Report Summary 1. Industry Investment Rating - Unilateral: Cautiously bullish [6] - Arbitrage: Neutral [6] 2. Core View - Overseas premiums for zinc have strengthened further, and the export profit of refined zinc in China has continued to expand. The previous bearish logic for zinc prices has begun to change due to macro - favorable factors [1][5]. 3. Summary by Relevant Catalogs Important Data - **Spot**: The LME zinc spot premium is $230.29 per ton. SMM Shanghai zinc spot price increased by 70 yuan/ton to 21,940 yuan/ton, with a spot premium of - 50 yuan/ton; SMM Guangdong zinc spot price increased by 90 yuan/ton to 21,910 yuan/ton, with a spot premium of - 95 yuan/ton; Tianjin zinc spot price increased by 70 yuan/ton to 21,940 yuan/ton, with a spot premium of - 50 yuan/ton [2]. - **Futures**: On October 21, 2025, the main SHFE zinc contract opened at 21,915 yuan/ton and closed at 21,970 yuan/ton, up 85 yuan/ton from the previous trading day. The trading volume was 108,521 lots, and the open interest was 130,442 lots. The highest price was 22,045 yuan/ton, and the lowest was 21,875 yuan/ton [3]. - **Inventory**: As of October 21, 2025, the total inventory of zinc ingots in seven regions monitored by SMM was 165,300 tons, a change of 2,500 tons from the previous period. The LME zinc inventory was 37,275 tons, a change of - 50 tons from the previous trading day [4]. Market Analysis - Overseas premiums have strengthened, and the export profit of refined zinc in China has expanded. Domestic smelters are still actively purchasing domestic zinc ores, leading to a decline in domestic TC. Although imported ores are still expensive due to the domestic - foreign zinc price ratio, their processing fees may also be adjusted downward. The domestic market remains in surplus, but with the opening of the export window, the accumulation of social inventory is expected to be less than expected. The comprehensive smelting profit has narrowed, and if this situation persists or the sulfuric acid price drops, smelting enthusiasm may be dampened, and domestic supply pressure is expected to ease [5].

Group 1: Report Investment Rating - Unilateral: Cautiously bullish; Arbitrage: Neutral [5] Group 2: Core View - Zinc prices have fallen, and there is restocking in the spot market, but social inventories are increasing and may soon exceed the five - year average. The supply pressure is prominent, and the domestic inventory build - up is expected to continue even during the peak consumption season. Zinc prices may be under pressure if the peak - season consumption expectation fails, and may show a relatively weak trend compared to other non - ferrous metals, but the impact of overseas inventories should be noted [4] Group 3: Key Data Summary Spot - LME zinc spot premium is $59.11 per ton. SMM Shanghai zinc spot price is 22,140 yuan per ton, up 310 yuan from the previous trading day, with a spot premium of - 35 yuan per ton.

LME zinc inventory is 38,250 tons, with no change from the previous trading day [3] Group 4: Market Analysis - Zinc prices have dropped, and there is restocking in the spot market, but social inventories are increasing. The cost of domestic and imported zinc concentrates (TC) is rising, and smelting profits are increasing, leading to high smelting enthusiasm. The supply is expected to increase, and the pressure on the supply side is prominent. Even during the peak consumption season, domestic inventory build - up is expected, and the current inventory build - up is accelerating. If the peak - season consumption expectation fails, zinc prices will face greater pressure [4] Group 5: Strategy - Unilateral: Cautiously bullish; Arbitrage: Neutral [5]

Report Industry Investment Rating - The rating for both unilateral and arbitrage strategies is neutral [6] Core Viewpoints - Overseas zinc inventory reduction trend remains unchanged; domestic supply pressure persists, and long - term inventory accumulation is expected. However, overseas factors support zinc prices, and attention should be paid to post - balance changes [1][5] Summary by Directory Important Data - **Spot**: LME zinc spot premium is $39.84 per ton. SMM Shanghai zinc spot price dropped by 320 yuan/ton to 21,630 yuan/ton, with a spot premium of - 25 yuan/ton.

LME zinc inventory was 41,950 tons, a decrease of 825 tons from the previous trading day [4] Market Analysis - During the long holiday, downstream开工率 decreased. Before the holiday, with the decline of absolute prices, downstream actively purchased, and the spot discount was repaired, especially in Guangdong. The supply pressure in China remains. The TC of domestic zinc mines in October continued to decline, while the TC of imported zinc mines was as high as $140 per ton. The smelting profit of the industry was maintained, and the short - term replenishment behavior could not change the long - term inventory accumulation expectation. Overseas inventory problems remained unresolved, the export window was not opened, and the hawkish attitude overseas supported the zinc price [5] Strategy - **Unilateral**: Neutral [6] - **Arbitrage**: Neutral [6]

Report Industry Investment Rating - Unilateral: Cautiously bearish [4] - Arbitrage: Neutral [5] Core View - Zinc prices have declined, and there is restocking in the spot market, but social inventories are increasing and approaching the five - year average. Spot liquidity has improved, but procurement remains cautious. The TC of domestic and imported ores continues to rise, leading to higher smelting profits and sustained smelting enthusiasm. The supply is expected to increase, and the pressure on the supply side is prominent. Even during the peak consumption season, domestic inventory accumulation is expected, and if the consumption peak expectations are not met, zinc prices will face significant pressure [4].

Core Viewpoint - The zinc market is experiencing a stable supply and demand situation, with an increase in both domestic and imported zinc concentrate inventories, while consumption is expected to decline in the short term due to seasonal factors [1] Supply Side - Domestic zinc concentrate market remains stable, with the average weekly TC price at 3,800 RMB per metal ton and the imported zinc concentrate index rising to 73.75 USD per dry ton [1] - Port inventories of imported zinc concentrate increased by 107,000 tons to 440,000 tons, indicating a robust supply [1] - Despite the increase in imported TC, domestic smelting profits are high, leading smelters to prefer domestic concentrate, suggesting potential for further TC increases [1] Smelting Sector - In July, domestic smelting plants are undergoing both maintenance and resumption of operations, with refined zinc output expected to increase by approximately 12,000 tons month-on-month [1] - The recent rise in zinc concentrate processing fees has expanded smelter profits, and with sufficient domestic zinc concentrate supply, smelting activity is likely to increase [1] Consumption Trends - July and August are typically off-peak months for zinc consumption, resulting in reduced terminal orders and lower operational enthusiasm among downstream enterprises [1] - Downstream raw material inventories are at high levels, leading to poor purchasing sentiment, although policies like "old for new" may stimulate consumption [1] - Attention should be paid to consumption in infrastructure, automotive, and home appliance sectors [1] Inventory Data - As of July 17, SMM zinc ingot inventory stood at 93,500 tons, an increase of 400 tons from July 14 and 3,200 tons from July 10 [1] - LME zinc inventory on July 18 was 119,100 tons, up 13,900 tons from July 11 [1] Market Outlook - The macroeconomic environment is improving, with indications of short positions exiting the market [1] - Zinc prices may rebound due to macroeconomic and funding conditions, but medium to long-term outlook suggests ample supply from the mining sector and potential for TC increases [1] - Smelters are expected to maintain high operating rates, leading to increased refined zinc supply, while consumption is entering a seasonal decline, potentially resulting in inventory accumulation [1] Trading Strategy - A single-sided trading approach is recommended, with short-term zinc prices expected to be strong, allowing for day trading on long positions [1] - As macro sentiment fades, consider shorting based on inventory accumulation levels [1] - For arbitrage operations, a wait-and-see approach is advised [1]

Report Summary 1. Investment Rating - Unilateral: Cautiously bearish [4] - Arbitrage: Neutral [4] 2. Core View - The spot premium of zinc continues to weaken. With sufficient raw material reserves downstream, positive US macro - data, and rising commodity prices, pressure on zinc premium will continue. The supply surplus expectation remains unchanged in the second half of the year due to increasing import ore TC, rising zinc concentrate production, and high domestic smelting profits. Although downstream consumption shows some resilience, it cannot offset the high growth on the supply side, leading to a continuous inventory build - up trend [3]. 3. Key Data Summary Spot Market - LME zinc spot premium is -$8.95 per ton. SMM Shanghai zinc spot price rose by 60 yuan/ton to 22,110 yuan/ton, with the premium down 10 yuan/ton to 20 yuan/ton.

LME zinc inventory was 121,475 tons, up 125 tons from the previous day [1][2]. 4. Market Analysis - Spot market: The spot premium is weakening. Sufficient downstream raw material reserves and positive US macro - data will continue to pressure the zinc premium. - Cost side: Import ore TC is rising. Vedanta's Q2 report shows a 7% year - on - year increase in zinc concentrate production. High domestic smelting profits and sufficient raw material inventory of smelters lead to low procurement enthusiasm. - Consumption side: Downstream operating rates show resilience, but cannot offset the high growth on the supply side. Social inventory is increasing, and the inventory build - up trend is expected to continue in the second half of the year [3].

Report Investment Rating - Unilateral: Cautiously bearish. Arbitrage: Neutral [4] Core View - The absolute price of zinc has declined significantly, and the spot market premium has not improved significantly. The supply is relatively abundant, and the zinc price is weak despite the new low of the US dollar index. The supply pressure remains high, and the negative feedback of invisible inventory may occur. The deviation between the macro - positive and the fundamentals may pull the zinc price back, and attention should be paid to the change of social inventory [3] Summary by Related Content Spot and Futures Market - LME zinc spot premium is -$18.75 per ton.

The social inventory has increased slightly, and the finished product inventory of smelters and zinc alloy inventory have increased significantly. The alloy operating rate has started to decline, and the negative feedback of invisible inventory may occur [3] - The TC of the ore end has further increased, the smelting profit has expanded, and the smelting enthusiasm has been further enhanced, so the supply pressure remains [3] - After the absolute price increase, the spot market trading has become more sluggish, and the spot premium has quickly declined [3]

Report Summary 1) Report Industry Investment Rating - Unilateral: Cautiously bearish [5] - Arbitrage: Neutral [5] 2) Core View of the Report - Zinc prices face upward pressure again. Consumption shows a marginal decline, and the lack of fundamental drivers for price increases. If social inventories continue to rise, it will exert significant downward pressure on zinc prices [1][5] 3) Summary by Relevant Catalogs Important Data - **Spot**: LME zinc spot premium is -$24.65/ton.

Zinc alloy开工率 has dropped significantly, and a negative feedback of hidden inventory may occur. TC remains stable overall, and the overseas zinc ore shipment volume is increasing. Although the further upward space is limited, the strong trend remains unchanged. There are still smelting profits at the current TC price, and the smelting enthusiasm is high, so the supply pressure remains [4] Strategy - Consumption shows a marginal decline, the spot premium has dropped significantly, and zinc price increases lack fundamental drivers. If social inventories continue to increase, it will form significant downward pressure [5]
