Which activity would likely raise a red flag for money laundering during account management?

The activity that would likely raise a red flag for money laundering during account management is consistent large cash transactions without explanation. This pattern is concerning because money laundering often involves converting illicitly obtained cash into seemingly legitimate funds. When individuals engage in frequent large cash transactions, especially without providing a clear or legitimate purpose, it suggests potential attempts to obscure the source of the funds.

In money laundering schemes, individuals commonly use cash transactions to avoid detection because cash doesn't leave a traceable paper trail like electronic transactions do. If large sums of money are deposited or withdrawn consistently without a valid reason, it raises suspicion among financial institutions and alerts them to the possibility of illicit activity, triggering further investigation.

The other activities—clients asking for higher withdrawal limits, frequent deposits of checks in varying amounts, and clients requesting additional account confidentiality—could also be suspicious but do not inherently signify money laundering as directly as consistent large cash transactions. They may pertain to customers’ legitimate needs or preferences and typically require further context to assess their risk effectively.
