Bank Core Systems: From Legacy to Cloud-Based Platforms

Bank core systems have been the backbone of banking operations for decades, but they're due for a major overhaul. Many legacy systems are outdated, inflexible, and costly to maintain.

The average age of a bank's core system is around 20 years, with some dating back to the 1980s. This means they're often based on outdated technology that's no longer supported by vendors.

Upgrading to cloud-based platforms can help banks modernize their operations and improve customer experience. Cloud-based core systems offer greater flexibility, scalability, and cost savings compared to traditional on-premise systems.

A study found that 70% of banks plan to move their core systems to the cloud within the next 5 years.

A bank core system is essentially the back-end system that processes daily banking transactions across all branches of a given bank. It's called a core banking system, and the term "CORE" stands for Centralized Online Real-time Environment.

The core banking system is designed to provide 24/7 real-time services for customers, making it a crucial part of a bank's operations. This system connects multiple branches of the same bank.

Core banking services for customers include processing withdrawals and deposits, loan issuance and management, interest calculations, and other relationship management activities. These services are essential for customers to manage their accounts and finances.

A bank's core system integrates with their accounting system to store all account-related information, including account numbers and balances, customer data, and loan payment due dates. This integration helps banks keep track of customer information.

The core banking system also houses a bank's general ledger, which tracks all transactions across the institution using double-entry accounting. This makes it easier for banks to balance their general ledger and track daily figures.

Choosing a provider for your bank's core system is a critical decision that requires careful consideration. The American Bankers Association (ABA) has developed the Principles for Strong Bank-Core Provider Relationships, which offer reasonable standards for a bank's relationship with its core provider and customer base.

These principles emphasize the importance of fair and transparent contracts, adoption of technologies outside of the core provider offering, and access to customer data. This will allow banks to be innovative and competitive.

Community banks and credit unions often outsource their core systems to system providers, with notable providers including Temenos AG, Oracle Financial Services Software, Infosys, and Avaloq.

To conduct a thorough search for a core provider, you can use the sample Core Provider Request for Proposal (RFP) and Request for Information (RFI) Templates developed by the ABA's Core Platform Committee.

These templates can help you conduct rigorous and complete market research when choosing a core provider, and can be customized to meet your individual business needs.

Bankers who have been through a core platform conversion share their first-hand experiences and best practices to make your conversion a success.

Converting to a new core platform can be a daunting task, but it's essential for modernizing your bank's operations. Many financial institutions are now focusing on developing front ends such as websites, mobile applications, and multi-channel solutions to extend the life of their core banking system.

However, this is not a long-term solution, and the cost of running and maintaining core banking systems is becoming increasingly high. In some cases, it's even comparable to the cost of implementing a new generation core banking platform.

To meet this challenge, financial institutions must take a strategic and technical approach, decommissioning their existing core banking system while testing multiple core banking platforms on parts of their product portfolio. This process can be tricky, and the return on investment is often difficult to measure, but it's undoubtedly the best option.

To make this transition smoother, consider using a test-and-learn approach, like Skaleet, which allows you to experiment with its core banking platform as part of a project or product launch. This way, you can test the platform solution while acquiring new customers and gradually migrating.

Here are some key considerations for a successful core platform conversion:

A modular core banking system is designed with independent transaction management functions, separate from banking services like new account creation and loan management. This approach provides greater configurability and scalability.

In contrast to monolithic architectures, today's core banking platforms favor microservices-based architectures, which offer greater configurability, scalability, and robustness. This enables financial institutions to orchestrate different services to introduce new products.

A key innovation in core banking is the use of APIs, which act as intermediaries between different applications within the core banking system. APIs allow different modules to connect and work together, enabling financial institutions to provide additional services through APIs.

Here are some benefits of the orchestrator approach in core banking:

The core banking system has become an outdated model. It hinders the scalability of services offered by financial institutions due to its architecture and infrastructure.

Legacy systems are inflexible and slow to change, making it challenging for financial institutions to comply with new regulations and develop new products/services.

The core banking system lacks performance in terms of data storage and utilization, leading to data duplication within the system.

Strong business logic and siloed data storage make creating relationships between customers and products demanding.

Legacy systems can't handle the scalability demanded by today's environment, making it impossible to meet new customer expectations and regulatory requirements.

Banks and financial institutions have often preferred to stick with their legacy platforms due to costs, delays, service disruptions, and technical migration issues.

Here are some limitations of legacy core banking systems:

Cloud-oriented core banking is a game-changer for financial institutions. It allows them to free themselves from the burden of maintaining a data center, which can be costly and complex.

By adopting the cloud, financial institutions can take advantage of a scalable environment that's built from the ground up to run in the cloud. This means better data management and security with automated backups.

A cloud-native solution offers a controlled budget based on global offerings that include data hosting, maintenance, updates, and more. This approach also provides a scalable and extensible model that can adapt as your business grows.

Cloud-agnostic core banking platforms ensure data sovereignty and reduce risk by allowing data to be hosted on any cloud infrastructure. This means financial institutions can move their platform from one cloud environment to another as needed.

Here are some key benefits of cloud-oriented core banking:

Overall, cloud-oriented core banking is a smart choice for financial institutions looking to modernize their systems and stay competitive in a rapidly changing market.

Computer software has revolutionized the banking industry by reducing manual work and increasing efficiency.

Advancements in Internet and information technology have led to the development of software that performs core operations of banking, such as recording transactions and maintaining customer records.

Core banking systems are back-end systems that process daily banking transactions and post updates to accounts and other financial records.

These systems typically include deposit, loan, and credit-processing capabilities, with interfaces to general ledger systems and reporting tools.

Many banks implement custom applications for core banking, while others use commercial independent software vendor packages.

Legacy software is a major issue in terms of allocating resources, making spending on these systems a significant expense.

Modern Core Banking Systems tend to follow a "lean core" philosophy, where the core system has only basic functionalities like General Ledger and transaction posting.

One option is to adopt a cloud-based system, which can provide greater flexibility and scalability. This can be a cost-effective solution, as it eliminates the need for upfront hardware and maintenance costs.

Another option is to implement a hybrid system, which combines on-premise and cloud-based components. This can be a good choice for banks that need to maintain some level of control over their systems while still benefiting from cloud-based scalability.

Ultimately, the best solution will depend on your bank's specific needs and goals.
