Nothing moved. Bankrate's 30-year printed 6.69% Friday, Saturday, and again today — three sessions flat, no print, no catalyst, and a weekend tape with nothing to trade against. The one thing that did move happened earlier in the week and hasn't transmitted: the 10-year fell to 4.63% Thursday from 4.70% Tuesday, seven basis points the mortgage side simply didn't take. Freddie's survey picked up two of them at 6.67%. If you need a reason to explain the flatness to a client, there isn't one beyond the calendar — August Sundays don't produce catalysts.
Housing starts and permits land Tuesday; jobless claims and Freddie's weekly survey both print Thursday. That is the week. Claims are drifting up at 209,000 against 200,000 prior, and permits already came in soft at 1.374 million versus 1.410 million. A second soft housing read Tuesday plus a claims number that keeps climbing Thursday would give the bond move follow-through and finally drag the retail 30-year with it; a hot starts number does the opposite. The next FOMC meeting is September 15–16 and it carries a Summary of Economic Projections, so the dot plot is live — but nothing on this week's calendar forces anything before then.
Today's 6.69% sits almost exactly mid-range: 3 bps under the 30-day average of 6.726% and 6 bps over the 90-day average of 6.632%, inside a 90-day band of 6.47% to 6.82%. There is nothing left to say about the 30-year that the last two pulses haven't already said, so look up the curve instead. The 15-year is at 6.07% — 62 bps under the 30-year and only 5 bps above its own 90-day average. Jumbo at 6.85% is just 16 bps over conforming, a spread tight enough that a $900K borrower is barely paying anything for the size of the loan. Those two spreads are where the pricing is actually interesting this week. The headline number is not.
The segment today is the borrower with real cash flow who defaulted to a 30-year because that is what everyone quotes. On $400K, the 30-year at 6.69% runs about $2,578 a month; the 15-year at 6.07% runs about $3,390 — $812 more each month, but roughly $318,000 less interest over the life of the loan. That is not a fit for most files and you should not pitch it broadly. It is a fit for the move-up buyer sitting on equity, the business owner with lumpy but large income, and the refi candidate already ten years into a 30-year who restarts the clock every time you quote them. Do this today: pull your last 20 quotes, flag every file with a debt-to-income under 30%, and send those borrowers a two-line 15-year comparison next to the number you originally gave them.
