Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Views - The pure benzene market is experiencing weak demand, with rising port inventories and ongoing supply pressure. The demand side is unlikely to improve significantly in the short term, and the oversupply situation will persist. [2][3] - The styrene market is facing a mismatch between supply and demand, with low demand unable to support price rebounds. Although macro - policy may provide some support, the weak supply - demand pattern will continue. [4][5] 3. Summary by Section Pure Benzene - **Market Overview**: The pure benzene market is operating weakly, with port inventories rising again and increasing supply pressure. Downstream开工率 is low, and product inventories in some industries are high, dragging down demand. [3] - **Supply and Demand**: Supply is abundant, but due to weak downstream demand, the supply - demand contradiction has not been effectively resolved. The weak demand has led to a lack of price support and increased supply pressure. [3] - **Market Outlook**: Given the continued low - level downstream demand and high inventories in some industries, the demand side of the pure benzene market is unlikely to improve significantly in the short term. Port inventories may remain high in the coming weeks, and the basis may continue to weaken. [3] - **Key Indicators**: Supply is sufficient, port inventories are rising, downstream开工率 is falling, the monthly spread is weak, and the basis is weakening. The international arbitrage window is closed. [7] - **Supply Details**: Last week, new maintenance at Yulong Petrochemical, Shengxing Petrochemical, Urumqi Petrochemical, and Guangzhou Petrochemical occurred, but overall supply remained high. For hydrobenzene, there is more spot supply, and some plants have reduced their loads. [10] - **Import Situation**: Pure benzene imports are rising. Affected by US tariff policies, the US - Asia arbitrage window is closed, and most of South Korea's pure benzene is flowing to China, increasing import pressure. [12][14] - **Downstream Situation**: Downstream profits are weakening, and开工率 is seasonally declining. Overall demand is weakening, and downstream inventories are generally high. [16][18][23] - **Inventory Situation**: As of October 22, pure benzene port inventories were 99,000 tons, up 9,000 tons from last week. Due to weak downstream demand, inventories are expected to continue to accumulate. [28] - **Price Spread**: The pure benzene - naphtha price spread weakened after a brief recovery, and the BZN spread is low, indicating low pure benzene valuation. [30][32] Styrene - **Market Overview**: The styrene market continues to operate weakly, with significant pressure on both the supply and demand sides. Although downstream开工率 has increased,提货 performance is average, and port inventories are under pressure. [4] - **Supply and Demand**: In the short term, there are still maintenance plans, which may lead to some production cuts. However, new plants will impact the market supply. Downstream demand growth is limited due to weak terminal demand and high inventories in some downstream industries. [4] - **Cost and Price**: The non - integrated cost of styrene has decreased due to falling international oil prices, and losses have deepened. Although the supply - demand situation is weak, the valuation of the November contract is low, and the downward space is relatively limited due to potential macro - policy support in late October. [4] - **Market Outlook**: This week, styrene production is expected to decline slightly due to previous plant shutdowns. However, considering the concentrated downstream production in November and December, the supply - demand mismatch may intensify, and the weak supply - demand pattern will continue. [5] - **Key Indicators**: Supply has decreased slightly, downstream demand recovery space is limited, the EB2511 - EB2512 spread is suitable for reverse arbitrage, and port inventories are still high. [7] - **Production Situation**: Styrene开工率 has declined, and production has decreased. In September, production decreased but was still higher than in previous periods. The cumulative supply from January to September increased by 17.28% year - on - year. [36][38] - **Import and Export Situation**: In September, styrene imports were 26,200 tons, a slight increase from the previous month, and exports were 31,500 tons, showing significant year - on - year and month - on - month growth. [41] - **Inventory Situation**: As of October 22, styrene port inventories increased to 203,000 tons, up 6,000 tons from last week. Inventories are likely to continue to accumulate in late October. [45] - **Downstream Situation**: Downstream开工率 has weakened, and the profits of 3S products have declined. Downstream production is high, and there are no obvious signs of inventory reduction. [47][55] - **Basis Situation**: The styrene basis has been fluctuating narrowly. Due to weak downstream demand and high inventories, the basis is still weak and may decline further in the future. [57]

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - For PTA, near - term TA partial device load increased,开工 slightly rose, polyester load remained stable, inventory slightly accumulated, basis weakened, and spot processing fee stayed low; PX domestic operation declined, overseas partial maintenance took place, PXN widened, disproportionation and isomerization benefits were stable, and the US - Asia aromatics spread widened. In the future, polyester has no unexpected performance, TA will gradually enter the inventory - accumulation stage, but the current low processing fee has lasted for a long time. Pay attention to additional maintenance. With limited far - month production, the processing fee center may gradually recover [2]. - For MEG, near - term domestic maintenance and restart co - existed, load still slightly increased, overseas maintenance took place, arrivals were stable but shipments were dull, port inventory continued to slightly accumulate at the beginning of next week, basis was stable, and coal - based benefits and ratios further shrank. In the future, EG's existing operation has reached a relatively high level, combined with new device production, it will enter a continuous inventory - accumulation stage. However, after the coal - based benefits and ratios weaken, the supply side may have some negative feedback. Also, coal prices have strengthened recently. Pay attention to the selling put opportunities near the coal - based cost [2]. - For polyester staple fiber, near - term device operation was stable, operation rate remained at 94.3%, sales improved, and inventory slightly decreased. On the demand side, the operation rate of polyester yarn slightly increased, both raw material and finished product inventories decreased, and benefits slightly improved.

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The core contradictions affecting the current trend of propylene include sufficient supply but insufficient demand in the main downstream PP, small price differences between PP powder, granules, and propylene, and weak overall downstream, lacking upward drivers. Additionally, the PDH cost has collapsed, with the CP October contract price dropping unexpectedly [3]. - There are some positive factors, such as a slight reduction in supply in the Shandong market due to the shutdown of Yulong cracking, the maintenance of Lihuayi PDH, and the shutdown of Jingbo K - cot. There are also some buyers after the decline in spot prices, and the increase in recent maintenance at the PP end has temporarily relieved the supply - side pressure [3]. - Negative factors include the possibility of repeated submissions of the "anti - involution" affecting expectations, and the spot price being easily affected by individual device fluctuations. In the past two weeks, the supply - demand gap has slightly decreased due to the maintenance of some devices. Also, after the decline in propane, the PDH profit has expanded, but propylene and PP cannot bear the high profit, and the PP downstream remains weak [4][5]. 3. Summary by Related Catalogs 3.1 Propylene Price Forecast and Hedging Strategy - **Price Forecast**: The monthly price range forecast for propylene is 5800 - 6200 yuan/ton. The current 20 - day rolling volatility is 0.1067, and the historical percentage of the current volatility in the past 3 years is 0.6333 [2]. - **Hedging Strategy** - **Inventory Management**: For enterprises with high finished - product inventory worried about price drops, they can short - allocate propylene futures at high prices (50% hedging ratio, recommended entry range 6300 - 6400 yuan/ton for PL2601) to lock in profits. They can also sell call options (25% hedging ratio, recommended entry range 140 - 150 for PL2601C6200) to collect premiums and reduce costs [2]. - **Procurement Management**: For enterprises with low regular procurement inventory and aiming to purchase according to orders, they can buy propylene futures at low prices (25% hedging ratio, recommended entry price 5800 yuan/ton for PL2601) to lock in procurement costs. They can also sell put options (25% hedging ratio, recommended entry range 50 - 70 for PL2601P5800) to collect premiums and reduce procurement costs [2]. 3.2 Industrial Data Summary - **Upstream Raw Material Prices**: On October 21, 2025, Brent was at $61.36/barrel (+$0.56 day - on - day, -$0.92 week - on - week), WTI was at $57.58/barrel (+$0.65 day - on - day, -$0.6 week - on - week), and other upstream prices also showed various changes [7]. - **Mid - stream Prices**: The price of propylene in the East China region on October 21, 2025, was 6075 yuan/ton (unchanged day - on - day, - 140 yuan/ton week - on - week), and prices in other regions also had corresponding fluctuations [7]. - **Downstream Prices**: The price of polypropylene granules on October 21, 2025, was 6550 yuan/ton (unchanged day - on - day, - 50 yuan/ton week - on - week), and prices of other downstream products also changed [7]. - **Profits**: Profits in the mid - upstream, such as the profit of propylene PDH - FEI, were 307.34 yuan/ton (-65.37 yuan/ton day - on - day, -95.26 yuan/ton week - on - week), and profits in different sectors showed different trends [7]. - **Price Spreads**: The spread between PP granules and propylene on October 21, 2025, was 440 yuan/ton (-30 yuan/ton day - on - day, +170 yuan/ton week - on - week), and other price spreads also had corresponding changes [7].

Core Viewpoint - The domestic melamine industry is experiencing a deep adjustment period characterized by supply-demand imbalance, leading to intensified market competition and declining prices since 2025 [1][2]. Supply and Demand Imbalance - The domestic melamine market ended the first half of 2025 with a downward trend, primarily driven by supply-demand imbalance. The production capacity reached 2.31 million tons in 2024 and is expected to increase to 2.6 million tons by the end of 2025, with an additional 940,000 tons of new capacity expected to come online in the following years [2]. - Demand remains weak, particularly from the construction sector, which accounts for nearly 60% of melamine consumption. The sales area of new commercial housing is projected to decline by 12.9% in 2024, and the consumption of melamine in the artificial board industry is expected to drop to 771,100 tons in 2025, a further decrease from 2024 [2]. Profit Margin Compression - The supply-demand pressure has directly impacted corporate profitability, with melamine prices dropping by 20% year-on-year in 2025. As of mid-October, the cash reference price for melamine was 5,084 yuan per ton, while production costs for companies using external urea ranged from 4,778 to 4,856 yuan, resulting in a profit margin of only 228 yuan, down 16 yuan from the previous week [3]. - The core reasons for the shrinking profit margins include persistent weak demand and limited support from raw material prices. The average price of urea in the third quarter of 2025 was 1,762 yuan, reflecting a 6.37% decline from the previous quarter and a 17.27% year-on-year drop [3]. Export Challenges - The export volume of melamine reached 427,300 tons in the first eight months of the year, a 6.2% increase year-on-year. However, the average export price fell by 166.3 USD, resulting in a situation where increased export volume did not translate into higher profits [4]. Industry Structural Adjustments - The industry is witnessing three major trends: increased concentration of enterprises, heightened regional concentration, and a shift towards green and high-end transformation. The market share of the top five melamine companies (CR5) rose from 38% in 2020 to 52% in 2025, indicating a 14 percentage point increase over five years [5]. - By the end of 2025, the total melamine production capacity in China is expected to reach 2.6 million tons, with five regions (Xinjiang, Shandong, Sichuan, Henan, and Shanxi) accounting for 77.5% of this capacity [5]. - The tightening of environmental regulations and the upgrading of downstream demand are driving the need for green and high-end transformation in the industry. The implementation of the new national standard for formaldehyde emissions in 2026 is expected to indirectly boost the demand for environmentally friendly melamine [5][6].
