Abstract

AbstractThis research applies an entirely new approach to examining the efficiency of futures markets for Treasury bills and avoids many shortcomings of previous studies that rely on comparing yields on spot versus futures market positions. Efficiency is examined by comparing the consistency of yields within the futures market itself since, at one time, the International Monetary Market (IMM) traded futures contracts for both three‐month and one‐year bills. The results indicate a remarkably large average annual yield differential of 32 basis points when the yields on the one‐year contract are compared to the appropriate corresponding strip of three‐month contracts. Possible explanations such as low volume, market thinness, transaction costs, strategy interdependence, serial correlation among differences, and daily resettlement (the Cox, Ingersoll, and Ross effect) are unsuccessful in explaining this pricing anomaly.
