Mortgage Underwriting at the Largest Banks

In 2026 Q2, half of the first-lien mortgages made by the largest U.S. banks went to borrowers whose total monthly debt payments, including the new mortgage, took up 36% of their monthly income or more. A quarter of borrowers were at 43% or higher, and one in ten at 48% or higher.

The median borrower had a credit score of 775, and only one in ten scored below 704. The median loan was $376,185. The median loan-to-value ratio was 75%, meaning the loan covered three-quarters of the home’s price or appraised value. One in ten loans was at 95% or higher.

These banks originated $88.66 billion in first-lien mortgages that quarter. Adjustable-rate mortgages accounted for $28.29 billion of that, about 32% of the dollar volume.

What the figures measure

The numbers come from the FR Y-14M reports that the largest bank holding companies file with the Federal Reserve. The Federal Reserve Bank of Philadelphia publishes summary statistics, which are carried on FRED. They cover first-lien mortgages the banks originated and held in portfolio in each quarter, including loans later sold or securitized. They do not include mortgages made by smaller banks or by nonbank lenders.

  • Back-end debt-to-income (DTI): all monthly debt payments, including the proposed housing payment, divided by monthly income, at origination.
  • Loan-to-value (LTV): the loan amount divided by the lower of the sale price or the appraised value. Only loans with an LTV above 0% and below 125% are included.
  • Credit score: a commercially available credit score at origination.
  • Percentiles: the 90th percentile DTI of 48% means 90% of loans had a DTI at or below that level.

The adjustable-rate share is our calculation: ARM originations divided by total first-lien originations. The ARM series begins in 2013 Q3.
