Conflict could put mining supply chains under fuel shortage pressure, with the highest risk in shipping

Overview

This report examines whether mining supply chains would be hit by fuel shortages under scenarios involving Middle East conflict, disruptions to oil transport, and a closure of the Strait of Hormuz. HSBC's core view is that mine operations may have fuel inventory buffers in the near term, but supply visibility deteriorates after four weeks; external supply-chain links may come under pressure earlier, especially marine fuel, third-party trucking, and some jet fuel.

Core views

The report argues that risks at mine operations themselves are relatively manageable in the short term, but they vary significantly by mining method, fuel intensity, reliance on outsourced logistics, and export route. Traditional underground mines in South Africa are labor- and power-intensive and use relatively little diesel, so they are less affected; bulk miners such as iron ore and coal producers have higher diesel consumption and logistics fuel demand, and thus greater potential impact. BHP and Rio own and operate their own rail networks, so near-term supply disruption risk is lower; coal, manganese, chromite, and some copper transport operations that rely on third-party rail or trucking deserve closer attention. Shipping is seen as the biggest risk over the next several months because marine fuel supply is opaque.

Analysis framework

The report breaks mining supply-chain risk down by link, including diesel inventories at mine sites and mining methods, rail, trucks and helicopters, ships, and aircraft transport, and combines different commodity and regional logistics patterns to assess potential exposure. The focus is not on financial model adjustments, but on identifying the ways fuel shortages could transmit to miners through operations, export capacity, and freight rates.

Methodology notes

• Supply chain risk decompositionAssess fuel exposure by logistics link

  Split the mining supply chain into mine operations, rail, trucking, sea freight, and air transport, and assess fuel inventory, third-party dependence, and substitutability separately for each.

  This framework helps distinguish inventory risk that is short-term and controllable at the mine site from bottlenecks in external logistics links that are more opaque and may appear earlier.

• Mining method comparisonDiesel intensity analysis

  Different mining methods have different dependence on diesel, labor, and power, so the impact of fuel shortages varies accordingly.

  Traditional underground mines in South Africa are more labor- and power-intensive and use less diesel; mechanized and bulk open-pit or high-transport-intensity businesses are more sensitive to diesel.

• Scenario assumptionScenario in which nearly 20% of global supply is affected

  If the shock to nearly 20% of global supply is shared evenly across all consumers, mine diesel consumption could face an impact of about 20%.

  The report uses this scenario to highlight that supply uncertainty rises after four weeks, while also noting that miners can reduce fuel consumption in the short term by mining higher-grade ore or adjusting mining sequences.

Asset mapping & comparison

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

• Bulk miners: iron ore and coal

  Diesel consumption and supply-chain fuel use are high, so the potential impact is larger.

  Strengths

  Some large miners own their own rail networks or have stronger logistics management capabilities.

  Weaknesses

  Mining operations and export chains are fuel-intensive, so if diesel or marine fuel tightens, costs and shipments may come under pressure.

  Comparison

  Compared with traditional underground mines in South Africa, bulk miners are more sensitive to diesel and long-haul logistics.

  Risks

  Lower diesel supply, disruption to diesel rail, reduced vessel availability, and higher freight rates.

• Traditional underground mines in South Africa: Harmony, Sibanye, Impala

  They are relatively less directly exposed to fuel shortages.

  Strengths

  Traditional underground mines rely more on labor and power and use less diesel.

  Weaknesses

  Some PGM producers still include mechanized or hybrid mining methods, so exposure is not zero.

  Comparison

  Compared with more mechanized mines, traditional underground mines are less diesel-sensitive.

  Risks

  If external logistics, jet fuel, or regional fuel supply is constrained, transport and exports could still be affected.

• South African manganese and potential chromite mines

  They are more likely to be affected by onshore supply-chain pressure.

  Strengths

  ARM and South32 use rail to a relatively large extent in manganese exports.

  Weaknesses

  Some industry products rely on trucking companies from mine to port, and fuel supply is managed by third parties.

  Comparison

  Compared with miners that own their own rail networks, links that depend on third-party trucking are less controllable.

  Risks

  Third-party truck diesel shortages, port shipping delays, and higher transport rates.

• Copper miners: business exposure in Chile and Peru

  There is diesel consumption at the mine site, and some concentrate transport depends on pipelines and trucks.

  Strengths

  Water at Chilean mine sites is usually supplied by desalination plants, and some sites are powered by renewable energy.

  Weaknesses

  Some mines and transport routes still require trucking, and fuel shortages could affect concentrate delivery to port.

  Comparison

  Compared with traditional underground mines in South Africa, copper mining may be more fuel-dependent on the transport side; compared with bulk miners, exposure depends on the specific logistics structure of each site.

  Risks

  Truck fuel shortages, cross-regional logistics delays, and rising port transport costs.

• BHP and Rio's own rail networks

  The risk of near-term rail supply disruption is lower.

  Strengths

  The companies own and operate their own rail networks, can typically manage diesel inventories themselves, and some lines are electrified.

  Weaknesses

  They may still be affected by external fuel supply, port, and shipping links.

  Comparison

  Compared with miners that rely on third-party rail, the short-term risk of rail disruption is lower.

  Risks

  Fuel replenishment uncertainty after four weeks, marine fuel shortages, and insufficient export vessels.

• Precious metals miners

  Low-volume, high-value cargo is typically exported by freight or passenger flights.

  Strengths

  If cargo flights are reduced, the report believes it may be relatively easy to shift to passenger flights.

  Weaknesses

  Aviation fuel supply is regionally uneven, and regional shortages would still affect flights and costs.

  Comparison

  Compared with bulk minerals, precious metals are less dependent on sea freight but more sensitive to the availability of jet fuel.

  Risks

  Regional jet fuel shortages, fewer cargo flights, and higher air freight rates.

• Example stock mentionedSibanye – SSW SJ, Buy, CMP ZAR52.73The report lists company information, but it is not overall a single-company rating change report.

Impact & implications

If fuel supply tightness persists, miners' risk may shift gradually from on-site operations to export capacity and transportation costs. In the short term, companies with inventories, their own rail networks, or electrified logistics will be more resilient; companies that rely on third-party trucking, diesel rail, or opaque marine fuel supply will be more likely to face transport bottlenecks, higher costs, or export delays. For investors, the key question is whether fuel shortages evolve from a temporary logistics disturbance into a material shock that affects output, sales, and margins.

Risks

• Middle East oil transport is disrupted by the conflict and a closure of the Strait of Hormuz, leading to insufficient diesel, marine fuel, or jet fuel supply.
• After the four-week inventory buffer, there is significant uncertainty over whether mine operations can maintain normal production.
• Marine fuel shortages could reduce the number of available vessels and push up sea freight rates, affecting mineral exports.
• If third-party trucking and rail operators cannot secure their own fuel supply, miners' onshore logistics may be disrupted.
• The impact is highly dependent on region, commodity type, and mining method, and cannot be simply extrapolated to all miners.
• Economic sanctions and regional trading restrictions may further affect related securities or commodity investment activity.

What to watch

• Middle East oil transport and access through the Strait of Hormuz.
• Whether key marine fuel hubs such as Singapore experience supply tightness due to reduced feedstock from the Middle East.
• Whether mine diesel inventories can be replenished after four weeks.
• The operation of third-party trucking and diesel rail in South African manganese, chromite, and coal transport.
• Whether companies such as BHP, Rio, Kumba, and ARM that own rail networks or electrified rail maintain logistics stability.
• The impact of jet fuel supply on precious metals export flights and freight rates.
• Whether companies reduce fuel consumption by mining higher-grade ore or adjusting mining sequences.
