A decrease in crude oil prices could potentially reduce the production cost of propylene, but as a downstream petrochemical product, weak demand expectations might lead to downward pressure on prices, reflecting a slight bearish outlook. Benzene, with a rating of -0.5. As an upstream raw material, a decrease in crude oil prices reduces the cost pressure on benzene, but market concerns over weakening demand could drag down prices, indicating a slight bearish outlook. Diesel, with a rating of -1. A direct reduction in diesel production costs is expected due to the decrease in crude oil prices, and as a major downstream product, fuel oil and related varieties have already fallen in futures data, indicating potential price pressure, scoring moderate bearishness. Asphalt, with a rating of -1. A significant impact on the cost of asphalt from crude oil prices has been observed, with futures data showing that the contract for petroleum asphalt (contract number 2606) generally fell by 29 yuan, suggesting an increase in supply or insufficient demand, scoring general bearishness. Polyvinyl Chloride (PVC), with a rating of -0.5. A decrease in crude oil prices might alleviate the cost of PVC raw materials, but as a plastic product, prices are easily dragged down by demand, presenting potential downward risks, scoring slight bearishness. Gasoline, with a rating of -1. A decrease in crude oil prices reduces the refining cost of gasoline, and futures related varieties such as fuel oil have already fallen (contract number 2511 fell by 31 yuan), expecting retail prices to decline, scoring moderate bearishness. Ammonia, with a rating of 0. Ammonia is mainly influenced by the supply and demand of fertilizers, with a low correlation to crude oil, making its cost impact on crude oil relatively weak, and it remains neutral under stable demand. Crude Oil, with a rating of -1.5. WTI and Brent crude oil futures respectively fell by 1.3% and 1.5%, reflecting global oversupply or concerns about economic slowdowns, indicating significant short-term downward pressure, scoring a major bearish factor.
