1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The supply and demand of propylene are still supported, but attention should be paid to the cost - side fluctuations. The supply of propylene is expected to increase slightly. On the demand side, the downstream rigid demand continues to support, but the demand follow - up may be limited after the profit is compressed. The cost - side fluctuations are intensifying, and the future main drivers lie in the trends of crude oil and propane on the cost side, the maintenance dynamics of major PDH plants, and the start - up follow - up of downstream demand under cost pressure [1][2] - For trading strategies, it is recommended to wait and see in the single - side trading. There is no suggestion for inter - period and inter - variety trading [3] 3. Summary According to Relevant Catalogs I. Propylene Basis Structure - The report presents figures on the closing price of the propylene main contract, the East China basis of propylene, the Shandong basis of propylene, the spread between the 03 - 04 contracts of propylene, the spread between the PL03 - 05 contracts, and the market prices of propylene in East China, Shandong, and South China [6][8][15] II. Propylene Production Profit and Capacity Utilization - Figures include the difference between propylene CFR in China and naphtha CFR in Japan, propylene capacity utilization, PDH production gross profit of propylene, PDH capacity utilization of propylene, MTO production gross profit of propylene, methanol - to - olefins capacity utilization, propylene naphtha cracking production gross profit, crude oil refinery capacity utilization, the difference between South Korea FOB and China CFR, and propylene import profit [21][23][29] III. Propylene Downstream Profit and Capacity Utilization - The report shows figures on the production profit and capacity utilization of PP powder, propylene oxide, n - butanol, octanol, acrylic acid, acrylonitrile, and phenol - acetone [41][42][49] IV. Propylene Inventory - Figures on propylene in - plant inventory and PP powder in - plant inventory are presented [66]

1. Report Industry Investment Rating - Unilateral: Neutral; continue to monitor upstream PDH maintenance dynamics and changes in propane prices on the cost side [3] 2. Core View of the Report - The overall supply of propylene is tightening, with PDH device parking information continuously being released. The supply pressure in the propylene market is expected to be alleviated, and the market price will fluctuate following the cost side in the short term. The downstream demand has rigid support, but the demand may be limited after the profit is compressed. The international oil price has risen slightly, and the propane price is relatively strong [2] 3.

The PDH device parking information is continuously released, and the operating rate has declined significantly. The supply pressure in the propylene market is expected to be alleviated [2] - Demand side: The downstream has rigid support, but the demand may be limited after the profit is compressed. The PP powder operating rate has declined significantly, the propylene oxide price has risen and then fallen, and the n-butanol and octanol have strong support for propylene [2] - Cost side: The international oil price has risen slightly, the propane price is relatively strong, and the propylene market price will fluctuate following the cost side in the short term [2] 3.3 Strategy - Unilateral: Neutral; continue to monitor upstream PDH maintenance dynamics and changes in propane prices on the cost side [3] - Inter-period: None [3] - Cross-variety: None [3] 3.4 Propylene Basis Structure - Relevant figures include the closing price of the main propylene contract, the basis in East China and Shandong, the spread between contracts 03-04, the spread between PL03-05 contracts, and the market prices in East China, Shandong, and South China [6][8][17][18] 3.5 Propylene Production Profit and Operating Rate - Relevant figures include the difference between China's CFR propylene and Japan's CFR naphtha, propylene capacity utilization rate, PDH production gross profit and capacity utilization rate, MTO production gross profit, methanol-to-olefin capacity utilization rate, naphtha cracking production gross profit, crude oil main refinery capacity utilization rate, the difference between South Korea's FOB and China's CFR, and propylene import profit [22][25][30][33][34] 3.6 Propylene Downstream Profit and Operating Rate - Relevant figures include the production profit and operating rate of PP powder, propylene oxide, n-butanol, octanol, acrylic acid, acrylonitrile, and phenol-ketone [41][42][49][55][56][59][63] 3.7 Propylene Inventory - Relevant figures include propylene in-plant inventory and PP powder in-plant inventory [68]
