Freddie Mac's weekly survey showed both fixed mortgage rates edging higher: the 30-year average rose 1bp to 6.66% and the 15-year average rose 3bp to 5.98%, while background Treasury yields ticked up 2bp across both maturities.

Freddie Mac's Primary Mortgage Market Survey (PMMS) commentary for the week of Aug 27, 2026 quoted Chief Economist Sam Khater saying mortgage rates "changed little this week." Freddie Mac attributed the broadly stable rate environment to a resilient economy -- steady consumer spending and rising household incomes -- and to improving housing-market balance from more listings and slower price growth. Freddie Mac's release did not single out a specific driver for this week's 1bp and 3bp moves in the 30-year and 15-year averages, so no specific cause is asserted here beyond that general framing.

The 30-year fixed-rate mortgage average (MORTGAGE30US) rose 1 basis point, from 6.65% for the week ending Aug 20, 2026 to 6.66% for the week ending Aug 27, 2026 -- up from 6.56% a year earlier. The 15-year fixed-rate mortgage average (MORTGAGE15US) rose 3 basis points, from 5.95% to 5.98% over the same one-week period, up from 5.69% a year earlier. Both figures come from Freddie Mac's weekly PMMS; as with any published national average, the rate actually offered to an individual borrower varies by credit profile, loan term, and lender.

For background only -- this cycle's scope is mortgage-focused -- the 10-year Treasury yield (DGS10) rose 2 basis points, from 4.64% on Aug 25, 2026 to 4.66% on Aug 26, 2026, and the 2-year Treasury yield (DGS2) also rose 2 basis points, from 4.17% to 4.19% over the same period. The Bureau of Economic Analysis's July 2026 Personal Income and Outlays release, published the same day (Aug 26, 2026), reported the PCE price index up 3.7% year-over-year. Both events fell on the same date, but no confirmed source establishes a causal link between the PCE report and that day's yield moves, so none is claimed here.

Two spreads describe the observed relationship between series in this snapshot. The 30-year mortgage rate over the 10-year Treasury yield stood at 2.00 percentage points (200bp) -- pairing the weekly mortgage reading (Aug 27, 2026) with the daily Treasury reading (Aug 26, 2026), a one-day gap consistent with the two series' different observation cadences. The 10-year/2-year Treasury spread was 0.47 percentage points (47bp) as of Aug 26, 2026. These figures reflect only the snapshot date's observed values, not a trend.

What to watch next: Freddie Mac's next weekly PMMS reading, following the weekly cadence seen in this snapshot (Aug 20 to Aug 27), would fall on Sep 3, 2026. Daily Treasury yields (DGS10, DGS2) update with each new Federal Reserve H.15 business-day release.
