Except for the credit quality of the Credit Default Swap protection seller, the following relationship...

The relationship that approximates the yield on a risk-free instrument, excluding the credit quality of the Credit Default Swap (CDS) protection seller, is given by the combination of a bond and a CDS. The bond provides the base yield, and the CDS offers protection against default, together creating an instrument that mimics the characteristics of a risk-free yield by hedging against credit risk.
