Hungarian National Bank. The Hungarian National Bank is the central bank of Hungary and as such part of the European System of Central Banks (ESCB). It was established in 1924 as a successor entity of the Austro-Hungarian Bank, under the economic assistance provided to Hungary by the Economic and Financial Organization of the League of Nations. The bank calls itself the Magyar Nemzeti Bank in its English communications and occasionally clarifies that name with the expression the central bank of Hungary. The bank doesn't call itself the Hungarian National Bank in English.
