Aluminium prices in India have come under downward pressure in October 2026, with domestic prices falling as a combination of global supply recovery and elevated Chinese aluminium exports weigh on the LME. A stronger US dollar adds a further headwind to commodity prices denominated in dollars. For Indian foundries and casting units that purchase secondary aluminium ingot priced with reference to LME, this price movement is a development with immediate operational implications — one that cuts both ways depending on how a foundry's cost and pricing structures are set up.
The Supply Recovery Dynamic
Global aluminium supply has been recovering through 2026 after a period of production disruptions and curtailments in prior years. Smelters in China — which account for over half of global primary aluminium production — have been running at high utilization rates, and new capacity that was commissioned in earlier years is now fully operational. Outside China, production in the Gulf region (Aluminium Bahrain, EGA in the UAE) and in India (Hindalco, Vedanta) has also been stable to growing. When supply recovers broadly, the upward price pressure that characterized tighter periods dissipates, and the market moves toward equilibrium or modest surplus — conditions that translate into softer LME prices.
China's Export Position
China's role in global aluminium trade is structurally significant. While China is not a net exporter of primary aluminium ingot in the traditional sense, it exports large volumes of semi-fabricated aluminium products — extrusions, rolled products, and castings — that effectively export aluminium content in processed form. When Chinese domestic demand for these products is softer than production capacity, the surplus flows into export markets, increasing the global supply of aluminium-content products and depressing prices for competing producers elsewhere. In the current environment, robust Chinese production combined with relatively subdued domestic Chinese demand has resulted in elevated export volumes that are contributing to the global price softness affecting Indian markets.
The Dollar Effect
Aluminium is priced on the LME in US dollars. When the dollar strengthens against the Indian rupee, the rupee cost of importing aluminium or aluminium-priced secondary ingot rises even if the LME dollar price is flat or falling. Conversely, when the dollar weakens, rupee-denominated aluminium costs fall more than the LME move alone would suggest. In the current environment, a stronger dollar is applying upward pressure on the rupee cost of aluminium that partially offsets the benefit of falling LME prices for Indian buyers. The net effect on landed cost depends on the magnitude of each movement — and Indian foundries buying secondary ingot priced against LME need to track both variables, not just the headline LME number.
The Double-Edged Impact on Foundries
Falling aluminium prices are unambiguously good for foundries in terms of input costs — lower metal prices reduce the single largest variable cost in casting operations. For foundries operating on fixed-price contracts (where the selling price is set at contract award and not adjusted for metal price movements), a period of falling aluminium costs directly expands margins. For foundries on pass-through contracts (where selling prices move with metal prices), the margin impact is neutral, but cash flow improves because lower metal spend reduces working capital requirements. The complication arises when falling metal prices signal softer overall demand in manufacturing end markets — a scenario where input cost relief is offset by reduced order volumes or pricing pressure from customers who expect to share in the metal cost saving.
Secondary Ingot Pricing and the LME Relationship
Most Indian foundries buy secondary aluminium ingot rather than primary metal. Secondary ingot is priced at a discount to LME primary, with the discount reflecting the quality differential, scrap input costs, and local supply-demand conditions. When LME falls, secondary ingot prices typically follow with a short lag — secondary ingot traders adjust their buying prices for scrap and their selling prices for ingot in response to LME movements. The relationship is not perfectly linear: if domestic scrap availability is tight (as the ALEMAI Aluminium Bharat 2026 initiative highlighted), the secondary discount over LME may narrow even as LME falls, muting the benefit for foundries. Understanding this secondary market dynamic — not just tracking LME — is essential for foundry procurement managers trying to optimize metal buying in a volatile price environment.
Strategic Implications for Foundry Procurement
A period of falling or soft aluminium prices is an opportunity for foundries to lock in favourable input costs through forward buying or longer-term supply agreements with ingot vendors. It is also a moment to review pass-through contract structures with customers — ensuring that any contractual price adjustment mechanisms are clearly defined and enforceable in both directions. Foundries that have historically been passive buyers — purchasing ingot as needed at spot prices — can use a softer price environment to develop more structured procurement relationships that provide cost stability when prices eventually recover. The aluminium price cycle is a constant in the casting business; the foundries that manage it actively consistently outperform those that simply absorb whatever the market delivers.
