UK Finalizes 2026 Crypto Regulatory Framework with DeFi Carve-Out

The United Kingdom is finalizing a comprehensive cryptoasset regulatory framework that will come into force on 25 October 2027, with HM Treasury's draft statutory instrument laid before Parliament in December 2025 creating new regulated activities under the Financial Services and Markets Act 2000. The regime grants the Financial Conduct Authority broad powers over crypto trading platforms, intermediaries, lending, staking, and decentralised finance, requiring UK authorization for most crypto activities targeting local consumers while allowing overseas firms serving only institutional clients to remain outside full authorization. The framework includes a DeFi carve-out for truly decentralised services with no identifiable operator, but the FCA will probe protocols for controlling entities and apply full supervision to large DeFi front-ends, DAOs with clear controllers, and protocol teams that set parameters and capture fees. The UK approach aligns with MiCA-style oversight and converges with global regulatory trends including U.S. efforts like the CLARITY Act, applying a same-risk, same-outcome philosophy to crypto rather than creating DeFi-specific regulatory silos.

UK cryptoasset regulatory framework timeline and scope

Treatment of decentralised finance and the 'truly decentralised' test

• ▪The Financial Conduct Authority will determine in any given case whether there is an identifiable controlling person conducting specified cryptoasset activities by way of business.
• ▪The Financial Conduct Authority plans to apply its rules to DeFi services if there is an identifiable controlling entity.
• ▪Large DeFi front-ends and DAOs with clear controllers are expected to be pulled into full UK Financial Conduct Authority supervision.
• ▪The Financial Conduct Authority will apply core requirements to decentralised finance where there is an identifiable controlling entity carrying on new regulated cryptoasset activities.
• ▪The Financial Conduct Authority does not propose a bespoke regime for decentralised finance.
• ▪The Financial Conduct Authority will probe DeFi protocols for any identifiable controlling entity.

Alignment with global crypto regulation trends

• ▪The Financial Conduct Authority applies a same risk, same regulatory outcome approach on operational resilience, financial crime and prudential requirements to DeFi.

Perspective of DeFi protocol developers

• ▪Truly decentralised DeFi projects without identifiable operators can continue serving UK users without Financial Conduct Authority authorization.

Perspective of Financial Conduct Authority

• ▪The Financial Conduct Authority will investigate DeFi protocols on a case-by-case basis to identify controlling persons conducting cryptoasset activities.
• ▪The Financial Conduct Authority rejected creating a separate regulatory framework specifically designed for decentralised finance protocols.

Perspective of Overseas crypto firms

• ▪Foreign cryptocurrency platforms targeting UK retail consumers will require authorization from a UK-based entity under the 2027 regime.

Perspective of HM Treasury

• ▪HM Treasury chose to regulate cryptoassets by creating new activities under the Financial Services and Markets Act 2000 rather than drafting separate crypto legislation.
• ▪HM Treasury's December 2025 statutory instrument establishes that truly decentralised activities with no business operator do not require authorization.
