Why was the euro introduced by participating European Union countries?

The introduction of the euro was driven by the goal of fostering deeper economic integration among European nations. By establishing a single currency, supporters aimed to boost trade by eliminating foreign exchange fluctuations and reducing costs for businesses and consumers.12

The move toward a common currency was formalized through the Maastricht Treaty, which sought to build upon the success of the European Community in promoting the free exchange of goods, labor, and finance. This initiative was designed to create a stable monetary environment managed by common institutions, such as the European Central Bank, which was mandated to maintain price stability across the euro area.132

While the transition involved significant adjustments—including strict convergence criteria regarding budget deficits, public debt, and inflation—the participating countries adopted the euro to strengthen their collective economic ties and solidify the political and social cohesion of the European Union.132
