Estimated yield curve

Zero-coupon yield curve is estimated from the sovereign securities issued by Slovak republic using Nelson-Siegel-Svensson (NSS) method. Estimated zero-coupon yield curve reflects interest rates expectations over the maturity spectrum of Slovak sovereign securities market. Estimated notional yields are values adjusted for different coupons and other cash-flow conditions attached to individual security issues and estimated by using the NSS functional form.

There are two innovations compared to the methodology outlined in the manual MFSR1, First, only sovereign bonds with maturity between 6 months and 15 years enter the calculation and second, historical starting values are being used rather than those of the Bundesbank zero-coupon yield curve estimate.

Due to the change in methodology, time series before 2017 may not be fully consistent with the estimate after 1st January 2017. National Bank of Slovakia shall not be held liable for accuracy of these historical estimates.

The National Bank of Slovakia acknowledges some persistent inaccuracies in the estimated values, which originate from lower liquidity of the sovereign bond market in Slovakia, limited number of traded securities, which induces limited price observations that enter the calculation. Inaccuracies due to the above factors can accumulate up to 30 basis points on average. Values corresponding to the short end of the yield curve (maturity of less than 2 years) may be subject to higher than estimated errors. (please read further about testing inaccuracies of the market in the Analytical note from 6th of june 2017).
