Guinea’s mining boom is no longer prospective. Bauxite production increased by an estimated 30 percent in 2025, while Simandou iron ore exports began in November. Yet the World Bank estimates that the current-account deficit remained wide at 14.5 percent of GDP in 2025, largely because mining investment generated substantial imports of equipment and infrastructure.
This does not mean mining exports are underperforming. It means gross export receipts and the foreign exchange ultimately retained within Guinea are two different measures.
A trade surplus that does not become a current-account surplus
The latest published balance-of-payments figures make the distinction clear. During the third quarter of 2025, Guinea recorded a goods trade surplus of $965.4 million. Mining products represented almost 92 percent of total exports.
Despite that surplus, the current account remained in deficit by $106.5 million. The reason lies outside the merchandise trade balance. The services account recorded a deficit of $783.6 million, while the primary-income account posted a deficit of $430.3 million.
The services deficit was driven partly by management consulting, technical assistance and other specialized services purchased abroad by mining companies. Transport costs also increased, reflecting Guinea’s continued reliance on foreign freight and logistics providers. Dividend payments and withdrawals from foreign-owned companies reached approximately $395.4 million during the quarter.
The balance-of-payments problem is therefore not simply how much Guinea exports. It is also how much the sector spends abroad to operate, expand and remunerate foreign investors.
The mining boom also creates imports
Imports rose by more than 57 percent year on year during the third quarter of 2025. Equipment, petroleum products and electrical materials accounted for a substantial part of the increase.
This reflects the capital-intensive nature of the current mining cycle. Guinea is importing machinery, energy and technical capacity to build projects expected to generate future exports. Part of the current-account deficit is therefore linked to an investment phase rather than a collapse in external competitiveness.
The World Bank expects this pressure to ease rapidly. It projects the current-account deficit to fall to 2.6 percent of GDP in 2026, before moving into surplus in 2027 as investment-related imports decline and Simandou exports expand.
Export earnings remain a structural issue
The projected improvement does not resolve the question of foreign-exchange retention.
In March 2026, the Governor of the central bank reported that mining companies exported goods worth approximately $11.13 billion during 2025. Under the requirement to repatriate at least half of export earnings, $5.57 billion should have returned through the Guinean financial system. Actual repatriation reached $3.69 billion, equivalent to 66 percent of the amount required, not 66 percent of total export receipts.
This gap matters because mineral exports can increase without producing an equivalent rise in domestic liquidity, reserves or financing capacity.
The Simandou test
At full capacity, Simandou is expected to export up to 120 million tonnes of iron ore annually. Its effect on Guinea’s external position will depend not only on production volumes, but also on domestic procurement, service localization, tax enforcement, dividend flows and compliance with foreign-exchange repatriation rules.
The June 2026 decision to end raw gold exports and direct production toward local refining signals a broader policy effort to retain more value domestically. However, the wider transformation will depend on whether similar progress occurs across mining services, logistics, processing and domestic supply chains.
Guinea’s current account is expected to improve as Simandou scales up. The deeper test is whether this improvement produces lasting reserves and domestic industrial capacity, rather than a larger cycle of exports accompanied by equally large external payments.
