Banks’ outdated payment infrastructures are increasingly handing market share to faster-moving fintech competitors. As merchants and customers demand seamless digital experiences, real-time processing, and embedded finance options, legacy systems—built for batch processing and slower rails—create bottlenecks that hinder innovation and responsiveness. Industry professionals warn that without urgent modernization, traditional banks risk losing customer relationships as alternatives quietly gain traction.
Tech experts emphasize that updating core infrastructure is no longer optional but essential for competing with digital-first players.
Outdated platforms restrict participation in emerging areas such as real-time payment networks, digital assets, and API-driven embedded services. Fintechs, unburdened by decades-old code, can develop and deploy new capabilities far more rapidly, according to Capgemini’s analysis of global payment trends.
Recent research underscores the scale of the challenge. Accenture’s Payments Technology Reinvention Study reveals that 59% of banks continue to grapple with legacy payments IT systems and infrastructure, limiting their ability to meet evolving customer demands affordably and at speed.
PwC’s Financial Services Industry Survey 2025 finds that 45% of banking executives identify payment and transaction platforms as their single largest competitive threat, while 43% have delayed major technology initiatives due to integration complexities.
Deloitte highlights the need to retire legacy systems in favor of platforms supporting real-time payments, ISO 20022 standards, and scalable interoperability to stay relevant.
EY notes that high maintenance costs and inefficiency from on-premises legacy technology put banks at a disadvantage against cloud-native fintechs that deliver innovation more quickly and at lower cost.
Analysts point to misallocated resources as a core issue.
Many institutions pour budgets into patching existing systems rather than strategic replacement, underestimating the loss of institutional knowledge from outsourcing and staff turnover.
“Banks that treat payments infrastructure as a core strategic priority early on position themselves as leaders,” observes one payments executive.
Forward-thinking institutions are adopting modular, API-first architectures, real-time data frameworks, AI-driven automation, and cloud migration to unlock efficiency and collaboration.
Practical examples illustrate the stakes.
Banks like Cross River have built in-house API-driven cores to power high-volume real-time disbursements, while NatWest launched a separate digital entity on modern technology to serve niche segments without retrofitting legacy platforms.
US Bank has leveraged real-time networks for instant dealer funding, yet fintechs still dominate many adjacent spaces.
Capgemini projects strong growth in instant payments and e-money wallets, signaling accelerating demand that legacy systems struggle to meet.
Experts recommend a holistic approach: mapping current dependencies, reallocating budgets from maintenance to replacement, and exploring “sidecar” models for experimentation.
PwC advocates rethinking processes through cloud adoption and real-time rails, while Accenture stresses reinventing payments technology to capture a multibillion-dollar growth opportunity.
The main takeaway is evident: incremental fixes are no longer sufficient.
As indicated in an update from the American Banker and other outlets, banks must prioritize comprehensive modernization to safeguard customer loyalty, reduce long-term costs, and reclaim ground from disruptive fintechs. Those that act decisively—embracing data-rich, interoperable, and future-ready systems—will thrive in the evolving payments landscape; those that hesitate may find their relevance steadily eroded.
