(24)In addition to a capital conservation buffer and a countercyclical capital buffer, Member States should be able to require certain institutions to hold a systemic risk buffer in order to prevent and mitigate macroprudential or systemic risks not covered by Regulation (EU) No 575/2013 and by Directive 2013/36/EU, namely a risk of disruption to the financial system with the potential for serious negative consequences for the financial system and the real economy in a specific Member State. The systemic risk buffer rate should apply to all exposures or to a subset of exposures and to all institutions, or to one or more subsets of those institutions, where the institutions exhibit similar risk profiles in their business activities.
