This price translates to approximately 3,275 yuan/mt at major domestic ports, which is 198 yuan/mt higher than the domestic alumina price. The alumina import window remained closed.
Summary: Last week, maintenance and production cuts were concentrated among alumina enterprises in south China, leading to a 2.9 million mt/year decrease in operating capacity on a QoQ basis, further tightening spot supply. Additionally, alumina enterprises have been facing continuous losses in recent months, with a strong intention to refuse to budge on prices. Coupled with maintenance and production cuts, the tightening of spot supply has led to a continuous rebound in spot transaction prices. Last Friday, due to the revocation of mining rights for some enterprises in Guinea, some currently operating enterprises received notices of suspension. This week, some miners declared force majeure to shipping companies. On Tuesday evening, in the order read by the Guinean authorities, the revoked mining rights were placed in strategic reserve areas. The specific impact of this incident on Guinea's bauxite supply remains to be assessed. In the short term, it may provide sentiment-based support for bauxite prices, thereby offering cost support for alumina. Subsequent attention should be paid to changes in the operating capacity of alumina refineries, as well as the shipment volume of Guinea's bauxite from the raw material side and the dynamics of related enterprises.
