WAEMU: A Community Law Framework Structuring Business in West Africa
Created by the Dakar Treaty of 10 January 1994 and built upon the pre-existing West African Monetary Union, WAEMU was conceived not merely as a monetary arrangement, but as a broader project of economic and legal integration (WAEMU Treaty, Arts. 2 and 4). It brings together eight Member States — Benin, Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Mali, Niger, Senegal and Togo — within a common institutional framework designed to promote competitiveness, economic convergence and a harmonised legal environment across the regional market (WAEMU Treaty, Art. 4(a), (b) and (e)). Its stated ambition is the creation of an integrated economic space in which the free movement of persons, goods, services, capital and factors of production can operate effectively (WAEMU Treaty, Art. 4(c)).
Recent political developments, however, call for a degree of nuance in relation to Burkina Faso, Mali and Niger. Current official WAEMU documentation continues to list all three among the Union’s Member States. At the same time, following the interruption of constitutional order in Mali, the Conference of Heads of State and Government endorsed ECOWAS sanctions, imposed additional economic and financial sanctions, suspended Mali from WAEMU bodies and institutions, and suspended financial assistance from WAEMU financing institutions. In Niger, the official materials reviewed do not show a comparable formal suspension from WAEMU bodies and institutions, but they do show exceptional BCEAO prudential measures in 2024 relating to the treatment of Nigerien sovereign securities, which were lifted in April 2025 after the normalisation of the State’s interventions on the regional market
Its institutional structure reflects that ambition. The Union is organised around the Conference of Heads of State and Government, the Council of Ministers and the Commission, while judicial oversight is exercised by the Court of Justice and the Court of Auditors; the BCEAO and the BOAD, for their part, operate as autonomous specialised institutions within the Union framework (WAEMU Treaty, Arts. 16, 38 and 41). Unlike OHADA, WAEMU does not establish a single body of uniform business law. Its legal order is instead built through Community instruments — notably regulations, directives and decisions — whose legal effects are defined with precision by the Treaty: regulations are binding in their entirety and directly applicable in all Member States, directives bind Member States as to the results to be achieved, and decisions are binding on their designated addressees (WAEMU Treaty, Arts. 42 and 43).
In that respect, WAEMU may usefully be read alongside CEMAC in Central Africa gathering the Central African Republic, Cameroon, Gabon, Equatorial Guinea, Chad and Congo : both regional groupings combine a common monetary area, community institutions, specialised regional financial bodies and a supranational layer of rules that materially affects banking, payments, foreign exchange and cross-border economic activity, even if the relevant institutions and legal instruments differ in structure and scope. In CEMAC, this regionalisation is reflected in particular in the Convention harmonising the regulation of credit institutions, in the supervisory role exercised by COBAC, and in Community regulations governing payment systems, means of payment and payment services.
The substantive reach of WAEMU law extends in particular to tax harmonisation, competition law, the free movement of persons, the right of establishment, the freedom to provide services, and the gradual organisation of the common market (WAEMU Treaty, Arts. 4(e), 76(c)-(e), 88 to 90, and 91 to 93). In customs matters, WAEMU has put in place a genuine customs union based on the elimination of internal customs barriers, a Common External Tariff, Union customs legislation and Community rules of origin (WAEMU Treaty, Arts. 76(a)-(b), 77 and 82; Regulation No. 02/97/CM/UEMOA on the Common External Tariff, as amended; Regulation No. 09/2001/CM/UEMOA adopting the Community Customs Code; Additional Protocol No. III/2001 instituting the rules of origin, as amended by Additional Protocol No. I/2009). For businesses and their advisers, this means that import structures, tariff treatment, origin qualification, customs compliance and the circulation of goods within the Union must be assessed against a binding Community framework rather than by reference to domestic law alone.
The monetary and foreign-exchange dimension is equally important. Because WAEMU rests on a common monetary area, the Franc CFA (XOF), legal analysis frequently intersects with the rules governing external financial relations, including cross-border payments, transfers, foreign-currency transactions and certain transactions involving non-residents (WAEMU Treaty, Arts. 4(c), 76(d) and 41; Regulation No. 06/2024/CM/UEMOA on the external financial relations of the Member States; Art. 35 of that Regulation, repealing Regulation No. 09/2010/CM/UEMOA). In practice, this adds a distinct regulatory layer to cross-border financing, repatriation issues, payment flows and foreign investment operations within and outside the Union
This monetary and foreign-exchange framework is complemented, within the WAEMU/WAMU area, by a uniform banking law applied across the Member States. That law is built around familiar banking concepts: receiving funds from the public, granting credit, providing means of payment, and requiring prior authorisation to carry out banking business (Uniform Banking Act, Arts. 2, 6, 7 and 13).
A comparable framework exists in CEMAC, where regional banking regulation relies on much the same concepts (CEMAC Banking Harmonisation Convention, Arts. 4, 6, 7 and 12). In both regions, these notions remain close to those found in French banking law, including the definition of banking operations and the rule that only duly authorised institutions may conduct banking business (see, for example, Articles L.311-1 and L.511-5 of the French Monetary and Financial Code). Related areas such as payment instruments, foreign-exchange transactions and prudential supervision are similarly familiar from a French-law perspective.
