〔Overnight Brief〕Aluminum Backwardation Hits $31.73/t as LME Aluminum Inventory Falls to Its Lowest Since 1990, While Shanghai Copper Slips 0.06% at 105,820 Yuan/t - Squeeze Meets Macro Pressure

0. Overnight Arc

• **[ESCALATED] Two-speed setup:** London aluminum's prompt market is exceptionally tight, while Shanghai copper is being held back by a stronger dollar, higher U.S. Treasury yields and hawkish Federal Reserve expectations ^[1][2].
• **[ONGOING] Core tension:** London cash scarcity can support a broader aluminum rally, but rising Chinese exports, dollar strength and optimism around Middle East de-escalation could cap the wider metals complex ^[1][3].
• **[NEW] Sourcing caveat:** The LME curve-through-2028 and Indonesian-deliverability details come from one Jin10 report citing foreign media, while the Lithium Americas tariff item is a Bloomberg headline and lead without figures ^[1][4].

1. London Aluminum Squeeze

• **[NEW] Closing tape:** LME aluminum rose 1.79% to $3,071.5/t; Shanghai aluminum's night session gained 1.1%, after the main daytime contract had fallen 1.6% to 22,430 yuan/t ^[5][6][3].
• **[NEW] Export counterweight:** China exported 593,900 tonnes of unwrought aluminum and aluminum products in October, while January-October volume reached 5.9145 million tonnes, up 17.8% y/y ^[3].
• **[ESCALATED] Cash premium:** LME aluminum spot traded at a $147/t premium to three-month futures at one point, the highest in more than 30 years ^[1].
• **[ESCALATED] Backwardation:** The Tom/Next spread reached $31.73/t, its highest level since 2021, as buyers competed for deliverable stocks ^[1][7].
• **[ESCALATED] Inventory concentration:** LME warehouse stocks fell to their lowest level since 1990, and warrants plus physical-contract longs held by two trading entities equaled 60% to 80% of usable warehouse inventory ^[1].
• **[ESCALATED] Bloomberg framing:** Bloomberg's “London Aluminum Market Faces Biggest Supply Squeeze in Decades” described contract-backing inventories plunging and much of the remaining stock controlled by two traders ^[8].
• **[ONGOING] Supply chain:** The Middle East conflict disrupted Gulf aluminum exports, some smelters were repairing damaged facilities, trade barriers constrained European and U.S. supply, and Indonesian new capacity lacked LME deliverability in the short term ^[1].
• **[NEW] Forward curve and exchange response:** The futures curve showed pressure extending to 2028, while the LME said it would use large-holder position-management rules to prevent the market from coming under excessive control ^[1].

2. Copper's Macro-Supply Split

• **[NEW] Shanghai close:** The SHFE copper main contract finished down 0.06% at 105,820 yuan/t ^[2].
• **[ESCALATED] Macro pressure:** U.S. October CPI rose 0.4% m/m, at or above 0.4% for a third straight month and above the 0.3% expectation; core CPI rose 0.3% m/m for a third straight month ^[2].
• **[ONGOING] Policy channel:** Federal Reserve Governor Waller said a 50bp hike the following month could be considered if inflation worsened, while the market had strong bets on a smaller December increase ^[2].
• **[ONGOING] Physical support:** Domestic refined copper was tight, lifting spot premiums and the Yangshan premium, although the import window had opened and further inventory drawdown still needed confirmation ^[2].
• **[NEW] Raw-material squeeze:** China's October 2026 copper-concentrate imports were 2.167 million tonnes, down 12.69% m/m and 11.59% y/y, while weak treatment charges and subdued by-product prices reduced smelter incentives ^[2].
• **[NEW] Contradictory supply data:** Zambia's mining minister said copper output rose 1.5% from January through September, while China's October concentrate imports fell on both monthly and annual comparisons ^[2][9].

3. Battery Minerals Move Indoors

• **[NEW] Refinery plan:** India's government approved a 28.14 billion rupee plan for four refineries, with the capital-support scheme covering 30% of construction costs ^[10].
• **[NEW] Plant design:** The plan includes two lithium refineries with minimum capacity of 30,000 tonnes each and two nickel refineries with minimum capacity of 50,000 tonnes each ^[10].
• **[NEW] Targets:** The government expects 100 billion rupees of investment and, by 2030, annual processing capacity of 60,000 tonnes of lithium and 100,000 tonnes of nickel ^[10].
• **[NEW] Import dependence:** India imported 18,200 tonnes of lithium compounds worth 111.6 billion rupees in 2025, about two-thirds from China; China controlled roughly 65% of global battery-grade lithium-chemical refining capacity, while India's domestic capacity was nearly zero ^[10].
• **[NEW] Adjacent support:** India's cabinet also approved 145 billion rupees in viability-gap grants for 92 GWh of grid-scale storage ^[10].
• **[ESCALATED] Black-mass export ban:** The Indian government changed lithium-ion battery black-mass exports from “free” to “prohibited” with immediate effect, encouraging domestic processing of lithium, cobalt, nickel and manganese and supporting electric-vehicle supply-chain ambitions ^[11].
• **[NEW] U.S. cost pressure:** Bloomberg's “US-Backed Lithium Americas Hit by Rising Costs on Trump Tariffs” said the company's Nevada mine was being hurt by Trump administration tariffs, but the supplied report excerpt contained no cost figures ^[4].

4. Corporate and Regulatory Crosscurrents

• **[ESCALATED] Chile's private-capital debate:** Bloomberg's “Chile Copper Giant's Woes Put Private Capital Taboo in Spotlight” reported that Chile Finance Minister Jorge Quiroz left the door open to private investment in state-owned Codelco, and Jin10 separately said the miner needed long-term private capital ^[12][13].
• **[NEW] Codelco-Adani exploration:** Codelco and India's Adani Group signed a memorandum of understanding to cooperate on exploration at Chile's Cobre Kaburgaala copper project ^[14].
• **[ESCALATED] Nickel deal at risk:** Kitco's “MMG to revise Anglo nickel deal remedies as deadline looms” said MMG would revise remedies to EU antitrust regulators for its $500 million bid for Anglo American's Brazilian nickel business; the European Commission was leaning toward a veto after negative third-party feedback and unconvinced remedies, according to two people close to the matter ^[15].

5. What Decides Next

• **[ONGOING] Aluminum falsifier:** The squeeze thesis weakens if LME stocks stop falling, the $31.73/t Tom/Next spread narrows, or the $147/t cash premium compresses; Marex analyst Ed Meir said repair could occur through overall price gains or spread narrowing depending on inventory, demand and macro conditions ^[1][7][3].
• **[ONGOING] Supply confirmation:** Further Gulf export disruption and continued smelter repair needs would reinforce prompt scarcity, while Indonesian capacity without LME eligibility could not relieve it in the short term ^[1].
• **[ONGOING] Copper test:** Continued refined-copper tightness and inventory drawdown would offset the macro drag, but the open import window and weak concentrate treatment charges leave the supply picture mixed ^[2].
• **[NEW] India test:** The refinery program's success depends on a stable, sufficient supply of hard-rock lithium ore, technology and downstream procurement channels ^[10].
• **[ESCALATED] Corporate tests:** MMG's remedy revision and Chile's move toward private capital are the next observable tests, alongside the European Commission's veto inclination ^[12][15][13].
