We propose a new dynamic two-factor model of a loan portfolio. Following the common
approach, we quantify the credit risk associated with the portfolio by the probability
of default and the loss given default, each of which is driven by a factor common for all
debts in the portfolio, and a factor individual to each debt. In line with the empirical
evidence, the individual factors are assumed to be AR(1) processes. The common factors,
on the other hand, may be dependent on the external (macroeconomic) environment.
We apply our model to the US nationwide mortgage portfolio, fitting the dynamics
of the factors with a VECM model with several macroeconomic indicators as exogenous
variables.
