About the zero coupon yields

The individual zero coupon yields or the curve that plots these yields are often referred to as the yield term structure. The zero coupon yield curve shows an unambiguous relationship between the effective yield (yield to maturity) and term to maturity and is not affected by the fact that individual bonds are issued with differing coupons. The published zero coupon yields are estimated values based on observed effective yields on Norwegian Treasury bills (zero coupon securities) and government bonds (coupon securities).

Norges Bank calculates zero coupon yields using a parametric method developed by Nelson and Siegel and developed further by Svensson, referred to as the NSS method.
