Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None [3] Core View - The military conflict between Israel and Iran continues, the macro - atmosphere persists, and polyolefins are running strongly, but the impact of the sentiment side is narrowing. International oil prices and propane prices are running strongly, and the cost support for polyolefins is strengthening. The previously shut - down PE plants have resumed operation, and some plants are scheduled for maintenance, with overall high - level operation. PP maintenance plants have returned, resulting in greater supply - side pressure. The overall inventory level of upstream has a small reduction in the de - stocking range. The overall operating rates of downstream polyolefin industries have not changed much, and terminal enterprises have a small number of new orders, with cautious procurement [2] Summary According to the Directory 1. Polyolefin Basis Structure - The closing price of the L main contract is 7462 yuan/ton (+44), and the closing price of the PP main contract is 7274 yuan/ton (+60). The spot price of LL in North China is 7450 yuan/ton (+80), the spot price of LL in East China is 7470 yuan/ton (+50), and the spot price of PP in East China is 7280 yuan/ton (+30).

Report Industry Investment Rating - The unilateral strategy is neutral, and there is no recommendation for the inter - period strategy [3] Core View - The escalation of the geopolitical situation in the Middle East has led to a strong trend in crude oil prices, driving up polyolefins from the cost side. Propane prices are also strong, and the production profit of PDH - made PP remains in the red. The previously shut - down PE plants have resumed operation, and some plants are under planned maintenance, with overall high - level operation. The shut - down PP plants have returned, putting great pressure on the supply side. The overall inventory level of upstream has a small reduction. In the seasonal consumption off - season, downstream demand remains weak, mainly with terminal rigid - demand procurement. The agricultural film operation has bottomed out and rebounded but is still at a low level, and demand cannot drive the market [2] Summary by Directory I. Polyolefin Basis Structure - The closing price of the L main contract is 7418 yuan/ton (+101), and the closing price of the PP main contract is 7214 yuan/ton (+89).

Report Industry Investment Rating - The report gives a neutral rating for the unilateral strategy of polyolefins and no rating for the inter - period strategy [3] Core Viewpoints - The escalation of the geopolitical situation between Israel and Iran has led to a significant increase in international oil prices, strengthening the cost support for polyolefins [2] - PE's previous maintenance devices have resumed operation, and some devices are under planned maintenance, with overall high - level operation. PP's maintenance devices have returned, resulting in greater supply - side pressure, and the upstream inventory level has a small de - stocking amplitude [2] - It is the seasonal consumption off - season, and downstream demand remains weak, mainly for terminal rigid - demand procurement. The agricultural film operation rate has bottomed out and rebounded but is still at a low level, and demand is difficult to drive [2] - The production profit of PDH - made PP remains in the loss state. New maintenance of PDH devices in Shaoxing Sanyuan and Haitian Petrochemical, and the extended maintenance of Juzhengyuan have strengthened the cost support for PP [2] Summary According to Relevant Catalogs 1. Polyolefin Basis Structure - It includes the trends of plastic and polypropylene futures' main contracts, and the basis between LL/PP in East China and their main contracts [8][11] 2. Production Profit and Operation Rate - It covers the production profit of LL (crude - oil - made), PE operation rate, PE weekly output, PE maintenance loss, PP production profit (crude - oil - made and PDH - made), PP operation rate, PP weekly output, PP maintenance loss, and PDH - made PP capacity utilization rate [18][21][30] 3.

Report Investment Rating - There is no information about the industry investment rating provided in the report. Core Viewpoints - The imposition of tariffs by the US affects exports, and polyolefins are mainly in a weak consolidation state. Currently, the supply of PE remains at a high level, and the capacity utilization rate is expected to remain stable in the short term, with supply still under pressure. The capacity utilization rate of PP has increased slightly, and it is expected that the number of newly added maintenance enterprises will increase, resulting in a shrinking supply trend. The commissioning of the new Shandong Xinshengdai plant may be postponed. The propane price fluctuates significantly following the international crude oil price, and the production profit of PDH - made PP remains near the break - even point, with a fair cost - side support. The increase in the operating rate of downstream factories is limited, and the operating rate of agricultural films is expected to decline, gradually transitioning to the off - season. Affected by the tariff policy, the external demand for PP is expected to weaken. The inventory in the upstream and mid - stream links has been slightly reduced. [2] - For trading strategies, it is recommended to be cautiously bearish on plastics in the single - side trading, and there is no recommendation for inter - period trading.
