Is Big Data empowering the Banking industry?

The amount of data that we generate everyday is truly staggering. At the moment, 2.5 quintillion bytes of data is created each day and is estimated to increase with the growth of Internet of Things (IoT). For instance, this consists of every credit card transaction you make, your texts across messaging platforms, even the webpage you open. Now that you have an idea of these numbers, just imagine how much data we collectively generate every single day. This leads to endless opportunities for many businesses who are keen to capitalize on the data, likewise Banking industry is no exception.

Presently, Digital banking is used by more than 2 billion people i.e almost half of world’s adult population. Hence, financial institutions have enough data at hand to rethink the way they operate, to become more efficient, customer-centric and as result more profitable. Banks have already been digitized which can be seen in Figure 1, now they are all set to get datafied.

However, the ultimate question is “How do the banks get most of your data to stay ahead in the competition?”In this blog, we will discuss the applications of big data in banking sector.


The banking industry is among many industries which have enormous amounts of useful data about their customers but only few banks are utilizing this piece of valuable information to enhance the customer experience and using the data information to prevent fraudulent activities. According to recent research, only 37% of customers have responded positively saying banks understand their preferences and needs. It reflects, that banks are finding it a massive challenge to handle an ocean of informative data, which can be due to lack of skilled work force, unstructured data, high cost associated in storage and much more.However, the banks have realised the significance of data and gradually they have started applying Big Data Technology. The results are here, with almost sevenfold increase in the volume of data in past few years and experts believe this will propel the Banking industry. In this regard, Fintech firms have radically modified the financial landscape by facilitating the big data applications and complex calculations to financial decision making.


FinTech companies are proactive, and they have the ability to handle big data to provide unparalleled levels of convenience. In this process they are taking away a sizable chunk of traditional finance firms revenue by eliminating friction for customers, for instance payment companies like Paypal and Upstart now allow customers to easily make payments online and take part in peer-to-peer lending. On the other hand, traditional financial firms lack the infrastructure to support these type of services and are unable to understand how customers are using specific applications. They tend to rely on surveys rather than real-time data to identify how customers are responding to their services. The bottom line is that unless traditional financial firms can catch up to Fintech companies in terms of embracing Big Data, they will not survive.

Despite the aforementioned challenges, the advantage of big data in banking easily justifies any risk.
