Thermal Coal Market Cools Temporarily as Pre-Peak Season Enters a Pause

Market Enters a Pause After Rapid Gains
In June, the thermal coal market—previously supported by tighter mine safety inspections and pre-summer stockpiling—has entered a short-term cooling phase. The upward momentum in both pithead and port prices has moderated, with the market shifting from a unilateral rally to a wait-and-see consolidation pattern.
Driven by high port inventories, strengthening hydropower output during the flood season, and weakening acceptance of high-priced coal, spot prices have stabilized in the near term. However, continued strict safety inspections and expectations of extreme summer heat still provide downside support, limiting the scope for meaningful price corrections. Overall, the market is characterized by a balance between supply and demand forces, with limited directional momentum.

Diverging Trends Between Production Areas and Ports
Price trends have diverged between production regions and ports this week. In the production areas, the previous speculative rally is gradually unwinding, with several mines in Shaanxi and Inner Mongolia lowering prices slightly. The market has shifted from broad-based gains to overall stability with localized softening.
In contrast, port prices remain relatively firm and continue to edge higher. High delivery costs and strong pre-summer restocking expectations have kept traders supportive of prices. As of June 4, the “CCTD-Spot Index” stood at RMB 863/t (5500 kcal), RMB 775/t (5000 kcal), and RMB 676/t (4500 kcal), up RMB 2/t, RMB 2/t, and RMB 1/t, respectively.

Hydropower Rise and Summer Demand Still Provide Structural Support
Southern China has entered the peak rainy season, with above-average inflows in major river basins such as the Yangtze and Lancang rivers. Reservoir levels in hydropower-rich provinces including Sichuan, Yunnan, Hunan, and Hubei have improved, supporting higher hydropower generation and temporarily suppressing thermal coal demand.
However, the broader summer demand outlook remains strong. The National Climate Center has warned of a high probability of a moderate El Niño event this summer, increasing the likelihood of extreme heat across China. Peak electricity loads are expected to reach new highs, with thermal power likely to play a key balancing role in eastern and southern China, providing a solid demand floor for coal prices.

Tight Safety Controls and Weak Import Substitution Limit Supply Growth
Domestic supply remains constrained by persistently strict safety inspections. June marks China’s national “Work Safety Month,” and follow-up inspections after the Shanxi Qinyuan mining incident have led to normalized high-intensity regulatory oversight in major producing regions including Shanxi, Shaanxi, and Inner Mongolia. Production flexibility remains limited, and significant short-term output growth is unlikely.
On the import side, substitution support is weakening. International coal prices remain elevated, Indonesian export quotas are tightening future cargo availability, and Australian coal continues to face cost disadvantages upon arrival in China. As a result, import supply provides only limited incremental relief to the domestic market.

High Port Inventories Limit Upside, but Spot Market Remains Resilient
As of June 4, total inventory across major Bohai Rim ports reached 28.65 million tonnes, continuing a gradual upward trend. Qinhuangdao Port inventories are approaching the 7 million-tonne level, also high by historical standards, exerting clear pressure on spot prices.
However, rail transport priority for long-term contract supply has structurally increased the share of contract coal at ports, while reducing the proportion of market coal. This has limited liquidity in the spot segment, helping maintain relatively strong price resilience despite high inventories.

Outlook: Range-Bound Consolidation Ahead of Peak Season
Overall, the thermal coal market has entered a consolidation phase. While upward momentum has paused, underlying fundamentals remain supportive. In the short term, prices are expected to remain range-bound with mild fluctuations. Limited downside risk persists due to tight supply conditions, while peak summer demand expectations continue to provide a firm price floor.
