Fair Isaac Stock Plunges 14% as US Regulators End FICO's Mortgage Monopoly

(P1) A decision by U.S. housing regulators to allow alternative credit scores for mortgages shattered Fair Isaac Corp.’s long-standing monopoly, sending its stock down as much as 14 percent and signaling a new era of competition in the housing finance market. The move allows lenders to use scores from FICO competitor VantageScore for loans backed by Fannie Mae and Freddie Mac.

(P2) "Effective immediately, we will allow mortgage lenders to use VantageScore when making lending decisions," Federal Housing Finance Agency (FHFA) Director Bill Pulte said at a press conference, a move he described as a "historic announcement" that will modernize the mortgage industry.

(P3) The market reaction was immediate and severe. Fair Isaac (FICO) shares plunged, reflecting fears of a dramatic shift in its lucrative business model. The announcement also triggered a price war, with Pulte noting that VantageScore prices its model at 99 cents per borrower, prompting FICO’s CEO to call and offer to slash its own price from around $10 to match the 99-cent fee. Shares of VantageScore's owners, Equifax and TransUnion, also fell 7.4 percent and 4.7 percent respectively.

(P4) At stake is the way millions of Americans qualify for a mortgage. By incorporating alternative data like rent and utility payments, the new system aims to provide a credit score for borrowers with limited traditional credit history. VantageScore estimates the shift could make an additional 4.9 million people eligible for a mortgage, potentially expanding access to homeownership at a time of elevated borrowing costs.

A New Playbook for Borrowers

The policy change ushers in two new credit-scoring models: VantageScore 4.0 and FICO’s own newer FICO 10T. Unlike the older snapshot models that have dominated for years, both systems incorporate "trended data," analyzing a person's payment and debt trends over a 24-month period. This means positive financial habits, like consistently paying down debt, will now be more visible and rewarded.

"Consistent habits over time matter more than ever," said Kimber White, president of the National Association of Mortgage Brokers. While the core advice of paying bills on time and keeping balances low remains, the inclusion of timely rent and utility payments offers a new pathway to building credit for prospective homebuyers. According to VantageScore's chief economist, Rikard Bandebo, reporting on-time rent payments could boost some scores by as much as 100 points.

A Reality Check on Affordability

Despite the significance of the regulatory shift, some experts caution that it is not a silver bullet for the nation's housing affordability crisis. John Ulzheimer, a credit expert formerly at Equifax and FICO, noted that while the changes require a longer preparation horizon for obsessive score-maximizers, "someone who has a killer credit score is still going to have a killer credit score."

The primary challenge for most aspiring homeowners remains the cost of housing itself, not their credit score. "Obviously, the real issue in this country with the homeownership rate isn't the credit score—it's that housing prices are so damn high," Chi Chi Wu, a consumer law advocate, told MarketWatch. While the new models may help a small segment of borrowers at the margins, they don't address the fundamental supply and demand imbalances pushing prices to record levels.
