Aluminum powered toward $3 000 a ton amid expectations that supply disruptions are here to stay, while demand keeps rising.

The metal notched yet another 13-year high on Monday after rising 15% over the last three weeks. Chinese output is down amid drives to reduce emissions and conserve power, while a coup in bauxite producer Guinea has raised concerns over the supply of the material used in aluminum production. Smelters in the European Union are also facing rising costs with both carbon credit and power inputs at record highs. Goldman Sachs Group said.

“In China and increasingly in the EU, policy risk to aluminum supply is growing,” Goldman analysts including Jeff Currie said in a note released Monday. While the bank doesn’t see the recent coup in Guinea as materially impacting bauxite, upside risks remain as regional tensions could generate further logistical bottlenecks, they said.

Aluminum Corp. of China Ltd., the country’s largest smelter, surged as much as 12% in Hong Kong on Monday. Chinese material equities may see a further re-rating as more government moves to curb steel production to cut emissions could boost prices for cement, steel and aluminum, Citigroup Inc. analyst Jack Shang said in a note.
