Payments technologies are evolving at light speed, and so are the forces driving them. But speed alone is no longer enough. Success now depends on delivering always-on experiences while managing growing operational complexity.
Infrastructure that is merely “good” won’t support smart, holistic, and continuous modernization in a fast-moving industry. Excellence comes from modernization strategies that position technology as a strategic enabler of business transformation.
At TCF’26, the message was clear: banks that succeed in a real-time, multi-rail reality will lead by taking a forward-looking yet pragmatic approach to innovation.
Here are our key takeaways from our breakout session, Accelerating Growth in Payments at Scale.
1. Real-time expectations are redefining the market
Payments must now operate 24/7 across multiple rails, channels, and endpoints. As volumes grow and micro-payments become more common, customers expect transactions to be immediate, seamless, and reliable, whether they are paying from an account, a card, a wallet, or another digital device.
“A couple of years ago people talked about 5 billion accounts. Now they talk about 20 billion endpoints—mobile, cards, accounts,” Mick Fennell, Temenos Business Line Director – Payments, told participants at TCF’26. “All of these are either start or endpoints on a payment journey.”
As a result, the pressure is mounting for payment providers to move beyond legacy batch-based models and toward architectures built for continuous processing and real-time responsiveness.
2. Complexity is rising just as fast as volume
The ability to scale quickly is critical for banks, Electronic Money Institutions (EMIs), and all other payment providers. Scaling, however, is only part of the challenge.
An increasing number of clearing schemes, formats, investigations, and regulatory requirements must be managed in parallel, without disruption. From instant payments and RTGS to cross-border flows, ISO 20022, and structured data requirements, payment operations are becoming more demanding—and more cost-intensive.
“Sometimes we see bulk files with more than 300,000 operations,” Fennell said. “The impact on sizing, the impact on performance: it’s hugely important.” Put simply, even if customer expectations weren’t driving transformation, operational pressure alone would be.
3.Payments modernization must always be scalable, never disruptive
One of the clearest themes at TCF’26: payments modernization must evolve continuously.
It must be executed without disrupting high-volume, always-on transaction processing.
“We’re talking about progressive renovation, modernization that evolves alongside your existing estate,” Fennell said.
Payments systems cannot tolerate downtime or performance degradation. From handling real-time flows to batch files with hundreds of thousands of transactions, infrastructure must scale reliably while maintaining straight-through processing, liquidity management, and exception handling.
A rip-and-replace approach is rarely feasible. Instead, banks are taking a progressive approach to modernization; they’re evolving payment architectures step by step while running legacy and modern platforms in parallel.
Moving forward requires balancing transformation with operational continuity, in other words: modernizing processing and control without introducing risk to live payment flows.
4. The future is converged: uniting traditional and digital rails
The next wave of change is already taking shape. Stablecoins, CBDCs, and tokenized assets are pushing the industry toward multi-asset, multi-rail environments.
Banks should not treat traditional and digital payments as separate worlds. In fact, interest in cryptocurrencies like Bitcoin began on the wealth side of the banking industry, driven by client demand, not infrastructure. As speculation grew, banks were pulled into building the capabilities to support it.
This trend creates a clear opportunity: bringing payments, wealth, and new digital assets together into a single, trusted experience.
The challenge for banks is to unify traditional and emerging rails on one platform, supporting today’s payment flows while preparing for new forms of value movement.
5. Experience, and not access alone, will determine adoption
“The rails alone don’t drive adoption—it’s the experience built on top of them.” As Fennell discussed in the breakout, institutions that succeed will be those that deliver capabilities in ways customers actually use.
Strong user experiences have driven rapid adoption in markets like India and Brazil, while fragmented or poorly designed journeys have slowed it elsewhere.
For banks, this means payments modernization must be tightly aligned to usability, transparency, and speed of service. In a real-time world, experience becomes a true differentiator.
Conclusion
Payments transformation is not a one-time upgrade. It is a continuous journey shaped by scale, regulation, new rails, and rising expectations.
While each institution’s journey is different, Temenos remains a steadfast partner to banks at every stage of modernization. “This is a journey we’re going on together with our customers,” Fennell said. “We want to work with you directly to prove performance in your environment.”
Banks that act now by modernizing progressively, improving operations, and delivering better experiences will be best positioned to lead.
