The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. 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). Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
