HSBC flags fuel shortage risk in the mining supply chain, with sea freight the least transparent and highest-risk link

Overview

This report discusses the potential impact of Middle East conflict and a closure of the Strait of Hormuz on petroleum product transport, and assesses how fuel shortages could spread through mining production and export supply chains. HSBC believes that mines may have enough short-term fuel inventory to support about four weeks of operations, but supply becomes highly uncertain after that; if global supply is hit by a shock of close to 20% and the burden is shared evenly across all consumers, mine diesel consumption could also face about 20% pressure.

Core views

The core view is that the risks to mine-site operations and off-site logistics are not the same. On-site operations have more of a short-term buffer, but open-pit or bulk mines that rely heavily on diesel are more sensitive; rail that is owned by the mining company and backed by inventory or electrification faces lower near-term risk; third-party trucking, coal rail, shipping exports and marine fuel supply are more likely to become bottlenecks. The report particularly emphasizes that the sea freight link is the least transparent, and if key hubs such as Singapore lack Middle East feedstock and marine fuel output falls, miners' export capacity and freight rates could be affected.

Analysis framework

The report decomposes risk by supply chain segment, including mine supply, rail, trucking and helicopters, ships and aircraft, and combines this with differences in commodity type, region, mining method and logistics ownership structure to judge impact intensity. The focus is not a single oil price forecast, but rather the constraints that fuel availability, third-party logistics dependence, transport mode and inventory management place on mining continuity.

Methodology notes

• Supply chain risk decompositionSegment-by-segment assessment from mine to export

  Split the mining chain into mine operations, rail, trucks, sea freight and air transport, and assess how fuel shortages transmit through each link.

  This approach helps distinguish between short-term diesel inventory risk at mine sites and the risks in off-site third-party logistics, port marine fuel and aviation fuel, avoiding a simplistic view that all miners have the same exposure.

• Operational sensitivity analysisComparison of diesel dependence and mining method

  Different mining methods rely to different degrees on diesel, electricity and labor, so their exposure to fuel shortages differs.

  The report argues that traditional underground mines in South Africa rely more on labor and electricity and less on diesel, while bulk miners such as iron ore and coal have higher diesel consumption in both mine operations and the supply chain, implying greater potential impact.

  Upside or downside relative to the current share price is used to support Buy, Hold or Reduce ratings.

  The report discloses HSBC's rating definitions, but this thematic research does not change ratings or target prices.

Asset mapping & comparison

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

• Bulk mines: iron ore and coal

  High diesel consumption and transport-chain exposure

  Strengths

  Large miners with their own rail or electrified lines face lower short-term interruption risk.

  Weaknesses

  Diesel consumption is higher in mine operations and the supply chain, and coal miners usually do not own rail while trains are typically diesel-powered.

  Comparison

  Compared with traditional underground mines in South Africa, bulk mines are more sensitive to diesel and transport continuity.

  Risks

  Diesel shortages, insufficient rail fuel supply, slower export pace, higher freight rates.

• South African manganese and potential chromium

  Exposure to third-party trucking

  Strengths

  Some covered companies, such as ARM and South32, primarily use rail to export manganese products.

  Weaknesses

  Some industry products depend on trucking companies to move material from mine to port, with fuel supply managed by third parties.

  Comparison

  Control is weaker than for miners with their own rail.

  Risks

  Truck fuel shortages, disruptions in mine-to-port transport, inventory buildup.

• Copper mines

  Exposure to mine diesel and some trucking

  Strengths

  Mine-site water in Chile typically comes from desalination plants, and power is often supplied by renewables.

  Weaknesses

  Mines still consume diesel, and some operations in Chile and Peru need trucks to transport concentrate to port.

  Comparison

  The risk sits between that of large mines with dedicated rail and commodities that rely heavily on third-party trucking.

  Risks

  Lower diesel supply, restricted regional trucking, delayed port deliveries.

• Precious metals miners

  Exposure to air export

  Strengths

  Low-volume, high-value cargo can be switched relatively flexibly between cargo flights and passenger flights.

  Weaknesses

  Regional jet fuel availability may still impose constraints.

  Comparison

  Compared with bulk commodity sea freight exports, precious metals have smaller volumes and more alternative flight options.

  Risks

  Fewer cargo flights, jet fuel shortages, higher air freight costs.

• Sibanye – SSW SJ

  Company disclosed in the report

  Strengths

  The report notes that traditional underground mines in South Africa use relatively little diesel, and the disclosure section lists the rating as Buy.

  Weaknesses

  PGM producers usually have structural differences across traditional, hybrid and mechanized mining, so actual diesel exposure needs to be judged by asset mix.

  Comparison

  Compared with miners with a higher share of mechanized operations, exposure in traditional underground mines may be lower.

  Risks

  Regional fuel shortages, higher air or logistics costs, PGM supply chain disruptions.

Key data

• Fuel inventory buffer at mine sitesAbout four weeksThe report believes mining operations may have enough fuel inventory in the near term, but supply becomes uncertain after that.
• Potential global supply shock assumptionNearly 20%If the shock is shared evenly across all consumers, mine diesel consumption could face about a 20% impact.
• Most critical risk linkSea freight and marine fuelThe report considers this link the least transparent and the one with the highest potential risk over the coming months.
• Mining method less affectedTraditional underground mines in South AfricaThese mines rely more on labor and electricity and use relatively less diesel.
• Example of company disclosureSibanye – SSW SJ, Buy, CMP ZAR52.73This information comes from the company list disclosed in the report and does not indicate a rating change in this report.
• Market data date2026-04-01 closeThe disclosure page states that, unless otherwise noted, market data are as of the close on 2026-04-01.

Impact & implications

If fuel shortages persist, the impact may first appear in export chains and third-party logistics rather than immediate mine shutdowns. For investment judgment, it is important to distinguish whether a miner owns its rail, relies on third-party trucks or port marine fuel, exports mainly by sea, and how high the commodity value is relative to transport mode. In the near term, miners with their own rail, electrified transport or lower diesel intensity should be more resilient; in the medium term, marine fuel shortages could lift freight rates, reduce vessel availability and affect the export pace of some mineral products.

Risks

• Middle East conflict and a closure of the Strait of Hormuz continue to affect crude oil and petroleum product transport.
• After the four-week fuel inventory buffer runs out, the ability to keep mines operating normally may become uncertain.
• Insufficient marine fuel supply could reduce available vessels and push up freight rates.
• Opaque fuel management for third-party trucks, rail and ports may make it difficult for miners to respond in time.
• Actual impacts vary widely by region, commodity and mining method, so they cannot be simply extrapolated linearly.

What to watch

• Whether key marine fuel hubs such as Singapore experience a shortage of Middle East feedstock.
• Updates from miners on days of diesel inventory, fuel procurement and logistics contracts.
• Truck and rail transport status for South African manganese, chromium and coal, and for copper mines in Chile and Peru.
• Changes in sea freight rates, vessel availability and port fuel supply.
• Jet fuel supply and scheduling of precious metals export flights.
• Whether miners reduce short-term fuel consumption through higher-grade mining or by adjusting mining sequences.
