Economic Capital

Risk Capital Framework 

      Expected losses are budgeted and covered as expenses in the usual course of business. On the other hand, economic Capital is defined as the amount of capital needed to cover unexpected losses during extreme events. That is why, it is measured as the potential unexpected losses over a one year time period at a 99.97% confidence level.

Economic-capital Risk Capital is a consistent and comprehensive risk management tool. It is based on assessment of risk parameters: PD, EAD, LGD. Risk capital designed to reflect the amount of capital needed to cover unexpected economic losses during extreme events. It has migrated to finer segmentation in conjunction with  Basel II initiative, leverages Vasicek (Basel II) distribution assumptions and benefits from large sample sizes in retail portfolios.


    Economic Capital covers not only market, operational and credit risk but should also cover insurance risk, pension risk and any other risk identified. For practical reasons the economic capital used within the bank only includes market, operational and credit risk. Economic Capital as used in determining our capital requirements takes diversification into consideration. Economic Capital is different from Pillar 1 capital requirements calculated under the advanced methodology because the calculation is based on the different risks, different confidence levels and takes diversification factors into consideration.
