“Responding to open banking is a non-negotiable.”
David Lindberg, CEO of the UK Retail Bank
If we see the trend over the last few years, a silent player in the data game, application programming interface (APIs) has been working to revolutionize how two systems can interact securely with each other. The increase in cloud adoption and increased network bandwidth has made it more relevant than before (I know that Postman and its valuation came to your mind!)
Banking is as old a concept as trade and today we interact with APIs on a daily basis, knowingly or unknowingly. Open Banking is a framework which is built entirely on the foundation of APIs and it has the potential to transform the way we deal with banking services today.
We chose to talk about open banking in this article as 74% of financial institutions see data analytics as the most relevant technology to invest in (source: PwC Global FinTech Report).
The Indian market is currently geared to open up new opportunities for ML & AI use cases with the neo bank market valued at approximately $500Mn and expected to reach $15,000 million by 2027.

If we want to evaluate the success of the open banking framework, we should study the use case of Plaid, established in 2012. Visa recently paid $5.3Bn to acquire the company which facilitates connecting financial apps to the banks, that presents a big number. So is Plaid’s empire which interacts with more than 2,500 digital finance products today and with more than 10,000 developers building on the Plaid platform at present.
To answer the question whether the opportunity is lucrative enough or not, let’s glance at a few numbers from the UK market, which essentially initiated the Open Banking revolution.

What is Open Banking essentially?
Open banking is a framework where banks and other institutions open up customer data and facilitate transactions using APIs which enables third party organizations to build new apps and services.
The following diagram clearly talks about the different entities in the Open Banking framework and how APIs follow a consent based architecture which puts customer as a authorizing authority unlike credit bureaus where the data can be fetched without any user authorization:
Potential Business Use Cases for Open Banking Platforms
Access to user transaction data and feasibility of interacting with core banking systems, enables financial apps to build smarter use cases related to everything money.
The following table summarizes a few of such use cases.
|Entity||Description||Example use cases|
|Personal Finance Advisor||Uplifting users towards better savings and investments||
|Financial Inclusion||Giving access to financial services to those who were not able to access it before||
|Enhanced Processes||Automation and integration of intelligent processes||
|Ease of use||Customer need focussed products||

Fully Digital Banks
Fully digital banks are the entities which provide the entire suite of services which a typical bank provides but with a limited (or No) physical presence.
RBI as a law doesn’t apply fully digital banking licenses today but startups like Jupiter, Neo, NiYo have figured a way out by partnering with already existing banks and building products using the APIs with the partner banks.
Monzo, NuBank & Revolut are few names which one can not miss while talking about Open Banking or Neobanks.
In fact, an estimated 40,000 people open a Monzo account every week.
The following two graphs show the growth in terms of accounts for Monzo and Revolut.
NuBank which was established in 2015 in Brazil has recently clocked more than 25M and valued at $10Bn – Added 42,000 new customers daily (Jan-March’20).

Interestingly, more than 80% of NuBank customers come through unpaid referrals.

Where does India stand in this open banking revolution?
India may have joined the movement a bit later as compared to our western counterparts but we have built a very strong foundation for facilitating any API based ecosystem.
Providing a digital identity to more than a billion people through Aadhaar was the first step which was followed by UPI, which is undoubtedly one of the most robust and secured payment solutions built over API framework.
The following slide shows the growth of IndiaStack over the years:
Today we have around 1.26 billion Indians registered on the Aadhaar database and apart from the central bank there are at least 50 companies which are leveraging UPI’s app for their own wallets. In June 2020, UPI has processed more than 1.3 billion financial transactions and currently the underlying tech is being revamped to support 1 billion UPI transactions per day.
Coming to the core philosophy of open banking, Account Aggregator (AA) framework is the talk of the town in India.
AA allows financial information users (e.g., Lending app) to access customers data (with consent) from financial information providers (e.g., SBI) for various services. Apart from banking, entities like GST, pension funds, insurance, mutual funds etc might also be a part of the framework. RBI has already given licenses across the categories and we might see adoption and uses in coming months.

What is the meaning of open banking?
Open banking is very often referred to as 'open bank data.' Open banking is a banking practice where third-party financial service providers are given access to customer banking, transaction, and other financial data from banks and non-bank financial organizations through application programming interfaces (APIs). Open banking allows users, financial institutions, and third-party service providers to network accounts and data across institutions for usage by consumers, financial institutions, and other service providers. Open banking is quickly becoming a key source of innovation, potentially transforming the financial sector.
How is data science used in open banking?
When addressing the open banking movement, the relevance of data science in finance cannot be emphasized. Data science specifies how these data exchanges are structured, how the data's meaning is standardized, and how open banking systems may evaluate the data. Meanwhile, artificial intelligence and machine learning have enhanced and automated how third parties draw conclusions from data and how financial institutions make data-driven choices.
What is the benefit of using API in Open Banking?
Thanks to open banking, people and companies may benefit from open banking APIs (which essentially boils down to increased innovation). APIs are essential in and of themselves because they enable third-party providers with secure and efficient access to data from financial institutions. Open banking APIs should make it simpler for new fintech services to focus on providing a fantastic user experience because they can rely on the solid, fundamental banking infrastructure that financial institutions have already built.
