US aluminium market set to remain tight despite latest tariff changes
The US aluminium market remains constrained despite recent tariff adjustments aimed at boosting domestic production. Per the full note from ing-think, new investment incentives under the amended Section 232 tariffs are unlikely to significantly alter the market's reliance on imports, which keeps Midwest premiums elevated. The US domestic supply situation reflects a chronic shortfall, with only four primary aluminium smelters currently operational. This backdrop suggests that aluminium prices may face upward pressure in the near term as domestic production struggles to recover amid energy cost constraints and lingering import dependencies.
What the desk is arguing
The desk posits that the US aluminium market will continue to remain tight, driven by structural supply shortages despite recent policy shifts aimed at stimulating domestic production. Per the full note from ing-think, the limited operational capacity of US smelters and the substantial dependence on imports will likely prolong elevated aluminium premiums.
Supporting this view, US primary aluminium production has seen a steady decline over the years, dropping to just four operational smelters as of now, down from over 20 two decades ago. This structural shortfall suggests that even with potential future investments and relaxed tariff conditions, the market will remain under pressure for the foreseeable future.
Where it sits in our coverage
Given no specific internal target data for the relevant currencies, this section has been omitted to maintain clarity and focus on the core analysis.
How other firms see it
There is a divergence in views among firms regarding the outlook for aluminium prices, with some aligning with the desk's perspective on sustained tightness, while others see potential for a market correction. Bold firms aligned with tightening views include jpmorgan, speculating on the limited impact of tariff changes on overall supply dynamics.
Coupled with this, the closely watched price movements in the aluminium market may have indirect effects on currencies such as AUD/USD and CAD/USD, both of which are sensitive to commodity pricing. The dynamics of aluminium imports are likely to have implications for broader trade balances and subsequently impact these currency pairs.
What the calendar says
As there are currently no significant upcoming events in the calendar that pertain to aluminium dynamics or relevant policy shifts, this section has been excluded.

Key takeaways
- 01US aluminium market faces structural supply constraints.
- 02Recent tariff adjustments are unlikely to significantly boost domestic production.
- 03Midwest premiums are expected to remain elevated due to continued import reliance.
- 04Energy costs and investment hurdles constrain new smelting capacity development.
Market implications
Watch for potential impacts on aluminium-related assets or currency movements, especially if geopolitical developments affect supply chains. The near-term aluminium price dynamics could influence positioning in related currency pairs like AUD/USD.
Risks to this view
A significant reversal could occur if a major new source of competitive electricity becomes available for US smelters, drastically lowering production costs and enabling growth in domestic output. Additionally, further regulatory changes that incentivize capacity expansion could alter the current market dynamics.

Companies that build, expand or refurbish US smelting capacity can apply to import qualifying volumes at a 25% tariff instead of the standard 50% rate , provided they meet approved investment milestones. The shift reflects the limited success of tariffs alone in reviving US primary aluminium production.
US remains structurally short of primary aluminium US primary aluminium production has continued to decline over the years despite years of tariff protection. The country now has only four operating primary aluminium smelters, down from more than 20 at the turn of the century, leaving the US heavily reliant on imported metal. Canada remains by far the largest supplier of primary aluminium, while the Middle East also plays an important role in meeting US demand.

More fundamentally, primary aluminium production is constrained by access to reliable, competitively priced electricity rather than trade policy alone. While tariffs may improve project economics, developing new capacity still requires billions of dollars of investment, long-term power agreements, environmental permitting and several years of construction before additional metal reaches the market.

However, elevated Midwest premiums primarily reflect the combination of high import tariffs, limited domestic production and continued reliance on overseas metal.
We expect the US Midwest premium to remain well-supported. While the new programme may improve the longer-term outlook for domestic production, it is unlikely to materially reduce import dependence or procurement costs over the next several years.
