Equity Options on Futures: E-mini S&P 500 options blocks are here

E-mini S&P 500 (ES) options blocks bring greater flexibility and capital efficiency to trading strategies

S&P 500 options trades are often negotiated in a delta-neutral manner, frequently involving a synthetic combo. Trading OTC has allowed participants to make capital commitments in a private, bilateral negotiation. Now delta-neutral E-mini S&P 500 options blocks may provide a more capital-efficient listed alternative to OTC combos.

Understanding delta-neutral ES options blocks

  • Block E-mini S&P 500 futures as part of a delta-neutral E-mini S&P 500 options on futures trade.
  • 100% of the trade can be privately negotiated and consummated, and subsequently reported to CME Group.1
  • Each S&P 500 option leg in a block trade must satisfy the 250-contract minimum.2
  • Reporting time window now extended from 5 to 15 minutes during non-US hours for all block-eligible equity index futures and options products.3

Introduction to Equity Options Blocks Enhancements

Key benefits

Increase capital efficiency

Save with margin offsets on listed, delta-neutral covered futures and options block trades for relief from common OTC charges related to Basel, RWA, and SLR.

Manage exposure with no break-up risk

Mitigate counterparty credit exposure and get a 100% match guarantee with a delta-neutral covered options block at CME Group. The trade is bilateral with no need to expose the trade.

Reduce paperwork 

No ISDA or CSA documentation is required to execute a covered futures and options block trade at CME Group, making more seamless execution possible.

Get a delta-neutral proxy for OTC combos

Trading delta-neutral is the preferred convention for larger S&P 500 options trades requiring capital commitment. Covered options block trades can replace the need for an OTC synthetic combo.
