Which Countries Use the Euro?


The euro is the second most traded currency in the world, behind the US dollar, with around 1.3 trillion euros in circulation as of 2019.

It is also the official currency of the European Union, with 19 of the 27 EU member states using the euro. We have created a list from 2022 of the countries using the Euro here:

  • Austria
  • Belgium
  • Cyprus
  • Estonia
  • Finland
  • France
  • Germany
  • Greece
  • Ireland
  • Italy
  • Latvia
  • Lithuania
  • Luxembourg
  • Malta
  • The Netherlands
  • Portugal
  • Slovakia
  • Slovenia
  • Spain

As well as these EU member states which use the euro, Andorra, Monaco, San Marino, and Vatican City all use the euro under formal monetary agreements made with the EU, despite not being members of the EU.

While these 4 countries are allowed to use the euro as their currency, they are not part of the eurozone. As a result, the heads of these country’s central banks are not allowed to sit on the board of the European Central Bank as is the right of EU member states. Similarly, the finance ministers of these countries are not invited to be part of the Eurogroup, which has a political influence on the EU’s monetary union and on the euro itself.

Kosovo and Montenegro also use the euro without the permission of the EU and without being members of the EU.

Which EU Countries Do Not Use the Euro?

While the majority of EU member states have adopted the euro as their currency, 8 have not. These countries are:

  • Denmark
  • Sweden
  • Hungary
  • Poland
  • Czech Republic
  • Bulgaria
  • Romania
  • Croatia

Before adopting the euro, the non-EU member states of Andorra and Monaco both previously used the French Franc, and San Marino and Vatican City both previously used the Italian Lira.

When Was the Euro Introduced?

The use of a common currency in Europe was established in the Maastricht Treaty of 1992, which was the founding treaty of the European Union. The 12 nations which concluded the Maastricht Treaty had previously been members of the European Communities organisations and all 12 are still members of the European Union, except for the United Kingdom.

While it is normal for there to be an obligation to join the eurozone as part of becoming a member of the EU, both Denmark and the UK were both granted exemption from this. Denmark is still today a member of the EU without using the euro as its currency.

While the foundations for the euro were laid in the Maastricht treaty of 1992, it was not until 1995 that the eurozone currency was actually given the name euro and it was not until 1999 that it was actually introduced.

The introduction of the euro came on the first of January 1999 when Austria, Belgium, the Netherlands, Finland, France, Germany, Ireland, Italy, Luxemburg, Portugal, and Spain all began to integrate their currencies under the eurozone banner. While the euro did really start on this date, it was only introduced in a non-physical form with those countries all still using their traditional national currencies to actually complete many transactions. These currencies also continued to be legal tender, allowing for a changeover period.

Instead of the currency being physically introduced at this time, exchange rates for these currencies were set against each other at fixed rates under collective management, paving the way for the establishment of a single currency.

Eventually, in 2002, euro notes and coins were actually introduced. As the euro currency was introduced in its physical form, the old currencies it was replacing were gradually phased out and ceased to become legal tender.

How is the Euro Managed?

Of chief importance in the management of the euro are the European Central Bank (ECB), the Eurosystem, and the Eurogroup.

The ECB is one of the most important central banks in the world, with the ECB governing council deciding on monetary policy for all eurozone countries and for the EU as a whole. Other crucial roles it plays are administering foreign exchange reserves within the EU, monitoring exchange rates, setting interest rates in the EU, and deciding on monetary objectives for the EU. On top of this, the ECB has the exclusive right to issue euro banknotes and also decides which countries can issue euro coins. Kosovo and Montenegro have no right to issue euro coins and other countries usually have to seek permission first.

The Eurosystem is the monetary authority of the eurozone, consisting of the ECB and the national central banks of the 19 eurozone members. Under this system, the national central banks operate under the ECB and both contribute to and apply policies.

Politically, the eurozone is represented by the Eurogroup which consists of the finance ministers of all eurozone countries. This group exercises political control over the currency and the EU’s policies related to unifying the economies of eurozone countries. As well as communicating informally, this group also meets a day in advance of a meeting of the Economic and Financial Affairs Council.  

How Does a Country Join the Euro?

In order to join the euro, an EU member has to meet the euro convergence criteria. The aim of this is to achieve price stability and to ensure that the eurozone isn’t negatively affected by the introduction of a new member. The criteria relate to pricing stability, a nation’s public finances, exchange rate stability, and long-term interest rates.

Price Stability

The rate of inflation is not allowed to be over 1.5% above the rate of inflation of the three best-performing member states. While this is the case, if it is deemed that price developments have been strongly influenced by exceptional events, exceptions may be made.

Public Finances

A country should not have excessive national debt.

Importantly, the ratio of gross government debt relative to GDP should not normally exceed 60% at the end of the year preceding joining the eurozone. This is unless debt levels have sufficiently diminished and are approaching 60% at a satisfactory pace. As well as this, the ratio of the annual general government deficit relative to GDP, must not exceed 3% at the end of the year preceding joining the eurozone or any of the two years after joining.

Exchange Rate Stability

The country must participate in the European Exchange Rate Mechanism (ERM) II for at least two years before joining the eurozone. This is without deviating significantly from the stipulated central rate and without devaluating their currency’s bilateral central rate against the euro in the two years before joining the eurozone.

Long Term Interest Rates

The long-term interest rate (average yields for 10 year government bonds within the past year) should not be any more than 2% above the rate of the three best-performing eurozone member states.

Exchange Rates for the Euro

The euro is a free-floating currency and as such fluctuates in value in a similar fashion to the pound sterling or the US dollar.

Where the central banks of other free-floating currencies seek to influence the exchange rate of their currencies, the European Central Bank does not exert a great deal of influence. Rather than intervening in the foreign exchange market to influence exchange rates, the ECB does not do this so that it can have a greater level of control over inflation. As such, the euro fluctuates in value in a truer fashion than many other currencies.

The euro is the second most widely traded currency in the foreign exchange markets and is also the second most widely held reserve currency.  

Doing Business in Euros

The euro is widely regarded as a stable currency and a safe one in which to conduct business. Indeed, its position as the second most widely held reserve currency is a testament to this.

However, as with all currencies, there is an inherent level of risk when conducting business in euros. The central risk for a business that uses any alternative currency when conducting business is that changes to the exchange rate could cause money to be lost.

Many small and medium-sized enterprises (SMEs) from the UK and all over the world conduct business in euros without protecting themselves against losses arising from changes to the exchange rate. Where bigger businesses tend to manage the risk posed by changes to the exchange rate, SMEs often do not tackle the problem. This is in spite of the fact that it can be done very easily.

Forward and option trades of currency have been used for a long time by businesses that need to guarantee exchange rates when trading in foreign currencies.

These methods of currency exchange allow businesses to secure the exchange rate for a future date. They allow certainty about minimum exchange rates when planning a future business in foreign currencies and can also provide insurance against unfavourable changes to the rate, while still allowing the possibility of taking advantage of favourable changes to the exchange rate.
