Value-at-Risk (VaR) and Expected Shortfall (ES) are common high quantile-based risk measures adopted in financial … regulations and risk management. In this paper, we propose a tail risk measure based on the most probable maximum size of risk … events (MPMR) that can occur over a length of time. MPMR underscores the dependence of the tail risk on the risk management …

The severity function approach (abbreviated SFA) is a method of selecting adverse scenarios from a multivariate density. It requires the scenario user (e.g. an agency that runs banking sector stress tests) to specify a "severity function", which maps candidate scenarios into a scalar severity...
