UK’s FCA Publishes Final Crypto Framework as Another Step to Integrate Crypto into Traditional Financial System

The UK's Financial Conduct Authority on June 30 published its final cryptoasset policy package, completing its regulatory roadmap and establishing prudential, market abuse and stablecoin requirements ahead of a mandatory authorization regime due to begin on Oct. 25, 2027.

The rules apply to crypto trading platforms, intermediaries, custodians, stablecoin issuers, lending and borrowing providers, staking firms and certain decentralized finance businesses where an identifiable controlling entity exists, according to the FCA's executive summary.

Firms conducting regulated cryptoasset activities in the U.K. will be required to obtain FCA authorization. Existing registrations under the Money Laundering Regulations will not convert automatically, the regulator said. 

The authorization window will open on Sept. 30, 2026, and close on Feb. 28, 2027. Firms applying within that period may continue specified activities under transitional savings provisions while their applications are assessed, subject to the conditions set out in the legislation.

The FCA said it will begin offering pre-application support meetings in July to help firms prepare submissions.

Capital standards and market abuse requirements

The prudential framework introduces capital, liquidity and stress-testing requirements for crypto firms, while incorporating existing financial services standards where the FCA considers risks to be comparable.

Following industry feedback, the regulator reduced the K-SII capital coefficient for stablecoin issuers to 1% from the 2% proposed in consultation documents, describing the change as a more proportionate approach for larger issuers.

The FCA also abandoned a previously proposed two-tier capital classification system for qualifying cryptoassets. Under the final rules, eligible cryptoassets admitted to U.K. qualifying cryptoasset trading platforms will face a single 40% net risk position requirement and a 40% counterparty default volatility adjustment.

The market abuse framework introduces rules covering insider dealing, market manipulation and disclosure of inside information.

The FCA retained an industry-led approach for large U.K. qualifying cryptoasset trading platform operators while narrowing proposed onchain monitoring requirements and refining obligations relating to intermediary notifications and legitimate market practices.

Trading venues will also be required to conduct due diligence on assets admitted to trading, satisfy admission standards and publish qualifying cryptoasset disclosure documents. The regulator removed an exemption that previously allowed fungible cryptoassets to be listed without additional disclosure documentation.

FCA Stablecoin framework and consumer protections

The final stablecoin regime establishes requirements covering reserve assets, safeguarding arrangements, redemptions and disclosures to token holders.

The FCA removed proposals requiring firms to estimate redemption forecasts when determining backing assets, allowed limited intragroup custody arrangements subject to safeguards and permitted stablecoin reserve pools to hold excess assets of up to 5%.

The regulator also introduced requirements designed to ensure holders retain access to historical disclosures and receive clearer information regarding withdrawal and redemption rights.

The framework applies broader FCA standards, including the Consumer Duty, senior managers rules, operational resilience requirements and financial crime controls across regulated cryptoasset activities.

The FCA said it will publish additional policy work later this year covering decentralized finance guidance, distributed ledger technology operational resilience, financial crime requirements and the treatment of systemic stablecoins alongside the Bank of England.

David Geale, the FCA's executive director of payments and digital finance, described the publication as a significant milestone for the U.K.'s crypto regulatory framework.

"We've created a framework that doesn't force firms to choose between regulatory certainty and room to innovate," Geale said in a statement. "For consumers, it means firms will be held to similar standards to other financial providers, though we can't regulate away risk."

Until the new regime takes effect in October 2027, the FCA said its oversight of crypto firms will continue to focus on financial promotions and anti-money laundering requirements.
