Independent mortgage banks (IMBs) reported a sharp decline in profitability during the fourth quarter of 2025, with profit margins falling 44% to $674 per loan from $1,201 in Q3, according to Mortgage Bankers Association data.

The margin compression was driven by declining revenues, which slipped to 340 basis points during the quarter. This represents a significant squeeze on lender economics as the mortgage industry navigates challenging market conditions.
