    Open banking is already a reality in many countries, bringing innovation for customers and opportunities for banks and financial institutions.

    It gives customers the convenience to manage their finances using a variety of third-party tools that can cater to their specific needs 24/7, while giving financial institutions the opportunity to monetise their data via the creation of new products and services to access to new markets.


    Open Banking is marching forward - is your organisation ready?

    At the core of the Open Banking model is the tenet that customers own their data, and not the institutions entrusted with it, and that it should be accessible to customers via third-party platforms providing competitive products and services to their benefit.

    Around the world, this view has been gaining tremendous traction, and is being championed both by customers as a data ownership issue, as well as by forward-thinking banks and fintechs as a tectonic shift in new business opportunities.

    The roadmap and timeline to such a significant change involving so many organisations differ from country to country and region to region, with the guidance of regulatory agencies and advisory boards in different capacities (more on that later).

    Whether you are a big financial organisation or a nimble fintech, there's something for you

    As a regulation compliance exercise or to embrace new technology, the way your organisation handles customer data is being radically transformed as a result of regulations such as the General Data Protection Regulation (GDPR) and Revised Payment Services Directive (PSD2) in Europe and the Consumer Data Right (CDR) in Australia.

    Traditional banks accustomed to operate in the traditional model will have to quickly adapt their businesses to this new reality if they want to survive. One of the advantages they have on the other hand, is their experience in analysing customer needs and behaviour in order to create products and services. Their existing tools and processes can be leveraged to kick-start their transformation and position themselves as Account Information Service Providers (AISP) and Payment Initiation Service Providers (PISP).

    This strategy has been demonstrably successful in creating new revenue channels in other industries, and is waiting to also be embraced by the banking sector. 50% of’s revenue is generated from APIs which are used to create apps available via its marketplace, and a staggering 90% of travel fare aggregator’s revenue comes from the use of APIs*.

    Traditional banking vs. Open Banking

    How Open Banking differs from traditional bankingTraditional banking has been restrictive both for consumers and banks. Customers can interact with only one institution at a time,which makes the management of their finances a cumbersome and inefficient exercise. Banks on the other side, have a too limited view of their customers’ finances, which impacts their ability to understand their behaviours and financial lives and consequently offers the most appropriate products and services.

    Open Banking implemented via APIs benefits both sides by giving customers the ability to use applications that centralise information from more than one institution, and by giving banks the ability to use APIs and sidestep issues with legacy applications and infrastructure to offer innovative and expedite solutions. 

    Open banking needs open source

    Open source solutions are backed by a vibrant community of software developers, pooling their best ideas to create great software. The advantages of using open source solutions are:

    • Open source is no longer a niche market, and can be found in major current and emerging technologies
    • Open source has been the model of choice for enterprises going through their digital transformation journeys
    • Open source pools the talents of a bright and talented community of developers driven by passion of technology
    • Problems shared with the open source community receive a large number of responses/solution from specialised developers

    Banks and other types of financial institutions may initially balk at the idea of open source solutions, given the high degree of control and security required by their business in order to protect their customer data. But in fact, an open source development framework results in robust and hardened applications.
