(Bloomberg) — Chinese coal prices are creeping higher as the weather becomes more unpredictable and the government expands its supervision of mines in a bid to prevent accidents and curb overproduction.

Although the market for China’s mainstay fuel remains weak by historical standards, official scrutiny has introduced a new prop for prices. “The government’s ‘anti-involution’ drive to cut overcapacity with measures like safety checks could become the norm,” Bloomberg Intelligence said in a note.

Next week’s Fourth Plenum in Beijing has put the sector on high alert to avoid incidents that could overshadow the policy meeting. In addition, the government has instructed high-ranking inspectors to fan out across the country from November for an “annual safety exam” across industries that should amplify efforts to improve mining practices. Shanxi, a key coal-mining province, got a special mention in the official notice for its worrisome safety record.

Benchmark thermal coal prices at the port of Qinhuangdao rose to 723 yuan ($101) a ton on Wednesday, according to the China Coal Transportation and Distribution Association. They had troughed at a four-year low of 610 yuan a ton in June, the result of massive oversupply that Beijing’s anti-involution campaign is designed to reverse.

Flood Impact

Shanxi and neighboring Shaanxi are two coal hubs already contending with floods that are likely to curtail supply in coming months, Li Xuegang, an analyst at the association, said at a briefing on Wednesday. Imports could slow as well, now that restocking for the winter is almost done, he said.

Set against tighter supply is the abundance of hydropower caused by heavy rains, which is likely to crimp the need for coal. A slowing economy is also capping consumption of the fuel.

The scrambled climate is playing heavily into the demand side of the equation. Unusually high temperatures in central and eastern China have kept air conditioners humming, while chilly rains in the north have forced several cities to turn on the heating about a month earlier than normal. Both should mean more coal use.

The various factors leave the market biased toward more increases, but judging levels is becoming trickier.

“We expect a mild gain, but how much exactly the price will be? You will get different answers.” said Li.

On the Wire

Copper’s surge is spurring Chinese smelters to step up shipments abroad, lured by near-record prices in London while higher costs deter buyers at home.

US Treasury Secretary Scott Bessent dangled the possibility of extending a pause of import duties on Chinese goods for longer than three months if China halts its plan for strict new export controls on rare-earth elements. Finance chiefs from the Group of Seven industrial nations will consider a joint response to discourage China’s planned move to control the global supply of rare earths.

China’s retaliatory port fees on US-linked vessels are reverberating through markets for American crude. The levies are exposing oil shipping companies to hefty fees, making them scramble for relevant paperwork, and contributing to delays, cancellations and spiraling freight costs.

The UK slapped sanctions on Russia’s biggest oil producers and two Chinese energy firms that deal with Moscow as London seeks to intensify pressure on the Kremlin over the war in Ukraine.

South African and Chinese municipalities agreed a deal to construct a $35 million solar-panel assembly plant, a boost to Pretoria’s plans to attract international investment needed to promote district-level development.
