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...

The local Hurst exponent, a measure employed to detect the presence of dependence in a time series, may also be used to investigate the source of intraday variation observed in the returns in foreign exchange markets. Given that changes in the local Hurst exponent may be due to either a...

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...

This paper develops a framework for examining the impact of changes in the solvency standard of a bank (target credit rating) on the pricing of bank assets. We show that the decision of a bank to increase its solvency standard increases the price of bank assets to the extent that a bank prices...

Within the context of a banking institution, economic capital is a statistical measure of the amount of resources required to meet unexpected losses over a specified time period and specified level of certainty. The amount of economic capital held by banks is thus a function of their target...

In June 2004 the Basel Committee on Banking Supervision of the Bank for International Settlements issued its revised framework for the international convergence of capital measurement and capital standards. In developing the framework the Committee has sought to determine risk-sensitive capital...

An increase in the credit rating on an organisation?s debt is generally perceived positively, as higher credit ratings are, in the main, associated with lower perceived volatility in the market value of the assets of the entity that has issued the debt. If banks price their assets to realise a...

In this paper, we propose a unified framework for trust management that can cover a broad variety of trust mechanisms including reputations, credentials, local data and environment parameters. The proposed trust management framework leverages established standards and it covers a broad variety...

As a learning theory, the continuous improvement (CI) discourse has benefited countless manufacturing enterprises to improve and adapt their methods of production. As one of the pillars of total quality management, it has generally included a range of dynamic concepts from high involvement...
