society Maturity 11-13 Next article →

The euro is a major global currency used across much of Europe. It serves as the official money for 21 member states of the European Union. This specific group of countries is known as the eurozone.

Beyond these members, the euro is used by four European microstates and several other territories. It is also used by some European states that are not members of the EU. Currently, 358 million people live within the eurozone. Over 200 million people worldwide use currencies that are pegged to the euro.

This makes the euro the second-most traded currency and the second-largest reserve currency in the world, following the United States dollar.

The euro is managed through a complex administrative system. The European Central Bank, or ECB, is located in Frankfurt, Germany.

The ECB is an independent central bank. It has the sole authority to set monetary policy. The ECB works alongside the Eurosystem to manage the currency. The Eurosystem consists of the central banks from all eurozone countries. Together, they handle the printing, minting, and distribution of banknotes and coins. They also operate the payment systems used throughout the eurozone.

Most countries joined the euro through the 1992 Maastricht Treaty. This treaty required members to meet specific monetary and budgetary convergence criteria. Some countries have different rules. Denmark negotiated an opt-out to keep its own currency, the krone. However, the krone is pegged to the euro through the ERM II exchange rate mechanism. Sweden also turned down the euro in a 2003 referendum. Other nations have joined the EU since 1993 and pledged to adopt the euro eventually. These countries must still meet certain requirements before they can switch.

All coins feature a common side designed by Luc Luycx. This side shows the value and a map of Europe using Arabic numerals. The map on these coins has changed over time. Older designs showed only the 15 EU member states from 2002. Newer designs show a broader map of Europe. The 1, 2, and 5-cent coins still use the older map design. The other side of each coin is the national side. Each country chooses its own unique image for this side.

Some coins even feature religious leaders like Pope Francis.

Banknotes are also highly standardized but feature artistic themes. The first series of banknotes was designed by Robert Kalina.

Each note is dedicated to a specific period of European architecture. The front of the notes shows windows or gateways. The back of the notes features bridges. These designs symbolize the links between different states and the future. Each denomination has a distinct color to help users identify them. For example, the €5 note is grey and the €10 note is red.

The €20 note is blue, the €50 is orange, the €100 is green, and the €200 is yellow-brown.

There are different series of banknotes in use. The second series is known as the Europa series. This series includes six denominations. The €500 note was discontinued from issuance in April 2019. However, both the first and second series remain legal tender.

The ECB is currently planning to redesign banknotes again. They announced these plans in December 2021. A theme advisory group will submit proposals for the new designs. These proposals will eventually be voted on by the public.

The euro plays a massive role in the global economy. There is more than €1.3 trillion in circulation today. This is one of the highest combined values of banknotes and coins in the world. The currency's value often fluctuates against the US dollar. For example, the two currencies briefly hit parity in July 2022. This happened partly due to the Russian invasion of Ukraine. In the ten years ending September 30, 2025, the exchange rate averaged about $1.00 to €0.92.
