Methods of quantifying operational risk in Banks : Theoretical approaches

The definition of operational risk is a challenge. This risk has an atypical character as far as it concerns all the activities of the bank. It is also often difficult to estimate it independently of the other risks which characterizes the banking activity. Indeed, it is very difficult to determine the amount, the frequency, and the key factors behind this risk. Banks are still putting in place procedures of data collection and formalized approaches in this area. This is what we try to decipher. How then banks are they supposed to assess, predict and effectively manage operational risk, given the incredible diversity of dangers and threats now facing their business? How can they successfully respond to new constraints emanating from regulatory authorities while preserving their future profitability? These two questions are at the heart of the issues related to the measurement of operational risk, and are not without effect on the future ability of banks to manage this type of risk.
