CSSF Regulation No 25-05 concerning systemically important institutions authorised in Luxembourg
The Commission de Surveillance du Secteur Financier issued Regulation No 25-05 to identify six institutions as other systemically important institutions (O-SIIs) and set their additional capital buffers. The regulation mandates buffer rates ranging from 0.50% to 1.00% for Banque et Caisse d’Épargne de l’État, Banque Internationale à Luxembourg, BGL BNP Paribas, Clearstream Banking S.A., Intesa Sanpaolo Bank Luxembourg S.A., and Société Générale Luxembourg. These requirements enter into force on 1 January 2026, replacing the previous regulation and applying at the highest consolidation level.
