The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. 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. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. In the UK, credit unions are a source of financing of people groups. This tool is not widely used.
