The following list of banks in Slovenia is to be understood within the framework of the European single market and European banking union, which means that Slovenia's 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 Slovenia's case, the NCA is the Bank of Slovenia. [2]

[4] : 29 Austria-based Addiko Bank and Erste Group also operate in Slovenia through subsidiaries, the latter via Banka Sparkasse, whereas BKS Bank operates in the country via a branch. [3]
As of 1 September 2025, the ECB's list of supervised institutions included four following Slovene LSIs, three of which are independent savings bank (Slovene : hranilnica). Of these, only Delavska Hranilnica was designated by the ECB as "high-impact" on the basis of several criteria including size. [3]
The Bank of Slovenia and Slovenian Export and Development Bank are public credit institutions that do not hold a banking license under EU law. [5]
