Fannie Mae Benchmark CPR™ Commentary – Dec 2020

The November 30-year Benchmark CPR3 (BCPR3) for the Fannie Mae cohort decreased slightly, coming in at 34.0 CPR. That represents a 2.4% decrease from the 34.8 CPR observed in October. The driving factor for the slowdown appear to be the lower day count (by 2 days) that includes two federal holidays and weaker seasonality despite modestly lower mortgage rates and an increase in lender staffing.
