UBS believes the China aluminum sector is overly pessimistic, and the valuation reset offers dip-buying accumulation opportunities

Overview

This report focuses on the China aluminum sector and global primary aluminum supply-demand. UBS believes the market’s concerns over excess Chinese aluminum supply and global aluminum oversupply are excessive. In China, although high margins are driving electrolytic cell upgrades, delayed maintenance, and parallel operation during replacement, utilization rates nationwide continue to fluctuate around 100%, and policy capacity limits and operational constraints still restrain supply expansion. Overseas, Indonesia is the main source of incremental supply, but medium-term releases are constrained by power availability, power allocation between aluminum and nickel, and policy uncertainty; about 3mt of Middle East capacity has been disrupted and restart will take time. The report therefore concludes that sector fundamentals have weakened versus prior periods but have not deteriorated into material oversupply, and valuation compression has created a buying opportunity.

Core views

Core views include: first, China will not abandon the 45.43mt cap and revert to the unrestrained expansion model of 2009-2017, with 2026E and 2027E output rising only modestly to 45.6mt and 46.0mt. Second, the global aluminum market remains short 1.1mt in 2026E and returns to balance in 2027E after supply growth of more than 3mt, but not to a state of significant oversupply. Third, China demand in 2026E weakens under pressure from real estate, photovoltaics, and home appliances, but net exports, vehicle light-weighting, machinery sales, power grid investment, and copper-aluminum substitution provide support, with total demand seen as flat in 2026E and up 2% in 2027E. Fourth, despite lower aluminum price forecasts, industry earnings remain healthy, with China aluminum cash price spreads expected to stay above Rmb6,000/t in 2026E and above Rmb5,000/t in 2027E. Fifth, Hongqiao, Chalco, and Tianshan remain attractive on earnings, dividends, or output growth.

Analysis framework

The report uses a top-down aluminum supply-demand balance framework and combines it with company earnings and valuation models. On the supply side, it breaks down China’s approved capacity, replacement capacity, electrolytic-cell efficiency, maintenance, and overseas new output; on the demand side, it splits demand into real estate construction, transportation, power, packaging, home appliances, machinery, and exports. On the price side, it incorporates LME, SHFE discount, supply-demand deficits, cost curves, and copper-aluminum ratios. On the company side, target prices are derived from earnings forecasts, target PEs, and target dividend yields.

Methodology notes

• Supply-demand researchAluminum supply-demand balance model

  Uses capacity, output, inventories, imports/exports, and end-demand to estimate market deficit or surplus.

  UBS treats China, Indonesia, and the Middle East as key supply variables, and real estate, transportation, power, packaging, home appliances, machinery, and exports as demand variables, concluding that the global market remains short in 2026 and moves toward balance in 2027.

• Valuation researchTarget PE and target dividend yield valuation

  Uses earnings multiple or dividend yield as target valuation anchors for each company.

  Tianshan and Chalco use a constant target PE, while Hongqiao uses a 6.5% target dividend yield; although earnings forecasts and target prices are lowered, valuation still implies strong upside.

• Scenario and sensitivity analysisEarnings sensitivity analysis

  Assesses the impact of changes in aluminum prices, margins, and valuation on company net profit, PE, and dividend yield.

  The report provides 2026E and 2027E earnings sensitivity charts to gauge how much company earnings and valuation are pressured after aluminum price reductions.

  Risks

  Supply recovery faster than expected, persistent demand weakness, and changes in speculative positioning.

Key data

• China approved aluminum capacity ceiling45.43mtDerived from the 2017 supply-side reform; UBS believes this ceiling is still valid.
• China aluminum production forecast2025 44.5mt; 2026E 45.6mt; 2027E 46.0mtSlightly above nominal approved capacity, but does not imply the production cap is ineffective.
• Global aluminum market balance2026E shortage of 1.1mt; 2027E returns to balanceNew supply from Indonesia and Middle East restarts ease tightness but do not constitute a material surplus.
• Indonesia incremental output2026E +1.0mt; 2027E +1.7mtDriven by Tsingshan, Xinfa, ADMR, Nanshan and related projects, but constrained by power and policy in the medium term.
• Middle East supply disruption2026E net production impact -2.8mt; 2027E recovery +1.1mtAbout 2.7-3.3mt of capacity is affected, and some assets may need over 12 months to fully restart.
• China demand forecastFlat in 2026E; +2% in 2027EReal estate, photovoltaics, and home appliances are pressured, while exports, transportation, machinery, and power grid investment provide support.
• China aluminum price forecast2026E Rmb23,000/t; 2027E Rmb22,500/tBased on 2026E/2027E SHFE/LME discounts of 9%/5%.
• Global aluminum price forecast2026E US$1.50/lb; 2027E US$1.42/lb2027E forecast has been lowered, reflecting reduced supply-demand tightness.
• Earnings forecast adjustmentTianshan, Chalco, Hongqiao 2026E/2027E earnings cut by 9%-15%/24%-33%Mainly due to lower aluminum price assumptions and a softer supply-demand outlook.
• Target price adjustmentReduced by about 19%-21%Core valuation assumptions are largely unchanged, but the earnings base has been revised lower.

Impact & implications

The investment implications are constructive: market pricing of supply oversupply and weak demand appears overly pessimistic, and aluminum prices and company earnings retain upside if China maintains capacity discipline, Indonesia expansion remains constrained, or Middle East restarts are delayed. For equities, Hongqiao benefits from high dividends and buybacks, Chalco from margin improvement, and Tianshan from output growth and high profitability. For the commodity itself, aluminum prices may have fallen from prior highs but are still expected to remain above the cost curve.

Risks

• If China relaxes capacity limits or production above the cap rises beyond expectations, supply could be significantly above forecast.
• If Indonesian projects see resolved power bottlenecks and policy becomes more supportive of expansion, global supply increments could exceed expectations.
• If disrupted Middle Eastern capacity restarts faster than expected, the 2026 global deficit could narrow.
• If China real estate, photovoltaics, home appliances, and domestic demand continue to weaken, aluminum demand may undershoot forecasts.
• Export arbitrage may be constrained by tariffs, logistics, buyer bargaining power, and declining offshore premiums, limiting compensation for weak domestic demand.
• Aluminum prices below the Rmb23,000/t or Rmb22,500/t forecasts would compress company earnings and dividend capacity.
• Cost volatility in power, alumina, and coal may affect aluminum cash spreads.
• Even with unchanged valuation assumptions, a weaker market risk appetite could limit target price realization.

What to watch

• Progress of enforcement actions against illegal overproduction in China, closure of non-compliant capacity, or formalization developments.
• Whether China’s monthly aluminum output and Aladdiny and Mysteel utilization rates continue to oscillate around 100%.
• Ramp-up pace of Indonesian Tsingshan/Xinfa, Weda Bay, ADMR, Nanshan, Harita, and Bosai projects.
• Whether the shift of nickel power to aluminum projects in Indonesia persists, and how power allocation changes as nickel margins recover.
• Restart pace of Middle East capacities including Al Taweelah, Alba, Qatalum, Jebel Ali, and Iran.
• Changes in LME-China spreads, export tariffs, logistics costs, and offshore aluminum product premiums.
• China property starts, photovoltaic installations, auto exports, machinery sales, and power grid investment data.
• SHFE/LME discount, copper-aluminum ratio, and aluminum industry cash spreads.
• Execution of Hongqiao dividends and buybacks, Chalco margin improvement, and Tianshan delivery of output growth.
