〔Day Digest〕Lithium Carbonate Crashes 11.79% Through 110,000 Yuan on Supply-Glut Cascade and EU Hybrid-Export Curb, While LME Copper Adds 1.01% to $14,686.65 on Codelco Fatal Avalanche - Lithium Glut vs Copper Tailwind

0. Session Arc

The Asian session split industrial metals along a clear fault line. Lithium carbonate's main contract on the Guangzhou exchange staged a 10%-plus intraday crash and closed down 11.79% — the seventh straight down session — breaking below the 110,000 yuan/tonne handle for the first time since December 22, 2025 ^[1][2][3]. LME copper, by contrast, extended an earlier gain to +1.01% at $14,686.65/tonne, lifted by a fatal Codelco El Teniente avalanche and a softer rate-hike path ^[4][5][6]. The rest of the complex traded mixed: SHFE tin +1.44%, SHFE zinc +1.03%, SHFE copper +0.93%, but SHFE nickel -1.26% ^[2].

1. Lithium — Supply-Glut Cascade

• **[ESCALATED] Two-mine supply trigger:** On October 11, Jiangte Motor announced the Qiankeng lithium mine's 3 million-tonne/year safety-facility design had passed review, with theoretical LCE capacity ~15,000 tonnes/year ^[7]. On October 8, the Yichun ecological environment bureau re-posted the Jianxiawo lithium-mine environmental assessment for public notice; per Everbright Futures, the project is the world's largest single lepidolite deposit with full-output capacity ~100,000 tonnes of LCE/year ^[7]. Everbright frames the move as a "distant excess-supply narrative" finally priced in ^[7].
• **[NEW] Intraday acceleration:** the contract moved through the 110,000 yuan handle at 1:25 a.m. local and accelerated to a 105,560 yuan/tonne print en route to an 11.79% close ^[2][3][1].
• **[NEW] Demand drag — Bloomberg:** an EU agreement limiting hybrid-car exports weighed on battery-material demand prospects ^[8].
• **[ESCALATED] Equity reaction:** A-share lithium miners dropped broadly — Rongjie Co. and Shengxin Lithium Energy -5%+, Tianhua New Energy, Dazhong Mining, Aolian Electronics also -5%+, with Yahua Group, Tianqi Lithium, Yongxing Materials, Ganfeng Lithium -3%+ ^[1].
• **[ONGOING] Cycle context:** lithium carbonate is now down roughly 50% from the May high above 200,000 yuan/tonne ^[7]. A Huxiu feature on the battery-recycling industry notes "white-list" capacity is overbuilt and externally purchased LFP scrap is now "loss-making per tonne" ^[9].

2. Copper — Codelco Tailwind, Hike Bets Easing

• **[NEW] Codelco El Teniente fatal avalanche:** two subcontractor workers died Sunday during open-pit inspection; one worker was rescued ^[5]. The site had been suspended due to severe weather; prosecutors are on site ^[5]. Codelco frames copper as supply-side fragile near historical-high prices, citing "extreme weather, safety incidents, operational issues, and falling ore grades" ^[5].
• **[NEW] Rate channel:** Bloomberg cites the copper move as traders "looked to a more hopeful outlook for interest rates and gauged the impact on supply" of the Codelco incident ^[6]. A separate Jin10 relay flagged $2.8 billion of copper long-unwind on dollar strength, with physical buyers absorbing supply and speculators positioned to re-enter ^[10].

3. Inventory Cross-Currents

• **[NEW] SHFE copper post-holiday build:** SHFE copper stocks jumped 51.62% week-on-week to 58,744 tonnes — a one-month high — as post-holiday arrivals outpaced weak downstream take-up; international copper stocks on SHFE added 603 tonnes to 11,969 tonnes ^[11].
• **[NEW] LME copper drawdown:** LME copper stocks fell to 233,025 tonnes, a near two-month low, with cancelled-warrant share near 45% — deliverable supply continuing to tighten ^[11].
• **[NEW] COMEX continues to absorb global flow:** COMEX copper stocks reached 786,330 short tons, over 70% of the three-exchange visible total; the 232-tariff decision window (originally September 28) has passed without a clear ruling, leaving U.S. refined-copper tariffs as the dominant policy overhang ^[11].
• **[NEW] LME inventory moves:** aluminum -250t, tin -15t, zinc +6,000t, lead -1,575t, nickel -636t, copper -1,750t ^[12].

4. What Would Falsify It

• Everbright's three-part test: (1) the still-fast destock pace, (2) whether basis continues to firm and end-of-year African and Jiangxi supply disruptions cause a demand-supply mismatch — versus (3) the hard-to-prove-or-disprove demand expectation that "will likely cap the price" ^[7]. SMM's daily review tags the lithium move as "demand-weakness-dominated" ^[2], while Bloomberg pins the proximate demand shock to the EU hybrid-export limit ^[8].
• **Source-quality control (thin sourcing flagged):** the Codelco fatality is single-sourced via Gelonghui and should be cross-confirmed with Chilean police or regulator filings before sizing the supply impact ^[5]. The $2.8 billion long-unwind figure is a single Jin10 relay and should be quoted as such, not as a confirmed flow ^[10]. The 110,000-yuan handle break and 11.79% close are confirmed by multiple wires ^{[1][13][2][3]}.
