(3)The European Banking Authority (EBA) has carried out an assessment based on the best available knowledge supplied by Member States' competent authorities on central bank eligibility in a given currency. In the case of Bulgaria, the assessment indicated that the central bank does not extend liquidity to institutions except in extreme circumstances. Upon the emergence of a liquidity risk that may affect the stability of the banking system, the Bulgarian National Bank may extend to a solvent bank lev denominated credits with maturity no longer than three months, provided they are fully collateralised by gold, foreign currency or other such highly liquid assets. Consequently, the Bulgarian lev should be considered as a currency with an extremely narrow definition of central bank eligibility.
