Stay informed on bi-merge credit report developments and how they impact your mortgage business. Here's what you need to know about FHFA's proposal, industry response, and the decision to maintain tri-merge as the standard for GSE lending.
| November 2025 (Current Status)
Bi-Merge Remains Cancelled, Tri-Merge Still Required
As of November 2025, bi-merge credit reporting remains cancelled for GSE lending. Lenders must continue using tri-merge credit reports (pulling from all three credit bureaus: Equifax, Experian, and TransUnion) when delivering loans to Fannie Mae and Freddie Mac. FHFA Director Bill Pulte has maintained the tri-merge requirement despite ongoing industry debate, with some organizations like the Mortgage Bankers Association advocating for single-report models while credit bureaus and others support maintaining tri-merge.
What This Means for You
You must continue pulling credit reports from all three bureaus for conforming loans. Your systems, workflows, and costs are based on the tri-merge standard that has been in place for decades. There is no implementation timeline for bi-merge, and Director Pulte has indicated tri-merge will stay in place as an "interim step" while the agency focuses on expanding credit scoring competition.

Mortgage Bankers Association Calls for End to Tri-Merge
The Mortgage Bankers Association's Residential Board of Governors passed a resolution formally advocating for an end to the tri-merge requirement, with MBA President Bob Broeksmit calling tri-merge an "outdated relic" from when data was fragmented. The MBA argued that a single-report requirement would lower costs and improve service quality, mirroring auto loan and home equity markets. However, this position directly contradicts credit bureau trade groups and some lawmakers who support maintaining tri-merge.
FHFA Clarifies Lender Choice Model
FHFA clarified that lenders may choose between Classic FICO or VantageScore 4.0 under a "lender choice" model, giving originators flexibility in which scoring system to use. The agency also confirmed that the tri-merge credit report requirement remains in place, reversing an earlier plan to move to bi-merge reports.

The decision maintains the long-standing requirement for lenders to pull credit reports from all three national bureaus, with Director Pulte clarifying additional details on July 15, 2025.

TransUnion Analysis Reveals Borrower Impact Concerns
TransUnion released analysis estimating that 2 million consumers could become ineligible for GSE loans under bi-merge, with 600,000 borrowers per year potentially paying higher interest rates. The study projected affected borrowers would pay an additional $6,600 in interest over the life of a mortgage due to incomplete credit data.

FHFA Proposes Shift to Bi-Merge Credit Reports
FHFA announced validation and approval of FICO 10T and VantageScore 4.0 credit score models, and simultaneously proposed transitioning to bi-merge credit reporting. The agency cited goals of reducing costs for borrowers, increasing competition among credit bureaus, and promoting market competition while maintaining information needed for robust risk management.

Tri-Merge Established as Industry Standard
Tri-merge credit reports from Equifax, Experian, and TransUnion were the established standard for GSE-backed mortgage underwriting. The middle score of the three bureau reports was used to determine borrower eligibility and pricing, providing the most complete view of borrower creditworthiness.
