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 consider the modelling of credit migration risk and the pricing of migration derivatives. This enlarges the traditional setup where credit risk is based on a specificate migration state, i.e. the default one. To construct a Point-in-Time rating migration matrix as underlying value for the...

In this thesis I develop a model for describing the dynamic behavior of Credit Migration Matrices under a Point-in-time Rating Philosophy. Characteristics of the yearly Migration Matrices following a Point-in-Time Philosophy are presented. Through the introduction of the concept of Rating...
