The recent disappearance of a five-year maturity gap from the set of bonds deliverable to the Chicago Board of Trade Treasury bond futures has resulted in a distinctive configuration, whereby a single T-bond will have the shortest remaining maturity in the delivery basket of bonds for a five-year period. This situation would be inconsequential were three other conditions not simultaneously present, ensuring that this single bond will probably be the cheapest-to-deliver bond over the next five years.
The report’s authors, Ramzi Ben-Abdallah and Michèle Breton, show that a similar alignment of conditions happened in 1994–1999, during the “long dry spell of the 11¼%.” They recall the detrimental repercussions of that dry spell on the bond markets and suggest possible steps to remedy the current situation.
