Latest 10 year treasury mortgage rate spread reading shows 30-year fixed at 6.43% and 10-year Treasury at 4.48% for a 1.95% gap as of July 2026.
As of the July 2, 2026 FRED release, the 30-year fixed mortgage rate stood at 6.43% while the 10-year Treasury yield printed 4.48%, producing a 1.95 percentage-point spread. This marks a modest contraction from the 1.99% gap observed in late May, suggesting early signs that the historically wide mortgage-to-Treasury differential may be stabilizing.
The 10-year Treasury serves as the primary benchmark for long-term borrowing costs. Lenders price 30-year mortgages off this yield plus a spread that compensates for credit, prepayment, and liquidity risk. Because the 10-year note is highly liquid and actively traded, even small daily moves transmit quickly into mortgage pricing sheets.
Several structural factors keep the spread elevated. First, interest-rate volatility—captured by the MOVE index—remains above pre-pandemic averages, forcing originators to build larger cushions. Second, the ongoing runoff of the Federal Reserve’s MBS portfolio (QT) has reduced demand for mortgage-backed securities relative to Treasuries, widening required yields. Third, bank balance-sheet constraints and regulatory capital rules continue to limit appetite for holding whole loans, adding another layer of cost.
| Date Range | 30Y Fixed | 10Y Treasury | Spread |
|---|---|---|---|
| July 2023 | 6.81% | 3.88% | 2.93% |
| July 2024 | 6.95% | 4.25% | 2.70% |
| May 2026 | 6.47% | 4.48% | 1.99% |
| July 2, 2026 | 6.43% | 4.48% | 1.95% |
The table illustrates that spreads peaked above 290 basis points in 2023 before compressing roughly 100 basis points as volatility subsided and MBS supply dynamics improved.
While the national 30-year average is 6.43%, state-level data show modest dispersion. Texas and Florida posted averages of 6.38% and 6.41% respectively, while California and New York printed 6.51% and 6.49%. These differences largely reflect varying average credit scores and loan-to-value distributions rather than local Treasury yields, which remain uniform nationwide.
Forward curves priced in futures markets imply the 10-year Treasury will trade in a 4.35–4.60% band through year-end. If realized volatility declines another 10–15%, mortgage spreads could compress toward 1.80–1.90% by December. Conversely, any renewed inflation spike or fiscal-supply surge could push the 10-year yield above 4.70% and keep spreads near current levels.
Borrowers evaluating rate-lock decisions should monitor the daily 10-year Treasury print alongside the MBA’s weekly mortgage-rate survey. Small changes in the benchmark can translate into 5–10 basis-point moves in offered mortgage rates within 24–48 hours.

The latest 10 year treasury mortgage rate spread reading of 1.95% remains wider than the long-term average of roughly 1.60%, yet shows early compression. Absent a sharp rise in Treasury volatility or renewed MBS supply pressure, the spread is likely to settle between 1.80% and 2.00% for the balance of 2026, keeping 30-year fixed rates in the mid-6% range even if the 10-year yield holds near 4.5%.
