The EURUSD is the most widely traded currency pair across the FX world. Their respective economies are also the two largest in the world. Both the EUR and the USD are major global currency reserves. While both are influenced by central banks, the Eurozone does not have central control on fiscal policy across member states. Monetary policy divergence and geopolitics also provide volatility across the pairing. The EURUSD pair accounts for roughly 30% of total daily transaction volume in the FX market.
