Equity Options on Futures: Options Blocks Enhancements

CME S&P 500 options on futures blocks offer flexibility and a capital efficient alternative to OTC synthetic combos.

Three New Enhancements: Designed to help you manage risk with more flexibility

  • Allowance of delta-neutral S&P 500 options blocks
  • Reduced minimum block threshold for S&P 500 options to 50 contracts during all trading hours
  • Extended block trade reporting time window from 5 to 15 minutes during non-U.S. hours for all block-eligible equity index futures and options products1

With the recent closure of the CME Group trading floor, the block threshold for S&P 500 options on futures has been lowered to 50 contracts during all trading hours.

Introduction to Equity Options Blocks Enhancements

Understanding Delta-Neutral CME S&P 500 Options Blocks

  • You can block S&P 500 futures (Standard and E-mini) as part of a delta-neutral Standard S&P 500 options on futures trade.
  • 100% of the trade can be privately negotiated and consummated, and subsequently reported to CME2
  • Each S&P 500 option leg in a block trade is required to satisfy a minimum of 50 contracts3

Key Benefits

No Break-Up Risk: 100% match guarantee when you execute a delta-neutral covered options block trade at CME Group. The trade is bilateral with no need to expose the trade.

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

Risk Management: Mitigate counterparty credit exposure and associated risk with S&P 500 futures and options on futures, centrally cleared at CME.

Capital Efficiency: Save with margin offsets on listed, delta-neutral covered futures and options block trades for relief from charges commonly levied on OTC transactions from Basel, RWA and SLR

Reduced Paperwork:  No ISDA or CSA documentation is required executing a covered futures and options block trade at CME Group.
