Customer Experience: Community banks and credit unions often differentiate themselves through personalized service. Advanced credit decisioning models can enhance this differentiation by providing deeper insights into customers' financial behaviors, leading to a more tailored offering

Community Development: With more accurate and inclusive credit decisioning, these institutions can better serve their communities by extending credit to underserved populations. This can drive economic growth and financial inclusion at the local level

Why Advanced Credit Decisioning Models are Business-Critical

Advanced credit decisioning models are a linchpin for community banks and regional credit unions striving to maintain a competitive edge, meet regulatory demands, and provide exceptional service to their communities.

Competitive Edge: Traditional credit scoring models may not be able to accurately evaluate the creditworthiness of certain customers, particularly those with thin credit files or non-traditional credit histories. Advanced credit decisioning models can incorporate a broader range of data, enabling these institutions to more accurately evaluate such customers and potentially expand their customer base (See: Journal of Consumer Affairs, 2021). Moreover, by providing quicker, more accurate credit decisions, these institutions can significantly enhance their operational efficiency and profitability.

Regulatory Compliance: With increased scrutiny from regulatory bodies to prevent discriminatory lending practices and ensure fair credit opportunities for all customers, advanced models are crucial. By incorporating variables such as employment stability, rental history, and utility payment history, these models can ensure a more comprehensive and fair evaluation of creditworthiness while remaining compliant with relevant regulation

Customer Retention: Community banks and credit unions often compete with larger financial institutions by providing superior, personalized customer service. Advanced credit decisioning models can enhance this service by providing deeper insights into customers' financial behavior, leading to more tailored product offerings and ultimately improving customer satisfaction and retention

Effective Risk Management: Effective risk management is critical for community banks and credit unions, as they often have lower risk tolerance than their larger counterparts. Advanced credit decisioning models allow for improved risk segmentation, enabling these institutions to extend credit more responsibly and mitigate the potential for significant credit losses

Local Economic Development: Community banks and credit unions are central to their local economies. Advanced credit decisioning models can improve their ability to extend credit to underserved segments of their communities, fostering local economic growth and enhancing financial inclusion

Best Practices for Implementation

Modular Implementation Approach: While a singular optimization algorithm run over a consolidated database theoretically delivers an optimal model, industry leaders favor a modular architecture. This incorporates multiple sub-models based on data coverage, industry and geographic variations. These modules, which are combined to yield a single, overarching credit signal, can be easily added or removed, allowing for the integration of new or differing data. Consequently, the model remains flexible and robust. Implementing this architecture requires coordination among stakeholders including the business, model development team, and model maintenance team.

Explore Data Sources: Top performers utilize a blend of internal and external data sources to bolster the predictive power of credit signals. Traditional internal data is combined with non-traditional data and enriched with traditional external data. Other external non-traditional data sources are also explored, including subjective data from Relationship Managers and underwriters to fill gaps. Open banking and non-traditional external data such as telecom and social media data can provide valuable insights into customer behaviors.

Data Mining: Industry leaders excel at mining existing data and combining data sources to extract highly predictive credit signals. They leverage machine learning (ML) and artificial intelligence (AI) to form a more complete, albeit slightly imprecise, view of the customers. Advanced banks leverage deep analytics and apply ML and AI in areas such as creating segmentation rules, deriving credit signals, and building and validating challenger models.

Business Expertise: While ML and AI are powerful tools, they should not be the sole basis of credit models. Banks should leverage internal business expertise during the model development process to better understand where credit signals are missing, and then identify and validate new credit signals. Model designers should consult with underwriters and Relationship Managers to translate their insights into qualitative questions for better credit signaling.

Adhering to these best practices can help banks successfully implement advanced credit decisioning models, enabling them to make more accurate and informed credit decisions, respond swiftly to economic disruptions, uncover new growth areas, and maintain a competitive edge in the marketplace.

A Step-by-Step Approach for Implementation

Adopting a five-stage agile process can expedite the implementation of a new credit decisioning model within six months, a stark improvement from the standard industry timeline of 12 to 24 months. The following steps outline this transformative approach:

Credit Model Review: Begin by conducting a comprehensive analysis of the existing credit model. This includes a review of its methodological setup, performance, and application within the business context to pinpoint potential areas for enhancement.

Credit Model Design: Evaluate the current state of data readiness, identifying easy-to-integrate data sources. Following this assessment, devise a roadmap for data inclusion into the model. To identify areas of weakness, carry out a comparative performance evaluation of the model across various segments and against industry peers.

Data Inventory and Assessment: Once the needs are defined, the next step is to take stock of the data available. This includes assessing the quality, relevance, and accessibility of the data. Data gaps need to be identified, and plans should be made to fill these gaps, possibly through partnerships with data providers or by developing new data collection methods. It's also necessary to ensure proper data governance protocols are in place to maintain data integrity and privacy.

Data Preparation and Engineering: This stage involves readying the data for modeling. It includes data formatting, completeness testing, and the handling of missing values and record treatment. These steps ensure the data are in a state conducive to the subsequent modeling processes.

Development of Credit Scoring Models: Develop a production-ready minimal viable product (MVP) for the next-generation credit decisioning model. This stage typically includes three two-week cycles of modeling, incorporating feedback from experts and data analysis in each iteration to enhance the model's efficacy.

Integration of Credit Scoring in Lending Transformation: The final stage involves automating lending processes and updating the credit decisioning model with the newly developed credit scoring models. This step effectively integrates the new advanced models into the lending decision-making process, thereby enhancing the overall efficiency and accuracy of credit decisions.
