Eastern Europe waits on the euro

Eastern Europe’s largest non-euro economies are still holding on to their national currencies despite their long-term legal obligation to join the single currency, as Poland, Czechia, Hungary and Romania weigh monetary sovereignty against lower currency risk and deeper integration.

The euro loses some political appeal in eastern EU markets

Warsaw, Prague, Budapest and Bucharest remain the largest economies in the eastern part of the European Union that have not adopted the euro. Formally, most EU countries outside the single currency are expected to join once they meet the required conditions. Denmark is the exception because it has a treaty opt-out. In practice, the region’s biggest economies are in no hurry to give up the zloty, koruna, forint and leu.

Bloomberg’s May 29, 2026 newsletter framed the issue as Eastern Europe’s biggest economies resisting the euro’s appeal. That resistance is not a rejection of the European Union. It is a cautious calculation about losing national interest rates, national exchange rates and part of the macroeconomic flexibility that helped these countries navigate recent shocks.

The debate has become more sensitive after years of high inflation, energy disruptions, Russia’s war against Ukraine, rising defence spending and weak growth in parts of the euro area. The euro remains a symbol of European integration, but it is no longer automatically seen as a shortcut to faster growth.

Bulgaria joined, but the big economies did not follow

Bulgaria became the 21st member of the euro area on January 1, 2026. The European Central Bank said the Council of the European Union approved accession and fixed the conversion rate at 1.95583 Bulgarian lev per €1. The step showed that euro-area enlargement is still possible, but it is happening one country at a time rather than in a regional wave.

Bulgaria’s move has not changed the stance of the region’s larger neighbours. Poland, Czechia, Hungary and Romania remain outside the euro area. They are deeply integrated into European trade, receive investment from euro-area economies and depend on the single market, but they continue to use their own currencies.

The reason is that euro adoption is no longer viewed as a purely technical change. It means transferring monetary policy to the European Central Bank. Monetary policy is the management of interest rates, banking-system liquidity and other tools that influence inflation, exchange rates and credit costs. For countries with different inflation histories and economic structures, that step remains politically difficult.

Poland protects the zloty as a growth buffer

Poland is the largest economy in the region outside the euro area and the clearest example of a country that sees no urgency in adopting the single currency. The zloty is not only a symbol of sovereignty but also an economic buffer. A buffer, in this context, is a mechanism that helps absorb external shocks through exchange-rate movements and independent central-bank decisions.

Poland’s economy has grown faster than many euro-area countries in recent years, while its domestic market has become a key source of resilience. For businesses trading with Germany, France or Italy, the euro would reduce currency-conversion costs. For the government and the central bank, however, keeping the zloty preserves the ability to set national interest rates, respond to inflation and support export competitiveness.

The political argument is also strong. In Poland, the euro is regularly part of a broader debate about sovereignty, prices and relations with Brussels. Even pro-European forces have been reluctant to turn euro adoption into a near-term goal because public concerns about post-changeover price increases remain visible.

Czechia relies on the koruna and caution

Czechia is one of the EU’s most industrially integrated economies, but euro adoption remains delayed. The Czech government previously acknowledged a joint recommendation by the Finance Ministry and the Czech National Bank not to set a date for adopting the single European currency. That effectively preserved a wait-and-see policy.

The Czech argument is less emotional than Poland’s and more technocratic. Prague recognizes the benefits of the euro for exporters, especially companies tied to German industry. But policymakers and the central bank continue to point to the value of the koruna and independent rate-setting.

For Czechia, the koruna is a tool for economic adjustment. Once a country joins the euro area, interest rates are set for the entire currency union, where conditions in Germany, Spain, Italy, Slovakia and Greece may differ sharply. For a small open economy, that can be useful in stable years but risky during local overheating, inflation spikes or abrupt changes in external demand.

Hungary links the euro to trust and risk

Hungary keeps the forint despite periodic debate about the euro’s potential benefits for price stability and investment. In Hungary, the single-currency question is closely tied to confidence in economic policy, relations with the European Union and the sustainability of public finances.

The Hungarian National Bank said after its May 26, 2026 meeting that risk perception depends, among other factors, on expectations around EU funds, the fiscal outlook and euro adoption. That shows the single currency is present in the country’s financial-risk assessment, but it has not become a practical transition plan.

For Hungary, the euro could reduce currency risk and lower the cost of external financing. But membership requires more than preference. It requires durable compliance with the criteria, confidence in fiscal policy and legal compatibility. For now, the forint remains an adjustment tool, even if its volatility can also become a source of risk.

Romania is politically closer but technically farther away

Romania differs from Poland, Czechia and Hungary because public support for the euro has generally been stronger and political resistance weaker. Its challenge is different: meeting the entry conditions remains difficult because of fiscal deficits, inflation and the need for sustained macroeconomic adjustment.

The convergence criteria, often called the Maastricht criteria, include price stability, sound public finances, acceptable long-term interest rates, participation in the exchange-rate mechanism for at least two years and legal compatibility with euro-area rules. The exchange-rate mechanism is a system in which a candidate country’s currency must remain stable against the euro before accession.

Romania shows that political willingness alone does not produce a quick currency change. Even if businesses and parts of society see the euro as protection against currency risk, the country must prove that it can live without devaluation, without independent interest rates and without recurring budget pressure.

Public opinion remains mixed

Flash Eurobarometer 2025 shows that 55% of respondents in EU countries that have not yet adopted the euro personally support the idea of introducing the single currency, while 52% think it would have positive consequences for their country. But averages hide wide differences between member states.

The same survey found that majorities in Czechia and Poland expected negative consequences for their countries if the euro were introduced. That is a significant signal for politicians: voters can support European integration while remaining sceptical about a specific currency reform.

The main fear is prices. Consumers often expect businesses to round prices upward after euro adoption, although economists debate the scale of that effect. A second fear is loss of control: once a country gives up its currency, it can no longer set its own key interest rate. A third concern is joining a currency union that includes economies with weaker growth and higher debt burdens.

The euro area no longer looks like an automatic growth anchor

In the 2000s, the euro was seen in much of Eastern Europe as the final step toward a Western economic model. Today the picture is more complicated. The euro area remains the EU’s largest market and financial centre, but its own performance is uneven. Germany has faced industrial weakness, France fiscal pressure, Italy high debt and the European Central Bank has had to set policy for the average of the entire bloc.

The International Monetary Fund’s April 2026 Regional Economic Outlook projected euro-area growth at 1.1% in 2026 amid elevated risks. For Poland or Romania, where growth expectations may be higher, that sharpens the question: why enter a currency regime that reduces autonomy while their economies are still catching up with Western Europe?

Not joining the euro also carries costs. National currencies create exchange-rate risk for companies and households, increase the cost of hedging and can intensify inflation pressure when currencies weaken. For foreign investors, a national currency can also mean an additional risk premium.

Business often wants the euro, politicians want time

The gap between business and politics remains one of the central factors. Exporters, banks, large manufacturers and investors often see benefits in the single currency. The euro reduces conversion costs, simplifies pricing, lowers exchange-rate risk and makes financial reporting more comparable.

For politicians, the calculation is harder. Euro adoption is irreversible. After the changeover, a country cannot devalue its currency to support exports or conduct a fully independent interest-rate policy. If prices rise faster than expected after adoption, the political cost falls on the national government, even if the causes are broader.

That is why the region’s largest economies are choosing delay. They are not leaving the European project, rejecting the euro legally or breaking economic integration. They are simply avoiding a timetable that would force them to act in the near term.

Non-adoption has become a new waiting norm

Eastern Europe has entered a period of currency pragmatism. Bulgaria has joined the euro area, Croatia did so earlier, and the Baltic states and Slovakia have used the euro for years. But Poland, Czechia, Hungary and Romania show that economic size changes the calculation. The larger the domestic market and the stronger the national monetary system, the more valuable the national currency becomes as a policy instrument.

For the European Union, this creates institutional ambiguity. Formally, euro-area enlargement remains a treaty objective. In practice, some countries may remain in a waiting mode for decades, not meeting all criteria, not entering the exchange-rate mechanism and not setting accession dates.

That status is useful as long as the national currency is stable, inflation is under control and investors trust economic policy. If those conditions weaken, the case for the euro strengthens. For now, the region’s largest eastern economies believe flexibility is more valuable than the symbolic completion of integration.

According to experts at International Investment, resistance to the euro in Poland, Czechia, Hungary and Romania should not be read as a turn against Europe. It is a sign that the single currency is no longer viewed as an unconditional reward for successful integration. For catch-up economies, the national currency remains insurance, but that insurance works only with disciplined fiscal policy, an independent central bank and investor confidence. If those elements weaken, delayed euro adoption can quickly turn from an advantage into a vulnerability.
