Metal Movers: The Global Aluminium Supply Squeeze

The latest episode highlights a dramatic shift in aluminium market dynamics, with European buyers now ranking supply security above sustainability and carbon‑border concerns. LME inventories sit at historic lows, creating a pronounced backwardation that reflects genuine shortages rather than demand spikes. Recent Middle‑East disruptions have amplified this scarcity, driving premiums above $4,000 per tonne and prompting buyers to scramble for reliable contracts amid a 50% Section 232 tariff that further inflates costs.

In the United States, the picture is equally tense. Prime aluminium supplies are projected to tighten over the next four months as pre‑war cargoes are exhausted. The UAE has surged to become the second‑largest U.S. supplier, but the 50% tariff forces many shipments toward Europe, intensifying competition for limited stock. Despite these pressures, demand destruction remains muted; packaging, automotive, and emerging energy‑transition sectors continue to rely on aluminium, with substitution pressures from copper and plastics appearing limited. Analysts forecast a global deficit approaching two million tonnes this year, suggesting sustained premium growth and limited price relief.

Looking ahead, new supply sources could temper the shock. Indonesia’s upcoming smelters promise additional primary aluminium, while Canada remains the U.S.’s primary trade partner, offering a nearby buffer. Domestic initiatives, such as Century’s 50,000‑tonne capacity restart in South Carolina, aim to reduce reliance on imports. However, even if Middle‑East stockpiles are released, elevated freight and insurance costs will keep overall pricing high. Stakeholders should monitor LME trends, tariff adjustments, and the pace of new capacity coming online to navigate this volatile environment.
