August 18 news
On August 18, 2026, the BDO market trend clearly rose. The reason is that the three directions of the average difference method were consistently positive, along with fundamental support. For example, Shaanxi Heima's facility plans to undergo maintenance for 45 days in late August, leading to a reduction in supply. On August 17, the market quotes were stronger compared to previous levels. The bidding price of Inner Mongolia Sanwei was higher than the starting bid, and the reduction in supply due to plant maintenance supported the upward trend in prices.
1. Average Difference Change Table
| Average Difference Type | Today's Value (2026-08-17) | Yesterday's Value (2026-08-16) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 15.00 | 0.00 | + |

2. Signal Status Judgment
The trend is clear (upward), and the three moving averages all showed positive changes compared to the previous day.
3. Trend Direction Conclusion
Clearly Upward Trend. Reason: According to the mean difference method, the mean differences over 5-day, 10-day, and 20-day periods all showed the same direction of change as yesterday—positive—thus meeting the criteria for a clearly upward trend. From a fundamental perspective, Shaanxi Heimao’s 60,000-ton/year BDO plant is scheduled for a 45-day maintenance shutdown in late August, and Changqing Petroleum’s 100,000-ton BDO plant is undergoing catalyst replacement with no spot quotes available, reinforcing expectations of supply contraction. On August 17, China’s BDO market quotations were relatively strong compared to the previous period; Inner Mongolia Sanwei’s auction sales of BDO achieved prices higher than the starting bid, indicating robust market transactions. Multiple factors are jointly supporting the upward price trend.
