Coal Market September 2026: Prices Remain Elevated as Energy Demand Accelerates Ahead of Q4

Entering the first days of September 2026, the global energy market in general, and the coal market in particular, are witnessing highly notable developments. Following a volatile August, coal prices in the first week of September (from September 1 to September 6, 2026) have established a new price floor, significantly higher than the previous month's average. This article will delve into an analysis of actual data, identify causes, and assess the macroeconomic impacts currently influencing coal prices in Vietnam and worldwide.

1. Overview of Coal Price Movements in the First Week of September 2026

According to the latest data updated as of September 6, 2026, global coal prices are holding at 148.65 USD/mt, equivalent to approximately 3,872,853 VND/ton. Although the trend in recent days is considered relatively stable, looking at the broader picture, we see a clear growth trajectory.

Specifically, in the week from September 1 to September 6, coal prices shifted as follows:

• September 1, 2026: 144.85 USD/mt
• September 2 - 3, 2026: Increased to 146.60 USD/mt
• September 4 - 6, 2026: Reached the 148.65 USD/mt mark and remained stable there.

In less than a week, coal prices rose by 1.65 USD (equivalent to +1.12%). However, the more striking figure lies in the comparison between the two months. The average price for September is currently at 147.33 USD/mt, significantly higher than the 131.52 USD/mt average of August 2026. This indicates that the market has moved out of the low price range of the previous month and is establishing strong growth momentum heading toward the end of the year.

The fluctuation range over the past 30 days has been between 127.85 - 148.65 USD/mt. The fact that the current price is at the peak of this 30-day range shows that upward pressure remains present and shows no signs of a deep cooling off.

2. Analysis of Causes Behind Coal Price Fluctuations

The increase from an average of 131 USD in August to nearly 149 USD at the beginning of September is not coincidental. There are three main groups of causes leading to this volatility:

Fuel Stockpiling Demand for Winter in the Northern Hemisphere

September of each year is always the start of the energy stockpiling cycle in East Asian countries (China, Japan, South Korea) and Europe. Thermal power plants need to ensure sufficiently large inventories to meet the sudden surge in heating demand as winter approaches. The simultaneous return of energy "giants" to the purchasing market has driven spot prices higher.

Industrial Production Recovery in China and India

China and India continue to be the world's two largest coal consumers. In the third quarter of 2026, industrial production indices in these two countries showed a slight recovery, leading to increased electricity demand. In the context where renewable energy sources (such as hydropower) are affected by unfavorable weather conditions in some regions, coal-fired power still plays a foundational role, forcing businesses to increase imports.

Supply Constraints from Major Exporters

Several reports from Australia and Indonesia—the two leading coal exporters—show that production in August faced difficulties due to technical and logistics factors. In Australia, periodic maintenance at several large mines and export ports reduced the immediate supply to the market. In Indonesia, new regulations on resource management and domestic market obligations (DMO) have also tightened the volume of coal exported to international markets, indirectly pushing global coal prices up.

3. Macroeconomic Impacts on Coal Prices in the Current Period

Coal prices do not fluctuate based solely on supply and demand but are also deeply influenced by global macroeconomic factors.

Monetary Policy and the Strength of the USD

Coal is a commodity priced in USD. Therefore, any movement in the DXY index (measuring the strength of the USD) directly impacts the import costs of other countries, including Vietnam. In early September 2026, the US Federal Reserve's (Fed) maintenance of high interest rates to curb inflation has kept the USD strong. This causes coal prices calculated in local currency (VND) to rise, putting pressure on domestic electricity and steel production costs.

Natural Gas Prices and Energy Competition

Natural gas and coal are two interchangeable commodities in electricity production. When natural gas (LNG) prices tend to rise or supply is disrupted due to geopolitical tensions, power plants tend to switch to coal as a more economical alternative. The interconnection between oil, gas, and coal prices creates a chain reaction, keeping coal prices high while the overall energy market remains volatile.

Maritime Logistics Costs

Coal prices at the port of arrival (CIF price) are heavily influenced by dry bulk shipping rates. In September 2026, transport fuel prices remained high, coupled with a shortage of vessels on several key shipping routes, increasing the costs that make up the price of coal. This explains why, even if mine prices might be stable, the price delivered to the buyer remains at a high level.

4. The Coal Market in Vietnam: Existing Challenges

In Vietnam, the demand for coal for electricity production and heavy industry (cement, iron, and steel) is very high. With the current price of approximately 3,872,853 VND/ton, domestic businesses are facing the problem of rising input costs.

On the supply side: The Vietnam National Coal and Mineral Industries Group (TKV) and Dong Bac Corporation are making maximum efforts to increase domestic production. However, due to increasingly deep and difficult mining conditions, domestic coal production costs are also trending upward. To meet demand, Vietnam still has to import a large amount of coal from Australia and Indonesia.

On the demand side: Thermal power plants are entering a peak operation phase to ensure national energy security. The fact that global coal prices remain high (up more than 17 USD compared to the previous month's average) creates significant financial pressure for Vietnam Electricity (EVN) and independent power plant investors (IPP). If coal prices continue to remain at current high levels, adjustments to electricity prices or energy support policies may be considered in the coming period.

5. Outlook and Forecast for the Coming Period

Based on actual data and macroeconomic analysis, we offer some assessments for the coal market for the remainder of September 2026:

• Regarding prices: It is unlikely that coal prices will return to the 130 USD/mt level seen in August. Prices are forecast to fluctuate stably in the 145 - 155 USD/mt range. Any downward corrections, if they occur, will only be short-term due to the strong winter stockpiling demand.
• Regarding supply: Supply from Indonesia may improve toward the end of the month as export procedural hurdles are cleared, but this supply will be quickly absorbed by the Chinese market.
• Regarding risks: Unexpected geopolitical developments in conflict zones or extreme weather phenomena (La Niña) could disrupt the supply chain, causing sudden price shocks.

Advice for businesses: Businesses using coal as an input material need to closely monitor daily price lists and consider signing long-term contracts to lock in prices, avoiding the risk of spot price volatility during the year-end peak season. Optimizing coal combustion processes and seeking supplementary energy sources are also urgent solutions to reduce dependence on the volatile global market.

Conclusion

The coal market in the first week of September 2026 has shown a completely different face compared to the previous month. With a price of 148.65 USD/mt, the market is asserting its firm position in the context of high global energy demand. The combination of cyclical factors (winter), economic recovery, and logistics barriers has created a strong "push" for coal prices. In that context, Vietnam needs flexible strategies in balancing domestic mining and imports to ensure production stability and national energy security.
