Defending the Guinean franc allows the government of Guinea-Bissau to present monetary policy as a direct extension of national sovereignty. The state retains the ability to issue currency, manage reserves, adjust liquidity, and respond to internal pressures without depending on a regional authority.

This margin does not eliminate economic problems, but it keeps key decisions within national institutions. Monetary sovereignty also has political value for a government seeking to assert its own economic agenda. By linking the national franc to the protection of the population's interests, political power transforms a technical choice into a message of authority.

The central bank and the government retain their instruments, while regional integration is contingent upon the presentation of concrete advantages and lasting guarantees. However, maintaining a national currency does not ensure stability, confidence, or purchasing power.

The ability to act on one's own initiative depends on fiscal discipline, central bank credibility, available reserves, and the productive structure. A state can manage its currency and still remain vulnerable to inflation, foreign exchange shortages, and dependence on exports.

The central issue lies in the quality of autonomy, not just its existence. A national monetary policy can protect domestic priorities, but it can also be subject to the immediate calculations of political power. Without institutions capable of limiting opportunistic decisions, proclaimed sovereignty risks serving the government before responding to the economy, businesses, and citizens.

For Guinea-Bissau, the choice preserves national instruments while the ECO remains surrounded by uncertainty. For ECOWAS, the position creates a precedent: a state can participate in the preparation of the common currency and refuse its adoption. This possibility weakens the region, increases the bargaining power of members, and transforms integration into an accession discussed on a case-by-case basis.

A single currency requires more than a decision by heads of state. It demands economies capable of adhering to common rules on inflation, public debt, deficits, reserves, and government financing. In West Africa, these conditions remain unevenly distributed among countries with profoundly different productive structures, fiscal capacities, and external vulnerabilities.

Nigeria possesses an economic and demographic weight that no other member can balance in isolation. Ghana faces its own pressures regarding debt and currency, while several countries use the CFA franc within an organized monetary union.

Guinea-Bissau maintains the Guinean franc and an economy dependent on mining, whose main commercial relations extend beyond the region's borders. These differences make it difficult to define a monetary policy capable of serving all participants simultaneously. An interest rate suitable for reducing inflation in one economy may limit credit in another.

Budgetary discipline, necessary to protect the regional currency, can diminish a government's ability to finance the most urgent public services, infrastructure, and social responses. The problem becomes more sensitive when a crisis affects only a group of countries.

Without stabilization funds, transfer mechanisms, and assistance rules, the costs may fall on populations outside the decisions responsible for the imbalance. The common currency brings national risks closer together and obliges governments to assume responsibilities that previously remained within their borders.

Guinea-Bissau's hesitation exposes this fragility. Before abandoning the franc, the country is seeking to understand how its reserves, mining revenues, and budgetary margin will be protected. The gradual adoption foreseen by ECOWAS could allow the initial entry of countries that meet the criteria, but it will also create different levels of participation within a project presented as a common instrument.

A monetary union depends on trust between states because each government relinquishes part of its decision-making power to common institutions. This trust requires known rules, credible data, fulfilled commitments, and accountability mechanisms.

ECOWAS is going through a period of political strain that has made it more difficult to convince its members to transfer new powers to the regional level. The departure of Mali, Burkina Faso, and Niger has reduced the bloc's political dimension and shown that integration can regress when governments challenge regional authority.

Guinea-Bissau occupies a different position because it has not abandoned ECOWAS and remains involved in its technical mechanisms. However, the decision to protect the national currency reveals limited confidence in the bloc's ability to organize a balanced monetary authority. Participating in the ECO team allows one to monitor negotiations, evaluate rules, and defend national interests.

Trust also depends on institutional stability within each state. Civilian governments, military transitions, fragile parliaments, and central banks with varying margins will all have to adhere to the same norms. When internal legitimacy is challenged, it becomes difficult to ensure that the commitments made by one administration will be respected by the next.

ECO therefore needs a more solid political foundation than a launch timetable. States need to trust the issuing institution, the distribution of votes, the management of reserves, and the application of sanctions.

Without an architecture accepted by the participants, every decision regarding interest rates, liquidity, or debt could turn into a dispute between national sovereignty and regional authority.

The dispute goes beyond economics because it involves the direction of the monetary institution, the weight of each country in decisions, and the possibility of imposing national priorities on the other members. Nigeria enters this debate as the bloc's largest economy and as the country with the greatest capacity to influence the success of the ECO.

Their participation is indispensable, but their weight generates concerns among smaller states. A union dominated by Abuja could replace monetary fragmentation with a regional dependence organized around a single economic and political center.

Countries linked to the CFA franc join the project with common institutions, shared monetary rules, and an integration experience that other members lack. However, this advantage also fuels controversies regarding the colonial legacy, the relationship with the euro, and the effective autonomy of the future currency.

The ECO will have to reconcile trajectories born from different monetary histories and political interests. By retaining the franc, Guinea-Bissau prevents the dispute from being resolved solely by the largest blocs. The country demonstrates that states with national currencies can demand their own guarantees before accepting common authority.

The decision increases Guinea-Bissau's negotiating leverage, but could encourage other governments to seek exceptions, additional preparation periods, or differentiated accession models. ECOWAS faces a difficult political choice.

It can move forward in July 2027 with an initial group of prepared countries and accept integration at different speeds, or wait for broader convergence. The first option will create central and peripheral members. The second will prolong a project that has been repeatedly postponed. In both paths, the struggle for power will accompany monetary construction.

Guinea-Bissau's position does not end the ECO project, but it forces ECOWAS to confront questions that the political calendar cannot resolve. The single currency can only function when states accept common rules, credible institutions, and a distribution of power that does not transform smaller countries into participants without influence.

Guinea-Bissau retains the Guinean franc and national instruments of economic policy, but remains within the regional discussion. This strategy allows for observation of negotiations, evaluation of criteria, and demand for guarantees before making irreversible commitments. The choice protects national autonomy, although it reduces the clarity of the collective project.

For citizens, the decisive issue is not the name printed on the banknotes, but purchasing power, prices, access to credit, wages, and trust in institutions. Without concrete results, the ECO will remain divided between the promise of African autonomy and the fear of an authority detached from national needs.
