Market Abuse

Overview

Market abuse is conduct that undermines fair and orderly markets, including market manipulation, insider dealing, unlawful disclosure of inside information, and other deceptive or abusive trading behavior defined by applicable law.

Market Abuse is closely connected to Market Manipulation, Market Abuse Surveillance, and Layering (Market Manipulation). It is a legal and supervisory category rather than a single technique; individual patterns such as layering are examples that require context, evidence, and jurisdiction-specific analysis.

Operational implementation should establish surveillance coverage, retain orders and trades, identify related accounts, protect inside information, investigate alerts, document decisions, report suspicious activity where required, and govern model changes.

The principal failure modes include cross-venue blind spots, weak identity linkage, false positives, unmonitored decentralized activity, delayed escalation, incomplete order data, and inconsistent legal interpretation.

Useful measures include alert precision, investigation age, suspicious reports, recurring actors, coverage by venue and asset, and enforcement or remediation outcomes.

Operationally, teams should establish surveillance coverage, retain orders and trades, identify related accounts, and protect inside information. Key risks include cross-venue blind spots, weak identity linkage, false positives, and unmonitored decentralized activity.

A production treatment of Market Abuse should test the use of is conduct that undermines fair and orderly markets, including market manipulation, insider dealing, unlawful disclosure of inside information, and other deceptive or abusive trading behavior defined by applicable law within the relevant asset, decision, or service state. The Market Abuse context record for including market manipulation, insider dealing, and unlawful disclosure of inside information should preserve source data, configuration or policy version, responsible actor, exception, and outcome. Review of Market Abuse should determine whether safeguards addressing including market manipulation, insider dealing, and unlawful disclosure of inside information changed exposure in practice, not merely whether a document or setting existed.
