Margin Services

Explore our suite of tools designed to facilitate capital efficiencies for a capital-constrained world.

Reduce counterparty credit risk

CME Clearing acts as the counterparty to every trade, mitigating bilateral counterparty credit risk. As cleared positions do not require bilateral credit, you can free up credit lines.

Improve capital ratios, lower charges

Where it makes sense to use cleared instruments in place of uncleared exposures, you can improve capital ratios and lower regulatory fees associated with bilateral positions.

Increase operational efficiency

Add the efficiency of working with one leading clearinghouse for futures, options, cleared OTC transactions, and cash, across multiple asset classes for your clearing needs.

Get simple, easy-to-use tools for integrating with or connecting to powerful margin engines. The CME Clearing Online Risk Engine (CORE) Margin API is licensed to more than 80 entities. 

CME Margin Services has saved market participants as much as $2.34 billion in overnight funding costs, and provided indicative margin savings up to 89%.
