PayShap and SADC-RTGS on native ISO 20022
PayShap scale, FATF remediation, and SADC-RTGS operation need an ISO 20022 overlay that is not a second switch. Nexus is that overlay for SARB.
What supervisors typically cannot see today
Instant domestic rails, SADC multi-currency clearing, and IMTO files run on three clocks. Grey-list work cannot wait on month-end.
How Nexus maps to the mandate
Target modules: ISO 20022 engine and SADC multi-currency switch overlay. Pair with PAPSS and Bank of Zambia. East & Southern Africa SI deploys.
Data residency
On-premise or designated South African cloud under SARB control.
