National Futures Association

The CFTC Act of 1974 also authorized the creation of a national futures association. The National Futures Association (NFA) was established in 1981.
It is a self-regulatory body of the futures industry and is supported by the futures industry. Its members have established rules -- often above and beyond state or federal laws -- to maintain fair practices and protect the integrity of the industry.
Relationship of the CFTC to the NFA
The relationship between the CFTC and the NFA is similar to the relationship between the Securities Exchange Commission (SEC) and the National Association of Securities Dealers (NASD).
