〔Day Digest〕Copper Hits $14,633.50/t on Chile Strike Risk and US Stockpiling as China Returns - Goldman Sees 2026 Lithium Peak vs. NEAR-Saudi Aramco DLE Launch

0. Weekly Arc

China's return from Golden Week set the tone - LME three-month copper climbed 1.1% to $14,633.50/t on Chile strike fears at Centinela and US pre-tariff stockpiling ^[1][2], while LME stocks drew in copper (-4,650t), lead (-1,525t), zinc (-325t), and tin (-15t) ^[3]. Lithium split: Goldman sees a 2026 peak and 8-18% oversupply from 2027 ^[4], while a Saudi DLE launch and GFEX hydroxide-futures consultation point to structural build-out ^[5][6][7]. Palladium capped the day at -6.48% ^[8].

1. Copper: Supply Premium on Three Fronts

• **[NEW] ANZ:** Chilean strike action may disrupt supply; if workers persist, Centinela's output could be hit within two weeks. ICE data showed LME 3M copper up 1.1% intraday to $14,633.50/t ^[1]. Bloomberg attributed the bid to Chinese buyers returning in a positive mood from the week-long holiday ^[2].
• **[NEW] Stockpiling thesis:** ANZ cited "earlier stockpiling of copper in the US in response to import tariffs" as compounding the shortage concern ^[1]. A separate piece framed the response mechanism as "demand destruction via price" ^[9].
• **[ONGOING] US-Chile:** The US is willing to help Chile expand smelting capacity ^[10] - a longer-dated offset to near-term strike risk, not a near-term price catalyst.
• **[NEW] Demand signal:** Defu Technology (copper foil) said its order book is full, high-end foil capacity is being lifted in an orderly manner, and stable relationships have been built with "several top-tier CCL plants" ^[11].
• **[NEW] COMEX:** Small inventory build with a single-point inflow at New Orleans ^[12] - the US-side counterpart to the stockpiling narrative; the build keeps the thesis from being a one-way squeeze.

2. Lithium: Peak This Year, or Structural Build?

• **[NEW] Goldman:** Raised 2026 China spot lithium carbonate forecast by 1% to $18,900/t (140,000 yuan); raised 2027 by 33% to $13,700/t (100,000 yuan); cut 2028 by 31% to $11,000/t (84,000 yuan). Sees ~16% supply deficit for most of 2026, balance by Q4, and 8-18% surplus in 2027-2028. Peak in 2026. Ganfeng 2026-2028 earnings revised +33%/+120%/-76%; maintained "Neutral"; target cut from HKD 46 to HKD 31 ^[4].
• **[NEW] Spot:** MMLC battery-grade lithium carbonate morning up 1,750 yuan/t d/d to a midpoint of 122,000 yuan/t, per Mysteel ^[13].
• **[NEW] NEAR-Saudi Aramco:** Field-services company NEAR signed with Saudi Aramco to launch the region's first direct lithium extraction (DLE) project; target 2,000 t/y battery-grade lithium carbonate; contract value up to ~$200 million; term up to 5 years ^[5][7].
• **[NEW] GFEX hydroxide:** Opened public consultation on lithium hydroxide futures and options; trade unit 1 t/lot, tick 20 yuan/t, daily limit 5% pre-delivery month and 7% in delivery month, max order 1,000 lots ^[6][14].
• **[NEW] GFEX carbonate intraday reversal:** Main contract hit +5% to 125,900 yuan/t in early trade per Tonghuashun ^[15] but closed -1.28% on the day per SMM ^[8] - the limit-up probe did not hold, consistent with Goldman framing a 2026 peak.

3. Base Metals and Precious Metals

• **[NEW] LME inventory (Oct 7):** copper -4,650t, lead -1,525t, zinc -325t, tin -15t; nickel and aluminum unchanged ^[3]. SHFE daily metals inventory data published via SMM dashboard ^[16][17].
• **[NEW] SHFE close:** Broadly red; only SHFE copper +0.63% ^[8]. Tin -3.05%, nickel -2.47%, aluminum -2.15%, zinc -1.49%, lead -0.71%. Iron ore -3.12%, rebar -1.77%, HRC -1.22%, stainless -1.82%. Coking coal +2.07%, coke -0.18% ^[8].
• **[NEW] Palladium collapse:** Main contract -6.48%; platinum -2.95% ^[8].
• **[ESCALATED] Holiday context (Oct 1-7):** LME base metals broadly down; only LME copper +0.32%; LME aluminum -1.42%, lead -1.07%, zinc -1.30%, nickel -1.19%, tin -0.01%; COMEX gold -1.25%, silver -1.16% ^[18].
• **[NEW] Macro week (Oct 2 week):** WTI -1.41%, ICE Brent +5.11%, NYMEX gas -5.44%; LME copper -2.50%, aluminum -5.46%; COMEX gold -3.43%, silver -6.18%; lithium carbonate -4.82%, cobalt -2.55% ^[19].
• **[NEW] Gold ETFs (WGC):** September saw $10 billion of global inflows, Q3 a record $31 billion; Europe and North America led; holdings +67t to a record 4,256t; AUM -7% m/m to $574 billion ^[18].

4. Trade, Policy, and Falsification

• **[NEW] Mexico anti-dumping sunset review:** Mexico's Economy Ministry launched the second sunset review of AD duties on Chinese aluminum cookware (TIGIE 7615.10.02) at Vasconia Brands' request; dumping period Jul 2025-Jun 2026, injury period Jul 2021-Jun 2026; existing duties stay in force during review; interested parties have 28 working days to register ^[20]. Prior reference price 10.6 USD/kg; Zhejiang Sanhe ≤5.65 USD/kg; other Chinese exporters ≤7.73 USD/kg ^[20].
• **[NEW] US critical minerals:** Industry groups urged Washington to "proceed with caution" on a critical-minerals stockpile, warning the buying programme risks driving up prices as competition for scarce materials intensifies ^[21].
• **[NEW] Demand backdrop (Golden Week, first 3 days):** NEV highway charging 2.97 million sessions (+48.41% y/y); charging volume 71.62 million kWh (+49.39% y/y); consumer-goods trade-in sales 19.63 billion yuan, of which autos 46,000 units for 7.45 billion yuan ^[22].
• **[NEW] Falsification tests:** Copper bid breaks if Centinela strike resolves without disruption, COMEX builds accelerate, or the US eases the tariff posture that drove the stockpiling leg ^[1][12]. Lithium-peak thesis breaks if Q4 does not bring balance and the 2027 surplus fails to materialise - the spot print at 122,000 yuan/t and the GFEX intraday reversal are early evidence the curve is bending ^{[4][15][8][13]}.
• **[NEW] Source quality control:** The Centinela two-week strike timeline, the GFEX hydroxide contract spec details, and the COMEX New Orleans single-point inflow are each single-source wires ^{[1][6][12][14]}; the Chilean smelter-cooperation item is a headline without mechanics ^[10].
