塑料产业周报：悲观情绪带动下跌，近期政策动向为关注重点-20251019

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - In the short - term, polyolefins continued their downward trend this week, mainly driven by macro - sentiment and upstream cost fluctuations, with limited fundamental drivers. The market should focus on whether Sino - US trade frictions will escalate and if new stimulus policies will be introduced during the 20th Fourth Plenary Session. It is recommended to wait and see for unilateral trading [7]. - In the long - term, due to the large number of new PE installations planned to be put into production in the fourth quarter, the supply is expected to increase further. Without new demand - boosting policies, the supply - demand pressure of PE is difficult to resolve, and the weak pattern is expected to continue [8]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - Supply - demand aspect: The PE supply - demand pattern has not changed much. In October, the device maintenance volume decreased compared to September, and supply returned to a high level. Overseas PE supply - demand is weak, and import is expected to increase from October to November, intensifying supply pressure. Although it is the traditional peak season, demand recovery is slow, downstream orders are insufficient, and enterprises' willingness to replenish inventory is low. PE inventory, especially LLDPE inventory, is at a high level, and the upstream and mid - stream face great shipment pressure [2]. - Macro aspect: The continuous shutdown of the US government and market concerns about credit risks have increased risk - aversion sentiment in the financial market, putting downward pressure on crude oil. Sino - US trade policies are still uncertain, and if trade frictions escalate, it may lead to further price drops in crude oil and chemical products. The 20th Fourth Plenary Session next week is worth attention, and new stimulus policies may boost market sentiment [2]. 3.1.2 Trading Strategy Recommendations - Near - term trading logic: The market should focus on Sino - US trade frictions and new stimulus policies during the 20th Fourth Plenary Session. It is recommended to wait and see for unilateral trading [7]. - Long - term trading expectation: The supply - demand pressure of PE is difficult to resolve, and the weak pattern is expected to continue [8]. 3.1.3 Industrial Customer Operation Recommendations - Price range forecast for polyethylene: 6800 - 7200, with a current volatility of 8.43% and a historical percentile of 5.8% (3 - year) [13]. - Hedging strategy for inventory management: For enterprises with high finished - product inventory, they can short plastic futures to lock in profits and sell call options to reduce costs [13]. - Hedging strategy for procurement management: For enterprises with low procurement inventory, they can buy plastic futures to lock in procurement costs and sell put options to reduce costs [13]. 3.2 This Week's Important Information and Next Week's Attention Events 3.2.1 This Week's Important Information - Bullish information: The market's concern about the US imposing a 100% tariff on China was alleviated by Trump's signal. A 500,000 - ton LLDPE full - density device of Yulong stopped for 5 days due to a fault [15]. - Bearish information: The risk - aversion sentiment in the financial market led to a continuous decline in crude oil prices [16]. 3.2.2 Next Week's Important Events to Follow - The decline of the plastic market slowed down on Wednesday and Thursday, and the downstream's willingness to buy at the bottom increased, leading to a rapid increase in trading volume [17]. 3.3 Disk Interpretation 3.3.1 Price, Volume, and Fund Interpretation - Unilateral trend and fund movement: In the context of the continuous decline of crude oil, PE prices followed the downward trend. This week, the position increased slightly, and the market's bearish sentiment was strong [22]. - Basis structure: During the decline this week, the spot price weakened following the disk, and the basis strengthened passively [24]. - Spread structure: The spread structure has not changed much recently, and the L1 - 5 spread shows a contango structure [26]. 3.4 Valuation and Profit Analysis - As PE prices continued to be weak, the production profits of all production lines were compressed. The coal - based production line with the best profit is on the verge of losses. PE devices are not sensitive to profit, so short - term losses do not usually cause unexpected shutdowns, resulting in a lack of strong cost support during the price decline [28]. 3.5 Supply - Demand and Inventory Deduction 3.5.1 Supply - Demand Balance Sheet Deduction - With the restart of devices and the commissioning of new production capacity, supply pressure will gradually emerge. After October, imports are expected to increase, further increasing the total PE supply. Although it is the traditional peak season for PE downstream, demand growth is expected to be lower than supply. In October, inventory is expected to change from destocking to stocking rapidly, and the supply - strong and demand - weak pattern will suppress PE prices [34]. 3.5.2 Supply - Side and Deduction - The current PE operating rate is 81.76% (- 2.19%). This week, the device maintenance volume increased slightly. ExxonMobil's 500,000 - ton LDPE device is in the trial - run stage. Overall, the return of maintenance devices and the commissioning of new production capacity in the fourth quarter will lead to continuous high supply pressure [38]. 3.5.3 Import - Export and Deduction - Import: The overseas PE supply - demand pattern is loose, and the price difference between the US and China has dropped to a historical low. It is expected that PE imports will increase from late October to November [41]. - Export: Enterprises' enthusiasm for expanding export channels is high this year, and PE exports have increased even in the off - season, but the overall volume is still small and has little impact on the PE supply - demand pattern [41]. 3.5.4 Demand - Side and Deduction - The average operating rate of PE downstream industries is 42.17% (+ 0.56%). The agricultural film operating rate increased significantly, but the growth is slower than in previous years. Other downstream demand is flat, so the demand - side support for PE is limited [44].
