Prepay Commentary

December MBS Prepayment Speeds

December factors are out and, like we expected last month, we saw a broad decline, one of only two this year, in prepayment speeds. This was largely expected given higher mortgage rates during the appropriate refinancing window which was approximately mid-October to mid-November. Also factoring in were fewer business days and lower turnover, a seasonal event as fewer homes are sold this time of year. Next month, I expect CPRs to be stable, relatively speaking, to this month.


Food for Thought

As prepayments increased this year, many investors, depositories in specific, sought refuge in 15-Year 2% MBS at discount prices. Unlike MBS at premium prices, yields on discount-priced MBS, are enhanced by prepayments. Given the increase in activity we have seen in 15-Year 2% MBS, I thought it would be interesting to look at prepayments broken down by state. A helpful number to keep in mind is that the national 3-month average is 9.1 CPR. Of interest, the three fastest states are Montana, Oklahoma, and New Mexico; and, the three slowest payers are Vermont, Hawaii, and the District of Columbia.

Mortgage Rates

Based on the Freddie Mac Primary Mortgage Market Survey, 30- and 15-year fixed-rate mortgage rates are 19 and 14 bps above their respective lows and are virtually unchanged since last month.
