In addition to Article 13(1)(d), Article 18(2) of Directive (EU) 2015/849 also requires obliged entities 'to examine, as far as reasonably possible, the background and purpose of all complex and unusually large transactions, and all unusual patters of transactions, which ahve no apparent economic or lawful purpose. In particular, obliged entities shall increase the degree and nature of monitoring of the business relationship, in order to determine whether those transactions or activities appear suspicious'. Moreover, Article 35(1) of the same Directive sets out an obligation on the part of obliged entities 'to refrain from carrying out transactions which they know or suspect to be related to proceeds of criminal activity or to terrorist financing until they have completed the necessary action in accordance with point (a) of the first subparagraph of Article 35(1) and have complied with any further specific instructions from the FIU or the competent authorities in accordance with the law of the relevant Member State'.

GL 4.74 of the EBA’s Risk Factor Guidelines sets out that ‘[f]irms should in any case determine which transactions they will monitor in real time, and which transactions they will monitor ex-post. As part of this, firms should determine: i. which high-risk factors, or combination of high-risk factors, will always trigger real-time monitoring; and ii. which transactions associated with higher ML/TF risk are monitored in real time, in particular those where the risk associated with the business relationship is already increased’.

Article 7(2) of Regulation (EU) 2015/847 requires recipients of payments ‘to implement effective procedures, including, where appropriate, ex-post monitoring or real-time monitoring’ to detect payment transactions that are not accompanied with the information required in terms of the same Regulation. GL 28 of the Joint Guidelines under Article 25 of Regulation (EU) 2015/847 on the measures payment service providers should take to detect missing or incomplete information on the payer or the payee, and the procedures they should put in place to manage a transfer of funds lacking the required information sets out that ‘PSPs and IPSPs should determine which high-risk factors, or combination of high-risk factors, will always trigger real-time monitoring, and which will trigger a targeted ex-post review. In cases of specific concern, transfers of funds should always be monitored in real time’.
