The compliance officer should report the suspicious activity to the Board of Directors, as they are ultimately responsible for the bank’s compliance program and oversight.The Board should be informed of the potential conflict of interest and reputational risk involved in the case, as well as the steps taken by the compliance officer to investigate and file the suspicious transaction report. The compliance officer should not prevent the filing of the report, as this would violate the legal obligations of the bank and expose it to regulatory sanctions and penalties. The compliance officer should not ask the Board member to explain the transaction, as this could compromise the integrity and independence of the investigation and the reporting process. The compliance officer should not maintain standard summary statistical reporting to the Board, as this would not adequately address the seriousness and complexity of the case.
