Risk Management in Corporate Loan Portfolio - Default Correlation
(2011) NEKM07 20111Department of Economics
- Abstract
- Purpose:
The purpose of this paper is to estimate different industries’ default rate correlation over time. The intention is to observe if banks have any diversification opportunities in their corporate loan portfolio and to what extent this may disappear in stressful economic situations.
Methodology:
In this paper, the dynamic conditional correlation model is applied to analyze the default correlation structure over time in four Swedish corporate industries. The model applied has the characteristics of being equally flexible as univariate GARCH but not as complex as multivariate GARCH.
Results:
The findings of this paper suggest that the default correlation over time is fairly low which gives a bank some diversification... (More) - Purpose:

Results:
The findings of this paper suggest that the default correlation over time is fairly low which gives a bank some diversification opportunity in their corporate loan portfolio. However, in times of economic distress, hence, when default rates are high, the correlations increase significantly. This is discussed to be very unfavorable from a risk management perspective since the correlations break down when needed the most. (Less)
