Though a plethora of speed breakers hit the aluminium industry in recent times, global primary aluminium operating capacity is set to rise sharply. SMM, through one of its recently held webinars, projects an increase of about 20.9 million tonnes by the end of 2026, taking total operating capacity to roughly 77.16 million tonnes, with Indonesia among the largest incremental contributors.
Global primary aluminium production in 2025 grew marginally to approximately 73.78 million tonnes, up from 73.01 million tonnes in 2024, representing a 5-year low in growth rate. China, holding a 45 million tonne capacity cap, operated at nearly 97 per cent capacity (approx. 43.9 million tonnes) in 2025, limiting global growth, with the market facing continued supply deficits.
