The United Kingdom's crypto rules, set to take effect in October 2027, risk cutting regulated firms off from DeFi entirely. Katie Harries, Coinbase's head of policy for Europe, argues the Financial Conduct Authority's requirement that all customer orders route through FCA-authorized execution venues creates a structural barrier: DeFi protocols have no legal entity that can obtain authorization.
The FCA's mandate targets overseas firms illegally accessing UK markets. But by applying the same authorization requirement to decentralized exchanges and lending protocols as to centralized trading platforms, the regulator effectively forecloses compliant DeFi access.
"DeFi operates without a specific legal entity or person that could become an FCA-authorized venue," Harries said. Regulated platforms adhering to the rule would be unable to connect customers to these protocols.
The FCA has not explicitly banned DeFi integrations, but Harries describes the current regulatory stance as a de facto prohibition.
Other jurisdictions are moving in the opposite direction. The European Securities and Markets Authority proposed allowing regulated firms to provide DeFi access within a transparent framework. In the U.S. the Securities and Exchange Commission granted an "Innovation Exemption" for peer-to-peer trading of tokenized stocks, signaling regulatory willingness to accommodate decentralized financial structures.
The UK government has publicly stated its ambition to "lead the world on digital assets." Cutting British regulated providers from DeFi infrastructure—foundational to crypto markets—undermines that positioning relative to jurisdictions enabling compliant access.
