Alumina steady-to-soft as spot tightens, deepening losses fail to spur cuts

Domestic spot alumina prices edged down slightly last week amid flat trading activity. Recent alumina price movements were mainly attributed to earlier concentrated restocking by downstream buyers, which has led to accumulating inventories at rail stations and smelters. Coupled with supply-side maintenance-driven output cuts that are still building, readily available spot volumes have tightened relatively. Only sporadic tender deals were heard recently, leaving prices in a temporary steady phase. On the bauxite front, domestic ore prices saw limited movement last week. Supply-side bottlenecks are unlikely to ease in the near term, with mines prioritising captive supply, leaving little excess spot material available. For imported ore, freight rates rebounded slightly and consecutively last...

AL Circle Analysis: Guinea’s 150Mt bauxite cap, China’s import swings, US tariffs draw aluminium Q4’26

The global aluminium supply chain is facing a series of changes that extend from bauxite mines and alumina refineries to smelters, regional premiums and finished-metal trade. In 2026, the market’s direction is being shaped not only by production volumes but also by freight costs, export restrictions, shifting Chinese demand and tariffs. Developments across Guinea, Australia, China, Europe and North America point to a market where access to supply is increasingly as important as the availability of raw materials. Bauxite supply: Guinea’s cap meets a well-stocked China, but is it stable? Guinea remains central to the seaborne bauxite market, with its shipment connections to China demonstrating the importance of reliable logistics. A new sea-rail route has enabled a Guinea bauxite shipment...

Upstream weekly recap: Unprecedented alumina price growth is transforming market dynamics; China bauxite imports reach a new high

Currently, if anything is grabbing the maximum attention in the upstream aluminium sector, it is the unprecedented price surge in China's alumina prices. Both domestic and imported prices have skyrocketed over the week, transforming the market dynamics and raising concerns among primary aluminium producers about escalating production costs. According to the Shanghai Metals Market survey, China's domestic average alumina price has skyrocketed by RMB 1,035 per tonne on a year-on-year comparison, reaching RMB 3,968 per tonne as of September 13. The significant growth phenomenon primarily started in late August on account of excessive demand due to increasing primary aluminium production, coupled with production disruption of the ore due to bauxite supply constraints. The imported alumina FOB...

Alumina price upswing complicates aluminium market dynamics, warns Trafigura

Alumina price upswing complicates aluminium market dynamics, warns Trafigura

The Trafigura Group, a key player in the commodity market, asserts that the surge in alumina prices significantly reshapes the outlook for aluminium prices. The price of alumina—derived from mined bauxite and used in aluminium smelting—skyrocketed by 50 per cent in 2024, reaching its highest level since March 2022. This sharp increase has been fuelled by production disruptions at alumina refineries and rising demand from aluminium smelters. Despite this, aluminium prices on the London Metal Exchange have remained relatively stagnant year-to-date. However, the escalating cost of alumina is placing significant financial pressure on smelters that don't have their own supply, potentially straining the broader industry. This growing commercial burden raises concerns about the long-term...

China's alumina capacity grows, fueling bauxite supply challenges

China is already home to more than 80 million tonnes of alumina capacity. So much so that the industry is struggling to source enough bauxite to satisfy demand. So, it's not particularly good timing for new alumina refining capacity to enter the market, but that's exactly what's happening. Markets change, of course, but built capacity rarely does. So perhaps the proprietors of new alumina capacity are hoping that the price will remain high but with better sources of ore coming their way. The problem is that China has a capacity cap of 45 million tonnes on primary metal, which equates to almost 90 million tonnes of alumina. Right now, the Chinese are also supplying Russia, but that's not a sustainable market. Eventually, the war will end, and sanctions will finally be lifted. However, the...
