potential closure. Only those who submit their applications during this period will be eligible for 'savings provisions,' allowing them to continue operating while the regulator reviews their applications.
