Report Industry Investment Rating - Not provided Core Viewpoints - Plastic supply and demand pattern improves limitedly, but there are still expectations for the chemical industry to counter the involution. The upstream petrochemical inventory is low, and the basis has been repaired. Due to the long Spring Festival holiday, the risk of unilateral positions is high, so it is recommended to hold no positions for the holiday. Since there is new plastic production capacity put into operation recently, the operating rate is higher than that of PP, and the concentrated demand for plastic film has not started yet, it is advisable to hold a light - position short L - PP spread [1]. Summary by Relevant Catalogs Market Analysis - On February 12, the number of overhauled devices changed little, and the plastic operating rate remained at around 92%, which is at a moderately high level. As of the week of February 6, the downstream operating rate of PE decreased by 4.03 percentage points to 33.73% week - on - week. Entering the Spring Festival holiday, orders and raw material inventory of agricultural film continued to decrease, and packaging film orders also decreased. The overall downstream operating rate of PE declined seasonally. Petrochemical de - stocking in February was acceptable, and the current petrochemical inventory is at a low level in recent years. The cost of crude oil rebounded due to market concerns about military conflicts between the US and Iran. New plastic production capacities were put into operation in January 2026. The plastic operating rate increased slightly recently. The concentrated demand for plastic film has not started yet, and it is expected that the downstream operating rate will continue to decline [1]. Futures and Spot Market Quotes - **Futures**: The plastic 2605 contract opened higher, then decreased in position and oscillated downward. The lowest price was 6732 yuan/ton, the highest was 6834 yuan/ton, and it finally closed at 6734 yuan/ton, above the 60 - day moving average, with a decline of 0.72%.

Report Industry Investment Rating - Not provided Core Viewpoint of the Report - Previously, the increase in costs and the peak season of downstream demand drove the price of plastics to rebound. However, with the overall supply - demand pattern remaining unchanged, it is expected that plastics will mainly show a weak and volatile trend in the near future [1] Summary by Relevant Catalogs Market Analysis - On November 19, the overhauled units such as full - density units of Ningxia Baofeng restarted, and the plastic operating rate rose to around 89%, currently at a neutral level. As of the week of November 14, the downstream operating rate of PE decreased by 0.36 percentage points to 44.49% week - on - week. The agricultural film is still in the peak season, with stable orders and raw material inventory, but the orders for packaging film continued to decline slightly. The overall downstream operating rate of PE is still at a relatively low level in the same period in recent years. Petrochemical inventory reduction slowed down, and the current petrochemical inventory is at a moderately high level in the same period in recent years. The cost - end crude oil price rebounded after a decline, but the supply surplus pattern limited its increase. New production capacities were put into operation, and downstream enterprises had insufficient purchasing willingness. Traders were cautious about the future market and actively sold goods at reduced prices. The anti - involution policy has not been implemented yet [1] Futures and Spot Market Conditions - **Futures**: The plastic 2601 contract decreased in positions and fluctuated upwards, with a minimum price of 6781 yuan/ton, a maximum price of 6838 yuan/ton, and finally closed at 6833 yuan/ton, below the 60 - day moving average, with a gain of 0.22%.

The overall downstream operating rate of PE is still at a relatively low level in the same period in recent years. Petrochemicals are normalizing inventory, and the current petrochemical inventory is at a neutral level in the same period in recent years. In terms of cost, OPEC adjusted the global oil supply in the third quarter of 2025 from a shortage of 400,000 barrels per day to a surplus of 500,000 barrels per day, and the pattern of oversupply in the crude oil market has become more widely recognized, leading to a decline in crude oil prices. In terms of supply, ExxonMobil (Huizhou) with a new production capacity of 500,000 tons per year of LDPE started trial operation, and PetroChina Guangxi Petrochemical with a production capacity of 800,000 tons per year was recently put into production. The plastics operating rate has slightly decreased. The agricultural film is in the peak season, with orders gradually accumulating, but the peak season is not as good as expected. The price of agricultural film is stable. After the National Day, the stocking demand decreased periodically, the downstream operating rate began to decline, and the purchasing willingness of downstream enterprises was insufficient. Traders are cautious about the future market and generally reduce prices to actively sell goods. There is still no actual policy for anti - involution in the plastics industry. Of course, anti - involution and the elimination of old devices to solve the problem of overcapacity in the petrochemical industry are still macro - policies that will affect the subsequent market [1] Futures and Spot Market Conditions Futures - The plastics 2601 contract fluctuated with a reduction in positions. The lowest price was 6,756 yuan per ton, the highest price was 6,820 yuan per ton, and it finally closed at 6,818 yuan per ton, below the 60 - day moving average, with a gain of 0.50%.

Report Industry Investment Rating - No investment rating provided in the report Core Viewpoints - The PE market is under pressure due to factors such as increased inventory, insufficient demand, new device production, and weakened cost support from falling oil prices. Future focus should be on cost - side disturbances [2] - The PP market is affected by weakening costs (falling oil and propane prices). Supply is increasing while demand fails to meet expectations, resulting in a loose supply - demand situation. Short - term pressure on the PP market is high, and attention should be paid to the impact on propane supply and marginal device operations [2] - For trading strategies, it is recommended to take a wait - and - see approach for both L and PP in the single - side trading. For cross - period trading, conduct reverse spreads for L01 - L05 and PP01 - PP05. For cross - variety trading, shrink the spread of PP01 - 3MA01 when it is high [3] Summaries by Directory Market News and Key Data - **Price and Basis**: The closing price of the L main contract is 6929 yuan/ton (+19), and the PP main contract is 6618 yuan/ton (+23). LL and PP spot prices and basis have different changes [1] - **Upstream Supply**: PE operating rate is 81.8% (-2.2%), and PP operating rate is 78.2% (+0.5%) [1] - **Production Profit**: PE oil - based production profit is 434.2 yuan/ton (-18.2), PP oil - based production profit is - 135.8 yuan/ton (-18.2), and PDH - based PP production profit is 64.9 yuan/ton (-109.7) [1] - **Imports and Exports**: LL import profit is - 165.0 yuan/ton (-56.8), PP import profit is - 537.9 yuan/ton (+16.1), and PP export profit is 26.9 dollars/ton (+3.3) [1] - **Downstream Demand**: PE downstream agricultural film operating rate is 42.9% (+7.3%), PE downstream packaging film operating rate is 52.2% (-0.7%), PP downstream plastic weaving operating rate is 44.3% (+0.0%), and PP downstream BOPP film operating rate is 61.2% (+0.5%) [1] Market Analysis - **PE**: After the holiday, inventory of major plastic producers has increased significantly. Demand is insufficient, and new device production and falling oil prices have weakened cost support. Supply is expected to increase, demand is lower than expected, and cost support is weakening. Future focus should be on cost - side disturbances [2] - **PP**: The recent weakening of the PP market is due to falling oil and propane prices. Supply is increasing, demand fails to meet expectations, and cost support is weak. Short - term pressure on the PP market is high, and attention should be paid to propane supply and marginal device operations [2] Strategy - **Single - side**: Wait and see for both L and PP [3] - **Cross - period**: Reverse spreads for L01 - L05 and PP01 - PP05 [3] - **Cross - variety**: Shrink the spread of PP01 - 3MA01 when it is high [3]
