Douyin Says Fuel Prices Will Rise Again—Will They on September 11?

The Middle East crisis has heightened jet fuel supply risks, causing Asian airlines to brace for sky-high jet fuel prices. Jet fuel, which accounts for a significant portion of airline operating costs, has seen prices more than double since the US-Israeli war on Iran started. This indicates a strong upward pressure on fuel prices. Although there have been fluctuations, with prices falling 6.7 percent in the week ending April 17 after hitting over $200 earlier in the month, the overall trend has been upward due to supply concerns. Given the ongoing conflict and its impact on fuel supply, it is likely that the crude rebound will dominate, leading to a final increase in fuel prices on September 11.

With five of ten working days completed in the pricing cycle that opened August 31 (after the NDRC's August 28 hike of 375 yuan/ton for gasoline and 360 yuan/ton for diesel), the accumulated crude change rate is decisively positive and still rising. JLC data cited on September 4 put the reference crude average at $90.73/bbl, the change rate at 3.44%, and the implied adjustment at +175 yuan/ton; a separate September 4 estimate put it at +210 yuan/ton. The driver is a sharp geopolitical shock: US strikes on Iranian military facilities at Larak Island on August 30 and Iranian missile retaliation on August 31 pushed Brent from roughly $86 pre-strike to $90-96, adding a Strait of Hormuz risk premium. The bearish view circulating in late August (the Yicai and Sina pieces of August 28-29, which expected a decline on easing US-Iran tensions) has been overtaken by events, and the rolling estimate has flipped four sessions in a row: -80 yuan/ton on September 1, +100 on September 2, +140 on September 3, +175 on September 4. Because 3.44% corresponds to 175 yuan/ton, the 50 yuan/ton statutory threshold sits near a 1% change rate, implying a base basket around $87.7/bbl. For the September 11 announcement to be 'no adjustment,' the remaining five sessions would have to average below roughly $86.5 -- about 9% under current spot -- and to produce a cut they would have to average below roughly $83, a 13% collapse. Absent an immediate and total unwinding of the war premium, neither is plausible. Mechanically, the low-price data from the first half of the cycle is still rolling out and higher prices rolling in, which biases the final figure upward rather than downward. Crude above $80/bbl does trigger the mechanism's graduated processing-margin deduction, which damps the size of the increase, but it does not change its direction and only fully suppresses increases above $130/bbl. I therefore expect the NDRC to announce an increase in gasoline and diesel price ceilings effective 24:00 on September 11, 2026. The Douyin hot-list framing happens to be directionally right, but the reason is the post-August 30 conflict escalation, not social-media sentiment.

FINAL_INCREASE is the clear favorite as of the cutoff. On pricing day five, Jinlianchuang estimated a 3.44% crude-price change and a RMB 175-per-tonne increase—well above the RMB 50 no-adjustment threshold. The estimate had progressed from a first-day decrease to increases of RMB 5, 100, 140 and 175 per tonne, showing that the crude rebound had already overwhelmed the early decline. WTI then settled at $91.48 on September 4, while Zhuochuang expected next week's WTI and Brent averages around $90 and $95 and saw no near-term easing in the US-Iran confrontation. Those levels should preserve a positive ten-day average unless crude suffers a swift, sustained collapse.

As of the 2026-09-05 cutoff, contemporaneous Chinese pricing trackers and media consistently project a retail fuel-price INCREASE for the NDRC's 11 September 2026 window. The 28 August window already lifted gasoline/diesel by 375/360 yuan per tonne; in the current cycle a crude rebound driven by US-Iran and Strait-of-Hormuz tensions pushed WTI above $90 and Brent near $96 (six-week highs), flipping an early 'cut' expectation into projected rises of roughly +140 to +220 yuan/tonne as of 3-4 September. That is far above the ~50 yuan/tonne adjustment threshold, so FINAL_INCREASE is the most probable outcome.

As of September 4, 2026, halfway through the 10-working-day pricing cycle for the September 11 adjustment, international crude oil prices (Brent above $95/bbl, WTI above $91/bbl) have surged due to Middle East geopolitical tensions and supply concerns. Energy consulting agencies such as Jinlianchuang and Zhuochuang Information calculate that the crude rate of change has reached +3.44% to +3.95%, corresponding to a projected domestic price increase of 160 to 210 yuan per ton for gasoline and diesel. Because this comfortably exceeds the National Development and Reform Commission's (NDRC) 50 yuan/ton threshold, the crude rebound dominates early cycle declines, making FINAL_INCREASE the most likely outcome.

Researching contemporaneous NDRC and market estimates for the September 11, 2026 China refined-fuel window before assigning a stance.

Rolling estimates for the September 11, 2026 pricing window flipped from an initial ~80 yuan/ton cut (Aug 31, change rate -1.54%) to a +175 yuan/ton increase by the 5th working day (Sept 4, change rate +3.44%), after the Sept 1 US-Iran escalation around the Strait of Hormuz sent WTI up 5.2% and Brent 4.6%. Crude has held those gains through the Sept 4 settle (WTI $91.48, Brent $96.28). With the projected adjustment more than triple the 50 yuan/ton threshold and five high-price days already baked into the 10-day average, only a sharp, sustained crude collapse could produce no adjustment or a cut, so the NDRC is most likely to raise gasoline and diesel ceilings on September 11.

As of September 5, 2026, the most likely outcome for China's domestic fuel price adjustment on September 11, 2026, is a **FINAL_INCREASE**. This assessment is based on the following evidence and analysis: 1. **Recent NDRC Adjustments and Mechanism**: The National Development and Reform Commission (NDRC) adjusts domestic gasoline and diesel prices every 10 working days based on the weighted average of international crude oil prices. If the change in the average price is less than 50 yuan per ton, no adjustment is made. The most recent adjustment on August 28, 2026, raised gasoline and diesel prices by 375 yuan and 360 yuan per ton, respectively, reflecting a rebound in international crude oil prices PortugalJKFxYtAP). 2. **International Crude Oil Price Trends**: As of early September 2026, international crude oil prices have remained volatile but generally elevated. Brent crude oil prices were reported at $93.03 per barrel on August 31, 2026, and $91.20 per barrel on September 4, 2026, indicating a sustained upward trend. This rebound is driven by geopolitical tensions, particularly in the Middle East, and supply disruptions, which have kept prices above the levels that would trigger a price freeze or cap under the NDRC's mechanism PortugallaLppWW3,3gbi0iYj,zj4aew6M). 3. **Adjustment Threshold and Recent Trends**: The NDRC's mechanism includes a 50 yuan per ton threshold for adjustments. The August 28 adjustment confirms that the change in the crude oil basket was sufficient to trigger an increase, and there is no evidence of a significant decline in international prices that would offset this trend. The recent rebound in crude prices, combined with the August 28 increase, suggests that the change for the September 11 window will likely exceed the 50 yuan threshold, resulting in a **FINAL_INCREASE** PortugalJKFxYtAP). 4. **Historical Context and Social Stability**: While the NDRC has previously intervened to cap or freeze price adjustments for social stability reasons, there is no indication of such intervention at this time. The August 28 adjustment was a moderate increase, suggesting that the NDRC is allowing the pricing mechanism to function as designed, without extraordinary measures PortugalJKFxYtAP). 5. **Uncertainties**: The primary uncertainty remains the volatility of international crude oil prices, which could shift rapidly due to geopolitical developments or unexpected supply disruptions. However, as of September 5, 2026, the trend supports a continued rebound, making a **FINAL_INCREASE** the most probable outcome.

I select FINAL_INCREASE. The latest pre-cutoff evidence has shifted from early downside expectations to a substantial positive estimate: by September 4, the reported crude-linked change was about +3.44%, implying roughly 175 yuan per ton higher domestic gasoline and diesel prices. The official mechanism adjusts on ten-working-day averages, so the early declines are increasingly outweighed by the subsequent crude rebound. The estimate is well above the 50-yuan no-adjustment threshold. [web:18][web:23][web:15]

As of September 4-5, 2026, multiple authoritative institutions report that the crude oil change rate for the current pricing cycle has turned positive and is widening. By the 5th working day (Sept 4), the change rate reached approximately 3.44%, corresponding to an expected price increase of 175 yuan/ton. This exceeds the 50 yuan/ton threshold required for an adjustment. With five working days remaining, the momentum of rising international crude prices (WTI above $91, Brent above $95) suggests the final average will remain well above the threshold, making a price increase the most likely outcome.

As of September 5, 2026, the latest available pre-cutoff market data shows that intensifying Middle East geopolitical tensions and falling U.S. crude inventories have driven crude oil prices to a strong upward trajectory, which has overridden earlier mild downward expectations and makes a final fuel price increase the most probable outcome for the September 11 pricing window.

As of the Sept 5 cutoff, the Sept 11 window has flipped from an early-cycle decrease expectation to a clear increase. NDRC confirmed the Aug 28 window raised gasoline +375 and diesel +360 yuan/ton, with the next window set for Sept 11 24:00. The new 10-working-day cycle opened bearish (analysts cited hoped-for US-Iran detente), but crude then surged on US-Iran military escalation and Hormuz disruption: by Sept 3 the crude change rate was +2.01% to +2.68% (about +100 to +140 yuan/ton), far above the +50 yuan/ton adjustment threshold, and the gap was widening. With the first half of the cycle locked in high and a geopolitical risk premium intact (no de-escalation in sight, WTI/Brent forecast near $90/$95), the crude rebound dominates and an increase is the base case.

China's refined-fuel prices are set by the NDRC every 10 working days based on the moving average of international crude. For the September 11, 2026 window, the available reporting cycle shows estimates swinging as crude fell early in the window and then rebounded into the close. Late-window crude strength typically pushes the rolling average back above the 50 yuan/ton adjustment threshold, so an announced increase is the most likely outcome, though the margin appears thin, leaving a meaningful chance of a 'stranded' (no-adjustment) outcome.

As of September 4, 2026, the 5th working day of the pricing cycle shows a 3.44% crude oil change rate with an estimated increase of 175 yuan/ton, far exceeding the 50 yuan/ton adjustment threshold, making a price increase on September 11 highly probable.
