〔Day Digest〕Tin Tumbles 5.28% at Midday, Lithium Carbonate Ends 3.91% Lower and Copper Inventories Build — Precious Metals Rally

0. Session Arc

• **[NEW] Asian-session split:** At midday, SHFE copper was down 1.65%, aluminum 0.63%, lead 0.60%, zinc 1.01%, tin 5.28% and nickel 1.08%; by the domestic close, tin's loss had narrowed to 2.7% and copper's to 0.99%. ^[1][2]
• **[NEW] External divergence:** At 15:04, LME copper was down 0.16% and lead 0.13%, while nickel gained 0.74% and the remaining external base metals posted mostly modest gains. ^[1]
• **[ONGOING] Precious-metals decoupling:** COMEX gold rose 2.34% and silver 3.95%, while Shanghai gold gained 2.52% and silver 3.39%; SMM paired the move with a weaker dollar. ^[1]
• **[NEW] Source quality:** The intraday and closing percentages come largely from one SMM feed at different timestamps, while the copper references use prior LME closes, so the figures are session snapshots rather than synchronized closes. ^[1][2][3][4]

1. Tin and Lithium Lead the Selloff

• **[ESCALATED] Early tin shock:** The 02:41 snapshot put SHFE tin down 5% at RMB 344,230 per tonne and LME tin down more than 2% at $46,310 per tonne; the later 02:44 snapshot put SHFE tin at RMB 342,700 per tonne. ^[5][6]
• **[ESCALATED] Partial recovery:** SHFE tin's reported loss was 5.28% at midday and narrowed to 2.7% at the SMM close. ^[1][2]
• **[NEW] Lithium weakness:** GFEX lithium carbonate warrants rose 2,018 lots to 21,555; the main continuous contract fell 3.29% at midday and 3.91% at the close. ^[7][1][2]
• **[NEW] Spot-price marker:** Mysteel's early MMLC battery-grade lithium price fell RMB 50 per tonne to a midpoint of RMB 93,600 per tonne. ^[8]
• **[ESCALATED] Supply pressure:** Guotou Futures said overseas lithium shipments from Australia and Africa continued to arrive, domestic port and trading inventories kept accumulating, sellable spot supply increased and mine-side supply pressure was becoming visible. ^[9]
• **[ESCALATED] Lithium inventory detail:** The quoted industrial-carbon spread narrowed to RMB 3,300, total inventory fell 1,000 tonnes to 51,000 tonnes, downstream inventory fell 900 tonnes to 29,000 tonnes, smelter inventory rose 200 tonnes to 7,600 tonnes, trader inventory fell 400 tonnes to 14,600 tonnes and weekly output rose 7%. ^[9]
• **[NEW] Counterweight:** CITIC Securities expects the lithium-battery industry's overall business climate to improve in 2027, with demand helped by greater battery content per vehicle in China. ^[10]

2. Inventory Builds Split the Complex

• **[NEW] LME stocks:** Copper inventory increased 2,600 tonnes, while lead fell 650 tonnes, aluminum 725 tonnes, nickel 2,262 tonnes, zinc 3,900 tonnes and tin 30 tonnes. ^[11]
• **[ONGOING] SHFE aluminum draw:** Aluminum stocks fell 10.26% in the week of October 30 to 191,018 tonnes, marking a 20th consecutive weekly decline and a level not seen for more than nine months. ^[12]
• **[ONGOING] Overseas aluminum tightness:** LME aluminum stocks reached a new low of 229,475 tonnes, more than 50% below the start of the year, while New York aluminum stocks were only 803 tonnes and historically low. ^[12]
• **[ONGOING] Delivery-market imbalance:** SMM said Russian-origin aluminum's share of LME deliverable stocks kept rising because pre-April 2024 material remained eligible even though UK and US rules barred new Russian aluminum; many traders avoided it, leaving circulating supply extremely tight. ^[12]
• **[NEW] Supply repair:** Middle East instability still left regional electrolytic aluminum production without a stable environment, but Gulf smelter restarts and continued Indonesian capacity ramp-ups point to recovering aluminum supply growth next year. ^[12]
• **[NEW] Copper build:** LME copper added 2,600 tonnes and COMEX copper added nearly 1,900 short tons, with the COMEX accumulation concentrated in eligible metal. ^[11][13]

3. Structural Supply and Policy

• **[NEW] US copper potential:** JPMorgan estimates that new projects and expansions could at least double annual US mined-copper output, adding 1.3 million tonnes a year; the potential global supply increment would rank third after Chile and Argentina. ^[14]
• **[NEW] Resolution copper:** The planned Resolution project in Arizona would account for roughly half of the named US capacity additions; Rio Tinto and BHP expect about 18 million tonnes over a 40-year mine life and up to 25% of US copper demand after full startup, but permitting and technical reviews make production before 2030 difficult. ^[14]
• **[ESCALATED] Nickel policy:** Indonesia is preparing to use RKAB work plans and budgets to control nickel output and restore prices to a healthy level. ^[15]
• **[ESCALATED] Nickel surplus:** Indonesia's Energy and Mineral Resources Minister Bahlil Lahadalia said nickel was around $15,800 per tonne amid a current oversupply of nearly 800,000 tonnes against annual global demand of about 3.5 million tonnes. ^[15]
• **[ESCALATED] Output restraint:** Bahlil Lahadalia urged producers to restrain output when the market cannot absorb supply while acknowledging opposition to controls implemented through RKAB. ^[15]
• **[NEW] Indian incentive:** India's Information Minister said the country had approved a critical-mineral incentive package worth ₹28.14 billion. ^[16]
• **[NEW] Sulfuric-acid setup:** SMM senior analyst Lin Yilin expects sulfuric-acid prices to return from large early swings to normal volatility in 2027, with a weak start, stable middle and stronger year-end; the report expects TC to remain low and sulfuric acid's contribution to profits to shrink versus the first half of 2026. ^[17]
• **[NEW] Acid-to-copper chain:** Lin identified export and quota liberalization plus second-half 2027 phosphogypsum- and pyrite-based acid projects as key variables, with faster commissioning intensifying pressure above RMB 1,000 per tonne; global sulfuric-acid prices also affect hydrometallurgical copper output and could return copper's core tension to mine supply and spot/futures trading. ^[17]

4. European Open, Risks and Falsifiers

• **[ONGOING] Copper macro overhang:** The earlier three-month LME copper benchmark was down 2.1% at $14,034 per tonne by 17:02 GMT after touching $13,883, its lowest since August 19, while investors assessed the fiscal implications of the US midterms. ^[3][18]
• **[ESCALATED] US political risk:** Bloomberg said early midterm results raised the prospect of a Democratic sweep of Congress as copper fell for a second day, while Mitsui's chief warned that geopolitical risks remain 'unpredictable rather than calming down'. ^[19][18]
• **[NEW] European-open read-through:** LME inventory changes, the prior copper close and US midterm risk form the packet's European-open setup; no synchronized live quote is supplied for the full metals complex, and the flagged French, German and euro-area services PMIs have no reported values in the packet. ^{[11][20][3][18][4]}
• **[NEW] Tin catalyst gap:** The packet records the early SHFE and LME selloff and the subsequent narrowing but identifies no specific catalyst for tin's decline. ^[5][6][1][2]
• **[NEW] Nickel paradox:** LME nickel stocks fell 2,262 tonnes even as Indonesia cited a current surplus near 800,000 tonnes and prepared output controls. ^[11][15]
• **[ONGOING] Lithium split:** Rising warrants and greater spot availability sit against CITIC Securities' expectation of stronger lithium-battery demand in 2027. ^[7][10][9]
• **[NEW] Falsifiers:** A reversal in LME and COMEX copper stockpiles would weaken the inventory-build reading, stabilization in lithium warrants and arrivals would weaken the supply-pressure case, formal Indonesian output controls would alter the nickel surplus, and continued aluminum destocking despite Gulf and Indonesian supply recovery would preserve the physical-tightness case. ^{[11][7][9][12][15][13]}
