〔Day Digest〕Copper Holds Near Record as LME Squeeze Drags On; Zinc Settles Into a 'Phased Truce' on Light August Delivery; Lithium Splits as Jianxiawo EIA Is Withdrawn — Squeeze, Truce, and a Mine That Won't Stay Decided

0. Daily Arc

Copper led the complex higher overnight on tight physical supply and a softer dollar; SHFE copper main closed the night session at 108,700 yuan/ton, +0.50% from the prior day's 107,980 ^[1]. Bloomberg tagged the move as an extension of a record-high close, with the squeeze cooling but not clearing ^[2]. Zinc found a 'phased truce' on a far lighter-than-feared LME August delivery ^[3], while lithium traded in two directions as the Jianxiawo restart narrative reversed again on an EIA withdrawal ^[4]. A-share non-ferrous joined the rebound, copper names leading with Jinchengxin at the daily limit-up and Jiangxi Copper touching the limit ^[5].

1. Copper: Squeeze Cools, Tightness Doesn't

• **[ONGOING] Bloomberg (2026-08-26):** copper extended gains after a record high close on Tuesday, with short-term supplies still tight despite an easing of last week's severe squeeze ^[2].
• **[NEW] Stock dynamics (Everbright daily):** LME copper -1,525 tons to 238,725 tons; Comex +918 tons to 676,110 tons; SHFE warrants -2,484 tons to 38,619 tons; BC copper warrants -126 tons to 8,147 tons ^[6].
• **[NEW] China spot (Huatai):** SMM 1# electrolytic copper premium 180-320 yuan/ton, average 250, up 40 yuan/ton day-on-day; port congestion dragged imports, the export window diverted domestic cargo, and inventories drew fast — Shanghai supply tightened through the session, lifting offers and improving trade ^[1]. SHFE copper 2609 intraday touched 108,550 yuan/ton before fading; back structure and persistent import loss sustained the squeeze-premium logic ^[1].
• **[ONGOING] CITIC Futures view:** a softer USD, driven by long-end US yields pushed up on AI capex and US debt expansion and partially soothed by expanded Treasury long-bond buybacks, underpins base metals broadly; supply side still supportive as smelter output dipped last week ^[7].
• **[ESCALATED] LME squeeze risk (Everbright):** Everbright flags that the LME squeeze risk cannot be ruled out, with renewed LME stock draws and rising contango preserving a 'constructive copper' tilt, though 232-tariff implementation timing is a 'high alert' volatility trigger ^[6].
• **[NEW] Macro two-way (Everbright, Huatai):** US Conference Board August consumer confidence fell to 89.4, a seven-month low; US-Iran reported to have reached consensus on ceasefire terms, including free passage through the Strait of Hormuz ^[6][1].

2. Zinc: 'Phased Truce,' Not a Clean Cure

• **[NEW] Tianfeng (Liu Xiaoyi, 2026-08-26):** the LME August contract delivery landed Wednesday, but physical delivery was only on the order of 10,000 tons, concentrated in Hong Kong, not the 2-3万吨 the market had feared; some large-holder cargoes were moved out, so the LME structural premium is not fully cleared — longs and shorts reached only a 'phased reconciliation' ^[3]. Tianfeng flags that domestic China has ample registered-brand zinc ingot, but the conversion to LME warrants is bottlenecked by delivery economics, overseas warehouse capacity, and shipping-registration lags, while long crowding is loosening and domestic social inventory has rebuilt past 270,000 tons alongside weak July property and infrastructure data ^[3].
• **[NEW] Forward read (Tianfeng):** next 1-2 weeks zinc likely rotates to the macro lead, expected to remain choppy; the probability of an August-level extreme squeeze replaying in September is low, but the structural tight setup is not eliminated — soft-squeeze and rising nearby-premium risk remain live ^[3].
• **[NEW] Huatai:** LME zinc spot premium $131.06/ton with overseas premium running strong; SHFE zinc main closed 26,070 yuan/ton, +115 on the day; SMM seven-region zinc ingot inventory 26.83万吨, -0.21万吨; LME zinc stocks 95,050 tons, -1,800 tons ^[8].

3. Lithium: Two-Way Pull, the Mine Won't Stay Decided

• **[NEW] 36Kr / Securities Times (2026-08-26):** the Yichun Ecological Environment Bureau issued a notice withdrawing the EIA public-display filing for CATL's Jianxiawo lithium mine in Yifeng-Fengxian, citing public objection to the prior website disclosure; the notice will be re-published only after the re-filing is verified as compliant ^[4]. Jianxiawo is the world's largest proven lepidolite (lithium-mica) deposit, designed at roughly 100,000 t/yr LCE at full output, ~8-10% of national output pre-shutdown; the mining permit expired on 2025-08-09 and the mine remains suspended ^[4]. The restart path is now procedurally re-locked.
• **[NEW] Mysteel:** MMLC battery-grade lithium carbonate early-session price -2,750 yuan/ton, mid 152,450 yuan/ton ^[9].
• **[NEW] SMM (Tonghuashun):** SMM battery-grade nickel sulfate average -60 yuan/ton day-on-day ^[10].
• **[NEW] GFEX warrants (Cailian Press):** lithium carbonate 43,100 lots, +1,160 day-on-day; polysilicon 23,240 lots, -10; industrial silicon 33,535 lots, flat ^[11].
• **[ESCALATED] Tianfeng (Chen Linxuan, 2026-08-26):** within-week rumors of a bumpy Jianxiawo restart pushed lithium prices up; on a case-by-case basis, if restart slips, Q4 destocking expands and price reverts to the pre-July range; if restart proceeds, price holds the August range ^[12]. Tianfeng leans toward the destocking view: registered warrants are still climbing, but the team reads this as a downstream procurement-pace issue rather than abundant spot supply, given the steeper destocking slope and falling raw-material inventory days at downstream ^[12].
• **[NEW] Sinomine Resource Group (002738.SZ, Kitco):** secured an additional 300,000 t Zimbabwe lithium-concentrate export quota; Zimbabwe introduced quotas in April after a February export halt ^[13].

4. Nickel, Lead, Aluminum

• **[NEW] Huatai nickel (2026-08-26):** SHFE nickel main 130,520→129,120, -0.79%, volume 144,873 lots (-7,742), open interest 124,972 (+4,285) ^[14]. Policy side: DSI president stated DSI will not price products, only verify transaction prices, with prices formed by the commodity exchange market mechanism; Coordinating Minister Airlangga said Indonesia will not impose export duties or windfall taxes on coal and nickel for now, with 2027 details still undecided; ESDM has begun approving some RKAB quota increases, with dozens of companies approved but volumes undisclosed ^[14]. Supply side: HPM new rules and tight sulfur keep MHP coefficients under pressure; nickel pig iron weighs on supply-recovery expectations and cautious downstream procurement; demand side: stainless steel in traditional off-season, terminal end stays weak ^[14].
• **[NEW] Huatai lead:** LME lead spot premium -$34.54/ton; SMM 1# lead -75 yuan/ton to 15,900; SHFE lead main 16,140→16,130, -35 yuan/ton; volume -11,369 lots, open interest -2,402 lots; range-bound as activity fades ^[15].
• **[NEW] Huatai aluminum:** SHFE aluminum main 23,790→23,755, -30 yuan/ton, high 23,940, low 23,695; SMM domestic electrolytic aluminum social inventory 86.0万吨, -1.5万吨; warrant inventory 262,514 tons, -1,923 tons; LME aluminum stocks 246,825 tons, -100 tons; Guinea bauxite port outflows still declining ^[16].
• **[NEW] Tin / copper-spot (Guotai Junan titles only):** copper spot premium expanding, supports price ^[17]; tin range-bound with average trading ^[18] — both single-line briefings, thin on detail.

5. What Decides Next

• **Jianxiawo procedural lock** is the binary for lithium: a clean EIA re-filing weakens the destocking narrative; any further delay deepens Q4 destocking and pulls price back toward the pre-July range ^[12][4].
• **LME copper squeeze vs. overseas arrivals:** whether last week's severe squeeze continues to ease depends on August overseas cargo landing and fresh LME inventory prints; SHFE back structure and contango depth are the read-through ^[6][1][2].
• **Macro hand-off:** USD trajectory on US long-end yields and Treasury buybacks ^[7] vs. US-Iran ceasefire headlines and the 7-month-low US consumer confidence print ^[6][1] — two-way risk into the European open; the September LME zinc squeeze-replay probability is low, but soft-squeeze and nearby-premium risk is not eliminated ^[3].
