This monitoring data is as of November 2, 2026. Based on the method of mean difference and the fundamental analysis of the spot market, the current phthalic anhydride price in China is in a high range over the past year, showing a strong consolidation pattern in the short term. The increase in upstream raw material costs, the recovery of downstream plasticizer demand, and low inventory levels provide strong support for the price. However, due to the restriction of the high range, the potential for further significant increases is limited.
I. Table of Finite Differences
| Mean Difference Indicator | Value on November 2, 2026 | Value on November 1, 2026 | Direction of Change |
|---|---|---|---|
| 5-Day Mean Difference (D5) | 0 | 0 | No Change |
| 10-Day Mean Difference (D10) | 38.33 | 50 | - |
| 20-Day Mean Difference (D20) | 19.17 | 29.16 | - |
II. Signal State Determination
The current signal indicates strong consolidation (biased bullish).
III. Conclusion on Trend Direction
The current phthalic anhydride price trend in China is oscillating with a bullish bias, for the following reasons: all three moving averages are currently non-negative, indicating that prices are still in an upward momentum channel in the short to medium term. Only the short-term moving average has flattened, and the medium to long-term moving averages have slightly declined, but there is no clear signal of a downturn. Since the directions of the three are not completely consistent, the market is judged to be in an oscillating pattern, overall favoring a bullish trend.
IV. Position Space Reference
Phthalic anhydride 60-day, 3-month, and 1-year cycle prices are all at high levels, corresponding to the 5th tier in a 5-tier position classification (the highest 20% range within the cycle), with limited room for further increases.

VI. Fundamental Support Validation
Cost Side: On November 2, crude oil prices fluctuated and rose, transmitting to the upstream raw material end; phthalic anhydride was quoted at RMB 10,450/ton, industrial naphthalene prices surged strongly, and cost support for phthalic anhydride increased significantly.
Supply and Demand: Phthalic anhydride producers have increased operating rates, spot supply remains stable, and overall inventories are low. Downstream plasticizer prices are rising, prompting manufacturers to boost equipment utilization; rigid demand continues to support phthalic anhydride consumption, and market sentiment remains strongly bullish.
