List of banks in Finland

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

European banking supervision distinguishes between significant institutions (SIs) and less significant institutions (LSIs), with SI/LSI designations updated regularly by the European Central Bank (ECB). Significant institutions are directly supervised by the ECB using joint supervisory teams that involve the national competent authorities (NCAs) 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.^[1] In Finland's case, the NCA is the Finnish Financial Supervisory Authority.^[2]

As of 1 September 2025, the ECB had four Finnish banking groups in its list of significant institutions:^[3]

• the Finnish branch of Danske Bank
• Kuntarahoitus, a public bank
• Nordea
• OP Financial Group, a cooperative banking group

A study published in 2024 assessed that of these, OP had the largest volume of assets in Finland (€160 billion at end-2023), followed by Nordea (€137 billion), then Danske Bank (€50.6 billion) and Kuntarahoitus (€49.7 billion).^[4] Among SIs based in other euro area countries, Rabobank also operates in Finland via a subsidiary.^[3]

As of 1 September 2025, the ECB's list of supervised institutions included 68 Finnish LSIs, three of which were designated by the ECB as "high-impact" on the basis of several criteria including size:

• Aktia Bank Abp, originally a savings bank established in 1825
• Säästöpankkiliitto, central entity of the Säästöpankkiryhmä group of 14 independent savings banks
• S-Pankki Oy, a cooperative bank

The other 65 Finnish SIs divided into three groups, as follows.^[3]

The September 2025 list included 22 cooperative banks (Finnish: Osuuspankki and POP) and 16 savings banks (Finnish: Säästöpankki, Swedish: Sparbank).

22 Finnish LSIs in the list were branches, mostly of Swedish entities:

The Bank of Finland and Nordic Investment Bank, both based in Helsinki, are public credit institutions that do not hold a banking license under EU law.

Several former Finnish banks, defined as having been headquartered in the present-day territory of Finland, are documented on Wikipedia in English. They are listed below in chronological order of establishment.
