The Aluminum Monthly Metals Index (MMI) rose 8.78% from January to February.
Since mid-January, LME three-month aluminum has shifted from a short-lived rally into a clear corrective phase.
During the second half of January, prices pushed higher, culminating in a notable spike around January 29, when aluminum hit a high of about $3,325/metric ton, 6% above its recent average. That move capped a brief upswing, and while the index appeared poised to break higher, the advance quickly exhausted itself.
The market reversed into a bearish trend from that peak. Prices rolled over in late January and then tracked steadily lower into early February. Analysts noted two distinct trend reversals around January 29 and February 3, both of which signaled a loss of upward momentum. Over the past month, aluminum has fallen from roughly $3,160/metric ton down to around $3,040/metric ton, a decline of about 4%. This places the metal near the lower end of its recent trading range. Notably, volatility over this window had been moderate. Rather than a crash, there has simply been a controlled grind lower.
Technically, the picture has been bearish since mid-January. The latest analysis shows aluminum pressing into short-term support around $3,040/metric ton, with additional support just above $3,110/metric ton and nearby resistance clustered in the high $3,100s. In other words, the market has moved from testing the upper end of the range in late January to probing support in early February. Sellers are now in control, with buyers only stepping in around key support levels as opposed to driving a sustained rally.
Investment fund positioning in the aluminum market has softened at the margin, with managed money reducing long exposure while simultaneously adding to short positions. Although the absolute change in positioning through the end of January remains modest, the direction of travel is notable. After a period in which speculative participation broadly supported base metal prices, the shift suggests that some investors are beginning to reassess the durability of the recent aluminum price rally.
At this stage, the repositioning does not yet point to a decisive bearish turn. Net length remains broadly intact, and the scale of the reduction in longs, alongside the increase in short bets, is still limited relative to historical swings in fund activity. As a result, current positioning should be interpreted more as a cautious recalibration than an outright reversal in sentiment. This is particularly evident given that fundamental supply tightness and cost support remain key features of the aluminum market.
That said, if the trend of declining long exposure and rising short interest continues into February, it would signal a more meaningful change in speculative conviction. A sustained build in short positions would imply growing skepticism around near-term demand strength and the ability of tight physical conditions to keep prices elevated. In that scenario, fund flows could shift from being a marginal source of price support for aluminum to a potential headwind.
Although China’s aluminum production caps are often cited as a key structural support for the global aluminum market, their practical importance to near-term supply is frequently exaggerated. In reality, China has been operating close to its policy-imposed capacity ceiling for several years. This means the cap functions more as a formal constraint on new greenfield expansion rather than a binding limit on current output growth. As a result, changes in operating rates, restarts and regional production shifts within the existing capacity base tend to have a much larger influence on effective supply than the headline cap itself.
The way production is managed inside China further dilutes the impact of national caps on global availability. Capacity can be retired in one province and effectively replaced elsewhere through approved “capacity swap” programs. These allow new, more efficient smelters to start up without breaching the national ceiling. In turn, this has enabled continued growth in realized aluminum output despite the apparent stability of total nameplate capacity. In practice, the cap shapes where and how aluminum is produced—often favoring low-cost, energy-advantaged regions—rather than acting as a hard stop on supply.
Finally, even if the national cap limits future Chinese expansion, it will not necessarily tighten the global aluminum balance as much as markets often assume. China can still influence international supply through higher exports of semi-finished products and the growing integration of overseas smelting and alumina capacity by Chinese producers. Together with improvements in operational efficiency and higher utilization rates at existing smelters, these channels mean that global aluminum availability can continue to expand even in a policy environment where China’s headline primary aluminum capacity appears capped.
Last year’s large fire at the Novelis aluminum plant in Oswego, New York, continues to have ripple effects well into 2026. The facility, which supplies a significant portion of automotive-grade aluminum used by U.S. car makers (including for Ford’s flagship F-Series trucks), has not fully resumed output more than four months after the September blaze. This follows a second fire in late November, which further delayed the restoration of operations and undermined expectations that production would be largely back online by year's end.
For the U.S. aluminum market, this prolonged outage highlights vulnerabilities in domestic supply concentrations. Because the Oswego plant plays a central role in producing automotive-grade aluminum sheet, its partial shutdown has constrained the domestic supply pool and forced buyers like Ford to source metal from other Novelis facilities and alternative global suppliers. Relying more on foreign production to fill gaps can be costly and time-consuming, especially given the tariffs on imported semi-finished aluminum products, which can add an estimated 50% to landed costs. The latter is a pressure analysts have frequently pointed to in the context of U.S. supply challenges and cost inflation for downstream manufacturers.
This tighter supply situation has broader implications for pricing dynamics in the U.S. primary and rolled aluminum markets. Limited capacity at a major domestic mill tends to support higher spot and contract prices as buyers compete for available material and increasingly turn to imports. As of February, the Midwest Premium remains in an uptrend, climbing above the $1/lb mark and far-surpassing initial estimates for its peak.
For end users like automakers and other industrial consumers, higher aluminum costs feed into broader production costs. In turn, this can affect profit margins, production planning and even vehicle pricing in downstream markets. The situation also highlights the strategic importance of supply chain resilience in the U.S. metals sector. A single event that disrupts such a large share of a specialized product underscores the risks associated with concentrated processing capacity. Discussions around bolstering domestic rolling capacity, diversifying supply sources and encouraging investment in resilient infrastructure are likely to intensify as market participants respond to both the immediate disruption and longer-term competitiveness concerns.
As of mid-January, investor sentiment appears decisively positive. Data from the LME’s aluminum Commitment of Traders Report shows that among investment funds, both net positioning and long positions sit at their highest level since at least 2020.
These trends indicate that speculation is once again a dominant force in the aluminum market. Elevated fund length suggests investors are positioning for further price upside, driven by expectations of tighter supply conditions, supportive macro signals and the potential for additional policy- or energy-related disruptions. As a result, near-term price action may be increasingly influenced by financial flows rather than by underlying physical demand alone, raising the risk of heightened volatility should sentiment shift.
However, it remains worth noting that a shift in investor sentiment could reverse quickly if macroeconomic conditions deteriorate or if physical market fundamentals fail to validate bullish expectations. Any signs of weakening demand, easing energy costs or an improvement in supply availability could prompt funds to unwind long positions, amplifying downside price risk. Consequently, while speculative interest currently supports aluminum prices, the market remains vulnerable to sharp corrections if confidence falters.
