UK FCA Opens DeFi and Crypto Regulation Consultations With Nov 18 Deadline

Two Consultations, One November Deadline

Britain's Financial Conduct Authority (FCA) opened two consultations on Wednesday that will decide how decentralized finance (DeFi) activity is brought inside the country's cryptoasset rules, and which parts of the market stay outside them. One paper asks how companies using DeFi can comply with the watchdog's standards; the other asks which crypto assets should sit outside regulation altogether. Feedback on both closes on Nov 18, and final guidance is planned for January 2027. Both papers went live on the FCA's website as formal guidance consultations, the mechanism the regulator uses to test draft rules with the industry. Nothing binds a firm until the FCA settles its final position next year.

The first paper, GC26-7, is a draft of the watchdog's DeFi guidance, and the consultation document frames its purpose narrowly. The proposed guidance, the FCA says, “seeks to clarify existing rules rather than establish new policy.” The practical work is compliance: companies operating in DeFi are asked how they meet the watchdog's requirements on money laundering and financial crime. Those rules already apply to UK cryptoasset businesses registered with the FCA, so the open question is how they map onto protocols with no central operator. The answer reaches well beyond the custodial crypto exchanges the anti-money-laundering framework was originally built around: teams behind decentralized applications (dapps), frontends and interface layers, across lending, trading and Bitcoin DeFi, would have to show which entity in a stack answers for customer due diligence, transaction monitoring and sanctions screening. Years of ambiguity over whether the frontend, the protocol or the treasury carries the legal duty is now being put to the market in writing. The FCA runs the papers through its standard guidance consultation process, testing draft text with industry before anything is finalized. Whoever the final text names as responsible registers, files and pays for compliance; whoever it exempts keeps operating outside.

Stablecoin Rules and the October 2027 Regime

The second paper, on exclusions from cryptoasset regulation, lands against a regime the FCA has already sketched. Earlier it revealed rules for cryptoasset firms that include stablecoin holding arrangements and reserve asset requirements, which the watchdog expects to enforce from October 2027. Reserve rules are, in practice, backing standards: providers of stablecoin holding arrangements must hold assets that match the balances customers own, so those balances can be honored on demand. The regime is no longer a draft in the way the consultations are: the FCA has set an enforcement date and opened the application book, accepting filings from crypto entities since Sept 30, with a Feb 28, 2027 deadline for companies seeking to be authorized under the rules. That sequencing gives a firm filing by late February 2027 months, not weeks, to complete the process before enforcement begins. The exclusions consultation will decide which activities never enter that pipeline at all, which is why it may matter as much as the guidance itself. For stablecoin issuers and custodial providers the path is mapped; for DeFi teams it is not, and the exclusions list will determine whether one is ever drawn for them. Industry response came the same day. The UK Cryptoasset Business Council welcomed the consultations while pressing the regulator on design. “DeFi sits among the most innovative parts of financial services,” the council wrote, arguing that the UK can still strike the right balance with “clear perimeter rules” and expectations that stay proportionate, and that a badly drawn boundary would push development out of the country. Its closing line to the FCA was direct: “the FCA needs to get this right.”

Three dates now anchor UK crypto compliance: Nov 18 for consultation responses, Feb 28, 2027 for authorization filings, and October 2027 for enforcement. The clarification-first stance lowers the relocation risk the business council flagged, since firms are being asked how they comply rather than whether they must. Clarity is also the entry ticket for traditional finance institutions that have waited for a defined perimeter before committing capital to UK crypto operations. The burden now sits with respondents: the exclusions and the final DeFi guidance will be written from comments the FCA receives over the next four weeks, and the firms that argue their case by Nov 18 will have helped shape the rules they must then follow.
