Abstract
The aim of this paper is to analyze operational risk in the context of the 2007-9 financial crisis. The world's largest repository of information on publicly reported operational losses, SAS OpRisk Global Data, was chosen as the underlying dataset. We find a significant impact on the riskiness of the loss severity for the trading and sales and retail brokerage business lines (BLs) due to the financial crisis. Losses from investment banks caused by the market failure of auction rate securities are responsible for this result. Thus, we compute a 150% higher valueat- risk (VaR) for the BL trading and sales and a 50% higher VaR for the BL retail brokerage when considering the financial crisis data. However, the other BLs are not affected by the financial crisis.
