Priya Jaiswal is a titan in the world of market analysis and portfolio management, bringing a wealth of knowledge on how international business trends dictate the success of modern financial institutions. Today, we sit down to discuss the critical evolution of core banking systems and why shifting away from rigid legacy platforms is no longer a luxury but a survival tactic. With decades of industry foresight, Priya provides a deep dive into the mechanics of real-time infrastructure and the strategic necessity of digital transformation in an era of rapid technological disruption.
Many financial institutions still operate with fragmented technology estates where cards, lending, and payments sit on separate legacy systems. How does this fragmentation hinder a bank’s ability to truly understand its customers?
When you have cards, lending, and core banking living in different silos, you are essentially looking at a customer through a cracked mirror. Each piece of data is typically processed in batches, meaning by the time a bank sees a transaction or a change in behavior, the actual moment of influence has already passed. Consolidating these capabilities onto a single platform allows for a unified customer view where data isn’t just a record of the past but a live feed of activity. This shift is crucial because it reduces the massive weight of operational complexity that keeps banks from moving fast enough to compete with fintech challengers. By finally bridging these gaps, institutions can unlock rich customer insights that were previously buried under layers of outdated, disconnected code.
The prospect of replacing a core banking system is often seen as a “heart transplant” for a bank. How are modern platforms changing that narrative through incremental modernization?
The fear of a total system overhaul often paralyzes bank leadership, but the advent of API-native and cloud-native platforms allows for a much more surgical and safe approach. Instead of a high-risk “rip and replace” strategy that threatens the entire operation, banks can now modernize incrementally by upgrading specific functions without disrupting their daily business. This is exactly why the acquisition of Pismo by Visa in 2024 was such a landmark move; it combined a ground-up real-time infrastructure with a massive global security reach. This method provides a vital safety net for institutions, allowing them to evolve their foundations while still keeping the lights on for their millions of customers. It is about building the future on top of the present, rather than burning the bridge behind you and hoping for the best.
We are seeing a massive shift toward real-time banking. Beyond just faster transactions, what does this move to an event-driven architecture mean for the daily experience of a banking customer?
Customers today have zero patience for the traditional batch processing delays that used to be the industry standard for decades. They want instant gratification and highly personalized experiences that feel like they were designed specifically for them in that very second. Using an event-driven architecture, banks can sense customer behavior as it happens and deliver contextual offers or loyalty rewards at the precise moment they matter most. It is the difference between getting a discount notification while you are actually standing in a store versus receiving a generic email three days after you have already left. This level of intimacy and speed is what defines the next generation of financial services, turning banking from a dull utility into a proactive partner.
As financial institutions look to expand internationally, how can they maintain a consistent global strategy while navigating the complex web of local regulations and payment schemes?
Balancing global consistency with the gritty reality of local flexibility is perhaps the greatest challenge for any expanding bank in the modern age. Each market comes with its own unique set of regulatory requirements and payment schemes that can feel like a labyrinth to navigate without the right tools. The smartest way forward is utilizing a single global software platform that employs specialized localization layers to absorb those country-specific rules. This allows a bank to scale across borders without the massive overhead of maintaining dozens of separate, disconnected core systems in every region. It creates a streamlined operational model where the core stays stable and secure, but the edges are flexible enough to respect local laws and customer expectations.
The intersection of payments and core banking is becoming increasingly blurred with the rise of tokenized assets and programmable money. How should banks prepare their infrastructure for this convergence?
We are entering an era where tokenized assets, stablecoins, and real-time settlement are becoming the new baseline for global commerce. To stay relevant, banks must ensure their infrastructure is ready to support 24/7 settlement and entirely new products built around these digital assets. This isn’t just about adding a new feature to an old system; it is about a fundamental rewiring of how money moves and is accounted for in a digital-first world. Modern platforms are designed to be interconnected from day one, allowing for the programmable logic required for sophisticated, modern finance. If the foundation isn’t built for this level of agility, the bank will find itself locked out of the most lucrative and innovative markets of the future.
With the rise of agentic AI—where autonomous agents make purchases and book services on behalf of humans—what are the most significant security and fraud challenges that legacy systems are ill-equipped to handle?
Agentic commerce introduces a world where a machine is researching, booking, and paying for services without a human ever pressing the final “buy” button. This shift creates a massive authentication and security headache because traditional fraud detection was built to monitor human patterns, not autonomous AI agents acting on a user’s behalf. Legacy systems simply do not have the speed or the structural flexibility to handle the sheer volume and velocity of these AI-driven financial activities. We need an infrastructure that can authenticate these agents in real-time while maintaining a high wall against sophisticated new types of automated fraud. Without a modern core, the risks associated with this level of automation could easily overwhelm an institution’s existing defenses.
What is your forecast for the future of banking over the next decade as technologies like quantum computing and AI continue to converge?
Over the next ten years, I expect to see a total transformation where modernization is no longer treated as a technical project but as the core strategic business priority for every successful bank. We will see a convergence of AI, tokenization, and modern payment orchestration that will make banking nearly invisible and fully integrated into our daily digital lives. The winners will be the institutions that have spent the last few years shedding their legacy weight and embracing cloud-native agility to adapt to shifting regulations. Drawing on over 30 years of industry evolution, I believe the move toward real-time, programmable money will be the defining shift of our generation. Banking will become less about managing accounts and more about orchestrating value in a hyper-connected, autonomous global economy.
