What changed
The NBS Bank Board formally adopted an NBS Decision establishing O-SII buffer rates applicable from 1 January 2027. Five domestic banks identified as systemically important institutions must hold capital buffers at specific percentages: Slovenská sporiteľňa (2.00%), Všeobecná úverová banka (1.75%), Tatra banka (1.50%), Československá obchodná banka (1.25%), and Prima banka (0.25%).
Banks designated as O-SIIs must incorporate these buffer rates into their capital planning and regulatory compliance frameworks.

Compliance officers at the affected banks should verify their capital adequacy calculations reflect the applicable buffer rate ahead of the 1 January 2027 effective date.
