Fair Isaac (FICO) shares fall sharply after the FHFA announces that Fannie Mae and Freddie Mac will use a single mortgage pricing grid that includes both FICO and VantageScore scores. Traders react to the change as it increases the ability of mortgage lenders to choose between competing credit scoring models for GSE-backed loans.

FHFA Director William J. Pulte says the GSEs are “simplifying mortgage pricing” by replacing two pricing grids with one that brings VantageScore 4.0 into the existing FICO Classic pricing framework. Multiple outlets report that this alters how lenders’ loan-level pricing adjustments (LLPAs) can apply, potentially reducing the advantage of using FICO in some cases. Analysts quoted by outlets also warn the shift can change incentives in the mortgage market, including the risk of “score shopping,” where lenders seek whichever scoring model results in better pricing.

Separately, Rocket Mortgage announces it will use VantageScore 4.0 as its preferred scoring model for all eligible loans delivered to the GSEs and other programs. Outlets frame this as an early signal of how quickly lenders could adopt the new approach, intensifying concerns about FICO’s pricing power and “moat.” Rocket’s rationale emphasizes expanded access and lower scoring-related costs, while FICO faces investor concerns about margins. (All sources describe the market reaction as steep on the announcement’s first trading day.)
