In January 2024, a tectonic shift occurred in West African geopolitics. Three nations—Mali, Burkina Faso, and Niger—made an announcement that many international observers initially dismissed as a bluff: they were withdrawing from the Economic Community of West African States (ECOWAS).
Since 1975, ECOWAS had been the bedrock of regional integration, providing shared trade rules, open borders, and a collective security architecture closely aligned with Western powers. For decades, leaving ECOWAS was considered unthinkable. Yet, by January 29, 2025, the unthinkable became official. Nearly half a century of integration was severed overnight, signaling the birth of a new political bloc: the Alliance of Sahel States (AES).
The Path to the Breakaway
The withdrawal was not a sudden impulse but the climax of a year-long “test of resolve.” In early 2024, all three nations were already pariahs within ECOWAS, ruled by military governments that had seized power via coups. ECOWAS had responded with heavy-handed sanctions: freezing assets, closing borders, and, in Niger’s case, cutting off the electricity supply from Nigeria.
The regional message was: Return to civilian rule or face isolation.
Instead of yielding, the three nations doubled down. Under ECOWAS rules, withdrawal takes one year. During that window, the AES countries didn’t negotiate for concessions; they built a parallel system.
-
September 2023: They signed a mutual defense pact.
-
2024: They formalized the AES name and began issuing AES passports, replacing ECOWAS travel documents.
-
Monetary Shift: They opened talks on new financial institutions, signaling a potential exit from the CFA Franc system.
Why the West Sees the AES as a Geopolitical Threat
If these countries are among the poorest on Earth and face internal insurgencies, why does their breakaway trigger such alarm in Washington and Paris? The answer lies in the dismantling of a specific system of control.
1. The End of the “Gatekeeper” System
For decades, ECOWAS served as the political infrastructure that made Western intervention in Africa legitimate. When a crisis occurred, ECOWAS spoke first, and the West followed. By leaving ECOWAS, the AES countries removed the “leverage point.” The West no longer has a regional body through which it can legally and diplomatically enforce its will on these three states.
2. The Collapse of the Security Buffer
The Sahel was long treated as a “front line” in the War on Terror. France stationed thousands of troops, and the U.S. built multi-million dollar drone bases (notably in Niger) to monitor jihadist movements. However, after a decade, the results were dismal: insecurity worsened and violence spread.
The AES governments reframed foreign troops not as protectors, but as permanent, unaccountable fixtures. By expelling French and American forces and turning toward new partners (like Russia), the AES has physically closed a strategic corridor the West relied on for regional surveillance.
3. Monetary Sovereignty and the CFA Franc
Perhaps the most enduring instrument of French control is the CFA Franc. This currency system requires 14 African nations to keep 50% of their foreign reserves in the French Treasury.
-
Extraction: Critics argue the system encourages capital flight, allowing French corporations to repatriate profits with zero exchange risk.
-
Lack of Autonomy: France maintains representatives on the boards of African central banks, effectively influencing monetary policy without holding capital shares.
The AES’s move to question this system is a direct threat to French economic stability and the precedent of “monetary sovereignty.”
4. Control of Critical Resources
The Sahel sits atop mineral wealth essential for the global energy transition.
-
Uranium: Niger has provided 15-20% of France’s nuclear fuel needs for decades. Historically, Niger received only about 5.5% of the market value in royalties.
-
Nationalization: The AES countries have moved to nationalize industries like gold mines and water services previously managed by Western firms.
-
Supply Chains: By controlling this territory, the AES controls future transit corridors for lithium and rare earth minerals.
The “Contagion” of Sovereignty
The real fear in Western capitals is not necessarily the collapse of these three states, but their survival.
The West operates on the assumption that there is “no alternative” to its security and financial systems. The AES challenges this by simply existing. If three landlocked, impoverished nations can survive sanctions and coordinate their own security without Western permission, other African nations might begin to ask: Who does regional integration really serve?
Western rhetoric has shifted from dismissal to defense. The U.S. has imposed travel restrictions, and intelligence briefings now warn of the Sahel “slipping out” of the post-Cold War order. This isn’t just about a military contest; it’s about the loss of a monopoly on legitimacy.
Conclusion: A World of Choice
By early 2026, the AES has survived its first year of official independence. While they still face massive hurdles—rising trade costs, active insurgencies, and limited fiscal space—the alliance has already succeeded in making the “unthinkable” a reality.
The AES does not need to become a superpower to be a threat; it only needs to persist. Its existence proves that alignment with the West is no longer a guaranteed requirement for statehood. To millions in the Sahel, this isn’t isolation—it feels like a sovereignty that was delayed for 60 years, finally being claimed.
The question for the West is no longer how to “fix” the Sahel, but how to adapt to an Africa that is finally starting to choose its own path, its own risks, and its own partners.
