Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. The economic basis of credit unions - finances of a household. The main objective of the credit union - to ensure financial stability of a household, to ensure the priority of their shareholders' financial interests. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
