Group 1 - The core viewpoint of the article highlights a bullish sentiment in the paraxylene (PX) market, driven by rising international oil prices and strong cost support [1] - Recent geopolitical tensions due to increased U.S. actions against oil tankers from a South American country have contributed to a rebound in oil prices from near four-year lows, further strengthening PX cost dynamics [1] - As of December 22, the CFR China PX price reached $893 per ton, marking a six-month high, with recent daily price increases exceeding $20 per ton [1] Group 2 - Anticipated maintenance of a heavy reforming unit in East China and upcoming maintenance schedules for various Asian PX facilities are expected to tighten supply [1] - The overall performance of PTA demand remains satisfactory, reinforcing expectations of a tight balance in the market, which enhances participants' confidence in future price movements [1]

Group 1: Investment Rating - No investment rating for the industry is provided in the report. Group 2: Core Views - Since the listing of propylene futures on July 22, the price of the main contract has shown an overall downward trend, affected by factors such as a loose fundamental situation, weakened cost support, and sluggish downstream demand [1][7]. - In 2026, it is necessary to focus on the production progress of the industrial chain, the PDH's phased adjustment of the supply - demand balance, the slow - down of PP growth but persistent pressure, and changes in the import - export pattern [1][2]. - The expected price range of propylene in 2026 is between 5,400 - 6,400 yuan/ton [3]. - Recommended strategies include unilateral interval operations and variety - based interval operations such as PP - PL and PL/PG (FEI/CP) [3]. Group 3: Summary by Directory Chapter 2: Market Review - After the listing of propylene futures on July 22, the main contract price declined from a high of 6,694 yuan/ton to a low of 5,715 yuan/ton, driven by factors such as a shift to a loose fundamental situation, weakened cost support, and sluggish downstream PP demand [7]. - There were also some phased disturbance factors during the decline, including the "anti - involution" policy expectation and unstable device operations [7][8]. - The propylene basis fluctuated between - 250 and 250 yuan/ton. The futures price was affected by fundamental over - supply pressure and the weakening of the PP end, while the spot price was more sensitive to device changes [10]. - The spot price difference between propylene and polypropylene (PP) fluctuated significantly, while the futures price difference had a relatively narrow range. The PP - PL spread showed different trends at different times due to factors such as device maintenance and new capacity addition [12]. Chapter 3: Core Focus Points - **3.1 Production Growth Slowdown**: From 2019 - 2025, the cumulative new propylene production capacity was about 45.87 million tons, with an average annual compound growth rate of 13%. As of now in 2025, the newly put - into - operation capacity is about 9.93 million tons, a 14.24% increase from 2024. In 2026, the planned new capacity is about 6 - 8 million tons, with a growth rate of 7.5% - 10%. The upstream - downstream integration trend is significant, and the actual supply - demand difference is also related to the start - up situation of upstream and downstream [14][16][18]. - **3.2 PDH's Phased Adjustment of Supply - Demand Balance**: PDH and refinery catalytic cracking devices have a greater impact on the propylene trading market. In 2025, the overall PDH operating rate was around 71%, with profit being the core driving factor. In 2026, low profit may become the norm, and some enterprises under greater operating pressure may arrange maintenance. Attention should be paid to enterprises with frequent start - stop operations and those that can significantly affect regional prices [20][21][23]. - **3.3 PP Growth Slowdown but Persistent Pressure**: The price of the propylene main contract is highly correlated with the PP futures price. In 2025, the total production capacity of polypropylene powder and granules reached 57.85 million tons, with a growth rate of 10.82%. In 2026, the planned new production capacity is 3.6 - 4.4 million tons, mainly concentrated in the second half of the year. Attention should be paid to the production rhythm, maintenance, and capacity clearance on the supply side, as well as domestic demand resilience and export increments on the demand side [25]. - **3.4 Import - Export Pattern Changes**: China is still a net importer of propylene. In January - October 2025, 1.83 million tons were imported, with 1.25 million tons from South Korea, accounting for 68.31% of the total imports. South Korea plans to restructure its petrochemical business, which may lead to a reduction in China's propylene imports from South Korea and have a positive impact on the domestic supply - demand and price [30][31][33]. Chapter 3 (Continued) - **3.1 Valuation Feedback**: PDH profit has room for repair. In the fourth quarter of 2025, the PDH profit space was significantly compressed. After the new year, some enterprises may arrange maintenance, and the PDH profit is expected to recover to some extent. The PP - PL spread is oscillating at a low level, and there may be some room for expansion in the future if PP device maintenance increases [36][38]. - **3.2 Supply - Demand Outlook**: From January - November 2025, the domestic propylene production was 55.35 million tons, a 13.82% year - on - year increase, with an average operating rate of 74%. In 2026, the production is expected to remain high, and the supply will remain loose. The demand side is affected by the over - supply pressure of PP and other downstream industries, and the over - supply pressure will increase with new capacity addition [40][42]. - **Shandong Market Balance**: The supply in the Shandong market is mainly affected by PDH and refinery catalytic cracking, with PDH having greater fluctuations. The demand is mainly affected by PP and PO. In 2026, attention should be paid to the operation of existing capacities on the supply side and the start - up of new downstream devices on the demand side [45][46].

Report Investment Rating No investment rating for the industry is provided in the report. Core Viewpoints - Crude oil's short - term core factor is geopolitics, with a pessimistic view on the cease - fire in the Russia - Ukraine conflict and an expectation of risk escalation in the Caribbean region. Aromatics (PX, PTA, BZ, EB) and methanol are short - term long - core varieties in the chemical industry [2][4]. - The supply - demand and macro drivers of crude oil are weak in the short term, but geopolitical factors may be the main driver in December. There are short - term long opportunities and mid - term short opportunities after a pulse - type upward movement [4]. Summary by Category Crude Oil - Logic: Supply - demand and macro drivers are weak. Short - term US high - frequency data is strong, and before a large - scale inventory build - up, the oversupply trading is difficult to restart. Geopolitical factors are the main driver in December, with a short - term long view and mid - term short opportunities after a pulse - type upward movement [3][4]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in short - term oscillation. The strategy is to wait and see in the hourly cycle [4]. Styrene - Logic: There is an unexpected inventory build - up during the seasonal de - stocking period, and there are still concerns about over - inventory. There are short - term fundamental contradictions and large mid - term differences. It is necessary to pay attention to the continuation of the gasoline - blending logic and future imports. Be cautious about the pulse - type upward movement of crude oil due to potential geopolitical escalation [7]. - Technical Analysis: The hourly - level is in short - term oscillation, and the structure is unclear. The strategy is to wait and see in the hourly and 15 - minute cycles after the stop - loss of long positions [8][9]. Rubber - Logic: There are no short - term contradictions. Tire demand has no significant increase, and the supply side is in the peak tapping season in Southeast Asia. The inventory in Qingdao is seasonally increasing. The market should be treated with an oscillation view [10]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in short - term oscillation. The strategy is to wait and see in the hourly cycle [10]. Synthetic Rubber - Logic: It is traded around butadiene. The butadiene inventory has reached a five - year high in the past two weeks, and the price is under pressure. Although the fundamental driver is downward, the low valuation lacks short - selling space. Be cautious about the pulse - type upward movement of crude oil due to potential geopolitical escalation [14]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in short - term oscillation. The strategy is to wait and see in the hourly cycle [14]. PX - Logic: The supply - demand is neutral to positive, but the current fundamentals cannot support an upward drive. The main trading logic is the expected market. Since November, the US aromatic gasoline - blending logic has led to a valuation repair. After the weakening of the gasoline - blending expectation last week, the cost - side crude oil and strong fundamentals in the chemical industry are likely to attract long - position funds. The long - position view is maintained [18]. - Technical Analysis: The hourly - level shows a short - term upward structure. The strategy is to hold long positions in the hourly level, with a stop - loss reference of 6700 [18]. PTA - Logic: The polyester has little pressure, but the current fundamentals cannot support an upward drive. The main trading logic is the expected market. Since November, the US aromatic gasoline - blending logic has led to a valuation repair. After the weakening of the gasoline - blending expectation last week, the cost - side crude oil and strong fundamentals in the chemical industry are likely to attract long - position funds. The long - position view is maintained [20]. - Technical Analysis: The hourly - level shows a short - term upward structure. The strategy is to hold long positions in the hourly level, with a stop - loss reference of 4620 [20]. PP - Logic: It still faces the pressure of olefin capacity to be put into production, with high supply pressure and weak downstream demand. The supply - demand drive is negative, and attention should be paid to the cost - side crude oil drive [23]. - Technical Analysis: The hourly - level is in short - term oscillation. The strategy is to wait and see in the hourly cycle [23]. Methanol - Logic: The over - expected maintenance in Iran has led to the shutdown of multiple methanol plants. With the temperature dropping in December, a full - scale shutdown is likely. After the market over - traded the expectation of insufficient gas restrictions, the market has room for upward correction. The port de - stocking rate is accelerating. The withdrawal of crowded short positions on the previous trading board brings a large upward space [24]. - Technical Analysis: The daily - level shows a mid - term downward structure and short - term oscillation. After testing the support without breaking it, the upward structure continues. The strategy is to hold long positions in the hourly cycle, with a stop - profit reference of 2100 [25][27]. PVC - Logic: High supply and high inventory continue. With the collapse of domestic real - estate demand, there is no hope for demand. The social inventory is still increasing, and there is no upward drive [28]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in short - term oscillation. The technical structure is unclear. The strategy is to wait and see in the hourly cycle [28]. Ethylene Glycol - Logic: Multiple MEG plants in Iran are under maintenance, but the domestic supply remains high with the resumption of maintenance and new capacity addition. Inventory build - up continues. Be vigilant about short - term geopolitical risks in crude oil [32]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in a downward structure. The upper short - term pressure is at 3920. The strategy is to wait and see in the single - side hourly cycle [32]. Plastic - Logic: The downstream demand recovers slowly, and the supply pressure from the upstream olefin capacity addition remains. The supply - demand is still weak. Be vigilant about short - term geopolitical risks in crude oil [33]. - Technical Analysis: The daily - level shows a mid - term downward structure, and the hourly - level is in a downward structure. The upper short - term pressure is at 6825. The strategy is to wait and see in the hourly cycle [33]. Soda Ash - Logic: The high - supply and high - inventory pattern continues, and the production cut in the downstream glass production line suppresses the demand for soda ash. Although the fundamental downward drive remains, the cost - performance of holding short positions unilaterally decreases [36]. - Technical Analysis: The hourly - level is in a downward structure. After a reduction in positions and a decline, the downward structure remains unchanged. The upper short - term pressure is at 1195. The remaining short positions in the hourly cycle should be held cautiously with a stop - profit at 1195 [36]. Caustic Soda - Logic: New capacity is put into production, and most plants have resumed operation after maintenance, resulting in high supply pressure. The alumina industry's losses are expanding, and the demand for caustic soda remains weak. There is no upward drive in supply - demand [39]. - Technical Analysis: The hourly - level is in a downward structure. After an increase in positions and a decline, the downward structure remains unchanged. The upper short - term pressure is at 2220. The strategy is to wait and see in the hourly cycle [39].
