Borrowers pivot to adjustable loans as application volume slides in week ending Sept. 4
Total mortgage application volume fell 2.7% for the week ending September 4, as the 30-year fixed rate climbed to its highest point since June 2025. That drove a notable shift toward adjustable-rate products among cost-sensitive borrowers, according to data released Wednesday by the Mortgage Bankers Association (MBA).
"Mortgage rates moved higher last week, driven by ongoing investor concerns over inflation and the federal budget deficit. The 30-year fixed rate increased to 6.85%, the highest since June 2025 and 36 basis points higher than a year ago," said Joel Kan, CMB, MBA's Vice President and Deputy Chief Economist.
ARM share climbs to highest level since June
With conforming 30-year costs elevated, demand for adjustable-rate mortgages (ARMs) climbed to 8.5% of total applications, the highest share since June.
The 5/1 ARM rate moved counter to that trend, easing to 5.82% from 5.94%, widening its spread over the conforming 30-year rate to more than 100 basis points. That gap is increasingly drawing payment-sensitive borrowers toward products that carry rate-reset risk.
As buyers retreated when mortgage rates climbed to their highest in over a year earlier this summer, the rotation toward ARMs has grown progressively more pronounced.
The FHA share of applications rose to 17.2% from 15.9%, suggesting continued demand from first-time and lower-income buyers entering the market despite elevated rates.
The VA share, meanwhile, fell to 12.0% from 13.6%. Jumbo 30-year rates eased slightly to 6.74% from 6.76%, while the 15-year fixed rose to 6.17% from 6.14%.

Refinances retreat, purchase volume holds
The Refinance Index dropped 6% for the week, falling to its slowest weekly pace since May 2025 and landing 25% below the same period a year earlier.
The refinance share of total applications slipped to 40.9% from 41.8%.
For much of 2026, mortgage applications stalling through summer as rate inertia squeezed buyers has defined the market's pattern, and September's first reading suggests no shift.
Purchase activity proved more durable. The seasonally adjusted Purchase Index eased just 0.2% for the week, and year-over-year, purchase applications remain 4% ahead of the same period in 2025.
Kan acknowledged the persistent friction, saying, "Higher mortgage rates continue to weigh on prospective homebuyers looking to act, even as housing inventory has increased in many markets."
For brokers, the qualification threshold has tightened in step with rates. Nicholas Barta, division president at Security First Financial in Colorado, addressed the dynamic in comments to Mortgage Professional America earlier this year.
"There's not as many people that will qualify to purchase homes, or they can't qualify to purchase the homes that they want because they qualify at a lower level," Barta said.
Rates have climbed roughly 75 basis points since late February, as escalating geopolitical tensions in the Middle East drove energy prices higher and stoked inflation concerns.
Consumer price data for August due Friday is expected to show annual headline inflation running near 3.4%, a figure Federal Reserve officials are tracking as they assess the path for interest rates. Until clearer policy signals emerge, rate paralysis has become a recurring constraint on originator pipeline volume with little near-term sign of relief.
