(2)The main challenge identified in respect of the application of the provisions of Directive (EU) 2015/849 that lay down obligations for obliged entities, is the lack of direct applicability of the rules set out in those provisions and a fragmented approach along national lines. Although those rules have existed and evolved over three decades, they are still implemented in a manner not fully consistent with the requirements of an integrated internal market. Therefore, it is necessary that rules on matters currently covered in Directive (EU) 2015/849 which could be directly applicable by the obliged entities concerned are addressed in a Regulation in order to achieve the desired uniformity of application.
