ARM demand climbs to its highest application share in a year as buyers face borrowing costs near three-year highs
Mortgage applications declined for the seventh consecutive week as the 30-year fixed rate climbed to its highest point in nearly three years, cementing a demand freeze that has gripped US housing since rates began their latest ascent in late August.
The Mortgage Bankers Association (MBA) reported Wednesday that its Market Composite Index fell 2.7% on a seasonally adjusted basis for the week ending October 9.
Purchase applications dropped 4% week-over-week and were 16% lower than the same period a year ago, a sustained retreat that has not posted a weekly gain since late August.
The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances of $832,750 or less rose to 7.5% from 7.49%, its highest since November 2023 and more than a full percentage point above year-ago levels.
According to Freddie Mac data, rates have surged approximately 74 basis points since late August alone.
Adjustable-rate mortgages attract growing buyer share
As fixed-rate costs mount, adjustable-rate mortgages (ARMs) — home loans with a fixed introductory rate that later adjusts to prevailing market levels — are absorbing a rising share of demand.
ARM share in MBA’s weekly survey climbed to 10.5%, its highest since October 2025. The October 2026 Mortgage Monitor Report from Intercontinental Exchange, Inc. (ICE) confirms ARM demand has hit a near four-year high in rate lock data, with ARM share surpassing 11% of total locks in September.
“Borrowers continue to rely more on ARM loans to help lower their monthly payments,” said Joel Kan, Vice President and Deputy Chief Economist at the MBA in Washington, D.C.
Average 5/1 ARM rates rose to 6.54% from 6.43% the prior week, roughly a full percentage point below the 30-year fixed rate, giving cost-sensitive buyers meaningful monthly payment relief.
Optimal Blue’s September 2026 Market Advantage Report found that non-QM lock volume also rose even as total lock activity fell.
Brennan O’Connell, director of data solutions at Optimal Blue in the United States, told Mortgage Professional America that “people are, originators and borrowers, getting creative and figuring out different paths towards financing in an otherwise difficult environment.”
No relief expected through 2027
At the MBA’s annual conference Sunday, Chief Economist Mike Fratantoni in Washington, D.C., warned the rate environment reflects structural forces unlikely to resolve quickly.
“Inflation is too high, leading central banks to raise short-term rates, while budget deficits and debt are unsustainably high, leading bond investors to push up longer-term rates,” he said.
Fratantoni projected rates near 7.3% through year-end and above 7% through 2027.
Mike Fratantoni, Joel Kan, and Marina Walsh of the Mortgage Bankers Association expect mortgage originations to fall in 2027, with rates remaining above 7% and refinance opportunities staying limited despite steady purchase activity. https://t.co/3WmwWuhSWh

Refinance applications fell 0.4% for the week and were 56% below year-ago levels. National Association of Realtors (NAR) Chief Economist Lawrence Yun in Washington, D.C., noted that while US closed home sales rose 1.5% month-over-month in September, those transactions reflect summer market conditions.
“Further increases in mortgage rates in recent weeks mean fewer buyers can qualify to purchase a home,” Yun said.
