CME, CBOT, NYMEX, and COMEX are independent Exchanges, each of which remains a separate, CFTC registered Designated Contract Market with self-regulatory responsibilities and maintains its own set of rules. To provide a common regulatory framework for market users, the rulebooks have been substantially harmonized, making the rules parallel in structure, numbering, and language where possible. Please note that the rules in the NYMEX Rulebook are applicable to both NYMEX and COMEX.
CME Group has received temporary registration as a swap execution facility (SEF) in addition to our current exchanges and trading platforms. Our SEF is governed by the SEF Rulebook.
