Mortgage rates: Week of September 21, 2026
A plain, factual recap of where U.S. mortgage-rate benchmarks moved during Sep 21–24, 2026 — the OBMMI medians RallyRates tracks and the 10-year Treasury that anchors them. We report the moves; we never forecast.
| Benchmark | Mon | Fri | Week |
|---|---|---|---|
| 30-yr conventional | 7.034% | 7.244% | +21 bp |
| 15-yr conventional | 6.536% | 6.524% | −1 bp |
| FHA 30-yr | 6.802% | 6.952% | +15 bp |
| VA 30-yr | 6.752% | 6.929% | +18 bp |
| 10-yr Treasury (the driver) | 4.960% | 5.180% | +22 bp |
Over Sep 21–24, 2026, the conventional 30-year benchmark opened at 7.034% and closed at 7.244%. The 10-year Treasury climbed 22bp on the week, and conventional 30-year mortgage rates followed higher.
The 15-year conventional closed the week at 6.524%; FHA 30-year at 6.952%. These are benchmark medians, not a lender quote — for a live, lowest-APR-first board of real published rates, open the terminal.
On the calendar that week: 7-Year Treasury auction (Note) (Thu) — the scheduled releases that most move the Treasury market behind mortgage rates. We note what was on the docket, not a cause.
