Mortgage rates: Week of August 17, 2026
A plain, factual recap of where U.S. mortgage-rate benchmarks moved during Aug 17–21, 2026 — the OBMMI medians RallyRates tracks and the 10-year Treasury that anchors them. We report the moves; we never forecast.

Over Aug 17–21, 2026, the conventional 30-year benchmark opened at 6.669% and closed at 6.698%. The 10-year Treasury climbed 2bp on the week, and conventional 30-year mortgage rates followed higher.
The 15-year conventional closed the week at 5.948%; FHA 30-year at 6.474%. 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: Retail sales (Thu) — the scheduled releases that most move the Treasury market behind mortgage rates. We note what was on the docket, not a cause.
