As independent exchanges for many years, CME and CBOT each developed its own set of rules. Now they have merged to form one company, CME Group, but remain separate self-regulatory organizations under a single Market Regulation Department.

To make it easy for you to know and follow the rules for each exchange, we have been working to harmonize the CME and CBOT rulebooks, making the rules parallel in structure, numbering and language where possible. Read more about this process in CME and CBOT Rule Harmonization.
