FCA publishes guidance clarifying which crypto activities will need UK authorisation

The U.K.’s Financial Conduct Authority on Wednesday published guidance telling crypto firms how the country’s upcoming cryptoasset regime applies to their business and which activities are likely to need FCA authorization, giving companies a clearer compliance roadmap before applications open on Sept. 30.

The practical significance is timing. The U.K. has already published the core rules for its new crypto framework, and the full regime is due to take effect on Oct. 25, 2027. For firms now preparing to apply, the key question is whether their business model falls inside the regulated perimeter. The FCA said the new guidance is intended to help firms understand how the law underpinning the regime applies to them and “sets out which activities may require FCA authorisation.”

The guidance covers several of the main business lines in the crypto sector. The FCA said it addresses issuing qualifying stablecoins, operating cryptoasset trading platforms, dealing in and arranging deals in cryptoassets, safeguarding cryptoassets, and arranging cryptoasset staking. In practice, that makes the document particularly relevant for exchanges, custodians, stablecoin issuers, staking businesses and related service providers trying to determine whether they will need approval from the regulator.

The publication sits within the U.K.’s new statutory crypto framework created by the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, which were made in February. The FCA said it had already finalized its crypto rules and guidance in June 2026, and that this latest publication is meant to clarify the regulatory perimeter ahead of the authorization process.

To help firms prepare, the FCA said it is offering pre-application support discussions and webinars. That support is aimed at businesses that need to understand not just the rules themselves, but whether the activities they carry out, or plan to carry out, will bring them into scope of the new regime once the gateway opens at the end of this month.

David Geale, executive director of consumers, payments and competition at the FCA, said: “We are building a crypto regime that firms, consumers and international partners can trust. Getting ready for regulation starts with understanding how the regime applies to your business. This guidance gives firms the clarity they’ve asked for so they can prepare with confidence.”

The FCA also said the U.K. government has made targeted legal amendments, including limited exclusions and clarifications for certain technical services providers. But the regulator said those changes will not affect most crypto firms, and businesses can use the new guidance now as they prepare for authorization. The FCA said it will consult in October on targeted updates to reflect those legal changes, including questions touching on areas such as stablecoins, proprietary trading and market making, some technology providers, decentralized protocols, certain safeguarding arrangements and financial promotions.
