Don’t Let Credit Scoring Reform Put Taxpayers at Risk

The Great Financial Crisis of 2008 provided a case study on the way in which government manipulation and forced suppression of credit standards can result in unintended negative consequences not just for lenders and borrowers, but also the broader economy. At a time when the housing market is already under pressure, changes to how mortgage credit is evaluated should be approached with care. That’s why the current conversation around credit scoring reform deserves a more measured approach.

At the center of this debate is a proposed shift in how mortgage creditworthiness is evaluated. Today, mortgage underwriting largely relies on established models. However, federal regulators are now considering changes that would allow lenders to use multiple credit scoring models when issuing mortgages backed by Fannie Mae and Freddie Mac. In that mix is VantageScore, a scoring model that is jointly owned by all three credit bureaus themselves. While intended to introduce more flexibility, this change raises important questions about how risk is measured and whether underwriting standards will remain consistent.

This isn’t just a policy debate, as it affects Nashvillians and folks across Tennessee who are trying to buy a home, the lenders working with them, and taxpayers who ultimately support the system. Earlier this year, Americans for Tax Reform (ATR) and 34 other groups sent a joint letter urging the FHFA to proceed carefully with any changes to credit score rules. This is an area where Congress should exercise its oversight authority to demand answers on how this change, initially pushed under the Biden administration, was made by the FHFA Director Pulte. Notably, Pulte made that change against the recommendation of Fannie Mae and Freddie Mac.

Among the concerns about Pulte’s decision is its precipitation of market uncertainty, particularly if changes to credit scoring affect how risk is assessed across the system. Because taxpayers ultimately stand behind the mortgage market through federally backed entities, even small shifts in underwriting can carry real financial implications and put taxpayers at unnecessary risk.

That is why the path forward matters just as much as the policy itself. Changes to a system as foundational as mortgage underwriting should be introduced with a clear understanding of how they will function across different market conditions—not just in theory, but in practice.

When the people and institutions relying on the mortgage underwriting system don’t have visibility into how decisions are made or what data supports them, it becomes harder to evaluate tradeoffs and anticipate unintended consequences. In a network that affects homebuyers, lenders, and investors alike, that kind of uncertainty can ripple outward quickly.

None of this is to suggest that the system should remain static. Credit scoring can and should evolve over time, particularly if new approaches can improve accuracy or expand responsible access to credit. But reform should be approached with discipline—grounded in evidence, implemented thoughtfully, and communicated clearly to those it affects.

Tennessee has great leaders in Senator Bill Hagerty, Congressman John Rose and Congressman Andy Ogles, who all sit on the relevant committees with oversight on this issue. Congress should indeed exert its authority to look into housing finance changes made unilaterally by FHFA. The Great Financial Crisis showed us what can happen when the government undermines credit standards in a sector as important as housing. Hopefully we won’t have to learn that lesson the hard way again.
