List of banks in Portugal

The following list of banks in Portugal is to be understood within the framework of the European single market and European banking union, which means that Portugal'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 Portugal's case, the NCA is the Bank of Portugal.

Significant institutions

As of, the list of supervised institutions maintained by the ECB included the following three Portuguese banking groups as SIs, with names as indicated by the ECB for each group's consolidating entity:

Banco Comercial Português SA
Caixa Geral de Depósitos SA
LSF Nani Investments Sàrl, holding entity of Novo Banco

Meanwhile LSF / Novo Banco has been acquired by BPCE, and other euro-area-based banking groups also have operations in Portugal. A study published in 2024 assessed that the bank with most aggregate assets in Portugal as of end-2023 was CGD at €99 billion, followed by BCP, Santander, Novo Banco, and CaixaBank. Other euro-area banking groups are unmentioned in this list because they operate in Portugal via a branch, such as BBVA, even though it also maintains a Portuguese subsidiary. The two other euro-area SIs that operate in Portugal via subsidiaries are Abanca and Crédit Agricole.

Less significant institutions

As of, the ECB's list of supervised institutions included 94 Portuguese LSIs.
