1. Market News and Key Data - Propylene: The closing price of the main propylene contract was 6,415 yuan/ton (+10), the spot price in East China was 6,575 yuan/ton (+0), and the spot price in North China was 6,630 yuan/ton (-5). The basis in East China was 160 yuan/ton (-10), and the basis in North China was 215 yuan/ton (-15). The propylene operating rate was 75% (-1%), the difference between China's CFR propylene and Japan's CFR naphtha was 190 US dollars/ton (-4), the difference between propylene CFR and 1.2 propane CFR was 89 US dollars/ton (-10), the import profit was -159 yuan/ton (+25), and the in-plant inventory was 39,110 tons (-1,210) [1]. - Propylene downstream: The operating rate of PP powder was 41% (+1.22%), and the production profit was -260 yuan/ton (+5); the operating rate of propylene oxide was 73% (-1%), and the production profit was -120 yuan/ton (-62); the operating rate of n-butanol was 87% (-2%), and the production profit was -123 yuan/ton (+3); the operating rate of octanol was 94% (+2%), and the production profit was 154 yuan/ton (-47); the operating rate of acrylic acid was 69% (-1%), and the production profit was 157 yuan/ton (+0); the operating rate of acrylonitrile was 74% (+1%), and the production profit was -682 yuan/ton (+30); the operating rate of phenol-ketone was 76% (-2%), and the production profit was -539 yuan/ton (+0) [1]. 2. Market Analysis Supply side - Regarding the main PDH units, Hebei Haiwei's 500,000-ton unit was under maintenance, Wanhua Penglai had a restart expectation recently, Shandong Zhenhua's PDH restart was postponed, and Qingdao Jinneng's maintenance continued. The PDH operating rate decreased month-on-month, and the external supply of propylene tightened, which supported the price in the short term. Attention should be paid to the continuous maintenance of the units [2]. Demand side - The operating rates of propylene downstream industries showed a mixed trend. The operating rate of PP increased month-on-month, mainly due to the support from the demand for PP downstream packaging films, injection molding, etc.; the operating rate of octanol continued to rise significantly, while the operating rates of n-butanol, PO, and phenol-ketone declined significantly. The downstream demand showed a slight recovery in the short term, but the overall profit of downstream products was average. The increase in the propylene spot price compressed the downstream profit, and the purchasing enthusiasm of some downstream industries weakened, suppressing the upward space of propylene. Attention should be paid to the stocking demand as the "Golden September and Silver October" peak season approaches [2]. Cost side - OPEC+ has a production increase expectation, and the crude oil price may decline; the Saudi CP propane price in September was 520 US dollars/ton, unchanged month-on-month, and the landed price of the overseas propane swap also has a decline expectation [2]. 3. Strategy - Unilateral: Neutral; The expected tightening of PDH propylene supply supports the price, but the downstream profit is under pressure and may lack follow-up strength [2]. - Inter - period: None [2]. - Inter - variety: None [2]. 4.
