(5)Directive 2013/36/EU sets out five categories measuring systemic significance, which consist of quantifiable indicators. In order to minimise the administrative burden for institutions and authorities, those categories are identical to those applied by the Basel Committee on Banking Supervision. In further defining the quantifiable indicators, this Regulation should follow the same approach. The indicators should be chosen to reflect the different aspects of potential negative externalities of an entity's failure and its critical functions for the stability of the financial system. The reference system for assessing systemic significance should be the global financial markets and the global economy.
