Report Information - Report Title: Synthetic Rubber Weekly Report - Report Date: July 6, 2025 - Report Author: Yang Honghan - Report Source: Guotai Junan Futures Research Institute [1] Investment Rating - The report does not explicitly mention the industry investment rating. Core Viewpoints - The synthetic rubber market is expected to be under pressure and fluctuate. The cost of butadiene, a key raw material for cis - butadiene rubber, is weakening due to increased supply pressure in the domestic butadiene market. The cis - butadiene rubber market shows a pattern of both supply and demand growth, with supply growth exceeding demand growth, leading to greater fundamental pressure. However, the widening NR - BR spread to around 1,500 yuan/ton may support the single - sided price of cis - butadiene rubber [2][3][4]. Summary by Directory 1. Market Outlook and Analysis - **Futures - end Static Valuation**: The static valuation range of cis - butadiene rubber futures is 10,700 - 11,700 yuan/ton. The dynamic valuation is expected to decline due to weak butadiene trading. The upper valuation limit of the futures is around 11,700 - 11,800 yuan/ton, and the lower theoretical valuation limit is around 11,200 yuan/ton. The theoretical full - cost estimate of cis - butadiene rubber is mainly based on butadiene price * 1.02+(auxiliaries + labor) [4]. - **Butadiene Fundamentals**: Asian butadiene prices remain stable, while the domestic butadiene market is weak with a downward - trending price center. Supply is high as the industry's operating rate is still at a high level year - on - year, and weekly production is maintained at a high level with the resumption of some ethylene plants. Imports are neutral in the short term. Demand from cis - butadiene rubber procurement is neutral, and there is also rigid demand from styrene - butadiene, ABS, and SBS. Inventories show an increase in producer inventories and a slight decline in port inventories [4]. - **Cis - Butadiene Rubber Fundamentals**: The processing profit of cis - butadiene rubber is gradually returning above the break - even line, and the supply - side operating rate is expected to remain high year - on - year and increase month - on - month. Demand remains high, and substitution demand is expected to increase. Inventories are continuously at a high level year - on - year. The fundamentals have a weak driving force for synthetic rubber, and the spot is expected to fluctuate in the short term [4]. - **Cis - Butadiene Rubber Futures**: In the short term, cis - butadiene rubber is under pressure. The cost side is affected by the weakening butadiene market, and the market shows a pattern where supply growth exceeds demand growth, resulting in greater fundamental pressure. The widening NR - BR spread may support the price [4]. - **Strategy**: Short - term weakness in single - sided trading; the NR - BR spread is expected to widen [4]. 2. Butadiene Fundamentals - **Pricing Stage**: Butadiene is currently in the supply - demand pricing stage, with a low correlation with the raw material end [7]. - **Capacity Expansion**: To support the expansion of downstream industries such as ABS, SBS, styrene - butadiene, and cis - butadiene rubber, butadiene capacity is continuously expanding, and the expansion speed and amplitude are slightly faster than those of downstream industries at certain stages [9]. - **New Capacity**: In 2024, a total of 380,000 tons of new capacity was put into operation, and in 2025, a total of 860,000 tons of new capacity is expected to be put into operation, mainly through the C4 extraction process [11]. - **Supply - side - Operating Rate**: The operating rate of the butadiene industry remains at a high level year - on - year, and weekly production is high. Some enterprises have maintenance plans, which will affect production to some extent [13][14][15]. - **Net Imports**: The report provides data on butadiene imports, exports, and net imports, but does not make a specific analysis of the trend [16]. - **Demand - side - Capacity of Cis - Butadiene and Styrene - Butadiene Rubber**: The capacity of cis - butadiene and styrene - butadiene rubber is also expanding, with new projects being put into operation in different regions [17][18][19]. - **Demand - side - Operating and Maintenance of Cis - Butadiene and Styrene - Butadiene Rubber**: The operating rates of cis - butadiene and styrene - butadiene rubber show different trends, and some enterprises have maintenance and production adjustment plans [22][23][24]. - **Demand - side - Capacity of ABS and SBS**: The capacity of ABS and SBS is also increasing, with significant capacity increments in 2024 and 2025 [25][26][27][28]. - **Demand - side - Fundamentals of ABS and SBS**: The operating rate, profit, inventory, and capacity utilization rate of ABS and SBS show different trends, reflecting the market supply - demand relationship [29][30]. - **Inventory - side**: Butadiene producer inventories are increasing, while port inventories are slightly decreasing [31][32][33]. 3. Synthetic Rubber Fundamentals - **Cis - Butadiene Rubber - Supply - Production**: The weekly production of high - cis cis - butadiene rubber shows different trends in different years, and the operating rate remains at a certain level [38]. - **Cis - Butadiene Rubber - Supply - Cost and Profit**: The theoretical production cost, profit, and gross profit margin of cis - butadiene rubber show different trends over time [40][41][42]. - **Cis - Butadiene Rubber - Supply - Import and Export**: The monthly import and export volumes of cis - butadiene rubber show different trends in different years [43][44]. - **Cis - Butadiene Rubber - Supply - Inventory**: The weekly enterprise inventory, futures inventory, and trader inventory of cis - butadiene rubber show different trends [47][48]. - **Cis - Butadiene Rubber - Demand - Tires**: The inventory and operating rate of domestic tires (full - steel and semi - steel) show different trends, reflecting the demand for cis - butadiene rubber in the tire industry [51][52].

From January to May, the import volume of synthetic rubber increased by 13% year - on - year to 587,000 tons. The overall import volume showed an increasing trend, and the import volume in June may continue to grow without special circumstances [11]. 6. Conclusion and Outlook - In the short - term, the synthetic rubber market has supply pressure, and the demand side is difficult to improve significantly. The cost side supports prices, and the futures price is expected to fluctuate. In the long - term, the market scale is expected to expand with industry development, and investors should pay attention to macro - policies and supply - demand changes [12].

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The short - term trend of synthetic rubber will follow crude oil and remain in a high - level oscillation. In the medium term, due to the high supply and the supply growth rate exceeding the demand growth rate, there is still significant fundamental pressure. The current main contradiction in the market may be the geopolitical conflict from a macro perspective [2][4]. 3. Summary by Relevant Catalogs 3.1行情研判 - **Futures - end static valuation**: The static valuation range of butadiene rubber futures fundamentals is 11,400 - 12,000 yuan/ton. The dynamic valuation is expected to oscillate. The upper valuation of the futures price is around 12,000 - 12,100 yuan/ton, and when the main BR2507 contract has a premium of about 100 yuan/ton over the market price in Shandong, there is a risk - free arbitrage opportunity. The theoretical bottom valuation range is 11,400 yuan/ton [4]. - **Butadiene fundamentals**: The price of Asian butadiene remains stable, and the domestic butadiene market has seen improved short - term transactions, with prices oscillating around 9,500 yuan/ton. The industry's operating rate is still high year - on - year and has increased month - on - month. Short - term imports are neutral. Demand from butadiene rubber remains neutral, and there is also rigid demand from styrene - butadiene rubber, ABS, and SBS. Inventories of production enterprises and ports have increased slightly. Overall, butadiene is expected to oscillate with support [4]. - **Butadiene rubber fundamentals**: The processing profit of butadiene rubber has gradually returned above the break - even line, and the supply - side operating rate is expected to remain high year - on - year and increase month - on - month. The apparent demand this week remains high, but the substitution demand is expected to decline. Inventories have been at a high level year - on - year. The current fundamentals have a weak driving force, and spot prices are expected to oscillate in the short term [4]. - **Butadiene rubber futures**: In the short term, the escalating geopolitical conflict in the Middle East has pushed up international energy prices, and synthetic rubber, as a crude oil chemical product, may oscillate at a high level following oil products.
