Bulgarian National Bank

The Bulgarian National Bank (Bulgarian: Българска народна банка, romanized: Bulgarska narodna banka, IPA: [ˈbɤɫɡɐrskɐ nɐˈrɔdnɐ ˈbaŋkɐ], BNB) is the central bank for Bulgaria within the Eurosystem. Before the country adopted the euro on 1 January 2026, it was responsible for issuing the former national currency, the lev.

Headquartered in Sofia, the bank was established in 1879. It is the 13th-oldest continuously existing central bank in the world. The bank has a key role in the Bulgarian economy. An independent institution responsible for issuing all banknotes and coins in the country, BNB is tasked with safekeeping the government's currency reserves. It is also the sole owner of the Bulgarian Mint.
