Report Industry Investment Rating - L, PP are rated neutral; L01 - L05 and PP01 - PP05 are recommended for reverse spreads; no recommendation for cross - variety trading [3] Core View - For PE, the supply side has seen a more - than - expected return due to the restart of many previously shut - down plants. The demand side has a slight improvement in pre - holiday stocking, but the demand follow - up is slow. The cost side is supported by rising international oil prices, yet the PE trend is still suppressed by the supply side [2] - For PP, the supply pressure remains high despite the decline in overall PP start - up rate. The demand side is in a seasonally improving period, but the recovery is slow. The cost side has a slight rebound in international oil prices. In the short term, PP demand improves but is limited by supply, and low profits restrict its downside [2] Summary by Directory Market News and Important Data - **Price and Basis**: L main contract closed at 7,142 yuan/ton (+37); PP main contract closed at 6,877 yuan/ton (+35). LL North China spot was 7,080 yuan/ton (+10), LL East China spot was 7,110 yuan/ton (+0), PP East China spot was 6,730 yuan/ton (+0).

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]

Group 1: Report Information - Report Name: Polyolefin Daily Report [1] - Date: August 14, 2025 [2] - Research Team: Energy and Chemical Research Team [4] Group 2: Market Quotes - Futures Market Quotes: - Plastic 2601: Opened at 7390 yuan/ton, closed at 7381 yuan/ton, down 2 yuan/ton (-0.03%), with a trading volume of 283252 lots and an increase of 18065 lots in open interest [5] - Plastic 2605: Opened at 7390 yuan/ton, closed at 7386 yuan/ton, down 4 yuan/ton (-0.05%), with a trading volume of 15253 lots and an increase of 754 lots in open interest [5] - Plastic 2509: Opened at 7320 yuan/ton, closed at 7313 yuan/ton, down 15 yuan/ton (-0.20%), with a trading volume of 212562 lots and a decrease of 20560 lots in open interest [5] - PP2601: Opened at 7128 yuan/ton, closed at 7107 yuan/ton, down 19 yuan/ton (-0.27%), with a trading volume of 329308 lots and an increase of 24541 lots in open interest [5] - PP2605: Opened at 7104 yuan/ton, closed at 7099 yuan/ton, down 18 yuan/ton (-0.25%), with a trading volume of 19306 lots and an increase of 4910 lots in open interest [5] - PP2509: Opened at 7085 yuan/ton, closed at 7081 yuan/ton, down 17 yuan/ton (-0.24%), with a trading volume of 141836 lots and a decrease of 23955 lots in open interest [5] Group 3: Market Review and Outlook - Market Performance: L2509 opened lower, fluctuated up and down during the session, and finally closed at 7313 yuan/ton, down 15 yuan/ton (-0.2%). The trading volume was 160,000 lots, and the open interest decreased by 20,560 to 212,562 lots. The main contract of PP switched to 2601, closing at 7107 yuan/ton, down 19 yuan/ton (-0.27%), with an increase of 24,500 lots in open interest to 329,300 lots [6] - Supply: The operating load of upstream plants continued to increase. Although the maintenance loss of PP was still at a high level, as the previously shut - down plants were gradually restarted and there were not many newly added maintenance plants, the impact of maintenance decreased. With the approaching of the 900,000 - ton/year capacity expansion plan of Ningbo Daxie Phase II, the incremental pressure on the supply side gradually emerged. For PE, the commissioning of Jilin Petrochemical at the end of July further expanded the production capacity base, and attention was paid to the new capacity addition of ExxonMobil Huizhou in August [6] - Demand: Downstream factories were still affected by the off - season. Coupled with the pressure of losses, the willingness to stock up was low. It was expected that the demand would gradually get out of the off - season in the second half of the month, but currently, downstream enterprises mostly maintained a low - inventory strategy [6] - Cost: The coal price was likely to rise due to coal mine production inspections and the peak summer coal - using season. The oil price might fall again due to the negative impact of OPEC+ production increase and the under - expected performance in the peak season [6] - Outlook: The loose fundamental pattern would continue to restrict the upward space. With the continuous release of new production capacity and the expected stocking demand driven by the "Golden September" peak season in the second half of the month, the polyolefin price might show a trend of bottom - building and then rebounding [6] Group 4: Industry News - Inventory: On August 13, 2025, the inventory level of major producers was 795,000 tons, a decrease of 20,000 tons (-2.45%) from the previous working day. The inventory at the same time last year was 815,000 tons [7] - PE Market: The PE market prices showed mixed trends. The linear futures opened lower and fluctuated, and the market trading atmosphere changed little. Traders reported prices with narrow fluctuations. The LDPE prices were firm, and downstream buyers purchased according to orders. The LLDPE prices in North China were 7200 - 7420 yuan/ton, in East China were 7240 - 7700 yuan/ton, and in South China were 7380 - 7700 yuan/ton [7] Group 5: Data Overview - Propylene Market: The mainstream price of propylene in the Shandong market was temporarily referred to as 6500 - 6530 yuan/ton. The profit margins of downstream products were compressed, and the willingness to accept propylene prices decreased. The demand support for propylene weakened. Production enterprises mostly offered small discounts to promote transactions, and the overall market trading atmosphere was average [13] - PP Market: The PP market was mainly adjusted narrowly. The mainstream prices of North China drawn wire were 6930 - 7090 yuan/ton, in East China were 7000 - 7140 yuan/ton, and in South China were 6950 - 7150 yuan/ton [13]

Report Information - Report Name: Polyolefin Daily Report [1] - Date: August 7, 2025 [2] Industry Investment Rating - Not provided Core Viewpoints - The futures market opened higher and fluctuated upwards, boosting market sentiment. Spot prices fluctuated slightly, and downstream buyers replenished stocks according to orders. However, the supply pressure continued, and new PE and PP production facilities were planned to be put into operation in the third quarter. The demand was weak and needed improvement, and the downstream operating load remained low overall. It was expected that the demand would gradually emerge from the off - season in the second half of the month, but the downstream enterprises mainly maintained a low - inventory strategy, and the driving force for active replenishment was limited. The policy - driven market led the polyolefins to follow, but the loose fundamental pattern would continue to restrict their upward space. After the digestion of the anti - involution sentiment, the polyolefins would return to a weak and volatile operation [6] Summary by Directory 1. Market Review and Outlook - **Futures Market**: The L2509 contract of linear low - density polyethylene (LLDPE) opened higher, fluctuated upwards during the session, and finally closed at 7,321 yuan/ton, up 33 yuan/ton (0.45%). The trading volume was 167,000 lots, and the open interest decreased by 10,020 to 291,496 lots. The PP main contract closed at 7,078 yuan/ton, up 12 yuan (0.17%), and the open interest decreased by 7,127 to 251,400 lots [6] - **Supply**: In the third quarter, new PE production facilities of Jilin Petrochemical, ExxonMobil Huizhou, and Guangxi Petrochemical were planned to be put into operation. The second - phase project of Ningbo Daxie with a total annual production capacity of 900,000 tons was expected to be launched, which would have a significant impact on the supply side [6] - **Demand**: The downstream operating load remained low overall. Although the operating rate of the agricultural film industry rebounded from a low level, the demand followed up slowly. The orders in the construction field were mediocre, and the operating rates of the pipe and plastic weaving industries were at historical lows in the same period. The demand for daily - use injection - molded products increased slightly month - on - month [6] 2. Industry News - **Inventory**: On August 6, 2025, the inventory level of major producers was 785,000 tons, a decrease of 20,000 tons (2.48%) from the previous working day. The inventory in the same period last year was 810,000 tons [7] - **PE Market**: The PE market prices partially increased.

As of the 12 - o'clock closing, the reference price was 6,250 - 6,270 yuan/ton, an increase of 85 yuan/ton from the previous day. The temporary shutdown of some supply facilities boosted the operators' sentiment, and enterprises mainly raised their offers. The downstream followed up actively, the premium range of actual orders expanded, and the trading center shifted significantly upwards [7] - **PP Market**: The PP market was stable with a slight upward trend, and some prices increased by 20 - 30 yuan/ton. The mainstream prices of drawn PP in North China were in the range of 6,940 - 7,080 yuan/ton, in East China 7,000 - 7,130 yuan/ton, and in South China 6,960 - 7,150 yuan/ton [7] 3.

Report Industry Investment Rating - Not provided in the report Core Viewpoints - Polyolefin futures rebounded slightly. The spot prices of linear LL and拉丝 PP from Sinopec and PetroChina remained stable. The market showed a divergence this week after a rebound last week, and the spot market of polyolefins is still mainly driven by supply and demand. Summer maintenance is in balance, and attention should be paid to the process of fundamental repair. Recently, supply and demand tend to gradually digest the inventory accumulated in the second quarter [2] Summary by Relevant Catalogs Futures Market - **LL Futures**: The previous day's closing prices for January, May, and September contracts were 7400, 7395, and 7335 yuan/ton respectively, with declines of -104, -98, and -121 yuan/ton and drops of -1.39%, -1.31%, and -1.62% respectively.
