Callable U.S. Treasury bonds: optimal calls, anomalies, and implied volatilities
Previous studies on interest rate derivatives have been limited by the relatively short history of most traded derivative securities. The prices for callable U.S. Treasury securities, available for the period 1926?95, provide the sole source of evidence concerning the implied volatility of interest rates over this extended period. Using the prices of callable, as well as non-callable, Treasury instruments, this paper estimates implied interest rate volatilities for the past seventy years. Our technique for estimating implied volatilities enables us to address two important issues concerning ...

To call or not to call?: optimal call policies for callable U.S. Treasury bonds
Until 1984, the U.S. Treasury typically issued its long-term bonds in callable form. A number of these securities, totaling $93.8 billion in face value, remain outstanding. After a call protection period, usually five years prior to maturity, the Treasury can call the bonds but must give prior notification of intent to call. This article develops a decision rule, which takes account of the prior notification requirement, when it is optimal to call such bonds. ; The decision of whether to call is based on the current level of interest rates and their volatility. For a call to be optimal for ...

The implied volatility of U.S. interest rates: evidence from callable U. S. Treasuries
The prices for callable U.S. Treasury securities provide the sole source of evidence concerning the implied volatility of interest rates over the extended 1926-1994 period. This paper uses the prices of callable as well as non-callable Treasury instruments to estimate implied interest rate volatilities for the past sixty years, and, for the more recent 1989-1994 period, the cross-sectional term structures of implied interest rate volatility. We utilize these estimates to perform cross-sectional richness/cheapness analysis across callable Treasuries. Inter alia, we develop the optimal call ...
