International payment operations as a service offered by banks belong to the category of the more profitable ones. Transactions in international payment operations are various transfers, payments and collections based on certain capital and current transactions both in foreign currency of payment and in HRK between residents and non-residents. The Single Euro Payments Area (SEPA) is a European initiative tasked with regulating international payment transactions. All Member States of the European Union (EU) must respect and abide by the SEPA rules as a single area of payment in EUR. In the Republic of Croatia, certain laws and bylaws are prescribed for international payment operations. These are: the Law on Foreign Exchange Operations, the Law on Payments and the Law on Prevention of Money Laundering and Terrorist Financing. In international foreign exchange payment transactions, certain payment instruments are applied, such as: checks, trade credit letter, bank transfers, bank guarantees, international letters of credit, collection transactions, etc. Banks operating in the Republic of Croatia also provide international payment services to their clients. Most of these banks are members of well-known European groups operating around the world. Therefore, these banks have enabled a wide range of their services and products for their clients, but also the execution of international foreign exchange payment transactions in the shortest possible time and with the lowest possible costs of executing these transactions.
