When coal prices move, the cost of electricity, cement, steel and many manufactured goods moves with them. For plants that burn coal directly, fuel is often the largest operating cost, so a sharp rise can wipe out margins within months. In 2026 coal prices rose strongly: Australian Newcastle coal went from an average of $108.40 per tonne in 2025 to $147.10 in September 2026, according to the World Bank.
This guide explains which industries are most exposed, what drives coal prices, and how buyers can manage the risk.
Which industries feel coal prices most
| Industry | How coal is used | Exposure |
|---|---|---|
| Power generation | Fuel for boilers | Very high: fuel is the main variable cost |
| Cement | Fuel for kilns | High: energy is a large share of production cost |
| Steel | Coking coal for coke; PCI coal | High: coal and coke are major inputs |
| Pulp, paper, chemicals, textiles | Fuel for industrial boilers | Medium to high |
| Energy-intensive manufacturing | Indirectly, through electricity prices | Varies with the local power mix |
What is driving coal prices in 2026
- Gas and oil prices. European gas reached $25.42 per MMBtu in September 2026, up from a 2025 average of $11.96, and Brent crude was $116.80 a barrel. When gas is expensive, more power plants switch to coal, pushing coal prices up.
- Lower Indonesian supply. Indonesia’s production fell to 790 Mt in 2025 and the IEA expects exports to fall again in 2026.
- Supply disruptions. Colombia’s Cerrejón mine declared force majeure on 1 June 2026.
- Chinese and Indian demand. Their buying decisions move the seaborne market more than anything else.
- Freight and currency. Shipping costs and the US dollar change delivered prices.
Indonesian 4,200 kcal/kg coal rose from about $45 to about $66 per tonne FOB between the start of 2026 and the end of August, according to the IEA. See Indonesian coal price per ton and coal in the global energy market.
How price swings reach your business
- Operating costs rise immediately for spot buyers, and at the next price reset for contract buyers.
- Selling prices may not keep up, squeezing margins, especially in competitive markets.
- Working capital increases, because the same tonnage costs more to buy and hold.
- Planning becomes harder when budgets are set on prices that no longer hold.
How to manage coal price risk
1. Mix contract and spot buying
Term contracts with an agreed price formula give stability. Keeping part of your needs on spot lets you benefit when prices fall.
2. Choose the right index and formula
Agree which index your price follows, such as ICI for Indonesian coal or Newcastle for Australian coal, and how often it resets.
3. Buy on energy, not tonnes
Compare offers on delivered cost per unit of energy. A cheaper, lower-energy coal is not always cheaper in use. See how to assess coal quality.
4. Diversify origins
A second supplier or origin reduces the impact of a disruption at one mine or country.
5. Use efficiency to cut volume
Every point of efficiency gained reduces how much coal you buy. See improving efficiency in coal-fired power plants.
6. Consider hedging
Large buyers can use coal futures and swaps to fix part of their cost. This needs expertise and suitable financial arrangements.

Frequently asked questions
Why did coal prices rise in 2026?
Higher gas and oil prices, lower Indonesian exports and supply disruptions such as the Cerrejón force majeure all pushed prices up.
Which industries are most affected by coal prices?
Power generation, cement and steel, where coal is a major input, followed by manufacturers that rely on coal-fired electricity.
How can a company protect itself from coal price swings?
By combining term contracts and spot purchases, agreeing a clear price index, diversifying origins, improving efficiency and, for large buyers, hedging.
What is the Newcastle coal price?
The benchmark price for Australian high-energy thermal coal. The World Bank recorded $147.10 per tonne in September 2026.
Do coal prices follow gas prices?
Often, yes. When gas becomes expensive, power generators switch to coal where they can, which raises coal demand and prices.
Is Indonesian coal cheaper than Australian coal?
Per tonne, usually yes, because it has less energy. Compare delivered cost per unit of energy to see which is better value for your plant.
