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

If the UK government's December 2025 announcement set the direction, the three consultation papers published by the Financial Conduct Authority provide the detail. Together, CP25/40, CP25/41, and CP25/42 form the most comprehensive regulatory blueprint for cryptoassets yet 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, the answer is almost all of them. Trading platforms, intermediaries, lending and borrowing services, staking providers, and even certain decentralised finance activities are 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 directly responds to the wave of crypto lending platform collapses in 2022-2023 and shows that the regulator has closely examined how and why parts of the industry failed.

CP25/41: Disclosure And Market Abuse

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

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

CP25/42: Prudential Requirements

The third paper defines the financial buffers that crypto firms must hold. Own funds requirements range from £75,000 to £750,000, depending on the activities undertaken, with additional capital adequacy standards and public disclosure obligations. These thresholds are designed to be meaningful without being prohibitive, although smaller firms may find the compliance costs difficult to absorb.

Critical Dates

The authorisation window opens in September 2026, with the full regime becoming effective on 25 October 2027. Firms currently operating under the temporary registration regime will need to apply for full FCA authorisation during this period. 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 market that exists today. The firms that manage the transition will be those that treat regulatory compliance not as an obstacle, but as a competitive advantage — a lesson traditional financial services learned decades ago.
