Firms have until Feb 28, 2027 to apply for a crypto licence under the FCA's final rulebook. Stablecoin capital requirements halved to 1%. DeFi with no controller stays exempt.
Britain's Financial Conduct Authority published its final crypto rulebook Tuesday, setting a hard deadline for firms to get licensed or exit the market. Applications open September 30, 2026, and close February 28, 2027. Full enforcement starts October 25, 2027.
The framework covers trading venues, wallet providers, stablecoin issuers, staking operations, crypto lending platforms, and some DeFi protocols. The FCA said DeFi will face regulation only when an identifiable party maintains operational control. Firms already registered for anti-money laundering compliance do not get automatic authorisation – they must submit fresh applications alongside new entrants.
Exchange platforms face tougher listing standards. The FCA scrapped a previous exemption that let certain tokens list without disclosure documents. For qualifying digital assets, exchanges will apply a single 40% net risk position standard, replacing an earlier plan that split assets into separate risk buckets.
Stablecoin rules got lighter after industry feedback. Issuers no longer need to provide redemption projections for their reserve holdings. The capital reserve requirement for stablecoin creation dropped to 1%, down from the 2% initially proposed. Reserve funds must sit in a legal trust structure. Issuers can hold up to 5% in additional backing reserves and use restricted affiliated custody, provided protections are in place.
David Geale, the FCA's executive director overseeing payments and digital finance, said the framework gives businesses regulatory clarity without forcing them to choose between certainty and innovation. Matthew Long, the FCA's director managing payments and digital assets, said the regulator will develop DeFi guidance separately. "Genuine DeFi," where no single entity controls operations, will stay outside this regulation's scope, Long said.
The FCA will hold an informational webinar July 17. Pre-application consultation sessions for firms start the same month. A further policy statement is due in September, clarifying how regulatory boundaries apply to crypto operations generally.
In the second half of this year, the FCA will launch a separate consultation on DeFi guidance and operational resilience standards for blockchain-using firms. It also plans to consult with the Bank of England on how to regulate stablecoin issuers that HM Treasury designates as systemically important.
Market manipulation rules now address wash trading and price manipulation. The FCA kept an industry-led approach for major exchange operators but reduced blockchain monitoring obligations for those larger entities. It also refined rules on disclosure of inside information.
