Legacy core banking systems continue to constrain innovation, consuming over 75% of IT budgets and limiting banks’ ability to compete with digital-native institutions. The path forward lies in decoupling monolithic architectures and transitioning to modular, service-oriented systems that enable agility, scalability, and faster time-to-market.

Global research across more than 300 banking institutions reveals that modernization through decoupled architectures delivers dramatic outcomes including a 3x increase in deployment frequency, 40% lower total cost of ownership, and nearly 77% faster product launches. Approaches like the Strangler Pattern and domain-driven design have proven to accelerate transformation while maintaining business continuity, reducing outages by 70% and integration defects by over 40%.

In this session, financial technology leaders will learn how to design and implement modular modernization strategies that achieve 3.2x ROI, reduce operational complexity, and create a foundation for continuous innovation. Through real-world implementation insights, we’ll explore how API-driven ecosystems, microservices architectures, and composable core banking enable institutions to modernize securely, efficiently, and at scale.
