SMM, August 3
According to SMM data, the average tax-inclusive full cost of the domestic electrolytic aluminum industry rose 0.9% month-on-month in July 2026, while falling 1.7% year-on-year, mainly driven by slight increases in the monthly average price of alumina, prebaked anode prices, and electricity prices during the period. The monthly average SMM A00 spot price in July (June 26 – July 25) stood at RMB 22,977 per tonne, down 4.2% month-on-month. Electrolytic aluminum profit margins narrowed by RMB 1,146 per tonne to RMB 6,999 per tonne, with average profitability up 56.8% year-on-year. Measured by the monthly average price, 100% of domestic operating electrolytic aluminum capacity was in profit in July.
By cost component:
Alumina: According to SMM data, the monthly average SMM Alumina Index in July (June 26 – July 25) was RMB 2,745 per tonne, up 1.6% month-on-month. Alumina prices fluctuated within a range through the month as inventories continued to accumulate; overseas alumina prices, however, rose on restocking ahead of production restarts and new capacity ramp-ups. Entering August, the alumina market is expected to maintain its current supply structure. Against a backdrop of net imports, there is no sign of an inflection point toward inventory drawdown, but cost support has lifted Guinean sellers' asking prices, lending upward momentum to alumina costs. In the near term, the tug-of-war between cost support and loose supply in the spot alumina market is set to continue. With prices relatively low at the start of the month, the August average price is expected to edge down slightly.
Auxiliary materials: In July, rigid demand from electrolytic aluminum underpinned domestic anode consumption, while export demand from Southeast Asia offset reductions in the Middle East, leaving the prebaked anode market relatively steady. Long-term contract procurement prices rose marginally by RMB 30 per tonne month-on-month. In the fluoride salt market, downstream buyers maintained rigid procurement and held off on purchases to push prices lower, leading to declines in procurement prices at major producers. Entering August, with cost support softening and supply continuing to expand, prebaked anode prices are expected to edge down slightly; fluoride salt prices, by contrast, are projected to rise on the back of rigid cost support combined with low operating rates. Overall, auxiliary material costs for electrolytic aluminum are expected to decline slightly in August.
Electricity prices: Electricity prices rose modestly month-on-month in July. Entering August, electricity prices are expected to remain broadly stable, and overall power costs for electrolytic aluminum are projected to hold steady.
In summary, the weighted average tax-inclusive full cost of SMM's domestic electrolytic aluminum industry rose slightly in July 2026; electrolytic aluminum costs are expected to decline modestly in August, with the average hovering around RMB 15,700–16,100 per tonne.
