The UK needs a workable route to regulated DeFi access
The UK's proposed crypto rules, set to take effect in October 2027, risk creating a de facto ban on regulated firms providing access to decentralized finance (DeFi), according to Coinbase's European policy head.

The Financial Conduct Authority's (FCA) new crypto regulations, designed to ensure customer orders are executed on authorized venues, could inadvertently block regulated platforms from integrating with DeFi protocols. This is because DeFi's decentralized nature means there isn't a single entity to authorize, potentially hindering the UK's ambition to lead in digital assets.
Imagine a new kind of online playground where kids can swap toys directly without a grown-up watching over every trade. The UK government wants to make sure grown-ups are always there to keep things safe. But the rules they're making might accidentally stop the grown-ups from even letting kids into this new playground, even if they promise to watch from the side. Other countries are trying to find a way for grown-ups to help kids play safely in this new space.
Analysis
The United Kingdom is at a pivotal moment regarding its approach to decentralized finance (DeFi), with new regulations threatening to isolate its financial sector from a rapidly evolving technological landscape. Katie Harries, head of policy for Europe at Coinbase, argues that the Financial Conduct Authority's (FCA) proposed crypto rules, slated for implementation in October 2027, could inadvertently impose a de facto ban on regulated entities offering DeFi access. This situation arises because the FCA's framework requires customer orders to be executed on an authorized venue, a condition difficult for inherently decentralized protocols to meet, as they lack a central 'person' or entity for authorization. The implications extend beyond crypto enthusiasts, touching upon the future competitiveness of the City of London and the UK's capacity to shape the next generation of global financial infrastructure.
FCA's Proposed Rules
The core issue stems from the FCA's intention to apply existing rules for centralized trading to DeFi, rather than developing specific guidelines for these unique products. While the FCA aims to prevent overseas firms from illegally accessing the UK market and address concerns like consumer protection, financial crime, and market resilience, its current approach risks unintended consequences. The author contends that these legitimate risks should prompt the development of clear information for consumers and defined responsibilities for firms, rather than an outright prohibition. A de facto ban would not eliminate DeFi but rather push more activity into unregulated spaces, reducing the FCA's visibility and regulated firms' ability to guide customer interactions safely.
Regulated platforms, the article suggests, could serve as crucial points of supervision. They could clearly inform customers when they are transitioning from a regulated environment, require explicit consent for such transitions, and curate access to vetted protocols. Furthermore, these firms could assess operational and governance risks, and report incidents and usage data to regulators, thereby enhancing oversight rather than diminishing it. This approach aligns with how the UK already manages access to various financial products, from stocks to commodities, through regulated institutions that provide gateways to markets with differing levels of oversight.
October 2027
The deadline of October 2027 marks a critical juncture, as firms offering crypto services to UK customers will require FCA authorization. If the FCA's approach remains unchanged, regulated platforms may no longer be able to provide customers with access to DeFi services. This timeline directly challenges the government's stated ambition for the UK to "lead the world on digital assets." Cutting off British firms from the decentralized infrastructure that underpins digital asset markets would severely impede this goal. The full potential of on-chain tokenized finance, which relies on seamless interaction with decentralized technology, cannot be realized if confined to closed and fragmented systems.
European Union
In contrast to the UK's potentially restrictive stance, other major jurisdictions are actively exploring pathways for regulated DeFi innovation. The European Union, through the European Securities and Markets Authority (ESMA), has proposed allowing regulated firms to provide access to DeFi, recognizing its potential for innovation within a transparent and regulated environment. Similarly, the United States Securities and Exchange Commission (SEC) granted an "Innovation Exemption" for peer-to-peer trading of tokenized stocks using automated systems and liquidity pools. These examples demonstrate a global trend towards integrating traditional finance with DeFi infrastructure, rather than isolating them. The UK is urged to explore similar potentials before irrevocably closing off this option, ensuring it remains competitive and relevant in the evolving global financial landscape.
Key points
- The UK's proposed crypto rules, effective October 2027, risk a de facto ban on regulated firms accessing DeFi.
- The Financial Conduct Authority (FCA) requires customer orders on authorized venues, which decentralized protocols cannot meet.
- This approach could hinder the UK's ambition to lead in digital assets and push DeFi activity beyond regulatory visibility.
- Other jurisdictions like the EU and US are exploring ways to enable regulated DeFi innovation and integration.
- Regulated platforms could provide a supervised gateway to DeFi, offering consumer information and risk assessment, rather than a ban.
If the FCA re-evaluates its approach and creates a workable route for regulated firms to access DeFi, the UK could foster significant innovation, attract digital asset businesses, and integrate this technology safely into its financial system. This would allow the UK to fulfill its ambition of leading in the digital asset space, benefiting from the efficiencies and accessibility DeFi offers.
Should the current proposed rules remain unchanged, the UK risks stifling innovation in its financial sector, pushing DeFi activity into unregulated shadows, and losing its competitive edge to other jurisdictions like the EU and US. This could lead to a missed opportunity to shape the future of finance and a decline in the City of London's global standing in digital assets.
