The Croatian National Bank is the central bank of the country that has been implementing a certain exchange rate regime in Croatia since independence, which will change with the entry into the Eurozone. During the existence of the Croatian exchange rate regime in the last 20 years, measures within the monetary policy framework were implemented, mostly in the form of foreign exchange auctions, high reserve requirements and minimum required foreign currency claims. The aim and purpose of implementing these measures has always been to maintain price stability through constant low and stable inflation. It was possible for the central bank to implement these measures because of the use of a managed floating exchange rate regime that corresponds to the characteristics of the Croatian economy and development. But, during these years, Croatia also was making progress towards joining the European Union and the Eurozone, which brings changes to the current regime. This path towards the EU has brought great progress for the country because, for membership and accession, it had to improve in every aspect. The EU has helped Croatia overcome crises and opened its market more to other European countries. The next step in progress is the introduction of the euro, which is expected in the period until the next government's term, because of the current performance indicators in fulfilling its obligations and tasks. The introduction of the euro will bring a number of advantages and disadvantages, but it is important to emphasize that the benefits of the introduction of the euro are significant and lasting, while the losses are mostly small and one time things. The main advantage of the introduction of the euro for the Republic of Croatia is the elimination of currency risk, and the main disadvantage is that Croatia is losing the opportunity to implement its monetary policies and regimes. Although central bank will no longer use their monetary policy but the policy of the European Central Bank, the two are quite close, so the change should not be a big shock for Croatia and its citizens. After the introduction of the euro, Croatia will continue with fiscal and structural policies because if it wants to remain competitive in today's fast-growing market, it must grow and prosper from year to year.
