Mortgage Duration

The number of years until an investor receives the present value of all income from a mortgage-backed security (including interest and principal). It is used to gauge a mortgage-backed security's sensitivity to interest rate changes. The longer a mortgage duration is, the more an MBS declines in value when interest rates rise, and the more it rises when they fall.
