When the Economic Community of West African States imposed trade sanctions on Mali following the 2021 coup, the expectation was that economic pressure would restore civilian rule within months. Three years and two more coups later, Mali, Burkina Faso, and Niger have formed the Alliance of Sahel States and announced their withdrawal from ECOWAS, an unprecedented rupture in West Africa's most integrated regional bloc.

The trade implications are substantial. ECOWAS had, over decades, built one of Africa's more functional free trade areas: a common external tariff, largely open internal borders for goods and people, and coordinated monetary policy in the CFA franc zone. The departures of three member states, even relatively small ones, punch holes in that architecture.

Impact on Landlocked Trade Routes

Mali, Burkina Faso, and Niger are landlocked, making them critically dependent on coastal ports for their import-export logistics. Mali's primary trade gateway has historically been Abidjan in Côte d'Ivoire and Dakar in Senegal. Burkina Faso relies heavily on Tema (Ghana) and Abidjan. Niger uses Cotonou (Benin) and Lagos (Nigeria) as its primary ocean gateways.

ECOWAS sanctions imposed in 2022-23, and the subsequent political deterioration, disrupted these corridors. Goods destined for Bamako faced delays at Ivoirian and Senegalese borders. Freight rates on the landlocked corridors spiked as operators priced in uncertainty. Alternative routing through Togo's Lomé port surged.

New Alignments Emerge

The Sahel states have begun developing alternative trade relationships. Russian and Algerian ties have expanded for security-related imports. Moroccan and Libyan overland routes are being explored for some commodity flows. Algeria has offered preferential transit arrangements for Sahelian goods through Algerian ports.

For the remaining ECOWAS members, the crisis creates both headaches and opportunities. Nigeria and Ghana are experiencing some trade diversion, goods that previously transited to Sahelian markets are now being re-routed, and some buyers are sourcing locally rather than through disrupted supply chains. Coastal ports are competing aggressively for the Sahelian transit trade that remains.
