Gabon’s public debt continues its upward trajectory, with projections indicating it will reach a significant 94.3% of its gross domestic product (GDP) by 2027. This anticipated increase, which began during the transitional presidency and has been solidified under Brice Clotaire Oligui Nguema’s leadership, places the nation precariously close to — and indeed, beyond — the 70% GDP threshold set by the Economic and Monetary Community of Central Africa (CEMAC) as a convergence criterion.
A debt path raising concerns among financial partners
The rapid expansion of Gabon’s debt stock stands in stark contrast to its commitments regarding fiscal discipline made to multilateral lenders. Despite substantial oil revenues and a resurgence in manganese prices, a commodity where Gabon ranks among the world’s top producers, the country’s public finances are struggling to generate the necessary surpluses for debt reduction. A growing portion of state revenues is now consumed by debt servicing, thereby diminishing the funds available for crucial investments in infrastructure and social services.
This dynamic unfolds as the International Monetary Fund (IMF) halted its disbursements under the Extended Credit Facility in 2024, citing lapses in financial governance and an escalation of public expenditures. Without an active program with the Bretton Woods institution, Libreville finds itself increasingly reliant on the regional public securities market and bilateral financing, both of which typically carry higher costs compared to concessional lending windows.
The high-stakes gamble of public spending-led recovery
Since assuming power in August 2023 following the ousting of Ali Bongo Ondimba, General Oligui Nguema has strategically leveraged public procurement as a tool for political legitimation. A surge in road infrastructure projects, the rehabilitation of social facilities, and housing programs have been initiated, signaling a determined effort to differentiate the new administration from previous management. However, this aggressive fiscal stimulus has simultaneously led to a widening primary deficit and a build-up of domestic arrears owed to state suppliers.
Specifically, official budget documents suggest that Gabon’s public debt stock is set to climb from approximately 73% of GDP in 2024 to 94.3% by 2027. Such a rapid increase over just three fiscal years highlights a growing reliance of the national budget on borrowing rather than on robust internal tax mobilization. Gabon’s tax pressure rate, historically low for a middle-income country, remains a persistent point of contention with technical partners.
Fiscal sovereignty and the investor signal
For a sovereign issuer like Gabon, which participates in international markets through several Eurobonds, the trajectory of its credit rating is a direct and critical concern. Rating agencies have repeatedly adjusted the country’s outlook, reflecting uncertainties surrounding its fiscal path and its ability to refinance upcoming maturities. A sustained breach of the 90% of GDP threshold would likely translate into higher costs for Gabon’s external debt and a shrinking pool of investors willing to subscribe to its bond issuances.
Within the sub-region, Gabon’s situation is closely observed by CEMAC partners, who are wary that an isolated fiscal slippage could destabilize the common foreign exchange reserves managed by the Bank of Central African States (BEAC). Regional monetary authorities have consistently reiterated the necessity of returning to sustainable debt ratios, particularly as Chad, Congo-Brazzaville, and Cameroon also contend with elevated debt profiles.
The question of the announced trajectory’s political credibility persists. The transition to a civilian constitutional framework, confirmed by the November 2024 referendum and the April 2025 presidential election, theoretically paves the way for the restoration of financial cooperation programs. Nevertheless, it remains imperative for the Gabonese executive to complement its ambitious infrastructure plans with a credible fiscal consolidation strategy. This is a fundamental prerequisite to prevent public debt from becoming a structural vulnerability for the nation’s economy in the medium term. Official projections explicitly confirm the 94.3% of GDP threshold for 2027.
