Millions of Adjustable-Rate Mortgages Are Resetting — and Many Homeowners Can't Afford the New Payments
Published: January 8, 2026 | By Mariusz Kurylo
When mortgage rates were at their pandemic-era lows of 2.5–3.5% in 2020–2022, a specific class of homebuyer sought to maximize their purchasing power by taking adjustable-rate mortgages rather than 30-year fixed loans. These ARMs offered initial fixed-rate periods — typically 5 or 7 years — before adjusting annually to a spread over a benchmark index. A buyer who took a 5/1 ARM in 2021 at 2.75% was aware, at least in principle, that the loan could adjust upward in 2026. That adjustment period had now arrived, and for many of these borrowers, the mathematical reality of the reset was proving far more severe than they had anticipated or prepared for.
The Mortgage Bankers Association reported that approximately 1.4 million adjustable-rate mortgages originated between 2019 and 2022 were scheduled to have their first interest rate adjustment in 2025–2026, according to Reuters coverage of the MBA's mortgage finance data. The adjustment mechanics for most contemporary ARMs tied the post-adjustment rate to the Secured Overnight Financing Rate (SOFR) — the benchmark that had replaced LIBOR — plus a margin of typically 2.5 to 3 percentage points. With SOFR running near 4.5% in early 2026, a borrower whose ARM was resetting would face a new rate of approximately 7–7.5%.
For a borrower who had taken a $450,000 ARM at 2.75% in 2021, the original monthly payment was approximately $1,837. After reset to 7.25%, the new payment on the remaining balance (approximately $420,000 after five years of amortization) would be approximately $2,867 — an increase of $1,030 per month, or approximately 56%. Bloomberg calculated that this payment shock was the largest average ARM reset magnitude since the 2007–2008 subprime ARM crisis, though the current situation differed importantly from that period in the quality of the underlying borrowers.
Who Took Out ARMs in 2020–2022 — and Why
Understanding the demographic distribution of the current ARM reset wave helps assess the default risk and human impact. Unlike the 2005–2007 ARM boom, which was concentrated in subprime borrowers who often had limited understanding of the reset terms they had agreed to, the 2020–2022 ARM originations were predominantly in two borrower categories.
The first category was jumbo mortgage borrowers — buyers financing home purchases above the conforming loan limit (approximately $750,000 in high-cost markets) who were ineligible for Fannie Mae and Freddie Mac backing and who bought ARMs for the rate advantage relative to jumbo fixed-rate loans. These were disproportionately upper-income, high-credit-score borrowers in expensive coastal markets. Bloomberg reported that jumbo ARM originations as a share of jumbo mortgage originations reached approximately 40% in 2021 in markets like San Francisco, Los Angeles, and New York — substantially above the historical norm — as buyers stretched to afford expensive homes in a competitive market.
The second category was non-QM (non-qualified mortgage) borrowers — self-employed individuals, real estate investors, and others who did not qualify for conventional agency financing but accessed the mortgage market through private label lenders. Non-QM ARMs often had higher initial rates than conventional ARMs but still offered a spread versus fixed non-QM loans, and were popular among real estate investors who expected to sell or refinance before adjustment.
Wall Street Journal analysis of Ginnie Mae and private label servicing data showed that the payment shock was distributed across both categories, but the consequences differed by borrower type. High-income jumbo borrowers were absorbing higher payments as a budget stress rather than an existential financial crisis — painful but not foreclosure-inducing for most. Non-QM investors, particularly those who purchased rental properties with the assumption of rent income sufficient to cover payments, faced a more precarious situation when the reset increased payments faster than rents.
Servicer Options for Struggling Borrowers
For borrowers genuinely unable to afford their reset payments, the servicer — the company responsible for collecting mortgage payments and managing delinquencies — had a range of modification options. Under federal regulations implemented after the financial crisis, servicers were required to evaluate distressed borrowers for loan modification before proceeding to foreclosure, and the modification toolkit included options such as loan term extension (reducing payment by spreading principal over a longer period), principal deferral (setting aside a portion of principal as a non-interest-bearing balloon payment), or in some cases, interest rate reduction.
CNBC reported that mortgage servicers were reporting increased modification requests in late 2025 and early 2026, and that processing capacity was becoming a concern at some smaller non-bank servicers who had not invested adequately in loss mitigation infrastructure. The Consumer Financial Protection Bureau (CFPB) issued guidance reminding servicers of their obligation to engage with distressed borrowers promptly and to offer all available modification options before foreclosure referral.
For borrowers in jumbo non-agency loans, the modification landscape was more complex. Unlike government-backed loans (FHA, VA, Fannie, Freddie) where modification programs were standardized and servicers had strong incentives to use them, private label loan modifications required negotiation with the relevant RMBS trust special servicer — a process that could take months and produced less certain outcomes.
The Comparison to 2007–2008: Key Differences
The ARM reset wave of 2026 inevitably invited comparison to the 2007–2008 subprime ARM crisis that helped trigger the financial crisis. The similarities were real: large numbers of borrowers facing payment shocks, concentrated in specific market segments and geographies, in an environment of declining home prices that limited refinancing options.
But the Financial Times identified three critical differences. First, current ARM borrowers had significantly higher credit quality than 2007 subprime ARM borrowers — they had larger down payments, higher incomes, and better documentation of their financial positions. Second, today's market had far fewer "option ARM" or "negative amortization" loans — products that allowed borrowers to pay less than required interest in the early years, with the unpaid interest added to the principal balance. These instruments, which were common in 2005–2007, were effectively eliminated after the crisis. Third, home prices nationally, while having declined modestly, were still well above 2021 purchase prices for most borrowers — meaning most ARM borrowers were still in positive equity positions and had refinancing options that 2007 borrowers lacked.
The net assessment from Bloomberg economists was that the ARM reset wave would contribute to elevated delinquency rates and some increase in foreclosures in 2026, but was unlikely on its own to produce a systemic housing crisis. The risks were most concentrated in geographic markets with the sharpest price corrections, among investors with leveraged rental property portfolios, and among non-QM borrowers with thinner financial cushions.
