Getting to the core

The BCG Platinion Core Banking Architecture Report 2022


The BCG Platinion Core Banking Architecture Report 2022 will provide you with a holistic, under the hood view of some leading core banking solutions – a market premiere as the first of its kind.

Building a future-proof architecture

In the age of digitalization, financial services are a highly dynamic market. Established institutions, Fintechs and Neobanks are competing for customers who think and act ever more digitally and have swiftly changing requirements. In addition, there are rapid technical and macroeconomic developments. To keep up in this environment, banks must be able to adapt quickly to changing circumstances. Whether they are able to do so in each case depends crucially on their ability to modernize their IT landscape.


The core banking system plays a decisive role here. For fintechs and neobanks, the right choice determines how swiftly they can start their core business. Established financial service providers, on the other hand, are often held back by legacy cores. This makes setting up a modern core banking system a challenge if they want to keep up with a constantly changing ecosystem of providers and competitors. Currently, more and more business leaders are making the decision to massively rebuild or completely replace the existing system of their bank.


But which core banking system is best for the individual institution? One thing is clear: “The best core banking system” does not exist. Each solution has its individual strengths and weaknesses. The decision for or against a particular product is an institution-specific weighing process. The bank strategy sets the direction. And the core banking system with its business-functional and technical capabilities must fit in with it.


To make the right choice, bank CIOs and their teams need to have detailed information on the architecture of the leading core banking solutions. It is also useful to have the profile of the business functions covered by each vendor to make an informed decision for or against a core banking system possible.


To help decision-makers get started on this topic, BCG Platinion has for the first time compiled a comprehensive overview of core banking solutions from leading vendors. It offers a holistic “under the hood” view of leading core banking solutions. The overview makes it much easier for CEOs and CIOs to find the right system for their bank.
