What kind of alerts should a teller be trained to recognize for suspicious activity?

Tellers should be trained to recognize uncommon withdrawal patterns and large cash transactions as indicators of suspicious activity. These patterns may deviate significantly from a customer's usual banking behavior, raising potential red flags for money laundering or other illicit financial activities. For instance, if a customer who typically withdraws small amounts suddenly attempts to make a large cash withdrawal or engages in withdrawal patterns that are inconsistent with their account history, it could signify that they are attempting to hide the source of their funds or are involved in other questionable activities. Identifying these patterns is crucial for maintaining financial security and adhering to regulatory compliance in banking practices.
