Indonesian coal import arbitrage window remains open; China's thermal coal imports may stay elevated

Overview

This report focuses on weekly price, import, and arbitrage conditions in China's coal market. The core conclusion is that thermal coal prices moved higher month over month, while coking coal prices remained broadly resilient; China's thermal coal imports rebounded significantly in June, with Indonesia as the largest source country, and the Indonesian coal import arbitrage window remained open in July, potentially driving imports to stay at a relatively high level that month.

Core views

The report's main views include three points. First, domestic thermal coal prices rose modestly, with Qinhuangdao 5500, BSPI, CCI 5500, and Shanxi Datong 5800 mine-mouth prices all recording month-over-month increases. Second, seaborne thermal coal prices also edged up, with NEWC prices rising 0.8% month over month. Third, coking coal prices were relatively stable, with domestic Liulin No.4 mine-mouth and FOR prices flat, while QLD prices fell 1.3% month over month to US$230/ton. On imports, China's thermal coal imports rose 38.3% month over month in June, Indonesia's share reached 53.8%, and shipments increased 34.9% month over month, indicating that import arbitrage and improving expectations for power plant demand had a clear impact on trade flows.

Analysis framework

The report uses a weekly tracking framework, comparing month-over-month changes in domestic thermal coal, seaborne coal, and coking coal prices, and combines this with a country-level breakdown of China's thermal coal imports to assess the import arbitrage window and potential import volume trends. It focuses on price spreads, import profits, expectations for power plant consumption, and changes in shipments from source countries.

Methodology notes

• Commodity price trackingWeekly coal price month-over-month monitoring

  Observe the relative strength of thermal coal and coking coal markets through price indicators such as Qinhuangdao 5500, BSPI, CCI 5500, mine-mouth prices, NEWC, and QLD.

  Month-over-month price increases usually reflect short-term supply-demand improvement or cost support; observing different pricing benchmarks at the same time helps distinguish changes across domestic ports, mine-mouth, and seaborne markets.

• Trade arbitrage analysisImport arbitrage window

  Compare the profit margin of imported coal versus domestic coal prices after related costs to determine whether imports are economical.

  The report notes that the Indonesian coal import arbitrage window remained open in July, which may support China's thermal coal imports staying elevated that month.

• Import structure analysisSource-country breakdown

  Break down China's thermal coal imports by source country to identify the main supply contributors.

  In June, Indonesia accounted for 53.8% of China's total thermal coal imports, and Indonesian shipments rose 34.9% month over month, indicating that Indonesian coal was the key source behind this round of import growth.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Chinese coal producers

  Higher thermal coal prices and resilient coking coal support revenue and earnings, but rising imports may cap domestic price elasticity.

  Strengths

  Major domestic coal price indicators rose month over month, while coking coal prices remained stable.

  Weaknesses

  The opening of the import arbitrage window may bring increased overseas coal supply.

  Comparison

  Compared with a purely domestic supply-demand-driven market, the economics of Indonesian coal imports are currently an important external variable affecting domestic prices.

  Risks

  If import volumes remain elevated and demand falls short of expectations, domestic coal prices may decline.

• Indonesian thermal coal export chain

  Indonesia was the largest source of China's thermal coal imports in June, and the open import arbitrage window is favorable for Indonesian coal shipments to China.

  Strengths

  In June, Indonesia accounted for 53.8% of China's thermal coal imports, and shipments rose 34.9% month over month.

  Weaknesses

  Dependent on China's import arbitrage, exchange rates, freight rates, and domestic-versus-overseas price spreads.

  Comparison

  Compared with other source countries, Indonesia made the largest contribution to China's thermal coal imports that month.

  Risks

  If the arbitrage window closes or Chinese power plant demand weakens, shipment growth may slow.

• Chinese power and fuel-consuming enterprises

  Higher coal imports may improve fuel supply and ease procurement cost pressure.

  Strengths

  The open import window expands available sources of supply.

  Weaknesses

  Overall coal prices are still rising, so lower costs are not guaranteed.

  Comparison

  Downstream enterprises are more affected by fuel procurement prices and inventory management than by changes in import volume alone.

  Risks

  Summer electricity demand, weather, and policy factors may amplify fuel price volatility.

Impact & implications

For the coal sector, short-term price resilience and import arbitrage coexist: month-over-month price increases support domestic coal producers' revenue, but the continued opening of the import window means overseas coal supply may increase, creating some downward pressure on subsequent domestic coal prices. For power producers and downstream users, improved imported coal supply helps ease fuel cost pressure. From an investment perspective, it is necessary to track import volumes, port inventories, power plant daily burn, and whether domestic prices can hold up under a high-import environment.

Risks

• Sustained high imported coal volumes may pressure domestic coal prices and the earnings elasticity of coal producers.
• If improvement in power plant consumption falls short of expectations, higher imports may lead to inventory accumulation.
• Changes in seaborne coal prices, freight rates, exchange rates, and policy may cause the import arbitrage window to narrow quickly or close.
• The report does not provide new company earnings forecasts, target prices, or explicit rating changes, so single-stock investment conclusions need to be combined with subsequent full research.
• Morgan Stanley discloses business relationships or potential conflicts of interest with some covered companies, and investors should treat this research as one factor in decision-making rather than the sole basis.

What to watch

• Whether China's thermal coal imports remain elevated in July.
• Whether Indonesian coal import arbitrage profits stay positive.
• Whether domestic thermal coal prices such as Qinhuangdao 5500, CCI 5500, and BSPI can remain resilient under high import levels.
• Changes in power plant daily burn, inventories, and peak summer demand.
• Whether coking coal prices continue to hold steady, especially the trends of domestic Liulin No.4, FOR, and overseas QLD prices.
• Subsequent updates to ratings, target prices, or earnings forecasts for covered coal companies.
