Floods and quakes displace thousands—while Sudan’s refugee crisis strains Chad’s border security and jobs

In southern Sudan, the UN reports that floods have displaced 168 families and damaged 271 homes, with people fleeing around 10 villages in Abu Kershola in South Kordofan and taking shelter in open areas. The report frames the displacement as immediate and localized, but it also signals a broader vulnerability in rural settlements where housing and basic services are easily overwhelmed. In Indonesia, a powerful earthquake in East Nusa Tenggara has driven a rapidly worsening humanitarian picture: the death toll has risen to 111 and more than 176,000 people are displaced. Officials cited by Anadolu also described 8,193 aftershocks, underscoring ongoing instability that can delay rescue operations and increase secondary damage. Taken together, the cluster highlights how climate-linked flooding and seismic shocks can quickly become political and economic stress multipliers, especially where governance capacity is already constrained. For Sudan and Chad, SIPRI’s research focuses on the Chad–Sudan border region, arguing that refugee women and girls face significant safety threats and that existing protection measures are inadequate. That matters geopolitically because refugee flows can intensify border insecurity, strain local labor markets, and raise the risk of social fragmentation—conditions that can be exploited by armed actors or criminal networks even without a single “headline” confrontation. Indonesia’s disaster, while not described as a geopolitical contest, still carries strategic weight for regional stability and fiscal planning, as large-scale displacement can pressure public budgets and infrastructure priorities. Market and economic implications are likely to be concentrated in humanitarian logistics, insurance, and local supply chains rather than global commodity benchmarks. In Sudan and Chad, displacement and damaged housing can disrupt agricultural cycles and increase demand for food, water, and shelter materials, typically lifting prices in affected areas and raising costs for aid delivery; the near-term effect is more “micro-inflation” and procurement pressure than a national macro shock. In Indonesia, the scale of displacement and the volume of aftershocks raise the probability of localized disruptions to construction, transport, and utilities, which can affect regional construction inputs and logistics rates; the direction is upward for insurance and reconstruction-related costs. Currency and sovereign risk effects are not explicitly quantified in the articles, but the combined pattern of displacement and infrastructure stress tends to increase fiscal uncertainty and can widen risk premia for countries with limited buffers. What to watch next is whether displacement becomes protracted and whether protection gaps translate into measurable increases in violence, exploitation, or cross-border tensions. For Sudan–Chad, key indicators include the number of newly arriving refugees at border locations, reported incidents targeting women and girls, and whether aid agencies can scale education, employment support, and land access programs. For Indonesia, monitoring should focus on aftershock intensity trends, damage assessments to critical infrastructure, and the government’s ability to maintain shelter and health services as displacement counts rise. Trigger points for escalation differ by context: in Sudan–Chad, a deterioration in safety and access to livelihoods would raise the risk of longer-term instability, while in Indonesia, a further spike in casualties or infrastructure failures would accelerate emergency spending and potentially slow economic activity in affected provinces.

Geopolitical Implications

• 01

  Refugee integration failures can become a border security and governance stressor.

• 02

  Protection gaps for women and girls raise the risk of exploitation and long-term instability.

• 03

  Disaster-driven displacement can force fiscal reprioritization and disrupt local economic activity.

Key Signals

• —Rising counts of newly displaced families and refugees at border locations.
• —Documented incidents targeting refugee women and girls and effectiveness of scaled protection.
• —Aftershock frequency trends and infrastructure damage assessments in East Nusa Tenggara.
