Open Banking- The way we see it

Open Banking is a foundational shift in the way banks do business, who they do business with and what they sell. While the term itself has come to be synonymous with an API Economy, the nature of change that it brings goes beyond technology developments, product innovation or regulatory edicts.

Open Banking requires banks to reinvent and reposition their businesses to remain relevant within customer lifestyles and customer journeys. A range of rapidly evolving collaborate-compete business models define the ways of interaction between banks, FinTechs and a wide ecosystem of financial and non-financial partners.

HCL's Open Banking solutions comprise a set of techno-functional frameworks, a well-curated FinTech partner ecosystem, an innovation infrastructure and a depth of engineering and design thinking expertise that help a bank create differentiated Open Banking strategies and implement them.

SOA & API Platform: Life, General & Group Insurance Systems across Singapore, Malaysia and Indonesia

The client’s architecture lacked a standard way of representing the business services and did not allow existing systems to connect efficiently with the outside world. Functionalities tightly coupled with the user interface or portal could not be changed even for minor iterations. This led to:

  • Inhibited growth had increased maintenance cost
  • Continued software maintenance fees for an insignificant amount of ROI
  • Missed revenue due to the lack of innovative products
HCL Solution:

HCL and the client decided to engage in a journey to develop a standardized REST API which would integrate with the back end and provide next-gen, customer-centric solutions. For the implementation, HCL used Spring Boot, Rancher for Microservices, API Gateway from Axway, BitBucket for version control, and CA LISA (DevTest solutions) for service virtualization. Our team selected the top software solutions from specific segments on the basis of cost, speed, and ease of implementation. HCL’s API gateways have security and throttling models that impose limitations on who pulls the data, when, and how frequently the data gets pulled.
