Why Rip-and-Replace Method is Holding Financial Institutions Back from True Modernization
- Legacy banking cores drain profits and trust, making modernization an urgent strategic priority
- AI fintech modernizes workflows, closes skills gaps, and cuts fraud and errors
- Fintech partnerships accelerate transformation, improve experiences, and drive growth
When thinking about the concept of platform modernization, many organizations take the age-old approach of rip-and-replace -- taking legacy solutions or systems and simply replacing them with something new. However, this is not the case. To truly achieve platform modernization, it means transitioning from legacy systems down to the core.
In an article from our friends at FIS, Andrew Murray, VP, International Banking and Payments at FIS shares insights on how legacy cores are no longer just an IT nuisance – they are a direct drag on profitability, efficiency, and customer trust. For banks and financial institutions, the question is no longer whether to modernize, but how to do it without disrupting “money at rest, money in motion, and money at work.”
The Hidden Cost of Legacy Systems
Mr. Murray notes that many banks delay modernization because they fear the cost, risk, and disruption of overhauling entrenched systems. Yet research from FIS and Oxford Economics shows that the status quo is already extremely expensive, with the average financial institution losing $93.6 million per year to operational inefficiencies, payment friction, human error, cyberthreats, fraud, and compliance issues. That includes $11.2 million tied to operational inefficiencies, $5.6 million to friction in payments and processing, another $5.6 million to rework and human error, and nearly $60 million associated with cyber and compliance exposure.
Beyond Technology: Transforming People and Processes
FIS emphasizes that modernization is not just a tech refresh; it’s a top-down and bottom-up transformation of processes and culture. As older technologists retire and newer developers are not equipped with deep knowledge of legacy code, banks face a skills gap that makes large-scale change even harder. Here, Mr. Murray points to generative AI and machine learning as a bridge, automating the analysis, translation, and modernization of legacy code so human developers can focus on higher-value initiatives.
Measuring the Payoff of Modernization
According to the FIS “Harmony Gap” research referenced in the article, banks that lean into fintech and AI are already seeing tangible benefits.
- 70% of surveyed banks report enhanced collaboration across the organization
- More than half cite accelerated digital transformation (54%), market expansion (56%), new customer acquisition (55%), improved engagement (51%), and higher employee productivity (50%).
Regional results vary, but across the U.S., U.K., and APAC, the pattern is clear: disciplined fintech investment yields both growth and efficiency dividends. For bank leaders still on the fence, these metrics offer a framework for building a business case and defining KPIs across customer experience, operational efficiency, financial performance, and risk management.
Partnering for a Smooth Transition
Mr. Murray closes with a reminder that core systems remains the “heartbeat” and single source of truth for the institution, even as it undergoes metamorphosis. That's why he stresses the importance of strong partners who can help institutions “run the bank” while they “change the bank,” ensuring stability, compliance, and customer experience throughout the transition.
Modernized core platforms also offer the latest innovations for payments -- including checks. While legacy cores are integrated with outdates technologies like OCR for check processing and even check fraud detection, modern cores leverage AI-powered solutions that are integrated via API. These technologies are embedded within the core itself, removing the burden of ripping out old solutions and spending countless hours and resource to integrate these solutions.
What does this mean for financial institutions? Simple. By transitioning away from legacy cores to a modernized platform, you not only able to fully reap the benefits of check automation and check fraud detection, but also unlock the potential for Intelligent Banking -- enabling your financial institution to leverage the data being created into smarter decisions, more personal experiences, and the ability to serve consumers in ways that simply weren’t possible before.
