Big data in banking: Uses and future prospects 

Disruptive technologies that emerged recently are driving a major increase in the number of financial transaction devices. Even more, their number is growing in proportion to the users’ capabilities. On the other hand, more reliable information is required to correctly assess customer needs for individual products. That leads to an increase in the amount of data that requires high-quality collection, structuring, and analysis. 

In this article, we examine the tasks of big data in banking, possible related issues, and ways to implement big data efficiently. 

Do you have any challenges with data in your organization? We can help you.

How has data handling changed so far? 

If earlier bank employees had known customers by sight, the situation would have changed radically today. These are fundamentally new service models. People can get services remotely. As a result, their number grows, whereas paper media slows down processes, and it becomes more difficult for banks to win the favor of customers. 

The task is solved by the total collection of digital personal data. A user electronic portrait is formed — the information is collected from all available sources. The analysis of user behavior also generates additional amounts of data, but online monitoring is indispensable. 

What is big data? 

Big data is an ever-growing volume of information of varying structures and formats. Some of its major sources may include: 

Conventional computer systems are not trained to work with such a variety of data sources, and they can’t cope with them appropriately. 

Impact of big data analytics on the banking sector 

A traditional bank has always been associated with painstaking work with financial securities. However, new technologies have changed the way bank employees work. In recent years, convenient, personalized, and secure solutions have emerged that have never been native to the industry. First of all, these are AI and ML, which are developing at a frantic pace today in various areas. 

The use of big data in banking makes it possible to improve service quality and stimulate customer flow. This leads to the emergence of new products that better meet current requirements, which in turn drives demand, sales, and retention. 

The analysis provides development prospects by improving decision-making and responding to requests. Customers who appreciate convenience are more likely to use mobile apps. In turn, this requires processing larger amounts of information online. Transactions are accelerated and simplified, so there will inevitably be more of them. As a result, the entire industry is modernizing, becoming more profitable, and diving deeper into the latest innovations.

The use of big data in the financial industry

One of the most promising areas today is the in-depth study of user data. Actually, this is a kind of correspondence dialogue with a client, which allows for identifying their requests and, based on them, providing recommendations and services. 

For this, AI-based applications are used; they provide recommendations for reducing costs, preserving savings, and investing. For example, a well-structured notification system works selectively, making it easier for users to pay for services on time, avoiding erroneous payments, etc. 

Tracking transactions in real-time helps you identify habits, optimize performance, predict profit growth patterns in consumer behavior, and offer services at the right time. This increases conversion rates. 

A modern user should receive an answer to any of their questions around the clock. Robots help in this matter — they process requests as quickly as if the client were directly in the department. Moreover, full-on virtual banks are already working perfectly, having abandoned the usual branches with cash desks and other inherent attributes.

The importance of customer experience

It just so happened, but it is an indisputable fact. Due to the specifics of social networks, today’s customers are more willing to share confidential information. Perhaps their attitude towards this issue will not change in the near future. This means that its value will increase. Just one good analysis of mobile apps or social media activity can replace costly and lengthy surveys. 

Comprehensive and in-depth analysis allows you to evaluate receipts to accounts and draw conclusions about the standard level of income/expenses, which sources of income are more stable, and through which channels the client prefers to conduct transactions. 

Understanding the nuances of the user environment allows you to draw conclusions about possible risks and prevent fraud. This makes it easier to make informed decisions, including on the possibility of extending loans and assessing the associated risks. In addition, it helps to cope with compliance checks, audits, and reporting and reduces overhead costs. 

To summarize, banks are using new technologies for the following tasks: 

Big data implementation is highly beneficial for both neobanks and traditional financial institutions, however, it often faces pitfalls and bottlenecks banks must learn to avoid.

Challenges of embracing big data in the financial industry 

As is the case with everything new and complex, the use of big data in the banking sector can have certain problems defined below. 

Legacy infrastructure 

The banking sector innovates too quickly. As a result, most of the existing systems are unable to cope with the growing workload. In collecting, storing, and analyzing data, outdated infrastructure becomes an obstacle that jeopardizes system stability and the implementation of advanced analytics tools. 

Security issues 

The use of systems that are not designed for big data creates risks. The security system must guarantee the sturdy protection of incoming user information. 

Huge data volumes 

When processing a large number of different types of data, there is a possibility of encountering certain technical difficulties. Implementation of big data is in the interests of any financial institution, but some things require the high professionalism of the staff. Therefore, banks should first consider upgrading their existing infrastructure before embarking on a big data strategy. 

Moreover, the amount of data generated during operations grows exponentially over time. Financial organizations should envisage the scalability of their IT ecosystem and its ability to accommodate the increasing amounts of personal and financial data they work with. 

Regulation requirements 

The industry is governed by strict regulatory requirements such as the Fundamental Trading Book Review (FRTB), for instance. Those tend to be scrupulous about privacy, access to user data, and speed of reporting. This can significantly slow down the transition to new technologies; however, there is no other way. 

To use big data, a financial institution must be mature enough, both from a business and IT perspective. Artificially, without the direct need and the existing infrastructure, this is impossible. 

Data quality and integrity 

If the data collection a financial institution possesses contains inaccurate or incomplete data, it can tell negatively on the outcomes of the big data analysis and the organization’s overall functioning. That is why banks should provide first-rate data quality management and ensure their EDW stores only well-structured data that is accurate, complete, consistent, relevant, understandable, and kept in easy-to-read data formats. 

Data silos 

It can happen when a financial institution has numerous departments and branches, each relying on its own (often on-premises) infrastructure and isolated software environment. In this case, data can’t move freely across the organization and serve as the single source of truth. Banks should eliminate all barriers to the free exchange of existing data and promote the formation of a holistic data view accessible to all stakeholders.  

Considerable implementation costs 

High-end big data solutions capable of processing huge quantities of current and historical data are big-ticket items. For smaller banks, launching and maintaining big data ecosystems can be prohibitive, yet this is the only way for contemporary financial organizations to keep abreast of novel trends, retain customers, and hone their competitive edge. 

Skill dearth 

As the application of big data analytics in banking soars, the demand for qualified professionals who can develop such solutions also increases. That is why far-sighted actors in the financial services industry are constantly on a hunt for skilled big data experts who can consult on the peculiarities of its implementation and create a custom big data product to suit an organization’s needs and requirements. 

Customer trust 

Aiming to provide more personalized services, financial organizations track customer behavior and collect heaps of valuable data on their clientele. The latter increasingly voice concerns regarding the way their personal and sensible data is used and clamor for complete transparency of data handling procedures. Without fostering clients’ confidence and reacting adequately to customer feedback, banks can’t hope to build trustful relationships with consumers of their services. 

If financial organizations pay close attention to the above-mentioned aspects of big data implementation, they will pave the way to the successful harnessing of this technology in their future endeavors.
