Five Crises Shaping the Horn of Africa: Week of April 21, 2026

01Sudan: The Siege of El Fasher and What It Signals

El Fasher, the last major city in Darfur not under Rapid Support Forces control, is now in the final stages of encirclement. The RSF has spent the past several months tightening its perimeter, cutting supply routes, and drawing down the city's capacity to sustain a population that has swelled with displaced people from surrounding areas. Famine has been declared across parts of Darfur. Aid convoys are not reaching the city consistently. The Sudanese Armed Forces, which hold El Fasher, do not have the logistics capacity to resupply or reinforce it at scale.

The fall of El Fasher, if it comes, would represent more than a military defeat. It would complete the RSF's control of the entire Darfur region, give it a consolidated territorial base in western Sudan, and produce a humanitarian catastrophe that the international community has been warned about repeatedly but has not mobilised to prevent. The UN has estimated that over 11 million people are now internally displaced across Sudan as a whole, a figure larger than the total population of many Horn of Africa countries.

The regional dimension is increasingly visible. Chad, which shares a long and porous border with Darfur, is absorbing refugee flows that are straining its own limited resources. South Sudan is watching anxiously: both the SAF and the RSF have networks of support within South Sudanese political factions, and a decisive RSF victory in Darfur would shift those dynamics in ways Juba cannot easily manage. Ethiopia, which hosted the Jeddah talks, has lost much of its mediating leverage as the war has hardened into something that does not respond to diplomatic frameworks.

02Ethiopia: Two Crises, One Moment

Ethiopia is managing two distinct crises simultaneously, and its capacity to handle either one well is constrained by the demands of the other. The first is internal: the TPLF central committee's decision to reject the Pretoria Agreement's interim administration and back Debretsion Gebremichael as the movement's leader represents a potential unravelling of the post-war settlement in Tigray. The Pretoria Agreement was always fragile; it suspended rather than resolved the political questions that drove the war. But active TPLF rejection of the process removes even the fiction of progress and returns the situation to open-ended uncertainty. Eritrea, which was excluded from Pretoria and regards any TPLF political survival as a security threat, is watching this development with more interest than it will officially acknowledge.

The second crisis is external, though it is also partly self-created. Ethiopia's push for formalised Red Sea access has generated a sustained and organised diplomatic response from the countries most affected by it. Egypt's military engagement in Somalia, Turkey's deepened defense cooperation with Mogadishu, and Eritrea's alignment with Cairo all trace, in part, to alarm about what Ethiopian ambitions for maritime access actually mean in practice. Abiy Ahmed has framed the Red Sea question as a matter of economic necessity and historical justice. His neighbours are reading it as a signal of expansionist intent, and they are responding accordingly.

The compounding problem is that Ethiopia's domestic economy is under significant stress. Currency reform has disrupted trade patterns. Inflation remains elevated. Foreign currency reserves are insufficient to cover import needs comfortably. The government needs external investment and international goodwill at exactly the moment when its diplomatic relationships with the most consequential regional actors are fraying. That combination of internal fragility and external isolation is one that Ethiopian governments have navigated before, but it is not a comfortable position.

03Somalia: The Federal Architecture Is Under Stress

Somalia's federal structure has always been more negotiation than governance, a set of arrangements that require constant maintenance and that break down quickly when the underlying political trust is absent. That trust is currently in short supply. The federal government of President Hassan Sheikh Mohamud is in active tension with Puntland, which declared its own constitutional process in 2023 and has since operated with a degree of autonomy that stretches the boundaries of what the federal framework technically permits. Jubbaland's relationship with Mogadishu is formally intact but practically strained. The cumulative effect is a federal government whose writ does not run reliably across the territory it claims to govern.

Al-Shabaab has not gone away during the periods when Mogadishu's attention has been occupied by political disputes. The movement mounted significant offensive operations in central Somalia in recent months, retaking territory in areas where the Somali National Army had claimed gains. The pattern is familiar: government forces advance with external support, consolidate incompletely, and then Al-Shabaab recovers ground when momentum and resources shift elsewhere. The fundamental problem, that the SNA lacks the size, training, and motivation to hold territory independently of African Union mission support, has not been addressed by the current political moment.

The external dimension adds a further complication. Ethiopia's MOU with Somaliland remains a live irritant in Mogadishu's politics, even as its practical implementation remains limited. Egypt's military deployments to Somalia have given Hassan Sheikh Mohamud leverage against Ethiopia, but they have also introduced a new external actor with its own interests into an already complex political environment. Egypt is not in Somalia to help Somalia. It is in Somalia to constrain Ethiopia. Those interests may align some of the time and diverge at inconvenient moments.

04Eritrea: The Egypt Alignment Deepens

The political alignment between Eritrea and Egypt has moved this week from the ambient background of Horn diplomacy into something more visible. Egyptian officials have made repeated references to Eritrea as a partner in regional security discussions, a framing that is notable because Eritrea is not a country that invites partnership language from anyone. The PFDJ government has been careful to avoid formal treaty language, which would impose the kind of obligations it has always resisted, but the operational relationship between Asmara and Cairo is sufficiently close that the distinction between partnership and alignment has become largely semantic.

What Egypt gains from Eritrea is access to the southern Red Sea corridor and a partner that genuinely shares its concern about Ethiopian ambitions regarding the Nile and regional power projection. What Eritrea gains is more complicated: diplomatic cover, the implicit protection of association with a country that has considerably more international weight, and a counterweight to its own isolation that does not require domestic reform or political opening. For Isaias Afwerki, who has spent thirty years insisting that Eritrea can sustain its siege posture indefinitely, an alignment with Egypt is as close as his government will come to acknowledging that external relationships have value.

The cost is also real, if less visible. Eritrea's alignment with Egypt puts it in direct opposition to Ethiopia's core interests at a moment when the Ethiopia-Eritrea relationship is already cooler than at any point since 2018. It reduces Eritrea's room for maneuver if the political calculus in the region shifts. And it binds Asmara to Cairo's priorities in ways that may not always serve Eritrea's narrower interests. Alignments that are entered for defensive reasons have a way of creating their own obligations.

05Kenya: External Shock, Depleted Buffers

Kenya entered 2026 with a government that had survived the Gen Z protests of mid-2024, withdrawn the Finance Bill that triggered them, and spent the subsequent months trying to stabilise public finances without the revenue measures it had originally planned. The fiscal position was tight but not catastrophic. What the government did not have was a buffer against a new external shock. That shock has now arrived in the form of Middle East conflict-driven shipping cost increases and commodity price pressure that is feeding directly into fuel and food inflation at the retail level.

The government's move to the World Bank for emergency support is not itself a sign of crisis: Kenya has used multilateral credit facilities before and its relationship with the Bank is longstanding. What it signals is that the fiscal room that was already narrow has narrowed further. Any new financing comes with conditions, and conditions on a government that is already managing the political fallout of the 2024 protests, a Gen Z generation that is still watching, and a public that has been told repeatedly that the austerity is temporary, are politically complicated in ways that economic analysis does not fully capture.

The underlying exposure is structural. Kenya's fuel import bill is large and denominated in dollars. Its food import dependency, particularly for wheat, creates a direct transmission mechanism from global commodity markets to supermarket shelves in Nairobi. Both channels are active simultaneously. The Central Bank has limited tools to address cost-push inflation of this kind without damaging growth. The government has limited fiscal space to subsidise consumption without worsening the debt trajectory that the World Bank itself has flagged. Kenya is absorbing a shock it did not cause, with tools that are insufficient for the scale of the problem.
