The Changing Landscape of Retail Banking

As BigTech and FinTech firms continue to disrupt the financial services industry, legacy banks today are witnessing their market share for banking services being chipped away due to the superior customer experiences that are offered by these tech firms.

While there have been instances when legacy banks have made large tech investments to compete, the results have not been reassuring. For example, the Chase Pay app developed to rival competition in the mobile payments was discontinued in early 2020 after receiving stiff competition from tech firms, such as Apple Pay, which provided a superior and glitch-free experience to consumers.

As tech firms foray into banking riding on their expertise in cloud computing, customer-facing artificial intelligence, and “big data” customer analytics to provide superior value to customers, banks need to rethink their strategy since it will be increasingly difficult to compete with the tech giants as they acquire significant market share.

A powerful strategy for banks is to adopt an open banking ecosystem that allows third parties, including FinTechs, to build superior user experiences on top of services offered by the banks. Open banking and the API economy allows legacy banks to embrace the tide of disruption they have been opposing for years.

Reviving the Value Proposition for Banks

When Google opened its Maps API to third party developers, it led to the development of several valuable services, such as Uber, that were built atop Google’s geolocation data. When financial institutions open their data to third parties, it is expected to bring in similar valuable products and services that customers can use to manage their finances. This will help banks create an ecosystem that will immensely expand the number of products and services available to customers, as well as the different options available to use them.

While the vast open banking ecosystem will enable innovative and digitalized services, it will also help banks be more transparent and compliant with regulations. The ability to share financial data with third-parties will also open new revenue streams for traditional banks (Exhibit 1). Digital banks in the EU and the UK such as N26 and Fidor are already trying to reinvent banking by building an app ecosystem for customers. For banks that are planning or have just started their open banking journey, an outside-in assessment of their resources and capabilities and designing a target state operating model will be key in guiding them into the new paradigm.

Examples of banks that have already adopted open banking include:

– HSBC launched its Connected Money app in May 2018 in response to the UK’s open banking regulations, allowing customers to view various bank accounts as well as loans, mortgages, and credit cards, in one place

– Barclays claims to be the first UK bank to enable account aggregation inside its mobile banking app. Its open banking feature allows customers to view their account with other banks within Barclays’ mobile app

– Yolt, created by ING, claims to be the first fintech to make a secure connection to the API of several UK banks such as Lloyds Banking Group, RBS and HSBC as well as the APIs of banks such as Monzo and Starling

Exhibit 1: Benefits of Open Banking for Traditional Banks

Open Banking is now evident

Banks have access to some of the most valuable data – customers’ finances; however, until now this vastly relevant data was not being used to benefit anyone. Open Banking encourages banks to release this rich financial data via APIs, in a secure standardized form, so that it can be shared more easily between authorized organizations online – all this while the customer remains in charge of who receives access to their financial data. While this provides a significant opportunity for FinTechs to build innovative customer centric products on top of this data, it also benefits legacy banks by significantly improving the customer experience and outreach of their banking products and services.

The open banking market is currently growing at 24.4% and is expected to reach $43.15 billion by 20261. Although this marks an inevitable shift in the financial sector, the pace has been further accelerated by the pandemic. To operate in the new open-banking paradigm, banks need to build robust and secure open APIs that are standardized to facilitate quick and easy integrations with third parties (Exhibit 2). Open Banking makes it possible to pass information securely to third parties, who can then use it to create valuable products for customers. This is likely to usher in an entirely new financial services ecosystem, in which banks’ roles may shift markedly. Financial institutions who push to be the early adopters of this new way of banking will be able to establish much larger open banking ecosystems, thereby providing customers a vast set of seamless and innovative products to choose from and a much greater value proposition.

Tenets of a Winning Open API strategy

Although banks have been using APIs for a few years now, the adoption has largely been reactive and unstructured. Moreover, the APIs being used were mostly internal to the bank. A survey conducted across 31 European countries revealed that 38% of bank APIs failed to meet EU and UK regulations(2).

To succeed in the new Open Banking paradigm, banks need a winning open API strategy. Often organizations place much focus on building technology while leaving their APIs vulnerable to poor adoption, duplicative efforts, non-reusable technology and reduced ROI.

An effective open API strategy that lays balanced emphasis on all aspects of API development and implementation (Exhibit 4) will boost a bank’s value proposition to the customer as well as their revenue. Banks that successfully leverage open APIs can see increases in revenue by up to 55%(3). Assessing the opportunity to build a robust prioritization roadmap early in the transformation journey is imperative in ensuring that the institution’s open banking implementation efforts remain focused and poised for success.

The 4 tenets of a winning open API strategy are described in more detail in the following sections:

Exhibit 4: Tenets of an effective Open API strategy

A. Adopting and API-first approach

API adoption must be a business-wide venture that touches every part of the organization, right from conceptualization to the development and delivery of different products and services (Exhibit 5). This means everyone should adopt an API-first mindset that embraces new customer value propositions and how APIs facilitate this value creation.

Without strategic steering from the leadership, API programs run the risk of fragmented implementation. Senior leaders should establish and champion the API-first concept throughout every function, at every level. Jeff Bezos, Amazon’s founder, famously mandated  all systems and services to communicate using APIs with no other form of communication allowed. This declaration is attributed to instill an API-first culture which acted as the catalysis for AWS’ rapid growth to a billion-dollar business. API-first allows stakeholders to create ecosystems of applications that are modular, reusable, and extensible, like Lego blocks. This is essential for any financial institution as it allows easy and ready integrations with third-party providers as the industry moves towards the open banking paradigm.

An API-first mindset also fosters a culture of reusability. Business and design teams should always look at what can be reused before developing new services from scratch. Keeping reusability in mind while building APIs will liberate resources and reduce delivery timelines by 3-5x and improve productivity by up to 300%(4).

B. Establishing API Governance

Proper API governance is essential for ensuring that the APIs being built and used are discoverable, consistent, and reusable. API governance also enables the implementation of best practices, such as reusable non-specific API design, which can help banks scale up their API portfolio fast. An effective API governance program should consist of:

– API Catalog and Metadata: Maintain central catalog of all active APIs available to developers. 39% of EU banks have non-responsive APIs listed in their developer portals(5). Keeping metadata for APIs ensures efficient management as the API portfolio expands.

– API Standards: Define API design and usage standards that are compliant with open banking regulations for the region (e.g., PSD2 in the UK). These should also include best practices such as documentation, API-only access to system of records, etc.

– Federated Operating Model: Establish a central team that is responsible for managing architecture and design standards, preferred practices, etc. and acts as the central design authority for all APIs developed across business units, while each business unit has its own team that works with the central team to ensure governance practices are upheld at the very grass roots.

– Performance Monitoring: Ensure the performance and operational resiliency of APIs by monitoring and reporting API utilization, queue sizes, response times and performance failures.

C. Building a Third-party ecosystem 

While setting up open banking capabilities, establishing a thriving ecosystem for customers and developers is a necessary enabler to reap the benefits. Much of these benefits, both to the bank and to the customer, will be rendered ineffective if the bank fails to attract and encourage an active community of developers to use their APIs and build financial services products on top of it.

Banks should actively establish a third-party ecosystem by:

– Offering best-in-class developer portal, API sandboxes and developer tools that allow the third-party developer community seamless access to bank’s APIs. Making sure that the bank offers these functionalities is an essential step towards attracting developers to build, grow and nurture their open banking community. For example, Fiserv has built an extensive developer workspace that provides access to APIs, tools and a sandbox environment for the developers to access, integrate, configure and test the APIs.

– As banks establish their own developer workspaces, they also need to attract top developer talent to use their APIs to build and nurture an ecosystem of products and services. Banks can organize regular events, such as hackathons and knowledge-sharing workshops to attract the first few developers and further expand the third-party developer community.

– As developers start building the open banking ecosystem, it is necessary to maintain high-quality API documentation that is updated regularly and kept relevant with time, both for internal and third-party developers.

– Establishing long-term partnerships with FinTechs across various industries and use cases is another way to ensure that the bank’s ecosystem remains relevant (Exhibit 6). For example, Starling Bank’s Starling Marketplace offers investments via Wealthsimple, pensions via PensionBee, invoice insurance via Nimbla, mortgage origination via Habito and business loans via Growth Street.

D. Monetizing open APIs available to third-parties

Open banking can cause a paradigm shift in how banks generate their revenues today. Open Banking regulations pull banks into the API economy and the broader financial services ecosystem, offering an opportunity to emulate the learnings and successes from tech platform companies and FinTechs. By monetizing APIs, Expedia generated over 85% of its annual revenue, while eBay generated over 60% of its revenue from APIs. In early 2020, Visa agreed to pay $5.3 B for acquiring Plaid, an API-driven Fintech6.

Banks can adopt a direct monetization approach in which providing API access to third-parties is directly linked to the Bank’s revenue. Alternately, banks can also opt for an indirect monetization approach where value delivered from API access is claimed in indirect other ways (Exhibit 7).

These monetization models should not be seen as a one-shot monetization strategy to implement for all bank APIs. Banks should categorize their API portfolio and adopt a monetization approach that is best suited for each API category, market, region, etc. Common ways to classify APIs is:

  • Utility and Helper APIs – These APIs do not provide access to any exclusive information and hence can be offered for free as incentives for developers to onboard on developer portals and start using the bank’s APIs.
  • Data APIs – APIs that share non-monetary data, such as customer profiles, etc. can be classified as Data APIs. These are also the most preferrable APIs for the indirect monetization approach.
  • Transaction APIs – Transaction APIs are used to share transaction or monetary information with third-party developers. Direct monetization approaches are preferred with Transaction APIs.
  • Application Integration and User Interface APIs – APIs categorized under this bucket supports data transfer between multiple apps or UIs and ensures it remains in-sync and up-to-date.

In Closing...

While Open Banking was already picking up speed across Europe and North America, the global pandemic has further accelerated its adoption. The bank’s involvement in the API economy is now not a question of when but how. Banks need to come up with wholesome open API strategies that enable them to build thriving ecosystems of products and services for their customers. At the same time, banks must identify and implement the right data monetization models to maximize their revenue streams from providing third-parties access to their APIs.

To achieve this, banks’ leadership must launch open banking programs that scope the whole value chain that they operate in – instilling reusability during API design to ensuring adoption at launch and then driving developer engagement. Furthermore, the implementation of these open banking programs and API strategies must be assured with effective program management and robust monitoring.

Banks that can move fast, boost API usage, build robust open API portfolio and establish their ecosystems early on will be industry leaders in the new open banking paradigm; in contrast, those who continue to operate via the traditional banking route will continue to lose their market share to open banking leaders and FinTechs.
