〔Day Digest〕SHFE Copper Draws 9,744 t, Yet Tin Falls 5.8% — AI Demand Optimism Meets a 92,000 t 2027 Surplus

0. Daily Arc

• **[ONGOING] Domestic close:** SMM showed Shanghai aluminum as the only base-metal gainer at +0.15%; Shanghai tin led losses at 5.8%, copper fell 0.9%, nickel 0.81%, lithium carbonate 2.9%, polysilicon 3.65% and industrial silicon 0.63% ^[1].
• **[NEW] External tape:** LME tin fell 2.17%, LME copper 0.42% and LME zinc 0.41%, while LME aluminum rose 0.15% ^[1]. Bloomberg attributed the copper decline to a technology selloff and higher oil prices fueling concerns about global growth ^[2].
• **[NEW] Session trajectory:** The opening report showed Shanghai silver down more than 4%, tin nearly 4% and lithium carbonate more than 3%; SMM's close showed silver down 6.39%, tin down 5.8% and lithium carbonate down 2.9% ^[1][3]. A separate SHFE live snapshot put the main tin contract at RMB363,170/t on a 5% decline, which should be read alongside rather than substituted for the 5.8% close ^[4][1].
• **[ONGOING] Iron ore:** Singapore iron ore futures were headed for the lowest month-end close since October 2022 as ample global supply and elevated Chinese port stockpiles curbed demand ^[5].

1. Inventory and Registration

• **[NEW] SHFE weekly stocks:** Copper fell 9,744 t, aluminum 21,840 t, zinc 2,224 t, lead 776 t and tin 298 t, while nickel increased 1,041 t; natural rubber also fell 2,088 t ^[6].
• **[NEW] Guangzhou warehouse receipts:** Lithium carbonate rose 90 warehouse-receipt lots to 17,121, polysilicon fell 170 to 21,280 and industrial silicon fell 20 to 31,307 ^[7].
• **[NEW] Alumina registration:** The Shanghai Futures Exchange approved the "Dongfang Hope" alumina brand produced by Dongfang Hope (Sanmenxia) Aluminum, with 2.2 million t of registered capacity on standard-price terms ^[8].
• **[ONGOING] Data gap:** The LME inventory item contains no warehouse figures, while another alert only said UK LME copper, aluminum and nickel changes were due in ten minutes; no numerical LME inventory move can be reported from this packet ^[9][10].

2. Capacity, Approvals and Technology

• **[NEW] Iron phosphate:** Longpan Technology said its second-tier controlled subsidiary Shandong Liyuan plans about RMB 942 million for the Shandong Liyuan LP-15 project in Juancheng County, Shandong, to build 150,000 t/year of battery-grade iron phosphate capacity ^[11]. The board approved the plan, but shareholder approval is still required; stated funding sources are 2021 private-placement proceeds, Shandong Liyuan's own funds, bank loans or self-raised capital ^[11]. The purpose is to internalize iron phosphate feed, stabilize supply, lower procurement costs and support lithium iron phosphate cathode output ^[11].
• **[NEW] Lithium mine:** The Yichun Municipal Ecology and Environment Bureau issued the environmental-impact-assessment approval decision for Yichun Shidai New Energy Mining's new Jianxiawo lithium project in Jiangxi, with a designed mining recovery rate of 98%, 513.525 million t of designed ore resources, 30 million t/year of ore extraction and an 18-year service life ^[12]. The announcement period runs for seven days from publication ^[12].
• **[NEW] Solid-state chain:** Lithium sulfide producer "Sichuan All-Solid-State" completed a Series A financing of tens of millions of yuan led by Hongrong Capital and Mingshi Venture Capital, with Tianhong Investment, Xingxiang Sci-Tech Innovation and existing investor Inno Angel also participating ^[13]. Proceeds are earmarked for equipment upgrades and capacity expansion at a 100-ton-scale line, a Changsha R&D center and team building ^[13].
• **[ONGOING] Silicon balance:** Industrial silicon futures rebounded from lows and spot prices stabilized after last week's broad decline, but Southwest dry-season cuts had not yet appeared in concentrated form and reduced polysilicon procurement continued to pressure the market ^[14].
• **[ESCALATED] Lithium supply appetite:** Despite a sharp drop in lithium prices in recent weeks following a two-year slump, miners are looking beyond the decline to expand output ^[15].

3. Structural Demand and Hedging

• **[NEW] AI copper case:** At the SMM copper forum, analyst Wang Xinyang said four major North American operators' combined 2026 AI-related capital spending exceeded $700 billion, was up about 95% year over year and had cumulative three-year expansion approaching fivefold ^[16]. He said capital spending usually leads data-center deliveries by four to six quarters and cited Nvidia data-center quarterly revenue rising from $22.6 billion in 2025 Q1 to $51.2 billion in 2026 Q3, with a projection of $89 billion for 2027 Q2 ^[16].
• **[NEW] Copper counterweight:** The 25-analyst survey set the median 2027 LME spot-copper forecast at $14,012/t, up 7.3% from July but 3.8% below the then-current price ^[17]. It raised the 2026 global-surplus estimate by 12% to 125,000 t and lifted the 2027 surplus forecast from 50,000 t to 92,000 t ^[17]. Carsten Menke said the "demand narrative is stronger than demand reality": electrification provides structural support but has not created a boom ^[17].
• **[ONGOING] Zinc structure:** Professor Wang Shengmin of Kunming University of Science and Technology said galvanizing is zinc's largest application at about 64% of consumption and that China's zinc output moved from 7.152 million t in 2023 to 6.84 million t in 2024 and 7.528 million t in 2025 ^[18]. He said actual galvanizing consumption declined after 2024, while zinc oxide and die-casting alloy consumption also fell ^[18].
• **[NEW] Recycled-lead hedge:** Jinrui Futures investment-consulting head Luo Ping said recycled lead entered SHFE delivery in March 2026; recycled and primary spot prices have a 0.996 correlation, and recycled-lead spot has a 0.983 correlation with SHFE lead futures ^[19]. EV battery scrap can support a nominal 1:1 hedge after beta and basis checks, whereas automotive black-shell and white-shell batteries are less correlated and are better suited to partial trend-risk hedges ^[19].

4. Corporate Risks and Falsifiers

• **[ESCALATED] Vale:** Vale's third-quarter iron ore production fell short of estimates because of challenges at the Serra Norte mine in northern Brazil ^[20]. The market still headed toward its lowest month-end close since October 2022 because ample global supply and elevated Chinese port stockpiles curbed demand ^[5].
• **[ESCALATED] Codelco governance:** Codelco dismissed eight employees after investigations into irregularities in the recording and reporting of 2024 and 2025 production uncovered new evidence ^[21].
• **[NEW] Congo exploration:** Gates-backed KoBold Metals asked the U.S. State Department for help while awaiting UN Security Council clearance to run aerial surveys in the Democratic Republic of the Congo; the Financial Times said China was frustrating the exploration effort ^[22].
• **[ONGOING] Oil channel:** Guotai Junan Futures' nonferrous-and-precious-metals group co-head and chief analyst Ji Xianfei said the core geopolitical conflict remained unresolved, oil's apparent supply return was fragile, and high freight plus low global inventories supported oil's valuation ^[23].
• **[NEW] Falsification test:** The bearish supply case would strengthen if exchange-stock draws reverse while the announced phosphate and lithium projects move toward output; the demand-led countercase would strengthen if copper and aluminum draws persist as AI capital spending translates into data-center deliveries ^{[11][8][12][6][16]}.
