Banca d'Italia Identifies O-SIIs and Sets Capital Buffer Requirements

Media Relations Division – Banca d’Italia e-mail: stampabi@bancaditalia.it Press Release By the Communications Directorate Rome, 27 February 2026 Identification of other systemically important institutions authorized to operate in Italy In its statement issued last November, and based on data as of the end of 2024, Banca d’Italia identified the banking groups Intesa Sanpaolo, UniCredit, Banco BPM, ICCREA and Banca Nazionale del Lavoro as Other Systemically Important Institutions (O-SIIs) authorized to operate in Italy. Starting from January 1, 2026, Intesa Sanpaolo, UniCredit, Banco BPM, ICCREA and Banca Nazionale del Lavoro are required to hold an O-SII capital buffer equal to 1.25, 1.25, 0.50, 0.25 and 0.25 per cent respectively of their total risk-weighted exposures. The identification procedure conducted last November was unable to consider the consolidation operations carried out last year involving the BPER Banca and Banca Popolare di Sondrio groups, as well as the Monte dei Paschi di Siena and Mediobanca groups, since the related identification procedure had been initiated before these transactions were completed. Once the aforementioned transactions had been completed, Banca d’Italia initiated a new procedure concerning the BPER Banca and Monte dei Paschi di Siena groups in their new forms. Both groups have been identified as O-SIIs authorized to operate in Italy and, starting from April 1 2026, they will be required to maintain an O-SII buffer equal to 0.50 per cent of their total risk-weighted exposures (see Table 1). Table 1 O-SII buffers (per cent) Banking group From 1 Jan. 2026 From 1 Apr. 2026 INTESA SANPAOLO 1.25 1.25 UNICREDIT 1.25 1.25 MONTE DEI PASCHI DI SIENA 0.00 0.50 BANCO BPM 0.50 0.50 BPER 0.25 0.50 ICCREA 0.25 0.25 BANCA NAZIONALE DEL LAVORO 0.25 0.25 The decision on the O-SII buffers was taken pursuant to Banca d’Italia’s Circular No. 285/2013 (prudential regulations for banks), which implements Directive 2013/36/EU and specifies the criteria on which the methodology for identifying O-SIIs is based. The assessment was conducted in accordance with the European Banking Authority Guidelines (EBA/GL/2014/10), which set out the criteria and data required to identify O-SIIs in EU Member States. The assessment covered all banking groups and stand-alone banks operating in Italy. For each bank/banking group, the identification considered the four categories established by the EBA guidelines, i.e. size, importance for the Italian economy, complexity and interconnectedness with the financial system.
