Quick answer

The RTGS Renewal Programme is SARB's initiative to modernise the SAMOS platform itself — moving to ISO 20022 messaging, refreshing the underlying technology, and aligning architecture with Vision 2030+. SAMOS is being renewed, not retired in the short term; the renewal is a multi-year programme running under the PEM umbrella.

Why renew SAMOS now

SAMOS has run reliably since 1998, but the technology baseline, message library, and access model reflect the architecture of that era. Global peers have already modernised their RTGS systems; the SARB's NPS Vision 2030+ called for a comparable refresh to keep South Africa interoperable, efficient, and resilient.

Programme pillars

  • Messaging: ISO 20022 native, with richer payment data.
  • Technology: modernised platform, improved resilience and recovery.
  • Access: path toward broader direct access for qualifying non-banks.
  • Interoperability: alignment with SADC-RTGS, CLS, and global RTGS partners.

Where the timeline stands

The RTGS Renewal Programme is multi-year and coordinated with the broader PEM Programme. Specific go-live milestones are revised regularly. The authoritative source is SARB's NPS Department published material.

What changes for participants

Participants will see new message formats, refreshed connectivity, updated rule books, and over time potentially a more inclusive access model. The transition is being managed in coordinated waves with parallel-running periods to manage risk.

TL;DR

  • RTGS Renewal modernises SAMOS itself, under the PEM umbrella.
  • Pillars: ISO 20022, modernised tech, broader access, interoperability.
  • Multi-year, coordinated with industry.
  • SAMOS is being renewed, not retired.

Frequently asked questions

Is SAMOS being shut down?

No. The renewal modernises the platform; it does not retire the SAMOS function.

Will participants need to re-integrate?

Yes — ISO 20022 messaging and refreshed connectivity require integration work.

Will non-banks get direct access?

Vision 2030+ contemplates broader access subject to safeguards. Concrete criteria are still under consultation.
