Alcoa Supply Risk Rises as Gulf Output Halts, LME Jumps 6%
Strikes on two Persian Gulf smelters disabled 3.2 million tons of annual aluminium output, triggering a 6% rise in LME benchmark prices and a 63% surge in European billet premiums. Global stocks have drawn down to around 45 days of consumption, raising acute supply concerns.
1. Strike Details and Output Loss
Iran’s attacks disabled two Gulf smelters with combined capacity of 3.2 million tons per year, representing over half of regional output and creating an immediate supply void for major producers like Alcoa.
2. Price Reactions
London Metal Exchange aluminium prices jumped 6% on the first trading day post-strike and European billet premiums soared 63%, signaling intense competition for physical metal.
3. Inventory Impact
Tightened supply has drawn down LME inventories to roughly 45 days of consumption, near multi-year lows, heightening risks of acute shortages and production slowdowns.
4. Implications for Alcoa’s Operations
Higher spot prices and supply uncertainty could inflate Alcoa’s raw material costs and limit smelter throughput, potentially constraining revenue and profit margins if normal shipping routes remain blocked.
