The average rate on a 30-year fixed mortgage jumped a quarter of a percentage point this week to 7.28%, the highest reading in nearly three years and the largest one-week increase since the fall of 2022, as a sustained selloff in the Treasury market pushed long-term borrowing costs higher.
Freddie Mac’s Primary Mortgage Market Survey, released Oct. 1, 2026, put the 30-year fixed-rate average at 7.28%, up from 7.03% a week earlier. A year ago the same average was 6.34%. The 15-year fixed-rate mortgage averaged 6.60%, up from 6.42% last week and 5.55% a year ago.
The 25-basis-point weekly move is unusually large for a survey that normally shifts a few hundredths of a point at a time. According to Freddie Mac’s own weekly series, which runs back to April 1971, the last time the 30-year average rose that much or more in a single week was the week of Oct. 13, 2022, when it climbed 26 basis points during that year’s inflation shock.
The level is also the highest since the week of Nov. 22, 2023, when the 30-year average stood at 7.29% β during the last stretch in which the survey ran above 7%.
What is driving mortgage rates higher
The move follows weeks of rising government bond yields, which mortgage rates track closely. The 10-year Treasury note yielded 5.29% at the close on Sept. 30, according to the U.S. Treasury Department’s daily yield curve, up from 4.96% on Sept. 22 and 4.79% on Sept. 1. The 30-year Treasury bond finished Sept. 30 at 5.64%.
The Federal Reserve has been moving in the same direction. At its Sept. 15-16 meeting the Federal Open Market Committee raised the federal funds target range by a quarter point, to 3.75% to 4%, in a unanimous 12-0 vote, saying inflation “remains elevated” and that the increase would “support a timelier return to the Committee’s 2 percent goal.” That was the central bank’s first increase since 2023.
Freddie Mac itself offered a restrained read on the market in its weekly commentary, saying that “with mortgage rates on their current trajectory, the housing market continues to be supported by favorable economic conditions.”
One timing detail matters for anyone trying to anticipate next week. PMMS results are an average of loan rates offered from the prior Thursday through Wednesday β in this case Sept. 24 through Sept. 30. The survey therefore captures last week’s bond move, not Thursday’s trading. If yields hold at current levels, the pressure in this week’s figure is unlikely to reverse in the next one.
The cost to borrowers
On a $400,000 30-year loan, principal and interest at 7.28% work out to roughly $2,737 a month, compared with about $2,669 at last week’s 7.03% β an increase of about $68 a month from a single week’s move. Against the 6.34% average of a year ago, the same loan costs about $251 more each month, or roughly $3,000 a year.
Borrower behavior has already shifted. Lender survey data released Sept. 30 showed the average contract rate on 30-year conforming applications at 7.30% and total application volume down 6% for the week, as reported in RealtyWire’s coverage of the latest Mortgage Bankers Association survey. Adjustable-rate products have been drawing a growing share of applicants through the climb, a pattern visible since the 30-year average crossed 7.12% earlier in this cycle.
The 30-year average has now risen 52 basis points in three weeks, from 6.76% on Sept. 10. For much of 2026 the survey moved in a narrow band in the mid-6% range; it has broken out of that range decisively in September.
Where this leaves the fall market
Rates at this level reshape the arithmetic of the autumn selling season. Sellers who listed in the summer priced into a mid-6% market; buyers shopping in October face payments a quarter point higher than they did a week ago and nearly a full point higher than a year ago. The gap between what sellers list and what buyers can finance widens with every basis point, and on our reading the adjustment is more likely to show up in asking prices than in volume, because a seller can cut a price and a buyer cannot cut a rate.
For lenders, the immediate consequence is a refinance pipeline with very little left in it β borrowers who closed in the mid-6% range have no reason to move β and a purchase market in which rate locks are harder to hold through a closing. For the Fed, the move illustrates a point policymakers have made repeatedly: long rates are set in the bond market, and a central bank fighting inflation does not control them directly.
Freddie Mac publishes the next PMMS reading on Thursday, Oct. 8, at noon Eastern. More mortgage market coverage is collected on RealtyWire’s mortgage page.
