UK DeFi access through regulated platforms is at the center of a policy disagreement ahead of the country’s expanded cryptoasset regime on October 25, 2027. In an October 22, 2026 opinion article, Coinbase’s European policy head Katie Harries warned that execution requirements could effectively block those connections. The Financial Conduct Authority’s published position describes case-by-case oversight and planned guidance, rather than an explicit blanket ban.
Key Takeaways
- Harries argues that authorized-venue requirements could prevent regulated platforms from connecting customers to decentralized protocols.
- The FCA says its rules apply to DeFi firms with an identifiable controlling entity and plans tailored guidance.
- The broader cryptoasset regulatory perimeter is scheduled to expand on October 25, 2027.

Why UK DeFi access is contested
The dispute concerns regulated gateways into decentralized finance, not whether people can use open protocols directly. DeFi uses software to support activities such as borrowing, lending and trading without a conventional bank or broker handling the transaction.
Harries argues that requiring regulated platforms to execute customer orders only on FCA-authorized venues creates a practical obstacle: a decentralized protocol may have no person or entity capable of obtaining authorization. In her assessment, applying centralized trading requirements to these integrations could amount to a de facto ban.
That is a policy warning from a Coinbase executive, not an established regulatory outcome. Harries acknowledges that no rule explicitly prohibits firms from offering DeFi integrations.

What the FCA has confirmed
The FCA’s cryptoasset regime policy overview sets out final rules and guidance across regulated activities. It says the regime rests on regulations passed by Parliament on February 4, 2026, with the full scope of regulated activities expanding from October 25, 2027.
For DeFi, the regulator says its rules and guidance apply where there is an identifiable controlling entity, consistent with the Treasury-defined perimeter. It will assess scope case by case and consult on tailored guidance, including objective indicators of decentralization.
The FCA also identifies operational resilience and financial crime as areas for that guidance, while saying it wants to avoid overly prescriptive rules that could hinder innovation. This establishes the regulator’s stated approach, but does not settle every question about how an authorized intermediary may connect customers to a decentralized protocol.
The proposed alternative: supervise the gateway
Harries proposes focusing obligations on the regulated platform providing access. Such firms could explain when customers are leaving a regulated environment, obtain consent, assess selected protocols and report incidents and usage to supervisors.
Her argument addresses three concerns identified in the debate: customers misunderstanding their protections, firms using integrations to avoid obligations, and financial crime or market-resilience risks. She contends that excluding regulated gateways could instead push activity outside the FCA’s practical visibility.
These measures are her proposed approach, not confirmed requirements for all DeFi integrations. The practical distinction is between supervising an intermediary’s conduct and determining whether the underlying protocol itself falls within the regulatory perimeter.
Conclusion
The next policy step to watch is the FCA’s planned consultation on tailored DeFi guidance. Its treatment of scope and intermediary responsibilities will help clarify the access questions Harries has raised ahead of the October 2027 expansion.
