Open Banking APIs: What, Why, When, Who, Where

      Posted by Javier Castillo on Sep 27, 2019 in

      Open Banking APIs, and what they can do for the banking and financial industry, have received a lot of attention recently. Ever since the EU’s PSD2 and the UK's Open Banking Standard was introduced at the start of 2018, Open Banking initiatives, lead by regulatory and technological developments, continue to advance and proliferate.

      For those unfamiliar with the subject, the aim of Open Banking is to level the playing field for banks and tech companies and in the process provide a better experience for consumers.

      Who wouldn't want that?

      The continued effort behind Open Banking reform means that banks and financial institutions, using APIs, will have to open up and allow the sharing of a users financial data, such as spending habits and payments, with authorized third-party providers.

      As you can imagine, the entire financial industry will eventually flow through APIs that facilitate the exchange of information and data.

      What Are Open Banking APIs?

      The PSD2 directive that came into being in January 2018 meant that Open Banking and the use of open APIs would enable third-party developers to build apps, websites, and services around banks and financial institutions.

      These APIs, or application program interfaces, are used as a secure method of communication between third-parties and online banking systems. Typically this communication comes from FinTechs (that create the API) and banks that make use of that API.

      This allows a secure way of giving providers access to a user’s financial information such as balances, account information, cash flow, and transactions.
      In the UK, banks are now required, by law, to provide their client’s account information to companies in other industries such as payment initiators or account aggregators.

      On the flip-side, and by using APIs, banks combine the digital services offered by other companies on their own platforms.

      As Onur Simsek, Product Manager at Strands, explains, “Open Banking APIs enables banks by expanding their customer reach to address unserved and underserved areas. By doing so, it helps banks create new revenue streams from the distribution of services over third-parties. Also, partnering with third-parties will generate new opportunities to accelerate the bank’s innovation efforts and bring new products and business models to market.”

      Today, there are 3 types of APIs that banks can make use of:

      1. Private APIs - these are internal and inherent of the bank or financial institution and are used for information exchange within the same private system.

      2. Partner APIs - these are open and built for strategic business partners to the bank or financial institution.

      3. Open APIs - these make data available to third-parties (that aren’t necessarily partners of or working directly with the bank of financial institution).

      Why Are Open Banking APIs Important?

      APIs are important because they allow one computer program to be used by another. Thus, APIs are a means by which two different programs are able to communicate.

      And, when you have banks that have old core-banking systems built several decades ago, APIs allow them to tap into new technologies.

      By leveraging Open Banking APIs, banks not only update their IT infrastructures, but they can also increase customer satisfaction, expand their product lines and distribution channels, provide better services and customer support, and continue to stay ahead of the curve.

      Banks that utilize API services allow them to deliver excellent and innovative user experience that ultimately helps them grow and stay relevant in this new era of increasing competition.

      When Did Open Banking APIs Manifest?

      APIs are nothing new, they have been around now for about 20 years, but for banking and the financial industry, their use has only grown in the last couple years.

      Since PSD2 came into being in January 2018, Open Banking and the buildout and implementation of APIs to service this new concept began to increase.

      Following in the footsteps of companies like Paypal and Google, banks that began experimenting early on with APIs and collaborating with third-parties included big names such as BBVA, Citibank, and Capital One.

      what are open banking apis

      According to a 2015 article from American Banker, “by sharing APIs to their proprietary software with nimbler, unregulated tech companies, the argument goes, banks can innovate much faster than they could by limiting application development to their own compliance-inhibited, resourced-strapped IT organizations.”

      Today, in 2019, that still rings true as banks that embrace Open Banking and the use of APIs are driving innovation and opening up new opportunities which improve their bottom lines.

      Who Benefits From Open Banking APIs?

      Capgemini World FinTech Report 2019 states that 89% of banks leverage APIs to collaborate with FinTech firms as part of their business strategy.

      Basically, APIs support and help banks in their digital transformation. As a result, they also help banks monetize their use and increase revenues by connecting with fintechs, new business processes, external partners, vendors, and others, in a more secure and less costly manner.
      It is more cost-effective to “plug and play” the technology of external companies, rather than having to build that same technology internally.

      Banks can also benefit by generating new customer insights as well as providing an abundance of services that they themselves don't have to spend time, money, and resources developing. This all helps banks provide a larger value-chain.

      As for customers, they can access and benefit from comparing different product offerings and choosing the best one. It’s also important to point out that customers are always in control of what transaction data they allow third-parties to access and they can stop access to their information at any time.

      When it comes to SMEs, they benefit from having access to other services aside from banking and loans. These include things such as cash flow and payroll management.

      Furthermore, SMEs can gain from an array of new services that help them reduce operational expenses, automate cash flow forecasting, get faster settlements, and have better overall financial management, among other things.

      As Finextra points out, “Open Banking APIs will transform the way customers apply for credit and other products, enabling individuals and businesses to share the bank transaction data seamlessly and securely online without having to fill-out paperwork, scan their data and provide information manually repeatedly.”

      At Strands we offer our API Hub solution which offers banks a single interface from which to connect to external services in an easy and secure way. Banks can take advantage of this solution by providing third-party services and the best offers to customers, and by doing so, retain more customers, boost revenue, cross & upsell, and improve their underwriting capabilities.


      Where Will Open Banking APIs Spread To?

      We are at the forefront of Open Banking APIs and the benefit and reach it can have around the world. New developments are beginning to take shape outside of Europe. Australia, for example, is in the process of developing and passing their own open banking regulations and mandates.



      Yet, because different adoption-rates are playing out in each country, this hinders the Open Banking phenomenon from growing together and universally.

      Financial services industry legislation and laws are not the same in every country, and due to that, countries and markets will create and pass their own Open Banking regulations and frameworks at their own pace. This might prove counterproductive and have unintended consequences.

      As PaymentsJournal points out, “As APIs feature more prominently in the banking industry, the need for API standardization grows. There needs to be common rules and guidelines that govern how APIs are made and communicate with one another for innovation to occur.”

      What is certain is that Open Banking APIs will continue to evolve and extend to incorporate additional services and offerings, apart from finance-related ones.

      Open Banking and the corresponding technologies are driving rapid changes throughout the financial services industry. More technological advancement and a continued relationship between banking and fintech will undoubtedly continue, and that will help create innovative solutions that meet the expectations of the future.
