Well that’s the difference between MBS and regular bonds, but I recall from L1 that some bonds are amortizing as well.
If a bond is called, it’s essentially a prepayment, just like an MBS.
I was asking because I was reading “There are two types of contingent claims risks: 1) Call risk, and 2) prepayment risk”
I started thinking, oh boy, I would only have been able to come up with one risk on the exam, because to me, a prepayment is essentially the same as call risk. It’s feels like saying that there are two kinds of music - country, and western.
