On Operational Risk Stress Testing

Yakov Lantsman, Sabeth Siddique and Yan Shi

This chapter will introduce operational risk and its evolution, as well as common industry practices in operational risk management. It will start by providing a brief background of operational risk and stress testing, followed by a systematic overview of the structures of supervisory and bank idiosyncratic scenarios. Common and useful methodologies in the construction of bank idiosyncratic scenarios will then be articulated. Related post-operational risk calculation work, such as the operational risk model capital buffer, reporting and effective challenge, will be addressed in the final section.
