The National Bank of Yugoslavia (NBY, Serbo-Croatian: Narodna banka Jugoslavije) was the central bank of Yugoslavia, succeeding the National Bank of the Kingdom of Serbia in Belgrade in 1920. It was formally known as the National Bank of the Kingdom of Serbs, Croats and Slovenes until 3 October 1929, and as the National Bank of the Kingdom of Yugoslavia from then until the invasion of Yugoslavia in April 1941.
Between 1941 and 1944 during the occupation of Yugoslavia, its former operations were taken over by the Croatian State Bank in the Independent State of Croatia and the German-controlled Serbian National Bank in occupied Serbia, while the rest of the Yugoslav territory was forcibly annexed to the Bulgarian, German, Hungarian and Italian currency zones.
The Yugoslav central bank was re-established in 1945 by the Communist authorities and renamed the National Bank of the Federal People’s Republic of Yugoslavia on 15 January 1946, shortened to National Bank of Yugoslavia in March 1961. It lasted under that name until 4 February 2003, when it was renamed the National Bank of Serbia with a reduced geographical scope following the breakup of Yugoslavia.
