1. Report Industry Investment Rating - Unilateral: Neutral; supply-side device maintenance and restart changes frequently, combined with new device production capacity release, supply may still be relatively loose; downstream demand overall start-up recovery supports propylene prices in the short term [3] - Inter-period: None - Inter-variety: None 2. Core Viewpoints - South Korea's petrochemical industry's naphtha cracking has the expectation of capacity reduction, and the propylene futures price rebounds under the boost of macro sentiment. South Korea's propylene capacity accounts for 6% of the global total capacity, and from January to July this year, China imported 863,000 tons of propylene from South Korea, accounting for 67.6% of the total imports, and 73.7% in 2024. South Korea's petrochemical capacity reduction may support overseas propylene prices [2] - From the perspective of supply and demand fundamentals, the main PDH devices of Shandong Zhenhua and Jinneng are under maintenance, and the PDH devices of Tianhong and Xintai are restarted, and the PDH start-up rate decreases month-on-month; later, Wanhua Penglai PDH has the expectation of shutdown, and Jilin Petrochemical's new capacity is expected to be released, and the supply may still be relatively loose. Pay attention to the device maintenance situation after late August. The downstream start-up rate has rebounded overall except for acrylic acid. Among them, the start-up rate of octanol has rebounded significantly, the start-up rate of PP has increased slightly, and the start-up rate of acrylic acid has decreased significantly. Later, the PP device of Jingbo and the acrylic acid device of Hongxin have the expectation of recovery. The short-term demand is supported, but the sustainability is questionable. Pay attention to the downstream stocking demand as the peak season approaches [2] - On the cost side, the crude oil price rebounds and fluctuates. Pay attention to macro trends such as geopolitical situations and the implementation of South Korea's cracking device capacity reduction policy [2] 3.

Report Industry Investment Rating - Unilateral: Neutral; no specific ratings for inter - period and cross - variety [3] Core Viewpoints - Propylene prices are expected to fluctuate weakly in the short term due to ample supply, insufficient downstream demand, and weak cost support. However, prices may be supported after late August due to potential supply - side maintenance and downstream demand restocking [3] Summary by Directory 1. Propylene Basis Structure - This section includes charts of the closing price of the propylene main contract, the East China basis of propylene, the North China basis of propylene, the 01 - 05 contract of propylene, the East China market price of propylene, and the Shandong market price of propylene [7][10][12] 2. Propylene Production Profit and Operating Rate - It involves charts of the difference between China's CFR propylene and Japan's CFR naphtha, propylene capacity utilization rate, PDH production gross profit of propylene, PDH capacity utilization rate of propylene, MTO production gross profit of propylene, methanol - to - olefins capacity utilization rate, naphtha cracking production gross profit of propylene, and the capacity utilization rate of the main crude oil refinery [16][25][27] 3.

Propylene Inventory - This section contains charts of propylene in - plant inventory and PP powder in - plant inventory [68]

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None; Inter - variety: None [3] Core View - Downstream demand support for propylene is limited, and propylene continues to fluctuate weakly. Shandong Zhenhua's main PDH unit and Xintai unit are under maintenance, briefly supporting a slight increase in Shandong spot prices. However, Wanhua's PO maintenance increases propylene supply in Yantai, and downstream resistance to high prices weakens the positive impact of maintenance, causing prices to fall from highs. In the future, Tianhong and Xintai's PDH units are expected to restart, and the new capacity of Jingbo's 280,000 - ton/year K - COT unit will be released, resulting in a relatively loose supply. Downstream start - up shows a mixed trend, with overall changes being small. Short - term demand support is limited, and attention should be paid to the restocking demand as the peak season approaches. The continuous weakening of crude oil on the cost side provides negative cost support [1][2] Summary by Directory 1. Propylene Basis Structure - Figures include propylene main contract closing price, East China basis, North China basis, 01 - 05 contract, East China market price, and Shandong market price [7][10][12] 2.
