Abstract

Considering correlations between entries of credit portfolio is an important objective when estimating credit risk. This paper aims to construct a multivariate model of credit losses examining a portfolio composed of loans to a set of kinds of business. The paper also introduces the method of credit risk calculation via copulas, gamma distribution and kernel estimates. Empirical application of the introduced method is realized by using a historical loss data provided by one of the Moscow credit banks.
