We also have to consider that a bank has assets higher than its capital so any loss would cause a higher loss of equity for the bank, and it is not in the best interest of the central bank to cause high losses of equity to the firms making up its banking system. Therefore, if the asset has an interest rate of 3.00% a high central bank rate would be 2.50% without causing a leveraged loss of capital to the bank.
Furthermore, we must also consider that a bank's assets surpass its capital, so any decline would lead to a more significant decline in equity for the bank, and it is not in the best interest of the central bank to cause substantial losses of equity to the firms within its banking system. Therefore, if the asset has an interest rate of 3.00%, a high central bank rate would be 2.50% without resulting in a leveraged loss of capital for the bank.
