Banks Push for Composable Tech to Match Speed of Modern Business

As the pace of business accelerates and digital-native customers expect near-instant financial services, banks are under pressure to reimagine their technology infrastructure. In a recent industry discussion, banking executives stressed that the integration of technology and business strategy is no longer optional — it’s essential.

The conversation featured insights from banking technology leaders, who noted that traditional core banking systems, designed for a slower era, can no longer keep up with real-time consumer demands. Today’s customers expect the same level of immediacy from financial transactions as they do from streaming services or same-day delivery apps. This shift is forcing banks to move away from siloed systems toward real-time, data-driven, and composable architectures.

Key drivers of this transformation include the need for real-time payment processing, embedded financial services, and seamless data integration across workflows. Customers — both individuals and businesses — now expect financial capabilities to be available directly within their daily operations, not through standalone banking portals. Features once considered innovative, like early wage access and buy now, pay later, are becoming table stakes for commercial clients as well.

To address these expectations, banks are turning to three core architectural pillars: modern middleware, cloud infrastructure, and a data-first mindset. This means adopting API-driven design, investing in cloud platforms that scale with demand, and focusing on data governance to ensure that information flows easily between systems. These technologies help banks deliver timely, relevant financial experiences — a critical factor in today’s competitive environment.

Rather than launching massive, multi-year transformation projects with delayed results, banks are now favoring iterative modernization. Some institutions are creating new digital product lines or launching sidecar platforms, while others take a gradual approach, progressively replacing legacy components over time. What matters most is the ability to demonstrate measurable business value at every step.

Executives also rejected the notion of “future-proofing,” calling it a misleading buzzword. Instead, they emphasized adaptability — building systems and cultures that are capable of evolving with technology and customer expectations. In this view, the true goal of modernization isn’t to eliminate change, but to enable continuous evolution.

Finally, the panel noted that composable banking — once considered a competitive differentiator — has become a baseline expectation. The ability to mix and match services, integrate external tools, and launch products quickly is now crucial for survival. FinTechs, rather than being threats, are often seen as collaborators, offering tools, distribution, and agility that banks can use to their advantage.

In today’s financial landscape, execution is everything. The institutions that move fast, iterate often, and stay close to customer needs are the ones poised to lead in the digital era of banking.
