What is the duration of a five - year, $ 1 , 0 0 0 Treasury bond with a 1 0 percent semiannual coupon selling

What is the duration of a five-year, $1,000 Treasury bond with a 10 percent semiannual coupon selling at par? Selling with a YTM of 12 percent? 14 percent? What can you conclude about the relationship between duration and yield to maturity? Plot the relationship. Why does this relationship exist?
Five-year Treasury Bond
Par value = $1,000 Coupon =0.10 Semiannual payments
YTM =0.10 Maturity =5
Time Cash Flow PVIF PV of CF PV*CF*T
0.5 $50.000.95238 $47.62 $23.81 PVIF =1/(1+YTM/2)^(Time*2)
1 $50.000.90703 $45.35 $45.35
1.5 $50.000.86384 $43.19 $64.79
2 $50.000.8227 $41.14 $82.27
2.5 $50.000.78353 $39.18 $97.94
3 $50.000.74622 $37.31 $111.93
3.5 $50.000.71068 $35.53 $124.37
4 $50.000.67684 $33.84 $135.37
4.5 $50.000.64461 $32.23 $145.04
5 $1,050.000.61391 $644.61 $3,223.04
Price = $1,000.00
Numerator = $4,053.91 Duration =4.0539= Numerator/Price
2. Consider three Treasury bonds which each have 10 percent semiannual coupons and trade at par.
Calculate the duration for a bond that has a maturity of 4 years, 3 years, and 2 years?
Please see the calculations on the next page.
a. Four-year Treasury Bond
Par value = $1,000 Coupon =0.10 Semiannual payments
YTM =0.10 Maturity =4
Time Cash Flow PVIF PV of CF PV*CF*T
0.5 $50.000.952381 $47.62 $23.81 PVIF =1/(1+YTM/2)^(Time*2)
1 $50.000.907029 $45.35 $45.35
1.5 $50.000.863838 $43.19 $64.79
2 $50.000.822702 $41.14 $82.27
2.5 $50.000.783526 $39.18 $97.94
3 $50.000.746215 $37.31 $111.93
3.5 $50.000.710681 $35.53 $124.37
4 $1,050.000.676839 $710.68 $2,842.73
Price = $1,000.00
Numerator = $3,393.19 Duration =3.3932= Numerator/Price
b. What conclusions can you reach about the relationship of duration and the time to maturity? Plot the relationship.
3. You have discovered that the price of a bond rose from $975 to $995 when the YTM fell from 9.75 percent to 9.25 percent. What is the duration of the bond?
4. Calculate the duration of a 2-year, $1,000 bond that pays an annual coupon of 10 percent and trades at a yield of 14 percent. What is the expected change in the price of the bond if interest rates decline by 0.50 percent (50 basis points)?
5. The following balance sheet information is available (amounts in $ thousands and duration in years) for a financial institution:
Amount Duration
T-bills $900.50
T-notes 550.90
T-bonds 176 x
Loans 2,7247.00
Deposits 2,0921.00
Federal funds bought 2380.01
Equity 715
Treasury bonds are 5-year maturities paying 6 percent semiannually and selling at par.
a. What is the duration of the T-bond portfolio? 4.393 years as shown below.
Treasury Bond
Par value = $176 Coupon =0.06 Semiannual payments
YTM =0.06 Maturity =5
Time Cash Flow PVIF PV of CF PV*CF*T
0.5 $5.280.97087 $5.13 $2.56
1 $5.280.94260 $4.98 $4.98
1.5 $5.280.91514 $4.83 $7.25
2 $5.280.88849 $4.69 $9.38
2.5 $5.280.86261 $4.55 $11.39
3 $5.280.83748 $4.42 $13.27
3.5 $5.280.81309 $4.29 $15.03
4 $5.280.78941 $4.17 $16.67
4.5 $5.280.76642 $4.05 $18.21
5 $181.280.74409 $134.89 $674.45.
Price = $176.00
Numerator = $773.18 Duration =4.3931= Numerator/Price
b. What is the average duration of all the assets?
c. What is the average duration of all the liabilities?
d. What is the leverage-adjusted duration gap? What is the interest rate risk exposure?
e. What is the forecast impact on the market value of equity caused by a relative upward shift in the entire yield curve of 0.5 percent [i.e.,R/(1+R)=0.0050]?
The market value of the equity will change by the following:
f. If the yield curve shifted downward by 0.25 percent (i.e.,R/(1+R)=-0.0025), what is the forecasted impact on the market value of equity?
g. What variables are available to the financial institution to immunize the balance sheet? How much would each variable need to change to get DGAP equal to 0?
