UK FCA opens sweeping crypto regime consultation

TLDR

The UKs Financial Conduct Authority (FCA) has opened a major consultation on how its full crypto regime will work ahead of an October 2027 start date.

1. The FCAs CP26/13 consultation sets out which crypto activities will become regulated, including trading platforms, custody, stablecoins, dealing and staking.
2. Firms serving UK users will need full authorisation under the Financial Services and Markets Act by October 25, 2027, with an application window running from late 2026.
3. Key unknowns include how strictly custody and DeFi are treated, which will determine whether some business models must change or exit the UK market.

Deep Dive

1. What The Consultation Actually Covers

The FCA has published consultation paper CP26/13, asking for feedback on draft cryptoasset perimeter guidance that defines which activities fall under the new regime, including stablecoin issuance, trading venues, safeguarding (custody) and staking services, plus dealing and arranging deals in qualifying cryptoassets. Reports from multiple outlets describe this as the final guidance step before a full FSMA based regime goes live on 25 October 2027, with the consultation open until 3 June 2026. Coverage from Decrypt and others notes that the FCA is taking an activity based perimeter approach, focusing on services like issuers, custodians and platforms rather than simply licensing whole firms in one block.

2. Practical Impact For Crypto Firms

Under the proposals, any exchange, custodial wallet provider, stablecoin issuer or staking service targeting UK users will need full authorisation under FSMA Part 4A, not just anti money laundering registration, before the 2027 go live date. Draft guidance highlighted in analyses from Bitcoin.com and CoinDesk indicates that safeguarding will be interpreted broadly, with firms that hold client assets for more than 24 hours, or can override client authority, treated as regulated custodians that must meet capital, governance and operational standards. Overseas firms serving UK retail customers would also be captured unless they intermediate through an authorised UK firm.

3. Timeline And Key Uncertainties To Watch

According to crypto policy reports, the FCA plans to open its authorisation gateway on 30 September 2026 and close it on 28 February 2027, with firms that apply in time allowed to keep operating while applications are processed. The rulebook itself is described as substantively complete, but there are clear open questions: DeFi treatment will be consulted on separately, and the perimeter around non custodial or composable protocols is not fully resolved. How strictly the FCA applies concepts like the 24 hour custody rule, and how it classifies DeFi front ends and hybrid models, will heavily influence which services remain viable in the UK.

Conclusion

The consultation marks the point where UK crypto moves from patchy promotion and AML rules toward a full financial services style regime that will bite in 2027. For users and firms, the main story is not immediate changes, but the clear timeline and direction: regulated, authorised intermediaries at the center, with DeFi and custodial edges still to be negotiated over the next two years.
