Report Overview - The report is a weekly report on polyolefins by Guotai Junan Futures, covering plastics and polypropylene, including price, supply, demand, inventory, and other aspects [1] Plastics Section Core Viewpoint - The price of plastics is under pressure due to ample supply and weak demand. The market is expected to remain in a pattern of increasing supply and decreasing demand before the Spring Festival, with prices under pressure. The recommended strategy is to short on rebounds [5] Price & Spread - The spot price increase is limited following the futures price rebound, leading to a weaker basis and a stronger 5 - 9 month spread. The import window is repaired, and the non - standard price difference is at a relatively high level [5][14][15] Supply - The total effective production capacity in 2025 increased by 16%, with domestic production increasing by 18%. The supply is ample due to low maintenance in Q4 and some restarts during holidays. Some standard products are being converted to non - standard products, and the import volume may remain high at the beginning of 2026 [5] Demand & Inventory - The demand for agricultural films is in a seasonal off - peak, and the demand for packaging films is short - term and limited. The overall downstream demand is expected to decline. The inventory removal is not smooth, and the social inventory removal is slowing down [5] Polypropylene Section Core Viewpoint - The polypropylene price is under pressure in the off - season. The supply may have marginal changes if PDH plants shut down as expected. The market is also likely to face a pattern of increasing supply and decreasing demand in Q4, with a pessimistic outlook [91] Price & Spread - The basis is weak and volatile, and the month spread is oscillating. The import window is approaching closure, and the export profit to Southeast Asia has limited increase [91][101][105] Supply - The total effective production capacity increased by 12.7% in 2025, with an estimated annual output increase of 16.7%. The planned maintenance at the end of the year is decreasing, but there is an expectation of PDH plant shutdowns in January. The import and export volumes are expected to remain at a basic level [91] Demand & Inventory - The downstream start - up is temporarily stable, but the orders for some industries are seasonally weakening. The inventory removal is not smooth, and the inventory is concentrated in the middle stream, with a higher year - on - year level [91] Investment Strategy Plastics - Single - side: Oscillate weakly, short on rebounds [5] - Inter - period: Not recommended for now [5] - Inter - variety: Not recommended for now [5] Polypropylene - Single - side: Oscillate weakly, short on rebounds [91] - Inter - period: Not recommended for now [91] - Inter - variety: Not recommended for now [91]

1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core View of the Report - The prices of various energy and chemical commodities are expected to fluctuate. Crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefins, and polyvinyl chloride are all forecasted to maintain an oscillatory trend [1][2]. - The uncertainty in the Middle - East geopolitical situation and the US military strikes in Nigeria may impact the oil market. The increase in US oil inventories and the decrease in refinery processing volume also affect the oil price trend [1]. - The supply and demand fundamentals of different energy and chemical products vary. For example, low - sulfur fuel oil supply is sufficient, while high - sulfur fuel oil has some support; asphalt supply and demand are in a state of short - term stability and long - term uncertainty [2]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Monday, oil prices rose. WTI February contract closed up $1.34 to $58.08 per barrel, a 2.36% increase; Brent February contract closed up $1.30 to $61.94 per barrel, a 2.14% increase. SC2602 night - session closed at 436.9 yuan/barrel, up 1.3 yuan/barrel, a 0.3% increase. Geopolitical uncertainties in the Middle East and military strikes in Nigeria raised concerns about supply, but the increase in US inventories and the decrease in refinery processing volume also had an impact. With the New Year's Day holiday approaching, the market trading was light, and oil prices were expected to continue to fluctuate [1]. - **Fuel Oil**: On Monday, the main fuel oil contracts on the Shanghai Futures Exchange declined. The low - sulfur fuel oil market structure remained stable, and high - sulfur fuel oil had some support. Singapore was expected to receive more low - sulfur blending components, increasing local inventories. The short - term absolute prices of FU and LU might follow the oil price, and the increase in FU warehouse receipts might put additional pressure on the market [2]. - **Asphalt**: On Monday, the main asphalt contract on the Shanghai Futures Exchange rose. The arrival of diluted asphalt in ports was stable in the short term, and domestic refinery raw material supply in January was not affected by the US - Venezuela geopolitical event. Supply was expected to increase slightly at the end of the year but decrease in January. The demand in the southern region still had a tail - end effect, while in the north, it was mainly for stocking. The short - term asphalt price might follow the oil price and be relatively stronger than crude oil and fuel oil [2]. - **Polyester**: TA605 and EG2605 prices declined on Monday. PX futures and spot prices also fell. The production and sales of polyester yarn in Jiangsu and Zhejiang were weak. Some polyester plants had device maintenance plans, and the MEG port inventory increased. The PX market was in a game between reality and expectation, and the ethylene glycol price was expected to oscillate after a rebound [2][4]. - **Rubber**: On Monday, the main rubber contracts declined. The inventory of natural rubber in Qingdao increased. The precipitation in the producing areas eased, and the peak - production season overseas had about one more month. The raw material price had some support, but the downstream tire demand weakened. The rubber price was expected to oscillate [4][6]. - **Methanol**: On Monday, the methanol spot prices in different regions were reported. The Iranian device shutdown would lead to a decline in arrivals in January, but the MTO device load also decreased. The port inventory increased as the unloading speed recovered. Methanol was expected to maintain a bottom - oscillating trend [6]. - **Polyolefins**: On Monday, the prices of polyolefin products were given. The supply would remain at a high level, and the downstream demand was weakening. The polyolefin market was expected to maintain a low - level oscillating trend [6]. - **Polyvinyl Chloride (PVC)**: On Monday, the PVC market prices in different regions increased. The supply was at a high - level oscillation, and the domestic demand slowed down. The PVC market was a weak - reality and strong - expectation structure, and the price was expected to maintain a bottom - oscillating trend [7]. 3.2 Daily Data Monitoring - The report provides the basis data of various energy and chemical products on December 29, 2025 and December 26, 2025, including spot prices, futures prices, basis, basis rates, price changes, and the quantile of the latest basis rate in historical data [8]. 3.3 Market News - US President Trump and Ukrainian President Zelensky met in Florida to discuss a proposed Russia - Ukraine "peace agreement", but they did not reach an agreement on key issues such as territory and economic reconstruction. Russia planned to re - evaluate its position in the peace talks [10]. - The US Energy Information Administration (EIA) reported that US crude, gasoline, and distillate inventories increased last week. As of December 19, US crude inventory increased by 405,000 barrels to 424.822 million barrels, and the inventory at the Cushing delivery center increased by 707,000 barrels to 21.57 million barrels.

Report Information - Report Name: Polyolefin Daily Report [1] - Date: December 30, 2025 [2] Investment Rating - No investment rating information provided in the report. Core View - The supply pressure of the polyolefin market is increasing as the maintenance loss of devices in December has decreased significantly compared to the previous month, and the previously shut - down devices are restarting. The demand is weak due to the seasonal off - season. The downstream load of PE has mostly declined, and although the PP operation rate is basically stable, factories are mainly digesting their previous inventory and have low willingness to make new purchases. The polyolefin rebound should be treated bearishly under the influence of supply recovery and the inventory digestion cycle in the off - season [6]. Summary by Directory 1. Market Review and Outlook - The L2605 contract of linear low - density polyethylene (LLDPE) opened higher, fluctuated during the session, and closed up at 6453 yuan/ton, up 65 yuan/ton (1.02%).

1. Report Industry Investment Rating There is no information provided in the report regarding the industry investment rating. 2. Core Viewpoints of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet surging, short - term oil prices should not be overly bearish. A range - trading strategy of buying low and selling high is maintained, but it's advisable to wait and see for now to test OPEC's export price - support willingness [3]. - For methanol, after the bullish factors are realized, the market is in short - term consolidation. With high import arrivals and expected port olefin plant maintenance, there is still pressure on the port. The overall supply is high, and the market is expected to consolidate at low levels. A wait - and - see approach is recommended for single - side trading [4]. - For urea, the market is oscillating higher. With improved supply - demand conditions, lower inventory, and support from export policies and costs, it is expected to build a bottom through oscillation. At low prices, consider buying on dips [5][6]. - For rubber, the price is oscillating weakly. Bulls and bears have different views. The current strategy is neutral, with a partial closing of the hedge of buying RU2605 and selling RU2609 recommended [8][9][11]. - For PVC, the fundamentals show low comprehensive corporate profits, high supply, and weak domestic demand. In the short - term, sentiment drives a rebound, but in the medium - term, a strategy of shorting on rallies is recommended [11][13]. - For pure benzene and styrene, the non - integrated profit of styrene is moderately low with large upward valuation repair space. Before the first quarter of next year, consider going long on the non - integrated profit of styrene [15][16]. - For polyethylene, OPEC+ plans to suspend production growth in Q1 2026, and the price may have bottomed. With no new capacity planned in H1 2026 and high - level inventory reduction, consider going long on the LL5 - 9 spread on dips [18][19]. - For polypropylene, with expected supply surplus expansion and seasonal oscillation in downstream demand, the inventory pressure is high. The price may bottom out after the supply surplus pattern changes in Q1 next year [20][21]. - For PX, it is expected to accumulate inventory slightly before the maintenance season. In the short - term, beware of correction risks, and in the medium - term, look for opportunities to go long on dips [23][24]. - For PTA, after short - term destocking, it is expected to accumulate inventory during the Spring Festival. In the short - term, beware of over - expectation correction risks, and in the medium - term, look for long - buying opportunities [25][27]. - For ethylene glycol, the overall load is still high, and the port inventory accumulation cycle will continue. In the medium - term, there is an expectation of further profit compression and load reduction. The valuation needs to be compressed without further domestic production cuts [28][29]. 3.
