WASHINGTON — In what represents one of the most significant structural shifts in the American mortgage market in decades, the Federal Housing Finance Agency (FHFA) is reportedly preparing to direct government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac to abandon traditional "tri-merge" credit reporting in favor of a "bi-merge" model.
According to sources familiar with the matter who spoke on the condition of anonymity, the directive could be officially announced by FHFA Director Bill Pulte as early as October 12 during the upcoming Mortgage Bankers Association (MBA) annual conference in Chicago. The transition, which would alter a fundamental pillar of mortgage underwriting for loans sold to the GSEs, is expected to take effect within one to three months following the formal announcement.
If implemented, the change will dismantle a decades-long industry standard requiring lenders to pull credit data from all three major national credit bureaus—Equifax, Experian, and TransUnion—when evaluating a prospective homebuyer’s creditworthiness. Instead, lenders will be permitted to pull data from only two of the three reporting agencies, a move that regulators and industry advocates argue could inject much-needed competition into the credit bureau oligopoly and significantly lower costs for American consumers.
Main Facts
The impending policy change targets the foundational data inputs used by mortgage lenders to assess risk before selling loans to Fannie Mae and Freddie Mac, which together back the vast majority of residential mortgages in the United States.
- The Core Shift: Lenders delivering loans to the GSEs will transition from a "tri-merge" credit report—which aggregates data, scores, and credit histories from all three major credit bureaus (Equifax, Experian, and TransUnion)—to a "bi-merge" report, requiring data from only two of the three bureaus.
- Timeline and Announcement: The directive is slated for announcement by FHFA Director Bill Pulte in mid-October at the MBA conference in Chicago. Implementation is anticipated to occur rapidly, with a projected rollout window of one to three months post-announcement.
- Broader Regulatory Overhaul: This credit reporting shift is part of a broader, aggressive reform agenda spearheaded by Pulte at the FHFA. It closely follows recent decisions to permit the GSEs to utilize credit scores from VantageScore—a tri-bureau joint venture—and to implement a unified pricing grid that treats VantageScore 4.0 as equivalent to Classic FICO scores.
- Cost and Consumer Impact: Proponents argue that eliminating the mandatory three-bureau requirement will disrupt the pricing power of the credit bureau oligopoly, lower origination costs for lenders, and pass those savings down to homebuyers facing high borrowing costs.
Chronology of the Credit Transition
The movement away from the tri-merge standard has been years in the making, evolving from an exploratory policy discussion into an urgent regulatory crusade under current leadership.
The Biden-Era Genesis and Subsequent Delays
The concept of moving from a tri-merge to a bi-merge credit report was first seriously evaluated during the Biden administration under former FHFA Director Sandra Thompson. At the time, the agency recognized that maintaining a mandatory three-bureau mandate imposed unnecessary financial burdens on both lenders and consumers, particularly given that modern risk-assessment models can effectively evaluate credit risk using fewer data streams.
However, the initiative faced substantial operational headwinds. Industry stakeholders, software vendors, and mortgage lenders raised concerns regarding implementation challenges, technological compatibility, and the complex web of legacy underwriting software. Consequently, the transition was delayed indefinitely, leaving the tri-merge requirement intact as industry groups debated the merits of alternative single-file or bi-merge reporting frameworks.
Pulte’s Rapid Acceleration
Following leadership changes at the agency, FHFA Director Bill Pulte swiftly revived and accelerated the credit reporting overhaul. In early September, Pulte signaled the agency’s intentions directly to the public via social media, explicitly calling out the financial dominance of the major credit bureaus.
"Equifax, Experian, and TransUnion have been overcharging Americans for far too long," Pulte wrote on social media. "This will end soon. We are seriously considering bi-merge, and stronger solutions (SAFER and SOUNDER). We will not allow companies to take advantage of American consumers. No more."
This aggressive posture laid the groundwork for the forthcoming October directive. The announcement arrives on the heels of another major policy pivot: the FHFA’s decision to integrate VantageScore 4.0 into GSE operations. Earlier in the week, Pulte announced that Fannie Mae and Freddie Mac would adopt a single pricing grid treating VantageScore 4.0 scores as equivalent to Classic FICO scores. This effectively reversed previous GSE guidelines released just weeks prior, which had assumed VantageScore overstated borrower creditworthiness by roughly 20 points compared to FICO.
Supporting Data and Economic Context
To understand the weight of the FHFA’s decision, one must examine the economics of mortgage credit reporting. For decades, the tri-merge requirement has functioned as an effective tax on every mortgage applicant in America.
The Financial Burden of the Tri-Merge
Under the current system, every time a consumer applies for a mortgage, lenders must purchase credit reports from all three national repositories. Because Equifax, Experian, and TransUnion operate as a tightly entrenched oligopoly, they have faced minimal pricing pressure, steadily increasing the cost of credit reports over time.
For the average borrower, the cost of a tri-merge credit report ranges from $30 to over $100 depending on the region and the lender’s vendor relationships. While this may seem modest in the context of hundreds of thousands of dollars in mortgage debt, these fees accumulate across millions of originations annually, contributing to closing costs that disproportionately impact low- and moderate-income borrowers striving to meet cash-to-close requirements.
Furthermore, industry data indicates that adding a third credit bureau yields marginal improvements in default-prediction accuracy. Risk models developed by the GSEs and independent credit risk analysts demonstrate that two credit files provide sufficient historical data to accurately model consumer credit risk, rendering the third file largely redundant for underwriting purposes.
The Rise of VantageScore and Competitive Pressures
The push for a bi-merge standard cannot be viewed in isolation; it is intrinsically linked to the FHFA’s broader strategy to introduce competition into the credit scoring ecosystem, which has long been dominated by Fair Isaac Corporation (FICO).
By approving VantageScore 4.0 on equal footing with Classic FICO, the FHFA has fractured the traditional credit scoring monopoly. The transition to a bi-merge model further disrupts the status quo by freeing lenders from the obligation to purchase data from all three underlying credit repositories, thereby creating a market mechanism where credit data providers must compete on price and service quality rather than relying on a government-mandated monopoly.
Official Responses and Industry Stakeholder Reactions
Reaction across the housing finance ecosystem has been swift, divided, and reflective of the high stakes involved in reshaping mortgage data standards.
The Mortgage Bankers Association (MBA) and Industry Support
The Mortgage Bankers Association has emerged as one of the most vocal and consistent supporters of moving away from the tri-merge requirement. For years, the MBA has lobbied the FHFA to adopt flexible reporting standards, arguing that a single-file or bi-merge option would modernize the mortgage origination process, reduce overhead costs for independent mortgage bankers, and streamline the technology stack required to process loans.
"The industry has operated under rigid, outdated mandates that enrich data providers at the expense of operational efficiency," noted an industry lobbyist familiar with the MBA’s advocacy efforts. "Moving to a bi-merge framework aligns mortgage underwriting with modern financial technology standards while maintaining robust risk-management safeguards."
Credit Bureaus and Institutional Caution
Conversely, representatives for the major credit bureaus and legacy scoring institutions have expressed caution, warning that rapid changes to underwriting data inputs could introduce short-term operational friction.
Critics of the policy have argued that transitioning to a bi-merge model could lead to fragmentation in how credit scores are interpreted across different lenders, potentially complicating secondary market liquidity if investors perceive inconsistencies in loan file verification. However, FHFA officials have maintained that rigorous testing and the implementation of robust data validation protocols—referenced by Pulte under initiatives dubbed "SAFER" and "SOUNDER"—will ensure that credit quality remains uncompromised.
Note: FHFA officials did not immediately respond to requests for comment from HousingWire regarding the specifics of the upcoming announcement.
Implications for the Mortgage Industry and Consumers
The shift from a tri-merge to a bi-merge credit report carries profound implications for lenders, technology vendors, secondary market investors, and, most importantly, American homebuyers.
1. Cost Reductions for Borrowers
The most immediate and tangible benefit of the bi-merge transition will be a reduction in upfront closing costs for mortgage applicants. By cutting out the cost of one credit bureau report per loan, lenders can trim administrative expenses. While lenders will determine how these savings are passed along, increased competitive pressure is expected to drive down fees across the board.
2. Technological and Operational Adjustments for Lenders
Mortgage lenders, loan origination system (LOS) vendors, and credit reporting agencies face a compressed timeline to update their software platforms. Shifting from a three-file requirement to a two-file standard requires adjustments to automated underwriting systems (AUS), pricing engines, and compliance documentation. Lenders operating on legacy systems will need to move quickly to ensure their pipelines are compliant within the projected one-to-three-month implementation window following Director Pulte’s expected announcement.
3. Increased Competition in Credit Data
By enabling lenders to choose which two credit bureaus to pull data from, the FHFA is introducing real market competition to Equifax, Experian, and TransUnion. If a specific bureau charges excessive fees or experiences chronic service disruptions, lenders can bypass them entirely—a dynamic that was impossible under the mandatory tri-merge regime.
4. Evolution of Secondary Market Risk Management
For Fannie Mae and Freddie Mac, the GSEs will need to ensure that their risk-adjustment models accurately price loans under the bi-merge standard. However, extensive analytical modeling conducted during the Biden administration’s initial review indicated that transitioning to two credit files does not materially degrade the predictive power of credit evaluations. Consequently, secondary market investors should experience minimal disruption to mortgage-backed security (MBS) performance.
Conclusion
As the mortgage industry prepares for the Mortgage Bankers Association conference in Chicago on October 12, all eyes are turned toward FHFA Director Bill Pulte and the anticipated announcement of the bi-merge credit reporting mandate.
By dismantling the mandatory tri-merge requirement, the FHFA is poised to deliver a structural blow to the entrenched credit bureau oligopoly, lower closing costs for consumers, and modernize the technological architecture of American mortgage underwriting. While implementation challenges remain, the decisive momentum behind the initiative signals that the era of mandatory three-bureau credit reporting is drawing to a close.
