Adjustable-rate mortgages are having a moment they have not had in years. The ARM share of mortgage applications climbed to 8.0 percent in the last week of August, its highest level in five weeks, according to the Mortgage Bankers Association’s weekly survey as reported by Mortgage News Daily. It is a small percentage on paper, but the direction matters more than the number: fixed-rate buyers are increasingly deciding a lower introductory payment is worth the long-term risk.
Why Buyers Are Suddenly Interested in a Riskier Loan
The average rate on a 5/1 ARM slipped to 5.94 percent even as fixed rates pushed toward multi-month highs, per Mortgage News Daily’s reporting on the MBA data. That gap is exactly what is pulling buyers toward adjustable products: a meaningfully lower rate for the first several years of the loan, in exchange for payments that can reset higher once the fixed period ends. MBA’s chief economist pointed to rising investor concern over inflation and growing federal deficits as the forces pushing yields — and therefore fixed mortgage rates — higher across the board, a dynamic CNBC has also tracked as ARM demand rises in tandem with rate pressure.
Purchase Demand Is Holding, Barely
Overall mortgage application volume rose 0.8 percent for the week, with purchase applications up 2 percent week-over-week even though they remained 0.2 percent below year-ago levels, according to Mortgage News Daily. That is a buyer pool that has not given up, even with rates hovering near 7 percent — it has just started reaching for a different kind of loan to make the math work. Refinancing told the opposite story, falling 1 percent for the week and sitting 19 percent below last year’s pace, as homeowners who locked in lower rates years ago have little incentive to refinance into today’s environment.
A Comeback With a Catch
ARMs carry a reputation problem dating back to the 2008 housing crash, when borrowers who did not understand their loans’ reset terms were blindsided by payment jumps they could not afford. Today’s ARM products are structurally different, with rate caps and longer fixed-rate introductory periods built in specifically to prevent a repeat of that scenario. Still, the fundamental trade-off has not changed: a lower payment now in exchange for uncertainty later. As more buyers make that trade to get into a home at all, the real test will come in a few years, when the first wave of this rate cycle’s ARMs reach their adjustment period and homeowners find out exactly how much their monthly payment is about to change.
