Which operational situation might indicate that money laundering is occurring at or through a deposit-taking financial institution?

This choice correctly indicates a potential sign of money laundering. Criminals may prefer large-denomination bills to quickly move significant amounts of cash without triggering suspicion, making this demand a notable concern for financial institutions.

While maintaining a log of monetary instruments is good practice for tracking transactions, it does not directly indicate money laundering. This process is a standard procedure for compliance and record-keeping rather than a specific operational warning sign of illicit activity.

An increase in the adoption of digital products and services reflects positive growth and customer engagement, not necessarily a sign of money laundering. This trend can indicate a shift in consumer preferences towards convenience rather than illicit financial behaviors.

While rapid transaction services can be leveraged for money laundering, reduced settlement times alone do not indicate illicit activity. Many legitimate transactions benefit from faster processing times, and this choice lacks a direct correlation to money laundering risk.
