Report Information - Report Title: Zinc Industry Weekly Report - Report Date: December 5, 2025 - Report Author: Xu Liang (Z0002220) - Reviewer: Tang Yun (Z0002422) Report Industry Investment Rating - Not mentioned in the provided content Core Views Bullish Factors - Domestic zinc inventory has been continuously declining, with the inventory of zinc ingots in seven major regions decreasing by 0.38 million tons, indicating a tightening supply [3]. - Export orders have remained stable, and the improvement in weather has boosted terminal demand, supporting zinc prices [3]. Bearish Factors - The increase in LME zinc inventory indicates supply pressure, and weak consumption has suppressed zinc prices [3]. - Galvanizing enterprises in northern China have reduced their operating rates due to environmental protection restrictions, dragging down downstream demand [3]. Trading Advisory Views - It is recommended to pay attention to the impact of inventory changes and export data on short - term prices and operate with caution [3]. Summary by Directory Processing and Terminal Demand - Multiple data on the zinc processing industry, including the weekly market sentiment index, weekly inventory, and weekly output of galvanized coils, are presented in a seasonal chart format [5]. - Seasonal charts of net exports of galvanized sheets (strips), die - cast zinc alloys, color - coated sheets (strips), and zinc oxide are provided [6][8]. - Seasonal charts of real - estate - related data such as real - estate development investment, engineering progress, sales area, and land transaction area are shown [11][13][15]. - Seasonal charts of infrastructure fixed - asset investment (excluding rural households) in different sectors are presented [16]. Supply and Supply - side Profit - Seasonal charts of zinc concentrate monthly import volume, SMM zinc ingot monthly output, China's zinc ingot monthly production plus import volume, and zinc concentrate raw material inventory days are provided [19][22][23][25]. - Charts showing the relationship between SMM import and domestic zinc concentrate weekly processing fees, refined zinc enterprise production profit and domestic zinc concentrate weekly processing fees, and LME and SHFE zinc inventory are presented [21][22][25][26]. Futures and Spot Market Review - Charts of domestic and international zinc price trends, Shanghai zinc main contract trading volume and open interest, LME zinc closing price and US dollar index, LME zinc premium and discount, and zinc ingot basis are presented [28][29][30][32][34][37].

Group 1: Important Data - LME zinc spot premium is -$1.95 per ton. SMM Shanghai zinc spot price decreased by 80 yuan/ton to 22,570 yuan/ton, with a spot premium of -5 yuan/ton. SMM Guangdong zinc spot price decreased by 70 yuan/ton to 22,530 yuan/ton, with a spot premium of -80 yuan/ton. Tianjin zinc spot price decreased by 70 yuan/ton to 22,530 yuan/ton, with a spot premium of -45 yuan/ton [1] - On July 30, 2025, the SHFE zinc main contract opened at 22,645 yuan/ton and closed at 22,655 yuan/ton, down 80 yuan/ton from the previous trading day. The trading volume was 127,217 lots, and the open interest was 117,616 lots. The highest price was 22,725 yuan/ton, and the lowest was 22,580 yuan/ton [2] - As of July 30, 2025, the total inventory of zinc ingots in seven regions monitored by SMM was 103,700 tons, a change of 5,500 tons from the previous period. The LME zinc inventory was 112,150 tons, a change of -3,350 tons from the previous trading day [3] Group 2: Market Analysis - In the spot market, the spot premium is overall. The import ore TC is still rising. Vedanta's Q2 report shows a 7% year-on-year increase in zinc concentrate production. Domestic smelting profits remain high, and the expectation of oversupply in the second half of the year remains unchanged. Smelters' raw material inventory has increased to 29.7 days, with sufficient raw material reserves and low procurement enthusiasm for the ore end [4] - On the consumption side, the downstream operating rate shows relative resilience, and overall consumption is not bad, but it cannot offset the high growth on the supply side. Social inventory shows a trend of accumulation, and it is expected that this trend will continue in the second half of the year. At the same time, overseas inventory has been increasing continuously. A rapid increase in social inventory will suppress zinc prices [4] Group 3: Strategy - Unilateral: Cautiously bearish [5] - Arbitrage: Neutral [5]

Report Industry Investment Rating - Unilateral: Neutral [4] - Arbitrage: Neutral [4] Core View - The short - term direction of zinc price fluctuations is difficult to judge. Overseas geopolitical conflicts have changed, causing the zinc futures price to rise. The consumption side may face challenges in May, and there is a possibility of a month - on - month weakening in consumption after May. Attention should be paid to inventory changes [1][3]. Summary by Related Content Important Data - Spot market: In the Guangdong region, inventory has been continuously declining, and due to shortages of individual brands, the spot premium has slightly increased. In the East China region, the procurement enthusiasm has declined due to the replenishment of imported zinc ingots in the early stage. In the North China region, procurement is mainly for rigid demand, and the overall spot market premium and discount remain stable. In the overseas mining end, the output in the first quarter was lower than expected, but it does not change the expectation of zinc ingot surplus. Although the upside space of TC is limited, smelting still has profits at the current TC price, and the smelting enthusiasm remains, with supply pressure still existing. The inventory of imported mines in China is sufficient, and there are no conditions for a short - term TC reduction. The consumption side may face a test in May, and there is a possibility of a month - on - month weakening in consumption after May [1][3]. - Futures: On May 20, 2025, the main SHFE zinc contract opened at 22,415 yuan/ton and closed at 22,435 yuan/ton, a decrease of 30 yuan/ton from the previous trading day. The trading volume throughout the trading day was 94,706 lots, a decrease of 31,390 lots from the previous trading day. The position throughout the trading day was 76,630 lots, a decrease of 8,930 lots from the previous trading day. The intraday price fluctuated, with a maximum of 22,490 yuan/ton and a minimum of 22,360 yuan/ton [1]. - Inventory: As of May 19, 2025, the total inventory of SMM's seven - region zinc ingots was 83,800 tons, a decrease of 1,700 tons from the same period last week. As of May 20, 2025, the LME zinc inventory was 156,725 tons, a decrease of 4,075 tons from the previous trading day [2].
