Monitoring & Reporting

Transaction Monitoring

Transaction Monitoring is the ongoing surveillance of customer transactions — in real time or in batch — to detect patterns and behaviours that may indicate money laundering, fraud, or other financial crime.
See Transaction Monitoring Back to Glossary

Transaction monitoring applies rules and machine-learning models to flag activity that deviates from a customer's expected behaviour or matches known laundering typologies such as structuring, layering, or rapid movement of funds. Flagged activity generates alerts for analyst review.

The central tension is detection versus noise: thresholds set too tightly bury teams in false positives, while loose thresholds miss real risk. Modern systems use risk scoring and AI to prioritise alerts and route them into a case-management workflow that can lead to a SAR.

Key points

  • Combines rules-based scenarios with machine-learning models
  • Detects typologies like structuring, layering, and smurfing
  • Feeds an alert-triage and case-management workflow
  • Calibrated continuously to balance detection and false positives

How One Constellation helps

Frequently asked

Does every alert lead to a SAR?+
No. An alert is only a signal that activity crossed a risk threshold. An analyst investigates, and a SAR is filed only where no legitimate explanation is found. Closed alerts are documented just as filed ones are.
