supply chain risks and outlook for mining industry

The 2026 Iran war has intensified geopolitical risk across global mining and metals markets, extending the impact of regional conflict far beyond the Middle East. Although the military confrontation is centred on Iran, Israel, and several Gulf countries, its implications for mining are being transmitted through higher energy prices, shipping disruption, rising insurance costs, and greater uncertainty across commodity supply chains. For the mining industry, the main concern is not only the risk of direct production loss in the region, but also the broader effect on processing costs, raw material flows, and global trade routes.

A key transmission channel is the Strait of Hormuz, one of the world’s most strategically important maritime chokepoints. Any disruption to flows through the Strait affects not only crude oil and petroleum products, but also the movement of industrial inputs and refined metals. As security risks in the corridor rise, mining companies are facing higher fuel bills, longer shipping times, tighter freight availability, and elevated marine insurance premiums. These pressures are feeding into operating costs across both upstream mining and downstream refining activities, particularly in commodity chains that are highly dependent on imported inputs or seaborne logistics.

The conflict is also reinforcing a structural challenge already facing the sector, mining supply chains remain highly exposed to concentrated trade routes and energy markets. In this environment, the industry is likely to see a stronger strategic push toward supply diversification, localised processing, renewable power integration, and lower diesel dependence. While the immediate market response has focused on oil price volatility, the more important medium-term consequence for mining could be the acceleration of investment in operational resilience.

Iran’s mining and metals sector is facing growing pressure from the combined effects of infrastructure disruption, power constraints, and export bottlenecks. Even where mine assets remain operational, interruptions to electricity supply and industrial support systems could reduce utilisation rates across energy-intensive activities such as copper smelting, steelmaking, and aluminium production. At the same time, the deterioration in regional shipping conditions is likely to affect export flows and delay the movement of processed metals into international markets.

The impact is more significant in refining and processing than in mine production alone. Smelters and refineries are highly sensitive to energy availability, imported feedstock, and uninterrupted logistics. As a result, any prolonged conflict in the region could weaken the reliability of processed metal supply, even if upstream extraction remains comparatively less affected. This distinction is important for global markets, as refined supply disruptions tend to have a faster effect on pricing, procurement decisions, and downstream manufacturing activity.

The effect of the war on iron ore markets is likely to be driven more by cost inflation than by direct supply loss. Iran is a notable iron ore producer, with output of 61 million tonnes (mt) in 2025 and a 3.8% share of global production according to the USGS, but the larger market implication lies in the conflict’s effect on fuel and freight economics. Iron ore mining is highly diesel-intensive, particularly in extraction, hauling, and transport, making the sector vulnerable to sustained increases in oil prices.

Higher fuel prices, coupled with shipping delays and insurance cost escalation linked to Hormuz-related disruption, are likely to lift operating expenditure for major iron ore miners. For producers with large-scale open-pit operations, this increases pressure on margins and strengthens the long-term case for greater electrification, renewable integration, and other cost-mitigation measures. In this sense, the conflict could reinforce an existing industry shift toward reducing exposure to diesel-based operating models.

The logistics backdrop also matters. The Strait of Hormuz handled an average of 20 million barrels per day of crude oil and petroleum products in 2025, accounting for roughly 25% of global seaborne oil trade. Any prolonged disruption in the corridor would keep energy markets tight and increase transport costs across bulk commodity supply chains. In addition, rerouting shipments around longer maritime routes such as the Cape of Good Hope would extend transit times and delay the delivery of mining equipment, industrial materials, and consumables.

Aluminium is one of the metals most exposed to regional energy and logistics disruption. The Middle East accounts for around 9% of global aluminium production, with major producers in the UAE, Bahrain, Saudi Arabia, Qatar, Iran, Oman, and Egypt. According to the USGS, the UAE and Bahrain produced an estimated 2.7mt and 1.6mt of primary aluminium, respectively, in 2025. This makes the region an important supplier in the global aluminium value chain, particularly given the metal’s dependence on uninterrupted power and stable raw material inflows.

In Iran, aluminium production has already been under pressure from electricity shortages, gas supply constraints, and financial limitations. The country produced 552,200t of primary aluminium during the first 11 months of Iran’s 2025 financial year, down 5.2% from 582,200t in the same period of FY24. With an installed production capacity of around 650,000t per annum, the sector remains exposed to further downside if war-related disruptions deepen constraints on power, imported inputs, and industrial continuity.

More broadly, the conflict raises risks for aluminium smelters across the Middle East because the industry is highly dependent on stable imports of alumina and other inputs, as well as uninterrupted energy supply. Shipping disruption in the Strait of Hormuz could delay raw material inflows, increase freight and insurance costs, and create operational inefficiencies in smelting activity. For regional producers, this points to tighter margins and a higher risk of temporary curtailments if supply chains remain constrained. For instance, Qatalum smelter in Qatar has initiated a phased shutdown of its aluminium smelter on 3 March 2026, to address safety and environmental risks, following a suspension of its essential natural gas supply. Following this, on 15 March 2026, Aluminium Bahrain (Alba) is conducting a controlled, phased shutdown of reduction lines 1, 2, and 3 to manage raw material inventory and operational stability amid regional shipping disruptions. This strategic move focuses resources on core production lines to ensure a safe, efficient operation and a potential future restart.

The war also has important implications for nickel, lead, and zinc through the sulphur market. Sulphur is a critical input for sulphuric acid production, which in turn is essential for processing and refining several base metals. Because sulphur is also a by-product of oil and gas refining, disruption across the Middle East can affect both production and trade availability, creating a secondary supply shock for mining and metals processing.

For zinc and lead, sulphuric acid is a key processing reagent used in refining. Tightness in sulphur supply would therefore increase refining costs and could constrain output where smelters are heavily dependent on imported acid or sulphur feedstock. For nickel, the implications are particularly significant in high-pressure acid leach (HPAL) operations, which require large volumes of sulphur to produce mixed hydroxide precipitate for electric vehicle battery supply chains.

Indonesia, the world’s largest nickel producer, is especially exposed because it imports around 75% of its sulphur requirements from the Middle East. This creates a clear transmission channel from regional conflict to the global battery metals market. If sulphur availability tightens materially, nickel processing costs could rise sharply, weakening the economics of HPAL projects and slowing the pace of supply growth. In turn, this could affect the affordability and availability of nickel units needed for the EV battery market.

The conflict is contributing to commodity price volatility, but the impact is likely to vary across metals depending on their exposure to energy, refining inputs, and trade routes. Copper and nickel are particularly vulnerable because their value chains rely on stable access to sulphur and energy-intensive refining systems. Aluminium is also exposed given the Middle East’s production role and the sector’s dependence on uninterrupted electricity and imported raw materials.

Beyond immediate price movements, the conflict is highlighting the strategic vulnerability of globally interconnected mineral supply chains. Metals cannot rely on the same transport flexibility as some energy markets, as they depend heavily on ship-based trade, port access, and specialised processing networks. This makes them more exposed to geopolitical bottlenecks and regional supply disruption. The result is likely to be a more risk-sensitive pricing environment, especially for metals linked to energy transition technologies and industrial manufacturing.

At the same time, the conflict may deepen the strategic importance of China within global mineral supply chains. As Western economies seek to reduce exposure to Middle Eastern oil and logistics risk, they may accelerate electrification and renewable deployment. However, that transition could also increase dependence on Chinese dominance in several critical mineral processing chains. This creates a policy and procurement challenge for consuming nations, which are seeking both energy security and mineral security at the same time.

The broader oil and gas disruption created by the conflict is also influencing industrial strategy in Asia. Countries facing fuel supply pressure are being forced to adjust energy consumption patterns, ration fuel use, and prioritise essential sectors. In the near term, some governments may turn back to coal and nuclear power to stabilise electricity supply and offset the loss of Middle Eastern fuel imports. This has implications for mining, as changes in the generation mix directly affect power-intensive commodity production and metal processing costs. In India and other Asian economies, higher petrol and diesel prices may also encourage faster interest in electric mobility and alternative energy systems. However, in markets where coal still

dominates the electricity mix, the transition may initially raise reliance on fossil fuel-based power generation even as vehicle electrification expands. For mining, this underlines a broader paradox: short-term conflict can increase dependence on conventional fuels, even while strengthening the long-term case for renewable energy, electrification, and domestic energy security.
