The followinglist of banks in Austria is to be understood within the framework of theEuropean single market andEuropean banking union, which means thatAustria's banking system is more open to cross-border banking operations than peers outside of the EU.
European banking supervision distinguishes betweensignificant institutions (SIs) andless significant institutions (LSIs), with SI/LSI designations updated regularly by theEuropean Central Bank (ECB). Significant institutions are directly supervised by the ECB using joint supervisory teams that involve thenational 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 Austria's case, the NCA is theFinancial Market Authority.[2]
As of 1 September 2025, the list of supervised institutions maintained by the ECB included the following seven Austrian banking groups as SIs, with names as indicated by the ECB for each group's consolidating entity.[5] Of these, four were part of the two Austrian IPSs.

278 of the LSIs in the ECB's list, including the six above-listed high-impact LSIs, were in the Raiffeisen IPS, which therefore represented nearly 86 percent of the total number of Austrian LSIs.[5]
The ECB's list of 1 September 2025 included 9 LSIs that were affiliates of financial groups outside the euro area, namely 2 branches and 7 subsidiaries:
