OBSERVATION: Speeds continued to inch up this month, consistent with the small drop in mortgage rates. Speeds remain relatively flat for all coupons below 5%, are up slightly for the 5s, and have increased materially for coupon tranches at or above 6.0%.
The average coupon of all loans outstanding in this database ($5.87) is 4.24%, and 83% of all mortgages carry coupons under 6.00%. However, four dynamics are beginning to emerge:
The wild card now is whether the Fed’s easing will continue and, if so, what impact that will have on longer-term rates (i.e., mortgages). Additionally, the data indicates that mortgagors with coupons below 3.0% are not succumbing to demographic pressures and refinancing into higher-cost mortgages. In 2023, 34% of borrowers had mortgages below 3.0%; that percentage remains 34% today. These borrowers are holding onto their once-in-a-lifetime rates and not letting go. It will be interesting to see whether this trend continues.
