Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. 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. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. Important specifics of creating a credit union - an initiative order of organization: people do not receive any instructions, orders or regulations, the unification into a credit union occurs by their will and decision. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. Credit union as a consumer cooperative operates on the principles of equality of all its members.
