In recent decades, many credit unions began to resort to such form of service as Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. 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. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). As of the January 1, 2012 the national associations and confederations unite more than 196 million members participating in the 51,013 credit unions in 100 countries. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine.
