Core Viewpoints - Grasberg's unexpected copper production cut will change the global copper supply pattern in the next 12 - 15 months, and the mid - term allocation value of copper is still optimistic, with consideration of long - term mid - term orders or selling put options below 78,000 [1] - The short - term fundamentals of aluminum are acceptable, and one can hold at low prices in a low - inventory pattern and pay attention to far - month inter - month and domestic - foreign reverse arbitrage [1] - Zinc prices are oscillating this week. The short - term unilateral trend is weakly oscillating, and it is recommended to wait and see; for domestic - foreign arbitrage, partial profit - taking can be made for domestic - foreign positive arbitrage [2] - The fundamentals of nickel and stainless steel remain weak. The short - term macro aspect follows the anti - involution expectation, and the policy side has a certain motivation to support prices [3][4] - Lead prices are expected to oscillate weakly next week, in the range of 16,800 - 17,000 [5] - Tin prices are in a wide - range oscillation. In the short - term, it is recommended to wait and see, and one can lightly short above 275,000 yuan/ton; in the medium - to - long - term, hold near the cost line at low prices [10] - The supply and demand of industrial silicon are balanced in September and October, and in the medium - to - long - term, prices are expected to oscillate at the cycle bottom [11] - The price of lithium carbonate oscillates. With the support of the seasonal peak season and the explosion of energy - storage demand, the monthly balance after CATL's production cut turns to continuous inventory reduction, but the amplitude is average [11] Summary by Metals Copper - Freeport Indonesia's subsidiary's accident delays Grasberg's resumption of production, reducing the 2026 copper production guidance by about 35% (equivalent to about 270,000 tons of copper and about 1.04 million ounces of gold) [1] - The adjusted copper mine supply has no obvious increase this year, and there will be no increase in the mine supply next year if the Panama mine does not resume production [1] - Fund long positions are gradually increasing, but the focus of macro and bulk CTA funds is still on precious metals. The gold - copper ratio is at a low historical quantile [1] Aluminum - Supply increases slightly, and aluminum ingot imports provide an increase from January to August [1] - Downstream construction improves, and the production schedule of photovoltaic modules stabilizes. Attention should be paid to whether overseas demand stabilizes after the decline [1] - There is a slight inventory reduction in September, and a seasonal slight inventory increase is expected in October [1] Zinc - Domestic TC decreases further, and imported TC increases further. The domestic zinc ore supply is tight from the fourth quarter to the first quarter of next year, while the overseas mine supply increased unexpectedly in the second quarter [2] - In October, the smelting end recovers slightly month - on - month. Attention should be paid to the impact of sulfuric acid and silver prices on total profits [2] - Domestic social inventory oscillates, and overseas LME inventory decreases. The current pattern of strong overseas and weak domestic may further diverge, and the export window is close to opening [2] Nickel - The supply side expects a slight resumption of production by steel mills, the demand side is mainly for rigid demand, and the prices of nickel iron and chrome iron remain stable [3] - There is a slight inventory increase in Xifu, and a slight inventory reduction in warehouse receipts [3] Stainless Steel - The supply side expects a slight resumption of production by steel mills, the demand side is mainly for rigid demand, the price of nickel iron remains stable, and the price of chrome iron rises slightly [3][4] - There is inventory reduction in Xifu, and a slight inventory reduction in warehouse receipts [3][4] Lead - On the supply side, the scrap volume is weak year - on - year, the waste battery is in short supply, the recycled lead maintains low - level operation, and the TC quotation is in a chaotic decline [5] - On the demand side, the battery finished - product inventory is high, the battery construction rate increases this week, and the demand turns slightly prosperous [5] - The refined - scrap price difference is - 75, the long - term supply in Henan is tight, and the LME registered warehouse receipts decrease by 20,000 tons [5] Tin - On the supply side, the domestic smelting plants reduce production, and the supply from overseas gradually recovers. The supply side is marginally repaired [10] - On the demand side, the demand for solder is mainly rigid. The downstream restocking intention is strong when the price drops rapidly this week, and the inventory reduction is significant [10] - The domestic fundamentals are short - term in a situation of weak supply and demand. Attention should be paid to the expected changes after October and the impact of interest - rate cut expectations [10] Industrial Silicon - Xinjiang's leading enterprises resume production, and some factories in the southwest may gradually reduce production later [11] - The supply and demand are balanced in September and October, and in the medium - to - long - term, prices are expected to oscillate at the cycle bottom [11] Lithium Carbonate - The raw - material end has strong price - support intention from overseas mines and reluctant selling from traders, but salt factories have low acceptance of high - price lithium mines [11] - The pre - holiday stocking rhythm of the lithium - salt end is strong first and then weak, and the spot basis is weakly stable, with some discounts expanding by 100 - 200 yuan [11] - In the context of strong "anti - involution" commodity sentiment, the price elasticity is high after the supply - side disturbance speculation materializes, and the downward price support is strong before the disturbance materializes [11]
