Inside the FCA's Crypto Consultation Trilogy: A Practical Guide

If the UK government's December 2025 announcement was the headline, the three consultation papers published by the Financial Conduct Authority set out the detail. Together, CP25/40, CP25/41, and CP25/42 form the most detailed regulatory blueprint for cryptoassets ever produced by a major financial regulator — and firms operating in the UK market need to understand what they contain.

CP25/40: The Activities Framework

The first paper addresses the broadest question: which crypto activities will require FCA authorisation? In practice, almost all of them. Trading platforms, intermediaries, lending and borrowing services, staking providers, and even certain decentralised finance activities fall within scope. Larger platforms — those exceeding £10 million in annual average revenue — will face additional obligations, including non-discriminatory access rules and enhanced transparency requirements.

For retail lending, the FCA proposes mandatory over-collateralisation requirements. This is a direct response to the wave of crypto lending platform collapses in 2022-2023, and shows that the regulator has closely examined where the industry has failed.

CP25/41: Disclosure and Market Abuse

The second paper introduces requirements that will be familiar to anyone with experience in traditional securities markets. Issuers seeking admission to UK trading platforms must produce qualifying cryptoasset disclosure documents — essentially prospectuses — including a two-page summary of principal risks. The market abuse regime prohibits insider dealing and market manipulation, with large platforms required to monitor on-chain activity for suspicious patterns.

This is where the regulation becomes genuinely novel. Monitoring on-chain activity for market abuse is a technical challenge with no direct precedent in traditional finance. The FCA is effectively requiring platforms to build blockchain analytics capabilities that go well beyond current industry standards.

CP25/42: Prudential Requirements

The third paper sets out the financial buffers that crypto firms must maintain. Own funds requirements range from £75,000 to £750,000 depending on the activities undertaken, alongside additional capital adequacy standards and public disclosure obligations. These figures are designed to be meaningful without being prohibitive — although smaller firms may find the compliance costs challenging.

Critical Dates

The authorisation window opens in September 2026, with the full regime taking effect on 25 October 2027. Firms currently operating under the temporary registration regime will need to apply for full FCA authorisation within this window. Consultation responses were due by February 2026, and the FCA is expected to publish its final rules by mid-2026.

For investors and market participants, the practical takeaway is clear: the UK crypto market in 2027 will look fundamentally different from the one that exists today. The firms that navigate the transition successfully will be those that treat regulatory compliance not as an obstacle, but as a competitive advantage — the same lesson traditional financial services learned decades ago.
