What Moves Aluminum Prices?

Power costs and smelter output

Aluminium smelting uses large amounts of electricity. Higher power costs or restrictions on electricity supply can reduce smelter output, while new capacity can increase supply. Changes in the availability of alumina, the smelter feedstock, can also affect production costs.

Construction, transport and packaging

Demand comes from buildings, vehicles and packaging. A slowdown in manufacturing can weaken orders even when energy costs are high. Exchange inventories give one view of available metal, but they do not capture every warehouse or regional shortage.

The surprise matters

A report can be positive for aluminum supply without causing prices to fall. If traders expected an even bigger increase, the result may support prices instead. Compare the news with the expectations already reflected in the market.

Match the timing to the trade. A development expected after your option expires may have less influence on its underlying futures month than on a later contract. Local cash prices can also differ from the exchange benchmark.

Connecting the outlook to an option

A manufacturer buying aluminium may use calls to help manage rising input costs. The LME price does not include every regional delivery premium.

Suppose you buy a call before a report and the price rises. You can still lose money if the rise is too small to cover the premium. If uncertainty falls after the report, lower implied volatility can also reduce the price available when selling the option.

A put faces the same timing problem in the opposite direction. Use an outlook to frame a possible trade, then calculate its premium, breakeven and expiry exposure. Aluminum Options provides the worked examples. Trading access and contract details explains what to check before choosing a contract.
