Prepayment speeds can be expressed in SMM (single monthly mortality), CPR (conditional prepayment rate, which is the annually compounded SMM), or PSA (percentage of the Public Securities Association prepayment model). For mortgages at least 30 months old, 100% PSA = 6.0% CPR = 0.51% SMM, equivalent to the full prepayment of 6% of a pool's ...
Variations of the model are expressed in percent, e.g., "150% PSA" means a monthly increase of 0.3% in the annualized prepayment rate, until the peak of 9% is reached after 30 months. The months thereafter have a constant annualized prepayment rate of 9%. 1667% PSA is roughly equivalent to 100% prepayment rate in month 30 or later.
A mortgage-backed security (MBS) is a type of asset-backed security (an "instrument") which is secured by a mortgage or collection of mortgages. The mortgages are aggregated and sold to a group of individuals (a government agency or investment bank) that securitizes, or packages, the loans together into a security that investors can buy.
Many American CMBS transactions carry less prepayment risk than other MBS types, thanks to the structure of commercial mortgages. Commercial mortgages often contain lockout provisions (typically a period of 1–5 years [ 2 ] where there can be no prepayment of the loan) which they can be subject to defeasance , yield maintenance and prepayment ...
Under a typical subprime mortgage made during the housing boom, a $500,000 loan at a 5.5% interest rate for 30 years results in a monthly principal and interest payment of approximately $2,839.43. In contrast, the same loan at 8.5%, under a typical 3% adjustment cap for 27 years (after the adjustable period ends), results in a payment of about ...
In addition, Fannie MBS, like those of Freddie Mac MBS and Ginnie Mae MBS, are eligible to be traded in the "to-be-announced" or "TBA" market. [63] By purchasing the mortgages, Fannie Mae and Freddie Mac provide banks and other financial institutions with fresh money to make new loans. This gives the United States housing and credit markets ...
Because interest rate caps/floors are equivalent to bond puts and calls respectively, the above analysis shows that caps and floors can be priced analytically in the Hull–White model. Jamshidian's trick applies to Hull–White (as today's value of a swaption in the Hull–White model is a monotonic function of today's short rate). Thus ...
