Industrial Silicon Industry Report Industry Investment Rating Not mentioned in the report. Report's Core View The industrial silicon price is still under pressure due to the difficulty of significant increase in demand and the expected growth in production. However, the rise in raw material prices is beneficial to strengthen the cost support, and the concentrated short - position closing will bring a wave of price increase [3]. Summary by Relevant Directory - **Spot Price and Main Contract Basis**: On June 4, the price of East China oxygen - passing SI5530 industrial silicon was 8,150 yuan/ton, down 50 yuan/ton from the previous day; the price of East China SI4210 industrial silicon was 8,850 yuan/ton, the same as the previous day; the price of Xinjiang 99 - silicon was 7,600 yuan/ton, down 50 yuan/ton from the previous day [3]. - **Monthly Spread**: On June 4, the 2506 - 2507 spread was - 260, down 270 from the previous day; the 2507 - 2508 spread was - 10, up 5 from the previous day; the 2508 - 2509 spread was - 10, the same as the previous day [3]. - **Fundamental Data (Monthly)**: In April, the national industrial silicon output was 300,800 tons, down 41,400 tons from the previous month; Xinjiang's output was 167,500 tons, down 43,300 tons from the previous month; Yunnan's output was 13,500 tons, up 1,200 tons from the previous month; Sichuan's output was 11,300 tons, up 6,700 tons from the previous month.

Polysilicon Industry Report Industry Investment Rating Not mentioned in the report. Report's Core View In June, the polysilicon market is expected to remain in a situation of weak supply and demand. If there is no further production cut, there is a risk of inventory accumulation. However, due to the expected contraction of the supply side, if the production decreases and the supply - side pressure eases, the inventory is expected to be gradually reduced. Attention should be paid to the support in the range of 33,000 - 34,000 yuan/ton [4]. Summary by Relevant Directory - **Spot Price and Basis**: On June 4, the average price of N - type re -投料 was 36,500 yuan/ton, the same as the previous day; the average price of P - type cauliflower - like polysilicon was 30,000 yuan/ton, the same as the previous day; the average price of N - type granular silicon was 34,000 yuan/ton, the same as the previous day [4]. - **Futures Price and Monthly Spread**: On June 4, the price of PS2506 was 35,055 yuan/ton, up 895 yuan/ton from the previous day; the PS2506 - PS2507 spread was 2,935 yuan/ton, up 995 yuan/ton from the previous day; the PS2507 - PS2508 spread was 850 yuan/ton, down 70 yuan/ton from the previous day [4]. - **Fundamental Data (Weekly and Monthly)**: Weekly, the silicon wafer output was 134,000 CM, up 1,000 CM from the previous week; the polysilicon output was 21,600 tons, up 100 tons from the previous week.

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The pessimistic sentiment in the black commodities market is receding, leading to a bottom - up rebound. The glass and soda ash markets show a divergence between futures and spot prices due to cautious downstream procurement. The double - silicon market has a stabilized sentiment with alloy prices oscillating [1][3]. - Glass has a severe supply - demand contradiction with high inventory and lack of substantial production cuts. Soda ash faces continuous supply - demand surplus pressure and strong de - stocking pressure [1]. - For silicon manganese, low production due to profit issues and high inventory suppress prices, while manganese ore cost provides support. Silicon iron production is at a low level, but demand has some resilience, and short - term prices are affected by costs [3]. 3. Summary by Related Catalogs Glass and Soda Ash - **Market Analysis** - Glass: Futures rebounded significantly yesterday, but spot trading was weak with mainly rigid demand procurement and low speculative sentiment. Soda ash: Futures rose sharply following black commodities, while downstream procurement was cautious with mainly rigid demand replenishment [1]. - **Supply - Demand and Logic** - Glass: The supply - demand contradiction is severe, high inventory suppresses prices, and there is no substantial production cut. Long - term losses are needed to clear excess capacity, and later changes in production lines and raw material prices should be monitored. Soda ash: With new production projects coming online, the supply - demand surplus persists, and there is strong de - stocking pressure. Prices will be under pressure until the surplus situation eases, and attention should be paid to intermittent production line maintenance and new production [1]. - **Strategy** - Glass: Oscillating. Soda ash: Oscillating. No cross - period or cross - variety strategies are recommended [2]. Double - Silicon (Silicon Manganese and Silicon Iron) - **Market Analysis** - Silicon Manganese: Futures oscillated and rebounded with black commodities yesterday. The spot market was stable, and factories were reluctant to sell at low prices. The price in the northern and southern markets was 5400 - 5500 yuan/ton. Silicon Iron: Futures oscillated. The cash - inclusive ex - factory price of 72 - grade silicon iron in the main production areas was 5150 - 5200 yuan/ton, and the price of 75 - grade silicon iron was 5750 - 5850 yuan/ton [3]. - **Supply - Demand and Logic** - Silicon Manganese: Production is at a low level due to industry profits, iron - water production has slightly declined but remains high, and demand has some resilience. High factory inventory and registered warehouse receipts suppress prices, while low - level manganese ore port inventory has slightly increased, and falling manganese ore prices support alloy costs. Attention should be paid to the manganese ore supply side. Silicon Iron: Production has dropped to the lowest level in recent years due to enterprise losses, high iron - water maintains demand resilience, factory inventory de - stocking is weakening, downstream inventory is low, and short - term prices are affected by costs. Attention should be paid to electricity price changes and industrial policies [3]. - **Strategy** - Silicon Manganese: Oscillating. Silicon Iron: Oscillating [4].

Report Industry Investment Rating - Steel: Oscillating [6] - Iron Ore: Oscillating [6] - Scrap Steel: Oscillating [7] - Coke: Oscillating Weakly [7] - Coking Coal: Oscillating Weakly [10] - Glass: Oscillating Weakly [11] - Soda Ash: Oscillating Weakly [11] - Ferrosilicon Manganese: Oscillating [13] - Ferrosilicon: Oscillating [14] Core Viewpoints of the Report - During the Dragon Boat Festival, the macro - sentiment was weak, and the US further imposed tariffs on steel and aluminum, causing the prices of black building materials to decline. However, the actual impact of tariffs was limited, and there were rumors of Mongolia increasing resource taxes, leading to a price rebound at night. The domestic demand is seasonally weak, and the manufacturing's rush for exports is less than expected. Although some electric furnaces and blast furnaces are in the red, the overall profitability provides cost support. Low valuations drive price rebounds, but the upside is limited [1][2]. - In terms of iron elements, the overseas supply increase is lower than expected, and the annual cumulative shipment is down year - on - year. The new projects' progress is slow, and the annual increase is revised down. Steel enterprises' profitability and orders are good, and the molten iron output is expected to remain high. Before September, the inventory accumulation pressure is small, and the supply - demand contradiction is not prominent [2]. - For carbon elements, the coking coal production remains high, and the Mongolian coal port clearance is also at a high level, resulting in a loose supply. The coke production is at a high level, but coke enterprises face inventory reduction pressure, and the coking profit is shrinking. The coking coal inventory pressure upstream is increasing, and it's difficult to find price support [2]. - Regarding alloys, the arrival of South32 Australian ore at the port increases the pressure on oxidized ore spot. The ban on manganese ore exports by Gabon has no obvious impact on the domestic market. With the recovery of manganese ore shipments, the port inventory is rising, and the cost drag persists. The ferrosilicon supply increases slightly, and the downstream is eager to reduce inventory. The glass demand decline in the off - season is not obvious, and the supply - side news can cause market fluctuations. The soda ash supply surplus pattern remains unchanged [3]. Summary by Related Catalogs Iron Ore - Core Logic: The overseas supply increase is lower than expected, and the annual cumulative shipment is down year - on - year. New projects' progress is slow, and the annual increase is revised down. Steel enterprises' profitability and orders are good, and the molten iron output is expected to remain high, so the annual molten iron output is expected to be higher than last year. Before September, the inventory accumulation pressure is small, and the supply - demand contradiction is not prominent. The black sector rebounded last night, and iron ore also rose slightly [2][6]. - Outlook: The US tariff policy has limited actual negative impact on iron ore, but may cause pessimistic sentiment. Considering the uncertain policies, the tight supply - demand balance, and the fact that the price has factored in many negative factors, the room for further significant decline is limited [6]. Steel - Core Logic: The domestic policy is in a vacuum, and there are still tariff risks. The demand for the five major steel products rebounded this week, but the domestic demand outlook is weak. The molten iron output is high, and the steel production has increased. Although the supply - demand fundamentals improved this week and the inventory decreased, the falling raw material prices and pessimistic demand expectations suppress the price [6]. - Outlook: The fundamentals improved this week, but the outlook is still pessimistic, and the raw material prices are weakening. The steel price is expected to oscillate in the short term [6]. Scrap Steel - Core Logic: The post - holiday scrap steel arrival was low, and the loss during off - peak electricity hours increased. The apparent demand for rebar rebounded slightly, and the total inventory decreased slightly. The supply was tight after the holiday, and the demand from electric furnaces and blast furnaces was affected. The inventory increased slightly [7]. - Outlook: The market is pessimistic about the off - season demand, the finished product price is under pressure, and the electric furnace loss is increasing. The price is expected to oscillate weakly [7]. Coke - Core Logic: The second round of coke price cuts was implemented, and the market is pessimistic. The supply is stable, but the demand is weakening as the molten iron output declines and the off - season approaches [7][9]. - Outlook: The falling coking coal price weakens the cost support, and the demand is weakening. The price is expected to remain weak in the short term [9]. Coking Coal - Core Logic: The market trading atmosphere is weak, and coal mines face shipment pressure. The supply is still loose as the production remains high and the Mongolian coal port clearance is high. The coke production is high, but coke enterprises face inventory reduction pressure, and the coking profit is shrinking. The upstream inventory pressure is increasing [10]. - Outlook: The market is pessimistic, the supply - demand is loose, and the high inventory suppresses the price. The price is expected to remain weak [10]. Glass - Core Logic: The off - season demand decline is not obvious, and the deep - processing demand improved month - on - month but is still weak year - on - year. There was cold - repair and复产, and the supply pressure remains. The inventory decreased slightly, and the market is sensitive to supply - side news [3][11]. - Outlook: The real - world demand faces pressure in the off - season. The price is expected to oscillate weakly in the short term, and attention should be paid to the price cuts in Hubei [11]. Soda Ash - Core Logic: The supply surplus pattern remains unchanged. The supply pressure persists as some enterprises' production has recovered. The demand for heavy alkali is for rigid needs, and the increase in float glass daily melting is uncertain. The short - term inventory decreased due to maintenance, but the long - term surplus remains [11]. - Outlook: The supply surplus remains, and the price is expected to oscillate weakly in the short term and decline in the long term [11]. Ferrosilicon Manganese - Core Logic: The ferrosilicon manganese price was weak. The cost pressure is high as the market is bearish on raw materials, and the South32 Australian ore is arriving at the port. The supply is increasing, and the demand is weak as the black market enters the off - season [13]. - Outlook: The supply is expected to increase, and the demand is weakening. The price is expected to continue to decline as the manganese ore inventory rises and the coke price is falling [13]. Ferrosilicon - Core Logic: The ferrosilicon price was weak. The supply increased slightly as some furnaces were restarted. The demand is weak as the steel market enters the off - season and the metal magnesium market is sluggish [14]. - Outlook: The supply and demand are both weak, and the demand may weaken further. The price is expected to oscillate under pressure in the short term, and attention should be paid to steel procurement and production [14].

Report Industry Investment Ratings No relevant content provided. Core Views - Crude oil: After OPEC's production increase in July, the previous negative factors were exhausted. With the threat of wildfires in Canada and rising geopolitical risks, combined with short - term macro - stability, oil prices are strong in the short - term. However, in the long - term, due to relatively weak demand and continuous supply growth, the upside space is limited. The short - term Brent price is expected to oscillate at a high level, with the operating range moving up to $65 - 68 per barrel, and the medium - term range is expected to be $63 - 70 per barrel [1][2]. - Asphalt: The overall supply - demand pattern is loose. Although the cost of crude oil has increased, the market's acceptance of high - priced resources is poor. In the short - term, the terminal demand is limited, and the mainstream transaction price is concentrated at the lower end. However, due to the maintenance plan of some refineries and low inventory levels, the price has a certain upward trend [3][4]. - Liquefied gas: In the international market, the CP price has increased, while the FEI has decreased. In the domestic market, supply is increasing, and the summer off - season has increased the pressure on the market, with the fundamentals running weakly [8]. - Fuel oil: High - sulfur fuel oil has high near - month cracking and month - to - month spreads, and the spot premium has rebounded. The supply from Russia, Mexico, and the Middle East is expected to decline, while the demand for seasonal power generation is supportive. Low - sulfur fuel oil has a stable supply increase and weak downstream demand [9][11]. - Natural gas: In the US, due to increased demand, the price is expected to rebound. In Europe, supply restrictions and geopolitical tensions offset weak demand, and the price has returned above 35 euros. Europe still faces challenges in refilling gas storage [12][13]. - PX: As the efficiency of PX improves, the operating rate is expected to increase in June, and the supply - demand situation is expected to improve, with the spot shortage situation expected to ease [14][16]. - PTA: The supply is expected to increase, while the polyester industry plans to reduce production, and the supply - demand relationship is expected to weaken, and the processing fee may be compressed [17][18]. - Ethylene glycol: The inventory is expected to decline in the short - term, but the supply will increase in June due to some restarted maintenance. The downstream polyester operating rate is weakening, and the supply - demand gap is expected to narrow, maintaining a tight balance [20][21]. - Short - fiber: The operating rate is stable, and the terminal demand is mainly for fulfilling previous orders. There are still production reduction plans in June, but the supply loss is limited. The processing fee is expected to be strongly supported [22][23]. - Bottle - chip: The operating rate has decreased, and the processing fee fluctuates within a narrow range. In June, the downstream soft - drink industry will enter the production peak, and the supply - demand situation is expected to be strong, with the processing fee having strong support [24][26]. - Styrene: The supply is expected to increase, and the port inventory is expected to increase from a low level, with the supply - demand relationship weakening [26][27]. - PVC: The supply - demand situation is expected to be weak in the medium - to - long - term, with supply increasing and demand affected by real estate and export uncertainties [29][30]. - Caustic soda: The 09 - contract is expected to be weak, with the medium - term trend being bearish. Although there is still some support in the short - term, the upward driving force for the spot price is weakening [30][31]. - Plastic and PP: The new production capacity is being realized, and the downstream demand is weak. The 09 - contract's supply - demand situation is expected to be weak [32][34]. - Glass: The supply pressure is increasing, and the demand is affected by the real estate cycle. The short - term price is expected to oscillate weakly, and the medium - term focus is on cost reduction and factory cold - repair [34][37]. - Soda ash: The supply is increasing, the cost is weakening, and the demand is stable in the short - term but worrying in the medium - term. The price is expected to decline gradually [38][40]. - Urea: The daily output is at a high level, and the demand is affected by factors such as international price changes, compound fertilizer production, and export policies. The short - term price is expected to oscillate [41][42]. - Methanol: The international supply is still high, the domestic supply is loose, and the port is starting to accumulate inventory. The price is still recommended to be shorted on rebounds [43][45]. - Log: The downstream market is still sluggish, and the long - term market faces challenges from weak real - estate demand and increased port inventory. However, the large scale difference in delivery has a certain supporting effect on the current price [45][48]. - Double - offset paper: The market was weak in May, and in June, short - term technical rebounds may occur, but long - term risks from over - capacity and weak demand need to be vigilant [48][49]. - Corrugated paper: In May, the demand showed structural improvement, but in June, attention should be paid to factors such as the implementation of price - increase policies, export order sustainability, and waste - paper price fluctuations [50]. - Natural rubber: The domestic inventory is still at a high level, and the production index of French rubber machinery has decreased. The short - term trading strategy is to hold short positions [51][54]. - Pulp: The domestic and foreign paper - making industries have shown signs of production reduction, which is negative for the SP single - side. The short - term trading strategy is to try to go long on a small scale [54][56]. - Butadiene rubber: The short - term supply contraction has led to price increases, and in the medium - term, attention should be paid to the expansion of downstream ABS capacity. The short - term trading strategy is to hold short positions [58][60].
