Industry News:
(1) Would a blockade of the Strait of Hormuz affect bauxite and alumina? According to SMM analysis, the impact on China is expected to be limited. China imports little bauxite via the Strait of Hormuz. China exports a small amount of alumina to the Middle East, but the volume is relatively small, totaling around 150,000 mt from January to May 2025, accounting for 13% of total exports. If the Strait of Hormuz is blocked, it is expected to affect alumina and bauxite imports to the Middle East. The blockade may cause crude oil prices to rise, driving up ocean freight rates for bauxite and alumina. However, the impact on long-term contracted shipping prices for Guinea bauxite is expected to be limited, while spot shipping freight rates may be affected, with limited upside for bauxite prices. Some market participants assess that the probability of a blockade of the Strait of Hormuz is low, and it is expected to have little substantive impact on the market. According to SMM, starting from June 20, a large alumina refinery in Shandong adjusted the purchase price of 32% ionic membrane liquid caustic soda, reducing it by 20 yuan/mt from the base price of 800 yuan/mt. The ex-factory price under the two-invoice system was implemented at 780 yuan/mt (approximately 2,438 yuan/mt converted to 100% concentration).

Overseas Market: As of June 23, 2025, the FOB Western Australia alumina price was $370/mt, with an ocean freight rate of $22.6/mt. The USD/CNY selling rate hovered around 7.2. This price translates to approximately 3,276 yuan/mt for the external selling price at major domestic ports, which is 111.18 yuan/mt higher than the domestic alumina price. The alumina import window remained closed.
Summary:
Last week, some alumina refineries completed maintenance and resumed production. Meanwhile, considering ore costs, there were reports of new production cuts. The operating capacity of alumina refineries experienced both increases and decreases. Overall, the operating capacity of alumina refineries decreased by 440,000 mt/year MoM to 88.57 million mt/year last week. Spot alumina supply remained loose. Last week, the total inventory of alumina at aluminum smelters increased by 8,600 mt to 2.655 million mt. In the short term, the alumina market fundamentals are expected to remain relatively loose, and spot alumina prices are expected to drop back slightly. Yesterday, the futures market fluctuated upward in the morning session due to news of the blockade of the Strait of Hormuz. However, after assessing that it would not temporarily affect the supply of imported ore to China, the futures market pulled back. Going forward, it is necessary to continuously monitor changes in the operating capacity and profitability of domestic alumina enterprises.
