September 9 news
On September 8, 2026, the Chinese styrene-butadiene rubber (SBR) market maintained a high level of operation. The rise in international crude oil prices bolstered the cost support for upstream raw materials such as butadiene and styrene, leading to consecutive increases in factory prices by major manufacturers. The market sentiment is bullish; however, from the perspective of the average difference indicator, the current SBR is in a deep correction phase, with a trend that is more volatile. In the short term, prices are already at a high level, and the room for further increases is relatively limited.
The most recent available data is up to September 8, 2026, and it is recommended to refer to real-time data.
1. Mean Difference Variation Table
| Average Difference Type | Today (2026.9.8) Value (CNY/ton) | Yesterday (2026.9.7) Value (CNY/ton) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference D5 | 273.33 | 358.34 | - |
| 10-day Average Difference D10 | 279.17 | 299.16 | - |
| 20-day Average Difference D20 | 310.00 | 246.25 | + |
2. Signal Status Judgment
The current mean difference change symbol combination is (-, -, +), corresponding to a deep correction (bearish, of a corrective nature).
3. Trend Direction Conclusion
The current price trend is oscillating, reason: the change directions of the 5-day, 10-day, and 20-day average differences from the previous day are not completely consistent, not meeting the criteria for a clear upward/downward trend, thus it is in an oscillating range.
4. Position Space Reference
Butadiene rubber 60-day and 3-month cycle prices are in the 5th tier (high), while the 1-year cycle price is in the 4th tier (upper mid-range). The short-term upside is limited, and there is a need to be cautious of the risk of a pullback from high levels.

6. Market Dynamics
Regional Market Update: On September 8, the mainstream price of SBR 1502 in the Jiangsu and Zhejiang regions of China was 159,000 to 162,000 CNY/ton. In the southwestern region, Qilu 1502 was quoted at 161,000 CNY/ton, and in the northwestern region, Jihua 1502 was quoted at 159,000 CNY/ton. Prices in all regions remained high.
Manufacturer price adjustment: On September 8, the prices of emulsion styrene-butadiene rubber from PetroChina's East China and Northeast sales companies were increased by 300 CNY/ton, with the warehouse price in East China reaching 16,000 CNY/ton; since September, the cumulative price increase by major manufacturers has reached up to 900 CNY/ton, showing a strong intention to maintain prices.
Cost support: Both upstream butadiene and styrene prices remain at historically high levels in the short term. The continued rise in international crude oil prices provides strong cost support. Additionally, since the Yanchang Petrochemical SBR plant resumed operations in September, supply has yet to be fully released, leaving the market in a relatively tight supply-demand balance.
Import and export data: In July 2026, China imported 579,000 tons of natural and synthetic rubber, a decrease of 12.8% year-on-year, further highlighting the strengthening support from China’s supply side.
