Is the CME a regulator?
ANS: Founded in 1974, the U.S. Commodity Futures Trading Commission (CFTC) is the primary regulator of the U.S. futures and options on futures markets. CME, CBOT, NYMEX and COMEX are separate CFTC-registered and regulated Designated Contract Markets (DCMs) with self-regulatory responsibilities.
