Industry news:
Basis report: According to SMM data, as of March 31, the SMM alumina index was at a premium of 146 yuan/mt against the most-traded contract's latest transaction price at 11:30.
Warrant report: As of March 31, the total registered volume of alumina warrants increased by 601 mt to 299,100 mt compared to the previous trading day. The total registered volume of alumina warrants in Shandong remained flat at 4,513 mt, in Henan at 25,800 mt, in Guangxi at 49,800 mt, in Gansu at 22,500 mt, and in Xinjiang increased by 601 mt to 196,400 mt.
Overseas market: As of March 31, 2025, the FOB alumina price in Western Australia was $377/mt, with an ocean freight rate of $21.40/mt, and the USD/CNY exchange rate selling price was around 7.26. This price translates to a domestic mainstream port selling price of approximately 3,092 yuan/mt, which is 258 yuan/mt higher than the domestic alumina price, keeping the alumina import window closed. Based on the latest FOB transaction price of $368/mt in Eastern Australia, the domestic mainstream port selling price is around 3,300 yuan/mt, only less than 200 yuan/mt higher than the SMM alumina price index. If overseas alumina prices further decrease and the rate of decrease exceeds that of domestic prices, the alumina import window may gradually open. On the export side, based on the latest spot transaction price of alumina in Shandong, the domestic alumina export cost is around $450/mt, higher than the overseas spot alumina price, keeping the export window closed.
Summary: Last week, the weekly operating rate of alumina was lowered again, with the national total operating capacity of metallurgical alumina reduced to 87.3 million mt/year, and the weekly operating capacity decreased by 700,000 mt/year MoM. However, the overall supply surplus in the alumina market has not yet reversed. According to SMM data, as of last Thursday, the total operating capacity of domestic aluminum was 43.88 million mt/year, translating to an alumina demand operating capacity of around 84.47 million mt/year, with theoretical demand increasing slightly but still below actual operating levels. On the supply side, domestic bauxite supply remains low, with limited increments. The increase in imported bauxite supply has driven the total domestic bauxite supply, and the supply-demand fundamentals of bauxite may become more relaxed than before, with bauxite prices likely to remain under pressure in the short term. Meanwhile, downstream aluminum plants reported that alumina procurement is mainly based on long-term contracts, and some plants that have stockpiled for winter are planning to actively reduce inventory. According to SMM statistics, alumina raw material inventory at aluminum plants decreased by 44,000 mt WoW. In the short term, alumina circulating supply is expected to remain relatively loose, and alumina prices may continue to operate under pressure. Subsequent attention should be paid to changes in alumina operating capacity.
