The Pan-African Payment and Settlement System (PAPSS) is a centralized payment, clearing and settlement system for intra-African trade payments jointly developed by the AfCFTA Secretariat and Afreximbank which has been rolled out end of September 2021. It aims at streamlining and securing money flows across African borders by simplifying transactions made by using one of the 42 local currencies that are currently adopted in the continent. The system allows traders to complete these transactions in almost real-time (in less than two minutes) for a low fee. A recently published article explains in simple terms why this system has been developed and what are the advantages for African traders, along with its challenges. We will try to further simplify its content to explain the main reasons that are at the basis of the functioning of the PAPSS.
