🛟 Need to Know: AI & Fair Credit in a Deregulated Era

In January 2025, Executive Order 14192, Unleashing Prosperity Through Deregulation, required federal agencies to repeal at least ten existing rules for every new one introduced.

As a direct result, the Consumer Financial Protection Bureau (CFPB) was ordered to halt all supervision, examination, and enforcement activities related to consumer lending.

This has eliminated centralized federal oversight of credit decisioning. In its place, a patchwork of state-level regulation is rapidly emerging. Some states are introducing AI-specific laws governing automated lending decisions, while others have deferred entirely. This is creating jurisdictional inconsistencies that materially increase compliance complexity for national banks.

For example, California has introduced draft legislation requiring transparency reports and bias impact assessments for AI models used in credit decisioning. New York is advancing proposals that would classify automated lending models and insurance as "high-risk" systems, mandating external audit requirements. Other states, such as Texas and Florida, have taken a more hands-off approach, reinforcing the fragmented risk environment.

Read more about the emerging patchwork of state-level regulation in last week’s issue of AI Check In.

Without a federal baseline, the burden of governance now falls squarely on internal frameworks. Boards must take direct ownership of model lifecycle oversight, legal exposure monitoring, and reputation-sensitive decisions about AI use in credit underwriting. The regulatory vacuum does not reduce risk. It does however redistribute it across a more fragmented and politically variable landscape.

Boardroom Implications

• Market Response: Many institutions are shifting from risk-averse compliance builds toward AI-enabled credit expansion strategies under deregulation.

• Governance Load: Responsibility for AI governance, including retraining cadence, documentation, fairness audit policy and critical vendor dependency risk, now rests fully with the board and executive team.

• State Pressure and Stakeholders: Legal and reputational risk has shifted to the state level. Proactive engagement with regulators, industry groups, and consumer advocates is now a strategic necessity to pre-empt scrutiny and shape expectations.

🥊 Your Move

• Mandate State Risk Tracking: Require a live compliance dashboard or watchlist identifying key AI-relevant legislative activity across top exposure states.

• Reinforce Internal Governance: Establish a board-level AI risk review cycle with audit trails, retraining protocols, and accountability for credit model deployment.

• Engage to Influence: Build structured relationships with key state regulators and advocacy groups to monitor sentiment, flag early concerns, and shape policy before it hardens.

🥷 Deep Dive: AI-Driven Credit Scoring in U.S. Banking

Strategic Context

AI-driven credit scoring is now a core engine for loan growth, operational efficiency, and real-time risk management. In a deregulated environment, execution quality, not compliance alignment, is becoming the primary differentiator. Institutions that formalize AI oversight and governance within their credit scoring systems are already seeing measurable performance gains.

Execution and Outcomes - In-Field Highlights

Golden 1 Credit Union

• Deployment: Custom AI scorecard using Zest AI.

• Outcome: +28% loan approvals for protected class applicants, including women, Latinx, Black, and senior borrowers.

JPMorgan Chase

• Deployment: Machine learning model using 82 borrower-specific variables.

• Outcome: 40% faster loan decisions, 20% reduction in subprime defaults, 15% operational cost savings.

HSBC USA

• Deployment: NLP-based automation for parsing SEC filings and borrower financials.

• Outcome: 28% improvement in early risk detection, $150M in annual savings.

Suncoast Credit Union & First Hawaiian Bank

• Deployment: End-to-end lending automation with Zest AI.

• Outcome: 10x increase in automation, reduced manual processing load.

Model Governance: Lifecycle Accountability

As regulatory authority decentralizes, boards are being pulled closer to operational oversight. Leading institutions are aligning with supervisory guidance on model risk such as OCC SR 11-7 by implementing full-lifecycle AI governance structures:

1. Champion–Challenger Testing: Quarterly head-to-head model validation to detect degradation or overfitting.

2. Retraining Protocols: Different to finetuning, this involves monthly refresh cycles using updated repayment data and borrower behavior.

3. Internal Audit Trails: Documented input variables, decision logic, and version histories for model transparency.

Boards are expected to verify that these controls are not just in place—but enforced, reviewed, and aligned with emerging state-level AI expectations.

Risk Management Innovations

1. Dynamic Credit Limits: Credit terms updated in real time based on income volatility, job changes, or macroeconomic triggers.

2. Bias Mitigation: Systematic detection and correction of discriminatory scoring outcomes via debiased datasets.

3. Explainability Frameworks: Use of LIME, SHAP, or equivalent to support transparent decision-making under scrutiny.

Strategic ROI Metrics

These metrics reflect what high-performing banks are achieving with operationalized AI governance:

🥊 Your Move

• Mandate Full Lifecycle Reviews: Establish quarterly board oversight of AI credit models, including retraining cadence, performance benchmarking, and challenger testing.

• Integrate ROI into Reporting: Track approval rates, default outcomes, and cost savings across AI-assisted portfolios—and report findings at the executive level.

• Audit Explainability Systems: Confirm that model decisions are transparent, traceable, and defensible in the face of legal or regulatory scrutiny.

⚔️ Instruments of Mastery:  Zest AI in U.S. Credit Underwriting

Credit unions and regional banks are using Zest AI to automate underwriting, expand credit access, and strengthen fairness controls.

Golden 1 Credit Union leveraged Zest AI’s configurable underwriting models to better identify creditworthy applicants across diverse borrower segments, driving a measurable expansion in inclusive lending.

First Hawaiian Bank and Suncoast Credit Union reported 10x increases in automation, sharply reducing manual loan processing while improving model precision.

Zest’s explainability tools and bias mitigation modules support consistent decisioning and transparent audit trails—critical in a state-led regulatory environment.

Institutions deploying Zest’s retrained models have also reported material gains in predictive accuracy (+34%), strengthening portfolio resilience without compromising risk thresholds.

As reliance on AI vendors increases, boards must also evaluate vendor governance practices—specifically, the transparency of model development processes, the robustness of audit documentation, and the institution's contractual rights to conduct independent assessments.

Board takeaway: A 10x increase in lending automation enables faster credit delivery, reduced operating costs, and scalable loan growth without expanding headcount.

Tools that enable 10x automation gains must also be evaluated for governance resilience. Bias mitigation, decision explainability, and audit trail generation are now baseline requirements for scalable AI deployment.

🥊 Your Move:

• Audit Lending Automation: Identify manual decision points where AI-based underwriting could accelerate approvals without compromising governance standards.

• Require Auditability: When evaluating AI tools, mandate built-in documentation of decision pathways, model inputs, and retraining logs.

• Benchmark Fairness Controls: Ensure any new underwriting platform includes real-time bias detection, reporting, and mitigation features as part of standard operations.

📈 Trends to Watch: The Growing Gap in AI Credit Strategy

The widening gap between adaptive and stagnant lenders is now reshaping future market leadership in AI-driven credit. As regulatory oversight recedes, competitive positioning is no longer determined by compliance readiness—but by the ability to operationalize transparency, flexibility, and speed at scale.

Leaders

• Real-Time Risk Monitoring: Continuously adjust borrower credit limits based on transaction patterns and financial signals.

• Flexible SME Lending: Offer revenue-based repayment structures and dynamic credit terms to small businesses. Note: transaction platforms, such as Paypal and Square, are actively moving into this space.

• Transparency Standards: Maintain bias audits and explainable AI decision frameworks despite lower regulatory pressure locally. Watch international jurisdictions for compliance arbitrage.

Laggards

• Static Risk Management: Rely on annual credit reviews and rigid scorecard updates. Longer lead times, higher costs, less accurate than leaders.

• Fixed-Term SME Lending: Apply legacy underwriting criteria with inflexible loan terms.

• Transparency Gap: Scale back fairness and bias detection efforts, increasing litigation and reputational risk.

Institutions that lag in deploying adaptive AI credit models risk exclusion from emerging borrower segments and exposure to widening reputational gaps as transparency expectations grow.

The global credit scoring market is projected to reach $46.22 billion by 2034, with AI-driven models playing a significant role in this growth. Making informed governance and technology choices today is crucial for long-term competitive resilience.

🥊 Your Move

Boards and executive teams that fail to adapt to evolving transparency, fairness, and governance expectations risk breaching their fiduciary duties as scrutiny around AI-enabled credit decisioning accelerates.

• Benchmark Aggressively: Compare your AI credit strategies, approval dynamics, and transparency protocols against top-performing institutions quarterly.

• Audit Flexibility Gaps: Identify rigid lending products that could be restructured using adaptive AI models for dynamic risk and repayment.

• Pressure-Test Credit Models: Simulate borrower volatility scenarios to assess whether models can dynamically adjust without manual intervention.

🔮 Next Week

Institutions operating across U.S. and European markets face a growing risk of strategic misalignment: prioritizing the wrong compliance standard could create costly operational blind spots.

Next week, we’ll look at MiFID II vs. U.S. Deregulation and consider where AI compliance efforts should be prioritized? We’ll break down how the shifting regulatory landscape is forcing banks to reassess whether European frameworks still matter, or if growth-focused models can now take the lead.
