Gabon’s escalating public debt: a critical financial outlook for 2027

Gabon’s public debt is on a concerning upward trajectory, with projections indicating it will reach 94.3% of the nation’s Gross Domestic Product (GDP) by 2027. This financial path, which began during the transitional presidency and has been reaffirmed under the leadership of Brice Clotaire Oligui Nguema, places the Central African nation at a critical threshold. It significantly surpasses the 70% GDP convergence criteria established by the Economic and Monetary Community of Central Africa (CEMAC).

A debt path raising concerns among financial partners

The accelerated growth of Gabon’s debt portfolio stands in stark contrast to the fiscal discipline commitments made to multilateral lenders. Despite substantial oil revenues and a surge in manganese prices—Gabon being a leading global producer—the country’s public finances struggle to generate the necessary margins for debt reduction. A growing portion of state revenue is now consumed by debt servicing, thereby diminishing the capacity for crucial investments in infrastructure and social services.

This dynamic unfolds as the International Monetary Fund (IMF) suspended its disbursements under the extended credit facility in 2024, citing concerns over financial governance lapses and spending overruns. 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 incur higher costs compared to concessional windows.

The risky gamble of public spending-led recovery

Since assuming power in August 2023 following the overthrow of Ali Bongo Ondimba, General Oligui Nguema has leveraged public procurement as a tool for political legitimation. There has been a proliferation of road infrastructure projects, rehabilitation of social facilities, and housing programs, all presented with a proactive display aimed at signaling a clear break from previous administrations. However, this budgetary impetus has resulted in a widening primary deficit and an accumulation of domestic arrears owed to state suppliers.

Specifically, Gabon’s public debt stock is anticipated to climb from approximately 73% of GDP in 2024 to 94.3% by 2027, according to official budget documents. Such a rapid increase over three fiscal years indicates a growing dependence of the national budget on borrowing rather than on internal tax mobilization. Gabon’s tax pressure rate, historically low for a middle-income country, remains a persistent point of contention with technical partners.

Budgetary sovereignty and investor signaling

For a sovereign issuer like Gabon, actively participating in international markets through several eurobonds, the evolution of its credit rating is a direct concern. Rating agencies have already revised the country’s outlook multiple times, penalizing the uncertainty surrounding its fiscal trajectory and its capacity to refinance upcoming maturities. A sustained breach of the 90% of GDP threshold exposes Libreville to higher costs for its external debt and a shrinking pool of investors willing to subscribe to its bond issuances.

Within the sub-region, Gabon’s situation is closely monitored by CEMAC partners, who fear 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 exhibit strained debt profiles.

The credibility of this announced trajectory remains a key question. 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 reinstatement of financial cooperation programs. However, the Gabonese executive must complement its infrastructure ambitions with a credible fiscal consolidation plan. This is a crucial prerequisite to prevent public debt from becoming a structural vulnerability for the country’s economy in the medium term. The 94.3% of GDP threshold by 2027 is explicitly outlined in the official projections.
