BPCE (for Banque Populaire Caisse d'Epargne) is a major French banking group formed by the 2009 merger of two major retail banking groups, Groupe Caisse d'Épargne and Groupe Banque Populaire. As of 2025, it was France's third-largest bank, the sixth largest in Europe, and the twenty-first in the world by total assets.[3] It has more than 8,200 branches nationwide under their respective brand names serving nearly 150 million customers.[4] Its wholesale banking subsidiary Natixis, previously a separately listed company, was delisted and came under full ownership of Groupe BPCE in 2021.
BPCE has been designated as a Significant Institution since the entry into force of European Banking Supervision in late 2014, and as a consequence is directly supervised by the European Central Bank.[5][6] It is also designated as a global systemically important bank (G-SIB) by the Financial Stability Board.
