〔Day Digest〕SHFE Copper Drops 3.51% in a Week as Record Asian Premiums Clash With Macro Selling — AI Capex Above US$700bn Preserves the Structural Case

0. Daily Arc

• **[ESCALATED] Copper:** SHFE copper's main contract closed down 1.94% at CNY104,260 on November 6 after a 3.51% weekly fall, its largest weekly loss since mid-March, and an intraday visit to a three-and-a-half-month low ^[1][2]
• **[ESCALATED] Macro mechanism:** Wang Yunfei, deputy manager of Shanjin Futures Investment Advisory Department, said the decline reflected a slightly reduced expected risk of new copper tariffs after the U.S. midterm result, a copper price that remained too high without a fresh upside catalyst, and longs taking profits while the fate of previously stockpiled U.S. copper stayed uncertain ^[1]
• **[NEW] Physical counter-signal:** Chinese social inventories refreshed their year low, smelter deliveries to warehouses remained light, inbound copper flows were difficult to increase, and spot premiums kept rising even as downstream consumption increased only limited ^[2]
• **[ONGOING] Source quality:** The AI spending figures are drawn from one SMM presentation, and the LME inventory, zinc-concentrate, recycled-lead and sulfuric-acid items are headline-only in the supplied packet, so those pieces are watchpoints rather than independently triangulated evidence ^{[3][4][5][6][7]}

1. Copper's Macro Reset

• **[NEW] Macro expectations:** Liu Chao, senior nonferrous-metals researcher at BOC International Futures Research and Consulting, said weaker macro expectations and a post-midterm reassessment of growth and stagflation scenarios were the principal drivers of the recent shift lower ^[1]
• **[ESCALATED] Positioning:** LME and COMEX fund net-long positions continued to decline as investors waited for clarity on U.S.-stockpiled copper, providing measurable evidence of the de-risking narrative ^[1]
• **[ONGOING] SMM framework:** Low Chinese inventories and persistent mine disruption underpin copper prices, while higher oil prices and rising long-end U.S. Treasury yields pressure them, leaving the medium-term setup as high-level oscillation ^[8]
• **[NEW] Cross-asset drag:** SMM linked copper weakness to a potentially tighter U.S. fiscal outlook, AI-regulation limits on global technology shares, continued liquidity concern surrounding Federal Reserve independence and the possibility that U.S. refined-copper tariffs would be shelved ^[2]

2. Physical Tightness Meets Supply Damage

• **[ONGOING] Inventory split:** LME copper stocks continued to accumulate, with 70% held in U.S. warehouses, while Chinese social inventories fell to a new year low and spot premiums stayed elevated ^[2]
• **[ESCALATED] Chile disruption:** On November 5, Chile's National Copper Company reported a blocked tailings-transport system at its Andina mine, a possible tailings leak into the Blanco River and the closure of the mine's concentrator, then lowered its 2026 guidance and confirmed 42,100 tonnes of overreported 2024-2025 output ^[2][9]
• **[ESCALATED] Weather:** Lundin Mining again cut its copper-production guidance because of severe weather in Chile ^[10]
• **[NEW] Indonesia:** LME nickel rose more than 3% on Indonesian supply concerns, and Indonesia's forestry department said it would take severe measures against a large nickel-ore trader ^[11][12]
• **[NEW] Russia–Turkey route:** Russia will export pig iron from the Arctic port of Murmansk for the first time in 30 years, rerouting cargo around Black Sea routes affected by Ukrainian attacks; the vessel is likely bound for Turkey, and the EU has banned Russian pig-iron imports since January 1 ^[13]
• **[NEW] Physical premium:** Trafigura Group was buying large volumes of copper to expand Asian sales as local supply ran low, adding to a scramble that pushed regional spot-cargo premiums to record highs ^[14]
• **[NEW] Smelter economics:** Copper-concentrate treatment charges fell to an extreme low, but the supplied excerpt does not quantify the resulting impact on smelter production ^[1]
• **[NEW] India refining:** Industry experts warned that India's lithium- and nickel-refining plans face raw-material bottlenecks, although the packet provides no scale or timing for those constraints ^[15]

3. Demand and Localization

• **[NEW] AI infrastructure:** At SMM's November 5 conference, cable and copper-foil analyst Wang Xinyang said four major North American cloud vendors would spend more than US$700bn on AI in 2026, up about 95% year over year and nearly fivefold over three years, with capital spending typically leading data-center delivery by four to six quarters ^[3]
• **[NEW] Revenue scale:** The same presentation put Nvidia's quarterly data-center revenue at US$22.6bn in 2025 Q1 and US$51.2bn in 2026 Q3, a 1.3-fold rise over six quarters, with 2027 Q2 projected at US$89bn ^[3]
• **[NEW] Downstream mix:** Conference materials said investment in ultra-high-voltage transmission, new energy, AI computing and electric vehicles continued to rise, while industrialization of aluminum substitution for copper was accelerating ^[16]
• **[NEW] Battery-material caveat:** Chinese Academy of Sciences Academician Ouyang Minggao said the recently announced solid-state battery mass-production lines were all solid-liquid hybrids and that no genuinely all-solid-state battery had reached industrialization, although the national plan targets initial scaled application by 2030 ^[17]
• **[NEW] Localization:** Chinese investors have backed more than US$16bn of mineral-processing and manufacturing projects across Africa, where the Democratic Republic of Congo, Guinea and Zimbabwe have previously introduced mineral-export bans or restrictions ^[18]
• **[NEW] Producer margin:** Hindalco's second-quarter profit rose on firmer metal prices, but elevated coal and fuel costs could erode those gains, and the company expects aluminum to remain near current levels for the next two quarters ^[19]
• **[ONGOING] Structural risk:** ANZ identified a cyclical pullback within copper's structural bull market as the main downside risk ^[20]

4. Cross-Metal Price Tape

• **[NEW] London tape:** LME copper fell 0.64%, aluminum rose 0.28%, lead fell 0.40%, zinc fell 1.96%, tin rose 2.16% and nickel rose 0.39% overnight ^[21]
• **[NEW] Shanghai tape:** SHFE copper slipped 0.05%, aluminum gained 0.43%, lead fell 0.84%, zinc fell 1.31%, tin gained 1.02% and nickel gained 0.39% ^[21]
• **[NEW] Ferrous and alumina:** Main-contract alumina rose 0.49%, cast aluminum rose 0.11%, stainless steel rose 0.32%, iron ore fell 0.44%, coking coal fell 0.25% and coke fell 0.15%, while rebar and hot-rolled coil each gained less than 0.2% ^[21]
• **[ONGOING] Earlier markers:** SMM's daily and midday reviews had lithium carbonate leading gains while Shanghai tin and copper were among the decliners, and an intraday update showed Shanghai tin falling more than 3% ^[22][23][24]
• **[NEW] Precious metals:** COMEX gold fell 0.83% overnight but gained 4.63% for the week, COMEX silver fell 0.78% overnight but gained 5.46% for the week, Shanghai gold fell 0.53% while gaining 0.92% for the week, and Shanghai silver fell 0.41% to post a seventh weekly decline and finish the week down 0.06% ^[21]

5. Decision Points and Falsifiers

• **[ONGOING] Physical test:** Elevated Chinese spot premiums and annual-low social inventories must be weighed against continued LME accumulation and the concentration of 70% of LME stocks in U.S. warehouses ^[2]
• **[ONGOING] Supply test:** The Andina closure, Chile's National Copper Company's guidance cut, Lundin Mining's weather downgrade and Indonesia's nickel measures are the key tests for physical availability, while depressed concentrate treatment charges signal smelter-side stress ^{[1][2][10][9][12]}
• **[NEW] Policy test:** A further shift toward shelving U.S. refined-copper tariffs or toward a weaker fiscal and growth setup would reinforce macro pressure, making tariff expectations and the post-midterm reassessment the relevant policy inputs ^[1][2]
• **[NEW] Demand test:** Conversion of AI capital expenditure into actual data-center delivery is the four-to-six-quarter bridge between the spending headline and copper demand ^[3]
• **[ONGOING] Falsifier:** The macro-led selloff would be undermined if high Chinese spot premiums and continued domestic destocking persist while LME stocks stop building and mine disruptions broaden ^{[14][2][10][9]}
• **[ONGOING] Bottom line:** The tape is macro-led, but the physical market has not confirmed a broad copper downcycle; confirmation would require spot premiums and Chinese social inventories to weaken while LME accumulation persists ^[20][14][2]
