(10)Currently, credit purchasers and credit servicers cannot reap the benefits of the internal market due to barriers erected by divergent national regimes in the absence of a dedicated and coherent regulatory and supervisory regime. At present, there are no common Union standards for the regulation of credit servicers. In particular, no common standards have been set for the regulation of debt collection. Member States have very different rules for how credit purchasers are able to acquire credit agreements from credit institutions. Credit purchasers that purchase credit issued by credit institutions are not regulated in some Member States, while in others they are subject to various requirements, sometimes amounting to a requirement to obtain an authorisation as a credit institution. Those differences between regulatory requirements have resulted in considerable obstacles to legally purchasing credit cross-border in the Union, mainly by increasing the compliance costs faced when seeking to purchase credit portfolios. As a result, credit purchasers operate in a limited number of Member States, which has resulted in weak competition in the internal market as the number of interested credit purchasers remains low. That in turn has led to an inefficient secondary market for NPLs. In addition, the essentially national markets for NPLs tend to remain of a small volume.
