US: adjustable-rate loans pass 11% of rate locks as 30-year index hits 7.2%

With the 30-year fixed index at 7.2%, adjustable-rate mortgages took more than 11% of US rate locks, trading a lower payment today for a reset later.

The facts

The Conforming 30-year Fixed Rate Index reached 7.2% on 24 September.
Adjustable-rate mortgages took more than 11% of rate locks, their largest share in nearly four years.
Active first-lien adjustable-rate loans number 3.1 million, the most in 5.5 years, but just 5.6% of active mortgages.
Only about a third have begun adjusting; more than 90% of those originated since 2022 are still in their introductory fixed period.
Around 180,000 reach their first reset next year, and roughly 74,000 seven-year loans from 2020 face the largest median rise, about 1,066 USD a month or 36%.

What it means for your money

Fixed borrowing is expensive, so more buyers take an adjustable rate. That trades a lower payment now for a reset later.
On a full 25-basis-point pass-through to the underlying indexes, the median affected payment rises about 14 USD a month, and roughly 53 USD on more recently originated loans.
Glopra's United States data puts the typical home value at 369,678 USD and the typical asking rent at 1,948 USD a month, with an effective 10.66% tax on rental income under the net-basis election.
An owner already holding one of these loans should read the reset calendar rather than the 30-year fixed index.

What to watch

Property insurance moved independently of the loan: average annual costs fell 6.6% for owners who switched carriers and rose 10.4% for the rest.
Home-equity lines follow the prime rate and reset monthly, where 25 basis points would add roughly 9 USD to the median monthly payment.
