RT Journal Article SR Electronic T1 How Well Do Constant-Maturity Treasures Approximate the On-the-Run Term Structure? JF The Journal of Fixed Income FD Institutional Investor Journals SP 35 OP 45 DO 10.3905/jfi.2000.319270 VO 10 IS 2 A1 James V. Jordan A1 Sattar A. Mansi YR 2000 UL https://pm-research.com/content/10/2/35.abstract AB The on-the-run term structure is generally estimated from yields on securities that sell at or near their par values. These yields can be obtained either from market data or from published estimates of par yields, known as constant-maturity Treasury yields. The authors compare the use of constant-maturity yields as an alternative to actual yields observed in the Treasury market. For a sample of month-end data covering the period January 1, 1990, through December 31, 1997, they find that constant-maturity Treasury yields produce a significantly greater pricing errors in term structure estimation than market Treasury yields both in-sample and out-of-sample. The results also suggest that the Treasury Department can improve its estimation of constant-maturity yields by using a continuous bootstrapping methodology based on an assumed functional form.
