Homogenous Credit Model

Overview

In the homogenous Vasicek model, all loans in a portfolio are drawn from a single default distribution.

Estimation of Probabilities

  • Probability of Single Default - estimating the probability of default based on history of a loan.
  • Probability of Joint Default - estimating the probability of two loans defaulting in the same period. The probability of joint default together with the probability of a single loan defaulting implies the default correlation.
