Bulgaria will become the 21st European country to adopt the euro from Jan. 1, marking a historic milestone for the country, European institutions said in statements welcoming the newest member of the single currency bloc.

The European Central Bank described the move as a significant opportunity for citizens and businesses across the euro zone, noting that the transition is expected to bring greater economic stability, smoother transactions and deeper European integration. For Bulgaria, adopting the euro will help build a stronger foundation for long-term growth and economic resilience, the ECB said.

The ECB and Bulgarian authorities are working closely to ensure a smooth transition. The official conversion rate has been set at 1.95583 lev per euro.

European officials stressed that the euro represents more than just a currency. According to the ECB, it is a stable and reliable means of exchange that helps protect savings and purchasing power. Membership will also give Bulgaria a seat at the euro zone’s decision-making table.

At a time of heightened geopolitical uncertainty, the expansion of the euro zone sends a message of unity and solidarity, the ECB added. Joining the single currency is expected to create more opportunities for growth, trade and investment, while reinforcing financial stability and demonstrating that European integration remains on track.
