NEW YORK, NY — Mortgage rates are still climbing as 2026 heads toward its final quarter, but the longer-term picture points to gradual moderation rather than a dramatic drop. A five-year outlook on home loan costs suggests borrowers should not expect a return to the 3% rates that briefly appeared during the pandemic era.
The forecast ties mortgage pricing to Treasury yields, inflation trends and the Federal Reserve’s next moves. It also assumes the gap between bond yields and mortgage rates stays wider than it was in the 2010 to 2020 period, when that spread was usually smaller.
Why the 10-year Treasury matters so much for mortgage pricing
One of the clearest clues for where mortgage rates may go is the 10-year U.S. Treasury note. Mortgage rates and Treasury yields usually move in the same direction, though mortgage rates run higher because lenders build in extra risk. That difference is called the spread.
In recent years, that spread has often sat above 2.5 percentage points. By comparison, between 2010 and 2020 it was often under 2 points and sometimes near 1.5 points. A wider spread means home loans can stay expensive even when bond yields ease a bit.
The current market gives that point some context. On September 9, the 10-year Treasury yield was 4.88%, while the 30-year fixed mortgage rate stood at 6.76%, leaving a spread of 1.88 percentage points. That relationship is one reason mortgage rates do not simply mirror bond yields one for one.
Economists expect inflation to ease, but not in a straight line
Deloitte economist Michael Wolf said stronger inflation and solid payroll growth could push the Federal Reserve to raise interest rates by the end of this year. He added that the higher-rate environment may not last long and that the Fed could begin cutting rates before the end of 2027.
Wolf also pointed to lower oil prices next year as one reason inflation could cool sequentially. That matters because inflation has a direct effect on long-term interest rates and the borrowing costs tied to them. The five-year forecast uses those broad expectations as a starting point.
Other projections run somewhat higher over the long term. Goldman Sachs analysts see the 10-year Treasury rising to 4.5% by 2035, while the Congressional Budget Office expects the yield to reach 4.1% by the end of 2026 and about 4.3% by 2030.
A base-case path points to mortgage rates around 6.20% in 2027
Using those Treasury expectations and a mortgage spread that slowly narrows, the forecast builds a base case for the next five years. In that scenario, the spread starts at 2.00 percentage points in 2027 and gradually declines to 1.90 points by 2031.
Under that setup, mortgage rates edge lower over time instead of dropping sharply. The analysis says 2027 mortgage rates would be near 6.20%, a level that still leaves borrowing costs elevated by historical standards.
The approach also assumes the gap between mortgage rates and Treasury yields remains relatively sticky. The forecast says a Fannie Mae and Freddie Mac mortgage-backed securities buyback program launched on January 8, 2026, has kept the spread from widening further, though it has not meaningfully narrowed it.
Best-case and worst-case scenarios leave plenty of room for surprises
The outlook also includes two alternate paths. In the bull case, inflation returns to 2% without a severe recession, the Fed resumes cuts through 2027 and 2028, and the 10-year yield falls toward 3.30%. In that version, the 30-year mortgage rate could decline to about 5.05% by 2031.
The bear case looks very different. If inflation stays above 2.5%, deficits widen and foreign holders reduce their Treasury exposure, the 10-year yield could rise above 5%. Under those conditions, the mortgage spread could widen to 2.40 points and the 30-year rate could move above 7% in 2027 and 2028 before easing only slightly to 6.90% by 2031.
Those ranges show how sensitive mortgage pricing is to broader market shifts. Even small changes in bond yields or investor demand can alter what households pay on a monthly basis.
Why 3% mortgage rates are not part of the forecast
The forecast does not see 3% mortgage rates returning within the next five years. That kind of move usually requires a severe economic shock, such as a recession or a global crisis on the scale of the Great Recession or the pandemic.
The analysis also notes that rates were around today’s levels in 2007, before the financial crisis and the pandemic changed the borrowing environment. Those events are reminders that mortgage markets can move far more sharply than normal forecasts assume.
For households weighing a purchase or refinance, the practical message is less about waiting for a perfect rate and more about understanding the likely range. The forecast suggests moderation is possible, but a return to the old lows is not part of the base case.
What borrowers should watch as the next few years unfold
The biggest variables remain the same: Treasury yields, inflation, Federal Reserve policy and the mortgage spread. Any of those could move in a way that pushes borrowing costs lower or higher than expected. A recession could pull rates down quickly, while deficits, geopolitical stress or stronger inflation could keep them elevated.
That is why the forecast is best read as a guide rather than a promise. Borrowers considering a fixed-rate mortgage or an adjustable-rate loan still need to match the term to how long they expect to stay in the home and how much monthly payment they can handle.
For now, the broad expectation is gradual easing rather than a dramatic reset. Mortgage rates may moderate over the next five years, but the path is likely to remain uneven and highly dependent on the broader economy.
