The verdict

Judgement

South Sudan holds a poor hand and is playing it about as badly as a state can. It is the world's youngest country, with about 12 million people, oil that can leave only through a pipeline across war-torn Sudan, and extreme poverty that rose to 87% in 20251,6. Its rulers have spent its money on the presidency rather than the state: civil servants were owed 8 to 13 months' pay by January 2026, inflation reached 234%, and the 2018 peace deal has largely collapsed, with the first vice-president on trial for treason6,9,13. It is due to hold its first election on 22 December 202611; whether that vote happens, and whether the country slides back into the war that killed about 400,000 people, will decide everything else10.

Where this lens is weakest: The LKY lens explains South Sudan's failure plainly: a state whose leaders loot its one resource and fight each other cannot provide order. Where it risks misleading is in assuming a strong man could fix it. Power here is already concentrated in the president, who has suspended his rival and rotates senior officials frequently13,6, and that concentration has produced less order, not more. The lens also has little to say about a conflict fought along largely ethnic lines10, which needs political settlement more than command. Data on almost everything is poor or old, so several scores rest on thin evidence; the scale of the failure is not in doubt.

Geography

2 Weak Stable High confidence

What does the map enable, and what does it threaten?

The map gives South Sudan oil and a trap. Oil was found in Unity State in 19788, and it is the economy's mainstay, but it can only be exported through a pipeline across Sudan: when that pipeline shut in FY25, output fell sharply and the economy contracted6. Production recovered to 157,000 barrels a day in early FY26 under a security agreement to protect Sudan's export infrastructure6, which now runs through a country at war. Its border with Sudan includes disputed ground: an arbitration in 2009 placed the Heglig oil field in the north, and the Abyei area remains contested8. Climate shocks threaten its farming6. Oil that the country does not control the route for.

People

1 Critical weakness Declining Medium confidence

Is the population growing, skilled and staying?

The population is about 12.4 million, with a median age of about 191,2. Their condition is among the worst anywhere. Extreme poverty rose from 84% in 2024 to 87% in 20256. In 2026 more than 10 million people, two-thirds of the population, are projected to need humanitarian assistance, and education and health systems are fragile6. In Jonglei, nearly 60% of the population is expected to face crisis-level hunger during the rainy season12. The ILO's modelled unemployment rate of 12.4%5 is dated and says little. A people the state has left to survive on aid.

Layer 2 · Multipliers

Culture

1 Critical weakness Stable Medium confidence

What habits does the society reward?

The institutional habits are among the weakest in the world. South Sudan scored 9 on Transparency International's 2025 index, ranking 181st of 1827. Public money flows outside the budget: significant off-budget spending, financed by banks including the central bank, masks a much larger deficit than reported6. Political disputes have repeatedly been settled by force: Kiir sacked his cabinet and vice-president in 2013, and civil war followed within months8. Survey data on trust and work norms was not gathered, hence medium confidence. This score is about institutions and social habits, not about any group.

Leadership

1 Critical weakness Declining Medium confidence

Who rules, how are they chosen, and are they competent?

Judged by deeds, President Salva Kiir's government has failed at the basics. The deficit widened to 6.7% of GDP in FY25, driven mainly by spending by the Ministry of Presidential Affairs, while civil servants went 8 to 13 months unpaid6. Inflation reached 234%6. The World Bank lists frequent rotation of senior officials among the main risks6. In March 2025 security forces placed First Vice-President Riek Machar under house arrest; in September he was charged and suspended from office13. The 2018 peace agreement has largely collapsed9. The government has promised elections in December 2026 after years of delay11. A leadership that has turned the state into a means of keeping power.

Order

1 Critical weakness Declining High confidence

Is there rule of law, low corruption and predictability?

Order has broken down across much of the country. Fighting between government forces and opposition fighters loyal to the SPLA-IO, with allied White Army fighters, spread in Jonglei in early 202612. The army ordered civilians and UN staff out of three counties ahead of its offensive10, and a senior commander urged troops to spare no lives12. More than 230,000 people had been displaced since December 2025 by February 202612. The government insists there is relative peace apart from pockets of insecurity, while observers warn of a return to full-blown conflict9. Aid agencies are frequently attacked9. A state that cannot protect its people from its own army.

Cohesion

1 Critical weakness Declining Medium confidence

Where are the fault lines, and how stable are they?

South Sudan has never been one nation. Its 2013–18 civil war between Kiir's forces and those loyal to Machar was fought along largely ethnic lines and cost about 400,000 lives10. The 2018 peace deal that ended it has largely collapsed9. The fighting of 2026 pits the same camps against each other, with Machar's forces and allied White Army fighters against government troops12. The case against Machar centres on an attack by a Nuer youth militia on an army base at Nasir in March 202513. A country held together, if at all, by the memory of a common war against the north.

Relevance

1 Critical weakness Stable Medium confidence

Why does the world need this country?

The world needs South Sudan very little. The IMF puts its 2026 GDP at about US$8bn3. Its oil, about 157,000 barrels a day in early FY266, is small by world standards. It matters mainly as a humanitarian burden and a risk to its region: the war in Sudan, entering its third year, presses on its economy and its people6. It hosts a large UN mission, ordered out of parts of Jonglei in 202610. Noticed for its crises, not its weight.

Layer 3 · External game

Interests

Described, not scored

What does it need, want and fear?

Need: oil flowing through Sudan's pipeline, which depends on a security agreement amid Sudan's war6; and money to pay civil servants owed months of salary6. Need: food and aid for the two-thirds of the population who require it6. Want, for the government: an election on its terms on 22 December 2026, with Machar on trial and under house arrest11,9; and victory over the SPLA-IO in Jonglei and Upper Nile10. Fear: a return to full-scale war9; disruption of the oil route through Sudan6; and the loss of aid as donors pull back6.

Balance of power

2 Weak Stable Low confidence

Who are its patrons, rivals and hedges?

South Sudan has no balance of its own; it survives on outside help. Uganda's troops intervened on the government's side when civil war broke out in 20138. Its economy depends on Sudan, through whose territory its oil must pass, and on a security agreement to protect that route6. Ethiopia has hosted its peace talks8. The World Bank and other donors fund much of its services6. The UN has a large mission on its soil, which the army has ordered out of conflict areas10. Allies enough to survive, not to prosper.

Strength

1 Critical weakness Stable Low confidence

Can it deter, or does it depend on others?

South Sudan's forces are used mainly against its own people. SIPRI puts military spending at 3.42% of GDP in 20254, a high share of a tiny economy3. The army has not defeated the opposition: SPLA-IO and White Army forces made gains against government troops in Jonglei in early 202612. When civil war broke out in 2013, Ugandan troops intervened on its side8. The state cannot pay its own civil servants, who were owed 8 to 13 months' salary by January 20266. Data on readiness is poor, hence low confidence. An army that cannot win its own war.

Trajectory

1 Critical weakness Declining Medium confidence

Rising, stagnant or declining, and how fast?

Judged by results, South Sudan is going backwards. The economy contracted in FY25 when oil output fell after the pipeline shutdown6. The IMF expects a rebound of 10.5% in 2026 as oil recovers3, but that restores lost ground rather than building new. Extreme poverty rose to 87% in 2025, inflation reached 234%, and the official exchange rate depreciated by 198%6. Fighting resumed in Jonglei, and the peace deal has largely collapsed12,9. The transitional period runs to February 2027, with elections promised for December 20266,11. A country slipping back towards war.

Power map

History that shaped it

14 events · facts cited, meaning is judgement
  1. 1899–1955

    Anglo-Egyptian rule

    From 1899 to 1955 South Sudan was part of Anglo-Egyptian Sudan, under joint British-Egyptian rule8.

    Why it matters Colonial rule tied the south to Khartoum without building a state in it.

  2. 1962

    First civil war

    A civil war led by the southern separatist Anya Nya movement began against the north in 19628.

    Why it matters War, not administration, became the south's main experience of politics.

  3. 1972

    Addis Ababa accord

    In 1972 a peace agreement signed in Addis Ababa conceded a measure of autonomy for southern Sudan8.

    Why it matters Autonomy brought a decade of peace that ended when Khartoum took it back.

  4. 1978

    Oil discovered

    Oil was discovered in Unity State in southern Sudan in 19788.

    Why it matters Oil made the south worth fighting over, and later the new state's only real income.

  5. 1983

    Second civil war

    Fighting broke out again in 1983 under John Garang's SPLM after President Numeiri abolished the south's autonomy8.

    Why it matters The SPLM's war forged the movement that would rule the new state, with its military habits.

  6. 2005

    Comprehensive Peace Agreement

    In January 2005 the Comprehensive Peace Agreement ended the civil war, granting autonomy and a referendum on independence in six years8.

    Why it matters It gave the south self-rule and a path to statehood, under former rebels.

  7. 2005

    Garang dies; Kiir succeeds

    In August 2005 southern leader John Garang was killed in a plane crash and was succeeded by Salva Kiir Mayardiit8.

    Why it matters Kiir has led ever since, and the state has been shaped by his rule.

  8. 2011

    Independence

    South Sudanese voted for full independence in January 2011, and the country became independent on 9 July 20118.

    Why it matters It became the world's youngest nation with almost no institutions of its own.

  9. 2012

    Heglig and the oil shutdown

    In April 2012 South Sudanese troops briefly occupied the Heglig oil field before being repulsed; a dispute over fees shut down oil production for more than a year until March 20138.

    Why it matters It showed that the new state's income depended on its old enemy's pipeline.

  10. 2013

    Civil war

    Civil war erupted in December 2013 when President Kiir accused his former vice-president, Riek Machar, of plotting to overthrow him; Ugandan troops intervened on the government's side8.

    Why it matters The leaders' feud became a national war, and the state never recovered.

  11. 2016

    Peace collapses

    Riek Machar returned to Juba in April 2016 as first vice-president in a unity government, but was sacked in July after further conflict and went back into exile8.

    Why it matters Power-sharing without trust failed, a pattern repeated since.

  12. 2018

    Revitalized peace deal

    The Revitalized Agreement on the Resolution of the Conflict was signed in September 2018, and a Transitional Government of National Unity formed in February 20206.

    Why it matters It brought relative stability but left both armies and both leaders in place.

  13. 2025

    Machar arrested

    In March 2025 security forces placed Riek Machar under house arrest after an attack on an army base at Nasir; in September he was charged and suspended as first vice-president13.

    Why it matters Removing the rival undid the peace deal's core bargain.

  14. 2026

    War in Jonglei

    Fighting between government forces and the SPLA-IO spread in Jonglei in early 2026, displacing more than 230,000 people since December 202512.

    Why it matters The country is sliding back towards the war the peace deal was meant to end.
