Fed rate decision mortgage rates outlook: 30-year fixed at 6.76% and 15-year at 6.09% as the FOMC meets September 15, 2026 with the funds rate at 3.5-3.75%.
As of September 10, 2026, the 30-year fixed mortgage rate stands at 6.76% and the 15-year fixed at 6.09%, according to FRED data. The 10-year Treasury yield is 4.96%, producing a 1.8-percentage-point spread between the benchmark note and the 30-year mortgage. These levels reflect the market’s pricing of the federal funds rate target range of 3.5%–3.75% that has remained unchanged since the January 2026 FOMC meeting.
The FOMC is scheduled to conclude its September 15–16, 2026 meeting at 2:00 p.m. ET. Futures markets assign a greater-than-80% probability that the Committee will leave the federal funds rate unchanged for a fourth consecutive meeting. Minutes from the July 29–30 session noted that “future hikes may be a possibility” if inflation re-accelerates, but no voting member dissented from the hold decision. The September dot plot is expected to show only modest shifts in the median 2027 projection, keeping the policy rate near current levels through year-end.
Mortgage pricing is anchored to the 10-year Treasury yield rather than the federal funds rate directly. Since January, the 10-year note has traded in a 60-basis-point band, limiting volatility in primary mortgage rates. The current 1.8-percentage-point spread is 12 basis points wider than the 2025 average, reflecting elevated servicing costs and hedging expenses passed on by lenders. Should the FOMC signal a December hike, the 10-year yield could rise 15–25 basis points intraday, translating to roughly a 10–15 basis point increase in 30-year mortgage quotes within 48 hours.
Rate sheets released September 10 show modest geographic dispersion. In the Atlanta metro, conforming 30-year fixed loans averaged 6.71%, while San Francisco averaged 6.84%. Dallas posted 6.73% and Chicago 6.79%. These differences stem primarily from average credit scores and property tax structures rather than Fed policy expectations.
| Date | Fed Funds Range | 30Y Fixed | 10Y Treasury | Spread |
|---|---|---|---|---|
| Jan 28, 2026 | 3.50–3.75% | 6.55% | 4.71% | 1.84% |
| Apr 29, 2026 | 3.50–3.75% | 6.61% | 4.78% | 1.83% |
| Jul 29, 2026 | 3.50–3.75% | 6.70% | 4.88% | 1.82% |
| Sep 10, 2026 | 3.50–3.75% | 6.76% | 4.96% | 1.80% |
The table illustrates that mortgage rates have risen 21 basis points since the last rate decision, driven by the Treasury yield climb rather than any change in the federal funds target.
A “no-change” statement on September 15 would likely keep the 30-year fixed mortgage rate within a 6.70%–6.85% corridor through October. Conversely, if the Summary of Economic Projections reveals two projected hikes by mid-2027, the 10-year yield could test 5.15%, pushing 30-year quotes above 7.00% for the first time since December 2025.

With the federal funds rate steady at 3.5%–3.75% and the next policy move uncertain, the September 15 decision is unlikely to trigger an immediate repricing in mortgage rates. However, any hawkish tilt in the dot plot could lift 30-year fixed rates toward 7.00% by year-end. Homebuyers and refinancers should monitor the post-meeting press conference closely and lock rates if their break-even horizon is less than 36 months.
