Guinea, the world's largest bauxite producer, is preparing to announce significant reforms next month aimed at regulating exports of the ore used to make aluminum, in a move expected to further boost prices for the industrial metal. The benchmark LME aluminum price has recently climbed above $3,600 per ton, with the cash settlement price reaching $3,768 per ton on May 14. Since the second half of 2025, the three-month LME aluminum futures price has surged nearly 50%, prompting Citigroup to declare aluminum is experiencing its "strongest bullish setup in over 50 years."
Guinea's planned export controls are part of a broader "resource sovereignty" trend across Africa, where nations are increasingly managing exports of key minerals to secure greater pricing power and local value addition. This follows similar restrictions on cobalt and lithium by the Democratic Republic of Congo and Zimbabwe, respectively.
Accounting for over one-third of global bauxite output, Guinea's shipments surged by a quarter to 183 million tons in 2025, with growth accelerating further in the first three months of this year. Bouna Sylla, Guinea's Minister of Mines and Geology, stated this oversupply has driven market prices down by nearly half from their peak early last year. "Supply must not exceed demand," Sylla said in an interview. "We want to regulate the volume to bring prices back to a reasonable level."
Bauxite is the raw material for alumina, which is then processed into aluminum. Most of Guinea's bauxite production is shipped to China. The government is expected to finalize the new policy, first proposed several months ago, in June. Sylla added that mining investors are "very interested in seeing prices rise."
Following precedents set by other African nations, Guinea is also seeking to attract investment in local processing facilities to extract more value from its natural resources. The country is pushing miners to build refineries capable of producing alumina, with three facilities currently planned or under construction to supplement its sole existing major plant. The government aims for a total of five new refineries with a combined annual alumina capacity of approximately 7.2 million tons. However, this would still process less than 15% of the bauxite Guinea mined last year. Guinea also intends to seek a major investor for an aluminum smelter. "For us, moving from alumina to aluminum is inevitable," Sylla stated.
The long-term bull case for aluminum appears to be evolving from a "single smelter supply shock" to a comprehensive "supply reassessment" across the entire chain from bauxite to alumina to primary aluminum. Citigroup analysts believe aluminum is in one of its strongest bullish setups in over 50 years, potentially reaching $4,000 per ton in the next three months and $5,350 in a 2027 bull scenario. The core foundation is not a sudden demand explosion but a systematic weakening of supply elasticity, attributed to geopolitical conflicts damaging Middle Eastern smelting capacity, China's primary aluminum capacity ceiling, limited available idle capacity overseas, and inventories at multi-year lows.
Guinea's export controls add a new catalyst to this narrative. As the top global producer, its move to restrict bauxite exports would alter the "cost base" and supply expectations for the entire aluminum chain. Since most of Guinea's bauxite goes to Asia, the global hub for aluminum consumption and processing, this policy carries significant global pricing implications.
The bullish stance from Citigroup and JPMorgan hinges on aluminum markets facing a combination of low inventories, low supply elasticity, and high policy-driven demand. In traditional cycles, high prices stimulate supply and curb demand, leading to self-correction. However, current constraints include capped Chinese capacity, slow recovery of lost Middle Eastern capacity, and impacts from sanctions, tariffs, and supply chain realignments in the West, all while demand from green grids, renewables, electric vehicles, and AI data center power infrastructure remains robust and policy-supported.
Separately, a team led by Michael Hartnett, Bank of America's chief investment strategist, recently stated that investors will continue flocking to commodities for years to come, with a bull market potentially lasting until the end of 2030. They view commodities as a premier "post-war trade" theme, poised to outperform stocks as investors seek hedges against risk, inflation, and a weaker dollar. Geopolitics and the global AI race are intensifying competition for energy, rare earths, minerals, and key commodities. Hartnett summarized the core logic: whoever controls chips, rare earths, minerals, and efficient energy wins the global AI war.
This implies that, in Bank of America's view, the pricing core of the post-war world is shifting beyond just interest rates and corporate earnings to encompass commodity supply security, supply chain control, and fiscal expansion. With resource-exporting nations like Indonesia also considering new agencies to tighten commodity exports, and prices for industrial metals like copper, aluminum, and nickel rising this year—driven by surging demand for metals and minerals critical for building AI data centers—commodities are becoming a central "AI investment theme." This theme extends beyond AI chips and servers to encompass the underlying energy, industrial metals, chemicals, and resource security premiums required to support the expansion of AI computing infrastructure.
