September 20th, news
As of September 19, 2026, the average spot price of styrene-butadiene rubber (SBR) in China was reported at 15,691.67 CNY per ton. Using the mean difference method, the current market signal is a weak rebound (slightly bearish), with prices generally fluctuating within a range. Both short-term and long-term price percentiles are in the mid-high range or above, indicating limited upside potential. On the fundamental side, high international crude oil prices provide strong cost support, but there is evident resistance from downstream buyers to high-priced supplies. Additionally, the expected price adjustments by tire manufacturers have yet to be fully transmitted, so the short-term market trend is expected to remain in a consolidation phase.

VII. Fundamental Developments
Cost side: The international crude oil market remains at high levels, providing strong cost support for upstream raw materials of styrene-butadiene rubber.
Spot market: In mid-September, the SBR (styrene-butadiene rubber) market in the Jiangsu and Zhejiang regions of China was consolidating within a range. After merchants slightly reduced their offers, the mainstream prices for Fushun, Lanhua, Yangzi, and Jihua 1502 were reported at 155,500 to 158,000 CNY per ton. Downstream inquiries were mainly based on need, with a clear resistance to high-priced supplies, leading to stagnant transactions.
Downstream: In mid-September, tire giants such as Zhongce and Sailun in China successively issued price increase notices, raising the prices of all categories of tires. Some companies stated that the current price increase still cannot cover the costs, and there is an expectation of another price adjustment in October.
