Guinea is on track to post one of Africa’s strongest economic growth rates for 2026-2027, driven largely by the ramp-up of the Simandou iron ore project. According to the International Monetary Fund, the country’s GDP is expected to grow by 8.7 percent this year, putting Conakry ahead of every other economy in West Africa, well beyond Benin, Niger or Côte d’Ivoire, and nearly double the average across the WAEMU bloc. The Fund even projects an acceleration to 9.3 percent in 2027, which would make Guinea the fastest-growing economy in all of Sub-Saharan Africa. The World Bank is even more bullish, forecasting an average of 10.3 percent growth over the 2026-2028 period.
Regarded as the largest untapped high-grade iron ore deposit in the world, Simandou began production in December 2025, with an eventual target of 120 million tonnes a year. Exports are expected to reach between 15 and 20 million tonnes in 2026, before jumping to 40 or 50 million the following year as infrastructure comes fully online. The project has drawn close to $8.6 billion in investment, split between the mine itself and a vast logistics network linking the country’s southeast to Atlantic ports along more than 600 kilometers of new railway. Two consortiums are running the operation, one led by China’s Baowu Resources, the other a partnership between Rio Tinto and Chinalco, with the Guinean state holding a 15 percent stake.
The mining sector as a whole is projected to grow 8.8 percent in 2026 and 11.6 percent in 2027, a pace that stands in sharp contrast to the rest of the economy, where non-mining growth hovers around just 5.6 percent on average over the same period. Bauxite, another pillar of Guinean exports, is also booming: the country shipped roughly 183 million tonnes of it in 2025, a 25 percent jump from the year before. Yet this mining boom raises a deeper question for authorities in Conakry, namely how to turn a windfall concentrated in a handful of industries into prosperity shared more broadly across the rest of the economy.
