The Growing Role of Data Science in Banking
As far as customer service delivery and operations models are concerned, the banking industry has evolved over the years. Nevertheless, most banks still haven't integrated analytics into their core culture, decisions, and business operations. According to a recent McKinsey report, more than 20 banks in the Middle East, Europe, and Africa are at different levels of analytics maturity. Data analytics efforts were matched with business goals by 30 % of banks surveyed.
How is Data Science Used in Banking and Finance?
Data Science in banking and finance is revolutionizing the banking industry through its implementation. The banking industry is constantly seeking better ways to identify customers so that they can increase customer loyalty by improving operational efficiency.
For efficient customer interactions, banks are analyzing a large amount of available transaction data to identify patterns.
Data Science in the banking sector uses customer data including previous history, transactions, trends, and communication.
Due to the fact that this data is mostly unstructured, extracting insights from it is a difficult task.
The analysis of data can be done in many ways, such as Machine Learning, data fusion, signal processing, data integration, natural language processing, etc. As part of their customer segmentation processes and fraud detection, data science in banking is used to perform various important tasks.
Data Science Applications in Banking
Petabytes and terabytes of customer information are being stored by some of the world's largest banks every day. It would mean abandoning one of the key development vectors if these data were not used and their analysis was not made available. The motive of data science jobs in banks to employ data science in finance is clear, r, i.e., to increase efficiency as much as possible. However, to understand the data science use cases in banking one needs to go through a part-time Data Science Bootcamp.
Top 9 Use Cases of Data Science in the Banking Domain
Listed below are the top 9 use cases of data science in banking domain:
1. Fraud Detection
Fraud detection applications may damage the bank's reputation, which is why the financial sector spends billions of dollars every year on data science in banking and financial services. Detecting fraudulent activities requires the use of data science to collect, summarize, and predict the customer database. Before data science/big data, it was impossible for data science for banking professionals to analyze customer records to generate accurate information. AI Machine Learning and can assist banks in preventing fraud.
By using a variety of parameters, such as purchase amount, location, merchant, time and others, data models can be developed to analyze credit card frauds.
2. Managing Customer Data
Data is collected, analyzed, and stored in massive quantities by banks. The goal should not only be to ensure compliance with the law, but rather to learn about their clients in order to generate revenue opportunities using machine learning and data science tools.
A growing number of people are using digital banking nowadays. Consequently, data scientists must isolate the most relevant customer data. Data specialists can then use machine learning models to isolate and process only the most relevant client information to improve business decision-making using the information about customers' preferences, interactions, and behaviors, allowing banks to unlock revenue opportunities by processing only the most relevant information.
3. Risk Modeling
Investment banking data science projects prioritize risk modeling because it regulates banking activities and play a critical role in pricing financial instruments. Corporate finance, mergers and acquisitions, corporate restructuring and reorganizations, and investment banking involve evaluating the net worth of companies to build capital for corporate financing.
This is why the concept of risk modeling has become important to banks, and the best way to assess it is by utilizing the tools and information available through data science. Through the use of Big Data, innovators are now leveraging the power of new technology to make better risk-based decisions through the use of data-driven decision-making processes.
4. Customized Marketing
Personalized and customized marketing is one of the ways in which data science in banking allows for effective customer interaction. To present the most appropriate offers to a particular consumer, self-learning algorithms analyze the accumulated information. The company, therefore, benefits from expanding its product and service offerings, and from increased sales.
5. Customer Lifetime Value Prediction
A business's customer lifetime value estimates the total value that will be derived from their relationship with a customer over the course of their relationship. To generate higher profitability and growth, this measure plays a vital role in creating and sustaining relationships with customers.
It is becoming increasingly difficult for banks to acquire and retain profitable customers. Due to increased competition, banks need to focus their resources efficiently by taking a 360-degree view of each customer. Data science plays a key role here. It is first necessary to consider a wide range of data, such as client attrition and acquisition, the use of various banking services and products, the profitability and volume of those products and services, as well as other client characteristics like geography, demographics, and market.
It is often necessary to clean and manipulate this data to make it usable and meaningful. A bank's clients vary greatly in terms of their profiles, products, and services, and their expectations and behaviors. Generalized linear models, regression trees, classification, and stepwise regression are some of the tools and approaches that data scientists can use to develop a CLV model. To maintain good customer relations and improve profitability and growth, one of the most important processes is to build a predictive model that determines future marketing strategies based on CLV.
6. Customer Segmentation
For the purpose of segmenting their customers, banks perform Customer Segmentation. Customers can be segmented based on their behavior, known as behavioral segmentation, or through their demographic characteristics, known as demographic segmentation.
Religion, age, gender, income, and other factors might be included in the demographic segmentation.
Banking companies benefit from customer segmentation by investing their time and resources in the right places. A variety of application of data science in banking techniques can be used by banks, such as logistic regression, decision trees, clustering, etc. The CLV can be predicted accordingly for different segments of customers based on these. To identify low-value and high-value segments of customers.
By segmenting their customers, organizations can maximize their sales by utilizing their resources effectively. Furthermore, it is used for improving customer loyalty and providing better customer service.
7. Customer Support
It's imperative to maintain a productive long-term relationship with your customers by providing outstanding customer support. Supporting customers is an important but broad aspect of customer service in the banking industry. As service-based businesses, banks are primarily involved in providing services to their customers. Interacting with customers and responding to their queries and complaints in a timely and thorough manner are part of this task.
By using data science, a better automation process can be achieved, making it more precise, personal, direct, and productive, as well as cost-effective in terms of employee time.
8. Real-Time and Predictive Analysis
Banking analytics are becoming increasingly important. Since every banking use case is closely related to analytics and data science in banking techniques can help improve banks' analytics strategies. Analytics become more sophisticated and accurate as information variety and availability increase.
Data processing has become more affordable and smaller, thus increasing the amount of data available, indicating signals, rather than just noise. To solve problems efficiently and make strategic decisions, it is important to separate true relevant data from noise. Predictive analytics assist in choosing the right technique for solving the problem identified by real-time analytics. Analyzing the bank workflow in advance can greatly improve results and prevent potential problems.
