FCA publishes final crypto rules — authorisation, capital, market-integrity and stablecoin standards, mandatory from October 2027
Crypto trading platforms, intermediaries, custodians, stablecoin issuers and staking firms must obtain FCA authorisation — the gateway opens 30 September 2026 and the mandatory regime takes effect 25 October 2027
Change
On 30 June 2026 the Financial Conduct Authority (FCA) published its final cryptoasset rules, requiring firms that support buying, trading or holding crypto to obtain FCA authorisation; the authorisation gateway opens 30 September 2026, applications run to 28 February 2027, and the mandatory regime takes effect 25 October 2027.
Why it matters
The FCA's final rules complete its crypto roadmap after February 2026 legislation brought cryptoassets into its remit. Authorised firms must meet financial-resilience requirements (capital and stress testing) and new market-integrity rules on insider trading and market manipulation; stablecoin issuers face specific, tailored capital and trading standards. The authorisation gateway opens 30 September 2026 with applications to 28 February 2027, ahead of the mandatory regime on 25 October 2027; until then FCA crypto oversight stays limited to financial promotions and AML. Further FCA work follows: a September 2026 policy statement on the perimeter, and later consultations on DeFi guidance, DLT operational resilience, the Financial Crime Guide, and joint FCA/Bank of England treatment of systemic stablecoin issuers.
Implications
- — Crypto trading platforms, intermediaries, custodians, stablecoin issuers and staking firms must apply for FCA authorisation in the gateway window of 30 September 2026 to 28 February 2027 — firms that do not obtain authorisation cannot start or continue trading in the UK once the mandatory regime takes effect on 25 October 2027.
- — Risk and compliance teams at crypto firms must build and evidence financial-resilience controls — capital adequacy and stress testing — as authorisation conditions, and should use the FCA's pre-application support meetings available from July 2026 to prepare.
- — Crypto firms must implement market-integrity controls against insider trading and market manipulation — the FCA is applying established financial-services standards, including the Consumer Duty, where crypto risks are comparable.
- — Stablecoin issuers must meet the FCA's specific stablecoin standards and tailored capital and trading rules, and should track the FCA–Bank of England consultation later this year on how rules apply once an issuer is recognised as systemic by HM Treasury — systemic issuers face a move to joint FCA/BoE regulation.
Who is affected
- — Crypto trading platforms, intermediaries, custodians and firms arranging staking operating in or into the UK
- — Stablecoin issuers operating in the UK
- — Risk and compliance teams at cryptoasset firms
- — Firms preparing UK crypto authorisation applications
