(21)A centralised application of the resolution rules for institutions laid down in Directive 2014/59/EU by a single Union resolution authority in the participating Member States can be ensured only where the rules governing the establishment and functioning of the SRM are directly applicable in the Member States to avoid divergent interpretations across the Member States. Such direct applicability should bring benefits to the internal market as a whole because it will contribute to ensuring fair competition and to preventing obstacles to the free exercise of fundamental freedoms not only in the participating Member States but in the internal market as a whole.
