Rio Tinto and Century Aluminum Raise U.S. Billet Premiums by About 12%

Rio Tinto Group and Century Aluminum Co. have increased premiums on aluminum billets in the United States by roughly 12%, equivalent to about 3 cents per pound or $110 per ton above pre-war levels. The move follows disruptions to imports from the Middle East tied to the Iran war and is accompanied by efforts to secure customers into multiyear contracts at the elevated rate. The shift has tightened available domestic supply and contributed to higher regional benchmark premiums and broader aluminum price gains.

Key Points

Rio Tinto and Century Aluminum raised U.S. aluminum billet premiums by about 12% - approximately 3 cents per pound, or $110 per ton above pre-war levels.
Disruptions to Persian Gulf exports, which represent nearly 20% of U.S. aluminum imports, have pushed buyers toward the domestic market where supplies are tight and prices are higher.
Aluminum prices have climbed over 10% since the Iran war began in late February; the U.S. Midwest premium reached a record $1.1325 per pound.

Two leading suppliers to the U.S. market, Rio Tinto Group and Century Aluminum Co., have raised premiums on aluminum billets by approximately 12% - a move that translates to roughly 3 cents per pound, or about $110 per ton, above levels seen before the onset of conflict in Iran.

Producers are transferring the higher premium to buyers at a time when flows from the Persian Gulf have been disrupted. Those Middle East exports account for nearly a fifth of U.S. aluminum imports, and interruptions in those shipments are prompting U.S. purchasers to look to domestic suppliers instead. Domestic inventories already face tightness, and sourcing locally carries a price premium versus pre-disruption import channels.

Rio Tinto is also pressing its customers to accept multiyear contracts that lock in the higher premium, a commercial posture that would secure revenue visibility for the supplier while transferring price exposure to counterparties over a longer horizon.

The pricing environment has moved noticeably since the conflict began. Aluminum values have climbed by more than 10% since the Iran war started in late February. At the same time, the U.S. Midwest premium - the regional uplift added to global benchmark prices for delivery into that sector - has reached an all-time high of $1.1325 per pound.

Those developments reflect two connected dynamics described by market participants: reduced inbound flows from the Persian Gulf, and a domestic market where available metal is scarcer and therefore more expensive. Buyers responding to import disruption by sourcing within the U.S. are encountering both higher spot rates and supplier efforts to extend commitments through multiyear deals at the raised premium.

The immediate outcome is a higher cost basis for aluminum billet in the U.S. market and record regional premium levels. How long these conditions persist will depend on the evolution of import flows and the balance between domestic supply and demand, as well as commercial acceptance of longer-term contracts at the elevated pricing.

Risks

Continued disruption to Middle East supply could sustain elevated premiums and tighter domestic availability - impacting sectors reliant on aluminum such as manufacturing and industrial goods.
Pushes by suppliers for multiyear agreements at higher rates may lock buyers into increased input costs, creating contractual exposure for downstream producers and purchasers.
Higher regional premiums and rising global aluminum prices raise cost pressures that could transmit through supply chains, affecting industries where aluminum is a significant input.
