Overseas Market: As of May 6, 2025, the FOB Western Australia alumina price was $348/mt, with an ocean freight rate of $20.50/mt. The USD/CNY exchange rate selling price was around 7.23. This price translates to an external selling price of approximately 3,091 yuan/mt at major domestic ports, which is 195 yuan/mt higher than the domestic alumina price. The alumina import window remained closed.
Summary: With the commissioning of new capacity and the resumption of production from maintenance-related production cuts, the operating capacity of alumina has rebounded significantly. In the final week before the holiday, the weekly operating capacity increased by 3.48 million mt/year on a WoW basis. In the short term, some alumina refineries have plans for maintenance-related production cuts, but at the same time, new alumina capacity will further ramp up production, and the operating capacity of alumina may exhibit minor fluctuations. On the cost side, caustic soda prices have remained largely stable overall, while bauxite prices have decreased somewhat, leading to a pullback in alumina costs and alleviating the loss pressure on alumina refineries. In the futures market, with the downward shift in the cost line and a slight recovery in supply, the futures market has been in the doldrums recently, with some transactions occurring for warrant cargoes. The total registered volume of warrants decreased by 11,500 mt in a single day. Overall, the tightening of spot alumina supply caused by the concentration of maintenance-related production cuts in the earlier period is expected to ease, and short-term prices are expected to fluctuate.
