ARM Demand Hits Nearly Four-Year High as Borrowers Seek Relief From Higher Fixed Rates

Adjustable-rate mortgages are taking a larger share of the mortgage market as borrowers search for payment relief from higher fixed rates, but the stock of existing ARM loans remains far smaller than it was before the financial crisis.

The October 2026 ICE Mortgage Monitor found that ARMs accounted for more than 11% of mortgage rate locks, their largest share in nearly four years, as ICE’s conforming 30-year fixed-rate index reached 7.2% on Sept. 24.

ICE counted 3.1 million active first-lien ARMs, the most in 5½ years, but they represent only 5.6% of active mortgages. More than 90% of ARMs originated since 2022 remain in their introductory fixed-rate periods, meaning the recent increase in ARM production has not yet translated into widespread payment resets.

“ARMs are becoming more attractive to borrowers looking for relief from today’s higher fixed rates, but the overall market exposure to adjustable payments remains relatively limited,” Andy Walden, ICE’s head of Mortgage and Housing Market Research, said in the report.

The ARM comeback is about the payment gap

The renewed appeal of adjustable-rate loans reflects a basic affordability calculation. When fixed mortgage rates rise rapidly, the initial rate on an ARM can offer borrowers a lower monthly payment, particularly for buyers who expect to move, refinance or otherwise change the loan before the first adjustment.

That does not make the product risk-free. ARM borrowers accept uncertainty about future payments once the introductory period ends. But ICE’s data show why today’s ARM market is structurally different from the pre-2008 period: adjustable loans are a relatively small share of the active mortgage universe, and most newer loans have not begun resetting.

Only about 1.05 million active ARM loans have reached their first reset and are currently operating as adjustable-rate loans, according to ICE. That is the lowest number in more than 25 years. Most post-reset ARMs were originated more than a decade ago and already experienced adjustments during the Federal Reserve’s 2022-2023 tightening cycle.

Recent Fed move has limited immediate ARM impact

ICE also modeled the effect of the Federal Reserve’s recent 25-basis-point rate increase. Assuming the full move passes through to the indexes underlying adjustable-rate mortgages, the median affected borrower would see a monthly payment increase of about $14.

That modest near-term impact is important for servicers. The headline growth in ARM demand does not, by itself, imply a wave of immediate payment shocks. Reset timing, caps, loan vintage and the benchmark tied to each mortgage all affect when and how much a borrower’s payment can change.

At the same time, the market is moving toward more payment-sensitive behavior. Borrowers are increasingly willing to consider adjustable structures and to pay upfront costs to reduce their initial mortgage rate, ICE found. Both trends are consistent with a market in which monthly affordability, rather than simply the home price, is driving product choice.

Servicing risk remains concentrated elsewhere

The ARM findings arrive against a mortgage-performance backdrop that remains broadly stable but is showing pockets of stress. In ICE’s August 2026 First Look, the national delinquency rate rose 14 basis points to 3.53%, largely because of calendar effects. Serious delinquencies increased by 11,000 to 574,000 and were 19% above a year earlier, although the serious-delinquency rate of 1.04% was essentially in line with the 2017-2019 August average.

Foreclosure starts fell 6% in August, while the pre-sale foreclosure inventory rate held at 0.54%. ICE said active foreclosure inventory was up 41% from a year earlier, but foreclosure sales were still running at only 57% of their August 2019 pace.

Those figures suggest the principal near-term servicing concern is not a broad ARM reset shock. Instead, lenders and servicers are navigating a mix of higher borrowing costs, rising serious delinquencies in parts of the portfolio and a purchase market increasingly shaped by borrowers seeking ways to lower the initial payment.

Why it matters for lenders

For originators, the ARM resurgence creates both an opportunity and a suitability challenge. A lower introductory rate can expand purchasing power, but the loan’s adjustment mechanics, caps and potential future payment path become more important when rates are volatile.

For servicers, the small share of currently adjusting ARMs limits immediate systemic exposure. The longer-term question is what happens when the newer 2022-2026 ARM vintages begin reaching their first adjustment dates — and whether borrowers have an affordable refinance option when they do.

ICE’s data make the current picture clear: borrowers are adapting to higher rates, but they are not recreating the ARM-heavy mortgage market that preceded the financial crisis. The product is growing from a historically small base, and most of the risk associated with today’s new ARM production remains several years in the future.
