Aluminum Market Faces Severe Supply Squeeze
TREE NEWS reports: London Metal Exchange (LME) aluminum inventories have plunged 56% this year to their lowest level since 1990, triggering a sharp rise in cash premiums and leaving buyers with little relief in sight. The cash-to-three-month spread widened to $92 per tonne on Monday, approaching multi-year highs last seen during the Middle East conflict earlier this year. The benchmark three-month aluminum contract settled up 0.1% at $3,066.50 per tonne, while copper rose 0.9% to $13,896.50.
Physical Market Extremely Tight
The collapse in LME stocks has created a classic backwardation structure, where spot prices trade above forward contracts, reflecting acute scarcity at the prompt delivery end. “This backwardation is a real reflection of how tight the physical market is. There aren’t many obvious sources of metal that can quickly flow into the LME,” said Ewa Manthey, commodities strategist at ING. The squeeze is compounded by ongoing supply disruptions from the Middle East, where attacks on smelters have kept some facilities offline, and by trade barriers in the US and Europe that have tightened local availability.
Indonesian Supply Offers Long-Term Hope, But Not Immediate Relief
Indonesia’s aluminum production is ramping up and is expected to push the global market into surplus in the coming years, weighing on prices. However, Indonesian metal has not yet completed LME delivery registration, so it cannot directly replenish exchange warehouses. Meanwhile, European and US end-users are paying hefty premiums over futures to secure spot metal, incentivizing producers to sell directly rather than deliver to the LME. “This means cash premiums may need to widen further to attract metal into LME warehouses. But in the medium to long term, we see more downside risk for aluminum prices,” Manthey added.
Long Positioning Raises Squeeze Risk for Shorts
LME data shows four unnamed long position holders collectively hold at least 25% of open interest in the November aluminum contract, which expires next week. The key question is how wide the cash premium must become to encourage these longs to roll their positions and give relief to shorts who may struggle to secure metal for delivery. For shorts, the backwardation means rolling contracts incurs losses, creating a substantial squeeze risk, while longs can earn attractive returns from rolling. The LME forward curve suggests tightness could persist for months, with backwardation potentially extending to 2028.
Market Implications
- Stocks: Aluminum producers and smelters could see margin expansion, but downstream manufacturers face higher input costs. Mining and metals equities may outperform as physical premiums rise.
- Bonds: Limited direct impact, but persistent commodity inflation could influence central bank policy expectations.
- Crypto: No direct link, though commodity-backed tokens may see increased interest as a hedge against physical tightness.
- Commodities: Aluminum remains supported near-term by the squeeze, but the looming Indonesian surplus caps longer-term upside. Copper’s gain reflects broader base metals strength.
- Currencies: Commodity-linked currencies like the Australian and Canadian dollars may find support from elevated metals prices.
Key Takeaways for Investors
- The aluminum market is experiencing a severe near-term squeeze, with LME stocks at 30-year lows and cash premiums near multi-year highs.
- Physical tightness is exacerbated by Middle East supply disruptions and trade barriers, with Indonesian supply unable to immediately fill the gap.
- Concentrated long positions in the November contract raise the risk of a short squeeze, potentially increasing volatility.
- While near-term prices may stay elevated, the medium-term outlook points to surplus and downside risk as Indonesian production ramps up.
- Investors should monitor LME inventory flows and the cash-to-three-month spread for signs of easing or further tightening.
