China's Coking Coal Futures Surge ~46% in August, Posting Largest Monthly Gain Since Contract Inception
nashnova research
Dalian coking coal futures rose roughly 46% in August — the largest single-month gain since the contract listed in 2013. A deadly Shanxi mine explosion triggered mass safety shutdowns while Mongolian supply tightened on environmental curbs, squeezing both ends of supply at once.
How rare is a 46% monthly surge?
By the August 31 midday session, the Dalian benchmark contract stood at 1,721.5 yuan/tonne, up sharply from 1,181 yuan/tonne on July 31.
This means → coking coal gained roughly 540 yuan per tonne in a single month, eclipsing the ~38% record set just one month earlier in July.
In plain terms = in 12 years of trading, this contract has never moved this fast in any single month.
What triggered the spike?
The driver is supply, not a demand boom. In May, Shanxi province suffered China's worst coal-mine explosion since 2009.
Shanxi accounts for roughly half of China's coking coal output. Regulators launched sweeping safety inspections; multiple mining districts were forced to halt production, and the output gap kept widening.
This means → China's largest coking-coal region went into sudden, large-scale curtailment — available supply shrank fast, and the gap pushed prices higher.
Can imports fill the gap?
Mongolia is a key backup source, but Mysteel reports that stricter environmental inspections on open-pit coal stockpiles have also cut Mongolian shipments to China.
Domestic output down, imports tightening — supply is being squeezed on both ends. China has had to ramp up metallurgical-coal imports from other channels to cover the shortfall.
In plain terms = the home mines stopped and the neighbor's mines are rationing too. When both taps tighten at the same time, prices have nowhere to go but up.
Are other steelmaking commodities following?
Singapore iron-ore futures edged up 0.5% to $99 per tonne, on track for the first monthly gain since April.
Shanghai steel futures also rose in tandem. This reflects coking coal's price signal — as a core steelmaking input — rippling through the broader ferrous supply chain.
The key variable ahead: when Shanxi's safety inspections conclude and whether mines can restart quickly — that will determine if coking coal keeps climbing or peaks here.
