In this study, the concept of operational risk is developing mainly in relation to banking institutions. The aim of the thesis is to identify and record the main sources of operational risk. The work also highlights the international trends in the management and measurement of risk as well as the most important incidents of recent years. Finally, the capital adequacy methods are compared and the corresponding funds for the Greek systemic banks are determined using the basic index method and the standardized method. The first chapter introduces the concepts of risk and uncertainty, the evolution of risk in the last 4 decades, the main banking risks and the need for a regulatory framework. In the second chapter we analyze the concept of operational risk initially through the Basel Framework, then through its definition and specific examples, and the link between operational risk credit risk and market risk. The third chapter presents the main sources of operational risk that can be internal or external. These sources are categorized and refer to specific cases per category. The conclusion of the third chapter is the high indirect cost of operating risk that can cost the loss of investors’ confidence as the bankruptcy of the bank. The fourth chapter concerns the measurement of the required operational risk capital, from which conclusions are drawn for the three methods proposed by the Basel Committee.
