APAC aluminium smelters are set to sustain strong margins as tight supply for global primary aluminium lifts metal prices, says Fitch Ratings. Low-cost producers in China, India and Indonesia are best placed to benefit because their integrated raw-material positions and relatively stable power costs should keep cost inflation contained.
Global primary aluminium supply is tightening as Middle East disruption removes metal from the seaborne market, and replacement supply remains limited. Prices have already responded, with aluminium prices rising around 20% since the beginning of the Iran conflict in late February 2026. This should support a windfall in earnings and cash flow for APAC smelters that can maintain output and control costs.
Fitch revised its Outlook on China Hongqiao (BB+) to Positive on 28 May 2026 due to its improved debt structure, strong profitability, robust cash flow generation, and solid industry fundamentals. It also upgraded Vedanta Resources to ‘BB-’ IDR on 2 April 2026, on higher commodity prices – especially for aluminium – and its improving cost structure with higher backward integration in aluminium. We also expect a positive impact for Chinalco’s (BBB+/Stable) financial profile from the current favorable market conditions, despite its IDR being top-down driven.
The ratings agency noted that APAC producers are better positioned than many global peers because their cost bases are less exposed to imported gas and spot raw-material volatility. China Hongqiao and Chinalco benefit from integrated bauxite-alumina-smelter chains and long-term raw-material access, which reduces earnings volatility when supply shocks hit. Their power mix also supports competitiveness: Hongqiao’s exposure to green electricity is around 40%, while Chalco’s aluminium capacity is supported by 55% power supply from green energy resources.
Smelter economics should remain favourable because alumina costs are not rising in line with aluminium prices. The restrictions on new smelting capacity in China are keeping alumina supply relatively loose, even after some operational disruptions, which should limit feedstock cost pressure. Fitch believes China is unlikely to ease the 45 million ton cap on primary aluminium smelting in the near term – given the sector’s intensive power consumption – and relaxing the restriction would jeopardise China’s effort in pushing for green transition for aluminium production. The combination of firmer aluminium prices and softer alumina costs is particularly supportive for integrated APAC producers.
Demand conditions should remain sufficiently supportive to preserve these stronger margins, even though China’s domestic economy is softer. Export-linked demand from electric vehicles (EVs) and other manufactured products remains a key offset to weak construction activity and slower domestic consumption. China’s EV exports jumped by 120% yoy in January-April 2026, while automotive exports rose by 61.5%.
Indonesia should add some regional aluminium supply, but not fast enough to loosen the market in the near term. Several projects are progressing faster than previously expected, yet power availability is likely to constrain output growth in late 2026 and early 2027. That bottleneck is already visible at Tsingshan’s Weda Bay Industrial Park, for example, where electricity is being reallocated from nickel pig iron operations to prioritise aluminium production, underscoring how captive power additions are lagging smelter expansion and helping to preserve support for prices and margins.
