Solutions for End-of-Chapter Questions and Problems: Chapter Seven

1. What is the process of asset transformation performed by a financial institution? Why does this process often lead to the creation of interest rate risk? What is interest rate risk?

Asset transformation by an FI involves purchasing primary assets and issuing secondary assets as a source of funds. The primary securities purchased by the FI often have maturity and liquidity characteristics that are different from the secondary securities issued by the FI. For example, a bank buys medium- to long-term bonds and makes medium-term loans with funds raised by issuing short-term deposits.

Interest rate risk occurs because the prices and reinvestment income characteristics of long-term assets react differently to changes in market interest rates than the prices and interest expense characteristics of short-term deposits. Interest rate risk is the effect on prices (value) and interim cash flows (interest coupon payment) caused by changes in the level of interest rates during the life of the financial asset.

2. What is refinancing risk? How is refinancing risk part of interest rate risk? If an FI funds long-term fixed-rate assets with short-term liabilities, what will be the impact on earnings of an increase in the rate of interest? A decrease in the rate of interest?

Refinancing risk is the uncertainty of the cost of a new source of funds that are being used to finance a long-term fixed-rate asset. This risk occurs when an FI is holding assets with maturities greater than the maturities of its liabilities. For example, if a bank has a ten-year fixed-rate loan funded by a 2-year time deposit, the bank faces a risk of borrowing new deposits, or refinancing, at a higher rate in two years. Thus, interest rate increases would reduce net interest income. The bank would benefit if the rates fall as the cost of renewing the deposits would decrease, while the earning rate on the assets would not change. In this case, net interest income would increase.

3. What is reinvestment risk? How is reinvestment risk part of interest rate risk? If an FI funds short-term assets with long-term liabilities, what will be the impact on earnings of a decrease in the rate of interest? An increase in the rate of interest?

Reinvestment risk is the uncertainty of the earning rate on the redeployment of assets that have matured. This risk occurs when an FI holds assets with maturities that are less than the maturities of its liabilities. For example, if a bank has a two-year loan funded by a ten-year fixed-rate time deposit, the bank faces the risk that it might be forced to lend or reinvest the money at lower rates after two years, perhaps even below the deposit rates. Also, if the bank receives periodic cash flows, such as coupon payments from a bond or monthly payments on a loan, these periodic cash flows will also be reinvested at the new lower (or higher) interest rates. Besides the effect on the income statement, this reinvestment risk may cause the realized yields on the assets to differ from the a priori expected yields.
4. The sales literature of a mutual fund claims that the fund has no risk exposure since it invests exclusively in federal government securities that are free of default risk. Is this claim true? Explain why or why not.

Although the fund's asset portfolio is comprised of securities with no default risk, the securities remain exposed to interest rate risk. For example, if interest rates increase, the market value of the fund's Treasury security portfolio will decrease. Further, if interest rates decrease, the realized yield on these securities will be less than the expected rate of return because of reinvestment risk. In either case, investors who liquidate their positions in the fund may sell at a Net Asset Value (NAV) that is lower than the purchase price.

5. What is economic or market value risk? In what manner is this risk adversely realized in the economic performance of an FI?

Economic value risk is the exposure to a change in the underlying value of an asset. As interest rates increase (or decrease), the value of fixed-rate assets decreases (or increases) because of the discounted present value of the cash flows. To the extent that the change in market value of the assets differs from the change in market value of the liabilities, the difference is realized in the market value of the equity of the FI. For example, for most depository FIs, an increase in interest rates will cause asset values to decrease more than liability values. The difference will cause the market value, or share price, of equity to decrease

6. A financial institution has the following balance sheet structure:

Assets Liabilities and Equity
Cash $1,000 Certificate of Deposit $10,000
Bond $10,000 Equity $1,000
Total Assets $11,000 Total Liabilities and Equity $11,000

The bond has a 10-year maturity and a fixed-rate coupon of 10 percent. The certificate of deposit has a 1-year maturity and a 6 percent fixed rate of interest. The FI expects no additional asset growth.

a. What will be the net interest income (NII) at the end of the first year? Note: Net interest income equals interest income minus interest expense.

Interest income $1,000 $10,000 x 0.10
Interest expense 600 $10,000 x 0.06
Net interest income (NII) $400

b. If at the end of year 1 market interest rates have increased 100 basis points (1 percent), what will be the net interest income for the second year? Is the change in NII caused by reinvestment risk or refinancing risk?

Interest income $1,000 $10,000 x 0.10
Interest expense 700 $10,000 x 0.07
Net interest income (NII) $300

The decrease in net interest income is caused by the increase in financing cost without a corresponding increase in the earnings rate. Thus, the change in NII is caused by refinancing risk. The increase in market interest rates does not affect the interest income because the bond has a fixed-rate coupon for ten years. Note: this answer makes no assumption about reinvesting the first year’s interest income at the new higher rate.

c. Assuming that market interest rates increase 1 percent, the bond will have a value of $9,446 at the end of year 1. What will be the market value of the equity for the FI? Assume that all of the NII in part (a) is used to cover operating expenses or is distributed as dividends.

Cash $1,000 Certificate of deposit $10,000
Bond $9,446 Equity $ 446
Total assets $10,446 Total liabilities and equity $10,446

d. If market interest rates had decreased 100 basis points by the end of year 1, would the market value of equity be higher or lower than $1,000? Why?

The market value of the equity would be higher ($1,600) because the value of the bond would be higher ($10,600) and the value of the CD would remain unchanged.

e. What factors have caused the change in operating performance and market value for this firm?

The operating performance has been affected by the changes in the market interest rates that have caused the corresponding changes in interest income, interest expense, and net interest income. These specific changes have occurred because of the unique maturities of the fixed-rate assets and fixed-rate liabilities. Similarly, the economic market value of the firm has changed because of the effect of the changing rates on the market value of the bond.

7. How does the policy of matching the maturities of assets and liabilities work (a) to minimize interest rate risk and (b) against the asset-transformation function for FIs?

A policy of maturity matching will allow changes in market interest rates to have approximately the same effect on both interest income and interest expense. An increase in rates will tend to increase both income and expense, and a decrease in rates will tend to decrease both income and expense. The changes in income and expense may not be equal because of different cash flow characteristics of the assets and liabilities. The asset-transformation function of an FI involves investing short-term liabilities into long-term assets. Maturity matching clearly works against successful implementation of this process.
8. Corporate bonds usually pay interest semiannually. If a company decided to change from semiannual to annual interest payments, how would this affect the bond’s interest rate risk?

The interest rate risk would increase as the bonds are being paid back more slowly and therefore the cash flows would be exposed to interest rate changes for a longer period of time. Thus any change in interest rates would cause a larger inverse change in the value of the bonds.

9. Two 10-year bonds are being considered for an investment that may have to be liquidated before the maturity of the bonds. The first bond is a 10-year premium bond with a coupon rate higher than its required rate of return, and the second bond is a zero-coupon bond that pays only a lump-sum payment after 10 years with no interest over its life. Which bond would have more interest rate risk? That is, which bond’s price would change by a larger amount for a given change in interest rates? Explain your answer.

The zero-coupon bond would have more interest rate risk. Because the entire cash flow is not received until the bond matures, the entire cash flow is exposed to interest rate changes over the entire life of the bond. The cash flows of the coupon-paying bond are returned with periodic regularity, thus allowing less exposure to interest rate changes. In effect, some of the cash flows may be received before interest rates change. The effects of interest rate changes on these two types of assets will be explained in greater detail in the next section of the text.

10. Consider again the two bonds in problem (9). If the investment goal is to leave the assets untouched until maturity, such as for a child’s education or for one’s retirement, which of the two bonds has more interest rate risk? What is the source of this risk?

In this case the coupon-paying bond has more interest rate risk. The zero-coupon bond will generate exactly the expected return at the time of purchase because no interim cash flows will be realized. Thus the zero has no reinvestment risk. The coupon-paying bond faces reinvestment risk each time a coupon payment is received. The results of reinvestment will be beneficial if interest rates rise, but decreases in interest rate will cause the realized return to be less than the expected return.

11. A money market mutual fund bought $1,000,000 of two-year Treasury notes six months ago. During this time, the value of the securities has increased, but for tax reasons the mutual fund wants to postpone any sale for two more months. What type of risk does the mutual fund face for the next two months?

The mutual fund faces the risk of interest rates rising and the value of the securities falling.

12. A bank invested $50 million in a two-year asset paying 10 percent interest per annum and simultaneously issued a $50 million, one-year liability paying 8 percent interest per annum. What will be the bank’s net interest income each year if at the end of the first year all interest rates have increased by 1 percent (100 basis points)?

Net interest income is not affected in the first year, but NII will decrease in the second year.

Year 1 Year 2
Interest income $5,000,000 $5,000,000
Interest expense $4,000,000 $4,500,000
Net interest income $1,000,000 $500,000

13. What is market risk? How do the results of this risk surface in the operating performance of financial institutions? What actions can be taken by FI management to minimize the effects of this risk?

Market risk is the risk of price changes that affects any firm that trades assets and liabilities. The risk can surface because of changes in interest rates, exchange rates, or any other prices of financial assets that are traded rather than held on the balance sheet. Market risk can be minimized by using appropriate hedging techniques such as futures, options, and swaps, and by implementing controls that limit the amount of exposure taken by market makers.

14. What is credit risk? Which types of FIs are more susceptible to this type of risk? Why?

Credit risk is the possibility that promised cash flows may not occur or may only partially occur. FIs that lend money for long periods of time, whether as loans or by buying bonds, are more susceptible to this risk than those FIs that have short investment horizons. For example, life insurance companies and depository institutions generally must wait a longer time for returns to be realized than money market mutual funds and property-casualty insurance companies.

15. What is the difference between firm-specific credit risk and systematic credit risk? How can an FI alleviate firm-specific credit risk?

Firm-specific credit risk refers to the likelihood that specific individual assets may deteriorate in quality, while systematic credit risk involves macroeconomic factors that may increase the default risk of all firms in the economy. Thus, if S&P lowers its rating on IBM stock and if an investor is holding only this particular stock, she may face significant losses as a result of this downgrading. However, portfolio theory in finance has shown that firm-specific credit risk can be diversified away if a portfolio of well-diversified stocks is held. Similarly, if an FI holds well-diversified assets, the FI will face only systematic credit risk that will be affected by the general condition of the economy. The risks specific to any one customer will not be a significant portion of the FIs overall credit risk.

16. Many banks and S&Ls that failed in the 1980s had made loans to oil companies in Louisiana, Texas, and Oklahoma. When oil prices fell, these companies, the regional economy, and the banks and S&Ls all experienced financial problems. What types of risk were inherent in the loans that were made by these banks and S&Ls?

The loans in question involved credit risk. Although the geographic risk area covered a large region of the United States, the risk more closely characterized firm-specific risk than systematic risk. More extensive diversification by the FIs to other types of industries would have decreased the amount of financial hardship these institutions had to endure.

17. What is the nature of an off-
