In Q1 2025, alumina prices dropped considerably by $599 per metric ton FOB Shanghai, or a 20.66% decline. The decline followed a prolonged period of sustained price increases in 2024 and was largely caused by relaxing supply bottlenecks and an easing in downstream demand. Favorable weather patterns in key producing countries like Australia and Guinea enabled recovery in mining and refining production, leading to improved inventories.
Simultaneously, demand eased marginally as global aluminum producers reduced output to cope with lofty input costs and higher recycling levels. Market correction also mirrored speculation about unwinding and better shipping availability, which relieved earlier logistical strains.
According to the PriceWatch, In Q2 2025, alumina prices experienced significant declines in both Australia and China due to a combination of supply rebounds, global market shifts, and policy changes. In Australia, the alumina price dropped sharply to $355 per metric ton FOB Brisbane, marking a 28.72% decrease from the previous quarter.
This steep fall primarily reflects a rebound in supply following major output curtailments in 2024, including the closure of Alcoa Kwinana refinery and a force majeure event at Rio Tinto Queensland operations. Additionally, the relaxation of antidumping duties in key export markets has weakened demand for higher cost Australian alumina.
Meanwhile, China alumina price fell to $451 per metric ton FOB Shanghai, down 24.79% quarter on quarter. The decline is largely attributed to oversupply from significant capacity expansions, with more than 13 million tons of new refining capacity coming online in China, along with large-scale projects in Indonesia and India flooding the global market.
In Q3 2025, the global alumina market experienced a mixed but modest upward trend of 2–3% in prices compared to the previous quarter, driven by a combination of supply-side developments and regional demand variations. New supply additions from Indonesia and India continued to pressure the market, while localized production curtailments, especially in China and Australia, helped balance some of the oversupply.
At the same time, bauxite supply risks, particularly from Guinea, and logistical disruptions added short-term volatility. Demand growth remained steady but subdued, closely tied to aluminium production trends, which faced regional constraints. Overall, the market reflected a structurally loose supply environment, with prices largely fluctuating near cost floors, and any gains remaining fragile and regionalized rather than broad-based.

According to PriceWatch, in Q3 2025, the alumina price trend in China experienced a slight decline resulting in a 0.83% decrease compared to Q2 2025. Market sentiment was cautiously subdued as supply growth from new production capacities outpaced downstream demand from the aluminium smelting sector, which remained stable but constrained by capacity limits and muted export demand.
Raw material costs including bauxite and caustic soda were relatively stable, providing limited upward pressure on prices. However, alumina prices rebounded modestly in September 2025 with a 0.64% increase, supported by tightening supply conditions as some high-cost producers reduced output and inventories began to normalize.
Export activity offered minimal support during ongoing global demand uncertainty. Overall, the alumina market in China during Q3 2025 reflected a slight oversupply environment with prices trending downward initially but showing signs of stabilization heading into the final quarter of the year.

In Q3 2025, the alumina price trend in Australia experienced a slight price increase of 3.68% compared to Q2, reflecting a cautiously positive sentiment amid tightening supply and steady demand growth. The uptick was driven by a combination of constrained bauxite availability impacting refining operations and elevated raw material costs, particularly energy and transportation expenses, which pressured producers to adjust output levels strategically.
Export activity stayed robust, supported by sustained demand from key Asian markets, though logistical challenges intermittently affected shipment volumes. Notably, alumina prices rebounded modestly in September 2025 with a 0.64% decrease, attributed to short-term inventory corrections and mild softening in downstream alumina consumption.
As a whole, the market outlook heading into Q4 2025 suggests continued price resilience, underpinned by supply-side constraints and stable demand, although potential volatility remains as producers navigate cost pressures and global economic uncertainties.
The international alumina market saw an increase in prices for the fourth quarter of 2025 (approximately 8 – 9%) compared to the third quarter of 2025, due to stronger supporting fundamentals. The stability of the countries’ economies have also a contributing factor to moving upward in price.
Factors causing an upward trend included continued discipline by refineries in their operations and a tightness in the spot market for availability of alumina. Refineries experienced extended maintenance turnarounds, and energy price volatility from key production areas caused an increase in operating costs as well as limited possible output growth.
Seasonal restocking at smelters, along with normal levels of alumina production, resulted in consistent feedstock demand for alumina. Freight constraints and longer lead times have led to a reduced supply of prompt cargoes, particularly in Asia.
Overall, the supply and demand dynamics have been more balanced at the end of the fourth quarter than they have been at the end of the third quarter, allowing producers to regain their pricing power through the strengthening of regional premiums and an overall price increase for alumina trading hubs worldwide.
According to Price-Watchâ„¢, In Q4 2025, the global alumina market experienced a moderate correction, with prices declining by approximately 5.2% compared to the previous quarter. The downturn was primarily driven by improved supply availability from key producing regions such as Australia and China, where refinery operating rates increased following earlier maintenance shutdowns.
At the same time, demand from the alumina smelting sector softened slightly as downstream consumption slowed in major industrial economies, including China and United States.
Additionally, easing energy and logistics costs helped reduce overall production expenses, further contributing to downward pressure on prices. However, the market remained relatively supported by stable long-term demand from the alumina industry and steady procurement activity. Overall, the quarter reflected a rebalancing phase in the global alumina market as supply conditions improved and demand growth moderated.
