1 000 000 000 Dinara

The Republic of Serbian Krajina was a self-declared Serb entity within Croatian territory, unrecognized internationally and entirely dependent on Belgrade for practical support — including its currency. This note was printed at ZIN in Belgrade, and the institutional fiction of a separate "Narodna Banka Republike Srpske Krajine" barely concealed what was effectively a monetary extension of the National Bank of Yugoslavia. By late 1993, Serbian federal inflation was already catastrophic, and the RSK's own denomination spiral tracked it closely. One billion dinara as a face value reflects not just wartime disruption but the near-total collapse of purchasing power across the broader Yugoslav successor currencies during this period.
