The 10-year Treasury yield stood at 4.56% on July 15, 2026, while the 30-year mortgage rate averaged 6.51%, producing a 1.95% spread that remains near recent highs.
As of July 15, 2026, the 10-year Treasury yield sits at 4.56% while the national 30-year fixed mortgage rate averages 6.51%. The resulting spread of 1.95 percentage points (195 basis points) is only marginally narrower than the 2.00% level observed earlier in the year. This metric, often tracked as the “10 year treasury mortgage rate spread,” continues to signal elevated lender margins relative to the risk-free benchmark.
The spread has fluctuated within a tight band since the start of 2026. Data compiled from FRED show the 30-year mortgage rate averaged 6.51% against the 4.56% 10-year Treasury yield for the most recent reading. Earlier in January the spread reached 209 basis points before compressing to 201 basis points by the week ending January 9. By March, geopolitical tensions and energy-price spikes drove mortgage rates higher by 11 basis points in a single week, pushing the spread back toward the upper end of its recent range.
Mortgage pricing is anchored to the 10-year Treasury but includes additional costs for credit risk, servicing, and liquidity. When the spread widens, borrowers pay more than Treasury movements alone would suggest. Conversely, compression can offset modest Treasury increases. The current 1.95% spread indicates lenders are still embedding a sizable buffer above the 4.56% benchmark.

While national averages dominate headlines, local mortgage pricing can diverge. Redfin data shows spreads in high-cost coastal metros such as San Francisco and New York remain 5–12 basis points wider than the national figure, reflecting higher average loan sizes and servicing costs. In contrast, markets in Texas and Florida have seen spreads compress slightly below the 1.95% benchmark as competition among lenders intensifies.
Three primary factors sustain the current spread level:
These elements combine to keep the 10 year treasury mortgage rate spread from returning to the sub-150-basis-point levels common before 2022.
Absent a sharp decline in Treasury yields or a meaningful reduction in lender operating costs, the spread is likely to remain between 180 and 210 basis points through the remainder of 2026.
