Fed rate decision mortgage rates outlook for August 2026: 30-year fixed at 6.65% and 15-year at 5.95% as the FOMC holds policy steady.
As of August 20, 2026, the 30-year fixed mortgage rate stands at 6.65% and the 15-year fixed at 5.95%, according to FRED data. The 10-year Treasury yield is 4.7%, producing a mortgage spread of 1.95 percentage points. These levels have remained largely unchanged since the Federal Open Market Committee’s July 29 decision to leave the federal funds rate in the 3.50%–3.75% range.
The FOMC’s next policy statement arrives on August 26, 2026. CME Group’s FedWatch tool currently assigns a 35% probability to a rate hike at this meeting—the first time in several years that possibility has been priced at more than negligible odds. A hike would push the upper bound of the target range to 4.00%, while a hold would leave the range unchanged.
Mortgage pricing is influenced more directly by the 10-year Treasury yield than by the federal funds rate. Nevertheless, any shift in the policy path can move Treasury yields and, in turn, mortgage rates. The current 1.95-point spread between the 10-year Treasury and the 30-year fixed mortgage is near the upper end of its five-year range, indicating that lenders are embedding a sizable risk premium.
The March 2026 FOMC statement also left rates unchanged at 3.50%–3.75%, signaling that the Committee viewed inflation and employment data as balanced. Since that meeting, the 30-year fixed mortgage rate has fluctuated between 6.50% and 6.80%, per FRED weekly averages. The stability in the federal funds rate has not translated into lower mortgage rates because Treasury yields have remained elevated on persistent inflation readings.
Rate sheets issued the week of August 20 show modest geographic dispersion. In Seattle and Denver, average 30-year fixed quotes sit 4 basis points below the national 6.65% figure, while Atlanta and Phoenix quotes are 3–5 basis points higher. These differences stem primarily from average credit scores and loan-size distributions rather than from any regional Fed policy.
| Scenario (Aug 26) | Fed Funds Upper Bound | Implied 10Y Yield | 30Y Mortgage (est.) |
|---|---|---|---|
| Hold | 3.75% | 4.65–4.75% | 6.55–6.70% |
| 25 bp Hike | 4.00% | 4.85–4.95% | 6.80–6.95% |
The table above illustrates the two most likely outcomes priced by futures markets. A hold would likely keep the 30-year fixed mortgage rate within a 6.55%–6.70% band, while a hike could push quotes above 6.80%.

Unless the August 26 statement signals a clear shift toward higher rates, the 30-year fixed mortgage rate is likely to remain near 6.65%. A 25-basis-point hike would add roughly $50 per month on a $400,000 loan; a hold would leave payments effectively unchanged.
