Derived estimate — not a bank fact. DERIVED model estimate - not a bank fact. South Sudan is in conflict with no published transaction data, so no transaction figure exists. Under BRASA's dark-nation rule it is modelled as an average African nation: population (11.5M) times Africa's mean mobile-money throughput per capita (US$1,539, the average across the 22 nations with published or modelled mobile-money data) = ~US$17.7B. A neutral placeholder for where the country would sit if it were a typical, peaceful African nation - not a recorded total and not a claim about its actual flows. A simulator input.
