Are Higher Rates Coming Back? The Mortgage Math Worth Running Now
Are Higher Rates Coming Back? The Mortgage Math Worth Running Now
Updated September 26, 2026. Every rate, price and limit below was read that day from Freddie Mac, the Federal Reserve Board, the US Treasury, FHFA, the Census Bureau, HUD or the CFPB, all linked at the end. Payment and interest figures are amortisation arithmetic done here on a stated loan, not quotes from any lender. No lender, broker or rate-comparison site is cited anywhere in this article.
Where the rate is this week, and the year it has had
Freddie Mac's Primary Mortgage Market Survey for the week of September 24, 2026 puts the 30-year fixed at 7.03% and the 15-year fixed at 6.42%. A year earlier the same survey read 6.30% and 5.49%.
So the answer to the question in the headline is that higher rates are not coming back. They came back, in the seven months between February and September of this year. On February 26, 2026 the survey printed 5.98% — the first reading below 6% in about three and a half years. Today's number is 105 basis points above that. For the longer frame: the survey's record low was 2.65% in the week of January 7, 2021, and its recent-cycle peak was 7.79% in the week of October 26, 2023. Today sits 76 basis points below that peak.
Three rates move together, and the gap between two of them is the part nobody watches
The Federal Reserve set the target range for the federal funds rate at 3.75% to 4.00% at its September 16, 2026 meeting, effective the following day. The 10-year Treasury constant maturity yield closed at 5.18% on September 24, 2026.
Mortgage rates track the 10-year Treasury, not the policy rate, and the difference between the two is where lender costs and risk pricing live. Today that spread is 1.85 percentage points (7.03% minus 5.18%, calculated here). That number matters because it is the part of your rate that can move without the Fed doing anything at all — and the part that cannot be predicted from watching FOMC coverage.
On the policy side, the Summary of Economic Projections published with that September decision has the median participant putting the federal funds rate at 4.1% at the end of 2026 and 4.1% at the end of 2027, easing to 3.9% by the end of 2028, against a longer-run median of 3.2%. Read that carefully: 4.1% for end-2026 is above the midpoint of the range just set. The median projection is not for cuts next year. It is for the policy rate to sit slightly higher than today and stay there through 2027, with the same table showing median PCE inflation at 3.7% for 2026 and 2.3% for 2027, unemployment at 4.1% in both years, and real GDP growth of 2.3% and 2.4%.
Running the rates against one real price
The Census Bureau and HUD report the median sales price of new houses sold at $393,700 in August 2026, with an average of $478,700 and a seasonally adjusted annual sales rate of 684,000, released September 24, 2026. Take that median, put 20% down, and the loan is $314,960. Everything below is straight amortisation on that loan, principal and interest only — no taxes, insurance or HOA.
| Rate and term | Monthly P&I | Interest, first 5 yrs | Interest, first 10 yrs | Balance after 10 yrs |
|---|---|---|---|---|
| 30-year at 7.03% — this week | $2,102 | $107,719 | $207,719 | $270,465 |
| 30-year at 6.30% — one year ago | $1,950 | $96,161 | $184,640 | $265,658 |
| 30-year at 5.98% — this year's low, Feb 26 | $1,884 | $91,109 | $174,591 | $263,436 |
| 15-year at 6.42% — this week | $2,730 | $90,102 | $152,401 | $139,784 |
| 30-year at 7.79% — Oct 2023 peak | $2,265 | $119,794 | $231,943 | $275,088 |
| 30-year at 2.65% — Jan 2021 record low | $1,269 | $39,391 | $73,580 | $236,239 |
Three readings fall out of that table.
The seven months from February cost $217 a month. Same house, same down payment: 5.98% versus 7.03% is $13,049 over five years and $26,099 over ten. That is the price of the move that already happened, and it is the benchmark any "wait for rates to fall" argument has to beat.
The 15-year is not the expensive option it looks like. It costs $628 more a month than the 30-year at today's rates and saves $55,318 of interest over the first ten years, ending that decade with a balance of $139,784 instead of $270,465 — a difference in equity of $130,681 on the same house. Whether that is affordable is a cash-flow question; whether it is cheaper is not in dispute.
The 2021 row is there as a warning, not a target. At 2.65% this loan cost $1,269 a month. Nothing in the Fed's own projections points back toward that, and household budgeting built on its return is budgeting on a rate the survey printed once in fifty-five years of records.
What one discount point buys at this price
The CFPB's most recent published analysis of discount points, covering 2023, found 58.7% of purchase borrowers paid them, with a median of 1.0 point; among refinances, 56.2% on non-cash-out and nearly nine in ten on cash-out, at medians of 1.1 and 2.1 points. By loan type, roughly 65% of FHA borrowers and 62% of VA borrowers paid points on purchases. No more recent CFPB report on points could be found, so treat those shares as 2023 behaviour rather than today's.
On the $314,960 loan above, one point costs $3,150. A quarter-point rate reduction — 7.03% to 6.78% — lowers the payment by about $52.68 a month, which returns the $3,150 in roughly 60 months, or five years. That is the whole calculation, and it turns the decision into a single question: will this loan still be in place in five years? For a household likely to move or refinance sooner, buying points at this price and this rate is a loss.
Tip: Every number in the table above is four keystrokes on a machine that does not need a browser tab or a login. A financial calculator lets you re-run a payment and a break-even at the closing table, which is exactly where the pressure to accept a number without checking it is highest.

The 57% problem behind the whole market
An FHFA working paper on the lock-in effect found that as of the second quarter of 2024, 57% of fixed-rate mortgage borrowers held a rate below 4%. That figure is two years old and FHFA has not published a current update that could be located, so it should be read as dated context rather than today's share.
Even dated, it explains the market a buyer is walking into. A majority of existing owners are holding a mortgage that costs roughly $800 a month less than today's on a comparable balance, and selling means giving that up. That is why supply stays tight and why FHFA's House Price Index still shows prices rising: +2.1% year over year in the second quarter of 2026, +0.3% on the quarter, released August 25, 2026. Rates went up 105 basis points since February and prices did not fall.
The ceilings, in case the number is bigger than the median
For 2026 the FHFA baseline conforming loan limit for a one-unit property is $832,750, up $26,250 from 2025, with a high-cost area ceiling of $1,249,125 and a special ceiling of $1,873,675 for Alaska, Hawaii, Guam and the US Virgin Islands. HUD's FHA limits for one-unit properties run from a floor of $541,287 to a ceiling of $1,249,125.
These matter at the margin of a price negotiation: a loan a dollar over the conforming limit is priced as a jumbo, which is a different product with different underwriting, so the limit is worth knowing before agreeing a purchase price rather than after.
What the comparison actually decides
Set the two halves side by side. The measured cost of waiting from February to September was $217 a month on the median new house. The Fed's own median projection says the policy rate ends both 2026 and 2027 at 4.1%, marginally above where it sits now. The mortgage-to-Treasury spread is 1.85 points, wide enough that it could narrow and deliver relief without any policy change — but nothing published says when.
On those numbers the defensible position is that timing the rate is not the lever. The levers that are measurable today are the term (a 15-year is $628 more a month and $130,681 more equity in ten years), the points decision (a five-year break-even at this price), and the price itself, where FHFA says the market is still rising at 2.1% a year and Census says the median new house is $393,700. Two of those three are decided at the kitchen table, not by the FOMC.
The counter-case deserves stating: if the spread does narrow toward its historical norm while the policy rate holds, a refinance window could open without any Fed cut, and paying points today would then have been the wrong call. That is exactly why the break-even number above — sixty months — is the one to write down.
Five things to run before signing anything
- Amortise your actual loan amount at your actual quoted rate. The table above uses $314,960; your number changes every figure in it.
- Divide the cost of the points offered by the monthly saving they buy. If the answer is more months than you expect to keep the loan, decline them.
- Price the 15-year even if you intend to take the 30-year, so the equity difference is a choice rather than a default.
- Check your loan amount against $832,750 before agreeing a purchase price.
- Compare the mortgage rate you are quoted against the 10-year Treasury on the day. A spread far above 1.85 points is a question worth asking out loud.
