Coking coal futures in Dalian hit their daily down limit, tumbling 6.2% to 1,340.50 yuan a ton, the biggest intraday drop since August 2025, Bloomberg News reported on Wednesday.
The decline followed a report that Shaanxi authorities issued a notice urging miners to maintain a stable supply through the summer peak demand period, the newswire said.
Prices had rallied to near two-year highs after a deadly accident in neighboring Shanxi last month raised safety and supply concerns, the publication said.
According to Mysteel data, around 70 mines in Shanxi with a capacity of 85 million tons have since resumed production, while 65 mines remain suspended, the report said.
