〔Day Digest〕Cash Copper Spread Blows Past $500/T as Miners' Output Drops 3.9% and Korea Pays $1B for Supply - Lithium Creeps Up, SDIC Unit Liquidated

0. Weekly Arc

The copper market has moved from a broad uptrend into a physical squeeze. LME cash copper's premium over the three-month contract blew past $500/t intraday, after earlier touching $478/t — the widest since the 2021 short squeeze ^[1][2]. The squeeze has two engines: tariff-driven shipments draining copper into the US, and a Jefferies-reported 3.9% y/y drop in Q2 output from miners covering ~55% of global supply ^[2][3]. Yet the same packet shows the bull case is not unanimous: copper is up roughly 15-16% YTD despite the deficit talk, and the LME inventory overhang is a mere ~200,000 tonnes, meaning a tariff resolution could release stock back ^[2][3]. The falsification test: if LME warehouse stocks stop falling after US tariff policy becomes clear, the $500+ spread is a logistics distortion, not a structural deficit ^[2][1].

1. Copper: The Squeeze Builds

• **[ESCALATED] Physical premium:** LME cash-to-three-month backwardation widened from a session-early $478/t to above $500/t, with supply tightness cited as the cause ^[2][1]. BNP Paribas metal analyst David Wilson attributes the earlier $478 print to continuous shipments of copper to the US ahead of Trump administration tariff decisions, which reduces available supply in other regions ^[3].
• **[NEW] Mine supply shock — Jefferies (relayed via trading desk):** Major miners covering ~55% of global mine supply cut Q2 output by 3.9% y/y, with Freeport-McMoRan, Ivanhoe Mines, Antofagasta, BHP and Newmont all hit by operational disruptions, grade declines, or execution problems ^[3]. Jefferies believes mine-supply risk is "clearly skewed to the downside" and sees a significant deficit over the next 12+ months even in a 2% global GDP scenario; the 2026 gap is estimated at 440,000 tonnes ^[3].
• **[NEW] Price action:** LME three-month copper rose 1.4% to $14,360.50, on track for an eighth straight weekly rise after seven consecutive weekly gains, and sits just below the record intraday high of $14,527.50 set in late January ^[3][2]. Chinese copper equities joined the move, with Northern Copper hitting the daily limit and multiple other producers rising ^[4].

2. Financing the Next Cycle

• **[NEW] Korea Eximbank–Glencore $1 billion loan:** The Export-Import Bank of Korea will lend $1 billion to Glencore International, a Swiss subsidiary of Glencore Plc, in exchange for copper supply to South Korean companies over the loan period ^[5][6]. The bank frames the deal around the AI boom and surging electricity demand; an official said the partnership with a company "with a unique position in global commodity markets" would secure stable supplies of key raw materials for Korea's advanced industries ^[5]. Terms and volumes were not disclosed ^[5].
• **[ONGOING] SDIC Commodities liquidation:** A Hong Kong court ordered a unit of China state-backed SDIC Commodities to be liquidated, deepening financial troubles for the metals trader as Beijing increases scrutiny of the sector ^[7].
• **[NEW] Silver India arbitrage:** Silver shipments into India are picking up despite administrative red tape as traders seek to capture premiums after a new licensing regime disrupted imports ^[8].

3. Lithium, Gold and the Rest of the Complex

• **[NEW] Lithium carbonate spot:** MMLC battery-grade lithium carbonate (morning auction) rose 1,000 yuan/t versus the prior day to a mid-price of 153,950 yuan/t, according to Mysteel ^[9].
• **[ONGOING] GFEX warehouse receipts:** Lithium carbonate futures receipts rose 591 lots to 36,689; polysilicon receipts rose 70 lots to 22,310; industrial silicon receipts were unchanged at 33,223 ^[10]. The lithium stock build is net positive for delivered metal, but the 591-lot increase is modest and does not by itself signal a renewed surplus ^[10].
• **[NEW] Gold equities, not bullion:** Hong Kong-listed gold miners rallied, with Zijin Gold International +6%, China Gold International +5.4%, Lingbao Gold and Shandong Gold +4% or better, and Zhaojin Mining and China Silver Group +3% or better ^[11]. The packet contains no physical gold price, so treat this as an equity-led move ^[11].

4. Risks and Source Quality

• The central contradiction is structural versus logistical. Jefferies says global supply risk is skewed lower and sees a 440,000-tonne 2026 gap; the LME cash premium says the market can't wait ^[3][1]. But LME inventory at just over 200,000 tonnes is the lowest since February, so any reversal of US-bound flows could quickly rebuild stocks and flatten the backwardation ^[2]. The event that would falsify the structural-deficit thesis is a tariff outcome that stops the US arbitrage and allows LME stocks to build ^[3][2].
• Sourcing caveats: the Jefferies output and deficit figures come through a trading-desk relay rather than a directly attached research report ^[3]; the $478/t spread is a Bloomberg-sourced level via Wall Street CN, while the >$500/t is a Cailian Press flash ^[2][1]. The exact spread should be read as a range that moved during the session ^[1][2].
• Scope note: the packet also contains a 64.1% jump in Shanghai ship exports, but that is not a metals price driver and is excluded from this digest ^[12].
