Chapter 5 Bonds, Bond Prices and the Determination of Interest Rates Instructor’s Manual t/a Cecchetti: Money, Banking, and Financial Markets Probability of Default = 100% - 84.7% = 15.3% 6. The Transxians do, in fact, default. As a result, investors become more attuned to the chances that other small emerging-market economies may default, and immediately move to reduce their exposure to them. Describe the consequences of this increase in risk aversion for the prices of both low-risk bonds and riskier emerging-market bonds. Answer: Investors will want to shift their money into relatively low-risk bonds. The demand for emerging-market bonds shifts left, which causes prices to fall and yields to rise. The demand for low-risk bonds shifts right, increasing prices and reducing yields. 7. A 10-year zero-coupon bond has a yield of 6 percent. Through a series of unfortunate circumstances, expected inflation rises from 2 percent to 3 percent. a. Compute the change in the price of the bond. b. Suppose that expected inflation is still 2 percent, but the probability that it will move to 3 percent has risen. Describe the consequences for the price of the bond. Answer: a. Price (with 2% expected inflation) = 100/(1.06)10 = $55.84 Price (with 3% expected inflation) = 100/(1.07)10 = $50.83 The price has fallen by $5.01 b. There is increased inflation risk. Investors will require compensation for taking on additional risk, so the price will fall and the yield will rise. 8. Assume that forecasts for the U.S. economy have taken a sudden turn for the worse. Everyone had expected healthy growth of 3-4 percent in the coming year, but now a recession is predicted, with output contracting by as much as 2 percent. Officials expect unemployment to rise and corporate profits to plummet. Describe the consequences for prices and interest rates for both government and private-sector bonds. Consider both the supply and demand effects. Use graphs to support your answer. Answer: Corporations will be more likely to default during the impending recession, so the perceived riskiness of corporate bonds relative to government bonds has increased and demand for corporate bonds will shift left. It will also become more difficult for corporations to borrow, shifting the supply of corporate bonds to the left. This combination could cause prices of corporate bonds to increase or decrease. (See figure 6.6)

Chapter 5 Bonds, Bond Prices and the Determination of Interest RatesBecause the perceived riskiness of corporate bonds has increased, demand forlow-risk government bonds will increase, which will cause prices of governmentbonds to rise and prices to fall.(See figure 6.4)9.What impact woulda stock-market collapse have on bonds?Why?Answer:Theperceivedriskinessofbondsrelativetostockswouldfall and investorswould shift their money into bonds.Demand for bonds would shift right, causingprices to rise and yields to fall.10.

Chapter 5 Bonds, Bond Prices and the Determination of Interest Rates Instructor’s Manual t/a Cecchetti: Money, Banking, and Financial Markets Because the perceived riskiness of corporate bonds has increased, demand for low-risk government bonds will increase, which will cause prices of government bonds to rise and prices to fall. (See figure 6.4) 9. What impact would a stock-market collapse have on bonds? Why? Answer: The perceived riskiness of bonds relative to stocks would fall and investors would shift their money into bonds. Demand for bonds would shift right, causing prices to rise and yields to fall. 10. The government proposes cutting taxes on investment by implementing a credit for investment in information technology equipment. The proposal would reduce government tax revenues. Describe the likely impact on the bond market. Answer: Firms would have an incentive to increase their investments; they would borrow more, shifting the supply of corporate bonds to the right, which would decrease prices and raise yields. Because government tax revenues have fallen, the government will need to borrow more. This will shift the supply of government bonds to the right, decreasing prices and raising yields. 11. Other musicians, among them Rod Stewart, James Brown, and Dusty Springfield, have issued bonds similar to those created by David Bowie (as described in the article in the chapter). What is likely to make such bond issues successful? Answer: Because the success of these artists is uncorrelated with any financial markets, investors see these bonds as an opportunity to reduce their overall risk through diversification. 12. Use supply and demand in the bond market to explain each of the following news headlines. Show in a diagram what shifts and explain why. a. “Treasury prices fell for the sixth time in seven sessions as investors made room for new debt issues.” b. “Government bonds continued their month-long rise as data indicated that the U.S. economy is still progressing, but at a moderate pace.” c. “U.S. Treasurys rise sharply as stocks take dive.” d. “Treasury prices are rising on expected future rate cut.” e. “Illiquidity is crippling bond world.” Answer. a. The supply of bonds has increased, causing prices to fall

As you read the morning paper, you come across an ad for a bond mutual fund, a fund that pools the investments from a large number of people and then purchases bonds, giving the individuals “shares” in the fund. The company claims the fund has had a return of 13½ percent over the last year. But you remember that interest rates have been pretty low, 5 percent at most. A quick check of the numbers in the business section you’re holding tells you that your recollection is correct. Explain the logic behind the mutual fund’s claim in the ad. Answer: There are two possible explanations for the high return. The first is that the mutual fund is so much higher than the risk-free rate it must mean that they are investing in relatively risky bonds (and are being compensated for taking on this risk with higher returns). The second is that the fund was holding bonds during a period when interest rates were falling, so the holding period return far exceeded the interest rate. Remember that when interest rates fall, the prices of bonds rise giving the owner a capital gain. If interest rates are now low, then the likelihood is that they will rise, causing a capital loss to the owners. Chances are that the high return is a consequence of the interest rate decline, so not only will it not be repeated, it is likely to be followed by a low or even negative return when interest rates rise. 14. Your Financial World: Interest-Only Mortgages describes the monthly payments a person would have to make under various circumstances. Show how to derive the results in parts a-c if you borrow $400,000 at an annual interest rate of 6 percent: a. An interest-only mortgage requires a payment of $1,947 a month. b. A 30-year, fixed-rate mortgage requires 360 equal payments of $2,357. c. A 25-year fixed-rate mortgage requires 300 equal payments $2,538. Note: To answer these questions you will need to compute the monthly compound interest rate and use the formulas in the Appendix 4. Answer: a. (1.06 1) 0.0048676 12 1 = = m i
