The UK’s new crypto regime will extend FCA oversight to many overseas firms, reshaping how they access and serve UK customers.
The UK is moving rapidly towards a comprehensive regulatory framework for cryptoassets—and the implications for overseas firms are significant. With the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2025 approaching full commencement, firms based outside the UK can no longer assume that geography alone keeps them outside UK regulatory scope.
A defining feature of the UK’s emerging crypto regime is its extraterritorial reach. Any firm carrying on regulated cryptoasset activities “by way of business” for UK consumers may be required to obtain authorisation from the Financial Conduct Authority (FCA), even if it operates entirely offshore. As regulators sharpen their focus on consumer protection and market integrity, overseas firms must take a careful, proactive approach to understanding how—and whether—the UK rules apply to them.
A broader regulatory perimeter
The new regime significantly expands the range of crypto-related activities brought within regulation. These include operating cryptoasset trading platforms, safeguarding cryptoassets, dealing or arranging transactions, and certain staking and settlement activities. Importantly, the traditional “overseas persons” exclusion does not apply in the same way, meaning firms cannot rely on being offshore to avoid authorisation where UK retail clients are involved.
By contrast, overseas firms serving only UK institutional clients may, in some circumstances, fall outside the authorisation requirement—but this depends heavily on client structure, distribution chains, and whether those institutions act as intermediaries for retail consumers. The analysis is rarely straightforward.
Structural choices for overseas trading platforms
For overseas cryptoasset trading platforms (CATPs), the FCA has made clear that access to UK retail customers will require authorisation. In practice, this typically means choosing between establishing a UK subsidiary or operating through an authorised UK branch of an overseas entity. Each option carries different operational, governance, and compliance implications.
A UK subsidiary can offer clearer regulatory oversight and consumer recourse, but may involve additional cost and duplication of infrastructure. A branch model may allow greater integration with global trading and liquidity pools, but is subject to close scrutiny by the FCA and assessed on a case‑by‑case basis. Strategic decisions here must balance commercial objectives with supervisory expectations and long‑term regulatory resilience.
Stablecoins, intermediaries, and DeFi
The regime also draws important distinctions for stablecoin issuers, intermediaries, and decentralised finance (DeFi) projects. Issuing a qualifying stablecoin from overseas is not regulated in itself, but distributing it to UK consumers may trigger authorisation requirements—particularly where intermediaries are involved. UK‑issued stablecoins, by contrast, follow a different path, reflecting their closer alignment with domestic payments regulation.
For DeFi, the FCA’s focus is on control. Activities that are genuinely decentralised, with no identifiable controlling party, may fall outside the scope. However, where governance, influence, or consumer‑facing activity exists, regulatory scrutiny is likely to follow.
The case for early action
The risk for overseas firms is not just technical non‑compliance, but strategic misalignment. Failure to properly assess UK touchpoints could lead to enforcement action, forced exits from the UK market, and reputational damage. Conversely, early engagement with the UK framework may offer an advantage: alignment with UK standards could smooth access to other jurisdictions as global regulation converges.
With further FCA guidance and HM Treasury consultations ongoing, now is the time for overseas crypto businesses to carry out a granular, forward‑looking review of their models, structures, and growth plans. Those who act early will be best placed to access the UK market with confidence, build trust and operate effectively.
