100 Leva

Bulgaria's 100 Leva was first issued in this format following the 1999 currency reform, when the lev was redenominated at a ratio of 1,000 old leva to one new lev — a consequence of the catastrophic hyperinflation and banking collapse of 1996–97 that wiped out household savings and briefly pushed annual inflation past 1,000 percent. The currency board arrangement introduced alongside the reform pegged the lev to the Deutsche Mark, later transferred to the euro at the fixed rate of 1.95583.

Printed in-house by the BNB's own facility in Sofia, a capability the bank has operated since 2001. Designer Kiril Gogov worked across several denominations in the post-reform series.
