1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - Geopolitical uncertainties persist, and the supply side continues to provide support for the polyolefin market. The ongoing tensions in the Middle East have led to supply issues for olefin raw materials, causing the market to rebound. For PE, the supply is tightening due to raw material shortages and upstream maintenance, while demand is gradually releasing but with cautious buying. For PP, the supply support remains strong, and although downstream purchasing is weak, the export window has opened, and prices are strongly supported in the short term [3][4] 3. Summary According to the Directory I. Polyolefin Basis and Inter - period Structure - The L main contract closed at 8767 yuan/ton (+52), the PP main contract closed at 9120 yuan/ton (+145).

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Pure Benzene - Styrene - Pure benzene supply is expected to decline due to refinery load reduction and planned maintenance, while downstream product prices are rising, improving the supply - demand outlook. Short - term price may follow oil prices, and the strategy is to wait and see and reduce the EB05 - BZ05 spread when it is high [1]. - Styrene supply remains stable with a mix of restarts and maintenance. Demand is weak in procurement, but the supply - demand is still tight. Short - term price follows oil prices, and the strategy is the same as for pure benzene [1]. Glass - Soda Ash - Soda ash has a pattern of strong supply and weak demand, and the market will be a game between supply - demand and cost support, with an expected weakening trend. Attention should be paid to the support at around 1150 for SA605 [2]. - Glass has a similar situation of supply - demand and cost support game. The market is expected to be weak, and attention should be paid to the support at around 1030 for FG605 [2]. Natural Rubber - As domestic production areas start full - scale tapping, supply pressure will dominate the market. The US - Iran conflict affects tire exports, and rubber prices are expected to face pressure [3]. Crude Oil - Oil prices are expected to maintain wide - range fluctuations, with the main factors being geopolitical support and policy suppression. Short - term focus is on the actual resumption of navigation in the Strait of Hormuz and negotiation progress [4]. Methanol - The current market is dominated by reduced imports. High volatility requires caution regarding demand sustainability and policy risks. The 05 contract is expected to see significant de - stocking [7]. Polyester Industry Chain - PX has a situation of weak supply and demand, and its price is expected to follow oil prices in the short term. The strategy is to wait and see and monitor oil prices [9]. - PTA has limited self - drive, and its absolute price follows the cost side. The strategy is the same as for PX [9]. - Ethylene glycol has upward price momentum in the short term, but attention should be paid to the risk of price decline after the rise [9]. - Short - fiber has weak self - drive and follows raw material fluctuations. The strategy for the PF contract is to expand the processing margin when it is below 800 [9]. - Polyester bottle - chip supply is expected to be tight, and the processing margin of the PR main contract is expected to be strong [9]. PVC - Caustic Soda - Caustic soda's fundamentals have marginally improved, but the overall supply - demand is still weak. The price may be affected by export expectations and downstream demand [10]. - PVC has a weak supply - demand situation, but the overall market price is likely to rise due to the impact of rising energy prices [10]. Urea - Urea supply remains in a loose pattern, and demand is weak. The price is expected to fluctuate and consolidate in the short term, with the main contract focusing on the 1830 - 1900 range [11]. LPG - The LPG market shows price declines in futures contracts. Inventory and upstream - downstream开工率 have some changes, but no clear market trend conclusion is given in the report [12]. Polyolefin - Polyolefins are traded based on the logic of "strong cost, reduced supply", with low valuations. However, demand is limited, and long positions can be reduced [13]. 3.

Report Industry Investment Rating - Not provided in the given content Core Viewpoints - The escalation of military confrontation between the US, Israel, and Iran has led to the blockade of the Strait of Hormuz, causing a sharp rise in the geopolitical risk premium of crude oil. The Brent crude oil futures main contract has reached a two - year high and is fluctuating around $100 per barrel. This price increase will trigger a drastic reconstruction of the entire industrial chain from the cost side and have a profound impact on downstream chemical products and terminal industries [1][3]. - The core driver of the oil price breaking through $100 per barrel is the market's extreme concern about the blockade of the Strait of Hormuz and the complete halt of crude oil exports from Iran and multiple Middle - Eastern countries. The conflict has entered the "energy infrastructure war" stage, bringing multiple cost pressures to the energy - chemical industry chain and compressing the profit margins of downstream manufacturing [4]. - As long as the geopolitical conflict does not substantially ease and the Strait of Hormuz does not have substantial free navigation, the Brent crude oil price will be strongly supported above $90. It is possible for the price to break through the recent high of $119.5 per barrel [7]. - The impact of rising crude oil prices on chemical futures is a complex system with cost - driven as the main factor, supplemented by expectation transmission, regulated by cracking spreads, and restricted by substitution effects. In actual operations, it is necessary to dynamically track the three - level spread structure of crude oil - naphtha - chemical products and combine inventory and production capacity cycles to judge the transmission efficiency [1][16]. Summary by Relevant Catalogs Crude Oil Price Breakthrough and Future Outlook - The current oil price breakthrough is due to concerns about the blockade of the Strait of Hormuz and the halt of Middle - Eastern crude oil exports. The conflict has led to the shutdown of over 7 million barrels per day of crude oil production in the Middle East and brought supply shocks to refined oil and natural gas [4]. - The probability of a short - term agreement between the US and Iran is low, and even if an agreement is reached, the damaged oil and gas production facilities cannot be repaired in the short term. The current supply shock of crude oil exceeds any previous ones [5]. - Global crude oil inventory is at a historical low, and the blockade of the Strait of Hormuz has cut off 20% of global crude oil supply. With stable global demand, the Brent crude oil price will be supported above $90, and it may break through $119.5 per barrel [7]. Chemical Product Price Conduction - The price of crude oil is transmitted downstream along the "crude oil - naphtha - intermediate - synthetic material - product" chain. There is significant differentiation among chemical product varieties [8]. - In the naphtha and olefin chain, naphtha prices rise with crude oil, but cracking spreads are compressed. The prices of basic raw materials such as ethylene and propylene increase, leading to a "high - cost, low - profit" situation for downstream plastics [8]. - In the aromatic hydrocarbon chain (PX - PTA - polyester), PX prices rise with crude oil, driving up PTA prices. However, due to the lack of synchronous growth in textile orders, PTA processing fees are compressed, and some devices face the risk of shutdown [8]. - High oil prices theoretically benefit coal - chemical enterprises, but in the current macro - environment, coal - chemical products have difficulty rising. The attack on Qatar's LNG facilities has led to cost increases for gas - based chemical products, offsetting some of the relative advantages of coal - chemical industry [8]. Core Conduction Mechanism - **Conduction Path**: The price of crude oil is transmitted downstream through the "crude oil - naphtha - intermediate - synthetic material - product" chain [8]. - **Conduction Mechanism**: - **Cost - Push Effect**: The cost of key chemical products increases with the rise of crude oil prices. For example, for every $10 per barrel increase in crude oil, the ethylene cost increases by about $80 - 100 per ton. The correlation between PX and crude oil is as high as 0.85+ [10]. - **Cracking Spread Adjustment**: When the cracking spread expands, refinery profits are good, and the supply of chemical raw materials is sufficient, limiting the increase of chemical product prices. When the spread narrows, refinery profits are compressed, and the supply of chemical raw materials tightens, expanding the increase of chemical product prices [12]. - **Substitution Effect and Marginal Pricing**: The rise of crude oil prices makes coal - based products more economical, suppressing the rise of oil - based chemical products. It also increases the correlation between agricultural products such as corn and palm oil and energy prices [13]. - **Sensitivity Analysis of Different Chemical Products**: - **High Sensitivity (correlation coefficient > 0.7)**: PTA/ethylene glycol, polyolefins (LLDPE/PP), and styrene [15]. - **Medium Sensitivity (correlation coefficient 0.4 - 0.7)**: Methanol, PVC, and synthetic rubber [15]. - **Low Sensitivity (correlation coefficient < 0.4)**: Urea, soda ash, and glass/building material - related chemical products [15].

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - The current situation in Iran remains a crucial factor influencing the prices of olefin products. The news of the US - Iran peace talks on the evening of March 23 led to a decline in the polyolefin futures market. However, the negotiation progress is expected to face difficulties, and the subsequent development of the situation needs to be monitored [1][3]. - For PE, the upstream maintenance plans are increasing, and the expected import resources are weak, resulting in a continuous tightening of market supply. On the demand side, although the overall downstream开工率 has increased, the high - price acceptance of downstream buyers is low, leading to a significant decline in the L basis. In the short term, without actual signs of US - Israel troop withdrawal or successful negotiations, the cost support and supply concerns for PE remain [4]. - For PP, the concerns about raw material supply are intensifying, and the supply support remains strong. The demand side shows that high prices squeeze downstream profits, and downstream procurement is cautious. However, the opening of the export window has boosted export demand. In the short term, the reduction in PP supply and the strong cost support from propane continue to resonate, and prices remain strongly supported before the Strait of Hormuz re - opens for navigation [4]. - The recommended strategy is to cautiously go long on LLDPE and PP for hedging on dips, with no recommendations for inter - period or cross - variety trading [5]. 3. Summary According to the Catalog 3.1 Market News and Important Data - **Price and Basis**: The closing price of the L main contract is 8,918 yuan/ton (- 605), and that of the PP main contract is 9,114 yuan/ton (- 679). The LL spot price in North China is 8,800 yuan/ton (+ 0), in East China is 8,950 yuan/ton (- 150), and the PP spot price in East China is 9,200 yuan/ton (- 100). The LL basis in North China is - 118 yuan/ton (+ 605), in East China is 32 yuan/ton (+ 455), and the PP basis in East China is 86 yuan/ton (+ 579) [1]. - **Upstream Supply**: The PE operating rate is 80.1% (- 2.3%), and the PP operating rate is 70.5% (+ 0.4%) [1]. - **Production Profit**: The PE oil - based production profit is - 51.6 yuan/ton (+ 1,566.3), the PP oil - based production profit is - 91.6 yuan/ton (+ 1,566.3), and the PDH - based PP production profit is - 3,034.3 yuan/ton (+ 108.0) [1]. - **Imports and Exports**: The LL import profit is - 300.5 yuan/ton (+ 661.9), the PP import profit is - 1,012.9 yuan/ton (+ 397.0), and the PP export profit is 107.0 US dollars/ton (- 72.1) [1]. - **Downstream Demand**: The PE downstream agricultural film operating rate is 35.4% (+ 8.6%), the PE downstream packaging film operating rate is 45.6% (+ 2.2%), the PP downstream plastic weaving operating rate is 40.3% (- 0.3%), and the PP downstream BOPP film operating rate is 62.0% (+ 0.6%) [2]. 3.2 Market Analysis - The Iran situation is a key factor affecting olefin prices. After the news of the US - Iran peace talks on March 23, there were different stances from both sides, and the negotiation progress is expected to be difficult. The subsequent attitude of Iran needs to be continuously monitored [3]. - For PE, the supply is tightening due to more maintenance plans and weak import expectations. The demand side shows a negative feedback, and the L basis has declined significantly. The cost support and supply concerns remain in the short term [4]. - For PP, the supply support is strong due to increased maintenance losses. The demand side is cautious, but the export demand has increased. The short - term price is strongly supported by supply reduction and cost factors [4]. 3.3 Strategy - **Single - sided**: Cautiously go long on LLDPE and PP for hedging on dips [5]. - **Inter - period**: No strategy recommended [5]. - **Cross - variety**: No strategy recommended [5].
