The process of Croatia's accession to the European Union has taken the first and at the same time a basic step towards the euro area. In the meantime, the Republic of Croatia has committed itself to the introduction of the euro as its own national currency. When introducing the euro, the basic problem arises, and that is the criterion of convergence. In the last few years, it is possible to see the conditions for an increase in gross domestic product, a reduction in public debt, but it is still necessary to take the last steps towards the introduction of the euro. Only the introduction of the euro will clearly affect the economic trends of these areas. In particular, the introduction of the euro would eliminate currency risks within the economy itself, but would also reduce borrowing costs. In that way, the risks associated with the outbreak of the currency crisis, in the banking crisis, would be reduced. The introduction of the euro would encourage international trade and investment, which would contribute to the development of economic growth. Specifically, according to the Governor of the Croatian National Bank, based on previous experiences with other EU member states that have already converted national currencies, the effect of the conversion of the Kuna into the euro on increasing overall consumer price inflation in Croatia is to be expected. What is expected is an amount of 0.20 percentage points in relation to the increase in the consumer price index in the period of half a year before and after the conversion.
