Report Industry Investment Rating - Unilateral: Neutral; Inter - period: 01 - 05 reverse spread; Inter - variety: None [4] Core View - Recently, the cost - end oil price has rebounded, and the external propane price has risen strongly. With the support of macro - sentiment, polyolefins have rebounded slightly with fluctuations. Some upstream petrochemical plants have shut down for maintenance, and the capacity utilization rate has decreased slightly. There is an expectation of new capacity from ExxonMobil, and Daxie Petrochemical is continuously increasing production, so the supply is still under pressure. The downstream demand is in the "Golden September" seasonal improvement stage, with the overall downstream factory operating rate rising slightly. However, the downstream mainly maintains rigid procurement, and the demand fulfillment rate is still slow. PP production profit has shrunk significantly, and the cost - end support is strong [3] Summary by Related Catalogs Market News and Important Data - **Price and Basis**: L main contract closed at 7,245 yuan/ton (+11), PP main contract at 6,982 yuan/ton (+12). LL North China spot was 7,200 yuan/ton (+0), LL East China spot was 7,170 yuan/ton (+0), PP East China spot was 6,780 yuan/ton (+0). LL North China basis was - 45 yuan/ton (-11), LL East China basis was - 75 yuan/ton (-11), and PP East China basis was - 202 yuan/ton (-12) [2] - **Upstream Supply**: PE operating rate was 78.0% (-2.5%), PP operating rate was 76.8% (-3.1%) [2] - **Production Profit**: PE oil - based production profit was 170.9 yuan/ton (-70.8), PP oil - based production profit was - 459.1 yuan/ton (-70.8), and PDH - based PP production profit was - 303.0 yuan/ton (-12.1) [2] - **Import and Export**: LL import profit was - 92.1 yuan/ton (+10.2), PP import profit was - 482.1 yuan/ton (-9.8), and PP export profit was 29.1 US dollars/ton (+1.2) [2] - **Downstream Demand**: PE downstream agricultural film operating rate was 24.1% (+3.9%), PE downstream packaging film operating rate was 51.3% (+0.8%), PP downstream plastic weaving operating rate was 43.1% (+0.4%), and PP downstream BOPP film operating rate was 61.6% (+0.1%) [2] Market Analysis - Cost - end factors and macro - sentiment have driven polyolefins to rebound slightly. Supply is under pressure due to potential new capacity and production increases. Downstream demand is in a seasonal improvement stage, but the demand fulfillment is slow, and PP cost - end support is strong [3] Strategy - Unilateral strategy is neutral; inter - period strategy is 01 - 05 reverse spread; no inter - variety strategy [4]

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: 09 - 01 reverse spread; Inter - variety: Short coal - based profit [3] Core Viewpoints - Policy promotes the orderly exit of backward production capacity, and the macro - level has a certain boost to the polyolefin market. New device overhauls in production enterprises ease some supply - demand pressure, but some devices restart. PE upstream and mid - stream inventory trends continue to rise, and PP production enterprise inventory continues to accumulate. Crude oil is weakly sorted, propane prices continue to be weak, cost - side support is weak. Downstream demand remains weak in the seasonal consumption off - season, and new order volume is limited. In the short - term future, there are no new overhaul plans, and supply is expected to increase. With weak fundamentals, inventory is expected to continue rising [2] Summary by Directory 1.

In the future, with weak fundamentals, inventory is expected to continue rising [2]

Report Industry Investment Rating - The report does not mention the industry investment rating [1][2][3] Core Viewpoints - The fundamentals of polyolefins maintain a loose supply - demand pattern with supply exceeding demand. During the maintenance season of upstream petrochemical plants, the number of maintenance enterprises increases slightly, capacity utilization declines, and new production capacity continues to be released. Overall, the supply side shows an incremental trend. Enterprises' inventories accumulate, and the destocking rate is slow. International oil prices and propane prices remain weak and are expected to continue this way, with weak cost support. PDH - made PP maintains a small profit. In the off - season, downstream demand shows no significant improvement, the operating rate remains low, with mainly rigid - demand purchases and insufficient follow - up of terminal orders [2] Summary by Catalog I. Polyolefin Basis Structure - The report presents the trends of plastic and polypropylene futures' main contracts, as well as the basis between LL East China and the main contract, and PP East China and the main contract [8][11] II. Production Profit and Operating Rate - PE oil - based production profit is 172.1 yuan/ton (+88.6), PP oil - based production profit is - 237.9 yuan/ton (+88.6), and PDH - made PP production profit is 192.5 yuan/ton (-38.7).

Polyolefin Inventory - The report mentions the inventories of PE and PP in oil - based enterprises, coal - chemical enterprises, traders, and ports, but does not provide specific data [72][75][77] Strategies - Unilateral: Neutral; - Inter - period: Reverse spread of 09 - 01; - Cross - variety: Short coal - based profits [3]

Report Industry Investment Rating - The rating for plastics is cautiously bearish, and there is no recommendation for inter - term trading [3] Core View - Downstream demand follow - up is weak, and the market is weakly consolidating. The market has returned to fundamental trading. The downstream demand is in the off - season. The agricultural film operating rate is at a low level, the packaging film operating rate fluctuates slightly, and the operating rates of industries such as plastic weaving and BOPP have slightly increased. The traditional consumption off - season is coming, and terminal factories have low enthusiasm for raw material procurement and general inventory - building enthusiasm, mainly for rigid demand procurement. The number of PE maintenance devices has increased, and the PE supply side has eased. The previously shut - down PP devices have gradually restarted, and the upstream production inventory of polyolefins has decreased. It is expected that the future supply will increase. Due to the easing of Sino - US tariffs, the production profit of PDH - made PP has recovered. Attention should be paid to the restart of shut - down devices [2] Summary by Directory I.
