Fannie Mae and lenders are shifting to newer credit scoring models that consider rent, utilities, and other alternative payment history to evaluate borrowers more fairly.
FHFA says mortgage lenders can use VantageScore 4.0 from April 22, 2026, and FICO 10T is expected later in 2026. The models add rent, utilities, and telecom payment history and use 24-month trended data. Fannie Mae and Freddie Mac began accepting VantageScore 4.0.

How this was made
The 30-second read
Why it matters
The key trading relevance is underwriting and credit-risk model transition timing for the GSEs and their counterpart lenders, with potential downstream effects on mortgage origination mix and risk metrics.
Market read
This is a US mortgage underwriting infrastructure change that can affect borrower eligibility and credit-risk calibration, but the article lacks new performance results for the GSEs themselves.
What to watch
Actual performance depends on how lenders operationalize the scores (cutoffs, overlays, fraud controls) and whether BNPL and medical-debt reporting changes offset or amplify eligibility shifts.
Background
FHFA validated VantageScore 4.0 and FICO 10T in 2022 and is implementing them in phases; VantageScore 4.0 uses alternative payment data and trended 24-month patterns.
Ticker impact
Article says Fannie Mae began accepting VantageScore 4.0 scores immediately starting April 22, 2026, changing mortgage credit evaluation inputs.
Likely modest, indirect impact unless underwriting performance data diverges materially from prior models.
The article describes model adoption timing and scope (rent/utilities/telecom, trended data) but provides no performance results, guidance, or balance-sheet impact figures for Fannie Mae.
Article states Freddie Mac also began accepting VantageScore 4.0 scores right away, aligning GSE credit scoring inputs across most mortgages.
Near-term price effect likely limited; watch for later evidence on default/repurchase rates under the new scoring regime.
The text focuses on regulatory validation and phased rollout, not on observed credit outcomes or any GSE-specific financial metrics.
Market effects
Credit scoring model changes can affect mortgage origination volumes, underwriting standards, and default-risk calibration across lenders and mortgage insurers.
Primarily US mortgage market impact via GSE underwriting acceptance and lender adoption timelines.
Limited direct global effect, but could influence US mortgage credit risk assumptions used by global investors in MBS.
Counterpoint
Model adoption does not automatically change credit outcomes; lenders may already approximate alternative-data signals, so the incremental risk impact could be small.
