The Federal Credit Union Act is an Act of Congress enacted in 1934. The purpose of the law was to make credit available and promote thrift through a national system of nonprofit, cooperative credit unions. This Act established the federal credit union system and created the Bureau of Federal Credit Unions, the predecessor to the National Credit Union Administration, to charter and oversee federal credit unions. The general provisions in the Federal Act were based on the Massachusetts Credit Union Act of 1909, and became the basis of many other state credit union laws. Under the provisions of the Federal Credit Union Act, a credit union may be chartered under either federal or state law, a system known as dual chartering, which is still in existence today.
