2026 is shaping up to be the turning point for digital banking in Latin America. Not because of any single cause, but because of three forces converging at once, forces that have been building for some time: mounting regulatory pressure, increasingly aggressive fintech competition, and a need to modernize the core that can no longer be put off.
Regulators across the region have been demanding greater traceability, stronger operational resilience and real-time audit capability. That changes the nature of the problem: modernizing the banking core has gone from an internal efficiency decision to a business requirement. A legacy system that cannot expose data in an auditable way, or that takes weeks to adapt to a new regulation, is now a concrete regulatory risk, not a technical inconvenience.
At the same time, fintech competitors, agile, cloud-native, without two decades of technical debt weighing them down, raised the bar on what customers expect from their bank: accounts opened in minutes, products launched in weeks rather than years, experiences that feel current. Traditional banks are not only competing with other banks; they are competing with expectations set by companies that started from scratch.
The third factor is quieter but just as decisive: modernization approaches have matured to the point where banks no longer have to choose between sticking with the legacy system and rewriting everything at once. Incremental strategies, moving services over gradually, keeping the old system running in parallel while the new one gains ground, have turned core modernization from a leap of faith into a process that can be planned, measured and, if necessary, paused midway.
These three forces are converging right now, and that is what makes 2026 different: banking modernization is not a new topic; it has simply stopped being optional. A bank without a concrete plan to modernize its core today is not choosing to maintain the status quo; it is choosing to take on regulatory and competitive risk that is increasingly hard to justify.
At Sagant, we have spent years working with organizations on core system modernization, always on the same premise: there is no room for trial and error when critical operations and sensitive data are involved. Modernization that works is not the boldest plan on paper; it is the one executed methodically, step by step, without betting business continuity on a single move.
2026 will not be the year every bank in the region finishes modernizing its core. It will be the year the gap between those that started on time and those still postponing becomes impossible to ignore.
