Investment Rating - The report does not explicitly state an investment rating for the petrochemical industry [1]. Core Insights - The report highlights that the reduction in production of polyester filament supports the upward movement of product prices [1]. - Domestic and international refining project price differentials are tracked, with domestic key refining project price differential at 2474.39 CNY/ton, a decrease of 21.68 CNY/ton (-0.87%) week-on-week, while the international price differential is at 1105.24 CNY/ton, down by 57.47 CNY/ton (-4.94%) [2][3]. - Brent crude oil's weekly average price is reported at 64.50 USD/barrel, reflecting a week-on-week increase of 4.69% [2].

Initially, oil prices rose due to these tensions, but later eased as the situation in Iran stabilized and Venezuelan oil exports resumed [2][15]. - Domestic refined oil prices have shown a slight decline, with diesel, gasoline, and aviation kerosene averaging 6334.57 CNY (-70.71), 7526.14 CNY (-25.43), and 5246.79 CNY (-11.79) per ton respectively [15]. Chemical Sector - The chemical products' prices have generally increased due to strong cost support.

Polyester & Nylon Sector - In the polyester segment, cost support remains strong, but weak demand in the textile sector has led to a slight increase in PX prices. The overall operating rate has decreased due to maintenance and production cuts in filament plants, resulting in price increases driven by supply-side support [2][43].
