The introduction of the euro as the official currency of the Republic of Croatia represents a significant change with potentially far-reaching consequences for the economy, especially in the context of international trade. The euro is the official currency of the European Union and is used by most of its member states, creating a unified economic area that facilitates trade transactions among member countries. One of the key aspects of introducing the euro is the elimination of exchange rate risk. Prior to the introduction of the euro, Croatian companies that engaged in international trade had to consider fluctuations in the exchange rate of the kuna against the euro or other currencies. These fluctuations could significantly impact the profitability of trade deals. With the introduction of the euro, this risk disappears, increasing the security and predictability of business operations. This facilitates the planning and implementation of long-term trade strategies. Additionally, the introduction of the euro reduces transaction costs. When all parties involved in a trade transaction are in the eurozone, there is no need for currency conversion, which reduces bank fees and administrative costs. Moreover, the prices of goods and services become more transparent and easier to compare, which can increase competition and lower prices for consumers. The introduction of the euro may also boost international investors' confidence. The stability and strength of the euro as a global currency make Croatia a more attractive market for foreign investments. This can lead to an increase in capital investments in the Croatian economy, the creation of new jobs, and the stimulation of economic growth.
