铅锌日评：沪铅或有承压，沪锌关注海外结构性风险-20251021

Report Industry Investment Rating - No industry investment rating is provided in the report. Core Viewpoints - For lead, the supply - tight pattern has improved, part of the demand was released ahead of schedule in mid - to - late September, there is a large pressure for lead ingot inventory accumulation, and prices may be under pressure. For zinc, the fundamental situation of SHFE zinc continues to be weak with strong supply and weak demand, and with macro - disturbances, prices are under pressure. There is a need to be vigilant about overseas structural risks [1]. Summary by Related Catalogs Lead Price and Market Data - SMM1 lead ingot average price was 16,925 yuan/ton, up 0.15% from the previous day; SHFE lead futures main contract closed at 17,060 yuan/ton, down 0.09% [1]. - SHFE lead basis was - 135 yuan/ton, up 40 yuan; LME 0 - 3 lead was at a discount of 41.78 dollars/ton, up 0.07 dollars [1]. - Futures active contract trading volume was 27,656 lots, down 30.24%; open interest was 38,195 lots, down 5.03% [1]. - LME inventory was 247,300 tons, unchanged; SHFE lead warrant inventory was 29,265 tons, down 8.78% [1]. - LME 3 - month lead futures closed at 1,994 dollars/ton, up 1.14%; SHFE - LME lead price ratio was 8.56, down 1.22% [1]. Industry Information - In September 2025, refined lead exports decreased by 46% month - on - month, imports decreased by 17.17% month - on - month. Starting lead - acid battery exports decreased by 4.14% month - on - month, imports increased by 74.41% month - on - month [1]. - On October 17, [LME 0 - 3 lead] was at a discount of 41.85 dollars/ton, and the open interest was 155,573 lots, an increase of 2,687 lots [1]. Fundamental Analysis - There is no expected increase in lead concentrate imports, and processing fees are likely to rise but difficult to fall, not having a substantial impact on smelter operations. Some smelters have maintenance plans, and the operation rate of primary lead fluctuates slightly. For secondary lead, smelters that had previous maintenance are gradually resuming production, increasing supply. On the demand side, the terminal market has not improved significantly, the peak - season effect has not been reflected, dealers mainly digest inventory, and manufacturers produce according to sales [1]. Trading Strategy - Temporarily wait and see [1]. Zinc Price and Market Data - SMM1 zinc ingot average price was 21,800 yuan/ton, up 0.09% from the previous day; SHFE zinc futures main contract closed at 21,855 yuan/ton, up 0.18% [1]. - SHFE zinc basis was - 55 yuan/ton, down 20 yuan; LME 0 - 3 zinc was at a premium of 230.29 dollars/ton, up 93.44 dollars [1]. - Futures active contract trading volume was 86,404 lots, down 2.57%; open interest was 65,610 lots, down 15.04% [1]. - LME inventory was 37,325 tons, unchanged; SHFE zinc warrant inventory was 66,419 tons, down 1.33% [1]. - LME 3 - month zinc futures closed at 2,976 dollars/ton, up 1.14%; SHFE - LME zinc price ratio was 7.34, down 0.94% [1]. Industry Information - In September 2025, zinc concentrate imports were 505,400 tons (physical tons), a month - on - month increase of 8.15% (38,000 physical tons) and a year - on - year increase of 24.94%. The cumulative zinc concentrate imports from January to September were 4,008,000 tons (physical tons), a cumulative year - on - year increase of 40.49% [1]. - In September 2025, refined zinc imports were 22,700 tons, a month - on - month decrease of 3,000 tons or 11.6%, and a year - on - year decrease of 57%.

Fundamental Analysis - Smelters have sufficient raw material inventories, and zinc ore processing fees continue to rise. Last week, domestic zinc concentrate processing fees fell to 3,400 yuan/metal ton, and the import zinc ore processing fee index rose to 118.75 dollars/dry ton. Affected by the low internal - external price ratio, domestic ores have an advantage, and smelters mainly purchase domestic ores. Domestic TC in October may still decline. On the supply side, smelter profits and production enthusiasm have improved, and the monthly output is expected to remain at around 600,000 tons. On the demand side, there is no significant improvement. As the SHFE - LME ratio continues to deteriorate, the zinc ingot export window is expected to open [1]. Trading Strategy - Temporarily wait and see [1].
