Hi All,I am new member to this group .Looking for the below informationI need some information regarding boot strapping of hazard rate term structure from CDS spreads. I have the CDS Quotes available for 1,3,5,7,10 years and need to understand how to bootstrap the hazard rate. Its done in one of my projects but its not transparent as the logic sits within QA calls. We are given with CDS Quotes, Recovery Rate .Has any one got some excel on the same.Thanks in advance

QA Calls -- quantitative analytic library calls . These are APIs provided by the quantitative analytics team

i see. conceptually it is relatively straightforward. First you need to a model that values a CDS using hazard rates - for example I would look at the Hull paper. Once you have that, then it is a matter of implementing the usual bootstrap methodology. you could work with piecewise constant hazard rates or something fancier.

Thanks. As per Hull model we need to first calculate the Survival Probability for each year and then derive Hazard rates. How do we derive the survival probability for each year from CDS Spread ? If any one has got any excel that would be really helpful
