(2)In order to contribute to the objectives of the capital markets union, it is necessary, for the efficient use of CCPs, to address certain impediments to the use of central clearing in Directive 2009/65/EC and to provide clarifications in Directives 2013/36/EUnote and (EU) 2019/2034note of the European Parliament and of the Council. The excessive reliance of the Union financial system on systemically important third-country CCPs (Tier 2 CCPs) could pose financial stability concerns that need to be addressed appropriately. In order to ensure financial stability in the Union and to adequately mitigate potential risks of contagion across the Union financial system, appropriate measures should therefore be introduced to foster the identification, management and monitoring of concentration risk arising from exposures towards CCPs. In that context, Directives 2013/36/EU and (EU) 2019/2034 should be amended to encourage institutions and investment firms to take the necessary steps to adapt their business models to ensure consistency with the new requirements for clearing introduced by the amendments to Regulation (EU) No 648/2012 contained in Regulation (EU) 2024/2987 of the European Parliament and of the Councilnote and to enhance overall their risk management practices, also having regard to the nature, scope and complexity of their market activities. While competent authorities already have a comprehensive set of supervisory measures and powers to address deficiencies in the risk management practices of institutions and investment firms, including the requirement to have additional own funds for risks that are not, or not adequately, covered by the existing capital requirements, that set of supervisory measures and powers should be enhanced with additional, more specific tools and powers under Pillar 2 in the context of excessive concentration risk arising from exposures towards CCPs.
