Report Industry Investment Ratings - Urea: ★☆☆ (One star, indicating a bullish/bearish bias, with a driving force for price increase/decrease, but limited operability on the trading floor) [1] - Methanol: ★★★ (Three stars, representing a clearer bullish/bearish trend and a relatively appropriate investment opportunity currently) [1] - Styrene: ★★☆ (Two stars, suggesting a clear bullish/bearish trend and the market situation is evolving) [1] - Polypropylene: ★★★ [1] - Plastic: ★★☆ [1] - PVC: ★★☆ [1] - Caustic Soda: ★☆☆ [1] - PTA: ★☆☆ [1] - Ethylene Glycol: ★☆☆ [1] - Short Fiber: ★★★ [1] - Glass: ★★★ [1] - Soda Ash: ☆☆☆ (White star, meaning the short - term bullish/bearish trend is in a relatively balanced state, and the current trading floor has poor operability, suggesting to wait and see) [1] - Bottle Chip: ★☆☆ [1] Core Views - The chemical market shows a mixed trend, with some products expected to be weak, some in a balanced state, and some showing potential investment opportunities. Each product's performance is influenced by factors such as supply and demand, cost, and seasonal factors [2][3][4] Summary by Product Categories Methanol - Intraday price oscillated with reduced positions. Coastal olefins increased load, raising methanol external procurement demand. Ports gradually accumulated inventory, and the basis remained strong. Inland device maintenance restarts increased, leading to higher load and weaker prices. Coal prices stopped falling, alleviating cost pressure. With the expectation of increased supply, the methanol market is expected to be weakly volatile, and attention should be paid to the impact of Jiangsu Maritime's ship - age restrictions [2] Urea - Futures prices dropped sharply with increased positions, breaking through the low in late April. Agricultural demand is in the wheat - harvest gap. With the end of summer high - nitrogen fertilizer production and clear export policies, market trading sentiment weakened, and producers' inventories continued to accumulate. Although exports are gradually liberalized, legal inspections are still restricted, and port inventories are basically the same as last week. A new Indian tender has little impact on the market. Device maintenance increased slightly, and the load decreased slightly but remained high. Short - term attention should be paid to the support at the integer level [3] Polyolefins - Futures main contracts fluctuated narrowly. For polyethylene, there are still many maintenance plans in June, providing some support on the supply side. However, it is the off - season for demand, and end - users mainly replenish inventory at low prices, providing limited support for spot prices. For polypropylene, downstream demand is in the off - season, and the willingness of downstream buyers to take delivery is average. The market lacks clear signals, and market sentiment is cautious. The restart of previously maintained upstream devices and inventory accumulation during holidays have increased supply pressure, and the supply - demand contradiction is expected to intensify with the upcoming launch of new devices [4] Styrene - The main futures contract fluctuated narrowly, and the overall center of gravity moved down along the 5 - day moving average. There is an expectation of increased supply, and producers' intention to sell is strong, suppressing downstream replenishment transactions. Producers are gradually reducing prices, and downstream users are using existing raw materials and purchasing on an as - needed basis, with weak market sentiment [6] Polyester - PX and PTA futures prices declined first and then oscillated back, remaining weak overall. PX and PTA operating rates continued to increase, while polyester capacity utilization decreased slightly, and terminal weaving load decreased. The industry chain shows a situation of increased upstream production and decreased downstream load, and PX and PTA are expected to be under continuous pressure. Attention should be paid to terminal orders and potential production cuts. Ethylene glycol prices rose rapidly due to the suspension of ethane shipments from the US but then oscillated back, and the monthly spread remained weak. With the commissioning of new plants and the restart of coal - chemical plants, port arrivals increased from a low level, and ports accumulated inventory. Coupled with possible weakening demand, market sentiment turned weak. Short - fiber prices were weakly volatile, with low processing margins. Terminal orders weakened, and supply - demand drivers were downward, mainly following raw material price fluctuations. Bottle - chip production is mainly for peak - season orders, and inventory is stable. As raw material prices weakened, the processing margin on the futures market rebounded from a low level, while the spot processing margin continued to weaken [7] Chlor - alkali - PVC continued its weak pattern. With less maintenance in June and the expected commissioning of a 500,000 - ton new plant, supply pressure increased. With the arrival of the Indian rainy season, exports are expected to weaken, and domestic demand is weak, so the PVC industry faces inventory accumulation pressure. The decline in calcium carbide prices has undermined cost support. In a weak supply - demand situation, futures prices may oscillate at a low level. Caustic soda is operating weakly. The increase in liquid chlorine prices has improved the comprehensive profit of chlor - alkali, with a capacity utilization rate of 83.5%. Liquid caustic soda inventory has decreased but still faces pressure. The enthusiasm of non - aluminum downstream users and traders to take delivery is average. Downstream rigid demand has not improved significantly. With high - profit margins, supply is operating at a high level, and futures prices are under pressure at high levels [8] Glass and Soda Ash - Glass continued the pattern of inventory accumulation and price reduction, and futures prices were weak. Affected by the Dragon Boat Festival holiday, the enthusiasm of traders to purchase decreased, and the industry continued to accumulate inventory. Currently, inventory is concentrated in upstream and mid - stream, with high pressure. With the upcoming rainy season, the industry faces shipment pressure. Coal production lines still have profits, with two new production lines and three ignition lines recently, slightly increasing capacity. Processing orders have not improved significantly month - on - month and are still weak year - on - year, and downstream payment collection is poor. With high inventory pressure, the driving force is still weak. At a low valuation, attention should be paid to cost - side changes, and operations should be cautious. Soda ash supply has rebounded to 700,000 tons, with high inventory pressure, and futures prices continued the weak pattern. There are few maintenance plans in June. After upstream price concessions, the industry still has profits, and supply will remain at a high level. Downstream users mainly make rigid purchases and have a weak willingness to replenish inventory. There is a trend of inventory accumulation in the photovoltaic industry, and the subsequent ignition speed will slow down or even cold - repair may occur. Short - term attention should be paid to cost - side fluctuations, and in the long term, supply pressure remains, so a high - level short - selling strategy is recommended [9]

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The methanol market showed a trend of first falling and then stabilizing. Inland methanol prices stopped falling and stabilized in the second half - week due to factors such as increased willingness of traders to hold goods and short - covering demand after prices hit a one - year low. Port prices also showed a similar trend, with the futures market supported by the news of the suspension of the US tariff policy [5]. - It is expected that the methanol price will fluctuate this week, with the MA2509 contract oscillating between 2250 - 2320 yuan/ton [5]. 3. Summary According to the Directory 3.1 Daily Tips - For the methanol 2509 contract, the fundamental situation is neutral; the basis shows that the spot in Jiangsu is at a premium to the futures, which is bullish; the inventory situation is bullish; the disk situation is neutral; the main position is net short with a reduction in short positions, which is bearish [5]. 3.2 Multi - and Short - term Concerns - **Bullish factors**: Some domestic devices such as Yulin Kaiyue and Xinjiang Xinya are shut down; the methanol production start - up rate in Iran has decreased; the port inventory is at a low level; a 600,000 - ton/year acetic acid device in Jingmen has produced products, and a 600,000 - ton/year acetic acid device in Xinjiang Zhonghe Hezhong is planned to be put into production this month; CTO plants in the northwest are purchasing methanol externally [6]. - **Bearish factors**: Some previously shut - down domestic devices such as Inner Mongolia Donghua have resumed operation; there is expected to be a concentrated arrival of ships at ports in the second half of the month; the formaldehyde industry has entered the traditional off - season; the MTBE start - up rate has dropped significantly; coal - to - methanol has a certain profit margin and is actively selling goods; some factories in the production areas have accumulated inventory due to poor sales [7]. 3.3 Fundamental Data - **Price data**: In the spot market, the price of thermal coal in the Bohai Rim and Jiangsu has decreased, while the price of methanol in some regions such as Hebei, Fujian, and Inner Mongolia has increased. In the futures market, the closing price of the main contract has increased, and the number of registered warrants and effective forecasts has also changed. The basis, import spread, and other spreads have also shown corresponding changes [8]. - **Start - up rate data**: The start - up rates in Shandong, Southwest, and Northwest regions have decreased, while the start - up rate in the East China region remains unchanged. The national weighted average start - up rate has decreased [8]. - **Inventory data**: The total social inventory of methanol in the East and South China ports has increased slightly, while the overall available circulating supply in coastal areas has decreased [5]. 3.4 Maintenance Status - **Domestic device maintenance**: Multiple domestic methanol production enterprises in different regions such as Northwest, North China, East China, Southwest, and Northeast are in a state of maintenance, including planned maintenance, unplanned maintenance, and maintenance due to device failures [56]. - **Foreign device operation**: Some Iranian methanol devices are in the process of resuming operation, while devices in other countries such as Saudi Arabia, Malaysia, and the United States are generally operating normally, with some devices having just completed maintenance or having low start - up rates [57]. - **Olefin device operation**: Some domestic olefin devices using methanol as raw material are operating stably, while some are in a state of shutdown or have low loads, and some new projects are planned to be put into production [58].

Report Summary 1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints - This week, the spot price of domestic butadiene rubber in the market dropped from a high level. Due to strong demand for raw material butadiene and unexpected shutdown of some plants, the production cost of butadiene rubber has increased significantly. Although most private butadiene rubber plants in North China have reduced their production to varying degrees, the weak downstream demand has led to increased inventory in production enterprises and sample trading enterprises. It is expected that the inventory of trading enterprises will decline in the short term. The capacity utilization rate of domestic tire enterprises has continued to increase this week, but the production schedule of some enterprises has been slightly adjusted, and a few enterprises have maintenance plans at the end of the month, which may affect the overall capacity utilization rate. The br2507 contract is expected to fluctuate in the range of 11,500 - 12,000 in the short term [7]. 3. Summary by Directory 3.1 Week - to - Week Highlights - **Market Review**: The spot price of domestic butadiene rubber dropped from a high level this week. As of May 21, the mainstream price of Daqing BR9000 in the Shandong market was around 12,200 yuan/ton [7]. - **Market Outlook**: The price of raw material butadiene has continued to rise, increasing the production cost of butadiene rubber. The inventory of production enterprises and sample trading enterprises has increased, and it is expected that the inventory of trading enterprises will decline in the short term. The capacity utilization rate of domestic tire enterprises has continued to increase, but the production schedule adjustment of some enterprises and maintenance plans of a few enterprises may affect the overall capacity utilization rate [7]. - **Strategy Recommendation**: The br2507 contract is expected to fluctuate in the range of 11,500 - 12,000 in the short term [7]. 3.2 Futures and Spot Markets - **Futures Market** - The price of the synthetic rubber futures main contract fluctuated and closed down this week, with a weekly decline of 3.96% [11]. - As of May 23, the 6 - 7 spread of butadiene rubber was - 85 [18]. - As of May 23, the butadiene rubber warehouse receipts were 6,790 tons, a decrease of 190 tons from last week [21]. - **Spot Market** - As of May 22, the price of Qilu Petrochemical BR9000 in the Shandong market was 12,200 yuan/ton, a decrease of 350 yuan/ton from last week [25]. - As of May 22, the basis of butadiene rubber was 170 yuan/ton, a decrease of 120 yuan/ton from last week [25]. 3.3 Industrial Situation - **Upstream** - As of May 22, the CFR mid - price of naphtha in Japan was 563.38 US dollars/ton, a decrease of 2 US dollars/ton from last week; the CIF mid - price of Northeast Asian ethylene was 780 US dollars/ton, unchanged from last week [28]. - As of May 23, the weekly capacity utilization rate of butadiene was 67.73%, a decrease of 0.29% from last week; the port inventory of butadiene was 28,200 tons, a decrease of 2,670 tons from last week [31]. - **Industry** - In April 2025, the domestic butadiene rubber production was 121,500 tons, a decrease of 6,800 tons from the previous month.

Report Overview - Report Title: Weekly Report on Soybean Meal and Soybean Oil Futures [2] - Report Period: May 19 - 23, 2025 [1] 1. Soybean Meal Futures 1.1 Investment Rating - Not provided 1.2 Core View - The soybean meal futures price is expected to continue its weak oscillatory consolidation in the medium - term, and short - term M2509 is expected to oscillate weakly in the range of 2850 - 3000 [6][10] 1.3 Section Summaries 1.3.1 Medium - term Market Analysis - Medium - term trend: The main soybean meal contract is in a stage of weak oscillatory consolidation [6] - Trend logic: In the 19th week, the actual soybean crushing volume of oil mills was 1.846 million tons, with an operating rate of 51.89%. Soybean inventory was 5.3491 million tons, a week - on - week increase of 0.6027 million tons (12.70%); soybean meal inventory was 101,200 tons, a week - on - week increase of 19,100 tons (23.26%). The concentrated listing of Brazilian soybeans and the easing of Sino - US trade relations have led to a more abundant global soybean supply. The increase in domestic imports and the recovery of the oil mill operating rate have strengthened the loose pattern of soybean meal. However, the current terminal breeding feed demand is fair, and the historically low soybean meal inventory restricts the phased release of supply, providing some support for prices [6] - Strategy suggestion: It is recommended to wait and see [6] 1.3.2 Variety Trading Strategy - Last week's strategy review: The overall trend of the soybean meal futures price was in a downward channel, with slightly more funds on the long side. M2509 was expected to continue its weak oscillation in the short term, with an operating range of 2850 - 3000, and interval operations could be considered [9] - This week's strategy suggestion: The overall trend of the soybean meal futures price is in a downward channel, with slightly more funds on the short side. Under the loose supply pattern, M2509 is expected to oscillate weakly in the short term, with an operating range of 2850 - 3000, and interval operations can be considered [10] - Variety diagnosis: The long - short flow is - 48.5, indicating that the main force is slightly bearish; the capital energy is 12.7, and the funds are basically stable; the long - short divergence is 96.1, indicating a high risk of market reversal [13] 1.3.3 Relevant Data - Data sources include Wind, Mysteel, and the Trading Consultation Department of Great Wall Futures [17][20][22] - Relevant data include weekly production, weekly inventory, apparent consumption, weekly inventory days, basis, and oil - meal ratio of soybean meal [17][19][22] 2. Soybean Oil Futures 2.1 Investment Rating - Not provided 2.2 Core View - The soybean oil futures price is expected to continue its range - bound oscillation in the medium - term, and short - term Y2509 is expected to maintain the range - bound oscillation pattern in the range of 7650 - 8000 [27][31] 2.3 Section Summaries 2.3.1 Medium - term Market Analysis - Medium - term trend: The overall trend of the main soybean oil contract continues the range - bound oscillation [27] - Trend logic: According to Mysteel data, in the 19th week, the actual soybean oil production of 125 oil mills was 350,700 tons, an increase of 61,400 tons from the previous week. The commercial inventory of soybean oil in key national regions was 654,400 tons, an increase of 27,600 tons from the previous week. With the increase in soybean supply to oil mills and the recovery of the operating rate, the increase in crushing volume has led to a more abundant soybean oil supply, but weak terminal consumption has kept market transactions sluggish. The current soybean oil inventory is still at a historical low, and the easing of Sino - US trade relations has improved the macro sentiment, providing support. However, the uncertainty of the US biodiesel policy and the fluctuations in crude oil prices have added to market disturbances [27] - Strategy suggestion: It is recommended to wait and see [27] 2.3.2 Variety Trading Strategy - Last week's strategy review: The overall trend of the soybean oil futures price was in a sideways consolidation stage, with more funds on the long side. It was expected to maintain the range - bound oscillation in the short term. The operating range of Y2509 was 7650 - 8000, and interval operations could be considered [30] - This week's strategy suggestion: The overall trend of the soybean oil futures price is in a sideways consolidation stage, with more funds on the short side. Due to the loose supply - demand situation of soybean oil futures, combined with crude oil fluctuations and policy disturbances, it is expected to maintain the range - bound oscillation pattern in the short term. The operating range of Y2509 is 7650 - 8000, and interval operations can be considered [31] - Variety diagnosis: The long - short flow is - 56.5, indicating that the main force is relatively bearish; the capital energy is - 2.2, and the funds are basically stable; the long - short divergence is 63.0, indicating a low risk of market reversal [34] 2.3.3 Relevant Data - Data sources include Wind, Mysteel, and the Trading Consultation Department of Great Wall Futures [40][44][49] - Relevant data include weekly production, weekly inventory, basis, trading volume of soybean oil, as well as weekly arrival volume, weekly inventory, weekly crushing volume, weekly operating rate of soybeans, and weekly port inventory [38][41][45]

Group 1: Report Summary - The investment rating of the report is not provided [N/A] - The core view of the report is that both the soda ash and glass markets are facing challenges. The soda ash market is pressured by high inventory, weak demand, and potential new capacity. The glass market is also affected by low demand and high inventory, but may experience a technical rebound near the cost line. Investors are advised to closely monitor real - estate data and enterprise cold - repair dynamics [7] Group 2: Week - on - Week Summary Market Review - This week, the soda ash futures fell 1.23%, and the glass futures fell 2.8%. The soda ash futures were weak, and the glass futures continued their downward trend. The demand for soda ash from the photovoltaic glass industry slowed down, and the high inventory suppressed the price of soda ash. The glass market was pessimistic, and the bottom - cost support was difficult to maintain [7] Market Outlook - For soda ash, supply contraction is limited due to full production of some enterprises and potential new capacity. Demand is weak, and high inventory continues to suppress prices. The price is expected to continue to decline. For glass, supply may increase, demand is weak, and high inventory restricts price increases. There may be a technical rebound near the cost line [7] Strategy Recommendations - For the SA2509 contract, short - term trading is recommended in the range of 1250 - 1320, with stop - loss in the range of 1230 - 1360. For the FG2509 contract, trading in the range of 990 - 1080 is recommended, with stop - loss in the range of 960 - 1120 [7] Group 3: Futures and Spot Market Futures Price - This week, the soda ash futures price rose, and the glass futures price fell [9] Basis - The soda ash spot price rebounded, and the basis strengthened. As of May 16, 2025, the mainstream price of heavy - soda ash in the Shahe market was 1340 yuan/ton, up 30 yuan/ton week - on - week, and the basis was 51 yuan/ton. The glass spot price fell more than the futures price, and the basis weakened. As of May 16, 2025, the price of 5.0mm large - plate glass in Shahe was 1076 yuan/ton, down 48 yuan/ton, and the basis was 70 yuan/ton [19][27] Spread - The soda ash - glass spread continued to strengthen, mainly due to the over - decline of glass. As of May 16, 2025, the glass - soda ash spread was 284 yuan/ton [29][31] Group 4: Industry Chain Analysis Production and Supply - The domestic soda ash operating rate and production decreased significantly this week. As of May 16, 2025, the national soda ash operating rate was 78.76%, down 8.57% week - on - week, and the national soda ash weekly output was 67.77 tons, down 6.3 tons week - on - week. The number of domestic glass production lines remained unchanged, but the daily output increased slightly. As of May 16, 2025, the daily output of national float glass was 15.67 tons, up 0.16 tons week - on - week. The operating rate, capacity utilization, and daily melting volume of domestic photovoltaic glass remained flat [33][44][48] Profitability - The profit of domestic soda ash enterprises increased this week, while the profit of glass enterprises declined. As of May 16, 2025, the theoretical profit of soda ash by the dual - ton soda - making method was 287.50 yuan/ton, up 12.50 yuan/ton week - on - week, and the theoretical profit of soda ash by the ammonia - soda method was 65.40 yuan/ton, up 15 yuan/ton week - on - week. The profit of glass enterprises by different production methods all declined [39][42] Inventory - The inventory of domestic soda ash enterprises decreased, while the inventory of glass enterprises increased. As of May 16, 2025, the inventory of soda ash enterprises was 171.2 tons, up 1.13 tons week - on - week, and the inventory of glass enterprises was 6808.2 million weight boxes, up 52.2 million weight boxes week - on - week [54][56] Downstream Demand - The deep - processing orders of domestic glass increased compared with last week but were still at a historical low. As of May 15, 2025, the average order days of national deep - processing sample enterprises was 10.4 days [58][60]
