The Bank of Greece identified the other systemically important institutions (Other Systemically Important Institutions – O-SIIs) in Greece for 2026. Specifically, the following credit institutions were identified as O-SIIs on both a solo and consolidated basis: Alpha Bank S.A., National Bank of Greece S.A., Piraeus Bank S.A. and Eurobank S.A.
It also set the O-SII buffer rate for 2027 at 1.25% for Eurobank S.A. on a consolidated basis and at 1% for the following credit institutions: Alpha Bank S.A. on both a solo and consolidated basis, National Bank of Greece S.A. on both a solo and consolidated basis, Piraeus Bank S.A. on both a solo and consolidated basis, and Eurobank S.A. on a solo basis, effective from 1 January 2027.
The O-SII buffer rate for 2027 remains unchanged for each institution.
The methodology applied by the Bank of Greece to identify O-SIIs and set the O-SII buffer is set out in Executive Committee Act 221/1/17.10.2023 (Government Gazette, Series B, No. 6141).
Under this methodology, a score is calculated to indicate each institution’s systemic importance, based on specific criteria relating to its size; its importance to the economies of Greece and the European Union; the significance of its cross-border activities, including the complexity arising from those activities; and its degree of interconnectedness with the financial system. Mandatory indicators correspond to these four criteria and are used, at a minimum, to calculate each institution’s score, which is expressed in basis points (bps). Institutions with scores exceeding 350 bps (the scoring threshold) are considered O-SIIs because of their systemic importance.
