1) Customer Relationship Management

Customer relationship management is one of the significant data science applications in banking. Let’s understand its criticality. Any organization’s success greatly depends on its customers; therefore, it is no surprise that most organizations, including banks, emphasize customer satisfaction.

To enhance customer satisfaction, one has to manage them efficiently. To do so, organizations must deeply understand their customer base, find their value, identify the ones they risk losing, offer them services, etc. In all these aspects of customer relationship management, data science plays a critical role. 

a. Churn Prediction

A key application of data science in banking is predicting customer churn. Banks use AI-powered models to identify customers at risk of leaving, whether by closing accounts, canceling credit cards, or reducing interactions, such as transferring funds or removing overdrafts.

To assess churn risk, these models analyze customer behavior data, including payment history, transaction types, account balances, and more. Once a customer is flagged as a potential churn risk, banks can take action to retain them, offering incentives like lower fees, reduced interest rates, or debt restructuring to address specific concerns.

b. Lifetime Value Prediction

Another aspect of customer relationship management is assessing the customer’s lifetime value, which can help banks focus on high-value customers. By using AI and data science in banking and finance, organizations can determine a customer’s value and optimize their marketing strategies to maximize their customer base.

AI-powered predictive algorithms can look into historical customer behavior, spending patterns, and demographic information such as gender, age, income level, and employment type to predict customer value by defining their future behavior and the revenue they can generate. 

c. Segmentation

Data science is used in banking to perform customer segmentation. An organization must understand how to efficiently manage customers by learning their likes, dislikes, and characteristics. Banks use data science techniques like segmentation, machine learning, and other AI-powered algorithms to divide customers into clusters.

These techniques group customers similarly based on several factors, such as demography, spending habits, financial status, etc. Thus, by creating segments of customers and defining them by their traits, banks can make specific offers and marketing strategies for better customer engagement, satisfaction, and loyalty.

2) Risk Mitigation

While managing customers maximizes banks’ revenue, they must also minimize the risk to stay profitable. Banks must address fraudulent transactions, default-prone customers, and compliance with government regulations to mitigate risk. Banking and data science play a major role in addressing all these risk mitigation-related issues.

a. Fraud Detection

Fraud detection and its prevention are fundamental to risk mitigation. Banks employ AI tools to detect numerous types of fraud, such as payment card, invoice redirection, and advance fee fraud. Other kinds of fraud include identity theft, phishing, vishing, smishing, etc.

Through data science, Banks can identify if a customer has stolen someone’s identity (e.g., using someone else’s credit card to make a payment) to flag and freeze the card until the customer’s identity is determined. AI-powered predictive models are based on regular and fraudulent transactions by looking at device and communication data to prevent fraud and mitigate risk for the banks.

b. Credit Risk Assessment

Another aspect of risk mitigation is to prevent banks from giving loans to customers with a high probability of defaulting. The role of data science in open banking has already been discussed. It helps transfer and analyze financial data to third parties like credit score agencies. These scores help banks assess a customer’s risk level, thus underlining the role of data science in risk mitigation.

Banks can minimize downtime and efficiently schedule maintenance by predicting hardware and software failure and automating failure alerts. Thus, banks can increase their operational efficiency by predicting the failure of IT systems.

c. Optimizing Cash Management

Banks must keep a certain amount of cash in their banks and ATMs. If the amount is lower than needed, it can lead to compliance issues and customer dissatisfaction, as they would fail to provide money when they try to withdraw. Conversely, if the amount of cash exceeds what is needed, it remains idle and unproductive, leading to additional costs for the bank. Storing excess cash securely incurs expenses, ultimately resulting in financial losses for the bank.

Therefore, optimizing cash is critical for banks. Data science is crucial in this area, as banks can set optimal cash flows to the various bank branches and ATMs by predicting cash requirements. AI-powered systems analyze transaction patterns, customer behavior, and seasonal trends to optimize cash management, helping banks reduce costs and risks.

5) Performance Enhancement

An organization’s success is greatly dependent on its employees. The same is true for banks and financial institutions. Data science allows bank employees to enhance their decision-making capabilities and efficiency by automating routine tasks.
