China's coal safety supervision may tighten further, with divergent energy price performance
BofA's weekly report tracks China's energy sector and notes that, after the coal mine accident in Qinyuan, Shanxi, mine suspensions and expanded inspections are disrupting coal supply in the short term; at the same time, oil prices are falling, refining margins are easing, and natural gas and energy-storage prices are diverging.
- On May 22, a gas explosion at a coal mine in Qinyuan County, Changzhi, Shanxi, killed at least 82 people. In Qinyuan, 25 coal mines with a combined capacity of 25.6mntpa were suspended, and the number of suspended coking coal mines in Shanxi rose to 73, with a combined capacity of 78.9mntpa.
- For the week ending May 22, 2026, QHD 5,500kcal coal prices were flat WoW at RMB834/t, NEWC 6,000K coal prices rose 0.3% WoW to US$132.05/t, and Liulin No. 4 coking coal fell 1.2% WoW to RMB1,620/t.
- Brent and WTI oil prices fell 5.2% and 8.4% WoW to US$103.5/b and US$96.6/b, respectively, widening the WTI discount to Brent to US$6.9/b.
- China's May refining profit, calculated using a one-month lag in crude oil prices, was US$11.3/b, down from US$31.5/b in April; utilization at Shandong independent refineries fell to 52.5%, while state-owned refineries remained at 67%.
- In energy storage, China's BESS awarded capacity in April was 32.6GWh, down 35% MoM and 8% YoY; 50/100/280/314Ah cell prices edged higher.
Report interpretation
Overview
This report is BofA Securities' weekly update on China's energy sector, covering coal, oil, natural gas, energy storage, refining, and chemicals. The report emphasizes that, after the Qinyuan coal mine accident in Shanxi, safety supervision may tighten, with coal supply temporarily affected by suspensions and inspections; it also tracks changes in international oil and gas prices, energy-storage bid awards and cell prices, refining margins, and petrochemical spreads.
Core views
The core view is: on coal, a major safety incident has triggered regional suspensions and grid-style inspections, which may tighten coking coal supply in the short term, but most suspended mines outside Qinyuan are expected to restart after 3 to 5 days of self-inspection; on oil and gas, Brent and WTI fell sharply as the market swung between geopolitical risks and negotiation progress; on refining, margins fell materially from April and utilization at independent refineries declined; on energy storage, cell prices rose slightly but BESS awarded capacity eased MoM; on chemicals, naphtha, ethylene, propylene, LLDPE, and PP prices generally weakened, with some spreads softening.
Analysis framework
The report uses a weekly high-frequency industry tracking approach, combining coal mine accidents and policy supervision events, coal prices and inventories, international oil and gas prices, refinery utilization, refining margins, energy-storage tender awards and cell prices, and chemical prices and spreads to assess short-term supply-demand and price changes across China's energy value chain.
Methodology notes
Observe marginal industry changes through prices, inventories, utilization rates, import volumes, and tender data.
The report mainly compares week-on-week, year-on-year, and month-on-month data, such as coal prices, port inventories, power plant inventories, oil and gas prices, refinery utilization, BESS awarded capacity, and chemical prices.
Major accidents may trigger safety inspections and suspensions, thereby affecting short-term coal supply.
Twenty-five coal mines in Qinyuan were suspended, and the number of suspended coking coal mines in Shanxi rose to 73, leading the report to judge that coal safety supervision is likely to tighten further.
Assess industry margin pressure through changes in feedstock and downstream product prices.
The report compares naphtha, ethylene, propylene, LLDPE, PP, and related spreads, and tracks changes in refining margins from April to May.
Asset mapping & comparison

- China coal and coking coal value chaindirectly related
- Strengths
- Safety inspections and suspensions may tighten supply in the short term and support coal prices.

Impact & implications
Coal safety incidents and tighter regulation may create a short-term supply disruption for coking coal in Shanxi, supporting expectations for tighter supply, but the actual impact depends on how quickly the suspended mines restart. The oil, gas, and chemical chains are more about lower input costs, falling prices, and margin compression, and the retreat in refining margins from elevated levels warrants attention. In energy storage, although cell prices edged higher, BESS awarded capacity declined WoW, suggesting that demand pace and pricing competition still need monitoring.
Risks
- A faster-than-expected restart of coal mines could weaken support for coal prices.
- A wider-than-expected or longer-than-expected safety inspection campaign could cause a larger supply shock.
- International oil prices are highly volatile in the short term, affected by U.S.-Iran talks, Russian export issues, inventories, and shipping factors.
- Falling refining and chemical prices may compress value-chain margins.
- Declining energy-storage tender volume and pricing competition may hurt industry profitability.
- This report is a sector weekly and does not constitute a rating on any single stock; investors should make decisions based on their own risk tolerance and additional information.
