When should a financial institution file an STR?

• A. Whenever they are closing an account.
• B. Whenever they detect unusual or suspicious transactions.
• C. Only with established criminal violations.
• D. After Board of Directors approval.

Answer: (B)

A financial institution should file a Suspicious Transaction Report (STR) whenever it detects unusual or suspicious transactions. This requirement is a critical aspect of anti-money laundering (AML) compliance, as it enables institutions to report activities that might indicate money laundering, fraud, or other illicit activities.

Filing an STR upon identifying such transactions is in line with the regulatory expectations set forth by authorities to prevent and mitigate potential financial crimes. Institutions have a responsibility to monitor transactions and assess them against established criteria for suspicious behavior. By doing so, they contribute to the broader effort of maintaining the integrity of the financial system and assisting law enforcement in investigating potential criminal activity.

While other options might appear relevant in different contexts, they either misinterpret the timing or the conditions under which an STR should be filed. For instance, closing an account may be a necessary action, but it does not inherently necessitate an STR unless suspicious activity is identified. Similarly, filing only after a criminal violation is established or obtaining Board approval before filing are not requirements for STR submissions. Instead, the focus should be on the detection of suspicious activity as it occurs, which makes this response the appropriate action.
