After the Shanxi coal mine accident, the risk of coal supply contraction has risen, and coal prices have short-term upside elasticity

Overview

This report focuses on the potential impact on China's coal industry output and prices following the major gas explosion accident at the Lu'an Shenyu coal mine in Changzhi, Shanxi Province on 2026-05-22. The report notes that after the accident, multiple coal mines in Shanxi entered safety inspection shutdowns, affecting a large scale of capacity and mainly concentrated in coking coal. Goldman Sachs does not directly judge the timing of production resumption, but believes China's coal supply faces contraction risk in the coming months, and coal prices may gain upside support from tighter safety regulation.

Core views

The core views include: first, post-accident safety inspection shutdowns involve 125mnt of annualized raw coal capacity, of which about 80mnt is expected to remain offline for at least one month or has no resumption plan yet, meaning the scale of supply disruption cannot be ignored. Second, the shutdown impact corresponds almost entirely to coking coal, equivalent to about 60mnt of annualized saleable coal capacity, exceeding 10% of the domestic coking coal market, so the coking coal supply shock is more direct. Third, industry fundamentals were already improving, with rising coal chemical demand, declining imports, and early power plant restocking in May, while thermal coal spot prices have risen counter-seasonally since the Spring Festival. Fourth, if coal prices continue to rise, coal stocks have earnings elasticity, with Chinacoal showing the highest earnings sensitivity to a 10% coal price increase.

Analysis framework

The report uses an event-driven supply-demand analysis framework: it first reviews the Shanxi coal mine accident and the subsequent scale of safety inspection shutdowns, then uses Mysteel data to quantify the number of affected mines, annualized capacity, and potential offline duration; it then compares the historical price reaction following multiple coal mine accidents and the three-year workplace safety campaign in 2H23; finally, through coal price sensitivity analysis, it assesses the earnings elasticity of coal stocks such as Shenhua, Chinacoal, and Yankuang.

Methodology notes

• Industry supply-demand analysisPost-accident supply disruption assessment

  Assess coal supply risk through accidents, safety inspections, suspended capacity, and the pace of production resumption.

  The report treats the annualized capacity, suspension duration, and coal-type mix of post-accident suspended mines as the key inputs for judging coal price upside risk.

• Historical analogyComparison with coal mine accidents and safety regulation in 2H23

  Use price performance during earlier periods of tighter safety regulation after coal mine accidents as a reference.

  The report mentions that after accidents in 2H23, the three-year workplace safety campaign led to output declines in major coal-producing regions, during which domestic thermal coal prices rose 27% and coking coal prices rose 30%.

• Earnings sensitivityEarnings elasticity analysis for a 10% coal price increase

  Estimate the impact of changes in domestic spot coal prices on coal company earnings.

  Goldman Sachs estimates that every 10% increase in domestic spot coal prices would affect earnings by +4.1%, +7.8%, and +4.0% for Shenhua, Chinacoal, and Yankuang, respectively.

Asset mapping & comparison

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

• China coal sector

  The core industry covered by the report, with a focus on post-accident output and price impacts.

  Strengths

  The supply side is constrained by safety inspections, while the demand side is supported by coal chemical demand, declining imports, and power plant restocking.

  Weaknesses

  The pace of production resumption is uncertain, and the persistence of supply disruption is still unclear.

  Comparison

  Compared with normal seasonality, thermal coal prices have risen counter-seasonally since the Spring Festival, indicating that fundamentals had already improved.

  Risks

  If suspended mines resume production quickly or demand weakens, coal price upside may be limited.

• Coking coal

  The coal type most directly affected by the accident-related shutdowns.

  Strengths

  Affected saleable coal capacity is about 60mnt/year, exceeding 10% of the domestic coking coal market, implying a significant supply shock.

  Weaknesses

  The report does not judge the specific timing of production resumption, and price elasticity depends on the actual offline duration.

  Comparison

  Compared with thermal coal, the report states that almost all affected coal capacity is related to coking coal.

  Risks

  Faster-than-expected production resumption, weak steel-chain demand, or increased import substitution.

• Thermal coal

  Indirectly affected by industry safety regulation and improving fundamentals.

  Strengths

  Coal chemical demand is rising, imports are declining, and power plants are restocking early; spot prices have risen from Rmb718/t to Rmb835/t.

  Weaknesses

  The direct accident impact is mainly on coking coal, so the supply shock to thermal coal is relatively indirect.

  Comparison

  During a similar safety regulation period in 2H23, domestic thermal coal prices rose 27%.

  Risks

  Summer demand disappoints, imports recover, price-stabilizing policy measures are introduced, or inventories rise.

• China Coal Energy A/H

  The key coal stock for which the report maintains a Buy rating.

  Strengths

  Goldman Sachs estimates that for every 10% increase in domestic spot coal prices, Chinacoal earnings rise 7.8%, higher than the peer sample.

  Weaknesses

  Earnings are highly correlated with coal prices; if supply disruption fades, earnings elasticity could work in reverse.

  Comparison

  Earnings sensitivity is higher than Shenhua's 4.1% and Yankuang's 4.0%.

  Risks

  Coal price decline, faster-than-expected production resumption, A/H-share valuation volatility, and policy regulation.

• Shenhua and Yankuang

  Peer companies used for comparison of coal price earnings sensitivity.

  Strengths

  Rising coal prices also contribute positively to earnings.

  Weaknesses

  The report's earnings elasticity for a 10% coal price increase is lower than Chinacoal's.

  Comparison

  Earnings elasticity for Shenhua and Yankuang is 4.1% and 4.0%, respectively, versus 7.8% for Chinacoal.

  Risks

  If the rise in coal prices is not sustained, earnings improvement may be smaller than estimated.

Key data

• Accident time and location2026-05-22, Lu'an Shenyu coal mine, Changzhi City, Shanxi ProvinceThe accident was a major gas explosion that caused significant casualties and triggered safety inspection shutdowns at related coal mines.
• Capacity of the accident mine1.2mnt/yearLu'an Shenyu coal mine is operated by Shanxi Tongzhou Group, and the coal type is hard coking coal.
• Current scale of safety inspection shutdowns125mnt annualized raw coal capacity; 113 coal minesData source is Mysteel as cited in the report.
• Coal mines that have resumed production16Some mines previously shut down due to accident-related factors have restarted.
• Output with longer or uncertain suspension durationNearly 80mnt, about 64% of suspended outputExpected to remain offline for at least one month or still without a clear resumption timeline.
• Affected saleable coking coal capacityAbout 60mnt/yearEquivalent to more than 10% of the domestic coking coal market.
• Historical price performance after tighter regulation in 2023Thermal coal +27%; coking coal +30%The report uses this as a historical reference for stronger workplace safety regulation after coal mine accidents.

• Impact of a 10% coal price increase on earningsShenhua +4.1%; Chinacoal +7.8%; Yankuang +4.0%Chinacoal has the highest earnings elasticity.

Impact & implications

If post-accident safety inspections continue, the contraction in coking coal supply could be more direct, while thermal coal may also benefit from improving industry fundamentals and a higher risk premium. At the equity level, rising coal prices have a positive effect on coal company earnings, with Chinacoal's earnings sensitivity higher than Shenhua's and Yankuang's, so the report maintains its Buy view on Chinacoal A/H. However, this judgment is highly dependent on the pace of production resumption, regulatory intensity, and demand sustainability.

Risks

• Suspended coal mines in Shanxi resume production faster than expected, weakening the supply shock.
• Safety inspection intensity is below market expectations, and coal output does not decline materially.
• Coal chemical, steel, or power demand weakens, reducing support for coal prices.
• Coal imports recover, offsetting the impact of domestic supply contraction.
• Price-stabilizing policies or output-boosting measures limit coal price upside.
• Coal mine safety accidents and regulatory events are sudden in nature, making timing and scope of impact difficult to predict.
• A substantial amount of chart body data is missing from the input content, so some charts can only be judged based on title information.

What to watch

• The production resumption progress of the 113 coal mines in Shanxi under safety inspection shutdowns.
• The proportion of the roughly 80mnt of suspended output that remains actually offline for more than one month.
• Mysteel's subsequent updates on suspended coal mine capacity and resumption timing.
• Whether coking coal and thermal coal spot prices continue to rise.
• Coal chemical operating rates, steel demand, and the pace of power plant restocking.
• Whether China's coal imports continue to stay below 2025 levels.
• Subsequent rating, target price, and earnings forecast revisions for Chinacoal A/H.
