Summary

The advent of the oil sector once offered some stability, but the arrest and trial of Riek Machar threaten the 2018 peace deal, and exports via Sudan have been repeatedly disrupted by its civil war. A weak governmental structure and arrears compound the risks. Outlook amended from Uncertain because the collapse of the peace process and export disruption point clearly to deterioration. Outlook: Negative. Risk premia raised from 7.5% to 12.5%.

The arrest and trial of First Vice-President Riek Machar in 2025 has threatened to unravel the 2018 peace deal, with elections nominally due in December 2026. The FCDO advises against all travel, and US and UK guidance cite conflict, corruption and arrears. The EIA notes that South Sudan depends almost entirely on oil exports through Sudan, which have been repeatedly disrupted by Sudan's civil war.
