Core Banking System (CBS)
A Core Banking System (CBS) is the centralized software platform that banks use to manage all their essential processes and operations. For example, account management, transaction processing, loan and deposit services, and customer relationship management.
Crucially, CBS platforms enable real-time processing and update. This means that people across many different branches and digital channels can access key information right away, which is essential for larger financial institutions.
As this software sits at the heart of many different essential processes, modern CBS platforms are also designed to be modular and scalable. This means that they can be integrated with third-party vendors and services easily, typically via the use of APIs. By doing so, banks can easily scale up their businesses and maintain best-of-breed solutions across their tech stack.

Examples
Let’s imagine a mid-sized bank that operates in Switzerland and Luxembourg. In order to stay compliant with all the relevant regulations and provide good customer service, the bank needs to keep track of all its users across both jurisdictions, accounting for digital signups and people visiting the physical branch, perform different levels of Customer Due Diligence for each person, provide services such as loan origination, and a lot more.
This is where a core banking system comes into play. It acts as a central ledger that records all account information, transactions, and service details. In this scenario, we will imagine that it only serves as a ledger, relying on multiple different third-party vendors to tackle different processes. For example, a KYC/KYB provider, a loan servicing provider, a mobile banking provider, and so on.
All of these systems feed right back into the core banking system, allowing all the different branches to gain real-time, accurate data. Core banking systems also often handle processes such as account lifecycle management, transaction processing, and interest calculations, depending on how modular the specific core banking platform is.
