Will Czechia adopt the euro? The date nobody has set

Czechia is one of the richest countries in the EU's eastern half, with low debt and an export economy tightly linked to the eurozone. By most economic measures it is a natural candidate for the euro. Yet it is among the most reluctant, and the date for entry has been left blank for twenty years. The reason is political more than economic.

This explainer sets out the conditions, the positions and the practical questions, without taking a side. The criteria are covered in more detail in euro adoption criteria explained, and the current state of play in the eurozone and Czechia.

The legal position

When Czechia joined the EU on 1 May 2004, it did so with the status of a "member state with a derogation". The accession treaty obliges it to adopt the euro when it fulfils the conditions. It differs from Denmark, which has a formal opt-out, and from the United Kingdom, which had one before leaving the EU. A Czech attempt at an opt-out of a different kind, from the Charter of Fundamental Rights, is told in the Charter opt-out explained. Czechia therefore cannot simply decide never to join, though in practice it controls the timing because the conditions include steps that only it can take. A referendum on joining the euro is not required by law, although some politicians have proposed one.

Slovakia adopted the euro in 2009, Croatia in 2023 and Bulgaria in 2026 (as of 2026; check the ECB). Poland, Hungary, Romania and Sweden are also outside the euro area, as is Czechia.

The convergence criteria

The conditions are set out in the Maastricht Treaty. They cover five areas, summarised here in general terms.

• Price stability: inflation not far above that of the best-performing member states over the previous year.
• Public finances: a government deficit under 3 per cent of GDP and debt below 60 per cent of GDP or falling towards it.
• Exchange rate: participation in the exchange-rate mechanism ERM II for at least two years without severe tension and without devaluing the currency's central rate.
• Long-term interest rates: not far above those of the best-performing states.
• Legal convergence: national laws, including the statute of the central bank, compatible with the treaties and the independence of the central bank.

The European Commission and the European Central Bank assess progress in regular convergence reports. Czechia has met some of the criteria in some years and not others. The decisive step in practice is entering ERM II, which requires the government and the Czech National Bank to agree with the eurozone countries and the ECB on a central rate for the koruna. No Czech government has applied to do so.

The politics

Opinion in Czechia has been divided for years, and the divide runs along party lines more than along economic ones.

The Civic Democratic Party (ODS), founded by the former president Václav Klaus, has been the main voice against, arguing that the koruna and an independent monetary policy are an advantage. The ANO movement of Andrej Babiš has also opposed the euro in recent years. The far-right Freedom and Direct Democracy party (SPD) and the Communists are against. The Social Democrats once favoured entry, and parties such as the Christian Democrats and TOP 09 have been more open to it in principle, with differences about timing. President Zeman, who held office from 2013 to 2023, argued for early entry, while his predecessor Klaus was a prominent critic. The current president, Petr Pavel, has spoken in favour of preparing for the euro (as of 2026; check his statements).

In 2012 the centre-right government of Petr Nečas decided that the country would not set a date for entry, and subsequent governments have mostly followed that line. The coalition programme of the Fiala government (2021 to 2025) did not commit to a date, and the Babiš government that took office in December 2025 is against joining the euro in the near term. The practical result is that Czechia will not enter ERM II any time soon, and so cannot adopt the euro for at least two years after that point.

Published surveys by Eurobarometer and by Czech pollsters have for years shown that a majority of Czechs oppose adopting the euro, often a larger majority than in other countries outside the eurozone. Reasons given in such surveys include fear of higher prices, loss of national control and doubts about eurozone institutions. The exact figures change by year and by question wording, so check the pollster.

What would change

If Czechia joined, several things would change. The Czech National Bank would no longer set interest rates; the ECB would, for the whole eurozone. The CNB would remain a member of the Eurosystem and a supervisor, as described in how the Czech National Bank works. Exchange-rate risk against the euro would disappear, and with it the cost of converting currency for firms that trade with the eurozone. That matters for a country that sells most of its exports to euro-area states, not least its car makers (Hyundai in Nošovice and the Czech car industry). Prices in shops would be quoted in euros, with a legal period of dual display, as other countries have experienced.

Loans and mortgages are an area where households would notice the shift most. Today, most Czech mortgages are in koruna, with rates linked to Czech market rates. After adoption, new loans would follow eurozone rates, and older loans would be converted. If you want to see how repayments respond to rate changes, you can model repayments with the mortgage calculator on Hypoteky.com.

The koruna's own story, including the reasons it has floated since 1997, is told in what the Czech koruna is and why Czechia kept it and how the koruna exchange-rate regime works. The inflation target is explained in Czech inflation targeting explained.

The arguments

Supporters of adoption stress lower transaction costs, greater price transparency, protection against currency swings, and a stronger voice in euro-area decisions. They note that eurozone members have the ECB as a lender of last resort in a crisis, which the Czech National Bank cannot replicate.

Opponents stress the value of a separate monetary policy that can respond to Czech conditions, a floating exchange rate that has cushioned shocks, and doubts about the euro area's governance and rescue mechanisms. They also point to the experience of countries where prices rose after the changeover, although economists disagree on how large the effect was.

Economists often add that the debate depends on conditions at the moment of entry, because a country joining at a poor exchange rate or with an overheating economy can face problems, which is the reason for the two-year test in ERM II.

Frequently asked questions

Does Czechia have to join the euro?

In principle yes: it has no opt-out in its accession treaty. But there is no deadline, and the process starts only when a government enters ERM II.

What is ERM II?

An exchange-rate mechanism in which a candidate currency is kept within a band against the euro for at least two years.

Which countries use the euro in Central Europe?

Slovakia since 2009, Croatia since 2023 and Bulgaria since 2026. Czechia, Poland and Hungary have kept their own currencies.

Where do Czech parties stand?

Mostly against near-term entry, though some parties support it in principle. Check party programmes for current positions.
