Report Overview - Report Title: Synthetic Rubber Weekly Report - Report Date: October 19, 2025 - Report Author: Yang Honghan - Report Institution: Guotai Junan Futures Research Institute 1. Report Industry Investment Rating No relevant content provided. 2. Report Core Views - Synthetic Rubber: Short - term shock operation. The fundamentals of butadiene and cis - butadiene rubber are under pressure, with supply growth outpacing demand growth. However, the valuation is neutral to low, and with many important macro - events, prices are expected to fluctuate [2][4][5]. - Butadiene: In the short - term, supply and demand both increase, inventory is neutral, and it will operate in a shock pattern. In the medium - to - long - term, supply pressure is the main contradiction, and the fundamentals are still under significant pressure, expected to be in a weak pattern [7]. 3. Summary by Directory 3.1 Synthetic Rubber Views Supply - This week, some cis - butadiene rubber plants restarted, while others stopped for maintenance. The production of high - cis butadiene rubber was 30,000 tons, a 0.18% increase from last week, and the capacity utilization rate was 74.82%, up 0.13 percentage points. In the next period, there are no new plant restarts or shutdowns, but centralized maintenance will increase significantly at the end of October [4]. Demand - Rigid Demand: The capacity utilization rate of tire sample enterprises is expected to fluctuate slightly. Some enterprises are still flexibly controlling production to manage inventory. - Substitute Demand: The NR - BR main contract spread remains high, so the overall demand for butadiene rubber maintains a high year - on - year growth rate. Inventory - As of October 15, 2025, the inventory of domestic cis - butadiene rubber sample enterprises was 32,800 tons, a 1.42% increase from the previous period. After the holiday, raw material and synthetic rubber prices declined, and sample trade enterprise inventories decreased [4]. Valuation - The static valuation range of cis - butadiene rubber futures is 10,400 - 11,300 yuan/ton, and the dynamic valuation is expected to gradually decline. The upper valuation limit of the market is 11,200 - 11,300 yuan/ton, and the lower theoretical valuation limit is 10,400 - 10,500 yuan/ton [4]. Strategy - Single - side: Implement range strategies based on the fundamental static valuation. The upper pressure is 11,200 - 11,300 yuan/ton, and the lower support is 10,400 - 10,500 yuan/ton. - Cross - variety: When the NR - BR spread is at a high valuation, short the spread when it is high [5]. 3.2 Butadiene Views Supply - This week, domestic butadiene production decreased to 102,200 tons, a 2.39% decline, and the capacity utilization rate was 65.79%, down 1.58%. Next week, the sample enterprise production is expected to be about 103,800 tons, a slight increase [7]. Demand - Synthetic Rubber: The operating rates of cis - butadiene rubber and styrene - butadiene rubber remain high, and the demand for butadiene maintains a high year - on - year level. - ABS: Inventory pressure is high, and the demand for butadiene is expected to remain constant with limited incremental demand. - SBS: The operating rate has slightly increased, and the demand for butadiene remains at a rigid level [9]. Inventory - In the period from October 9 - 15, 2025, the total inventory of domestic butadiene samples increased slightly, with a 3.49% increase from last week. The enterprise inventory decreased by 3.23%, and the port inventory increased by 10.99% [9]. View - In the short - term, supply and demand both increase, inventory is neutral, and it will operate in a shock pattern. In the medium - to - long - term, supply pressure is the main contradiction, and the fundamentals are still under significant pressure, expected to be in a weak pattern [7]. 3.3 Industry Capacity and Production Butadiene Capacity - To match the expansion of downstream industries, butadiene capacity has been continuously expanding, with the speed and amplitude slightly faster than that of downstream industries at certain stages. In 2024, the new capacity was 380,000 tons, and in 2025, it is expected to be 860,000 tons [14][16]. Downstream Product Capacity - Cis - Butadiene Rubber: Many enterprises have new or expanded production capacity, such as Zhejiang Petrochemical, Zhejiang Transfar Group, etc. - Styrene - Butadiene Rubber: Some enterprises in different regions have planned new production capacity in 2026, such as Guangxi Petrochemical and Yanshan Petrochemical [23][24]. - ABS and SBS: There has been significant capacity expansion in recent years. In 2024, the ABS capacity increased by 2.06 million tons, and in 2025, it is expected to increase by 1.5 million tons. For SBS, the capacity increased by 160,000 tons in 2024 and is expected to increase by 250,000 tons in 2025 [35].
