Executive Summary

South Sudan's fragile post-war order is fracturing. The arrest and ongoing trial of First Vice President Riek Machar, intensifying clashes between government and SPLA-IO forces, and the deliberate drawdown of UNMISS from opposition-held areas have collectively pushed the country to its most unstable point since the 2018 peace agreement. The direct military intervention of Uganda, a designated guarantor of that agreement, on behalf of President Kiir's forces has further eroded the political framework that has kept large-scale civil war at bay.

The economic foundation underpinning any prospect of stability is equally compromised. South Sudan's budget depends on oil revenues for 80 to 90% of government income, a revenue base that sustained a 23.8% economic contraction in fiscal year 2025 following the Petrodar pipeline shutdown and is still operating well below pre-war production levels. Against that fiscal backdrop, roughly 80% of the population, approximately 10 million people, now requires some form of humanitarian support, a scale the government cannot meet without sustained international funding that is itself contracting.

A negotiated political solution remains the only viable path away from renewed civil war. Military resolution has no credible endpoint: SPLA-IO forces have demonstrated they retain operational capacity, Uganda's involvement risks internationalizing the conflict further, and the collapse of the Machar trial into a verdict that bars him or his party from the December 2026 elections would remove the last formal mechanism for political competition. The consequences of failure extend well beyond South Sudan's borders, into an already overstrained regional humanitarian system.
