Thermal Coal Tops 1,000 Yuan Again as Winter Stockpiling Begins

Thermal coal, the fuel burned in power stations to keep lights on and homes warm, has pushed back above 1,000 yuan (about $140) a tonne in China for the first time in three years, according to a report in the Securities Daily carried by several financial news outlets on Monday. The move reflects two forces meeting at once: utilities building up stockpiles ahead of winter, and supply that remains tight.

Coal is still a pillar of China’s electricity system, and the approach of the heating season is a familiar trigger for restocking. Power companies typically lift purchases in the autumn so that inventories are comfortable before demand peaks in the coldest months. This year, that seasonal pull has run into constraints on the supply side, pushing prices through the symbolic 1,000-yuan mark.

“Costs in the coal industry are relatively stable, so a rise in coal prices directly improves the profit expectations of coal companies and supports better results,” Yuan Huaming, general manager of Guangdong Huahui Chuangfu Investment Management, told the Securities Daily. In other words, when the price of the commodity rises, much of the gain flows to the bottom line of miners whose operating costs change little.

The effect is already visible in corporate results. The report notes that in the first half of the year, about 80 percent of listed thermal coal companies reported year-on-year improvements in performance, helped by coal prices that have been trending higher through 2026. With prices rising further in the third quarter, those profits are expected to thicken again.

For investors, the story is a reminder of how sensitive China’s coal equities are to the commodity cycle. Coal miners have often been treated as high-dividend, cash-generative holdings, and stronger prices can support both earnings and payouts. But the same cyclicality cuts both ways: a mild winter, a swift rebuild in supply or weaker industrial demand could cool the market quickly.

The price signal also carries wider implications for the power system. Higher coal costs feed into the cost of generating electricity, and utilities watch the fuel price closely when negotiating tariffs and managing margins. At the same time, China continues to add wind, solar and nuclear capacity at a rapid clip, gradually reducing the share of coal in the generation mix over the long term, even as it remains the backbone for now.

Analysts quoted in the report expect the near-term market to stay firm, with winter demand and supply tightness keeping prices elevated. Whether the 1,000-yuan level holds will depend on weather, hydropower output and how quickly mines can raise production. For now, the return of four-digit coal prices is a small but telling marker of a commodity cycle turning warmer as the northern hemisphere heads into winter.
