Euro (EUR)

By Laurent · Aug 2026

The official currency of 20 European Union member states forming the eurozone. The euro is the world's second most traded currency and the second largest reserve currency after the U.S. dollar.

The Euro in Forex

The euro (ISO 4217 code: EUR) was introduced in 1999 for electronic transactions and as physical notes and coins in 2002. It replaced legacy currencies including the Deutsche Mark, French Franc, and Italian Lira. EUR/USD is the most traded currency pair globally, accounting for approximately 23% of all forex turnover.

Eurozone Economics

The European Central Bank (ECB) sets monetary policy for the entire eurozone. ECB interest rate decisions, press conferences, and forward guidance are major drivers of EUR movements. The eurozone's largest economy, Germany, heavily influences euro sentiment, making German data releases like the IFO Business Climate and ZEW Economic Sentiment particularly important.

The euro accounts for about 20% of global foreign exchange reserves. Its appeal as a reserve currency is limited by the absence of a unified eurozone government bond (each country issues its own debt), which fragments the euro-denominated bond market.

Key fact: The euro is used by over 340 million people in 20 countries. The EUR/USD pair is often called "Fiber" by forex traders, a nickname that emerged in the electronic trading era.

Key EUR Drivers

Beyond ECB policy, the euro responds to eurozone Gross Domestic Product (GDP), inflation data, political stability (elections, EU cohesion), and the Interest Rate Differential between the ECB and other major central banks.
