The Most Tangible Form of European Economic and Financial Integration: The Euro

English (OpenAlex)

The European Union (EU) passed through different stages of integration, expanding from an initial sectorial economic community to an integrated and unified bloc in many areas. While the enlargement of the EU strengthened the horizontal integration, Economic and Monetary Union (EMU) policies deepened the vertical integration of the Union. As the Euro celebrates its 26th year in 2025, this study assesses the Euro’s overall impact on the EU integration policy. The methodology of the study consists of examining the theoretical background of economic integration models and presents the relevant financial policies in the academic literature. The study evaluates then the stages of the single currency with the horizontal and vertical integration and examines the impact of the Euro using the 2002-2024 intra-EU export growth rates and major economic indicators in both Euro-zone and non-Euro-zone countries. The economic and statistical figures provide a comparative data within the EU-27. While our findings indicate that the use of the Euro is not an “automatic” advantage or disadvantage, it provides nevertheless both financial and political benefits and stability, especially within the EU’s convergence criteria and the European integration process.
