What are considered indicators of potential money laundering?

Large and frequent transactions are considered strong indicators of potential money laundering because they often represent attempts to obscure the origin of illicit funds. Money laundering typically involves moving money through various transactions to make it appear legitimate. When there are large transactions that occur frequently, especially if they do not align with the typical financial behavior of the account holder or business involved, it raises red flags for financial institutions and regulatory bodies.

This pattern can suggest that an individual or entity is trying to integrate illegal funds into the financial system. These transactions often intentionally involve complex structures and rapid movements to avoid detection by authorities. Monitoring for such activity allows banks and law enforcement to focus on potentially illicit financial behavior and take necessary actions to comply with anti-money laundering regulations.

The other options mentioned could have legitimate explanations or may not be strong indicators on their own without additional context, making them less conclusive compared to the clear flags raised by large and frequent transactions.
