List of banks in Spain


The following list of banks in Spain is to be understood within the framework of the European single market and European banking union, which means that Spain's banking system is more open to cross-border banking operations than peers outside of the EU.

Policy framework

European banking supervision distinguishes between significant institutions and less significant institutions, with SI/LSI designations updated regularly by the European Central Bank. Significant institutions are directly supervised by the ECB using joint supervisory teams that involve the national competent authorities of individual participating countries. Less significant institutions are supervised by the relevant NCA on a day-to-day basis, under the supervisory oversight of the ECB. In the Spanish case, the NCA is the Bank of Spain.

Significant institutions

As of, the list of supervised institutions maintained by the ECB included the following ten Spanish banking groups as SIs, with names as indicated by the ECB for each group's consolidating entity. Of these, Santander has been consistently designated as Global systemically important bank by the Financial Stability Board, including in its update of November 2025.
A study published in 2024 assessed that the bank with most aggregate assets in Spain as of end-2023 was CaixaBank at €569 billion, followed by Santander, BBVA, Sabadell, Bankinter, Unicaja, Abanca, Kutxabank, Cajamar, Ibercaja, ING, and Deutsche Bank. Other euro-area banks with subsidiaries in Spain include BNP Paribas, Crédit Agricole, and Banca Mediolanum.
