Estimation of Unexpected Operational Losses with Monte Carlo Simulation

In this paper, It can be addressed to modeling and measuring operational losses. Firstly, general ideas about operational risk are given for all of aspects then it is turned to the calculation of operational risk. The data used in paper has been created in Microsoft Excel due to the privacy of the actual data. It is applied the a frequency/severity approach with Monte Carlo Simulation which is used as a practical solution for obtaining aggregate loss distribution. All of the applications are made only to calculate expected value because for the intuitions, It’s very important to estimate expected value in terms of seeing the level of risk.
