Report Industry Investment Rating No relevant content provided. Core Views of the Report - The propylene market in Shandong has shifted from tight supply before 2016 to near - balance or even oversupply currently due to the high - speed commissioning of propylene plants, especially PDH and naphtha cracking plants [4][12][28]. - After the listing of propylene futures, the market mainly trades on strong macro - policy expectations. The "anti - involution" policy is expected to promote the rectification and elimination of old - fashioned plants, which may reduce propylene supply and have a positive impact, but the extent remains to be tracked [14]. - In the short term, the propylene market shows a weak consolidation. Supply pressure persists with expected increases in propylene circulation due to plant restarts and new capacity releases. Demand has some short - term support but may not be sustainable during the off - season. Cost support from rising oil prices is offset by supply - demand pressures, resulting in a downward - pressured price trend [14]. Summary by Directory 1. Research Purpose - Explore the impact of propylene futures listing on the industry and understand the supply - demand situation of the propylene market in Shandong [10][11]. 2. Research Conclusion - **Supply - Demand Pattern**: Shandong's propylene production capacity exceeds 15 million tons, accounting for 21% of the national total, and the external sales volume accounts for 39%. It has changed from a supply - tight to a near - balanced or oversupplied market. There is a demand gap of nearly 600,000 tons, and it is a major propylene - importing province. Propylene flows in from the Northeast, Northwest, North, and Central China and flows out to East China [4][12][25]. - **Trading Mode**: Shandong is the national price benchmark for propylene, with earlier spot quotations. Contract sales in Shandong are less than 50%. Contracts are usually signed annually and settled monthly, while spot sales are full - payment locked - price. The flow of goods is determined by price differences, freight, and demand [4][12]. - **Cost - Profit**: The propane consumption of PDH plants is between 1.14 - 1.2, and the theoretical processing cost is between 1200 - 1500 yuan. The full cost of PDH - produced propylene is around 6100 - 6300 yuan/ton. Freight varies by transportation mode [4][15]. - **Inventory**: Inventory varies among enterprises. PDH enterprises generally have larger storage capacity and longer storage periods. During the research, enterprises reported low inventory and no obvious inventory pressure [4][15]. 3. Core Logic and Future Outlook - After the listing of propylene futures, the market is influenced by macro - policy expectations. The "anti - involution" policy may reduce supply, but the impact needs further observation. Currently, the market is in weak consolidation. Supply pressure exists due to plant restarts and new capacity, demand has short - term support but limited sustainability, and cost support is offset by supply - demand pressures [14]. 4. Specific Situations of Research Enterprises - **Enterprise A**: Total propylene capacity is 70,000 tons/year, using catalytic cracking. All products are sold externally. Current external sales are about 270 tons/day. The enterprise believes the market is oversupplied and focuses on PDH operations [15][16]. - **Enterprise B**: Total capacity is 355,000 tons/year, with 105,000 tons from catalytic cracking and 250,000 tons from PDH. One of the two gas - fractionation units is operating, with an output of about 75 tons/day. The PDH unit has been shut down for over three months [17]. - **Enterprise C**: Total capacity is 420,000 tons/year, with a 70% load on the mixed - alkane dehydrogenation unit. By - product hydrogen is sold externally. The acrylic acid unit is operating, and the propylene oxide unit is shut down due to profit issues [20]. - **Enterprise D**: Total capacity is 380,000 tons/year, with 80,000 tons from catalytic cracking and 300,000 tons from PDH. Only the gas - fractionation unit is operating, with an output of about 200 tons/day. The PDH unit is shut down [22]. - **Enterprise E**: Total capacity is 600,000 tons/year, using PDH. The PDH unit is operating at 90% load. The enterprise has a low - inventory strategy and is bearish on the market [24]. 5. Analysis of the Supply - Demand Pattern of Shandong Propylene - Shandong is a major propylene production and sales area, with a production capacity exceeding 15 million tons, accounting for 21% of the national total and an external sales volume accounting for 39%. There are regional differences within Shandong. There is a demand gap of nearly 600,000 tons, and the market has shifted from tight supply to near - balance or oversupply [25][27][28].

Report Industry Investment Rating - Unilateral: Neutral - Inter - period: PL01 - 02 inter - period reverse spread - Inter - variety: None [3] Core Viewpoints - The supply of propylene is expected to increase, with the restart of Tianjin Bohua's PDH unit in early August and the expected release of new production capacity. The demand has staged support due to the restart of some polypropylene and octanol plants, but its sustainability is questionable during the traditional off - season. The rebound in oil prices provides short - term cost support, but prices are mainly under pressure due to supply - demand imbalances [1][2] Summary by Directory Propylene Basis Structure - Propylene prices are in a low - level weak oscillation, showing a negative basis pattern [14] Propylene Monthly Output - In July, China's propylene plant output reached 5.1084 million tons, a month - on - month increase of 123,400 tons (2.5%) and a year - on - year increase of 13.0%. The output remains at a high level in the same period [22] Propylene Production Profit and Operating Rate - The profits of propylene production by different processes decreased month - on - month. The production profit of PDH - made propylene was in the red, and the loss of methanol - to - propylene profitability deepened. In July, the overall propylene capacity utilization rate was 71.6%, with a narrow month - on - month fluctuation [24] Propylene Outer - Market Spread and Import - Export - In June, China's propylene imports increased month - on - month, driven by imports from Japan, South Korea, and increased supply from Southeast Asia. Japan and South Korea are still the traditional major import sources. In June, China's propylene imports were 253,600 tons, a month - on - month increase of 28%. From January to June 2025, the cumulative imports were 1.0669 million tons [39] Propylene Downstream Operating Rate and Downstream Profit - The overall downstream operating rate increased limitedly. End - users mainly purchased at low prices, and demand resilience was still insufficient. The restart of some polypropylene and octanol plants provided staged demand support, but its sustainability is questionable during the traditional off - season. In terms of downstream profits, the profit of the propylene oxide industry rebounded significantly, while the profit of the n - butanol industry decreased month - on - month [53] Propylene Inventory - Propylene inventory in factories continued to rise, being higher year - on - year. The inventory of PP powder, the main downstream consumer, declined from a high level [75]
