[SMM Aluminum Flash News] Rio Tinto and Century Aluminum Raise US Billet Premiums by Around 12%

Published: Apr 16, 2026 09:23
Rio Tinto and Century Aluminum raised US billet premiums by around 12%, about 3 cents/lb. (around USD 110/t) above pre-war levels. Middle East disruptions have affected supply from the Persian Gulf, which accounts for about 20% of US imports, tightening domestic supply. The US Midwest premium has reached a record USD 1.1325/lb., while aluminum prices have risen over 10% since late February. Amid growing uncertainty, buyers are shifting to domestic sourcing, while producers are pushing for long-term contracts to secure pricing and supply.
