چکیده

We describe a numerical procedure to obtain bounds on the distribution function of a sum of n dependent risks having fixed marginals. With respect to the existing literature, our method provides improved bounds and can be applied also to large non-homogeneous portfolios of risks. As an application, we compute the VaR-based minimum capital requirement for a portfolio of operational risk losses.

Aggregating Risk across Matrix Structured Loss Data: the Case of Operational Risk

We study the problem of evaluating the risky position involved in a matrix of random losses with some given probabilistic structure. In the Basel II regulatory setup for operational risk in banking, we analyse how interdependencies between individual loss random variables within the matrix may influence different estimates for the minimum capital charge required.

New approaches to operational risk modeling

Estimation of economic capital of a financial institution requires modeling of operational losses of the business units of the organization. Operational losses of the financial institution are usually represented as an aggregate sum of the losses incurred by the operational events of the business units. Simulation of these events requires the introduction of a co-dependence structure for a more...

An application of capital allocation principles to operational risk and the cost of fraud

The costs of operational risk refer to the capital needed to cover the losses generated by a firm’s ordinary activities. In this paper several capital allocation principles are examined to demonstrate how such principles can be used to distribute aggregated capital across the various constituents that generate operational risk. Proportional allocation, for example, allows a cost per unit to be ...

Estimation of capital requirements in the Iranian banking system To deal with market and credit risks

Each financial institution faces different types of risks, with three of the most important risks in the banking system being credit, market and operational risks. In order to manage risk, sufficient capital must be allocated. One of the common ways to calculate the capital needed to deal with these risks is to calculate the capital proportional to each risk and then the algebraic sum to obtain...

Modeling the operational risk in Iranian commercial banks: case study of a private bank

The Basel Committee on Banking Supervision from the Bank for International Settlement classifies banking risks into three main categories including credit risk, market risk, and operational risk. The focus of this study is on the operational risk measurement in Iranian banks. Therefore, issues arising when trying to implement operational risk models in Iran are discussed, and ...
