In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. In recent decades, many credit unions began to resort to such form of service as 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. 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.
