Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. 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. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. 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. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption.
