Requiem for a market: an analysis of the rise and fall of a financial futures contract

Futures contracts often include a variety of delivery optionsthat allow participants flexibility in satisfying the contract.These options have the potential to broaden the appeal of thecontact. However, if these options are valuable, they may reducethe hedging effectiveness of the contract. This article analyzesthe GNMA CDR futures contract that appears to have failed becauseof flaws in the contract's design. For the first 6 years followingits introduction, the contract attracted significant and increasingvolume, but, subsequently, the volume declined to almost zero.Over the years during which the volume experienced its mostdramatic decline, the Treasury-bond futures contract provideda better hedge for current coupon GNMA securities than did theGNMA CDR futures contract. And, over this same period, the valueof the quality option embedded in the contract often exceeded5 percent of the futures price and reached a level of 19 percentat one point. We interpret the evidence to indicate that thecontract failed because the delivery options reduced the hedgingeffectiveness of the contract for current coupon mortgage securities.
