Mapping base correlations between bespoke and<br />
index portfolios<br />
<br />
Given a base correlation surface ρ Ι<br />
(X,T), can we determine ρ Β<br />
(X,T)<br />
Idea is to find an equivalent base tranche on a standard index with strike X I<br />
X<br />
a<br />
B<br />
X I<br />
<br />
This mapping gives the bespoke base correlations:<br />
