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.
Additionally, we must take into account that a bank possesses assets exceeding its capital, so any loss would result in a greater loss of equity for the bank, and it is not in the best interest of the central bank to inflict high losses of equity on the firms comprising its banking system. Consequently, 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.
