Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - Trump's statement on the cease - fire between Israel and Iran led to a sharp drop in oil prices at the opening, causing a general decline in chemical products. PE supply is contracting due to the conflict - related shutdown of Iranian polyolefin plants and domestic PE device maintenance, while demand is mainly for刚需 restocking in the off - season. Overall, the current supply - demand pressure of PE is not significant, and attention should be paid to import arrivals and full - density device conversion [3]. 3. Summary by Relevant Catalogs Price Forecast and Volatility - The monthly price range forecast for polyethylene is 7000 - 7400. The current 20 - day rolling volatility is 15.74%, and its historical percentile over 3 years is 40.1% [2]. Hedging Strategies - **Inventory Management** - For high - inventory situations worried about price drops, shorting L2509 futures at a 25% hedging ratio in the 7300 - 7400 range can prevent inventory depreciation. Selling L2509C7300 call options at a 50% ratio in the 70 - 120 range can collect premiums and lock in selling prices [2]. - For low - inventory situations, buying L2509 futures at a 50% ratio in the 7100 - 7200 range can prevent price increases in procurement. Selling L2509P7100 put options at a 75% ratio in the 50 - 100 range can collect premiums and lock in buying prices [2]. Core Contradictions - Supply contraction: The Israel - Iran conflict led to plant shutdowns in Iran, and domestic PE devices are in maintenance, with full - density device conversion reducing the supply of standard products. Demand is mainly for刚需 restocking in the off - season. Attention should be paid to import arrivals and full - density device conversion [3]. Bullish Factors - PE devices are in seasonal maintenance until July. The high HDPE - LLDPE price difference leads to full - density device conversion, and low HDPE inventory can absorb the supply pressure. The Israel - Iran conflict may reduce PE imports from Iran [4]. Bearish Factors - Multiple HDPE devices are planned to be put into operation in the middle of the year. The off - season and low - profit environment reduce domestic demand [5]. Market Data - **Futures Prices and Spreads** - The plastic main - contract basis, L01, L05, and L09 contracts all showed certain changes compared to previous days and weeks. Month - to - month spreads (L1 - 5, L5 - 9, L9 - 1) and the L - P spread also had significant changes [6][8]. - **Spot Prices and Regional Spreads** - Spot prices in North China, East China, and South China changed, and regional spreads (East - North, East - South) also showed fluctuations [8]. - **Non - standard and Standard Product Spreads** - Spreads between various HDPE products and LLDPE films, as well as between LDPE and LLDPE films, changed [8]. - **Upstream Prices and Processing Profits** - Brent crude oil prices, US ethane prices, coal prices, and methanol prices all changed, affecting the processing profits of different PE production methods [8].

Report Summary 1. Price Forecast and Volatility - The monthly price range forecast for polyethylene is 7000 - 7400, with a current 20 - day rolling volatility of 12.33% and a 3 - year historical percentile of 21.8% [2] 2. Hedging Strategies Inventory Management - When inventory is high and there are concerns about price drops, for finished product inventory, shorting plastic futures (L2509) with a 25% hedging ratio at 7350 - 7400 can lock in profits and cover production costs; selling call options (L2509C7400) with a 50% ratio at 70 - 120 can collect premiums and lock in selling prices if prices rise [2] Procurement Management - When procurement inventory is low and based on order - based procurement needs, buying plastic futures (L2509) with a 50% ratio at 7000 - 7100 can lock in procurement costs; selling put options (L2509P7100) with a 75% ratio at 50 - 100 can collect premiums and lock in buying prices if prices fall [2] 3. Core Contradiction - Due to the Middle - East geopolitical situation, the polyolefin market has strengthened, but the current supply - strong and demand - weak situation in the PE market remains unchanged. The high HD - LL spread and good HDPE supply - demand with low inventory may lead to more full - density plant conversions, potentially alleviating LLDPE supply pressure. The Middle - East situation may also disrupt PE imports and support prices through higher oil costs, but price upside may be limited due to supply surplus [3] 4. Bullish Factors - The high HDPE - LLDPE spread may lead to more full - density plant conversions; the Middle - East tension drives up oil prices, supporting polyolefins; the Iran - related conflict may reduce PE imports from Iran [4] 5. Bearish Factors - Multiple HDPE plants are planned to be put into operation in the middle of the year; the downstream off - season and low - profit environment reduce domestic demand [5] 6. Market Data Futures Prices and Spreads - The plastic main contract basis on 2025 - 06 - 18 was 58 yuan/ton lower than on 2025 - 06 - 17 and 98 yuan/ton lower than on 2025 - 06 - 11. There were also various price differences among different L contracts and spreads such as L1 - 5, L5 - 9, L9 - 1, and L - P [6][8] Spot Prices and Regional Spreads - There were price differences in different regions (North China, East China, South China) and spreads between regions such as East - North and East - South [8] Non - standard and Standard Product Spreads - There were price differences between HDPE (membrane, hollow, injection,拉丝, pipes) and LDPE membranes compared to LLDPE membranes [8] Upstream Prices and Processing Profits - Brent crude oil price was 75 dollars/barrel, with a 5.98 dollars/barrel increase compared to before. There were also prices and profit data for other upstream products and different PE production methods [8]

Report Overview - Report Industry Investment Rating: Not provided - Report Core View: The current PE market shows a pattern of weak supply and demand. The supply side is in a centralized maintenance season, but the high - capacity growth still leads to an overall supply increase. The demand side is affected by low - profit environments and the off - season, with no obvious demand drivers. Attention should be paid to the conversion of full - density devices due to the high HD - LL spread [2]. Price Forecast - Monthly price range forecast for polyethylene is 6900 - 7200 yuan/ton, with a current 20 - day rolling volatility of 14.45% and a 3 - year historical percentile of 33.8% [1]. Hedging Strategies Inventory Management - For producers with high product inventory worried about price drops: - Short 25% of L2509 plastic futures at 7100 - 7150 yuan/ton to lock in profits and cover production costs [1]. - Sell 50% of L2509C7200 call options at a premium of 70 - 120 yuan/ton to reduce costs and lock in the spot selling price if the price rises [1]. Procurement Management - For buyers with low regular inventory and wanting to purchase according to orders: - Buy 50% of L2509 plastic futures at 6900 - 7000 yuan/ton to lock in procurement costs [1]. - Sell 75% of L2509P6900 put options at a premium of 50 - 100 yuan/ton to reduce procurement costs and lock in the spot purchase price if the price drops [1]. Market Factors Bullish Factors - PE devices are in a seasonal maintenance period, and the centralized maintenance season is expected to last until July [3]. - The current futures price is at a relatively low level, with limited downward space [3]. - The high HDPE - LLDPE spread may lead to more conversions of full - density devices [3]. Bearish Factors - Multiple HDPE devices are planned to be put into operation in the middle of the year [7]. - The off - season of downstream production and sales and the low - profit environment have led to a decrease in domestic demand [7]. - Although the plastic spot has shown signs of price support recently, the overall trading volume is weak [7].

1. Report Industry Investment Rating - Not provided 2. Core Viewpoints - The recent core contradiction of PE is that the weak supply - demand pattern restricts its upward space. On the supply side, although PE plants are in the centralized maintenance season with marginal supply reduction, the production is still much higher than the same period in previous years due to many new productions at the beginning of the year. On the demand side, the low - profit environment suppresses the operating rate, and the agricultural film is in the off - season, so there is no incremental demand driver [2]. - There are some positive factors, including PE plants entering the seasonal maintenance season which is expected to last until July, and the current futures price being at a relatively low level with limited downward space [3]. - There are also negative factors, such as the planned commissioning of multiple HDPE plants in the middle of the year, the reduction of domestic demand due to the off - season of downstream production and sales and the low - profit environment, and the continuous weakness of the plastic spot market with the basis in North China turning from positive to negative [4]. 3. Summary by Relevant Content 3.1 Price Forecast - The monthly price range forecast for polyethylene is 6900 - 7200 yuan/ton, the current 20 - day rolling volatility is 14.63%, and the historical percentile of the current volatility in the past 3 years is 34.7% [1]. 3.2 Hedging Strategies Inventory Management - When the inventory of finished products is high and there are concerns about falling plastic prices, for long - position inventory, it is recommended to short plastic futures (L2509) with a hedging ratio of 25% and enter the market at 7100 - 7150 yuan/ton to prevent inventory depreciation losses and lock in profits; also, sell call options (L2509C7200) with a hedging ratio of 50% and a premium range of 70 - 120 yuan to reduce costs and lock in the spot selling price if the polyethylene price rises [1]. Procurement Management - When the procurement of regular inventory is low and there is a need to purchase according to orders, for short - position inventory, it is recommended to buy plastic futures (L2509) with a hedging ratio of 50% and enter the market at 6900 - 7000 yuan/ton to prevent the increase in procurement costs due to rising polyethylene prices; also, sell put options (L2509P6900) with a hedging ratio of 75% and a premium range of 50 - 100 yuan to reduce procurement costs and lock in the spot purchase price if the polyethylene price falls [1]. 3.3 Market Data Futures Prices and Spreads - On June 6, 2025, the plastic main - contract basis was 119 yuan/ton, showing a daily decrease of 12 yuan/ton and a weekly decrease of 36 yuan/ton.

Report Industry Investment Rating - Not provided Core Viewpoints - Today, polyethylene followed the rise of coking coal, but its own fundamentals changed little. On the supply side, PE plants are in the peak maintenance season, with a marginal decrease in supply. However, due to the large number of new plant startups at the beginning of the year, production is still significantly higher than the same period in previous years. On the demand side, the low - profit environment suppresses the operating rate, and the agricultural film is in the off - season of production and sales, resulting in weak demand [2] - There are both positive and negative factors. Positive factors include PE plants entering the seasonal maintenance period, which is expected to last until July, and the current futures price being at a relatively low level with limited downward space. Negative factors include the planned startups of multiple HDPE plants in the middle of the year and the reduction in domestic demand due to the off - season of downstream production and sales and the low - profit environment [3][4][5] Summary by Relevant Catalogs Polyethylene Price Range Forecast - The monthly price range forecast for polyethylene is 6900 - 7200 yuan/ton, with a current 20 - day rolling volatility of 14.89% and a historical percentile of 36.3% over the past 3 years [1] Polyethylene Hedging Strategy - **Inventory Management (High finished - product inventory, worried about price decline)**: For the long - position in the spot market, it is recommended to short L2509 plastic futures with a 25% hedging ratio at an entry range of 7100 - 7150 yuan/ton to lock in profits and cover production costs. Also, sell L2509C7200 call options with a 50% hedging ratio at an entry range of 70 - 120 to collect premiums and reduce costs, and lock in the spot selling price if the price rises [1] - **Procurement Management (Low regular inventory, want to purchase according to orders)**: For the short - position in the spot market, it is recommended to buy L2509 plastic futures with a 50% hedging ratio at an entry range of 6900 - 7000 yuan/ton to lock in procurement costs in advance. Also, sell L2509P6900 put options with a 75% hedging ratio at an entry range of 100 - 130 to collect premiums and reduce procurement costs, and lock in the spot purchase price if the price falls [1] Polyethylene Daily Data Futures Prices and Spreads - The plastic main - contract basis on June 4, 2025, was 116 yuan/ton, showing a daily change of - 86 yuan/ton and a weekly change of - 77 yuan/ton.
