同学您好
When rates fall - MBS will be refinanced. That means the issuer of the MBS gets returned the entire funds invested and he has to reinvest those at the lower rates.
In addition, he does not get the full “interest” that he was supposed to have received as a result of the refinancing. - this causes the contingent claim risk.
