Learning objectives
- Distinguish current MLR registration, financial-promotion rules and the forthcoming FSMA authorisation regime.
- Understand the 2026–2027 transition timetable without treating MLR registration as FSMA authorisation.
- Identify why activity, territorial nexus and communication route must be analysed separately.
What the rule or control is
The FCA currently supervises relevant UK cryptoasset businesses for AML/CTF under the MLRs. Registration is not equivalent to full FSMA authorisation and does not imply that the FCA has approved the commercial merits of a cryptoasset. Separately, the UK financial-promotion regime applies broadly to qualifying cryptoasset promotions communicated to UK consumers, including by overseas firms.
The forthcoming FSMA regime materially changes the perimeter. FCA guidance current at 22 August 2026 states that applications for the new regime open on 30 September 2026, the application period runs to 28 February 2027, and the regime is intended to commence on 25 October 2027. Firms carrying on the new regulated cryptoasset activities will need FSMA authorisation or an appropriate variation of permission.
A compliance analysis should therefore start with the actual activity: exchange, custody, dealing, arranging, staking-related service, lending-related service or another regulated activity. It should then ask where the business is carried on, who the customer is, and whether a communication is a financial promotion. Registration under one regime does not automatically satisfy another.
Decision framework
| Question | Why it matters |
|---|---|
| Jurisdiction | Rules differ by customer, entity, activity, location and regulator. |
| Legal classification | The same commercial label can cover legally different products or activities. |
| Evidence | Keep primary-source rules, transaction evidence and dated assumptions. |
| Change control | Re-check when legislation, guidance, product design or customer journey changes. |
Worked example and thought exercise
A UK exchange is FCA-registered under the MLRs in August 2026. It plans to continue operating after October 2027. The registration allows the firm to operate its current in-scope MLR business, but it does not automatically confer the future FSMA permission. The firm must map its activities, prepare for the authorisation gateway and continue complying with the financial-promotion regime meanwhile.
Thought exercise: Which fact in the example would most change the legal, tax or compliance conclusion if it were different?
Common mistakes and practical workflow
- Assuming FCA MLR registration means the firm is fully authorised under FSMA.
- Ignoring the separate financial-promotion perimeter for overseas firms marketing to UK consumers.
- Quoting a future-regime date without checking the FCA's latest implementation timetable.
- Treating the label 'crypto business' as the legal test instead of analysing specific activities.
Practical workflow
- Define the exact activity, asset, customer and jurisdictions.
- Find the current legislation/regulator or tax-authority source rather than relying on a secondary summary.
- Record the rule version/date and the facts used in the analysis.
- Document controls, evidence and any uncertainty or exceptions.
- Escalate to qualified legal, compliance or tax advice where the decision is material.

FAQs
❓ Is this lesson legal or tax advice?
No. It is educational. Rules depend on jurisdiction, facts and date; professional advice may be appropriate.
❓ Why does the review date matter?
Crypto regulation and tax guidance change quickly, so legal claims should be checked against current primary sources.
❓ Should a vendor or dashboard be treated as an authority?
No. Vendor outputs are evidence inputs; legal and tax conclusions should be grounded in applicable law and regulator or tax-authority guidance.
❓ What should I do when jurisdictions conflict?
Identify every relevant jurisdiction and obtain qualified advice rather than assuming one country's rules control globally.
Summary
The UK crypto regulatory perimeter is layered rather than a single licence. As at 22 August 2026, in-scope UK cryptoasset businesses still need FCA registration under the Money Laundering Regulations (MLRs) for relevant exchange/custodian activities, while qualifying crypto promotions to UK consumers are subject to the financial-promotion regime. A new FSMA authorisation regime for regulated cryptoasset activities is scheduled to start on 25 October 2027. The disciplined approach is to separate labels from legal classification, record jurisdiction and date, preserve evidence, and verify current primary sources before acting.
