Hi all,
I was wondering if there could be a shortcut to valuing bonds with embedded options on an interest rate tee and would like some input:
Let’s say the coupon rate is 5% on a callable (at par) three year bond. If I look at the interest rate tree, can I always assume that the bond will be called (ergo value will be par at that node) whenever the interest rate is below the coupon rate because in that case the bond will be trading above par?
This would make calculations quicker, as you will only need to calculate the value at time step t where i > c.
Any thoughts on this?
