The 30-year fixed mortgage rate rose 5 basis points to 6.76% this week, while its spread over the 10-year Treasury yield widened 2 basis points to 1.93 percentage points.

On Sept. 3, 2026 — within the observation window that precedes this week's Treasury and mortgage readings — Federal Reserve Governor Christopher Waller gave a speech on the economic outlook in which he put annual PCE inflation at 3.7% and core PCE at 3.3%, both above the Fed's 2% goal, and said "if this continues in the data due over the next two weeks, I would be inclined to support holding the target for the federal funds rate at its current setting," while saying it may be appropriate to raise the policy rate at the Fed's Sept. 15-16 meeting if that improvement proves fleeting. Separately, expanded U.S. Treasury buyback operations aimed at long-end liquidity support took effect Sept. 9, 2026, the same date as this week's 10-year Treasury observation; Treasury had announced in August that it would at least double the size of those operations for the current refunding quarter, and it characterized the change as liquidity support rather than a policy-rate action.

Also within that same observation window, the Bureau of Labor Statistics released its Employment Situation report for August 2026 on Sept. 4, reporting a 162,000 increase in nonfarm payrolls, an unemployment rate holding at 4.1%, and upward revisions of 11,000 for June and 44,000 for July. (Data accessed from bls.gov on Sept. 10, 2026; BLS states it does not vouch for analyses performed with its data after retrieval.)

Freddie Mac's Primary Mortgage Market Survey, released Sept. 10, 2026, showed the average 30-year fixed mortgage rate at 6.76%, up 5 basis points from 6.71% in the week ended Sept. 3, and the average 15-year fixed rate at 6.09%, up 5 basis points from 6.04%. Federal Reserve H.15 data over the same span put the 10-year Treasury yield at 4.83% on Sept. 9 (up 3 basis points from 4.80% on Sept. 8) and the 2-year yield at 4.43% (up 4 basis points from 4.39%); those two Treasury readings reflect Sept. 9, one day earlier than this brief's Sept. 10 date, while the mortgage figures reflect Sept. 10 itself. The rate any individual borrower is actually offered depends on credit profile, loan term and lender.

This week's spread between the 30-year mortgage rate and the 10-year Treasury yield — a measure of how much mortgage pricing sits above the benchmark long-term government yield — widened by 2 basis points to 1.93 percentage points. Nothing in this session's sourcing speaks to that 2-basis-point move directly; it is simply the arithmetic difference between the mortgage and Treasury changes reported above, so it is carried here as an unconfirmed background item rather than an inferred cause. The spread between the 10-year and 2-year Treasury yields, a common gauge of the yield curve's slope, narrowed by 1 basis point to 0.40 percentage points over the same week, again with no official source addressing that move specifically.

What to watch next: Freddie Mac's next Primary Mortgage Market Survey is due Thursday, Sept. 17, 2026, and the Federal Reserve updates its H.15 Treasury yield series on the next business day.
