China Thermal Coal Prices Hit Three-Year High as Multiple Factors Constrain Supply
nashnova research
China's power-plant coal benchmark broke ¥1,000/tonne for the first time in nearly three years, up roughly 25% since mid-July. Domestic output cuts, shrinking imports, and surging alternative-fuel costs have converged ahead of winter heating season — and no price ceiling is in sight.
How much has the price moved — and why does it matter?
The power-plant coal benchmark hit ¥1,004/tonne on Monday — the first four-digit reading in two years. This means → the floor cost of generating electricity across China just stepped up, squeezing utility margins.
Coal still accounts for roughly half of China's power mix. In plain terms = when coal gets expensive, half the country's electricity gets expensive — from factory power bills to residential heating.
The rally concentrated in barely two months: ~25% since mid-July, faster than the market had expected.
Why is domestic output falling — and when might safety controls ease?
China's domestic coal output dropped more than 3% year-on-year in January–August. The trigger: a fatal mine accident in Shanxi province in May, after which regulators sharply tightened safety oversight.
The market had expected Shanxi to restore roughly 31 million tonnes of annualised capacity by year-end, but local coal-industry sources say approvals are running well behind schedule.
This reflects the upcoming Communist Party congress later this month. In plain terms = "no incidents" outranks "more output" on regulators' priority list, leaving little room for a near-term relaxation.
Where is the transport bottleneck?
China's main coal-haulage rail corridor is undergoing a three-week maintenance window expected to last until October 26.
This means → even where mines have coal to ship, the rail link to power plants is physically constrained — adding a logistics premium on top of the supply squeeze.
What has gone wrong on the import side?
Indonesia — China's largest offshore thermal-coal supplier — has seen shipments drop sharply this year. Two reasons: Jakarta deliberately cut output to lift prices and boost fiscal revenue; and El Niño–linked drought lowered river levels in key mining regions, limiting barge capacity.
In plain terms = Indonesia wants to sell at higher prices, and the weather is simultaneously blocking coal from reaching its ports — both forces cut the volume available to Chinese buyers.
Can natural gas step in? Why is that path blocked too?
Liquefied natural gas (LNG — natural gas chilled into liquid form for shipping) has also surged in price this year.
Middle East conflict has disrupted Qatari LNG exports through the Strait of Hormuz, tightening supply and driving up costs. This means → the usual fallback logic — "if coal is too expensive, burn gas" — has broken down, forcing power plants to keep chasing coal.
Where is the price turning point — and which variables should we watch?
Winter heating season is approaching; seasonal demand recovery will keep upward pressure on prices.
The inflection point hinges on three variables: ① when safety-review approvals in Shanxi and other key regions accelerate; ② how quickly Indonesian exports normalise; ③ whether the LNG supply crunch eases.
In plain terms = three taps have been tightened at the same time — until at least one loosens, coal prices have little room to fall.
