We propose to pool alternative systemic risk rankings for financial institutions using the method of principal … components. The resulting overall ranking is less affected by estimation uncertainty and model risk.

We examine pitfalls in the use of return-based measures of systemic risk contributions (SRCs). For both linear and non …'s systematic risk, idiosyncratic risk, size or contagiousness increases the risk of the system but lowers the measured SRC of the … potentially adverse side effects: A change in a bank's risk structure can make the measured SRC of its competitors increase more …
