No move today — Bankrate's conventional 30-year printed 7.12% for a second straight session. The week is the story, not the day: the same series carried 6.90% on the 13th, so twenty-two basis points went on the board in seven sessions, all of it after the FOMC raised its target range a quarter point to 3.75–4.00% on September 16 on a 12–0 vote. The 10-year Treasury followed through to 5.01% on the 18th from 4.94% the day before, the highest close in a series running since January 2025, while the 10-year/2-year spread narrowed to 0.25 from 0.27. Freddie's PMMS — a weekly average and a different survey — put the 30-year at 6.95% for the week ending September 17, up 19 basis points. Same direction, same magnitude.
The calendar does the work next week. August core PCE is due between September 23 and 30 and is the only print with the weight to reset the front of this move. Case-Shiller lands on the 22nd, initial claims and the next PMMS on the 24th, new home sales between the 23rd and 26th. The next FOMC is October 27–28 and carries no Summary of Economic Projections, so there is no dot plot to reprice against and that meeting trades off statement language alone. Between now and PCE there is no scheduled catalyst, which leaves the tape to positioning.
What is different about this week is worth saying plainly: there is nowhere in the product set that is not at its ceiling. The conventional 30-year at 7.12% is the top of its 6.47% to 7.12% range across 85 observations since June 22, against a 6.727% average. The 15-year at 6.49% sits at the top of its own 5.85% to 6.49% band over the same 85 sessions, and it added 25 basis points this week against the 30-year's 22. MND's 5/1 ARM, tracked on a separate survey, is at 6.75% at the top of a 6.21% to 6.75% range across 91 observations — but it added only 8 basis points on the week, so the adjustable product absorbed the least of this move. Inside the fixed set the 30-year to 15-year gap held at 63 basis points against 66 a week ago: the shape barely changed while the whole thing shifted up.
The segment that matters today is the borrower who took a quote in the last three weeks and has not locked. Floating has cost money in every window we can measure — the 30-year is 22 basis points above a week ago and 40 above the 6.72% it carried a month ago, which on a $400K loan is roughly $59 a month against last Sunday's quote. There is no scheduled event between now and core PCE that argues for waiting on purpose. Do this today: work your unlocked pipeline from the oldest quote forward, tell each borrower in dollars how far their number has moved, and get a lock decision on record before PCE prints next week.
