Bank A has 100 worth of assets (only loans for simplicity): L = 100, capital K = 60 and liabilities (only deposits for simplicity) D = 40. Similarly, Bank B has 100 worth of assets (only loans for simplicity): L = 100, but its capital is K = 40 and its liabilities (only deposits for simplicity) are D = 60. The interest rates on deposits is liabilities = 0.01. The interest rates on assets are: assets = 0.05. There are two possible outcomes for the bank’s loans, good or bad. In the good outcome, no loan defaults. Thus the interest payments on a bank’s assets are=a_ssets × L. In the bad outcome, 50% of loans default. Thus the interest payments on a bank’s assets are=0.5 a_ssets × L. Each outcome is equally likely (that is the probability of each outcome is 0.5). In any case, the interest payments on a bank’s liabilities are=l_iabilities × D.
