UK FCA Proposes New DeFi Guidance as Crypto Regulation Takes Shape
The UK Financial Conduct Authority has launched a consultation on decentralised finance guidance, focusing on operational resilience, financial crime, and compliance as the country prepares for a broader cryptoasset regulatory regime.
The United Kingdom is taking another step toward clarifying how financial regulation applies to decentralised finance (DeFi). On October 21, 2026, the Financial Conduct Authority (FCA) opened a consultation on proposed guidance to help regulated firms manage the risks of using DeFi technologies in financial services.
The consultation comes as the UK prepares to introduce a broader regulatory framework for cryptoasset businesses. Alongside the DeFi guidance, the FCA has also opened a separate consultation addressing exclusions from cryptoasset regulation following recent legislative changes.
The latest developments could provide greater clarity for crypto businesses, financial institutions and technology providers seeking to operate within the UK’s evolving digital asset ecosystem.

FCA Consultation Focuses on DeFi Compliance and Risk Management
The FCA’s consultation, published under reference GC26/7, aims to explain how existing regulatory requirements apply to firms providing financial services through decentralised finance.
Rather than introducing an entirely new regulatory policy, the proposed guidance seeks to clarify how firms should approach existing obligations relating to operational resilience, financial crime prevention and money laundering.
DeFi uses blockchain technology and smart contracts to facilitate financial activities, potentially reducing reliance on traditional intermediaries. However, its decentralised and automated nature can create challenges when firms assess risks, maintain oversight and demonstrate regulatory compliance.
According to the FCA, businesses using DeFi should manage these risks responsibly, just as they would when adopting other technologies in financial services.
The regulator is inviting industry participants and other stakeholders to provide feedback before finalising the guidance.
What Risks Is the FCA Addressing?
The proposed guidance highlights several areas that regulated firms should consider when using or interacting with DeFi platforms and protocols.
1. Operational resilience
DeFi applications often rely on smart contracts, blockchain networks and interconnected technical infrastructure. Vulnerabilities in these components can disrupt services, expose assets to loss or affect the availability of financial products.
The FCA’s proposed guidance encourages firms to consider operational risks when designing and managing their DeFi-related activities. Businesses may need to assess their technology dependencies, identify potential points of failure and develop appropriate controls to address disruptions.
2. Financial crime and money laundering
DeFi platforms can enable transactions between users without the same traditional intermediary structure found in conventional financial services. This can make it challenging to identify suspicious activity and assess exposure to illicit financial flows.
The FCA is therefore focusing on how firms can manage financial-crime risks when using decentralised technologies.
Relevant considerations may include risk assessment, transaction monitoring, customer due diligence where applicable, and controls proportionate to the firm’s activities and legal obligations.
The guidance is intended to help firms understand how their existing responsibilities apply in a DeFi environment.
3. Governance and oversight
The use of decentralised protocols does not automatically remove the regulatory responsibilities of firms that incorporate them into financial services.
Businesses may need to examine who controls key functions, how decisions are made, which third-party technologies are involved and how risks are monitored.
The appropriate approach will depend on the firm’s activities, the relevant regulatory requirements and the structure of its relationship with the DeFi protocol.
Which Businesses Could Be Affected?
The proposed guidance is primarily aimed at FCA-regulated firms providing financial services using DeFi and falling within relevant operational resilience, compliance and financial-crime requirements.
It may also be relevant to firms preparing to enter the UK’s regulated cryptoasset market, businesses interacting with decentralised protocols, professional advisers and industry associations.
Potentially affected activities include financial services that use smart contracts, blockchain-based financial infrastructure or decentralised applications as part of their operating models.
However, the consultation does not mean that every DeFi protocol, developer or technology provider automatically falls under the same requirements. Regulatory obligations depend on the nature of the activity and the applicable legal framework.
Businesses should therefore assess their individual circumstances rather than assume that decentralisation alone either creates or removes a regulatory obligation.
Separate FCA Consultation Addresses Cryptoasset Regulatory Exclusions
The DeFi guidance consultation is part of a wider effort to clarify the UK’s future cryptoasset regulatory framework.
On October 21, the FCA also published Consultation Paper CP26/36, which addresses proposed guidance on exclusions from cryptoasset regulation following recent legislative amendments.
These changes cover specific arrangements and activities, including certain temporary settlement arrangements, qualifying stablecoin-related arrangements, proprietary trading and some technical services connected with third-party services or decentralised protocols.
The purpose is to help businesses understand when their activities may fall outside the scope of regulated cryptoasset activities and when FCA authorisation may be required.
The distinction is important for companies developing blockchain infrastructure, offering cryptoasset services or building products that interact with decentralised protocols.
Both consultations are open for feedback until November 18, 2026. The FCA plans to publish final guidance in January 2027.
UK Cryptoasset Regulatory Regime: Key Dates
The new DeFi consultation also arrives as the UK moves closer to implementing its wider cryptoasset regulatory regime.
Key dates include:
- September 30, 2026: The FCA opened the authorisation application period for firms preparing for the new cryptoasset regime.
- October 21, 2026: The FCA launched consultations on DeFi guidance and cryptoasset regulatory exclusions.
- November 18, 2026: Deadline for responses to both consultations.
- January 2027: The FCA plans to publish final guidance following consideration of consultation feedback.
- February 28, 2027: Deadline for existing UK crypto businesses seeking to use the relevant application-period arrangements to apply for authorisation.
- October 25, 2027: The new cryptoasset regulatory regime is scheduled to come into force.
Businesses operating in the UK crypto market should review the relevant FCA publications and determine whether their activities will require authorisation under the forthcoming framework.
What the Proposed Guidance Means for the DeFi Industry
The FCA’s latest initiative highlights a growing regulatory focus on how decentralised technologies are used within financial services.
For DeFi businesses and traditional financial institutions, clearer guidance could help reduce uncertainty around compliance expectations. Firms may be better positioned to evaluate technology risks, strengthen internal controls and determine how decentralised infrastructure fits into their regulated operations.
The consultation could also encourage closer cooperation between compliance teams, developers, cybersecurity specialists and risk managers.
At the same time, the industry’s response will be important. DeFi operates across interconnected blockchain networks, and regulatory expectations need to account for different business models and levels of control. Requirements that are unclear or difficult to apply could create challenges for responsible innovation, while proportionate guidance may help firms manage risks more effectively.
The consultation process allows industry participants to explain how the proposed approach would work in practice.
Conclusion
The UK’s latest FCA consultation represents another step in defining how decentralised finance fits within the country’s financial regulatory framework. By focusing on operational resilience, financial crime and existing compliance obligations, the regulator aims to help firms use DeFi technologies more responsibly.
The proposals should be viewed alongside the UK’s wider preparations for cryptoasset regulation, which are scheduled to take effect on October 25, 2027.
For crypto businesses, financial institutions and DeFi developers, the immediate priority is to understand the proposed guidance, assess potential regulatory implications and monitor the FCA’s next steps as the consultation process progresses.
