Interoperability between payment systems across borders
The Bank for International Settlements (BIS) published a paper on cross-border payment system interoperability. It illustrates the public and private sector options using four stylized models, ordered in increasing complexity and cost but also greater efficiency – a single access point, bilateral link, hub and spoke or a common platform (see below). The BIS Innovation Hub is putting theory into practice with several innovative projects to foster interoperability across the four stylized models.
