Terminal demand improvement in the second half of the year is limited [9] Strategy - Neutral. The pulp market fundamentals have not improved significantly, and the price is expected to continue to oscillate at a low level [10]

Group 1: Tariff Impact and Market Reaction - The U.S. President Trump announced a 50% tariff on imported copper semi-finished products and high-copper derivatives starting August 1, leading to a significant drop in COMEX copper prices and closing the arbitrage space between U.S. and London copper prices [1] - The sentiment around domestic "anti-involution" policies has cooled, resulting in a general decline in commodity prices, with the characteristics of the off-season in the non-ferrous metal sector becoming more pronounced [1] Group 2: Supply and Production Dynamics - Global copper supply remains tight, with several major copper mining companies lowering their annual production guidance due to underperformance [2] - The International Copper Study Group (ICSG) reported a year-on-year increase of approximately 300,000 tons in global concentrate production for the first five months, but refined copper production is expected to increase by only 450,000 tons due to profit pressures in the smelting segment [2] - The market anticipates a tight balance or slight shortage in the global copper market from 2025 to 2028, with expected growth in global copper mine production potentially below 1% by 2025 [2] Group 3: Processing Fees and Smelting Profitability - Antofagasta reached a copper concentrate processing fee (TC/RC) of $0.0 per thousand tons and $0.0 per pound with Chinese smelting companies for mid-2025, indicating a continued tight supply of copper concentrates [3] - Despite some smelting plants operating at a loss, the overall smelting profit has improved when accounting for by-product sulfuric acid revenue [3] Group 4: Demand Trends and Seasonal Effects - The recent U.S. tariff policy does not restrict copper raw material imports, leading to a rapid disappearance of the COMEX copper premium, with U.S. copper imports exceeding last year's levels [4] - Downstream processing enterprises are cautious about high copper prices, primarily purchasing to meet immediate needs, resulting in weak market demand [5] - The operating rate of wire and cable enterprises has dropped to around 70%, with signs of slowing progress in major power grid projects [5] Group 5: Overall Market Outlook - The supply side is becoming marginally looser due to high domestic refined copper production and steady import levels, while traditional copper-consuming industries show clear signs of off-season characteristics [6] - The pricing logic for copper is shifting from macro-driven sentiment to fundamentals, with expectations of weak copper prices in the short term due to seasonal demand fatigue and pressure from the spot market [6]

Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - For pure benzene, the supply shows a slight increase with the overall supply rising due to the increase in开工率. The demand is also increasing, but the actual demand growth is slow due to low profits. There is a slight decline in port inventory this week, and the supply - demand pattern is expected to improve in August - September, but the improvement space is limited considering high hidden inventory and insufficient terminal demand [5]. - For styrene, the supply pressure remains high with new capacity coming online, but the demand from EPS and PS sectors has increased, and there is a de - stocking trend in inventory. The supply - demand surplus is expected to ease marginally in August - September, and attention should be paid to the implementation of new capacity and exports [6]. Summary by Relevant Catalogs 1. Daily Market Summary (1) Fundamental Information - Price: On August 18, the styrene main contract closed down 0.14% at 7,230 yuan/ton with a basis of 40 (+0 yuan/ton); the pure benzene main contract closed down 0.05% at 6,186 yuan/ton [4]. - Cost: On August 18, the Brent crude oil main contract closed at 62.8 (-1.2 dollars/barrel), the WTI crude oil main contract closed at 65.9 (-1.0 dollars/barrel), and the spot price of East China pure benzene was 6,095 yuan/ton (-5 yuan/ton) [4]. - Inventory: Styrene sample factory inventory was 20.9 tons (-0.3 tons), a 1.3% de - stocking; Jiangsu port inventory was 14.9 tons (-1.0 tons), a 6.42% de - stocking; pure benzene port inventory was 14.6 tons (-1.7 tons), a 10.43% de - stocking [4]. - Supply: A new styrene plant in Shandong was put into operation, and the overall supply remained stable.

Report Summary 1. Investment Rating The provided text does not mention the industry investment rating. 2. Core Viewpoints - The industry's supply - demand pattern shows continuous capacity expansion and weak demand growth, which is consistent with previous research. There are significant differences in cost and formula among paper mills. The cash cost for enterprises to produce double - offset paper that meets the delivery standard is estimated to be in the range of 3800 - 4200 yuan/ton [3][40][42]. - After the futures are listed, double - offset paper prices face potential upward and downward risks. The downward risk comes from the negative feedback between price and cost, while the upward risk is due to the market's possible over - pessimism and high short - trading congestion [4][42][43]. 3. Summary by Directory 3.1 Supply - **Product Structure**: Enterprises focused on publishing have a higher proportion of natural - white paper. Orders from the publishing industry mainly require natural - white paper, while the proportion of natural - white paper in social orders is significantly lower. The difference in product structure between the north and south markets is due to order differences [8]. - **Formula**: Different enterprises have large differences in formula. With the continuous expansion of finished - paper production capacity and the slowdown of cultural - paper demand, enterprises are increasing the use of chemimechanical pulp and reducing the use of chemical pulp. Some producers in South China can make double - offset paper without adding softwood pulp [10][12]. - **Capacity and Production**: Some production lines may switch production. The overall operating level has not decreased significantly. Some enterprises achieved full production and sales in the first half of the year, while others had an operating level of about 80% - 90% [12]. - **Raw Material Procurement**: Most enterprises mainly purchase commercial pulp externally, covering mainstream softwood and hardwood brands. Some enterprises are self - sufficient in chemimechanical pulp, while others purchase it externally. It is difficult for some domestic hardwood pulp to completely replace imported hardwood pulp [15][18]. - **Product Conversion**: Converting between natural - white and high - white paper usually only requires adding bleach [20]. 3.2 Demand - **Sales Channels**: There is significant differentiation among sample enterprises. Publishing orders are mainly direct - sold, while social orders include both distribution and direct - to - printer sales [20]. - **Seasonal Demand**: The seasonal characteristics of demand are gradually being smoothed out. The consumption peak of pulp lags behind that of double - offset paper. There may be an opportunity for the strategy of going long on pulp and short on paper after downstream enterprises complete their bidding [22]. - **Policy Impact**: The "One Textbook, One Supplementary Material" policy has different impacts on publishers of different natures, mainly affecting social book - sellers. It may reduce the double - offset paper demand of private tutoring materials by about 20% - 30% [26]. - **Sales Radius**: Paper enterprises' sales can cover a radius of 500 - 800 km [26]. 3.3 Inventory - **Raw Material Inventory**: Self - produced pulp has little inventory, while the inventory days of externally purchased commercial pulp vary among enterprises, with small and medium - sized factories having shorter inventory days [27]. - **Finished - Product Inventory**: The inventory is slightly higher than last year but generally acceptable. Most enterprises' inventory levels are within one month, and they have clear inventory red lines [27]. - **Downstream Inventory**: Enterprises supplying paper to publishers usually reserve inventory in advance, with a cycle of half a year to one year. Traders may have a certain demand for stockpiling when the price reaches around 4000 yuan [29]. 3.4 Price and Cost - **Pricing Logic**: Paper mills price their products mainly based on orders and market conditions, i.e., demand - driven pricing. High inventory levels may lead to price cuts to reduce inventory [30]. - **Cost Factors**: Formula, wood - pulp self - sufficiency rate, and the presence of self - owned power plants have a significant impact on costs. A higher proportion of chemimechanical pulp and self - owned power plants can reduce costs [31]. - **Profitability**: Most producers still make a profit, while one enterprise is near the break - even point [37]. 3.5 Market Expectations - **Paper Price Outlook**: The industry's supply - demand contradiction is prominent, and most sample participants are not optimistic about paper prices. The downward space is estimated to be around 100 - 200 yuan/ton [38]. - **Futures Attitude**: The willingness of the industry to participate in futures depends on whether their products are delivery brands. Long - side acceptance willingness is relatively weak. Industry short - side forces need to see an absolute high price to enter the market, while long - side chips may come from private book - sellers and some traders with social - order resources [39].

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Views - **Pure Benzene**: Supply increases slightly due to new oil - benzene device production, while hydro - benzene开工率 drops. Demand from phenol rises but is partly offset by the decline in adipic acid. Overall demand is flat. Inventory decreases at East China ports due to typhoon - affected arrivals. 8 - 9月 may see slight inventory reduction, but improvement is limited due to high hidden inventory and weak consumption [5]. - **Styrene**: Supply is sufficient with new device production and resumed operations. Demand is weak, with EPS开工率 dropping significantly and PS/ABS rising slightly. Port inventory doesn't increase but remains high. Mid - term supply pressure persists with new capacity planned.
