Abstract: This paper describes a pilot project for peer benchmarking of operational risk scenarios. By using a common methodology of scenario design and quantification, this project offers banks a tool for mutual comparison of risk level and risk drivers. The intent is not to replace internal methods of scenario assessment, but to supplement them with a benchmarking tool. Eight US banks participated in the pilot project. The group used the eXposure, Occurrence and Impact (XOI) methodology, which combines Bayesian networks and Monte Carlo simulation to design and assess scenarios. Results and individual drivers have been compared between peers for each scenario. In the first section of this paper, we explain the need for scenario assessment. The second section describes the XOI method in detail. The third section presents the pilot experiment and lessons learned.
