Strait of Hormuz shipping disruptions and regional plant actions pushed LME aluminum to roughly $3,544/t, tightened U.S. ingot availability with an 8% jump, and lifted Indian producers’ shares as inventories fell to multi-year lows.

A week of concrete supply moves and energy-driven strategy shifts pushed aluminum to multi-year highs. Mozal’s mothballing, dollar weakness, and Alcoa’s electricity pivot are tightening near-term fundamentals while analysts diverge on 2026–27 balances.

Recent, concrete supply disruptions — South32’s planned Mozal smelter mothballing and the Novelis Oswego plant fire — have tightened physical aluminum availability and lifted premiums, while tariff-talk and uneven sector demand add volatility and directional risk for investors.

A sharp squeeze in physical supplies pushed U.S. Midwest premiums above $1/lb and sent LME aluminum to multi‑year highs. Tight inventories, constrained new capacity and accelerating demand from energy storage are driving a near‑term structural deficit that favors low‑cost, integrated producers and spot‑focused trading strategies.

Last week's developments pushed aluminum pricing dynamics in two directions: a sharp post-New Year inventory build in China that could temper near-term prices, and a high-profile Oklahoma smelter joint venture that signals meaningful U.S. primary supply growth further out. Tighter trading rules on the Shanghai Futures Exchange and new U.S. alloy capacity add to the mix, creating a nuanced outlook for producers, buyers and traders.

Aluminum prices have jumped toward $3,200/ton driven by the Mozal smelter shutdown, EU CBAM-driven premiums, tightening inventories and energy-driven European supply losses—creating a sustained supply squeeze with clear implications for premiums, hedging and near-term price volatility.
