Commodities trader Gunvor is once again under criminal investigation in Switzerland, this time concerning a substantial oil contract valued at approximately one billion dollars with Gabon. The Federal Public Prosecutor’s Office (MPC) is spearheading the proceedings, meticulously scrutinizing the terms of attribution and the intricate financial framework that underpinned the agreement for lifting Gabonese crude oil. Geneva remains a pivotal global hub for hydrocarbon trading, and in recent years, several of its prominent players have faced legal challenges related to corruption in Africa.

Renewed focus on Gabon’s crude oil sales

The contract currently under the microscope of Swiss investigators involves shipments of Gabonese petroleum amounting to nearly one billion dollars, according to publicly disclosed information. Swiss magistrates are actively working to ascertain whether intermediaries received commissions intended to improperly influence the Gabonese authorities’ decision in awarding the lucrative market. Gabon, Africa’s twelfth-largest crude oil producer, with an output of roughly 200,000 barrels per day, remains heavily reliant on these oil sales for its national budget revenues.

The transaction being examined dates back to a period when Libreville sought to diversify its buyers and swiftly monetize its oil production. So-called pre-financing contracts, where a trader advances funds in exchange for future deliveries, have become a common practice in African oil-producing economies grappling with fluctuating oil prices. These arrangements, inherently opaque in their structure, are increasingly attracting the attention of European and North American regulatory bodies.

Gunvor: a recurring subject of swiss judicial scrutiny

For the Geneva-based conglomerate, this new case emerges while it is still addressing its historical issues in Africa. In 2019, the MPC had already imposed a penalty of nearly 94 million Swiss francs on Gunvor for organizational shortcomings in corruption cases involving Congo-Brazzaville and Côte d’Ivoire. Following that judgment, the company committed to enhancing its internal compliance procedures, driven by pressure from its banking partners and institutional stakeholders.

The repeated nature of these legal proceedings raises significant questions about the true efficacy of the control mechanisms implemented since the previous conviction. Swiss authorities, who were long criticized for their perceived leniency towards major trading firms, have notably tightened their judicial doctrine. The establishment in 2020 of corporate criminal liability for the failure to prevent corruption has broadened the MPC’s investigative and prosecutorial powers. Consequently, the trading sector, which contributes approximately 4% to Switzerland’s GDP, has become a priority area for this more stringent enforcement policy.

Libreville navigates fresh international pressures

For Gabonese authorities, this investigation comes at a particularly sensitive juncture. The new leadership, installed following the 2023 transition, has championed the traceability of oil revenues as a cornerstone of its legitimacy. Both the Société Gabonaise de Raffinage and the national company Gabon Oil Company are now tasked with clarifying the commercialization channels inherited from the preceding decade. Formal cooperation with Swiss justice, should it be initiated, would provide Libreville with a crucial opportunity to publicly demonstrate a clear break from past practices.

However, the implications of this case extend beyond a mere bilateral scope. The Extractive Industries Transparency Initiative (EITI), which Gabon has recently rejoined, actively monitors the publication of oil lifting contracts. Multilateral lenders, including the International Monetary Fund, often condition their support on improved governance within the hydrocarbon sector. Documented allegations or findings involving Gabonese intermediaries could significantly impact ongoing discussions surrounding a potential new financial program for the nation.

Within the Swiss trading community, the repercussions could be widespread. Several of Gunvor’s competitors, already under investigation for similar allegations in countries like Angola, Nigeria, and the Republic of Congo, will be closely observing the legal classifications determined by the magistrates. The prospect of confiscating illicit profits, which in comparable cases have reportedly amounted to tens of millions of dollars, remains a powerful deterrent. The Swiss investigation is now formally underway and is expected to see further developments in the coming months.
