The UK market abuse framework is designed to protect market integrity and investor confidence by prohibiting insider dealing, unlawful disclosure of inside information and market manipulation. Although tokenised instruments introduce new technology layers, the substance of the activity determines whether conduct falls within the regime: a digital token representing an ownership interest or a debt obligation can attract the same prohibitions as traditional securities. Regulators expect firms operating trading venues, matching services or custodial arrangements to consider how market abuse obligations apply across on‑chain and off‑chain processes.
Operationally, tokenisation offers richer audit trails but also novel surveillance challenges. Complete and immutable transaction records on distributed ledgers can assist in reconstructing sequences of trades and ownership changes, provided platforms retain accessible and reconciled off‑chain records for identity and off‑ledger events. Firms should maintain insider lists, implement information barriers and have clear policies for handling potential inside information about issuers or underlying assets, with escalation pathways consistent with FCA guidance on market abuse.
Platforms and issuers must also consider disclosure timing and fair disclosure for tokenised issuances. Market participants should be able to identify when an issuer must make market‑moving announcements and how those announcements propagate to token markets. Where off‑chain events affect token values, there should be documented procedures to ensure timely public disclosure or controlled handling of inside information.
For retail investors in fractional digital shares, these rules matter because surveillance, insider controls and transparent disclosure are core elements of market fairness. When comparing platforms or offerings, retail holders should seek clear explanations of how market‑abuse controls, trade surveillance and insider list procedures are implemented for tokenised assets.
