The Federal Housing Finance Agency (FHFA) is preparing to issue a directive to government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac to transition from the long-standing “tri-merge” credit report requirement to a “bi-merge” system for loan deliveries. This significant policy shift, which is expected to be formalized within the coming weeks, represents a major overhaul of the mortgage underwriting process in the United States. According to sources familiar with the matter, FHFA Director Bill Pulte is anticipated to officially announce the change during the Mortgage Bankers Association (MBA) Annual Convention and Expo in Chicago on October 12.
The move aims to modernize the credit reporting landscape, reduce closing costs for prospective homebuyers, and introduce greater competition among the nation’s three primary credit bureaus: Equifax, Experian, and TransUnion. Under the new mandate, lenders will no longer be required to pull credit reports from all three bureaus to meet GSE standards. Instead, they will have the flexibility to utilize data from only two of the agencies, a move that could significantly alter the financial dynamics of the credit reporting industry.
The Evolution of Mortgage Credit Requirements
For decades, the “tri-merge” report has been the gold standard for residential mortgage lending in the United States. This process involves a lender pulling a credit report and score from each of the three national credit bureaus and using the middle score of the three to determine a borrower’s creditworthiness. While this system provided a comprehensive view of a consumer’s credit history, it also mandated a captive market for the bureaus, as lenders had no choice but to pay for all three reports for every conventional loan application.
The transition to a bi-merge model is not an entirely new concept within the halls of the FHFA. The initiative was initially explored during the Biden administration under the leadership of then-Director Sandra Thompson. At that time, the FHFA argued that moving to a bi-merge system would maintain high standards for risk management while lowering costs. However, the plan faced significant headwinds from industry stakeholders who cited implementation challenges, technical hurdles, and concerns regarding the potential loss of critical credit data if one bureau’s records were excluded. Consequently, the transition was delayed to allow for further study and industry preparation.
The momentum shifted again in early September when current FHFA Director Bill Pulte signaled a renewed and more aggressive focus on the issue. In a series of public statements, Pulte criticized the pricing practices of the major credit bureaus, suggesting that the current system fostered an environment where companies could "overcharge" American consumers. This rhetoric set the stage for the upcoming directive, positioning the bi-merge shift as a consumer-protection measure designed to curb rising mortgage transaction costs.
Strategic Objectives and the Push for Competition
The FHFA’s decision is rooted in a broader strategy to introduce market pressure on credit reporting agencies. By allowing lenders to select two out of the three bureaus, the FHFA effectively ends the guaranteed revenue stream that each bureau enjoyed under the tri-merge requirement. This is expected to force Equifax, Experian, and TransUnion to compete more aggressively on price and service quality to ensure they are one of the two bureaus selected by lenders.
Director Pulte’s recent social media communications underscored this sentiment. He stated that the three bureaus have been "overcharging Americans for far too long" and pledged that the FHFA would no longer allow these entities to take advantage of consumers. Beyond the bi-merge transition, Pulte hinted at even "stronger solutions" under the monikers of SAFER (Secure and Fair Evaluation of Risk) and SOUNDER (Systemic Oversight Under New Data and Evaluation Rules), indicating that the bi-merge move is part of a multi-phased approach to credit reform.
The cost implications for consumers are substantial. Over the past two years, the mortgage industry has seen a sharp increase in the fees charged by credit bureaus for tri-merge reports. Some lenders have reported that the cost of a single credit pull has more than doubled, adding hundreds of dollars to the upfront costs of a mortgage application. In an environment of elevated interest rates and high home prices, the FHFA views the reduction of these administrative fees as a critical lever for improving housing affordability.
Chronology of Credit Reform Milestones
The path toward the bi-merge transition has been marked by several key regulatory milestones over the past year:
- Late 2022 – Initial Proposal: The FHFA first announces its intention to explore alternatives to the tri-merge requirement under Sandra Thompson, citing the need for competition.
- Spring 2023 – Implementation Delay: Following feedback from the Mortgage Bankers Association and other trade groups regarding operational readiness, the FHFA pauses the bi-merge rollout.
- Late 2023 – Inclusion of VantageScore: The FHFA approves the use of VantageScore 4.0 alongside the traditional "Classic FICO" scores, breaking FICO’s long-standing monopoly on GSE credit scoring.
- September 2024 – Pulte’s Public Mandate: Director Bill Pulte takes to social media to announce that the FHFA is "seriously considering" the bi-merge adoption to combat bureau overcharging.
- October 2024 – Unified Pricing Grid: The FHFA releases a single pricing grid that treats VantageScore 4.0 and Classic FICO scores as equivalents, reversing previous assumptions that VantageScore might overstate creditworthiness.
- Expected October 12, 2024 – Formal Announcement: The bi-merge directive is anticipated to be unveiled at the MBA conference in Chicago.
Technical Implications: VantageScore and the Unified Grid
A critical component of the bi-merge transition is the integration of newer, more modern credit scoring models. The FHFA recently finalized a decision to allow Fannie Mae and Freddie Mac to use credit scores from VantageScore 4.0, a model developed as a joint venture by the three major bureaus. This serves as a contemporary alternative to the "Classic FICO" models (FICO 2, 4, and 5) that have governed the mortgage industry for decades.
Earlier this week, the FHFA took a significant step by implementing a unified Loan-Level Price Adjustment (LLPA) grid. Previously, GSE grids were structured with a bias that assumed VantageScore 4.0 scores were roughly 20 points more optimistic than FICO scores for the same borrower. The new unified grid removes this disparity, treating a 720 VantageScore as identical in risk to a 720 FICO score.
This alignment is essential for the bi-merge system to function efficiently. If lenders are to choose between bureaus and scoring models, the regulatory framework must ensure that the resulting risk assessments are consistent across the board. By standardizing the pricing for both FICO and VantageScore, the FHFA is removing a significant barrier that had previously discouraged lenders from adopting newer scoring technology.
Industry Reactions and Stakeholder Concerns
The reaction from the mortgage industry has been a mix of cautious optimism and operational concern. The Mortgage Bankers Association (MBA) has been a vocal participant in this dialogue. While the MBA has historically supported efforts to reduce costs, it has also advocated for a "single-file" option in certain scenarios to maximize efficiency.
Proponents of the bi-merge shift argue that the risk of missing critical credit information is minimal. Modern credit reporting is highly redundant, and most significant credit events—such as bankruptcies, foreclosures, or major delinquencies—are reported to all three bureaus. Statistical analysis suggests that the difference in a borrower’s "middle score" between a tri-merge and a bi-merge is often negligible for the vast majority of applicants.
However, some credit experts warn that the bi-merge could potentially disadvantage "thin-file" borrowers—those with limited credit histories who may only have data reported to one of the three bureaus. If a lender happens to pull reports from the two bureaus that do not have the borrower’s information, that consumer could be unfairly denied a loan or charged a higher interest rate. Addressing these "edge cases" remains a primary focus for consumer advocacy groups as the implementation date approaches.
Broader Economic Impact and Future Outlook
The transition to a bi-merge system is expected to take effect between one and three months after the official announcement. During this window, mortgage technology providers, loan origination systems (LOS), and lenders will need to update their software and internal protocols to accommodate the new delivery requirements.
Beyond the immediate cost savings for borrowers, this move signals a fundamental shift in the relationship between the federal government and the private credit reporting industry. By leveraging the massive market power of Fannie Mae and Freddie Mac—which back the majority of residential mortgages in the U.S.—the FHFA is effectively dictating new terms of engagement for the credit bureaus.
If successful, the bi-merge initiative could pave the way for further streamlining of the mortgage process. As digital data verification tools for income, employment, and assets become more prevalent, the traditional credit report may eventually see even further competition from alternative data sources, such as rent and utility payment histories.
As the industry gathers in Chicago for the MBA conference, all eyes will be on Director Bill Pulte. His expected announcement will not just be a change in policy, but a declaration that the FHFA intends to use its regulatory authority to reshape the financial infrastructure of the American dream, prioritizing affordability and competition in an increasingly expensive housing market.
