Global aluminium market: Aluminium inventories tighten, but rising supply is expected to cap a sustained price breakout

Overview

This global aluminium dashboard examines production, demand, inventories, prices, costs and producer valuations. JPMorgan highlights a sharp inventory draw and resilient Chinese consumption, but argues that forthcoming supply growth should limit a fundamentals-driven price rally as the market approaches balance.

Core views

Global aluminium production and demand were both down 1% year to date through August. Chinese production increased about 2%, running just above the 45Mtpa capacity cap, while production outside China declined 5%; the Middle East accounted for a particularly large reduction of almost 3Mtpa annualised since April. Demand showed the same divergence: China consumption rose 2%, offset by a 5% decline in the rest of the world. JPMorgan also flags drought conditions in Yunnan, a province producing roughly 6Mt of aluminium, as a hydro-power-related supply issue to monitor even though it sees no imminent stress. The immediate market is tighter than the annual demand figures imply. Global visible aluminium inventories fell about 900kt from a mid-May peak near 1,840kt to 920kt in late September, including a substantial Shanghai Futures Exchange draw from about 1,400kt in May to roughly 700kt. Total inventories were below the comparable seasonal level of the preceding five years. Aluminium was up 8% year to date and prices were near marginal costs, but JPMorgan says the forward curve remained in backwardation because the market expects future supply growth. The report argues that tight spot inventories are being offset by expectations of recovering Middle Eastern output and rising Indonesian production. Prices have stayed within US$3,200–3,400/t since early August, and JPMorgan expects the market to move toward balance by 4Q26, with a balanced market anticipated for 2027. Its supply-demand balance table indicates a 2026E deficit of 1,665kt, a near-balanced 2027F deficit of 28kt, and an 848kt surplus in 2028F. Indonesian production is shown increasing by about 2.6Mt between 2025 and 2028, underpinning the projected 2028 surplus and limiting scope for fundamentals-driven outperformance. Potential upside is described as copper-led rather than stemming from aluminium fundamentals alone. A high copper-to-aluminium ratio could encourage investor rotation into relatively cheap aluminium and raise expectations for substitution demand. The report also notes that a reopening of the Chinese semi-export arbitrage could produce temporary front-end backwardation, but is unlikely to create a sustained curve-wide rally. For equities, JPMorgan identifies Rio Tinto, Hindalco, Vedanta and Press Metal as key Overweight positions. The coverage universe trades at an average 7.0x 2027 EV/EBITDA and 6.8x 2028 EV/EBITDA, with average dividend yields of 4.3% in both years. It recently downgraded Norsk Hydro to Neutral because of energy-cost concerns at the Alunorte refinery in Brazil; the team is concerned about potential spot-LNG purchases in 4Q and estimates 3Q and 4Q EBITDA about 10% and 12%, respectively, below Bloomberg consensus, placing the company on negative catalyst watch into its 3Q results.

Analysis framework

JPMorgan combines regional production and demand data, inventory and forward-curve indicators, long-term supply-demand forecasts, marginal-cost and cost-curve analysis, and relative valuation comparisons across aluminium producers. It then links expected regional supply changes and Chinese consumption trends to commodity-price implications and covered-equity positioning.

Impact & implications

The report views current inventory tightness as supportive but not sufficient for a durable aluminium-price rally because anticipated Middle Eastern recovery and Indonesian capacity growth should rebalance the market. It favors selected producers while identifying Norsk Hydro's energy-cost exposure as a near-term concern.

Risks

• Yunnan drought could create hydro-power-related supply stress for a province producing about 6Mt of aluminium.
• A high copper-to-aluminium ratio could trigger investor rotation into aluminium and raise substitution-demand expectations.
• Norsk Hydro faces potential additional spot-LNG costs in 4Q at its Alunorte refinery.

What to watch

• Whether Yunnan drought conditions begin to affect hydro-power availability and aluminium output.
• The pace of Middle Eastern production recovery and Indonesian supply growth.
• Visible inventory trends, including Shanghai Futures Exchange stocks.
• Whether the Chinese semi-export arbitrage reopens and affects front-end backwardation.
• Norsk Hydro's 3Q results and 4Q energy-cost outlook.
