Market Abuse Surveillance in Banks: Coverage, Data and Escalation
Market-abuse controls must identify suspicious orders and transactions across products, venues and channels. Surveillance is difficult because legitimate strategies can resemble abuse and relevant evidence is distributed across trading and communications systems.
Regulatory and risk context
Risk assessment should cover instruments, desks, clients, markets and behaviours such as insider dealing, manipulation and attempted abuse. Scenario coverage and thresholds need a documented connection to that risk universe.
Implementation architecture
Reconcile order and trade feeds, time synchronisation, reference data, trader identifiers and communications. Test alerts using known cases, simulations and below-threshold samples. Investigators need joined evidence and clear escalation standards.
Where programmes fail
Failures arise from missing cancelled orders, incorrect clocks, siloed asset classes, thresholds set to control workload and closures based on narrow alert data. Low alert rates can signal either low risk or poor coverage.
Board and senior-management evidence
Senior reporting should cover unmonitored risk, data exceptions, alert ageing, repeat subjects, suspicious reports, quality assurance and remediation. Governance must protect surveillance independence from commercial pressure.
Five-step control checklist
- Define the legal and regulatory scope.
- Assign accountable business and compliance owners.
- Map obligations to data, systems, procedures and evidence.
- Test design and operating effectiveness.
- Escalate limitations and verify remediation.
