Hazard Rate Bootstrapping for CDS Indices

March 8th, 2017, 3:23 am

Hi All,
I know how to bootstrap hazard rate for a standard CDS using a CDS spread term structure.  When I am looking to bootstrap hazard rate for a CDX index lets say CDX NA IG 25 10 yr index, what is the right way to come up with the hazard rates.
1) Do I just use the spread for the above index and a tenor = 10 - valuation date ; or
2) Should I use a term structure of CDXNAIG25 index, so using 3y,5y,7y, and 10y spreads and then bootstrap hazard rates for a regular CDS. If I were to go this route, I would have to adjust the tenors by -> tenor- valuation date, right ?
When I looked at Markit Standard Calculator online, it just creates a flat spread credit curve, in accordance with ISDA model.
https://www.markit.com/markit.jsp?jsppage=pv.jsp
So I am confused as to why the tenor is not changed as CDXNAIG25 7y tenor doesnt mean 7 years to maturity from valuation date, It is 7yrs to maturity from its inception date. 
Any guidance as to where my thinking is flawed is much appreciated.

Thanks

Have you figured out this? I feel using flat hazard curve, a.k.a convention spread would be good enough.
