Semi-Closed Solutions in Yield Curve Attribution

$25.00

We extend our model for yield curve attribution, which was recently introduced in “A New Empirical Model for Yield Curve Attribution” (Vieira, 2011), to derive a formula for the yield return that is not based on a linear approximation. We preform new derivations for the formulas of roll, shift, and twist returns that eliminate all summations so that equations are simpler and more transparent.  Finally, we do a historical analysis of the return components for a five-year period and show that the shift and yield returns are responsible for most of the treasury returns, whereas the roll, twist and shape returns have a much smaller contribution.
