FCA outlined UK crypto disclosure and market-abuse framework

The UK Financial Conduct Authority published its first detailed blueprint for cryptoasset admissions, disclosures and market-abuse controls on December 16, 2024, moving the country’s regulatory debate from broad policy commitments toward the responsibilities of trading platforms, issuers and other market participants.

Discussion Paper DP24/4 was not a final rulebook. The FCA described it as its initial view and requested feedback through March 14, 2025. A formal consultation was expected only after the government laid the relevant statutory instruments. No firm received authorization, no token was approved, and no new conduct requirement took effect merely because the paper appeared.

That distinction was important because crypto remained largely unregulated in the UK on December 16 outside specific regimes, including anti-money-laundering registration and rules governing financial promotions. The paper nevertheless showed how substantially the regulatory perimeter could expand if Parliament and the FCA completed the proposed framework.

Trading platforms as gatekeepers

Under the admissions and disclosures model, admitting a cryptoasset to a regulated trading platform would trigger information requirements tailored to the asset. The FCA envisioned cryptoasset trading platforms conducting due diligence on the issuer, offeror or other person seeking admission and examining whether disclosures were true, complete and not misleading.

The proposed review could extend to the asset’s underlying distributed-ledger technology, smart contracts, available code audits and people associated with the project. Platforms could be required to publish a summary of the scope and principal findings of that work. The FCA also considered processes for rejecting assets presenting fraud, financial-crime or technological risks.

These ideas would place regulated platforms in a role closer to institutional market gatekeepers than neutral token catalogues. They would also create practical difficulties for decentralized assets whose original issuer was absent, unidentified or uninvolved in an exchange’s listing decision. The paper asked industry how responsibility should operate in those cases rather than claiming the problem was settled.

Adapting market-abuse rules to crypto

The proposed Market Abuse Regime for Cryptoassets drew from the UK’s existing securities framework but sought adaptations for digital assets. It contemplated prohibitions addressing insider dealing, unlawful disclosure of inside information and market manipulation.

Where an issuer requested admission, the FCA’s initial view was that the issuer should disclose relevant inside information promptly and broadly. Where no identifiable issuer participated, responsibility could fall to the person seeking admission—often the trading platform—but only for information concerning that person and reasonably known to it.

The paper also examined proportionate on-chain monitoring. Rather than requiring firms to scan every transaction associated with an asset, the FCA suggested high-level expectations under which platforms and intermediaries would maintain capabilities appropriate to their businesses. Such monitoring could connect suspicious exchange activity with transfers to private wallet addresses, while leaving implementation choices to supervised firms.

Information sharing across venues

A further proposal involved private information-sharing mechanisms among authorized platforms. If one platform detected suspected manipulation or removed a user for potentially abusive conduct, relevant information could help another platform assess the same activity. The FCA said shared information should not automatically require every participating venue to remove that user.

This reflected a defining market-structure problem: crypto trading and blockchain activity could be distributed across multiple venues and wallets, allowing suspicious conduct to escape a surveillance system limited to one order book. The FCA did not propose operating the information-sharing mechanism itself and acknowledged that privacy, data quality and governance required further work.

What December 16 established

The verified development was a regulatory design document, not enacted law. It mattered because it identified where the FCA expected accountability to sit: issuers for disclosures when they participated, platforms for admission controls and surveillance, and regulated firms collectively for detecting conduct spanning venues.

As of December 16, 2024, the costs, technical standards, statutory language and final scope remained unresolved. The central institutional signal was that the UK intended to treat crypto market integrity as a continuing disclosure and surveillance problem, not solely an anti-money-laundering or advertising issue.
