NISS is Namibia’s real-time gross settlement (RTGS) system for settling individual interbank payments and retail interbank payments. The central bank highlighted NISS’s systemic role and the importance of operating it in line with international standards and best practices. Between April 2024 and April 2025, NISS processed more than 97,074 transactions with a total value exceeding NAD 1.2 trillion, and ISO 20022 was described as an internationally recognised payment messaging standard being adopted globally.
