Bulgaria plans to adopt the euro and become the 21st member state of the eurozone. The Bulgarian lev has been on a currency board since 1997, with a fixed exchange rate initially against the Deutsche Mark and subsequently its replacement the euro. Bulgaria's target date for introduction of the euro was 1 January 2025. However, the 2024 ECB convergence report concluded that Bulgaria did not meet the convergence criteria due to high inflation, so this timeline has been delayed. The Bulgarian National Bank and several Bulgarian politicians have expressed their desire to join as soon as possible, and project that inflation will be low enough by the end of 2024. If Bulgaria adopts the euro, it will become the second national currency of the country after the lev, which was introduced over 140 years ago. The fixed exchange rate is 1.95583 lev for 1 euro.
