Final answer:
The increase in the discount rate from 7% to 9% following the issuance of a 3-year maturity loan results in a decline in the value of the loan due to a higher present value discount rate, making option (d) Declines by 5.4% the correct answer.
Step-by-step explanation:
When the discount rate on a loan increases, it affects the present value of the future payments that the borrower needs to make. In the event of a loan being made with a 3-year maturity at a 7% discount rate and then the rate increases to 9%, the value of the loan declines. This is because the present value of the loan's future repayments, now being discounted at a higher interest rate, decreases, similar to how the value of a bond would drop if the interest rates increased post-purchase. Thus, the increase in the discount rate from 7% to 9%, in this scenario, would result in a decline in the value of the loan. Therefore, among the options provided, the correct answer would be (d) Declines by 5.4%.
