In a large US bank, an individual leads a team in charge of overseeing the governance and effectiveness of the bank's transaction monitoring approach. Which strategies should the team implement?

While reviewing suspicious activity reports (SARs) is important, the focus should be on the overall effectiveness of the transaction monitoring system rather than on withdrawing SARs. This strategy does not directly enhance governance or improve the detection of suspicious activities as it deals with post-reporting actions rather than proactive monitoring.

This choice is crucial since it emphasizes the need for continuous evaluation of the transaction monitoring scenarios in place. By aligning these scenarios with current AML typologies, the team can improve the system's effectiveness in detecting suspicious transactions, which is vital for compliance and risk management.

This strategy is also important as it fosters collaboration with the legal team to ensure that transactions under scrutiny are managed properly. This cooperation is key to compliance with legal requests and enhances the overall effectiveness of transaction monitoring by ensuring that legal guidelines are followed.

Although reviewing client profiles is essential for maintaining accurate risk assessments, this strategy focuses more on client due diligence rather than the broader governance of the transaction monitoring system. It supports AML efforts but does not directly assess the monitoring scenarios themselves.
