(RMBS)
 In US, majority of the MBSs are issued by the Government Sponsored
Enterprises like the Federal National Mortgage Association (Fannie
Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac)
and Government National Mortgage Association (Ginnie Mae). There

are guaranteed returns backed by the Federal government itself. There
are few factors that affect the MBS.
 Economic Growth : Greater economic growth accentuates the need
of large capital and it indirectly reduces the MBS prices
 Inflation: Increasing inflation can have an impact over the MBS
pricing. Inflation causes the dollar value to erode, lender demand for
more interest rate.

pass-through securities as a Ginnie Mae pass-through security.

12. Ginnie Mae Mortgage-Backed Securities

15. Conti…
 Features
 Nonagency MBSs are often guaranteed against default through
external credit enhancements, such as the guarantee of a
corporation or a bank letter of credit or by private insurance
from a monocline insurer.
 Many are also guaranteed internally through the creation of
senior and subordinate classes of bonds with different
priority claims on the pool's cash flows in the case some of the
mortgages in the pool default.
 The more subordinate claims sold relative to the senior
claims, the more secure the senior claims.
