KBRA Releases Research ? VantageScore 4.0 Adoption?RMBS Credit Paradigm Shift?

BY Business Wire | AGENCY | 07/09/25 06:32 PM EDT

NEW YORK--(BUSINESS WIRE)-- KBRA releases research commenting on the Federal Housing Finance Agency's (FHFA) July 8 announcement that lenders may now use VantageScore 4.0 (VS4) for mortgages sold to government-sponsored entities (GSE) Fannie Mae and Freddie Mac.

In the report, KBRA revisits its July 2024 research on the historical loan-level VantageScore 4.0 data released by the GSEs, highlighting key considerations for mortgage market participants as the new model becomes available for underwriting and delivery.

The commentary includes the following key takeaways:

  • Score Mapping: While both models share a 300-850 scale, VantageScore 4.0 systematically scores borrowers higher than classic FICO, particularly in the mid-score ranges (e.g., 625-750).
  • Inclusivity: VS4 expands the scorable population by leveraging data and algorithms that allow it to score consumers with less than six months of credit history.
  • Predictive Power: For rank-ordering borrower credit risk?particularly for loans that became nonperforming?VS4 and classic FICO both performed effectively, with slight advantages in granularity observed in VS4 for lower-score borrowers.

KBRA will continue to monitor the implementation of VantageScore 4.0 and provide updates as additional guidance becomes available.

In general the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation risk and credit and default risks for both issuers and counterparties. Unlike individual bonds, most bond funds do not have a maturity date, so avoiding losses caused by price volatility by holding them until maturity is not possible.

Lower-quality debt securities generally offer higher yields, but also involve greater risk of default or price changes due to potential changes in the credit quality of the issuer. Any fixed income security sold or redeemed prior to maturity may be subject to loss.
