Mortgage Applications Fall 2.7% as Buyers Shift to ARMs

Mortgage applications fell 2.7% in the week ending September 4, 2026. The Mortgage Bankers Association reported this decline in seasonally adjusted data. Purchase applications slipped 0.2% week-over-week. They sit 4% below the same period in 2025. Refinance applications dropped 6%. This figure is 25% lower than the year-earlier level.

Borrowers are moving toward riskier loan structures. Adjustable-rate mortgages now account for 8.5% of applications. This is the highest share since June. Joel Kan, MBA vice president, noted that higher rates continue to weigh on buyers. Housing inventory has increased in many markets. Demand remains weak despite the supply growth.

Fixed rates rise while ARM costs fall

The average 30-year fixed mortgage rate increased to 6.85% from 6.79%. Thirty-year jumbo rates climbed to 7.08%. Adjustable-rate mortgage rates declined to 5.82% from 5.94%. This spread drives borrowers toward initial lower payments. ARMs typically offer lower starting rates than fixed loans. Payments can rise sharply after the introductory period ends.

Risk premium drives borrower behavior

Lenders set 30-year mortgage prices using the 10-year Treasury yield. They add a risk premium to this benchmark. Many loans are paid off or refinanced within eight to 11 years. Credit scores and loan terms also influence final pricing. Broader economic conditions affect overall mortgage costs. Buyers must compare offers beyond the advertised rate.

Affability remains a major obstacle

GN auto markets/housing: mortgage rates data shows sustained pressure. Elevated rates keep some buyers on the sidelines. Others accept variable payment risks to enter the market. The shift to ARMs signals a trade-off for lower initial costs. Historical data links ARM defaults to the 2008 housing crash. Borrowers must understand when rates can reset. They need to estimate potential future payment increases.
