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. A new 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: 6.87% 30-year fixed (+0.06 on the day) — Mortgage News Daily, as of August 31, 2026. The same index shows the 15-year at 6.38%, FHA 30-year at 6.40%, VA 30-year at 6.42%, jumbo 30-year at 6.92% and the 7/6 ARM at 6.42%.
10-year Treasury: just under 4.74% at Monday’s close, per Mortgage News Daily’s market commentary.

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

What moved rates

Monday extended Friday’s move. The Mortgage News Daily 30-year index added another six basis points to 6.87% — which the index publisher describes as its highest reading in over a year, though only marginally above the prior highs. Unlike Friday, when a hawkish Jackson Hole speech did the damage, Monday’s driver was mostly mechanical: month-end trading, when large funds adjust positions on the calendar rather than on news. Bonds opened slightly stronger and then sold off just after 8am, and the 10-year Treasury yield finished just under 4.74%.

The gap between the two headline numbers on this page is now the widest it has been since this site launched: the weekly survey still reads 6.66%, collected before both Friday’s and Monday’s moves, while the daily index sits 21 basis points higher. Thursday’s new survey will close much of that gap unless markets reverse first.

The data that could move things starts today: job openings (JOLTS) arrives at 10am Eastern, a second-tier release that matters more than usual right now because the Fed has said the labor market is central to its next decision. The fresh Freddie Mac survey lands Thursday at noon, and Friday morning brings the August jobs report — the release with the strongest track record of moving mortgage rates in either direction. The bond market is closed next Monday for Labor Day, and the next FOMC meeting is September 15–16.

What it means if you are…

Buying. Budget off the daily index this week, not the weekly survey — 6.87% is closer to what rate sheets showed Monday than 6.66% is. Two rough days do not change what home you can afford, but they do change the payment math at the margin; the calculators on this site update the numbers in seconds.

Refinancing. The last three trading days have moved away from refinancers. That is exactly when the break-even math is worth having ready rather than needing: this week’s data — especially Friday’s jobs report — gives the market several chances to swing back, and a soft report has historically been the kind of print that pulls rates down quickly. The refinance savings check on this site takes a few minutes.

Under contract. With rates at the top of their recent range and a jobs report Friday, this is a week to make the lock decision deliberately rather than by default. The honest framing: locking here protects against the report coming in strong; floating leaves room to benefit if it comes in weak. Which side of that trade fits you depends on your closing date and how much payment risk your budget can absorb — not on anyone’s forecast.

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 6.87%, the same loan is approximately $2,626 — a difference of about $56 a month, or roughly $20,000 across the full term. That is what three weeks of drift looks like in dollars. 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 1 is the first day of the month many Florida insurance policies renew, and a renewal premium that jumped matters to a mortgage in a specific way: if your escrow account pays the new, higher premium, your servicer will recalculate the escrow portion of your payment at the next analysis — sometimes months later, and sometimes with a shortage to catch up. If you own and your insurance renewed higher this fall, expect the escrow adjustment letter and budget for it early. If you are buying, ask for the actual current-year premium on the home, not last year’s figure, before you finalize your monthly budget.
