For example, cash, deposits in other banks and financial instruments issued by the Central Bank of Chile have 0% risk, which means that, according to current standards, no capital is required to back these assets. Properties and equipment have a 100% risk, which means that they must have a minimum capital equivalent to 8% of the amount of these assets and in the case of the Bank of Chile 10%. |
