On March 31, 2026, the aluminum industry chain showed a highly dramatic diverging trend: the benchmark electrolysis aluminum futures contract was ignited by the fighting in the Middle East and surged strongly; while the alumina futures contract saw a widespread green fade and fell against the trend. This “strong aluminum, weak alumina” divergence is not market chaos, but an accurate reflection of a mismatch between geopolitical crises and the industrial supply-demand cycle.

Currently, the aluminum market is undergoing a logical shift from “driven by raw material costs” to “geopolitical supply panic.”

【Electrolytic Aluminum: Geopolitics Ignites a “Hard Supply Shortfall”】

The core logic behind the explosive surge in electrolytic aluminum prices is that the conflict in the Middle East has upgraded from “logistics disruptions” to “capacity destruction.”

1. Physical loss of capacity: The attacks on Abu Dhabi Global Aluminum (EGA) and Bahrain Aluminum (Alba) are no longer just simple shipping delays; they directly hit about 3.9% of the global electrolytic aluminum capacity. Once electrolytic aluminum cells are shut down due to power outages or physical damage, the restart cycle can last for months or even years. This “irreversible” supply loss forces the market to reprice the risk premium.

2. The “suffocation effect” of the Strait of Hormuz: Middle East aluminum plants highly rely on imported alumina raw material through the strait. A blockade of the strait not only prevents finished products from being shipped out, but also prevents raw materials from coming in. Bahrain Aluminum has been forced to cut production due to raw material shortages, and this “food cutoff” risk is spreading across the entire Gulf region.

3. Fragility of overseas inventories: LME aluminum inventories have fallen to multi-year lows below 400k metric tons, leaving the market with virtually no buffer. Any disturbance on the supply side will trigger a fierce short-squeeze-driven行情.

【Alumina: A Game Between Overcapacity Gravity and Cost Support】

By contrast, the decline in alumina prices returns to its own supply-demand fundamentals. Although the Middle East situation would theoretically push up energy costs, the alumina market is facing a more severe “gravity of overcapacity.”

1. Demand-side “downward drag”: Electrolytic aluminum is downstream of alumina. The shutdowns and production cuts at electrolytic aluminum plants in the Middle East directly reduce demand for alumina. Alumina that was originally used to supply Middle East aluminum plants has turned into “overcapacity,” further worsening the globally loose supply situation of alumina.

2. The “flood tide” on the supply side is coming: As the world’s largest alumina producer, China is set to see a concentrated rollout of new capacity in the second quarter (such as Hebei Wenfeng, Tiandong Jinxin, etc.). Although there is uncertainty regarding Guinea bauxite export policies, the domestic expectations of large-scale new capacity are sufficient to offset cost support from the raw material side.

3. Diminishing marginal support from costs: Although increases in caustic soda and energy prices raise alumina production costs, in the face of severe supply and demand oversupply, cost support looks weak and ineffective. The market is more willing to trade the reality of “overcapacity” rather than the expectation of “costs.”

【Outlook: Divergence will Continue—Watch for the Convergence of the “Scissors Gap”】

Overall, the diverging trends between electrolytic aluminum and alumina essentially reflect a game between “geopolitical risk” and “industrial cycle oversupply.”

Short-term trend: As long as the conflict in the Middle East does not ease, the logic of the supply shortfall for electrolytic aluminum will dominate the market, and aluminum prices will remain at high levels in a volatile range, or even rise further. Alumina, meanwhile, will continue to look for bottom support under persistent oversupply pressure.

Risk warning: Investors should be alert to the excessive expansion of the “scissors gap.” If electrolytic aluminum prices are too high and suppress downstream demand, or if alumina prices fall below the cost line and trigger large-scale production cuts, this diverging pattern will reverse.

In summary, today’s divergence in the aluminum market is the result of geopolitical storms and the规律 of the industrial cycle working together. Amid the squeeze between war and oversupply, the aluminum industry chain is undergoing a profound revaluation of value.
