In June 2004 the Committee published a revised framework for the international convergence of capital measurement and capital standards, known as Basel II. The proposal includes a formal capital charge against operational risk in the business activities of banks. The calculation of an...

All banks must hold capital equal to the minimum regulatory requirement. However, in many cases the level of regulatory capital diverges from the actual (economic) capital held by banks. A bank's actual capital is typically linked to a target credit rating, which is in turn determined by the...

Extreme value theory (EVT) is regularly put forward by academics, practitioners and banking regulators as a methodology for measuring the likelihood of operational risk losses that have a very low probability of occurrence, but which have the potential for catastrophic outcomes in terms of...

It is somewhat ironic that while the major focus of regulators and institutions in the financial services sector over recent years has been on developing models for measuring and managing credit risk, most of the large losses in financial institutions over this time have been sourced to...
