The theme of this final paper is the Croatian National Bank and the introduction of the euro in the Republic of Croatia as a new currency. The topic will begin with a breaf introduction to the concept of the Croatian National Bank; what is the National Bank, its mission and its main role in the process of introducing a new currency into Croatia. In continuation about the euro as a currency and about the process and means of introduction into our country. Like all others, the introduction of the euro has its own good and bad sides, and it is therefore very important to highlight and clarify the benefits, as well as the disadvantages that may arise with these changes. Information on the topic has been collected in a variety of ways. The introduction of the euro in Croatia is an ongoing topic, so the most information can be found and found out through various daily newspapers, magazines and online portals, where this title also appears as a common theme of the day. It is a good thing that Croatia will still outweigh most of the benefits through this process and the changes it brings, and that these costs will not cause significant harm to us and harm our further economic development and progress in the future. Although the dynamics of euro introduction depends to a large extent on us, not all of the ‘strings’ are in our hands.
