BASEL II REQUIREMENTS FOR OPERATIONAL RISK

Simply speaking, operational risks are the risks originating from the firm’s operational processes. Operational risk is the risk of suffering losses in processes caused by inadequacies or failures or insufficient quality in the organisation, technology, knowledge, staff, infrastructure, control function or other resources. The higher a possible loss will occur, the higher the operational risk.

With Basel II, operational risk is now subject to regulatory review: (a) the management of operational risk needs to fulfil qualitative requirements; (b) there will be a capital charge for operational risk similar to capital charges of both credit risk and market risk. With these, Basel II seems to pursue the following goals: (a) operational risk in banks should be adequately managed and (b) banks must be able to cover large operational risk losses through equity capital.

According to the current regulatory requirements, banks should:

  • assess their operational risks;

  • collect their losses caused by operational risks;

  • implement operational risk indicators; and

  • calculate and set aside risk capital.
