13. Correlations between default and migration events

Institutions‟ IRC models should include the impact of correlations between default or migration events in a way that is consistent with their purpose, which is to capture credit risk correlations between different issuers. The assumptions on which their estimation is based should be consistent with the assumptions used in the simulation. The methodology should be documented and duly justified. The approach should be adequate and conservative enough to capture the interdependence between the risk drivers of credit risk events such as defaults and migrations. This would include, for example, the obligation that, if institutions choose to estimate their correlation parameters from the prices of traded securities, the estimates should be updated frequently.
