UK vs. EU Crypto Licensing
How the UK's new FSMA-based cryptoasset regime actually differs from the EU's MiCA CASP authorisation -- passporting, transition timing, and who regulates what.
This compares the structural design of the UK's new cryptoasset regime against the EU's MiCA framework for crypto business licensing specifically -- not personal tax treatment (see Kaavon's own /crypto-tax pages for that), and not a claim that either regime is "better." It draws on Kaavon's own directly-researched licensing sections for the United Kingdom and Ireland (as MiCA's directly-researched EU example) -- see each country's own crypto tax guide for full sourcing.

| Dimension | United Kingdom | European Union (MiCA) |
|---|---|---|
| Core mechanism | A new FSMA-based authorisation regime (Cryptoassets Regulations 2026) for named regulated activities, replacing reliance on Money Laundering Regulations registration. | MiCA's CASP (Crypto-Asset Service Provider) authorisation, granted by a national competent authority (e.g. the Central Bank of Ireland) under EU-wide rules. |
| Cross-border reach once authorised | UK authorisation covers UK operation only -- no automatic reach into the EU or elsewhere. | Generally passportable across all EU member states via a notification process (MiCA Articles 59/63/65), without a fresh full application in each one. |
| Who grants authorisation | The Financial Conduct Authority (FCA), a single national regulator. | Any EU member state's own national competent authority -- which one depends on the firm's choice. |
| Key 2026 timing | Cryptoassets Regulations 2026 passed by Parliament 4 February 2026; full scope of regulated activities expands from 25 October 2027. | MiCAR applied to CASPs from 30 December 2024, with each member state running its own national transitional period for pre-existing VASPs (Ireland's own ran 12 months, ending 29 December 2025). |
| Stablecoin issuance oversight | A distinct policy statement (PS26/10) jointly involving the Bank of England specifically for systemic stablecoins, separate from general cryptoasset-activity rules. | A separate MiCA applicability track for Asset-Referenced Token/E-Money Token issuers, applicable six months earlier (30 June 2024) than CASP authorisation itself. |
| DeFi treatment | The FCA's own stated position: rules apply to DeFi firms "where there is an identifiable controlling entity." | Not independently confirmed for this comparison -- MiCA's own text on DeFi specifically wasn't directly researched in this pass. |
United Kingdom vs. European Union (MiCA)
Why this comparison exists
The UK's departure from the EU means it builds its own, separate cryptoasset regime rather than adopting MiCA -- a live, current example of two major, economically significant jurisdictions solving the same basic problem (licensing crypto businesses) with structurally different mechanisms. The most consequential practical difference isn't which rules are stricter; it's that MiCA authorisation can reach the whole EU through one process, while UK authorisation reaches only the UK.
The passporting difference is the biggest practical one
A firm authorised as a CASP in one EU member state can generally extend its authorised services into other member states via a notification process, rather than a fresh full application in each one. A UK-authorised firm gets no equivalent automatic reach into the EU, and an EU-authorised CASP gets no automatic reach into the UK -- a business operating across both markets needs two separate authorisations under two genuinely different regimes, not one that happens to satisfy both.
Both regimes are still mid-transition in 2026, not fully mature
Neither regime should be treated as a finished, stable target. The UK's full regulated-activity scope doesn't expand until 25 October 2027, and MiCA's own national transitional periods only recently closed across EU member states (with some, like Ireland's, ending as recently as December 2025). A business researching either regime in 2026 is researching something still actively taking shape, not a settled system.
Who each may suit
This is general education, not a recommendation, and it does not rank either jurisdiction. A business whose target market is overwhelmingly UK-based has less practical need for EU-wide passporting; a business targeting multiple EU markets simultaneously gets more structural value from a single MiCA CASP authorisation than from separate national UK and EU-member-state processes. Many firms serving both markets pursue both authorisations rather than treating this as an either-or choice.
Key risks and limitations
- This comparison is based on Kaavon's own UK and Ireland research specifically -- it does not claim every EU member state implements MiCA's transitional provisions identically; national timing and specific national competent authority processes genuinely differ (see Kaavon's Global Crypto Licensing Directory for other EU states).
- MiCA's own DeFi-specific text was not independently researched for this comparison -- the DeFi row above reflects only what Kaavon has directly confirmed for the UK specifically.
- Fee and capital requirement figures are not compared here, since Kaavon's research did not independently verify comparable figures for both regimes.
Conclusion
The UK and the EU are both building substantive, currently-maturing cryptoasset licensing regimes in 2026, but on structurally different models -- a single-jurisdiction FSMA-based authorisation versus an EU-wide, passportable CASP authorisation. The practical question for a specific business isn't which is "better" in the abstract, but which markets it actually needs to reach and whether one authorisation, two, or neither is the right fit.
