Bosnia's 1993 hyperinflation was among the most severe in modern European history, unfolding simultaneously with active military siege. The Narodna Banka Bosne i Hercegovine lacked the infrastructure and security to issue clean new currency fast enough, so existing notes were overprinted — handstamped by municipal authorities in Travnik and Sarajevo — to authorize their local use. The practice was improvised necessity, not policy design.

Travnik-stamped examples are considerably scarcer than Sarajevo issues, reflecting the relative isolation and smaller administrative capacity of that city during the conflict period.
