〔Day Digest〕GFEX Lithium Carbonate Plunges 7.41% as LME Aluminum Stock Drops to a 1990 Low and Morgan Stanley Sees First Copper-Mine Decline Since 2017 — Waller's Pause Signal Caps the Split

0. Market Arc

A split session across the complex: battery materials liquidated while industrial metals firmed on supply tightness. GFEX battery-grade lithium carbonate's main contract closed 7.41% lower at 142,500 yuan/tonne ^[1][2][3], yet SHFE weekly aluminum stock drew down 26,796 tonnes ^[4] and LME three-month aluminum touched 3,328.50 USD/tonne — the highest since August 12 ^[5]. Fed Governor Waller's pause-leaning comments trimmed September hike odds in interest-rate futures from ~66% to ~50%, with the "hold" camp leading 6-5 ^[6][7]. Net: a supply-led base-metals bid against a battery-materials selloff, capped by a softer-dollar tailwind.

1. Lithium and Battery Materials

• **[NEW] GFEX lithium carbonate main contract -7.41%** to 142,500 yuan/tonne after an intraday 6% drop to 144,100 yuan/tonne minutes earlier ^[1][8][3]. MMLC battery-grade spot fell 1,900 yuan/tonne to a 152,200 yuan/tonne mid ^[9]. Cobalt's earlier rally is fading as Democratic Republic of Congo (DRC) exports rise under a strict new export regime ^[10].
• **[NEW] Lithium-producer H1 results, divergent:** 13 A-share listed miners and lithium-salt producers reported sharply divergent earnings — some doubled, others stayed in the red — driven by differences in technology route and resource ownership ^[11]. Names include Tianqi Lithium, Ganfeng Lithium, Yongxing Materials, Yahua Group, Salt Lake Co. and Zangge Mining ^[11].
• **[ESCALATED] Sodium-ion commercialization:** CATL plans sodium-ion mass production by end-2026; BYD is also moving in, with industry framing sodium as a cheaper, safer alternative to lithium ^[12]. Ministry of Industry and Information Technology (MIIT) Vice Minister Xiong Jijun pledged support for breakthroughs in all-solid-state, sodium-ion and lithium-metal batteries at the 2026 World Power Battery Conference in Yibin ^[13].
• **[ONGOING] GFEX warrants:** lithium carbonate 47,198 lots (+300 d/d), polysilicon 24,330 (flat), industrial silicon 33,494 (-24 d/d) ^[14].

2. Base Metals — Supply Side

• **[NEW] Copper: 2017-era supply warning.** H1 global copper-mine output fell 1.1% on ICSG data, with Codelco and Freeport-McMoRan posting double-digit declines; Morgan Stanley shifted its 2026 global copper-mine output view from expected growth to roughly flat or slightly negative — the first annual decline since 2017 if it prints ^[15]. SHFE weekly copper stock fell 9,428 tonnes ^[4]. SHFE copper closed +0.22% at 108,780 yuan on the dovish read, with the COMEX-LME spread narrowing as U.S. tariff implementation remains the swing factor; U.S. July refined-copper imports hit a record 225,094 tonnes ^[6].
• **[NEW] Aluminum: 3-week high, multi-decade stock low.** LME three-month aluminum settled +28 USD or +0.85% at 3,311.5 USD/tonne, intraday peak 3,328.50 USD/tonne since August 12 ^[5]. LME aluminum stock at 245,975 tonnes is the lowest since 1990, and SHFE aluminum has fallen 11 straight weeks, from a six-year high of 528,885 tonnes on June 12 to 391,498 tonnes ^[5]. ING commodities strategist Ewa Manthey cited physical tightness and expected seasonal Chinese demand ^[5]. SHFE weekly stock change: -26,796 tonnes ^[4].
• **[NEW] Vale Base Metals IPO shelved.** Brazil's Vale SA dropped IPO plans for its critical-minerals unit amid domestic political pushback over control of strategic mining assets; the move ends preparations including arranging a banking syndicate and pre-marketing meetings ^[16][17].
• **[ONGOING] LME daily flow:** copper -475 t, zinc +1,675 t, lead -4,850 t, aluminum -1,450 t, tin +25 t, nickel flat ^[18]. SHFE weekly: zinc -5,008 t, lead +697 t, nickel -728 t, tin +118 t, rubber -318 t ^[4]. Peru June exports: copper 174,800 t, tin 1,900 t, gold 627,800 oz, refined silver 400,000 oz, lead 153,600 t, zinc 68,800 t ^[19].

3. Policy and Cross-Asset Cross-Currents

• **[NEW] Fed Governor Waller, pause-leaning.** Said he leans toward holding rates in September if the next inflation print confirms easing; September hike odds in interest-rate futures slid from ~66% to ~50%, with the "hold" camp leading 6-5 ^[6][7]. SHFE copper gained on the read; overseas tech strength also lent some support to "compute metals" including tin, with SHFE tin settling +0.28% at 416,460 yuan ^[6][7].
• **[NEW] Anti-"involution" framework.** State Administration for Market Regulation (SAMR) Chief Engineer Liu Min said preventing cutthroat competition has been folded into the comprehensive rectification framework, signaled at the 2026 World Power Battery Conference ^[2].
• **[NEW] GFEX industrial silicon delivery zones.** Inner Mongolia and Gansu added as delivery regions for the industrial silicon contract; designated warehouses now being recruited, per the Guangzhou Futures Exchange ^[20].

4. What Would Falsify the Reads

• The aluminum supply-tightness thesis breaks if LME aluminum stock reverses off the 1990 low and SHFE aluminum breaks its 11-week downtrend ^[5].
• The 2017-style copper squeeze requires H2 production to disappoint again; a single H1 miss is not a trend yet ^[15].
• Lithium is being liquidated, not reset, until MMLC spot stabilizes; today's 1,900-yuan drop to 152,200 yuan is a single print ^[9]. Sodium-ion substitution risk is a slow-burn structural offset, not a near-term catalyst ^[12][13].
• Friday's U.S. nonfarm payrolls (consensus +56k per the ING note) and DRC cobalt-export data are the near-term catalysts ^[5][10]. Source quality: the Vale IPO and DRC cobalt stories are single-source today ^[16][17][10]; GFEX intraday prints are flash-feed ^[1][8].
