Cash machines in Bulgaria began dispensing euros on Thursday, marking the country's entry into the Eurozone as its 21st member. The move signifies a deeper integration with the European Union for the former communist nation, which transitioned to a democracy and free market economy after 1989.

The introduction of the euro replaces the lev, though the local currency will remain in use for cash payments throughout January. However, change will be given exclusively in euros. Bulgaria, with a population of nearly 6.7 million, joined the EU in 2007 as one of its poorest members.

The historic shift arrives during a period of political instability. The conservative-led government resigned earlier in the month following nationwide anti-corruption protests. This political turmoil has fueled skepticism among the population, with concerns about potential price increases accompanying the currency change.

To meet EU requirements for Eurozone entry, the Bulgarian government successfully lowered inflation to 2.7% earlier this year, securing approval from EU leaders. However, the government's resignation has left the country without a regular budget for the upcoming year, potentially hindering reforms and access to EU support funds, further contributing to public discontent.

Bulgaria's adoption of the euro represents a significant step in its post-communist trajectory, aligning its economy more closely with the rest of Europe. The Eurozone, established in 1999, aims to foster economic stability and cooperation among its member states. However, the current political climate in Bulgaria presents challenges to a smooth transition and could impact the long-term benefits of Eurozone membership.
