I am emphasizing on this issue because banks need to be sensitive to the possibility of regulatory strictures / penalties for non-compliance. Consistent monitoring of transactions is necessary to prevent money muling.
A few banks in the past have already been fined for deficiencies in adherence to KYC/AML norms and with our commitment to comply with the FATF norms; I can only forewarn you that the frequency and severity of such penalties would rise in future.
