The Next Mortgage Shock Has Been Scheduled -- Homeowners Could See Their Monthly Payments Jump $1,066 in 2027

Tens of thousands of homeowners who secured adjustable-rate mortgages (ARMs) during the pandemic are facing an impending financial challenge as their loans are set to reset in 2027. In 2020, approximately 74,000 households opted for seven-year ARMs, which will soon reach the end of their fixed-rate period. According to the October Mortgage Monitor report from Intercontinental Exchange, the median borrower among this group is expected to experience a staggering increase in monthly payments, estimated to rise by $1,066, or 36%. This translates to an annual increase of nearly $12,800 in housing costs, which comes at a time when many homeowners are already grappling with higher insurance and property tax expenses.

While the overall market appears to be more stable, with ICE reporting that only 180,000 ARMs will reset in 2027 out of 3.1 million active ARMs nationwide, this represents just 5.6% of outstanding mortgages. For most ARM holders, a modest increase of 25 basis points in interest rates would lead to an approximate $14 increase in their monthly payment. The majority of the stress, however, is concentrated among those who borrowed in 2020.

The financial outlook for these 2020 borrowers has worsened significantly this fall. On October 8, the yield on the 10-year Treasury note reached 5.22%, representing a 0.42 percentage point increase in just one month and nearing a yearly high of 5.31%. Additionally, Brian Brown, president and CFO of Rocket Companies, noted in August that the 30-year fixed mortgage rate had climbed to 6.8%, the highest in over a year. Refinancing into a fixed-rate mortgage at these elevated rates would result in a permanent payment shock for borrowers. Selling their homes could provide a cleaner exit, and rising property values could be beneficial; the Case-Shiller national index reported a 1.9% increase over the past year, indicating that most homeowners have built up significant equity.

Major mortgage servicers are anticipating an influx of refinancing inquiries from this cohort. Rocket Companies manages a servicing portfolio valued at $2.0 trillion, with 57% of its refinance closings last quarter coming from existing clients. Rocket also leads the nation in home equity lending, enabling homeowners to access cash without impacting their primary mortgage. PennyMac Financial Services has also reported an increase in its refinance recapture rates, with a government rate of 59% and a conventional rate of 29%.

Despite these efforts, investor confidence in the ability of lenders to capitalize on refinance demand appears low. Rocket's stock has plummeted by 40.7% this year, while PennyMac has seen a 54.08% decline, as its annualized return on equity fell dramatically from 14% to just 2%.

Private mortgage insurers are beginning to feel the effects of increasing delinquencies. MGIC Investment reported a rise in its primary delinquency rate from 2.21% to 2.37% year-over-year. CFO Nathan Colson described this trend as part of a broader normalization of credit. Essent Group experienced a sharper increase, with its default rate climbing from 2.12% to 2.53%, claim severity rising to 85% from 67%, and loss provisions nearly tripling to $49 million.

Despite these challenges, the market continues to regard both MGIC and Essent as stable entities. MGIC's stock has only declined by 4.54% this year, while Essent's has dropped by 2.2%. Essent's CEO, Mark Casale, suggests that the equity in insured homes could help mitigate future claims, especially as home prices continue to rise.

As the 2027 resets approach, the situation for these borrowers will serve as a crucial test of how pandemic-era mortgage holders manage a potential 36% increase in payments amid rising interest rates. MGIC is set to hold its third-quarter earnings call soon, and if its delinquency rates rise more sharply than the seasonal increases Colson anticipates for the latter half of the year, the narrative of normalization may weaken. Observers should also monitor Essent for any changes in claim severity, particularly if it remains around the current level of 85%.

A larger issue is already emerging, as ARMs now represent over 11% of rate locks, marking the highest percentage in nearly four years. Current ARM borrowers are starting from significantly higher rates than those in the 2020 group, setting the stage for another wave of resets in the near future.
