FCA publishes final rules for comprehensive UK crypto regulatory regime
The FCA reversed course on several restrictive proposals, opening the door to matched principal trading and loosening retail lending limits ahead of an October 2027 launch.
The UK’s financial regulator on Tuesday unveiled its final crypto asset regulatory framework, requiring firms offering a wide range of digital asset services to obtain full authorization while introducing new rules aimed at strengthening consumer protection and market integrity.
The Financial Conduct Authority (FCA) said the package of policy statements marks a major milestone in the UK’s Cryptoasset Roadmap and establishes a comprehensive regime covering activities including crypto trading, custody, lending, staking and stablecoin issuance.
Most of the new regulated activities will come into force on Oct. 25, 2027, giving firms time to prepare for the new requirements.
Expanded regulatory oversight
The reforms greatly expand the FCA’s oversight of the sector. Crypto firms operating in Britain have until now largely been subject to anti-money laundering registration requirements and financial promotion rules.
Under the new regime, firms carrying out regulated crypto asset activities will generally be required to obtain authorization under the Financial Services and Markets Act.
The FCA said the framework is intended to provide clear and predictable rules for the industry while strengthening protections for consumers and supporting innovation.
Stablecoin framework
The new regime introduces dedicated rules for stablecoin issuers, including requirements that qualifying stablecoins be fully backed by reserve assets and redeemable at par.

Following consultations with industry participants, the regulator said it had simplified certain reserve management requirements, adjusted redemption timelines and allowed limited intragroup custody arrangements subject to safeguards.
New standards for crypto service providers
Crypto trading platforms and intermediaries will also face new obligations on governance, disclosures and best execution, while custodians must comply with enhanced safeguards covering client asset protection, record-keeping, reconciliation and private key management.
Lending and borrowing platforms will be required to strengthen protections for retail customers through enhanced disclosures, appropriateness assessments and collateral safeguards.
Market abuse and prudential reforms
The FCA also finalized a market abuse regime for crypto assets, introducing rules covering insider dealing, market manipulation and disclosure obligations for firms operating qualifying crypto asset trading platforms.
Following feedback from consultations, the regulator also revised parts of its proposed prudential framework. It reduced the capital coefficient for stablecoin issuance from 2% to 1% and simplified the treatment of market risk for qualifying crypto assets admitted to UK trading platforms.
The regulator said existing registrations under the UK’s anti-money laundering regime will not automatically convert to authorization under the new framework. Firms wishing to rely on transitional arrangements will be able to apply between Sept. 30, 2026 and Feb. 28, 2027.
The FCA said it would continue to develop policies in areas including decentralized finance, crypto asset derivatives, financial crime guidance and regulatory reporting, and plans to review the regime around two years after it takes effect.
