〔Day Digest〕Lithium Drops 3-4% as Warrant Inflows Build, Copper Loses 3-Week High on LME Deliveries — BlackRock's 'Tight Market' Call vs. the Squeeze Easing

0. Weekly Arc

The early-week lithium rebound unwound sharply: main contract 2701 fell 3.01% to 150,660 yuan/ton after touching 155,400 in the prior session ^[1][2]. Copper, which had been bid, gave up its biggest three-week loss as LME deliveries eased a "historic squeeze" ^[3]. The pivot is visible versus invisible inventory — GFEX warehouse receipts accelerated while weekly stockpiles still drew down, and the copper squeeze is finally meeting metal at the warehouse door ^[1][4][3]. Global long-end yields (German 10Y ~3.26%, US 30Y at 2007 highs, 10Y UST above 4.7%) are a parallel headwind across the complex ^[5].

1. Lithium Carbonate — Visible Inventory Builds, Price Caps

• **[NEW] Main 2701 contract fell 3.01% to 150,660 yuan/ton, open interest up 4,347 lots to 315,600**; intraday loss exceeded 4%, touching 149,120 yuan/ton ^[1][6].
• **[NEW] Battery-grade spot fell 1,850 yuan/ton to a 149,800-153,500 yuan/ton range; industrial-grade fell 1,850 to 144,800-148,500; 6% lithium concentrate fell $15 to $2,165/ton** ^[1]. Mysteel's MMLC early read was down 1,000 yuan/ton at 152,000 ^[7].
• **[ESCALATED] GFEX lithium carbonate warehouse receipts rose 1,239 lots to 38,608 lots**, extending the visibility pattern; polysilicon warrants +270 to 22,580, industrial silicon +288 to 33,511 ^[4]. Huatai notes that above 155,000 yuan/ton, trader turnover and warrant additions accelerate — the "invisible-to-visible" pressure that caps rallies ^[1].
• **[ONGOING] Weekly Mysteel inventory fell 6,320 tons to 142,700 tons** (lithium salt factories -4,150, traders -740, materials/terminals -1,480) ^[1]. Everbright's larger-sample data shows -7,196 tons to 93,908 tons ^[2]. The draw continues, but Huatai expects the downtrend to moderate and pins a 140,000-160,000 yuan range trade ^[1].
• **[ONGOING] Supply/demand still expanding**: weekly output up 181 tons to 23,152; August production guided up 7% MoM to 112,000 tons; LFP +5% MoM to 565,100 tons, NCM +5% to 93,840 tons, lithium battery output +7% to 288.9 GWh ^[2]. Demand growth is intact, but supply is catching up — and the visible-inventory data is what the tape is reacting to, not the absolute level.

2. Lithium Project — Single-Source Read

• **[NEW] Tibet Mining (Q&A on interactive platform):** Zabuye lithium carbonate capacity "remains unstable"; project is "in ramp-up phase"; the company is running process optimization and equipment matching with partners ^[8]. Single company disclosure, no third-party verification. Marginal read: another greenfield asset still not contributing stable tons.

3. Copper — Squeeze Easing, But the Tape Disagrees

• **[NEW] Copper held its biggest loss in over three weeks** as traders made "significant deliveries" to LME warehouses, easing a "historic squeeze" ^[3].
• **[NEW] Comex-LME spread narrowed to ~$250/ton from ~$410/ton prior**; LME inventory jumped 15,725 tons to 223,550, Comex up 1,358 tons to 670,280, SHFE warrants up 2,829 tons to 5,812 ^[9][10]. The inventory build is the mechanism — and it is single-source via the wire, not yet corroborated by exchange-grade breakdowns.
• **[NEW] BlackRock's Evy Hambro (head of fundamental equities thematic and sector investing) on Bloomberg Television:** "The trend is very much your friend... We are seeing a very tight market... if you've done that you've missed out" ^[11]. Direct contradiction with the price action and the LME delivery flow — flag both.
• **[NEW] Copper futures drop to cycle lows ahead of FOMC minutes** ^[12].

4. Macro Tape — Long-End Yields Doing the Work

• **[NEW] Trump stated no talks with Iran are planned or scheduled**; Iran continues hawkish military/shipping signals; Hormuz Strait security risk "suddenly elevated" — oil high-level oscillation, dollar firmer, markets briefly repricing rates ^[9][5].
• **[NEW] US July manufacturing output +0.2% MoM** — structural split continues (semis/AI/data center/defense strong; autos weak); the cycle is being read as a structural capex cycle, not a classic demand-inventory recovery ^[5].
• **[NEW] Global long-end bond selloff spreading to Europe:** German 10Y ~3.26% (2011 high), US 30Y at 2007 highs, 10Y UST holding above 4.7%; long-end supply and fiscal deficit pressure cited as common drivers; US stocks down across the board, gold/silver/copper under pressure ^[5]. This is the cross-asset backdrop the metals complex is fighting.
• **[ONGOING] China July data softens:** industrial output +4.5% YoY (down 0.8pp from June), retail sales +0.6% (down from 1.0%), real estate investment -19.2% YTD, new home sales -13.1% YTD ^[9][10]. Demand-side caution reinforced.

5. Adjacent Metals and Cross-Asset Notes

• **[ONGOING] Zijin Tianfeng aluminum weekly (Aug 17, authors Chen Jingmin / Li Wentao):** SHFE aluminum trading logic has shifted — de-stocking and premium are now "after-the-fact" validation of longs, not the catalyst. Macro read: FOMC "black-out" period, weak data has moved expectations from "no September hike" to "no hike this year"; dollar upside blocked. Foreign capital the dominant long, concentrated in the aluminum 10 contract to avoid direct confrontation with shorts on the main 09 ^[13].
• **[NEW] Indonesia plans a "minerals and strategic commodities" exchange covering palm oil, nickel and coal**, targeted launch Jan 1 next year ^[14]. Watch for nickel flow rerouting.
• **[ONGOING] Daily Everbright and Galaxy non-ferrous reports continue tracking lithium, copper, aluminum** ^[15][16]; Galaxy separately published an overseas zinc-mine Q2 earnings review ^[17].

6. What Decides Next

• **FOMC minutes and US August PMI** are the catalysts the macro desk flagged ^[12][5]. A hawkish-leaning minutes + soft PMI would extend the long-end rout and pressure metals across the board; a dovish surprise gives copper room to challenge the squeeze thesis again.
• **Lithium trigger levels:** a close above 155,000 yuan/ton with continued warrant additions confirms the bear case; below 140,000 triggers the bullish re-rating ^[1]. Watch GFEX daily receipt changes and SMM spot.
• **Copper contradiction test:** BlackRock's "very tight market" ^[11] versus the LME delivery flow ^[3] — if LME warehouse inflows continue, the squeeze is genuinely over; if inflows stall, the Hambro view wins. Source quality flag: the LME-delivery easing is a Bloomberg-wire single source ^[3]; the squeeze tightening claims from BlackRock are interview-only ^[11] — print the contradiction, not a verdict.
