An AML analyst at a financial institution is examining an alert generated by the automated transaction monitoring system to determine whether the alert should be escalated to the AML unit for further investigation or whether it can be archived as a false positive. Which action might be reasonable for the AML analyst to take?

While ensuring the monitoring system is functioning correctly is important, this action does not directly address the specific alert in question. The analyst's immediate focus should be on evaluating the individual transaction or client behavior that triggered the alert, rather than testing the system's overall performance.

Restricting account access is a significant action that should only be taken after a thorough investigation has confirmed suspicious activity. Prematurely limiting a client's access may lead to unnecessary disruption and could damage the client relationship without adequate justification.

While obtaining information from the counterparty bank may be useful in some contexts, it is often more effective to first gather insights from the relationship manager who has a deeper understanding of the client. This initial step can clarify the situation before escalating inquiries to external parties.
