This analysis, based on the original mean difference method, adds new dimensions of upstream and downstream industry chain linkage and supply-demand validation to provide a more comprehensive interpretation of the MIBK spot price trend and operational logic on August 31, 2026, offering references for companies in the industry chain in China.
I. Table of Mean Difference Changes
| Indicator | Today's Value (2026.08.31) | Yesterday's Value (2026.08.30) | Direction of Change |
|---|---|---|---|
| 5-day Average Deviation (D5) | 140.00 | 90.00 | + |
| 10-day Average Deviation (D10) | 155.00 | 163.34 | - |
| 20-day Average Deviation (D20) | 230.84 | 213.33 | + |
II. Signal State Determination
The current three average difference change direction combinations are (+, -, +), which belongs to a stagnation warning (bearish) signal.
III. Conclusion on Trend Direction
The current MIBK price trend in China is oscillating (with a bearish bias).
Reason: The directions of the three differences compared to the previous day are not completely consistent, which does not meet the criteria for a clear upward/downward trend. This is a stagnation warning signal within a fluctuation range, and the short-term trend is biased towards the downside.
IV. Positional Spatial Reference
The 60-day period price is at the 5th level (high), with limited short-term upside potential.
Prices over 3-month and 1-year periods are in the third tier (median), with relatively balanced upside and downside potential in the medium to long term.
Five, Supplementary Linked Analysis
Cost support changes: Isopropanol is the core upstream raw material for MIBK. On August 31, 2026, the 5-day average difference of isopropanol prices in China decreased compared to the previous day. Currently, the 60-day and 3-month cycle prices are both at high levels, and there is insufficient short-term upward momentum, leading to a slight loosening of cost support for MIBK.
Demand-side validation: Currently, procurement in downstream sectors such as dewaxing agents, extractants, and antioxidants under MIBK has been relatively slow, with purchasing primarily driven by essential needs. The supply-demand dynamic is marginally loose, further supporting the rationale behind the bearish signal of stagnation and price resistance.
