Banks across Asia Pacific are not short of payment infrastructure. Real-time networks, high-value systems, card schemes and cross-border linkages are largely in place. The challenge is no longer access or speed. It is the ability to coordinate and operate across these systems with consistency, resilience, and control.

These systems were built separately, at different points in time and for different purposes. As a result, payments today move across multiple rails, jurisdictions and use cases simultaneously, yet most banks still manage each system in isolation. The distinction between high-value and low-value payments is narrowing, cross-border flows are becoming more interconnected and new forms of value, including tokenised assets and digital currencies, are emerging alongside existing rails.

This fragmentation creates real operational costs. Inconsistencies in processing, visibility and data across systems erode a bank’s ability to manage liquidity, serve clients and launch new products efficiently. Every new capability added onto a fragmented stack increases legacy baggage and erodes agility. The same fragmentation that slows operations also creates blind spots in fraud detection, where siloed systems lack the cross-rail visibility needed for AI-powered fraud management to identify and respond to threats in real time, turning a control gap into a direct revenue and reputational risk.

For transaction banking and payments leaders, the priority is no longer building individual capabilities; it is running them together effectively. As leaders embark on the journey to rationalise and modernise these platforms, the strategy must incorporate fraud and risk-related impacts that tend to stall the speed of processing. Without a fraud guardrail in place, exposure will occur, leading to costly redesign and redeployment.

This roundtable brings together Transaction Banking and Payments heads to examine what multi-rail coordination looks like in practice, where progress is stalling and what needs to change operationally to move forward — drawing on global experience of banks navigating payment infrastructure consolidation across real-time, high-value, card and cross-border environments.
