〔Day Digest〕Lithium Cracks 4% to 124,320 Yuan/Ton on Carbonate Rout; Nickel Drops 3% After Indonesia Halves 1.2% Ore Cost; Copper Holds Into Fed - Glencore Faces $2B Singapore Suit

0. Day Arc

[NEW] The industrial-metals board split cleanly: lithium and nickel routed, copper and aluminum steadied. Downside drivers were supply-side (Indonesia nickel-ore cut, growing LME copper stocks) and Chinese battery-metal softness; upside sat on structural scarcity (LME aluminum at record lows) and mine-side copper tightness ^[1][2][3][4]. The Wednesday Fed decision - widely expected to deliver the first hike since 2023 - sits over everything, with US 10-year yields above 5% already tightening financial conditions ^[5][6][7].

1. Lithium: Carbonate Cracks 4%

• **[NEW] GFEX lithium carbonate main contract** fell as much as 4.00% intraday to 124,320 yuan/ton ^[8]; the main contract was last down 2.95% on the close and 2.61% at midday ^[9][10]. Battery-grade carbonate spot (MMLC) slipped 2,750 yuan/ton from the prior 16:30 print to 128,600 yuan/ton ^[11]. Earlier session flow had the front-month off more than 2% at 127,020 yuan/ton ^[12].
• **[ONGOING] GFEX warehouse receipts** for lithium carbonate were 45,515 lots, down 1,649 lots day-on-day; polysilicon receipts at 24,880 (+30) and silicon at 33,440 (flat) ^[13].
• Mechanism: the inventory draw meets softer spot, while the broader morning tape was also weak (rapeseed meal, ethylene glycol, soy complex down) - a cross-commodity risk-off rather than lithium-isolated ^[14].

2. Nickel: Indonesia Eases, HPAL Floods In

• **[NEW] Indonesia cut its low-grade nickel-ore benchmark**, materially reducing the minimum payable price for 1.2% ore; the new formula, effective Friday, "nearly halves" the cost of 1.2% ore, with HPAL plants that convert low-grade ore into EV-battery chemicals the direct beneficiaries ^[1].
• **[ESCALATED] Supply pressure**: large new HPAL capacity comes online this year and next, on top of nickel already trading near its 2026 low; the policy change compounds downside risk ^[1].
• **Price action**: LME nickel fell 3.04% overnight; SHFE nickel dropped 1.64% on the close and 1.35% at midday; the LME cash-3M spread later signaled ample supply as the curve moved to a $62.53/t contango ^{[15][9][10][5]}.

3. Copper and Aluminum: Diverging Supply Pictures

• **[NEW] SHFE copper** closed up 0.76% at 107,740 yuan/ton after a soft open; the SMM SHFE close commentary still flagged a bearish bias as US 10-year yields above 5% and Fed hike expectations weighed on sentiment ^[7][9].
• **[ESCALATED] LME copper stocks** rose 4,925 tons alongside lead -1,500t, tin +100t, aluminum flat, nickel +210t, zinc +1,450t; the LME three-month/cash turned to a $62.53/t contango from a backwardation, signaling eased supply tightness ^[2][5].
• **[ONGOING] US tariff vacuum**: COMEX-LME premium hovering near $100, the US "siphon" of global copper fading as no new tariff measures emerge; COMEX inventory edges up with eligible-category inflows ^[7][16].
• **[NEW] Peru July exports**: copper 231,900 tons, tin 1,400 tons, gold 657,900 oz, refined silver 600,000 oz, lead 167,200 tons, zinc 88,300 tons ^[17].
• **[ONGOING] Structural view (SMM Africa Critical Minerals)**: Shairaz Ahmed, SMM chief market analyst, argued the global refined-copper market is not short, but supply pressure sits at the mine end and supports price ^[4].
• **[ESCALATED] LME aluminum stocks** at 243,600 tons, a fresh record low, down more than 50% year-to-date; SHFE aluminum stocks fell 4.67% week-on-week to 347,683 tons, a six-and-a-half-month low ^[3]. The LME draw is structural, not genuine tightness: deliverable warrants are heavily concentrated in Russian aluminum, with Indian and other-origin inventory near zero; buyers continue to avoid Russian metal even after the April 2024 UK/US ban grandfathered pre-existing stock ^[3].

4. Geopolitics, Legal and Conference Flow

• **[NEW] Glencore sued in Singapore** by Radiant World and Sapphire Minmetals for $2 billion; a London court has imposed a $499 million global asset freeze on the two plaintiffs at the request of a Jefferies-managed fund alleging fake iron-ore invoices and a fraud scheme ^[18]. The plaintiffs' legal teams are independent but the relationship is "close," per Sapphire's chairman ^[18].
• **[NEW] DRC cabinet minutes** show a DRC-US working group formally approved to accelerate the December 2024 strategic minerals partnership, originally due to launch in February but delayed; Economy Minister Daniel Mukoko Samba will chair ^[19].
• **[ONGOING] SMM 2026 Africa Critical Minerals Conference (Sept 15)**: Chimuka Nketani, Zambia National Development Agency investment director, pitched Zambia as Africa's 2nd-largest and the world's 9th-largest copper producer; SADC market 372m / $755bn GDP; AfCFTA 1.3bn / $3.4tn GDP ^[20]. Yu Shanchuan, deputy general manager of Jiangsu Qingfeng Engineering Group, warned that sulfuric acid has become a "strategic resource" - Middle East conflict has disrupted sulfur exports, hitting Zambia/DRC miners, with 3-4 tons of sulfuric acid needed per ton of hydromet copper ^[21].
• **[NEW] LME electronic options** to launch March 30, 2027; test environment opens October 19, 2026 ^[22].

5. What Would Falsify It

• A surprise Fed "hold" or dovish dot-plot would undercut the long-end/risk-off narrative compressing copper and lift lithium/nickel shorts simultaneously; a hawkish surprise (50bp) would accelerate the broader rout ^[5][7].
• A US copper-tariff announcement - even a delayed one - could re-tighten the COMEX-LME spread and reverse the LME copper stock build ^[7].
• Any Indonesia reversal on the ore benchmark would reopen the nickel bull case ^[1].

Source-quality control: the DRC cabinet-minutes figure is truncated in the source and excluded ^[19]; the LME aluminum structural breakdown is SMM's own analysis, not a third-party audit ^[3]; the Zambia conference pitch is a promotional investment-agency presentation, not independent data ^[20].
