The UK Financial Conduct Authority has released its final regulatory framework for crypto assets, setting February 28, 2027 as the deadline for firms to submit authorization applications if they want to keep operating legally in the country. The new regime is scheduled to take effect on October 25, 2027, with the application window opening in September 2026. Covered activities include trading platforms, custodians, stablecoin issuers, staking providers, and other intermediaries.
David Geale, the FCA’s executive director for payments and digital finance, said the framework is designed so firms do not have to choose between regulatory certainty and room to innovate. The authority’s position is clear: crypto businesses will be supervised to standards aligned with those applied in traditional finance.
Existing AML registration will not convert into a full license
Firms already registered under the UK’s anti-money laundering rules will not be grandfathered into the new system. That status will not automatically convert into a full authorization, so companies will need to file fresh applications. To ease the shift, the FCA introduced transitional “savings provisions,” allowing businesses already operating in the UK to continue offering some services while their applications are being processed.
The regulator also said it will begin offering pre-application booking sessions next month. An online briefing is scheduled for July 17, and another policy statement is due in September to clarify how the regulatory perimeter applies across different types of crypto-asset activity.
Capital resilience and market abuse controls move to the center
The framework brings several major requirements together under one regime. Authorization becomes mandatory for relevant crypto firms operating in the UK. Companies will also face capital adequacy and stress-testing expectations designed to assess whether they can withstand severe market shocks.
Market integrity rules are another major feature. The FCA said it will target pump-and-dump schemes, wash trading, and insider dealing. Consumer protection obligations are also part of the package, including standards on segregation of client assets, disclosures, and complaint handling that mirror requirements long seen in mainstream financial services. For firms using distributed ledger technology, the regulator plans separate consultation on operational resilience.
Stablecoin framework adds statutory trust and 5% reserve buffer
Stablecoin issuance rules were adjusted in several places. The FCA kept the core structure but simplified reserve composition requirements and dropped a previous obligation to provide forecast redemption estimates. It also introduced a statutory trust requirement so reserve assets are legally separated from an issuer’s own assets.
The rules remove undesignated reserve fund accounts and tighten transparency around how funds are used. Stablecoin issuers must grant users a clear right of redemption. They may also hold up to 5% excess assets in the reserve pool as a buffer, while limited intragroup custody is allowed where safeguards are in place. The FCA described this as a baseline regime for issuance. Later this year, it plans to consult jointly with the Bank of England on how central bank-level standards should apply to issuers considered systemically important by HM Treasury.
DeFi remains subject to case-by-case assessment
On DeFi, the FCA kept a narrower line. Matthew Long, the FCA’s director for payments and digital assets, said the authority will assess applicability on a case-by-case basis. In his words, “true DeFi,” where no identifiable person is carrying out the activity, sits outside the perimeter.
That leaves projects that describe themselves as decentralized but still retain a centralized operating entity more exposed to supervision. The FCA said separate consultation on DeFi guidance and DLT operational resilience is expected later this year, alongside updates to financial crime guidance covering crypto-asset businesses.
The UK shifts from registration to a full licensing structure
The package shows the UK is moving beyond an anti-money laundering registration model and into a broader licensing regime that combines capital rules, conduct standards, client asset protections, and stablecoin issuance requirements. For exchanges and custodians with UK operations, the timeline is now defined, but the compliance bar is also much higher.
