LME aluminum settled at $3,164/mt on June 28, a modest 1.02% daily gain that masks a bruising 12% correction from the June 6 peak of $3,597. The correction has been broad-based: COMEX aluminum dropped 9.3% in a single session to $3,310/mt, while SHFE aluminum held relatively steady at ¥24,560/mt. Year-on-year, LME aluminum prices remain approximately 44% above their June 2025 levels of around $2,200/mt, which is the stat that matters most. This is not a market that has broken — it is a market that ran too far, too fast, on supply disruption fears, and is now consolidating as those fears are reassessed.
The inventory story is genuinely remarkable. LME registered aluminum stocks have fallen to levels last seen in the early 2000s, driven by a structural drawdown that has persisted for over 18 months. But the composition of those stocks is equally important: approximately 60% of LME aluminum inventory is of Russian origin, held under sanctions frameworks that restrict but do not prohibit trading. The US and UK ban on new Russian metal entering LME warehouses (effective April 2024) created a bifurcated market where Russian metal trades at a persistent discount to non-Russian brands. The EU's February 2026 geographic restrictions added another layer of compliance friction. The net effect is that 'available' inventory — metal that can be freely traded without sanctions complications — is far smaller than the headline number suggests.
Goldman Sachs Research's global aluminum supply-demand model projects a 720,000-tonne deficit in 2026, driven by constrained Chinese production growth and resilient demand from electrification and construction. China's aluminum smelters are running near the government-mandated capacity ceiling of approximately 45 million tonnes per year, with the State Council showing no appetite to raise that limit. Meanwhile, Yunnan province — which hosts roughly 12% of China's smelting capacity — faces recurring hydropower curtailments during dry seasons. BMI (Fitch Solutions) expects global aluminum production growth to slow to 1.6% in 2026, insufficient to close the gap with demand growth projected at 2.4%.
Guinea's bauxite dominance has become the aluminum market's single most important geopolitical variable. The West African nation now supplies 74% of China's bauxite imports and controls approximately 40% of global seaborne bauxite exports. In 2025, Guinea exported 183 million tonnes of bauxite, a 25% year-on-year surge that flooded the market and contributed to a 50% collapse in bauxite prices through early 2026. But the supply flood has a dark side: Guinea's military government has shown an increasing willingness to revoke mining concessions and seize assets. Emirates Global Aluminium's GAC subsidiary lost its 690 km² concession in July 2025 after months of dispute over customs duties and unfulfilled refinery commitments. SD Mining and Guinea Investment Corporation have also faced operational suspensions. The government's explicit policy is to force bauxite miners to build domestic alumina refineries, and companies that resist face expropriation. China's deepening dependence on Guinean bauxite — imports grew from 334,000 tonnes in 2015 to 149 million tonnes in 2025 — creates a vulnerability that the aluminum market has not adequately priced.
Alumina costs provide a cost floor. LME alumina (Platts) closed at $307.21/mt on April 28, and prices above $300/mt represent a meaningful cost input for smelters. Alumina accounts for roughly 35-40% of primary aluminum production costs. At current alumina prices and LME aluminum at $3,164/mt, the median smelter is profitable, but the margin is thinner than it appears once power costs — which vary dramatically by region — are factored in. European smelters, facing power costs 3-4 times higher than Chinese or Middle Eastern competitors, are operating at or near breakeven. Chinese smelters in coal-dependent provinces face carbon cost escalation under the expanding emissions trading scheme. The cost curve support around $2,800-$3,000/mt is real, which limits how far this correction can run before capacity curtailments begin.
Demand-side dynamics are bifurcated by region. Chinese aluminum demand grew approximately 4% in the first half of 2026, driven by EV production (aluminum content per vehicle continues to rise as automakers pursue lightweighting), solar panel frames, and transmission infrastructure. US demand is being supported by reshoring of manufacturing — aluminum extrusion and rolling mill capacity expansions announced in 2024-2025 are now coming online, creating incremental primary metal demand. European demand remains the weakest link, with construction activity depressed by elevated interest rates and automotive production recovering only slowly from the 2024 trough. The net result is global demand growth of approximately 2.4% for 2026, outpacing supply growth of roughly 1.5%.
Analyst projections for the remainder of 2026 cluster around $3,000-$3,400/mt. Goldman Sachs sees $3,100-$3,300 as the near-term equilibrium, with upside if Chinese production curtailments deepen. BMI Research forecasts an average of $3,050/mt for H2 2026. The bull case — a Guinean supply disruption during the Q3 rainy season, when exports seasonally decline — could push prices to $3,600-$3,800. The bear case — a sharper-than-expected slowdown in Chinese construction — would test the $2,800 cost support.
The week ahead brings several catalysts. LME inventory data on Monday will confirm whether the recent correction has triggered any restocking. China's official manufacturing PMI, due July 1, will signal whether the factory sector's tentative stabilization is holding. And any news out of Conakry on Guinea's mining license review process — which now covers multiple major bauxite operations — could trigger sharp price moves in both alumina and aluminum. The macro overlay remains cautious: WTI crude fell 3.7% in Friday's session to $69.23/bbl, and broader commodity weakness suggests fund positioning in aluminum may still be long and vulnerable to liquidation.
Aluminum buyers should treat this 12% correction as an opportunity, not a signal that the bull market is over. The structural deficit — 720,000 tonnes per Goldman Sachs, with constrained Chinese output and resilient demand — has not changed. What has changed is the price, which is now $400/mt cheaper than it was three weeks ago. Three specific actions: First, lock Q3 fixed-price contracts now. If your procurement cycle allows, secure volumes at current levels before any Guinea-related supply shock or Chinese curtailment announcement reverses the correction. Second, reassess your alumina exposure. If you buy primary aluminum but do not track alumina costs, you are missing the leading indicator. Alumina above $300/mt signals smelter cost stress; above $350/mt, curtailments become likely. A rising alumina price historically leads aluminum by 4-6 weeks. Third, map your supply chain's exposure to Russian-origin metal. The sanctions compliance burden is escalating, and the discount on Russian metal creates a temptation that comes with legal risk. If your contracts do not specify origin, they should. The EU's February 2026 restrictions make this a compliance priority, not just a pricing consideration.
