Core Viewpoint - The market for butadiene rubber is experiencing a downward trend, with prices hitting a new low since its listing, primarily due to declining costs and macroeconomic issues affecting demand [1][2]. Price Movement - As of November 5, 2025, the price of BR9000 in the North China market was approximately 9900 CNY/ton, down 600 CNY/ton from October 31, with a low point of around 9700 CNY/ton, marking a return to the price levels of the second quarter of 2023 [2][4]. Macro Environment - The macroeconomic outlook for 2025 is characterized by a transition from rapid growth to high-quality development, with expected demand growth slowing down. The impact of overseas tariff issues is overshadowing optimistic domestic expectations [4][6]. Supply and Demand Dynamics - The butadiene market is facing increased supply, leading to a downward price trend. As of November 5, 2025, the price of butadiene in the Jiangsu-Zhejiang region was 6825 CNY/ton, with a price difference from rubber prices at 2975 CNY/ton, indicating a significant supply-demand imbalance [4][6]. Inventory Levels - The overall supply of butadiene rubber is expected to grow more than demand, with inventory levels increasing by approximately 36% compared to the previous low price point. This high inventory level is likely to exert downward pressure on prices [6][7]. Future Expectations - The current market conditions suggest a lack of clear support for price stabilization, with expectations of further declines in raw material prices and a slowdown in downstream demand, particularly in the fourth quarter of 2025 [6][7].

Report Overview - Report Title: Synthetic Rubber Weekly Report - Report Date: November 9, 2025 - Report Author: Yang Honghan - Report Institution: Guotai Junan Futures Research Institute 1. Report Industry Investment Rating - Not provided in the report 2. Report Core View - The short - term trend of synthetic rubber is volatile, and the fundamentals still face pressure. The production capacity utilization rate of high - cis butadiene rubber decreased. In the medium term, a strategy of shorting on rallies is recommended, without chasing short positions. The nr - br spread is expected to oscillate at a high level [2][4]. - Butadiene is in a weak operating state. In the short term, the low absolute price drives downstream replenishment, leading to improved trading and price stabilization. In the medium - long term, supply pressure remains the primary contradiction, and the fundamentals are still under significant pressure [6]. 3. Summary by Relevant Catalogs 3.1 Synthetic Rubber 3.1.1 Supply - During the cycle, the butadiene rubber plants of Yangzi Petrochemical, Zhejiang Petrochemical, and Zhenhua New Materials were shut down for maintenance, while the butadiene rubber plant of Sichuan Petrochemical restarted. The production capacity utilization rate further declined. The output of high - cis butadiene rubber was 26,500 tons, a decrease of 400 tons from last week, a month - on - month decrease of 1.31%, and the production capacity utilization rate was 66.02%, a month - on - month decrease of 0.88 percentage points. It is expected that Yangzi Petrochemical's butadiene rubber plant will restart in the next cycle, and the Maoming butadiene plant and Zhejiang Transfar's 120,000 - ton/year rare - earth butadiene rubber plant are scheduled for maintenance at the end of November and in December respectively [4]. 3.1.2 Demand - In terms of rigid demand, the production capacity utilization rate of tire sample enterprises increased slightly during the cycle. It is expected that the production capacity utilization rate of sample enterprises will remain stable with a slight downward trend in the next cycle. The production of most enterprises will remain stable to meet order demands, but it is reported that some enterprises have maintenance plans in the middle of the month, which may drag down the overall production capacity utilization rate. In terms of alternative demand, the current spread between the nr - br main contracts remains high, and the alternative demand also remains at a high level. Therefore, the overall demand side of butadiene rubber maintains a high year - on - year growth rate [5]. 3.1.3 Inventory - As of November 5, 2025, the domestic butadiene rubber inventory was 29,300 tons, a decrease of 1,600 tons from the previous cycle, a month - on - month decrease of 5.15%. During the cycle, the supply of raw material butadiene was sufficient, and the negotiation focus continued to decline. Under the continuous negative drag of the cost side, industry players generally had a clear expectation of the continuous decline of the recent market. Downstream price - pressing procurement led to a significant decline in the negotiation focus of private resources. At the same time, the output was affected by the maintenance of some production enterprises, the circulating supply of goods was limited, resulting in the spot offer being significantly higher than that of private resources, and the sales performance was blocked. The inventories of sample production enterprises and sample trading enterprises both decreased [5]. 3.1.4 Valuation - Currently, the static valuation range of butadiene rubber futures fundamentals is 9,500 - 10,400 yuan/ton. The valuation logic has shifted from cost - side support for the lower - end valuation to the nr - br spread providing support for the lower - end valuation. For the upper - end valuation, 10,300 - 10,400 yuan/ton on the futures market may be the high point of the fundamental upper - end valuation. When the main contract BR2501 has a premium of about 100 yuan/ton over the market price in Shandong (the single - month holding cost is around 90 yuan/ton), there is a risk - free arbitrage opportunity of holding spot and shorting futures on the market, and hedging positions will gradually increase the pressure on the upside space of the futures market [5]. 3.2 Butadiene 3.2.1 Supply - In the current cycle (from October 31 to November 6, 2025), the estimated weekly output of Chinese butadiene industry sample enterprises was 109,200 tons, an increase of 5,100 tons from the previous cycle, a month - on - month increase of 4.85%. During the week, the plants of Nanjing Chengzhi, Sierbang, Yanshan Petrochemical, Guangzhou Petrochemical, and Zhenhai Refining & Chemical remained shut down, but the plants of Jilin Petrochemical Phase I, Fushun Petrochemical, and Sichuan Petrochemical resumed production, resulting in a continuous increase in output. Next week, it is expected that the weekly output of Chinese butadiene sample enterprises will be around 112,500 tons, continuing to increase from the current cycle. There are no new plant shutdown and maintenance plans in the next cycle, and the previously restarted plants will stably release output, leading to a continuous recovery of the output of domestic operating plants. At the same time, pay close attention to the output of Guangxi Petrochemical [6]. 3.2.2 Demand - In the synthetic rubber sector, the medium - term operating rates of butadiene rubber and styrene - butadiene rubber remain high, and the demand for butadiene maintains a high year - on - year level. In the short term, as butadiene plants undergo maintenance in November, it is expected that the rigid demand for butadiene in synthetic rubber procurement will decrease. In the ABS sector, the inventory pressure is relatively high, and it is expected that the demand for butadiene will only be maintained at a constant level, with limited incremental demand. In the SBS sector, the operating rate has slightly increased, and the rigid demand for butadiene procurement remains unchanged [8]. 3.2.3 Inventory - In the current cycle (from October 30 to November 6, 2025), the total inventory of domestic butadiene samples fluctuated slightly, with a month - on - month decrease of 1.67% from last week. Among them, the inventory of sample enterprises increased by 3.71% month - on - month compared with last week. During the cycle, some plants resumed production, and at the same time, the significant decline in the market led to a slowdown in the trading rhythm, resulting in inventory accumulation for some suppliers. The inventory of sample ports decreased by 6.88% month - on - month compared with last week. Although there were imported vessels arriving at the port during the week, the normal consumption of downstream raw material inventories led to a decrease in the inventory of sample ports. Although the short - term tradable supply is limited, the import volume remains high, and merchants' sentiment remains cautious. Pay attention to future inventory changes [8].

Report Information - Report Name: Synthetic Rubber Weekly Report [1] - Report Date: October 26, 2025 [1] - Analyst: Yang Honghan [1] - Investment Advisory Qualification Number: Z0021541 [1] Report Industry Investment Rating - Not provided in the report Core Viewpoints - The synthetic rubber market is expected to operate within the fundamental valuation range. The fundamentals of butadiene and cis - butadiene rubber face pressure, mainly from high supply, with supply growth exceeding demand growth, increasing inventory pressure in the industry chain. However, the valuation is moderately low, and with many important macro - events, the price is expected to fluctuate. [2][4] - The fundamentals of butadiene are gradually under increasing pressure, with high - supply pressure expected to persist in the medium - term, leading to a weak trend. [5] Summary by Directory This Week's Cis - Butadiene Rubber Viewpoints Supply - This week, the impact of maintenance at Qilu Petrochemical and Yangzi Petrochemical's cis - butadiene rubber plants became apparent, and the load of some private plants decreased slightly. The output of high - cis butadiene rubber was 29,500 tons, a decrease of 500 tons from last week, a 1.84% MoM decline, and the capacity utilization rate was 73.45%, a 1.37 - percentage - point MoM decrease. Next week, Zhejiang Petrochemical is expected to shut down for maintenance, and the specific implementation time of Sichuan Petrochemical is to be determined. There are also maintenance expectations for Zhenhua New Materials, Maoming's cis - butadiene rubber plant, and Zhejiang Transfar's 120,000 - ton/year rare - earth cis - butadiene rubber plant from November to December, so the short - term supply of some spot resources is expected to remain tight. [4] Demand - In terms of rigid demand, the capacity utilization rate of tire sample enterprises increased slightly this week. Snowfall in Heilongjiang and Inner Mongolia was earlier than usual, leading to concentrated demand for winter tires. Semi - steel tire enterprises actively arranged production, driving up the capacity utilization rate. The production of all - steel tire enterprises returned to normal levels this week, also driving up the overall capacity utilization rate. Next week, the capacity utilization rate of sample enterprises is expected to fluctuate slightly. Semi - steel tire enterprises will maintain stable production, and all - steel tire enterprises will keep production stable overall. In terms of substitution demand, the spread between the NR - BR main contracts remains at a high level, so the overall demand for cis - butadiene rubber maintains a high year - on - year growth rate. [4] Inventory - As of October 22, 2025, the domestic inventory of cis - butadiene rubber was 33,200 tons, an increase of 400 tons from the previous period, a 1.25% MoM increase. This week, the spot market was driven by the expectation of a cooling of trade frictions and the strengthening of natural rubber. While the mainstream supply price rebounded, low - price transactions improved. However, due to more maintenance of domestic cis - butadiene rubber plants recently, some sample production enterprises stocked up, resulting in a continuous increase in the inventory level of sample production enterprises and a decrease in the inventory of sample trading enterprises. [4] Valuation - Currently, the static fundamental valuation range of cis - butadiene rubber futures is 10,400 - 11,300 yuan/ton. The dynamic valuation is expected to gradually decline due to the increase in butadiene arrivals. The upper valuation limit of the fundamentals is around 11,200 - 11,300 yuan/ton on the futures market. When the main BR2512 contract has a premium of about 100 yuan/ton over the Shandong market price, there is a risk - free arbitrage opportunity for holding spot and shorting futures, which will increase the pressure on the upper - limit space of the futures market. The lower valuation limit is expected to be supported by butadiene from the cost side, with the theoretical lower - limit valuation range of the futures market at 10,400 - 10,500 yuan/ton. The overall static valuation of cis - butadiene rubber is currently moderately low. [4] Strategy - Unilateral: Implement a range strategy based on the static fundamental valuation. The upper pressure is at 11,200 - 11,300 yuan/ton (mainly following the trend of cis - butadiene rubber spot), and the lower support is at 10,400 - 10,500 yuan/ton (the cost of cis - butadiene rubber anchored by butadiene). - Cross - variety: The spread between NR - BR is at a high valuation, but due to insufficient driving forces, it is expected to fluctuate. [4] This Week's Butadiene Viewpoints Supply - This week (October 17 - 23, 2025), the estimated weekly output of Chinese butadiene industry sample enterprises was 101,900 tons, a decrease of 300 tons from the previous period, a 0.25% MoM decrease. Next week, the estimated weekly output of Chinese butadiene sample enterprises is about 106,000 tons, an increase from this week. Although Sichuan Petrochemical plans to shut down for maintenance on the 25th, the output of enterprises in the Northeast and Shandong will gradually return to normal, increasing the overall output. [5] Demand - In the synthetic rubber sector, the operating rates of cis - butadiene rubber and styrene - butadiene rubber remain high, maintaining a high year - on - year demand for butadiene. With the resumption of cis - butadiene rubber plants, the rigid demand for butadiene in synthetic rubber is expected to increase. In the ABS sector, due to high inventory pressure, the demand for butadiene is expected to remain constant with limited incremental demand. In the SBS sector, the operating rate increased slightly, maintaining rigid demand for butadiene with little change. [5] Inventory - This week (October 16 - 22, 2025), the total inventory of domestic butadiene samples decreased, a 9.29% MoM decrease. Among them, the inventory of sample enterprises increased slightly by 1.83% MoM. There were plant changes during the period, and some downstream plants in East China shut down for maintenance, causing slight fluctuations in butadiene inventory. The inventory at sample ports decreased significantly by 20.13% MoM. The arrival of ships was limited this week, and the tradable volume was low, resulting in a phased reduction in inventory. However, merchants expect sufficient imports in October, so inventory changes need to be closely monitored. [5] Viewpoint - In the short - term, both supply and demand are increasing, and the inventory is neutral, so butadiene is expected to fluctuate. In the medium - term, the supply pressure of butadiene remains the main contradiction, and the fundamentals are still under significant pressure, leading to a weak trend. [5] Butadiene Fundamentals - Butadiene is currently in the supply - demand pricing stage, with a low correlation with the raw material end. [8] - To support the expansion of downstream industries such as ABS, SBS, styrene - butadiene, and cis - butadiene, butadiene production capacity has been continuously expanding, with the expansion speed and amplitude slightly faster than those of downstream industries at certain stages.
