The Financial Conduct Authority has released its comprehensive regulatory framework for cryptoassets in the United Kingdom, marking the most significant shift in digital asset oversight since the introduction of the anti-money laundering registration regime in 2020. The framework, which runs to over 200 pages, establishes distinct licensing categories for exchanges, custodians, stablecoin issuers, and decentralised finance platforms, with full implementation expected by Q1 2026. FCA chief executive Nikhil Rathi described the publication as a "defining moment" for the UK's ambitions to become a global hub for responsible crypto innovation.

Under the new rules, all cryptoasset service providers operating in or marketing to UK consumers must obtain authorisation from the FCA, replacing the existing registration-only approach. The framework introduces capital adequacy requirements scaled to the size and risk profile of each firm, with minimum thresholds starting at £125,000 for smaller operators and rising to £5 million for major exchanges. Consumer protection measures include mandatory segregation of client assets, clear disclosure of risks, and a prohibition on offering leveraged products above 2x to retail investors.

Industry reaction has been broadly positive, with trade body CryptoUK calling the framework "proportionate and forward-looking." However, some smaller firms have raised concerns about compliance costs, estimating that the new requirements could add between £250,000 and £800,000 in annual operating expenses. The Treasury has committed £15 million to support a regulatory sandbox programme designed to help innovative startups navigate the new regime, while the FCA has pledged to process applications within 90 business days of submission.
