October 19th, news
The current styrene-butadiene rubber differential signal shows a weak rebound (bearish) state, with prices at a high level in the 3-month cycle and at a mid-high level in the 1-year cycle. Coupled with the strong resistance from downstream to high-priced supplies, although there is some cost support due to high crude oil prices, the short-term price is likely to be mainly characterized by wide fluctuations.
I. Data Description
The latest available data is up to October 18, 2026, and it is recommended to refer to real-time data.
II. Table of Finite Differences
| Average Difference Type | Value on 2026.10.18 | Value on 2026.10.17 | Direction of Change |
|---|---|---|---|
| 5-Day Average Difference (D5) | -55 | -120 | + |
| 10-Day Average Difference (D10) | -155 | -110.83 | - |
| 20-Day Average Difference (D20) | 171.25 | 215.41 | - |
Three, Signal Status Judgment
The current combination of the three differences is (+, -, -), which belongs to a weak rebound (bearish) signal.
IV. Conclusions on Trend Directions
The current price trend is oscillating (with a bearish bias). The rationale for this judgment is that the changes in the 5-day, 10-day, and 20-day moving averages compared to the previous day are not entirely consistent, and do not meet the criteria for a clear upward or downward trend. Therefore, the overall trend is oscillating, with a structural bias towards being bearish.
Five, Spatial Reference
The price ranges for styrene-butadiene rubber in different periods in China are as follows:
3-month cycle: Level 5 (high), with limited upside potential.
60-day cycle: Level 4 (mid-to-high range)
1 year cycle: Tier 4 (upper-middle)
Overall, prices are in a relatively high range, with insufficient momentum to move higher and some pressure for a pullback.

VII. Fundamental Analysis Reference
Cost side: The international crude oil market has been fluctuating at high levels, with upstream butadiene and styrene prices remaining in the mid-to-high range, providing some cost support for styrene-butadiene rubber.
Demand side: Downstream buyers remain wary of higher-priced supplies, with inquiries largely driven by immediate needs and overall purchasing sentiment remaining subdued.
Imports and Exports: In September 2026, China imported a total of 588,000 tons of natural and synthetic rubber (including latex), a decrease of 20.8% compared to the same period in 2025.
