UK FCA launches stablecoin and crypto consultation

TLDR

The UKs Financial Conduct Authority has opened a major consultation on how its new cryptoasset regime will apply to stablecoins, trading, custody, and staking.

1. The consultation explains which crypto activities will be regulated, including issuing qualifying stablecoins, operating trading platforms, custody, dealing and arranging deals, and staking.
2. Firms serving UK users, including overseas exchanges and stablecoin issuers, will need full authorisation under UK financial services law, with an application window from late 2026.
3. The regime is planned to go live in October 2027, so the next 1824 months are about shaping final rules and preparing business models and compliance.

Deep Dive

1. What The FCA Has Launched

The FCA has published draft perimeter guidance explaining how the UKs new crypto regulations will apply in practice, following the February 2026 Financial Services and Markets Act 2000 (Cryptoassets) Regulations that brought crypto under its remit.

The guidance consultation covers six activity clusters, including issuing qualifying stablecoins, safeguarding cryptoassets, running trading platforms, dealing as principal or agent, arranging deals, and arranging staking services for users. This is laid out in detail in the FCA-focused community summary on perimeter guidance.

Feedback runs until 3 June 2026, and this phase is about clarifying scope and interpretation rather than rewriting the primary law itself.

2. Who Is In Scope And What Changes

The regime targets both UK and overseas firms that offer regulated crypto services to UK customers, including exchanges, custodians, stablecoin issuers, and staking providers. The FCA is explicit that existing anti-money-laundering registrations will not automatically convert into full permissions.

Under the plan, crypto businesses must obtain full authorisation under the Financial Services and Markets Act to continue operating, with an authorisation gateway open from 30 September 2026 to 28 February 2027, as highlighted in the implementation timeline.

The approach is activity-based: authorisation hinges on what you do (issuing, safeguarding, operating a venue, etc.), not just who you are, which aligns with analysis of the FCAs perimeter in coverage of regulated activities.

3. Timeline And Open Questions To Watch

The FCA aims to finalise the core rules this summer, with more detailed perimeter guidance expected in autumn 2026, ahead of the full regime taking effect on 25 October 2027. That gives firms roughly 18 months from the gateway opening to adapt systems, disclosures, and capital models.

DeFi and non-custodial systems remain a grey area: the FCA has signalled separate consultations on DeFi and distributed-ledger operational resilience later in 2026, and current commentary notes that non-custodial protocols sit awkwardly in an intermediary-focused perimeter.

Key practical milestones to track are: the June 2026 consultation deadline, summer policy statements, the September 2026 authorisation opening, and clarity on how (or if) truly decentralised protocols will be drawn into scope.

Conclusion

The FCA consultation marks the UKs shift from narrow marketing/AML rules to a full financial-services framework for stablecoins and crypto platforms. Over the next two years, the combination of clear timelines and an activity-based perimeter should reduce legal uncertainty but significantly raise compliance expectations for any crypto business serving UK users.
