Block Trades

Effective on trade date Monday, September 10, 2018, and pending all relevant CFTC regulatory review periods, this Market Regulation Advisory Notice will supersede CME Group Market Regulation Advisory Notice RA1810-5 from August 13, 2018.  It is being issued to adopt a single convention for meeting the block trade minimum threshold in all inter-commodity CME and CBOT short term interest rate futures spreads and futures combinations, which will require the sum of the legs of the spread or combination to meet the larger of the threshold requirements for the underlying products. The change will eliminate the current exception applicable to Three Month Eurodollar-30-Day Federal Funds spreads.
