1. Report Industry Investment Rating - Not provided in the content 2. Core Views of the Report - The consumption side of zinc has slightly improved, and the operating rate has rebounded, with a neutral strength analysis [2]. - The inventory accumulation rhythm continues, and the galvanizing operating rate has slightly increased [3]. - Domestic zinc supply has increased as expected. With the increase in zinc concentrate supply, smelters and port zinc concentrate inventories are relatively abundant. However, there will be some maintenance in September, leading to a month - on - month contraction in supply. The consumption side has slightly improved, but terminal demand is relatively weak. In the short term, zinc prices may fluctuate within a narrow range, and in the medium to long term, a short - selling strategy on rallies is recommended. For internal and external strategies, SHFE zinc may be relatively weaker during the period of increased domestic supply and decreased demand, and short - term (within a quarter) positive spread positions can be held [5]. 3.

1. Report Industry Investment Rating - No relevant information provided. 2. Core Viewpoints of the Report - Last week, the main contract price of Shanghai zinc futures stopped falling and stabilized. The improvement of PMI data in Europe and the US and the dovish interpretation of Powell's speech at the Jackson Hole Central Bank Annual Meeting increased the market's expectation of a Fed rate cut in September, improving market risk appetite. Domestically, the A-share market continued to strengthen [3][10]. - Fundamentally, LME zinc inventories continued to decline, supporting the pattern of stronger overseas and weaker domestic zinc markets. Affected by concentrated arrivals, the zinc ore imports in July exceeded expectations, and refineries had sufficient raw material inventories, supporting stable production. The imports of refined zinc decreased in July as expected, and it is expected to remain at the current level. The smelting end maintained high supply, while downstream consumption did not improve significantly. After the decline in zinc prices, downstream buyers actively replenished their stocks at low prices, resulting in a slight decrease in inventories, but the sustainability remains to be seen [4][10]. - Overall, Powell's dovish stance boosted the rate - cut expectation and repaired market risk appetite. There were no new contradictions in the fundamentals. The decline in LME inventories and increased low - price purchases by domestic downstream provided support, but the high supply pressure from stable mining and smelting production suppressed zinc prices. Technically, the futures price found support near the previous low. In the short term, with the boost of macro - sentiment, zinc prices are expected to repair with a volatile and upward trend [4][11]. 3. Summary by Directory 3.1 Transaction Data | Contract | August 15 | August 22 | Change | Unit | | --- | --- | --- | --- | --- | | SHFE Zinc | 22505 | 22275 | - 230 | Yuan/ton | | LME Zinc | 2796.5 | 2805.5 | 9 | US dollars/ton | | Shanghai - London Ratio | 8.05 | 7.94 | - 0.11 | - | | SHFE Inventory | 76803 | 77838 | 1035 | Tons | | LME Inventory | 76325 | 68075 | - 8250 | Tons | | Social Inventory | 11.69 | 10.37 | - 1.32 | Ten thousand tons | | Spot Premium | - 50 | - 40 | 10 | Yuan/ton | [5] 3.2 Market Review - The decline of the main contract of Shanghai zinc futures (ZN2510) slowed down last week, and it stabilized and repaired in the second half of the week. The market was waiting for Powell's speech for rate - cut guidance, and the low - price purchases by downstream led to a slight decrease in weekly inventories, providing support. The contract finally closed at 22275 Yuan/ton, with a weekly decline of 1.02%. It rose during the Friday night session [6]. - LME zinc fluctuated narrowly in the first half of the week. The market revised its rate - cut expectation, and the US dollar stabilized and rebounded, suppressing the LME zinc price. On Friday, the rate - cut expectation recovered, and the contract closed at 2805.5 US dollars/ton, with a weekly increase of 0.32% [6]. - In the spot market, as of August 22, the mainstream transaction price of Shanghai 0 zinc was concentrated between 22220 - 22290 Yuan/ton, with a discount of 10 - 0 Yuan/ton to the 2509 contract. In different markets, the prices and discounts varied. In general, downstream low - price purchases were more frequent in the first half of the week, but with no obvious improvement in consumption, purchases decreased in the second half of the week, and traders' quotes remained stable, with the premium remaining weak [7]. - In terms of inventory, as of August 22, LME zinc inventory was 68075 tons, a weekly decrease of 8250 tons. SHFE inventory was 77838 tons, an increase of 1035 tons from the previous week. As of August 21, social inventory was 13.29 million tons, an increase of 0.37 million tons from August 14 and a decrease of 0.26 million tons from August 18. The decline in the zinc price center during the week boosted downstream purchasing enthusiasm, leading to a slight decrease in inventories in many places [8]. - Macroeconomically, the preliminary value of the US S&P Global Manufacturing PMI in August reached 53.3, the highest level since May 2022, far exceeding the expected 49.5. The service PMI slightly declined to 55.4, but the significant rebound in manufacturing pushed the composite PMI to a 9 - month high of 55.4. The preliminary value of the Eurozone PMI in August rebounded from 49.8 to 50.5, breaking above the boom - bust line for the first time since June 2022, higher than the expected 49.5. The US and the EU reached a framework for a trade agreement, with the EU promising to cancel all US industrial product tariffs and plan to purchase US energy and AI chips worth billions of dollars. The Fed's July meeting minutes showed a hawkish signal, but after Powell's speech, traders increased their bets on a Fed rate cut in September [8][9]. 3.3 Industry News - As of August 22, the average weekly domestic TC of SMM Zn50 was flat at 3900 Yuan/metal ton, and the SMM imported zinc concentrate index rose by 2.2 US dollars/dry ton to 92.5 US dollars/dry ton [12]. - According to customs data, in July, zinc concentrate imports were 501,400 tons, a month - on - month increase of 51.97% and a year - on - year increase of 33.58%. From January to July, the cumulative zinc concentrate imports were 3.0354 million tons, a cumulative year - on - year increase of 45.2%.

From January to July, the cumulative refined zinc imports were 209,900 tons, a cumulative year - on - year decrease of 12.72%. In July, galvanized sheet exports were 1.1975 million tons, a month - on - month increase of 5.86% and a year - on - year increase of 13%. In July, die - cast zinc alloy exports were 241.35 tons, a month - on - month decrease of 61.21% [12][13]. 3.4 Related Charts - The report provides multiple charts, including the price trend charts of SHFE zinc and LME zinc, the ratio of domestic and foreign markets, spot and LME premiums, inventory data of SHFE, LME, social and bonded areas, domestic and foreign zinc ore processing fees, zinc ore import profit and loss, refined zinc net imports, domestic refined zinc production, smelter profits, and downstream primary enterprise operating rates [15][16][17].

1. Report Industry Investment Rating - The investment rating for the zinc industry is weak, with a price range of 21,500 - 22,500 yuan/ton [3] 2. Core Viewpoints of the Report - The logic of marginal increase in mine supply is gradually being realized, refinery and port zinc concentrate inventories are relatively abundant, and after some refineries finish maintenance in May, the probability of resuming production is high. After the increase in zinc supply pressure, the surplus logic may become more apparent [5] - The consumption side has entered the traditional off - season, and the downstream restocking space is limited. After the easing of Sino - US tariff negotiations, there are still orders for rush export, but the intensity of some orders is not as strong as in previous rounds, and the boosting effect is limited. Terminal orders are gradually weakening, the production rhythm of downstream die - casting zinc and other sectors has slowed down, and the procurement space for spot is limited, mainly for rigid demand procurement, with weak spot trading during the week. Next week, approaching the Dragon Boat Festival, some enterprises have holiday plans, and the operating rate is expected to decline slightly [5] - The logic that the increase in zinc ore supply is transmitted to the increase in smelting supply pressure still holds. After refineries finish maintenance, production increases, while the demand side enters the off - season, and the support for prices is limited. The profit - loss ratio of holding short positions is quite considerable. In terms of term spreads, there is also convergence pressure on the spreads of near - end contracts, and lending positions can be held. For domestic and foreign zinc prices, long domestic and short foreign positions can continue to be held [5] 3.

The bonded area inventory remains stable, and the total global visible zinc inventory has declined [20][28][31] 3.3.4 Futures - The domestic open interest is at a relatively high level in the same period of history [31] 3.4 Supply 3.4.1 Zinc Concentrate - Zinc concentrate imports are at a high level, domestic zinc mine production is at a medium - low level, and the recovery rate of domestic and imported ore processing fees has slowed down. The zinc ore arrival volume is at a medium level, and refinery raw material inventory is abundant, at a high level in the same period of history [35][36] 3.4.2 Refined Zinc - Smelting profits are marginally recovering, smelting output is marginally recovering, and refinery finished product inventory is at a medium - high level in the same period of history. Refined zinc imports are at a historical medium level [37][40] 3.5 Zinc Demand 3.5.1 Downstream Processing Materials - Refined zinc consumption is basically the same as the same period last year. The downstream monthly operating rate has slightly recovered, mostly at a medium - low level in the same period of history [45][48] 3.5.2 Terminal - The real estate market is still at a low level, and the power grid shows structural increments [59] 3.6 Overseas Factors - European electricity prices, natural gas prices, and carbon prices show certain fluctuations, which have an impact on the profitability of European zinc smelters [61]

1. Report Industry Investment Rating - The industry investment rating is "Weak". Zinc is expected to fluctuate in the short - term due to weak supply and demand, and trend weakly in the medium - term [3]. 2. Core Viewpoints - With the resumption of mines and the gradual implementation of new and expanded production capacities, the subsequent processing fees still have a trend of rising steadily. Currently, smelter profits have significantly recovered, and the smelting revenue including by - products such as silver and sulfuric acid is close to 1000 yuan/ton. At the same time, smelter raw material and port ore inventories are at relatively high levels, and the smelting start - up rate has generally increased in the second quarter. However, in May, smelters in regions such as Yunnan are under maintenance and shut - down, and the output may decrease by more than 10,000 tons compared with April [7]. - Consumption is gradually transitioning to a slack stage, and the downstream replenishment space is limited. In terms of terminal consumption by sector, power towers are still relatively strong, while other sectors are relatively dull. After the previous sharp price decline, the downstream had a strong willingness to replenish raw materials, which to some extent reduced the subsequent demand space. It is expected that the apparent consumption peaked in April and will show a high - level contraction trend, putting pressure on the upper price limit [7]. - Fundamentally, it shows weak supply and demand. The supply - side production cuts and low social inventories support the near - end price. However, there is still an expectation of increased supply in the far - end, the inflection point of social inventories may come, and it will still operate weakly in the medium - and long - term, and the term spread also faces convergence pressure. For domestic and foreign zinc prices, the profit - loss ratio of domestic - foreign long - short arbitrage is appropriate, but attention should be paid to structural losses [7]. 3.
