August 13th, according to news,
Recent consecutive gains in the international crude oil market have driven up diesel prices at refineries in many regions of China. The differential indicators show a clear upward trend in diesel prices, which are currently at a high level within a 1-year cycle and in the high range for 60-day and 3-month cycles. The upside potential needs to be cautious of high-level pressure, and subsequent attention should be paid to the impact of international crude oil trends on diesel prices.
Diesel Spot Price Market Analysis Daily Report (August 12, 2026)
I. Table of Mean Difference Changes
| Average Difference Type | Today's Value (2026-08-12) | Yesterday's Value (2026-08-11) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 123.40 | 85.41 | + |
| 10-day Average Difference (D10) | 73.46 | 47.20 | + |
| 20-day Average Difference (D20) | 18.53 | 9.20 | + |
II. Signal State Determination
The three mean differences all showed the same direction of change as the previous day and were all positive, indicating a clear upward signal.
III. Conclusion on Trend Direction
Diesel prices are showing a clear upward trend. Reasons: The 5-day, 10-day, and 20-day average differences have all increased positively compared to yesterday, with all three moving in the same direction, meeting the criteria for a clear upward trend according to the average difference method. Additionally, international crude oil prices have been rising continuously, and the diesel quotes from refineries in Northeast and Northwest China are maintained at 7500-7600 CNY per ton, with both upstream and downstream fundamentals supporting the price increase.
IV. Positional Spatial Reference
Diesel prices are at a medium-to-high level (Tier 4) over the one-year cycle, and at a high level (Tier 5) over the 60-day and three-month cycles. The current high-range suggests limited room for short-term price increases, so caution is advised regarding the risk of a pullback after prices surge. Meanwhile, the medium-to-high position over the one-year cycle indicates that prices still enjoy some support in the medium term, though close attention should be paid to the sustainability of international crude oil trends.
