UK's New Crypto Regulations: A Potential Pitfall for Unwary Firms

The UK's Financial Conduct Authority has unveiled proposed crypto regulations that could broaden the definition of custody, potentially ensnaring platforms and software providers who do not consider themselves custodians. The FCA's Cryptoasset Perimeter Guidance, published recently, outlines several technical pitfalls for firms handling clients' crypto assets. 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-compounding tools, could lead to the loss of their pure tech exemption and require full approval for arranging staking. The regulator has stated that its new perimeter will enhance consumer protections and support fair, transparent, and orderly markets as the sector matures. Notably, the FCA has addressed the 'shadow custody' issue, clarifying that if a crypto service provider can theoretically override a client's authority, it is considered a custodian, regardless of whether it guarantees not to exert that power. The document emphasizes that the use of smart contracts, public blockchains, or decentralization elements does not exempt an arrangement from regulation. For stablecoin issuers, the rules are straightforward: 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 is seeking feedback on these proposals until June 3, 2026, and intends to publish finalized rules in policy statements this summer, followed by the final perimeter guidance in September. The regulatory roadmap requires all entities providing crypto services to transition from the current money-laundering registration systems to a stricter approval regime under the UK's Financial Services and Markets Act. Firms that wish to continue operating under the new regulations have a five-month application window, from September 30, 2026, to February 28, 2027, and failure to meet this deadline may result in penalties, suspensions, or permanent closures. Only those who apply during the application period will benefit from the 'savings provisions' that allow them to continue operating while the regulator deliberates.
