Author: David Roseburgh & Agata Wronka

This support note describes the Nelson-Siegel (NS) methodology for interpolating and extrapolating the nominal yield curve using the Nelson-Siegel functional form. This approach is implemented in the Nominal Rates Nelson-Siegel Yield Curve Calibration Tool. We outline the methodology and discuss its application in the context of the calibration tool.
