The 10 year treasury mortgage rate spread stood at 1.99% on June 4, 2026, with the 30-year fixed at 6.48% and the 10-year Treasury at 4.49%.
As of the June 4, 2026 FRED reading, the 30-year fixed mortgage rate was 6.48% while the 10-year Treasury yield sat at 4.49%, producing a 10 year treasury mortgage rate spread of 1.99 percentage points. This level remains near the upper end of the range observed since early 2023 and well above the long-term average of roughly 1.6–1.8 points.
The 10 year treasury mortgage rate spread measures the additional compensation investors demand to hold mortgage-backed securities instead of risk-free Treasuries. A wider spread raises borrowing costs for households even when Treasury yields are stable or falling. In 2026 the spread has averaged close to 200 basis points, reflecting elevated interest-rate volatility and thinner secondary-market liquidity.
Data from YCharts show the spread averaged 1.65 points between 2015 and 2019. During the 2020–2021 refinancing wave it briefly compressed below 1.4 points before widening sharply in 2022. The current 1.99-point gap is the second-widest reading since October 2021, surpassed only by the March 2023 peak of 2.12 points.
Three primary factors keep the spread elevated:

Forward-looking indicators suggest limited near-term compression. The Treasury yield curve has steepened, with the 10-year/30-year spread reaching 56 basis points—the widest since October 2021. Unless volatility declines or MBS demand rebounds, analysts expect the 10 year treasury mortgage rate spread to remain between 1.85 and 2.10 points through the third quarter.
