LME Aluminum Prices Fall: Market Shifts from Supply Shortage Concerns to Expectations of Supply Recovery

Aluminum prices on the London Metal Exchange (LME) fell by more than 4% from late September to early October 2026, as concerns over supply gradually eased and macroeconomic pressures intensified. The development indicates that the market is shifting its focus from the immediate risk of metal shortages toward the outlook for supply and demand balance over the coming months.

According to an analysis published by SMM on October 7, 2026, the LME cash aluminum price declined from US$3,248.5 per tonne on September 28 to US$3,107 per tonne on October 5, representing a decrease of 4.36%. On October 6, prices recovered slightly to US$3,134.5 per tonne. However, this rebound is not yet sufficient to confirm the emergence of a new upward trend.

Macroeconomic Pressures and Profit-Taking Weigh on Aluminum Prices

One of the main factors behind the decline in aluminum prices has been the macroeconomic environment. A stronger US dollar, persistently high interest rates, and profit-taking following a previous price rally have placed additional pressure on the industrial metals market.

With financing costs remaining elevated and the economic outlook still uncertain, investors have become more cautious about commodity positions. As a result, aluminum prices have become more vulnerable to corrections, even though the market’s underlying fundamentals have not yet indicated a clear surplus.

Notably, current price movements reflect a shift in market expectations. Rather than focusing solely on the risks of short-term supply disruptions, investors are increasingly assessing the possibility of supply restoration and the commissioning of new production capacity in the coming months.

Expectations of Supply Recovery Ease Shortage Concerns

Concerns about potential supply shortages had previously been one of the key factors supporting aluminum prices. However, expectations that supply in the Middle East will recover, plants will restart operations, and new production capacity will come online are prompting the market to reassess its earlier projections.

Indonesia is one of the regions attracting particular attention, as new capacity projects could add to global aluminum supplies. If the commissioning process proceeds smoothly, additional production could ease supply shortages and limit the potential for further price increases over the medium term.

Nevertheless, the actual pace of supply recovery will depend on the progress of plant restarts, production stability, energy costs, and the ability to deliver products to the market. Therefore, expectations of increased supply do not necessarily mean that the market will immediately shift into a surplus.

From a market analysis perspective, it is important to distinguish between designed production capacity, capacity that has actually entered operation, and output that can be commercially supplied. Only when additional capacity translates into stable commercial production is its price-dampening effect likely to become more evident.

Actual Demand Remains Too Weak to Support Prices

Alongside the supply outlook, actual purchasing activity remains a key constraint on aluminum’s recovery. Demand in China has been weaker than expected, while buyers have mainly been purchasing to meet immediate requirements rather than building inventories.

Cautious purchasing behavior suggests that companies are still weighing raw material requirements against price volatility and inventory risks. Without clear signs of improvement in end-user consumption, buying activity is unlikely to provide sufficient momentum to sustain a prolonged price rally.

Sluggish trading has also been observed in the Asian markets for aluminum scrap and secondary aluminum alloys. This development is particularly relevant to the metal recycling industry, as scrap procurement, secondary alloy production, and recycled raw material consumption are closely linked to demand from downstream industries.

When buyers limit inventory replenishment, scrap trading may remain subdued, forcing recycling companies to exercise greater caution in managing input materials, selling prices, and working capital turnover.

Inventories Remain Low, but Prices Fall as the Market Reassesses the Medium-Term Outlook

One notable feature of the latest correction is that aluminum prices have declined while inventory levels remain low. This indicates that price movements depend not only on the amount of metal currently available in the market but also on expectations regarding future supply and demand.

According to SMM’s analysis, market participants are increasingly focusing on the outlook for the next three to six months. The potential recovery of Middle Eastern supply, additional capacity in Indonesia, and slower-than-expected demand are changing investors’ assessments of the supply-demand balance.

In principle, commodity prices often reflect expectations about future market conditions rather than simply the state of supply at a particular moment. Consequently, aluminum prices can decline even when inventories have not increased significantly, if the market anticipates more favorable supply conditions or weaker-than-expected demand.

From the perspective of commodity market analysts, inventory data alone should not be used to determine the price trend. In addition to exchange inventories, the market needs to monitor off-exchange stocks, delivery activity, trade flows, and buyers’ ability and willingness to make purchases. These indicators provide a more comprehensive picture of the actual availability of metal.

For the recycling industry, the price movement also highlights the importance of closely monitoring the price differential between primary aluminum and aluminum scrap, as well as collection, sorting, smelting, and secondary alloy processing costs. A decline in LME aluminum prices does not necessarily translate into an equivalent decrease across all scrap grades, since actual transaction prices also depend on material quality, metal recovery rates, processing costs, and local supply-demand conditions.

Three Key Factors to Watch in the Coming Period

First, China’s purchasing activity following the holiday period. China plays a crucial role in global aluminum consumption. Trends in orders, manufacturing activity, and post-holiday raw material replenishment will help determine whether demand can recover sufficiently to support prices.

Second, aluminum exports and international trade flows. Changes in export volumes, the direction of metal shipments, and access to supplies in importing markets may affect the availability of aluminum in different regions. These developments will also help determine whether additional supply is genuinely easing market tightness or merely shifting between regions.

Third, the pace of supply recovery and the commissioning of new capacity. The progress of plant restarts in the Middle East, together with the commissioning of new projects in Indonesia and their transition to commercial production, will be important indicators. If output recovers faster than demand, aluminum prices may remain under pressure. Conversely, if the recovery process takes longer than expected or actual production falls short of projections, supply shortage risks could re-emerge.

Aluminum Price Outlook: US$3,100 per Tonne Remains a Key Level to Watch

SMM noted that the US$3,100-per-tonne level is providing a degree of support. The recovery from US$3,107 per tonne on October 5 to US$3,134.5 per tonne on October 6 suggests that buying interest emerged as prices approached this level. However, a single recovery session is insufficient to confirm a new upward trend.

In the coming period, the market is likely to remain sensitive to Chinese demand data, supply developments, and macroeconomic conditions. If purchasing activity improves while supply recovery remains slow, aluminum prices may find stronger support. Conversely, if demand remains weak and additional capacity enters the market as scheduled, downward pressure could persist.

For aluminum producers, traders, and recycling companies, the current environment calls for caution when making raw material purchasing decisions, managing inventories, and signing contracts. Adopting flexible procurement strategies, regularly monitoring LME prices, and tracking price differentials in local markets will help companies respond more effectively to unpredictable market fluctuations.

Overall, the price decline in early October 2026 does not necessarily mean that the aluminum market has entered a surplus cycle. The current movement reflects an adjustment in market expectations as supply shortage risks ease while actual demand has yet to demonstrate clear growth momentum. The next direction for aluminum prices will depend on how quickly supply recovers and whether demand is strong enough to absorb the additional metal entering the market.
