Banks' ability to innovate hinges largely on the condition of their core banking platforms, yet legacy architecture often hampers innovation. Many U.S. banks, more than two in five, still operate on outdated back-end systems originally designed nearly four decades ago. This legacy setup, once valued for stability, now presents challenges such as disparate systems, complex integrations, and inefficient processes. Maintenance alone consumes a significant portion, up to 80 percent, of banks' IT budgets, exacerbating operational inefficiencies.¹

What is middleware?

Middleware serves as a solution for institutions aiming to enhance the functionality of their existing core systems without the need for replacement or conversion.  It acts as a bridge between legacy technologies and new applications, particularly beneficial for banks heavily invested in legacy infrastructure seeking to minimize the risks associated with change.  

By leveraging API-led middleware, financial institutions can facilitate communication between their core banking systems and various customer-facing interfaces, including internal applications, fintech platforms, and customer interfaces.  This approach to core modernization is gaining traction among smaller institutions due to its lower cost and risk profile, while minimizing alterations to legacy systems.

Middleware in banking tech stack offers three key benefits:

Enhanced Agility and Migration Facilitation: By reducing reliance on the core systems, banks can expedite product delivery and streamline future migrations. Integrating a bank's core with an API-based middleware platform not only accelerates access to data but also unlocks avenues for revenue growth. Embracing a middleware layer diminishes core dependencies, facilitates seamless third-party integration, and readies banks for smoother transitions to new cores when needed.

360-Degree Customer View for Enhanced Experience: Middleware platforms offer a centralized hub for integrating customer and internal data, creating a unified source of truth. Through APIs and middleware integrations, banks can construct a holistic 360-degree view of customers across various business lines, leading to seamless and personalized customer experiences.

Fostering Innovation through Fintech Collaboration: APIs play a crucial role in connecting banks with fintech firms, with a majority of banks worldwide incorporating APIs into their business strategies. Collaboration with fintech partners is recognized as a prime strategy for achieving digital transformation and business growth. As banks increasingly explore Banking-as-a-Service (BaaS), middleware solutions play a pivotal role in facilitating seamless integration with fintechs, sparking innovation and external partnerships.
