China's raw coal output decreased in April 2026 as seasonal maintenance and steady operation overpowered a price rally in the off-peak demand period, yet the volume stayed at relatively elevated levels.

The country churned out 385.63 million tonnes of raw coal in the month, down 1% from a year earlier and 12.5% from March, data from the National Bureau of Statistics showed.

Historically, April and July are China's low-output months for coal. In April, the drop typically reflects weak demand during the seasonal lull and softer pricing, while July's trough comes amid heavy rainfall in the main flood season.

This April, however, coal prices defied the usual slack season trend and stayed firm. The fact that output fell month on month may point to two factors.

Coal supply-demand tension has been steadily easing in China. Mines in key producing regions increasingly operate at their approved capacity in a balanced manner, with little change in output. Even when market conditions shift, production cannot immediately track prices.

Major producing provinces and state-owned enterprises largely stick to pre-set annual targets, leaving limited room for short-term adjustment unless policy directives change decisively.

Second, mines routinely schedule maintenance during the traditional off-peak season when supply pressure is low. This, combined with regularized safety and environmental inspections, cemented the seasonal pattern of output.

Looking ahead, May's raw coal output is expected to stabilize at a relatively high level, rebounding from April. An interplay of more frequent extreme weather, the amplifying effect of the El Nino phenomenon, the approaching summer peak months, government requirements for power plants to build stockpiles, and reduced coal imports plays a part.

For the first four months this year, cumulative raw coal output reached 1.58 billion tonnes, edging down 0.1% from the same period a year earlier, compared with a 0.1% uptick recorded in the first quarter.
