About our client
A US-based regional bank with $145B in assets and a network of 800 branches across eight states. Serving 3M+ customers, the bank manages an $85B loan portfolio spanning mortgages, commercial lending, and consumer credit. Rising defaults and slow approvals were starting to erode competitiveness.
Industry
Objective
The bank set out to modernize credit risk assessment to improve prediction accuracy and speed up decisions—without compromising compliance. This meant deploying ML-driven scoring, automated underwriting for low-risk applications, and robust explainability/fairness controls to build ML credit models across key products with richer signals, automate low-risk underwriting to accelerate decisioning, ensure fair lending compliance with transparent reason codes, and reduce charge-offs while elevating customer experience.
The challenge
Legacy scorecards, limited data use, and weak explainability held models back from production. Manual underwriting created bottlenecks, while disparate impact risks blocked deployment.
- Traditional scorecards: Missed 46% of SME defaults with outdated risk factors
- Manual processing: Underwriting averaged 7 days per decision creating customer friction
- Limited data usage: Alternative data unused in 73% of credit decisions
- Fairness failures: Prior ML attempts showed 41% disparate impact failing fairness tests
- Explainability gaps: 68% of models lacked transparency required for production
- Rising losses: Default losses hit $47M/year, 35% over risk appetite
Standard credit modeling tools couldn't balance accuracy with regulatory requirements. The bank needed sophisticated ML approaches that maintained transparency and fairness while significantly improving prediction power.
