How does Open Banking help Fintechs to fulfil customer expectations



The world is on the cusp of an epochal transformation in digital financial services. Open Banking Technology is replete with potential business models as social media were 15 years ago and e-commerce 20 years ago. 

Open Banking, fuelled by regulatory, technology, and competitive dynamics, brings hyper-relevant data and platform-based distribution networks to the fold of fintech companies. This helps them deliver a seamless and engaging digital experience that customers are eagerly looking for.

One of the most challenging aspects of Open Banking is the security and compliance concerns. Hence, sharing data only with the consent of the customers (i.e., regulated access) is at the heart of Open Banking Services. However, it is interesting to note, that a study revealed – 60% of Americans choose fintech over privacy!

Let us start by understanding the need for this disruption in the financial services sector called – Open Banking

We are in an era where immediate access to credit card payments, bill payments, mobile recharges, direct debit control, mortgage comparisons and lending, and so much more is achieved with a mere swipe on a smartphone! These apps are powered by financial data available with banks and evolve with the changing need of the hour.

Fintech startups and firms are one of the major drivers of such changes. The sole aim of any startup is to create new products and services that solve a consumer problem and distinguish themselves from their competitors. And why should financial services startups be any different?

Banks are traditionally known to offer services with higher operational costs and complexities. Today, customers look forward to personalized solutions, even in the banking domain. However, the risk-averseness of banks and tech-driven tools aimed at offering hyper-personalized financial solutions by Fintechs have opened the doors for Open Banking Technology worldwide.

Thus, Open Banking System is the process of banks and other financial institutions making data available for regulated service providers to access, use, and share via Application Programming Interfaces (APIs).

Open Banking facilitates the networking of accounts and data across institutions for use by consumers, financial institutions, and Third-Party Service Providers (TPPs). It allows new companies and new products to penetrate the market, by using this data in helpful, and innovative ways.

Application Modernization for ISO 20022 adoption

Listed below are a few of the reasons why Fintechs and Open Banking have become indispensable to end-customers:

  • Greater focus on customer experience over simply offering traditional banking services
  • Ever-growing influence of the internet and smartphones that call for innovative mobile apps
  • Completely online end-to-end cashflow
  • Financial solutions that drastically reduce the turnaround time between two processes as opposed to the conventional operational delays.
  • Comprehensive solutions that bring together diverse applications on a unified platform

Why must Fintechs collaborate with Banks to harness the true potential of the Open Banking System?

In the $400+ billion Open Data Economy, fintechs can influence the entire financial value chain beyond payments and retail banking. They have the technology, strategy, and resources to develop apps and innovative solutions that enhance user experience.

Fintechs aspire to be the one-stop solution to all the banking-related activities of customers (B2B and B2C). However, the requirements for such a transition are uneconomical and time-consuming. Thus, taking away from the core business aspects like technology and innovation.

To leverage the end-benefits of Open Banking Technology, fintechs must partner with traditional banks to facilitate:

Access to Funds

As banks are THE source of money

Access to Data

To monetize internal customer data from banks by channeling into the development of useful financial solutions.

Regulatory Compliance

To ensure compliance with established guidelines that protect customer data

Consumer Confidence

To leverage the inherent consumer loyalty to banks

To process payments

By developing user-centric apps that employ established bank cards like debit cards for transactions.

Open Banking Platform – A Global Perspective

In many nations, Open Banking is finding many takers. In the European Union, the Payment Services Directive, or PSD2, has jump-started growth from small business lending to new payment options like cryptocurrency to more lucrative savings accounts. In fact, customers in the largest trade block are loving it more than ever.

Similar regulatory initiatives are underway around the world in countries like Japan, Singapore, and Australia. Though the US government has been less forthcoming in enacting pro-Open Banking legislation, the Biden administration has given enough hints at boosting pro-Open Banking steps like the executive order issued on June 9,


As on the expected lines, it is tech leaders like CTOs and CIOs of fintech firms who must herald the new path to make customers future-ready by tapping the digital impulses of the times.

Want more market insight on why Open Banking is the go-to for fintechs looking to drive customer acquisition?

Open Platform Banking has enriched the Fintech companies’ goals in the following ways:

  • Open Banking System allows Fintechs to access consumer banking trends alongside individual account details from banks. They leverage these insights to design innovative financial products for end customers.
  • Fintechs get an opportunity to offer frictionless customer experience in real-time through innovative financial tools like PFM, credit services, wealth management, etc.
  • Post pandemic, the use of mobile banking channels has increased by 20-50% and is expected to grow even further. Fintechs have an upper hand with their tech-driven Open Banking business framework to leverage this trend and gain profits.
  • With the vast amounts of data being shared, Fintech firms can bridge the gap between ‘what traditional banks offer’ and ‘what customers expect’ with speed and efficiency.
  • They also get the chance to partner with distinguished banks and access the banking data of their distinguished customers. Conversely, banks must also scout for the best Fintech firms in the market to collaborate with and promote customer acquisition and retention through improved banking services and tools.
  • This partnership allows the freedom to test new ideas beyond the infrastructural and cultural constraints of banks and helps overcome internal obstacles to innovation.

What are the pain points that Fintech firms have to navigate to ensure end-benefits from Open Platform Banking?

As digital transformation is gathering more pace, customers are looking for faster, better, and more seamless experiences. This calls for burning the midnight oil on the part of CTOs and CIOs at Fintechs to be more agile and keep pace with market trends and competition.

To further elaborate the above-showcased challenges, here is a bit of detailed explanation on what it is all about:

  • Since Fintechs bring with them a culture of disruption, tech leaders have to come up with the necessary gateway to innovations as they operate outside the purview of the traditional banking framework.
  • Also, the prime focus of CTOs and CIOs at fintechs must be – bringing out the core competencies while sharing the burdens of compliance, risk, and costs with financial institutions (banks).
  • The Fintechs have to rely on more rigorous systems to continually seek consumer consent for data to be shared.
  • The type and volume of banking data shared are incredibly extensive and Fintechs need high-end software to manage and process the same usefully.
  • The firms also have to consider consumer inertia and the resulting delay in time-to-value when introducing newer financial products and services in the market.
  • They have to be capable of easily building, training, and deploying machine learning models.
  • Fintechs must leverage artificial intelligence (AI) to make real-time predictions much easier.
  • Network externalities are the result of choices made at various levels of the design of a product: data format, GUI metaphors, API, and so on. They decide the level of interoperability, compatibility, and flexibility permitted within the use of the product.
  • Exploring platform envelopment strategy to monetize data from the banks to create new financial products for the consumers – B2C and B2B.

Open Banking Platform significantly enhances user experience, which implies higher automation, more time to focus on other core areas, elimination of manual task hassles, and eventually cost-saving for businesses (B2B) and better ways to spend, borrow, and invest for customers (B2C).

How do APIs contribute significantly to a seamless Open Banking experience for Fintechs?

Application Programming Interface (API) enables cross-communication between various systems. Fintech companies use APIs to enable data access in financial transactions among the involved entities like – banks, third-party providers (TPPs), consumers, and websites.

Banks, e-commerce companies, merchants, and similar entities must connect with Fintechs to expand their services and stay competitive in the market. This is achieved through financial solutions like apps and tools innovated by Fintechs with the help of data gained via Open Banking APIs.

APIs are the building blocks that provide a highly-defined and customized infrastructure to access, regulate, and process relevant data. This data is then channeled into creating customer-driven financial products and services.

Security Mechanisms to protect Consumers and Providers and Enablers for Open Banking 

Open Banking lets consumers share their financial data with third-party financial products and service providers. This sharing of data is done through APIs (Application Programming Interfaces), which are a set of software rules that govern how different applications can interact with each other. While Open Banking has the potential to increase competition and drive innovation in the banking sector, it also raises important issues about security. Data sharing between multiple parties is the prime concern amongst customers, and there is a greater risk of it being compromised.
