Today’s index numbers

30-year fixed: 6.66% (+0.01 vs. prior week) — Freddie Mac Primary Mortgage Market Survey, week of August 27, 2026. The next survey publishes Thursday, September 3.
15-year fixed: 5.98% (+0.03 vs. prior week) — Freddie Mac Primary Mortgage Market Survey, week of August 27, 2026
Daily rate index: 6.81% 30-year fixed (+0.06 on the day) — Mortgage News Daily, as of Friday, August 28, 2026. The same index put the 15-year fixed at 6.35% (+0.03).
10-year Treasury: about 4.71% as of Friday’s close, per Mortgage News Daily’s market commentary.

These are national survey and index averages, not an offer.

What moved rates

The Jackson Hole speech that Friday’s post flagged as the event of the day turned out to matter. Fed Chairman Kevin Warsh’s remarks were read by bond markets as hawkish — less friendly to near-term rate cuts than traders had positioned for — and the reaction was heavy selling in Treasuries and mortgage-backed securities. By Friday afternoon the Mortgage News Daily 30-year index had climbed six basis points to 6.81%, its highest reading in about three weeks, and the 10-year Treasury yield finished near 4.71%.

That leaves a gap worth understanding as the week opens: the weekly survey still reads 6.66%, but it was collected before Friday’s move. Unless markets reverse, Thursday’s new survey is likely to reflect some of the jump. The daily index is the closer picture of where rate sheets actually opened this morning.

The week ahead is a busy one. Job openings data (JOLTS) arrives Tuesday morning, the new Freddie Mac survey lands Thursday at noon, and Friday brings the August jobs report — the single release with the most consistent track record of moving mortgage rates in either direction. Markets are then closed next Monday for Labor Day. The next FOMC meeting, with updated economic projections, is September 15–16.

What it means if you are…

Buying. The reference points moved apart over the weekend: 6.66% on the weekly survey, 6.81% on the daily index. For budgeting this week, the daily index is the more current of the two. As always, compare actual offers against each other on the same day, using rate and APR together, rather than against either average.

Refinancing. Friday’s move ran in the unhelpful direction, but a six-basis-point swing can retrace just as quickly — and this week’s data gives it several chances to move either way. Knowing your break-even number before Friday’s jobs report means you can act on a favorable print instead of scrambling to calculate one. The refinance savings check on this site takes a few minutes.

Under contract. This is a scheduled-news week, with the jobs report Friday as the headline risk. A lock decision should follow your closing date and your tolerance for payment changes rather than a guess about the report — but if your closing is near and a payment jump would strain the budget, the days before a jobs report are historically when rate volatility clusters.

What a $400,000 loan looks like at today’s average

At 6.66% on a 30-year fixed, principal and interest on a $400,000 loan is approximately $2,571 per month (6.66% ÷ 12 = 0.555% monthly rate, over 360 payments). At the daily index reading of 6.81%, the same loan is approximately $2,610 — a difference of about $40 a month, or roughly $14,300 across the full term. These figures exclude property taxes, homeowners insurance, flood insurance, mortgage insurance and any association dues; the actual monthly obligation will be greater.

Florida note

September opens the statistical peak of hurricane season, and it matters for closings: when a named storm approaches Florida, insurance carriers stop binding new homeowners and flood policies until the threat passes. A closing cannot fund without insurance in place, so a storm in the forecast can delay a purchase by days or weeks through no fault of the buyer or lender. If you are under contract, binding your homeowners policy early — rather than the week of closing — removes that risk from your timeline entirely.
