Please answer question 4. Question 3 is below for your reference.

4. Suppose your bond portfolio in the bank consists of both bonds in question 3 (see above). You have 5 million bonds in the 7.2%-coupon bonds as interest-sensitive assets, and 6 million 10%-coupon bonds as interest-sensitive liabilities. Answer the following questions;

a) Suppose the Treasury bond futures contract has the duration as 2.45 (years), how many futures contract you need to hedge the interest rate risk (assuming that the same term structure of interest rates applied to all these assets and futures)?

b) Is this hedging ratio applicable to all situations? Why or why not?

c) What is the change of Economic Value of Equity (EVE) for the bank if the term structure of interest rates interest increases with 5 basis point?

d) What are the assumptions for analysis in using change of EVE to measure interest rate risk

3. Suppose that youre given a 8-year 7.2%-coupon bond with $1,000 face value that pays the semi-annual coupon payments, the bond price in the market is $886 per bond, answer the following questions:

a) What is the yield to maturity? What is the idea of yield to maturity? Explain the difference between your bonds yield to maturity versus the term structure of interest rates.

b) Suppose you are about to apply the immunization strategy for the bond portfolio what is the optimal holding period for the bond portfolio? What are the limitations of the immunization strategy?

c) What is the convexity of a bond? Suppose the interest rate is about to change 4 basis points, what will be the change of bond price?

d) Suppose youre considering another 8-year 10%-coupon bond with $1,000 face value that pays the semi-annual payments, the bond price is $682 per bond in the market. What is the duration of this bond given that the interest rate is to change 4 basis points?

e) Is this bond subject to higher convexity or not following the same interest rate change in c)? Which bond is better in your perspective to immunize the interest rate risk? Graph your result to show their differences in convexity.

f) What are the limitations in using duration and convexity to analyze the interest rate risk for the fixed income portfolio?
