The National Bank of Romania has incorporated European Banking Authority guidelines on identifying entities as ancillary services undertakings into its supervision of credit institutions. The guidelines establish criteria based on the definition in the EU Capital Requirements Regulation. The framework applies to the National Bank of Romania and the credit institutions for which it is the competent authority at individual, consolidated or sub-consolidated level. It also applies to the central bank in its capacity as a competent authority under the Markets in Crypto-Assets Regulation.
