The statutory mandate of the Magyar Nemzeti Bank (MNB) is to achieve and maintain price stability, preserve financial stability and support the Government's policies on economic and environmental sustainability.

Monetary policy instruments are the instruments used by the central bank in the practical implementation of monetary policy. In designing and operating the instruments, the MNB aims to ensure that the instruments used support the implementation of monetary policy, and in particular the implementation of the central bank's interest rate policy. 

The range of possible instruments of the central bank is set out in Act CXXXIX of 2013 on the Magyar Nemzeti Bank. The potential range of instruments includes all central bank instruments that the MNB may use under the applicable central bank law. The business instrument pool is the set of instruments for which the MNB has a set of business conditions or a valid central bank regulation in force. Applied instruments comprise the part of the business instrument pool for which transactions between the MNB and its counterparties are continuous or regular.
