Under the new Capital Accord, banks choose between two different types of risk management systems, the standard or the internal rating based approach.

We propose a credit portfolio approach for evaluating systemic risk and attributing it across institutions. We construct a model that can be estimated from high-frequency CDS data. This captures risks from privately held institutions and cooperative banks, extending approaches that rely on...
