LME three-month aluminium closed at $3,057 per tonne on November 5, 2026, while LME warehouse stocks fell to approximately 229,000 tonnes — a level that SMM characterises as near a 20-year low. Simultaneously, global aluminium inventories measured in days of consumption fell to 44 days, the lowest level in recent years according to Kedia Advisory analysis published November 6. The convergence of price recovery and inventory tightness is not coincidental: it reflects the same supply-demand balance working through two different metrics simultaneously. After several months in which the aluminium market was characterised by recovering ex-China supply (Middle East restarts, Brazil Alumar restart, Vietnam Dak Nong commissioning) competing with softening Chinese downstream demand, the November picture shows that inventory drawdowns have been sharper than anticipated — leaving the global market with less buffer stock than the supply recovery narrative had implied. For Indian aluminium casting foundries that buy secondary alloy priced off the LME, this price and inventory picture has direct implications for input cost planning in the final weeks of 2026 and into Q1 2027.
The Inventory Picture: Why 229,000 Tonnes Matters
LME aluminium warehouse stocks serve as the market's visible buffer — the inventory that traders, consumers, and analysts can observe and trade against. When LME stocks fall toward multi-year lows, the aluminium market loses the inventory cushion that absorbs supply disruptions and demand spikes without immediately affecting price. At 229,000 tonnes — equivalent to roughly three to four days of global aluminium production — LME stocks provide very limited buffer against any unexpected supply interruption or demand surge. The market's sensitivity to supply news increases as inventory falls: at high stock levels, a smelter outage or logistics disruption can be absorbed by drawing down warehouse metal; at low stock levels, the same disruption must be reflected in price to ration available supply. This dynamic is part of why LME aluminium prices have recovered toward $3,000/mt despite the ongoing ex-China supply recovery: the new supply coming from Middle East restarts and Vietnam is being consumed as it is produced, rather than rebuilding inventory, which means the low-inventory price support persists even as supply volumes increase.
The India Domestic Price Transmission
Indian domestic aluminium prices — set by primary producers Hindalco and Vedanta with reference to LME, plus conversion premium and import parity — typically track LME movements with a one to two week lag at the ingot level and a somewhat longer lag at the secondary alloy (ADC12, LM25) level, where secondary alloy prices incorporate both primary aluminium input cost and scrap premiums. The LME recovery from sub-$2,900/mt levels in October to $3,057/mt in early November represents a move of approximately $150/mt — which at current dollar-rupee rates of approximately ₹84/$ translates to approximately ₹12,600 per tonne increase in primary aluminium input cost. For a Kolhapur foundry buying LM25 or ADC12 ingot, the secondary alloy price will reflect a portion of this primary price increase — typically 70–85% of the primary price movement passes through to secondary alloy prices within four to six weeks, depending on scrap market conditions and secondary producer margins. A foundry buying 10 tonnes of alloy per month should model a potential input cost increase of ₹85,000–1,07,000 per month if the LME recovery is sustained — a material change to operating economics that warrants attention in pricing conversations with customers.
What the Demand Side Is Saying
The inventory tightness is occurring against a demand backdrop that is mixed rather than uniformly strong. China's aluminium processing PMI fell to 48.9% in October — below the 50% expansion threshold — indicating that Chinese downstream aluminium demand is in contraction as the post-peak-season slowdown takes hold and construction-linked consumption remains structurally depressed. Outside China, however, demand from automotive, aerospace, and packaging sectors has been more resilient: the global aluminium market is experiencing a split between a softening Chinese demand profile and a steadier ex-China demand base. India's domestic aluminium demand — which includes strong growth in automotive casting, electrical conductors, and packaging — is part of the ex-China demand resilience. Indian two-wheeler production running at 20+ million units annually, SUV penetration driving passenger car aluminium content higher, and the early-stage EV casting demand all contribute to a domestic demand base that is growing faster than the global average. For Indian foundries, this means their downstream customer demand is likely to remain supportive even if LME price volatility creates input cost pressure — the demand-side risk is lower than the input cost risk in the current market environment.
Procurement Posture for Q4 2026
The low-inventory, recovering-price environment entering November 2026 suggests a procurement posture for Indian foundries that is different from what was appropriate in the sub-$2,900 LME environment of October. When LME stocks are near 20-year lows and prices are recovering, the probability of a sharp further price decline is lower than the probability of price stability or further increases — because the inventory buffer that would allow price declines to be sustained (by releasing stored metal into the market) is not there. Foundries that buy alloy on a spot or monthly basis without any forward coverage are exposed to this upside price risk in full; foundries that can lock in alloy supply at current levels through short-term forward contracts or volume commitments with their alloy suppliers are reducing that exposure at a cost (the forward premium, if any) that is likely lower than the cost of absorbing a further $100–150/mt LME increase in full. The practical action for a Kolhapur foundry's commercial and procurement team is to have this conversation with its alloy supplier now — before prices move further — rather than reacting to price change notices after the fact.
