In the continuous process of its creation and with the further integrated accession of new members, the European Union has always wanted to create a single economic, social, institutional and currency area. Many of these domains have already been merged, but the integration of the currency area into the EU has not yet reached its full level. The EU has introduced the euro and created an authentic blend of a single European fiscal, economic and monetary policy among its members. In order to introduce the euro as a single currency and to facilitate the path towards the use of the currency, as all EU members do, Croatia follows all EU legal regulations and guide lines in the context of implementing the steps of introducing the euro. The EU first created the European Monetary Union (EMU), with the aim of facilitating the creation of a path towards the single currency. This allows Europe to deal with the complex benefits of a universal currency, although there are obstacles where certain countries reject the euro as a currency because they do not see it as a development perspective. The introduction of the euro as a new currency has encouraged mild consumer price inflationin selected countries, but already in Croatia, which does not significantly jeopardize the purchasing power of citizens. In this context, as in the countries that previously adopted the euro, Croatia, after a slight initial inflation, is expected to stabilize the foreign exchange market and maintain the continuity and sustainability of the purchasing power of Croatian citizens.
