The average 30-year fixed mortgage rate rose to 7.12% in the week ending September 18, 2026, its highest level since May 2024, according to the Mortgage Bankers Association. Total mortgage applications fell 1.5%, and refinance activity dropped to its slowest pace since February 2025 as buyers and homeowners pulled back.
Key Takeaways

- The Refinance Index fell 3% for the week and was 62% lower than the same week in 2025.
- The adjustable-rate mortgage share of applications rose to 9.8%, as 5/1 ARM rates fell to 6.10%, more than a full point below fixed rates.
- Freddie Mac’s 30-year fixed average was 6.95% as of September 17, up from 6.26% a year earlier, with a new reading due September 24.
- August existing-home sales fell 2.0% to a 3.98 million annual rate, while inventory reached 1.62 million homes, a 4.9-month supply.
- The median existing-home price was $429,100 in August, up 1.6% from a year earlier and the 38th straight month of annual price gains.
The MBA Survey Shows Borrowers Pulling Back
The Mortgage Bankers Association’s Weekly Mortgage Applications Survey, released September 23, showed higher borrowing costs weighing on both purchase and refinance demand. The Market Composite Index, which measures overall application volume, fell 1.5% on a seasonally adjusted basis from the prior week.
The seasonally adjusted Purchase Index fell 1%, and the unadjusted Purchase Index was 11% below the same week a year earlier. Refinancing weakened more sharply. The Refinance Index fell 3% for the week and was 62% lower than a year ago. The refinance share of total applications slipped to 39.3% from 39.4%.
Mike Fratantoni, the MBA’s Senior Vice President and Chief Economist, said mortgage rates “vaulted higher last week,” and that the latest decline pushed refinancing to its slowest pace since February 2025. He also noted that the comparison week included the Labor Day holiday, which the MBA adjusts for in its seasonal figures.
Rates Rose Across Nearly Every Loan Type
The increase was not limited to conforming loans. The average contract rate on 30-year fixed conforming loans of $832,750 or less rose to 7.12% from 6.97%, with points edging up to 0.73. Jumbo loans above that limit averaged 7.15%, up from 7.03%.
Government-backed and shorter-term loans followed the same pattern. The average rate on 30-year FHA loans rose to 6.78% from 6.62%, and the 15-year fixed rate climbed to 6.43% from 6.30%. The only major product that got cheaper was the 5/1 adjustable-rate mortgage, which fell to 6.10% from 6.23%.
ARM Demand Rises as the Rate Gap Widens
The difference between fixed and adjustable rates is changing borrower behavior. Fratantoni said the ARM share reached 9.8% of applications, as 5/1 ARM rates ran more than a percentage point below fixed rates.
That gap is significant. As an illustration, a $400,000 loan at 7.12% carries a principal-and-interest payment of roughly $2,690 a month. At 6.10%, the same loan costs about $2,420, a difference of roughly $270 a month during the fixed-rate period. The trade-off is that an ARM resets after its initial term, so the lower payment is not guaranteed for the life of the loan.
The rise in ARM share is also a signal about affordability. When more borrowers are willing to take on rate-reset risk to qualify for a loan or lower a payment, fixed-rate financing is putting real pressure on budgets.
Freddie Mac Data Confirms the Upward Trend
Freddie Mac’s Primary Mortgage Market Survey, which uses a different method from the MBA, shows the same direction. The 30-year fixed-rate mortgage averaged 6.95% as of September 17, 2026, up from 6.76% a week earlier and 6.26% a year ago. The 15-year fixed averaged 6.26%, up from 5.41% a year earlier.
Using Freddie Mac’s figures, a borrower financing $400,000 at this year’s 6.95% pays roughly $180 more per month in principal and interest than at last year’s 6.26%. Over a full 30-year term, that adds up to about $65,000 in added interest. Freddie Mac’s next weekly reading is scheduled for Thursday, September 24.
Treasury Yields and Fed Policy Are Driving Rates Higher
Mortgage rates generally follow the 10-year Treasury yield, not the Federal Reserve’s short-term policy rate directly. The 10-year yield reached 5.135% on September 23, its highest level since July 2007, after hotter-than-expected business activity data increased concerns about inflation.
Monetary policy adds to the pressure. On September 16, the Federal Open Market Committee raised the federal funds target range by a quarter point to 3.75%–4.00%, its first increase since 2023, and said inflation remains elevated. The next FOMC decision is scheduled for October 28. Higher energy prices have also pushed up inflation expectations, which feed into longer-term bond yields and, in turn, mortgage pricing.
Rising Inventory Is Giving Buyers More Negotiating Power
The picture is not entirely negative for buyers. The National Association of Realtors reported that existing-home sales fell 2.0% in August to a seasonally adjusted annual rate of 3.98 million. It was the first time since June 2025 that sales fell below 4 million.
Supply is building. Total housing inventory reached 1.62 million units at the end of August, up 3.2% from July and 5.9% from a year earlier. It was the first time since November 2019 that inventory topped 1.6 million. At the current sales pace, that equals a 4.9-month supply, the highest in more than a decade. NAR Chief Economist Lawrence Yun said the larger supply gives buyers better opportunities to negotiate.
Prices are still rising, but more slowly. The national median existing-home price was $429,100 in August, up 1.6% from $422,400 a year earlier. NAR’s Housing Affordability Index was 104.7, up from 101.2 a year ago, as wage growth has outpaced price gains in many areas. NAR’s September sales data will be released October 13.
The Market Is Pulling in Two Directions
The September data point to a housing market with two competing forces. Buyers have more choice and more room to negotiate than at any point in years. Higher rates, however, are shrinking the amount they can borrow, which offsets much of that advantage.
For current homeowners, refinancing has largely stopped. With the refinance index 62% below last year’s level, few borrowers holding loans below today’s rates have a financial reason to refinance. That also keeps many homeowners from listing, since selling would mean giving up a lower rate.
For real estate agents, lenders, and home-related small businesses, the next few weekly readings will matter. Another MBA print near 7.1% would suggest rates are settling at a higher level. A quick reversal would mark the September spike as temporary. The October 28 FOMC decision and upcoming inflation data are the main events to watch.

FAQs
What is the current 30-year mortgage rate?
The Mortgage Bankers Association reported an average 30-year fixed conforming rate of 7.12% for the week ending September 18, 2026. Freddie Mac’s survey showed 6.95% as of September 17.
Why are mortgage rates going up?
Mortgage rates track the 10-year Treasury yield, which reached its highest level since 2007 on September 23. Elevated inflation, higher energy costs, and the Federal Reserve’s September 16 rate increase have all pushed yields higher.
Why are more borrowers choosing adjustable-rate mortgages?
The 5/1 ARM rate fell to 6.10%, more than a percentage point below the 30-year fixed rate. That lower initial rate reduces monthly payments during the fixed period, which pushed the ARM share of applications up to 9.8%.
Is it a buyer’s market in 2026?
Inventory reached 1.62 million homes in August, a 4.9-month supply and the highest in more than a decade, giving buyers more room to negotiate. Higher mortgage rates, however, reduce how much buyers can afford.
When is the next Federal Reserve meeting?
The next Federal Open Market Committee decision is scheduled for October 28, 2026. The Fed raised its target range to 3.75%–4.00% at its September 16 meeting.
