Part 4: Callable Bonds Now, let's consider the pricing of callable bonds. We will compare this with non-callable bonds 1. Using the tree from Part 3, calculate the value of a 1.5-year bond with a coupon rate of 3% (coupons paid semi-annually) that is callable at $100 at each coupon date (starting at t 0.5) just after the coupon is paid. Recall that a callable bond price is equal to 2. Add 0.001 to all of the interest rates in the tree from Part 3. Calculate the price of 3. Subtract 0.001 from all of the interest rates in the tree from Part 3. Calculate the price 4. Using the callable bond prices in (1), (2), and (3), calculate the modified duration of an equivalent non-callable bond price minus the value of the call the callable bond in (1) using this tree. of the callable bond in (1) using this tree. the callable bond using MD 2 x Ay 5. Calculate the modified duration of the non-callable version of the 1.5-year bond. You should already have the prices you need for this in (1), (2), and (3) Part 4: Callable Bonds Now, let's consider the pricing of callable bonds. We will compare this with non-callable bonds 1.
