Alumina | Regional Supply Disruptions and Bauxite Expectations Drive Spot Price Hikes of Over 100 Yuan in June

In June, despite the continuous release of new alumina capacity in Guangxi, spot prices in multiple regions rose. This upward trend was primarily driven by tightening spot supplies in the north, short-term regional supply disruptions, and expectations regarding the details of Guinea's bauxite export quotas. Looking ahead to July, anticipated cost increases are likely to continue exerting influence, potentially allowing further room for spot price gains, though the rate of increase may narrow.

Spot Alumina Prices Rose by Over 100 Yuan Per Ton in Multiple Regions
The domestic spot alumina market experienced a rally in June, with prices in several regions rising by more than 100 yuan per ton; mainstream spot prices in Shandong, Shanxi, and Henan climbed to the 2,780–2,840 yuan/ton range. Upward price momentum was supported by a confluence of factors: production cuts or reductions at some Shanxi alumina plants, significant inventory held in delivery warehouses (limiting available supply), regional supply tightness, expectations regarding Guinea's export quota details, and essential restocking by downstream aluminum smelters.

Short-Term Supply Disruptions and Expectations Regarding Guinea's Bauxite Sector Are Key Drivers
In June, Shanxi conducted special safety inspections of non-coal mines and red mud storage facilities, leading to the temporary suspension or reduction of approximately 2 million tons of operating alumina capacity. Coupled with the fact that futures delivery warehouses held substantial inventory, the supply of tradable spot alumina in the northern market tightened. Meanwhile, the delayed release of details regarding Guinea's bauxite export quotas fueled market rumors of reduced annual export volumes. Additionally, Guinea is currently in its rainy season—limiting bauxite shipments—and market concerns over reduced import arrivals in the third quarter caused expectations of rising bauxite costs to be priced into the alumina spot market ahead of time. These regional supply disruptions and expectations regarding the bauxite sector served as the primary drivers behind the rise in spot alumina prices. Data monitored by Fubao Information indicates that as of June 26, the installed capacity of alumina enterprises stood at 116.75 million tonnes, with an operating capacity of 86 million tonnes; the capacity utilization rate was 73.66%, down 2.01 percentage points from the end of May. Specifically, for the week of June 26, the operating capacity of alumina enterprises in Shanxi was 15.6 million tonnes, with a utilization rate of 59.32%—a drop of 11.83 percentage points from late May—reflecting a significant reduction in output by local enterprises. In Henan, the capacity utilization rate was 56.62%, down 7.31 percentage points from late May. While output declined among enterprises in these two major high-cost inland regions, changes in other areas remained relatively minor.

Downstream Aluminum Smelter Demand Amplifies Price Volatility
Domestically, 95% of alumina products are used for electrolytic aluminum production. Current estimates place domestic installed aluminum smelting capacity at 45.53 million tonnes and operating capacity at approximately 44.364 million tonnes, resulting in a utilization rate of 97.44%—a relatively high level of activity. Regarding new capacity, a 1.4-million-tonne electrolytic aluminum project in Xinjiang has successfully powered up and is expected to reach full production by mid-July; a 350,000-tonne capacity project in Inner Mongolia is continuing to ramp up, with full production anticipated by the end of June; and a 300,000-tonne capacity project in the Northeast is already operating at full capacity. Electrolytic aluminum smelters in major production hubs like Shandong, Inner Mongolia, and Xinjiang are largely operating at full capacity, maintaining stable demand for raw material alumina. Concentrated, moderate restocking by some smelters prior to the Dragon Boat Festival also supported a rise in spot prices. Increased inquiries for spot cargoes—beyond long-term contract commitments—and heightened purchasing enthusiasm among traders further tightened short-term market liquidity; this supply-demand mismatch drove up spot transaction prices.

New Capacity Rollout Limits Scope for Spot Price Increases
While domestic alumina spot prices have risen, the continuous rollout of new capacity in Guangxi has acted as a constraint. Despite localized supply tightness, the overall market remains characterized by loose supply, which has significantly dampened the extent of spot price increases during the month. According to Fubao Information's data monitoring, 7.4 million tonnes of new alumina capacity are scheduled to come online in the Guangxi region this year. As of June 26, 5.4 million tonnes of this new capacity had already been commissioned; three enterprises began releasing products to the market in early May, and one additional enterprise is set to bring 2 million tonnes of new capacity online later this year.

Market Outlook: Spot prices in July are expected to rise further, though the rate of increase may narrow.
Regarding the market trend for July, alumina spot prices are expected to trend upward with a firm tone, shifting the price center higher, although the magnitude of the increase may contract; the national monthly average price is projected to hover around 2,750 yuan/tonne, within a range of 2,650–2,850 yuan/tonne. Bullish factors include: safety inspections in Shanxi are unlikely to be fully lifted in the short term, and combined with insufficient domestic ore supplies, some enterprises may maintain low operating capacities; the rainy season in Guinea is reducing bauxite shipments, and market expectations remain high pending the finalization of export quota details, while anticipated increases in ore costs continue to provide a floor for alumina spot prices; and electrolytic aluminum enterprises are expected to maintain high operating rates in July, ensuring stable "just-in-time" procurement that supports spot prices. Bearish factors include: electrolytic aluminum plants will likely prioritize long-term contract procurement in July, potentially weakening interest in spot market purchases outside of these contracts and leading to quieter spot trading; new capacity in Guangxi continues to ramp up, with new lines expected to reach full production by mid-July—increasing output and easing supply constraints—while high inventory levels also limit the scope for price increases; and the easing of tensions in the Middle East has lowered shipping costs, creating room for a decline in Guinean ore transaction prices and potentially weakening cost-side support. Overall, while alumina spot prices are expected to rise further in July, the pace of the increase may slow. The medium-to-long-term situation of domestic alumina spot oversupply remains unchanged; attention should be paid to the timing of policy implementation regarding Guinean ore and the maintenance schedules of domestic alumina enterprises.
