Who Builds the Bridge Between National Payment Schemes; and Who Owns the Toll?

National instant payment schemes are proliferating around the world, yet most remain valuable only within their own borders. As domestic networks mature, the next source of value lies not in individual schemes, but in the bridges that connect them.

This session explores the emerging cross-border interoperability layer: who is building it, how common messaging standards and technical frameworks make it possible, and how governance, costs, revenues, and risks are shared among the parties involved. The discussion will examine the different models being adopted globally, from bilateral connections to multilateral networks and shared infrastructure platforms.

Participants will leave with a clearer understanding of where payment interoperability is succeeding in practice, what challenges remain, and the trade-offs between different connectivity approaches.

One of the central questions the panel will explore is: when one country's instant payment scheme needs to communicate with another's, who builds the bridge, and who owns the toll?
