Explanation:
The bank runs the danger that just before the second year, the short-term interest rate will increase, increasing its Lending value, but leaving untouched the interest income the bank gets from either the Treasury bill.
Annual interest revenue of 0.04* $50 million= 2 million and annual interest costs for the bank (0.02)* $50 million= 1 million, between 2 per cent to 4 per cent for the Treasury note.
The bank makes a profit of $2 million – $1 million = $1 million. If the interest rate rises 1 percent, the bank’s profit falls to
((0.04)* $50 million) – ((0.03) * $50 million) = $500,000.
