NLB has been placed on the list because its total assets account for over 20% of GDP, while NLB and Unicredit are among the top three lenders in the country.

The first version of the list included the state-owned development bank SID, but it has been replaced by Unicredit.

Aside from the trio, Banka Koper and SKB will be indirectly supervised through their parent banks, respectively Intesa SanPaolo and Societe Generale.

The list includes 120 key eurozone banks that together account for almost 85% of total banking assets.

They are already subject to asset quality reviews, which will be followed by stress tests.
