Mortgage constant prepayment rate
The prepayment rate of a mortgage pool may be expressed in a number of different ways. These measures are equally valid,although a particular method may be more useful in a given instance. a. The SMM (Single Monthly Mortality) rate of a mortgage pool is the percentage of the mortgage loans outstanding at the beginning of a month assumed to terminate during multiple or a fraction of PSA. (Colloquially, the prepayment rate is often called the prepayment speed, or simply the speed.) From the above example, given that the CPR for the 60th month is 9 percent, the PSA speed for that month is 9%/6% ¼ 150% PSA. However, if the 9 percent CPR occurs for the 20th month, then the speed would be 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%. The PSA model assumes increasing prepayment rates for the first 30 months and then constant prepayment rates afterward. The standard model, which is also referred to as 100% PSA or 100 PSA, assumes that prepayment rates will increase by 0.2% for the first 30 months until they peak at 6% in month 30. Notably, Prepayment risk is the risk associated with the early unscheduled return of principal on a fixed-income security . Some fixed-income securities, such as mortgage-backed securities, have embedded Single Monthly Mortality - SMM: In mortgage-backed securities (MBSs), this is the percentage of the principal amount of mortgages that are prepaid in a given month.

Single Monthly Mortality - SMM: In mortgage-backed securities (MBSs), this is the percentage of the principal amount of mortgages that are prepaid in a given month. For investors of MBSs The conditional prepayment rate (CPR) is a method of projecting prepayments for a pool of mortgages each month for the remainder of the mortgage’s lifespan. CPR is an annual rate. The pool of loans refers to mortgage-backed securities in the secondary market. Constant prepayment rate (CPR) (aka conditional prepayment rate), is the compounded percentage of the loan pool that is expected to prepay in the coming year. Home-equity loans (HELs) and student loans are based on this model. CPR = Annualized Rate of Monthly Prepayments / Outstanding Balance at Beginning of Period. Prepayment forces the buyer to reinvest the principal, often at a lower rate of return. Changes in interest rates certainly account for most prepayment risk, as anyone who has ever refinanced into a lower-rate mortgage can understand. But interest rate changes alone can't fully predict prepayment activity. Chart 1 also illustrates how prepayment rates (left axis) generally move in the opposite direction of the 30-year mortgage rate (right axis), illustrating how declines in mortgage rates generally lead to faster prepayment rates and vice versa. Chart 2 illustrates the comparison of pool loan-origination years for a given TBA-eligible MBS coupon.
Our models for both the conditional claim and prepayment rates do not attempt to forecast loan terminations during The definition of LTV categories is constant across all loan types. available contract rate on a fixed rate, 30-year mortgage.
A conditional prepayment rate (CPR) indicates a loan prepayment rate at which a pool of loans, such as a mortgage backed security's (MBS), outstanding principal is paid off. Another specification that has been used is the constant prepayment rate (CPR), also known as the "conditional prepayment rate." This specification assumes that the percentage of the principal However, since the mortgage payments happen monthly, we need to calculate the monthly prepayment rate. SMM is a measure of the monthly mortgage prepayment rate of the security’s mortgage pool. Let’s take an example to understand how SMM can be calculated. Assume that the outstanding loan is $100,000, Constant prepayment rate (CPR) (aka conditional prepayment rate), is the compounded percentage of the loan pool that is expected to prepay in the coming year. Home-equity loans (HELs) and student loans are based on this model. CPR = Annualized Rate of Monthly Prepayments / Outstanding Balance at Beginning of Period.
