Bulgaria to Join Eurozone as 21st Member from January 1, 2026

On July 8, 2025, the European Union (EU) finance ministers gave their final approval for Bulgaria to adopt the euro as its official currency starting January 1, 2026. This move will make Bulgaria the 21st member of the eurozone.

From Lev to Euro

Bulgaria will officially replace its national currency, the lev, with the euro. The fixed conversion rate is set at 1.95583 lev per euro. Prime Minister Rossen Jeliazkov hailed the decision as a “landmark moment” and reaffirmed the government’s commitment to a smooth and effective transition.

Reactions and Support

Top EU figures congratulated Bulgaria:

• European Commission President Ursula von der Leyen said the euro would bring “big benefits for Bulgarian people and businesses”.

• European Central Bank (ECB) President Christine Lagarde welcomed Bulgaria into the single currency area.

• EU Economy Commissioner Valdis Dombrovskis stated that the change represents a brighter, more prosperous future at the heart of Europe.

Economic and Political Context

Bulgaria’s journey to the eurozone was delayed mainly due to high inflation, which prevented earlier accession. The European Commission and ECB recently confirmed that Bulgaria now meets the required economic criteria.

However, the shift comes amid political instability. Bulgaria has seen seven national elections in three years, with the last held in October 2024. Public opinion remains divided. Concerns over inflation and loss of purchasing power have led to protests in the capital, Sofia, with demonstrators demanding to retain the lev.

Strategic Importance

Proponents argue that joining the eurozone:

• Will boost economic stability

• Strengthen ties with Western Europe

• Provide protection against external influences, including Russian interference

Critics, including some opposition leaders, previously suggested holding a referendum, but this was dismissed by the Bulgarian parliament.

Enlargement of the Eurozone

When the euro was first introduced in 2002, only 12 countries adopted it. Since then, more have joined:

• Slovenia (2007)

• Cyprus and Malta (2008)

• Slovakia (2009)

• Estonia (2011)

• Latvia (2014)

• Lithuania (2015)

• Croatia (2023)

With Bulgaria’s inclusion in 2026, the eurozone will have 21 member countries.

Criteria for Euro Adoption

To join the eurozone, EU countries must meet the Maastricht criteria, which include:

• Low and stable inflation

• Sound public finances

• Stable exchange rates

• Long-term interest rate control

Inflation must be no more than 1.5 percentage points higher than that of the three best-performing EU countries.
