In recent years, with the continuous improvement of the financial system and the rapid development of the banking industry, the competition of the banking industry itself has intensified. At the same time, with the rapid development of information technology and Internet technology, customers’ choice of financial products is becoming more and more diversified, and customers’ dependence and loyalty to banking institutions is becoming less and less, and the problem of customer churn in commercial banks is becoming more and more prominent. How to predict customer behavior and retain existing customers has become a major challenge for banks to solve. Therefore, this study takes a bank’s business data on Kaggle platform as the research object, uses multiple sampling methods to compare the data for balancing, constructs a bank customer churn prediction model for churn identification by GA-XGBoost, and conducts interpretability analysis on the GA-XGBoost model to provide decision support and suggestions for the banking industry to prevent customer churn. The results show that: (1) The applied SMOTEENN is more effective than SMOTE and ADASYN in dealing with the imbalance of banking data. (2) The F1 and AUC values of the model improved and optimized by XGBoost using genetic algorithm can reach 90% and 99%, respectively, which are optimal compared to other six machine learning models. The GA-XGBoost classifier was identified as the best solution for the customer churn problem. (3) Using Shapley values, we explain how each feature affects the model results, and analyze the features that have a high impact on the model prediction, such as the total number of transactions in the past year, the amount of transactions in the past year, the number of products owned by customers, and the total sales balance. The contribution of this paper is mainly in two aspects: (1) this study can provide useful information from the black box model based on the accurate identification of churned customers, which can provide reference for commercial banks to improve their service quality and retain customers; (2) it can provide reference for customer churn early warning models of other related industries, which can help the banking industry to maintain customer stability, maintain market position and reduce corporate losses.

Retail Bank Loyalty Program Market Outlook

The global market size for retail bank loyalty programs is poised for significant growth, projected to expand from $3.5 billion in 2023 to $7.8 billion by 2032, reflecting a compound annual growth rate (CAGR) of 8.9%. This growth is driven by increasing competition among retail banks to attract and retain customers through personalized and rewarding loyalty programs. The desire to enhance customer engagement and build long-term relationships is propelling the market, with technological advancements further enabling sophisticated and individualized loyalty solutions.

A major growth factor in the retail bank loyalty program market is the increasing emphasis on customer retention. Banks are recognizing that it is more cost-effective to retain existing customers than to acquire new ones. Loyalty programs, which offer rewards and incentives, have proven effective in maintaining customer loyalty and reducing churn. Moreover, the data analytics capabilities now available to banks allow them to tailor loyalty programs more precisely to individual customer preferences, thereby enhancing customer satisfaction and loyalty.

Another key driver is the evolution of digital banking and mobile financial services. With the proliferation of smartphones and rising internet penetration, there is a significant shift towards digital channels. This trend has made it easier for banks to implement and manage loyalty programs online and through mobile applications. Digital platforms facilitate real-time engagement with customers, making loyalty programs more dynamic and responsive to customer behavior. This digital transformation is critical in catering to tech-savvy customers who expect seamless and instant gratification from their banking experiences.

The integration of advanced technologies such as artificial intelligence (AI) and machine learning (ML) is also augmenting the growth of retail bank loyalty programs. These technologies enable banks to analyze large volumes of customer data and derive actionable insights. AI and ML can predict customer behavior, personalize rewards, and enhance overall program effectiveness. Additionally, blockchain technology is being explored to ensure transparency and security in loyalty transactions, further boosting customer trust and program credibility.

Loyalty Program strategies are becoming increasingly sophisticated, leveraging data analytics to enhance customer experiences. By analyzing customer behavior and preferences, banks can design loyalty programs that offer personalized rewards, fostering deeper engagement and satisfaction. This approach not only helps in retaining existing customers but also attracts new ones by showcasing the bank's commitment to understanding and meeting individual needs. As banks continue to innovate their loyalty offerings, the integration of AI and machine learning further refines these programs, making them more responsive and dynamic. Such advancements ensure that loyalty programs remain relevant and appealing in a competitive market landscape.

Regionally, North America holds a significant share of the market, driven by the high adoption rate of advanced banking technologies and the presence of major financial institutions committed to innovative loyalty programs. Europe follows closely, with a focus on regulatory compliance and customer-centric banking services. The Asia Pacific region is expected to witness the highest growth rate due to the rapidly increasing digital banking penetration and the expansive middle-class population. Latin America and the Middle East & Africa are also showing promising growth, albeit at a slower pace, as they continue to develop their banking infrastructure and adapt to global digital trends.

Program Type Analysis

Point-based loyalty programs are a cornerstone in the retail banking sector. These programs allow customers to earn points for various banking activities, such as transactions, savings, and even referrals. Customers can then redeem these points for rewards, which may include merchandise, discounts, or even cash. The simplicity and flexibility of point-based programs make them highly popular among customers and effective for banks. They encourage regular interaction with banking services, thereby increasing customer engagement and satisfaction. Additionally, point-based programs are easy to manage and integrate with existing banking systems.
