〔Day Digest〕LME Nickel Extends Four-Day Rally Through $16,000 on Indonesian Cut Talk, Copper's $91.99/t Backwardation Meets Goldman's $15,400 Target - EGA Half-Capacity, Lithium -4.7%

0. Daily Arc

Nickel stole the session. LME three-month nickel broke $16,000/ton intraday for a fourth straight day of gains on coordinated-cut talk from Chinese producers in Indonesia ^[1][2][3]. Copper tightened on two layers: Goldman Sachs pinned a 2026 LME average target of $15,400/ton ^[4], while a large Oct/Nov spread at Hartree Partners by chief metals derivatives trader Sonny McNess pushed the October contract to a $91.99/ton premium over November - a classic backwardation tied to a possible Trump refined-copper tariff ^[5][6]. Aluminum split between an EGA half-capacity restart at Tavila ^[7] and an 18-week SHFE inventory draw ^[8]. The soft complex bled: battery-grade lithium carbonate fell to 102,050 yuan/ton ^[9] and the lithium carbonate main contract dropped 4.71% ^[10].

1. Nickel: The Indonesian Cut Bet

• **[ESCALATED]** LME nickel rose 2.7% intraday, through $16,000/ton, the fourth consecutive gain ^[1][2]. SHFE nickel closed +3.05%, session leader ^[10].
• **[NEW]** Executives from major Chinese nickel producers plan to meet this week to discuss coordinated Indonesia output cuts; an August attempt to agree on cuts failed ^[3].
• **[NEW] Gao Yin, Shuohe Asset Management analyst:** "What everyone cares about most now is the scale of cuts, the numbers circulating in the market are quite substantial" ^[2][3].
• Indonesian smelters remain under pressure from weak prices, rising costs, and tighter mining quotas limiting ore supply ^[2]. LME nickel stocks were flat on the day at the exchange level ^[11].
• Source-quality flag: the "quite substantial" cut-size number is single-source analyst rumor; treat the meeting outcome, not the headline, as the signal ^[2][3].

2. Copper: Structural Squeeze Meets Tactical Spread

• **[NEW] Goldman Sachs commodities team:** 2026 LME copper average target of $15,400/ton, ~7% above current spot, up from under $10,000 last year; gold target held at $5,400/oz by end-2027 ^[4].
• **[NEW] Sonny McNess, Hartree Partners chief metals derivatives trader:** long LME October / short November copper spread - the largest of several large October positions in recent weeks; the October contract traded at a $91.99/ton premium over November, classic supply-stress backwardation ^[5][6]. Bet hinges on a Trump refined-copper tariff announcement squeezing prompt supply.
• **[NEW] Grupo Mexico:** Q3 net income $2.0bn (+56% y/y), beat the $1.78bn consensus; revenue $6.33bn (+38% y/y), above the $5.81bn consensus ^[12]. 2026 copper guidance cut 6,000t to 1.028mt as Peruvian and Asarco ore grades decline ^[12]. Tia Maria project 49.6% complete by end-September, target first-half 2028 ^[12].
• **[ONGOING]** Copper 2026 tape: +15.8% YTD, +30%+ over 12 months; gold futures -4.11% YTD ^[13]. LME copper stocks +11,475t on the day ^[11]; COMEX copper stocks posted a slight build offset by outflows ^[14].
• **[NEW] Taylor Melvin, Ivanhoe Electric CEO:** tech infrastructure and defense are becoming important sources of incremental copper demand ^[13].
• **[NEW]** Other desks piling in: UBS rates copper its "highest-conviction" theme; BofA is also long copper and uranium ^[4].

3. Aluminum: EGA Half-Capacity and the 18-Week Draw

• **[NEW] Emirates Global Aluminium (EGA):** Abu Dhabi's Tavila smelter - 50% of cells repaired and restarted after conflict damage; full production targeted in Q1 2027; full sales recovery depends on Strait of Hormuz shipping easing ^[7].
• **[ONGOING] SHFE aluminum stocks:** 236,972t, down 11.04% w/w - 18th consecutive weekly decline, lowest in over eight months; high molten-aluminum ratio and seasonal demand cited ^[8].
• **[ONGOING] LME aluminum stocks:** 236,225t, fresh low, down over 50% YTD; the share of Russian aluminum in LME deliverable stock is rising as Indian draws continue ^[8]. LME Al stocks -100t on the day ^[11].
• **[ESCALATED] PJM power market:** Goldman notes forward prices have jumped from a 10-year band of $2-3/mmBtu to ~$10/mmBtu, a structural input-cost driver for aluminum smelters ^[4].

4. Lithium and the Soft Complex

• **[NEW] Lithium carbonate main contract:** -4.71% on the day, intraday low 95,680 yuan/ton ^[10][15].
• **[NEW] MMLC battery-grade lithium carbonate (early):** 102,050 yuan/ton, down 100 yuan/ton d/d ^[9].
• **[NEW] Polysilicon main contract:** -3.16%; industrial silicon -1.65% ^[10].
• **[NEW] Europe container shipping (Europe line) main contract:** -7.95% to 2,442 points, continuing slide; palladium -2.9% ^[10].
• **[ONGOING] SHFE tape at the close:** nickel +3.05% (session leader), tin +1.77%, stainless steel +2.02%, coke +1.22%; only SHFE lead -0.4% ^[10].

5. The Long Tail: Tungsten and What Falsifies the Squeeze

• **[NEW] China tungsten:** Target to raise the recycling rate to 45% by 2030, disclosed at the International Tungsten Industry Association meeting in Berlin in September ^[16]. Global scrap recovery rate ~30%, Europe/US near 50%, Japan ~30%, China ~20% ^[16].
• Falsification tests for the copper squeeze thesis: a no-tariff outcome, a no-cut outcome from the Chinese producer meeting this week ^[3], and continued LME/SHFE copper inventory builds beyond today's +11,475t ^[11].
• Source-quality flag: the EGA Tavila restart timeline rests on the company's own announcement ^[7]; the McNess position sizing is via Bloomberg-sourced "people familiar" and not confirmed by Hartree ^[5][6].
