100 Leva

The P-130 belongs to Bulgaria's fourth series of leva banknotes, introduced following the country's currency board arrangement that pegged the lev hard to the euro after the catastrophic hyperinflation of 1996–97. That crisis — which saw annual inflation exceed 1,000 percent and wiped out household savings — is the direct reason Bulgaria maintains one of the most conservative monetary frameworks in Europe, and why the National Bank has consistently commissioned high-security print runs from established European contractors rather than developing domestic printing capacity.

Oberthur Fiduciaire's involvement in this series reflects a long-standing relationship with smaller central banks across the EU periphery. The hologram and OVI elements on this denomination are among the more elaborate applied to any Bulgarian note to date.
