As financial institutions in the Asia-Pacific (APAC) region work to stay relevant in the rapidly evolving digital landscape, modernizing their core banking systems has become a crucial strategy. These systems are the foundation of a bank’s operations, and keeping them up to date can provide significant benefits. While the cost of upgrading core banking systems can be substantial, with projects ranging from US$50 million to US$200 million, the rewards of modernization make it a worthwhile investment.

Modern core banking platforms not only improve efficiency and reduce operational costs but also create opportunities for financial institutions to develop new products and services, helping them stay competitive in a fast-paced market. Additionally, integrated solutions provided by modern platforms can streamline various banking functions, which can lead to long-term cost savings.

However, many banks face challenges in keeping their core banking systems up to date. The complexity of these systems, coupled with the significant financial investment required for large-scale updates, often makes such projects daunting. According to McKinsey, only about 30% of core banking system upgrades succeed in completing the full transition, including data migration and product integration. As a result, many financial institutions are turning to progressive modernization as a more practical and efficient approach to upgrading their systems.

Three Approaches to Core Banking System Modernization

Core banking system modernization can be approached in three primary ways:

1. Complete System Overhaul
   The most expensive and disruptive option, this approach involves completely replacing the existing core banking system with a new one. This method often requires significant downtime and extensive data migration, making it less attractive for many institutions.
2. Gradual Modernization
   This approach focuses on updating core banking components over time. By upgrading one or two elements at a time, financial institutions can better control the process and reduce the costs associated with a full overhaul. This approach strikes a balance between cost and control.
3. Progressive Modernization
   A more cost-effective option, progressive modernization allows banks to adopt modern technologies without the financial strain of a complete system replacement. By making incremental updates, banks can keep their existing systems stable while benefiting from innovations that improve efficiency and customer experience.

The Benefits of Progressive Modernization

Progressive modernization enables banks to upgrade their core components gradually, ensuring that their systems remain stable while adapting to new technologies. This approach offers several advantages:

• Cost Savings: By upgrading in stages, banks avoid the large upfront costs of full system replacements.
• Innovation: Financial institutions can incorporate new technologies quickly, allowing them to stay competitive and offer innovative products and services.
• Improved Customer Experience: As banks modernize their systems, they can provide better and more personalized services to their customers.
• Enhanced Scalability: Modern systems can scale more easily to accommodate growth, making it simpler for banks to expand into new markets or customer segments.
• Better Security: With each update, security measures can be improved, reducing the risk of cyber threats.

Progressive modernization allows financial institutions to adopt an agile approach, quickly responding to market changes, customer needs, and new technological advancements.

Key Challenges in Modernizing Core Banking Systems

While the benefits of modernization are clear, several challenges complicate the process:

• Legacy Systems
  Core banking systems in APAC are highly complex and often rely on outdated technology. For instance, in China, many banks still use Oracle’s iBanking platform, which provides essential banking services but can be difficult to integrate with newer technologies. Integrating legacy systems with modern solutions can be a daunting task, and without the right technology partners, the scope of modernization is limited.
• Deployment Model
  Many banks in APAC manage their core banking systems in-house, which can make upgrades even more challenging. These institutions must balance maintaining legacy systems with implementing new technologies, all while ensuring data integrity, security, and customer satisfaction. Some banks may consider adopting a cloud-based or SaaS (Software as a Service) model to ease maintenance and improve efficiency. However, this shift can raise concerns about regulatory compliance and data security, requiring significant effort to educate stakeholders on the benefits of such a transition.
• Cost and Time Constraints
  Upgrading core banking systems is a significant financial commitment. Full replacements can cost millions and take months or even years to complete. Additionally, staff must be retrained, and processes adjusted, which can delay the transition. Once an upgrade begins, it’s often difficult or impossible to revert to the old system, adding another layer of complexity.
• Stakeholder Buy-in
  Convincing key stakeholders—such as board members, regulators, and shareholders—of the necessity of a core banking system upgrade can be a significant hurdle. Clear communication is essential to ensure all parties understand the long-term benefits of modernization and are aligned with the institution’s strategy.

The Future of Core Banking in APAC

As the demand for modern banking services grows, the importance of upgrading core banking systems in APAC continues to rise. By embracing progressive modernization, financial institutions can improve efficiency, reduce costs, and enhance customer experience while maintaining system stability.

Furthermore, core banking systems are evolving alongside trends such as cloud computing and artificial intelligence (AI). Today’s systems are no longer limited to basic functions like account management and transfers. They now include a wide range of innovative services aimed at enhancing customer experience, increasing operational efficiency, and providing greater insights into customer behavior and financial performance.

To stay competitive, banks must continue to evolve their core banking systems and take advantage of the opportunities that modern technologies provide. By adopting a progressive modernization strategy, APAC financial institutions can ensure they are well-equipped to meet the challenges of the future while offering innovative solutions to their customers.
