CME Group Announces Solution to Delivery Gap in US Treasury Bond Futures CME Group, the world's leading and most diverse derivatives marketplace, today announced a solution to address a gap in the delivery basket of the U.S. Treasury Bond futures. The gap results from the U.S. Treasury's suspension of 30-year Treasury bond issuance between early 2001 and early 2006. CME Group will exclude the 5-3/8% February 2031 U.S. Treasury bond (cusip 912810FP8) from contract grade eligibility for the June 2015, September 2015, and December 2015 delivery months only. jlne.ws/18LxnZI
