Credit decisions can open or close important financial doors. Whether a person is applying for a credit card, auto loan, mortgage, or business financing, the information used to assess repayment risk influences approval, loan size, pricing, and the speed of the decision. Industry conversations, including those associated with Kirk Chewning Cane Bay Partners, often reflect a broader need for lenders to balance access, accuracy, consumer protections, and responsible risk management.
Better lending does not mean gathering every possible data point. It means using relevant, reliable information, testing how decisions affect applicants, and giving people understandable reasons when credit is denied or limited. In 2026, lenders have more tools than ever, but fair outcomes still depend on careful governance and meaningful human judgment.
Why Credit Data Still Shapes Access
Lenders use credit data to estimate the likelihood that an applicant will repay as agreed. Payment history, debt levels, account age, income verification, and cash-flow information can each contribute to that estimate. The result may affect not only whether an application is approved, but also the interest rate, credit limit, collateral requirement, and whether a manual review is needed.
A credit file is useful, but it is not a complete biography of someone’s financial capacity. Consider an applicant with stable employment and consistent savings who has only recently begun using credit. A traditional score may show limited history, while verified income and responsibly managed recurring expenses could provide important additional context.
Where Traditional Credit Files Fall Short
Traditional files can be incomplete, especially for young adults, recent arrivals, people who prefer debit-based spending, and entrepreneurs whose finances do not fit a standard payroll pattern. Information may also be stale, duplicated, or inaccurate after a dispute. For small-business owners, personal and business obligations may overlap in ways that make repayment capacity harder to interpret.
These gaps matter because access remains uneven. In 2025, one-third of people who applied for credit reported being denied or receiving less credit than requested, while reported outcomes differed substantially across racial and ethnic groups, according to the Federal Reserve’s credit outcomes research. That does not mean every difference has one cause, but it does make consistent monitoring essential.
How Alternative Data May Help
Alternative data is information outside the conventional credit-reporting record that may help show a borrower’s ability or willingness to repay. When used with permission and appropriate safeguards, it can provide a more current view of financial behavior.
- Cash-flow patterns from a permissioned bank account.
- Rent, utility, or insurance payment history.
- Verified employment and income information.
- Business cash receipts, invoice activity, and operating expenses.
- Recurring payment behavior and account-balance stability.
Alternative data should supplement sound underwriting, not replace it. A one-time account balance or a single late utility payment rarely tells the full story. Lenders should consider whether the data is accurate, current, relevant to repayment risk, and reasonably available for a consumer to review or challenge.
The Fairness Risks Of More Data
A larger data set can create new problems when inputs are poorly chosen. Certain variables may serve as proxies for protected characteristics or neighborhood conditions. A model may also inherit unfair patterns from historical decisions, especially if it was trained on past approvals and denials without examining whether those earlier outcomes reflected bias or unequal access.
Every data point should have a clear underwriting purpose, a reliable source, and a documented reason for inclusion. Lenders should avoid relying on opaque information that consumers cannot understand or dispute. Automated systems can improve consistency, but they should not eliminate meaningful oversight for unusual applications, disputed records, or outcomes that appear inconsistent with policy.
How To Test A Credit Model
Build Review Into The Model Lifecycle
- Define the goal. Specify what the model predicts and what decisions require a separate policy review.
- Review the inputs. Confirm where each variable comes from, how often it is refreshed, and whether it is reliable.
- Measure accuracy. Compare predicted repayment outcomes with actual performance over time.
- Check group results. Review approval, denial, pricing, exceptions, and errors across relevant applicant groups.
- Test edge cases. Examine thin-file applicants, seasonal earners, irregular income, and unusual account patterns.
- Document changes. Record who approved each update, why it was made, and how it was validated.
- Monitor after launch. Reassess results as economic conditions, products, and applicant behavior change.
Why Clear Explanations Matter
A useful adverse-action explanation identifies the meaningful reasons behind a decision in language a person can understand. Vague statements such as “internal score” offer little help to consumers or frontline staff. A specific explanation, such as insufficient verified income relative to current obligations, gives the applicant a clearer opportunity to correct an error or improve a future application.
Explainability should be designed before a model goes live. Lenders need a defensible connection between the information used in a decision and the reasons communicated to the applicant. This also helps compliance, complaint handling, quality control, and internal training.
Special Considerations For Small-Business Lending
Small-business lending requires added context because revenue may be seasonal, operating history may be short, and expenses can change quickly. Lenders should separate personal and business risk where possible, review cash flow across several periods, and use consistent definitions for revenue, debt, and repayment capacity.
Reliable records are equally important. The CFPB’s small-business lending rulemaking states that the revised Regulation B framework includes a January 1, 2028, compliance date. Lenders can use the lead time to strengthen application records, pricing documentation, data-quality checks, and fair-lending controls.
A Practical Action Plan
- List every data source used in credit decisions.
- Remove inputs without a clear underwriting purpose.
- Check for missing values, stale records, and repeated errors.
- Run fairness tests before and after major model updates.
- Set a recurring schedule for independent model review.
- Create an escalation process for unusual or disputed decisions.
- Keep disclosures and explanations of decisions easy to locate.
- Train staff on privacy, documentation, fair lending, and complaint handling.
Final Thoughts
Better credit decisions do not come from collecting the most data. They come from using relevant information with care. Lenders that combine accurate records, responsible analytics, regular testing, human review, and clear explanations can expand access while managing risk. Fairness is not a one-time model approval. It is an ongoing process of measurement, accountability, and improvement.
