These will include guidance on what is considered to be unusual or suspicious and give examples thereof. The policies and procedures shall include appropriate monitoring of the Correspondent Bank's activity, incorporating due diligence results such as customer risk rating and other factors considered meaningful in the assessment of transaction activity risk. In turn, the results of suspicious activity monitoring shall be factored into the periodic review of the client's file, particularly when the results of transaction monitoring indicate elevated risk levels.
