On January 1, 2026, Bulgaria officially switched to the euro and became the 21st country in the eurozone. For the Bulgarian economy, this step is largely institutional in nature: for many years, the lev was tightly pegged to the euro through the currency board, so the market did not expect a sharp change in the monetary regime. At the same time, the country will get a seat on the ECB’s governing bodies and deeper integration into the eurozone’s financial system, according to the Experts Club information and analytical center.
Maksym Urakin, founder of the Experts Club analytical center, believes that the effect of the transition will be determined by how quickly the authorities “knock down” inflation expectations among the population and businesses: “The euro itself does not make the economy richer overnight, but it reduces transaction costs and increases investor confidence. The key test in the first few months will be controlling price speculation and communicating clearly with consumers.”
The main domestic risk around which public debate in Bulgaria is centered is inflationary expectations and fears of price “rounding” in retail and services. Such fears traditionally accompany currency changes, even if the actual effect is usually limited in time and concentrated in the sector of daily household expenses.
After Bulgaria’s entry into the eurozone, six countries remain in the EU that do not use the euro: Sweden, Poland, the Czech Republic, Hungary, Denmark, and Romania.
According to Experts Club estimates, the expansion of the eurozone will be slow in the coming years, as each of these countries has its own “stop factors” — from political constraints to failure to meet convergence criteria and budget deficit problems.
In Poland, for example, the government has publicly stated that the country is “not yet ready” for the euro and considers the zloty to be an instrument of macroeconomic flexibility that has helped it weather past shocks.
In the Czech Republic, President Petr Pavel has called for more active movement towards the euro as a factor in trade and decision-making, but there is no political consensus on the timing in the Czech Republic.
In Hungary, Prime Minister Viktor Orbán, on the contrary, has stated several times that the country should not adopt the euro.
Sweden formally relies on the results of the 2003 referendum, when 55.9% of voters opposed the introduction of the euro.
Denmark, unlike the others, has a legally enshrined right not to introduce the euro (opt-out), confirmed by a referendum in 2000.
Experts Club notes that Romania is considered the next country after Bulgaria that is most likely to apply for the introduction of the euro. However, the actual timeline depends on inflation and the budget trajectory: the European Commission indicated in its convergence materials that Romania does not meet the conditions for adopting the euro, including the parameters of public finance sustainability and legal compatibility. The public guidelines in the Romanian discussion mention a target date of around 2029, but the timing may shift depending on economic indicators and fiscal adjustments.
