Daily Compliance Brief — Global Regulators Increase Focus on Effectiveness of Ongoing Transaction Monitoring Calibration

April 23, 2026

Signal

Regulators across multiple jurisdictions are increasing scrutiny on the calibration of transaction monitoring systems, particularly whether scenarios and thresholds are effectively aligned with current financial crime risks.

Recent observations highlight outdated scenario design, infrequent tuning cycles, and weak alignment between typologies and detection logic, raising concerns that emerging risks may not be adequately captured.

This reflects a broader expectation that monitoring frameworks remain dynamic, continuously adjusted to reflect evolving typologies, customer behavior, and external threat indicators.

Why it matters

Financial institutions should reassess scenario calibration frameworks, including threshold setting, typology mapping, and frequency of tuning activities.

Monitoring controls may require enhancement to ensure detection logic remains relevant, risk-based, and capable of identifying new or changing patterns of suspicious activity.

Compliance teams should also strengthen governance and validation processes to ensure ongoing monitoring effectiveness is measurable, documented, and aligned with regulatory expectations.
