Calculated from the weekly Thursday publication cadence and the latest stored observation (week ending 2026-10-15). Expected date, not a Freddie Mac commitment.
PMMS is a weekly benchmark published each Thursday — it measures the prior week and is not a daily rate series. For daily movement, use the OBMMI indices above. For mortgage benchmarks, a negative change (green) means rates improved.
30-Year PMMS — stored history
Mortgage spread: 30Y PMMS − 10Y Treasury
Mortgage spread
WEEKLY DERIVED2.30 pp
PMMS 30-Year minus 10-Year Treasury, anchored to the 2026-10-15 weekly PMMS observation date. Vabasso never pairs a stale PMMS reading with a newer Treasury observation to manufacture a daily spread.
Why mortgage spreads matter
Mortgage rates price off mortgage-backed securities, which trade at a spread over Treasury yields. When the spread between the 30-year mortgage benchmark and the 10-year Treasury widens, rates can rise even while Treasuries are flat — and when it narrows, borrowers benefit beyond what Treasury movement alone would suggest. Historical spread context computes automatically from stored weekly PMMS and daily Treasury observations.
Mortgage rate summary
Freddie Mac's national 30-Year Primary Mortgage Market Survey benchmark was 7.40% for the week ending Oct. 15, 2026. That is unchanged than the prior weekly reading of 7.40%. PMMS is a weekly national survey benchmark, not a daily quote and not an APR — it describes the survey week it covers, not today's market.
The 30-year mortgage / 10-Year Treasury spread was 2.30 percentage points on the Oct. 15, 2026 PMMS observation date. Vabasso derives this spread weekly and anchors it to each PMMS observation date, so it is never a same-day mortgage quote. A widening spread means mortgage rates are rising faster than Treasury yields; a narrowing spread means mortgage borrowers are capturing more of a Treasury rally.
The next Freddie Mac PMMS publication is expected on Thursday, Oct. 22, 2026. PMMS releases weekly on Thursdays; this expected date is calculated from the weekly Thursday publication cadence and the latest stored observation, and is not a Freddie Mac commitment.
