What Is COMEX Aluminum Inventory?
COMEX aluminum inventory represents the total physical aluminum stored at CME Group-approved delivery points. Unlike precious metals (measured in troy ounces), aluminum is measured in metric tons. Stocks are categorized as warranted (available for delivery against futures contracts) and non-warranted (meets quality standards but not registered for delivery).
Why Aluminum Inventory Matters
Aluminum is essential for lightweight construction in automotive, aerospace, packaging, and electrical transmission. Global production exceeds 65 million metric tons annually, with China producing over half. COMEX inventory levels provide insight into North American supply conditions and can signal shifts in industrial demand or trade flows.
Frequently Asked Questions
- How is COMEX aluminum inventory measured?
- COMEX aluminum inventory is measured in metric tons. Stocks are divided into warranted (registered) and non-warranted (eligible) categories, stored at approved delivery points across the United States.
- What is the difference between warranted and non-warranted aluminum?
- Warranted aluminum has been registered with the exchange and is available for delivery against futures contracts. Non-warranted aluminum meets exchange quality standards but has not been registered for delivery. This is equivalent to the registered/eligible distinction for precious metals.
- How does COMEX aluminum compare to LME aluminum?
- The LME (London Metal Exchange) is the world's largest aluminum futures exchange with global warehouse locations. COMEX aluminum futures provide a North American benchmark. Traders monitor both exchanges to assess regional supply-demand dynamics and arbitrage opportunities.
- Why is aluminum inventory important?
- Aluminum is the world's most widely used non-ferrous metal, critical for transportation, packaging, construction, and electrical applications. Warehouse inventory levels reflect the balance between smelter production and industrial consumption, providing insight into market tightness.
