Connecting instant systems is more than connecting APIs.

The BIS Innovation Hub's 2024 Nexus report presents a blueprint for linking domestic instant-payment systems. Developed with central banks and payment-system operators in Southeast Asia, it covers governance, oversight, commercial arrangements and technical design. This is foundational reading about the architecture of cross-border connectivity. The report describes a blueprint and implementation direction, rather than proving current availability for a particular corridor or customer.

Editorial interpretation: trace one cross-border payment through currency conversion, participant responsibilities and domestic settlement systems. Then introduce an exception and ask which party resolves it. The exercise reveals why shared rules, identifiers and recovery procedures matter as much as message delivery speed.
