Rising Mortgage Rates | Why Borrowers are Choosing ARMs

Mortgage Demand and the Rise of ARMs

Borrowers are increasingly gravitating toward adjustable-rate mortgages as fixed-rate borrowing costs climb. The share of adjustable-rate mortgages in total application volume reached 8.5% last week. This is the highest level observed since June 2026.

During the initial years of the pandemic, low interest rates pushed the demand for these variable loans down to approximately 3%. The current shift marks a clear reversal from that period of stability. Borrowers are seeking out these products as a way to find savings in a tightening credit environment.

The Cost of Borrowing

Interest rates on standard loans continue to climb. The average contract interest rate for a 30-year fixed-rate mortgage with a conforming loan balance rose to 6.85% last week. This figure was 6.79% the previous week. Points also increased, moving to 0.67 from 0.65.

Fixed-rate loans for balances of $832,750 or less are now more expensive than at any point since June 2025. This 36-basis-point increase over the past year adds significant pressure to monthly payments for prospective homeowners. By comparison, the five-year adjustable-rate mortgage saw its average rate decline to 5.82% from 5.94%.

Market Impact and Future Outlook

Rising interest rates are cooling total mortgage application volume. The Mortgage Bankers Association reported a 2.7% decline in total volume for the week, based on its seasonally adjusted index. Refinance applications saw the sharpest drop, falling 6% over the same period. They are now 25% lower than they were one year ago.

Joel Kan, vice president and deputy chief economist at the Mortgage Bankers Association, noted that concerns regarding inflation and the federal budget deficit drive these higher rates. While purchase applications remain relatively stable, down only 0.2%, the broader market feels the weight of increased borrowing costs. High inventory levels in certain regions have not been enough to overcome the barrier of expensive financing.

Market participants are currently focused on upcoming inflation data. The release of these figures later this week could trigger volatility in mortgage rates. The long-term trajectory of the housing market depends heavily on how the Federal Reserve and bond investors react to these indicators. Prospective buyers remain in a holding pattern as they monitor the shifting rate environment for signs of relief.
