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. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Over 30% of the assets of credit unions are investments in government securities, certificates of deposit of banks and savings loan associations, as well as in the parent credit unions, and other risk-free investments. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. The supreme body of the World Council of Credit Unions is the Assembly, which elects the president and the board of directors of WOCCU. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. The right to use the services of the credit union have only its members.
