We consider the modelling of credit migration risk and the pricing of migrationderivatives. To construct a Point-in-Time (PIT) rating migration matrix as the underlyingvalue for derivative pricing we show first that the Affine Markov Chain models isnot sufficient to generate PIT migration...

We introduce a framework for analyzing the interplay between credit risk and collateralmarket risk on loan pricing. To do this, we decompose any loan into an unsecured and asecured part. Further we explicitly consider the recovery process. The framework allows usto develop semi-analytical...
