Calculating Capital Requirements for Operational Risk in Compliance with the Capital Requirements Directive IV (CRD IV)

Abstract

Operational risk is defined as the possibility of losses resulting from the failure, deficiency or inadequacy of internal processes, people and systems, or from external events. Operational risk measurement methods differ from techniques applied to other types of risk. The importance of operational risk has increased substantially in recent years due to huge losses suffered by renowned financial institutions. These led to the publication of the European Union Capital Requirements Directive (CRD), introduced by the so-called Basel II-based definition of banks' capital requirements. The main objective of the paper is to analyse the operational risk measurement methods proposed in the New Basel Capital Accord: the Basic Indicator Approach, the Standardised Approach, and Advanced Measurement Approaches (AMA). The author analysed, in successive stages of the paper, the definition and characteristics of operational risk and methods of calculating capital requirements.
