China's policy-imposed capacity ceiling of 45 million tonnes per year remains the single most important structural factor in the global aluminum market. With utilization rates at 97%, China's production is effectively maxed out at 43.6 million tonnes annualized through May 2026. The National Development and Reform Commission (NDRC) has shown no indication of raising the cap, prioritizing carbon reduction targets over industrial output.
The cap creates a peculiar dynamic for the global market. Chinese demand growth — driven by solar PV frames, EV production, and grid infrastructure — is increasingly being met by imports rather than domestic production growth. China's net imports of primary aluminum reached 1.2 million tonnes in January-May 2026, up 38% year-on-year, with Russian metal accounting for 45% of the inflow.
Outside China, supply growth is equally constrained. European smelters continue to operate at just 72% of capacity, with energy costs in Germany and France remaining 60% above pre-2022 levels despite declining gas prices. The restart of idled European capacity has been minimal, with only 200,000 tonnes of the 1.1 million tonnes curtailed since 2022 coming back online.
New smelting capacity in the Middle East and India is ramping slowly. Alba's Line 6 expansion in Bahrain is operating at 80% of its 540,000-tonne capacity. India's National Aluminum Company (NALCO) announced a 400,000-tonne greenfield smelter in Odisha, but the project is not expected to begin production before 2028.
The supply ceiling is structural — it will not be lifted, and no meaningful ex-China capacity is coming online before 2028. Buyers should normalize higher aluminum prices as the new baseline. Secure multi-year contracts with price escalation clauses tied to the LME cash price rather than fixed pricing. The current $3,700-3,800/mt range likely represents a floor rather than a ceiling for the medium term.
