Designated contract market within CME Group for futures and options on major financial and commodity benchmarks.
The Chicago Mercantile Exchange (CME) is one of CME Group’s designated contract markets. In current usage, CME is both a specific exchange rulebook and part of the broader CME Group marketplace, which also includes CBOT, NYMEX, and COMEX.
CME matters in finance because the exchange rulebook determines which products trade there, how orders and block trades are handled, how margins and daily settlements work, and which delivery or cash-settlement procedures apply.
| Area | Why it matters |
|---|---|
| Product listing | Determines which futures and options are subject to CME rules. |
| Contract specifications | Defines size, tick value, delivery or settlement terms, and expiration. |
| Trading rules | Controls order handling, block trades, position limits, and market conduct. |
| Margin and clearing interface | Affects collateral, variation margin, and risk management. |
| Market regulation | Provides surveillance, rule enforcement, and disciplinary processes. |
CME Group’s official CME page describes CME as a designated contract market offering products subject to CME rules and regulations. CME Group’s designated contract markets page is the best starting point for checking whether a product is listed under CME, CBOT, NYMEX, or COMEX rules.
Do not use “CME” and “CME Group” interchangeably in contract analysis. CME Group is the corporate marketplace operator; CME is one designated contract market within that group. A futures contract listed on NYMEX or COMEX may trade through CME Group infrastructure but still be subject to that exchange’s rulebook.
