聚烯烃季报：矛盾有限，聚烯烃价格重心下移

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Polyolefins, including polypropylene (PP) and polyethylene (PE), are in a downward - trending phase. Their price centers are expected to decline in the later period. The reason is that they are in a capacity - release cycle, with new devices coming into operation and high existing production loads. Meanwhile, Q4 may see an increase in imports, leading to large supply pressure. Although demand has entered the peak season, it fails to meet expectations and cannot digest the high production volume. As a result, the price center of polyolefins may continue to move down [3]. - In Q3, the polyolefin market had no major contradictions, but the supply - demand pattern was under pressure. New devices were put into production, and demand in the peak season was lower than expected, causing the price center to gradually decline. In Q4, the supply pressure will increase due to expected import growth, the cost - side crude oil outlook is pessimistic, and the oversupply pattern will continue to intensify, further pressuring prices [3][4]. 3. Summaries According to Relevant Catalogs 3.1 Market Review - Price, Basis, and Spread Trends: In July, after a brief rebound, polyolefin prices started to decline. In August and September, prices, especially for PP, weakened. The basis of PP was under pressure, and the 1 - 5 spread was at a low level. The basis of PE was stronger than that of PP and has been strengthening since August, but the absolute value was still low. The 1 - 5 spread of PE also weakened against the season [11][18]. - Spread Analysis: Before late August, the L - P spread was upward, but then turned downward as the demand for L also failed to meet expectations. The L - V01 and PP - V01 spreads fell in July and then recovered and stabilized in August. Methanol was statically weak, and MTO profits improved [33][34]. 3.2 Supply Review - Domestic Capacity Release: In 2025, multiple PP and PE production devices are planned to be put into production. In Q3, PP added 1.3 million tons of production capacity, and there are still 750,000 tons to be put into operation by the end of the year. PE added 900,000 tons of production capacity in Q3, and there are still 1.7 million tons to be put into operation, with slightly greater pressure than PP [39][40]. - Production - Side Profits: In Q3, the cost - side oil price center moved down. The profit of the oil - based production end was at the same level as the previous year. LPG supply pressure increased, and PDH profits were poor. With the arrival of the coal - using peak season, coal prices rebounded, CTO profits shrank but remained high, and inland MTO profits deteriorated [65]. - Domestic Production and Load: From January to August, the supply of PP and PE remained high. In Q3, PP devices operated stably with few maintenance cases, but parking increased in mid - to - late September due to weak demand. PE had more maintenance, especially in September, but the overall supply was still in surplus [72][78]. - Imports and Exports: From January to August, PP imports decreased by 9.76% year - on - year, exports increased by 29.01% year - on - year, and net imports decreased by 91.68% year - on - year. PE imports decreased by 0.84% year - on - year, exports decreased by 25.91% year - on - year, and net imports decreased by 2.66% year - on - year [89][90]. 3.3 Demand Review - PP Demand: In Q3, PP demand entered the seasonal peak season but did not meet expectations. Although industries such as agriculture, construction, packaging, and PP pipes showed some improvement in demand, the overall demand was still weaker than expected, increasing the downward pressure on PP prices [115]. - PE Demand: PE has a more obvious demand peak - season attribute, but similar to PP, the demand support was not strong. With the approach of the peak season for greenhouse film demand, production has recovered, but it was worse than the same period last year. The packaging film market has slightly improved, but the overall demand has not fully met expectations [133]. 3.4 Inventory Review - PP Inventory: Upstream production enterprises actively reduced inventory, and inventory mainly accumulated in the middle - link. Production enterprise inventory, port inventory, and trader inventory data showed the inventory transfer and accumulation situation [134][137]. - PE Inventory: PE inventory remained stable, and inventory accumulated in the middle - link during the off - season. With the increase in demand for greenhouse film and packaging film in August, social inventory decreased slightly [151].
