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. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the 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 cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution.
