The escalating conflict in the Middle East in early 2026 has evolved far beyond an energy-market crisis. What began as a regional geopolitical confrontation is now disrupting the global metals and mining industry, exposing vulnerabilities in supply chains that underpin everything from battery production and steelmaking to copper refining and aluminium smelting.
The closure of the Strait of Hormuz, damage to key industrial facilities, and the suspension of Persian Gulf operations by major shipping companies such as Maersk and Hapag-Lloyd have transformed a regional conflict into a global industrial challenge. As shipping routes tighten and critical raw material flows come under pressure, mining companies and metal producers worldwide are facing rising costs, supply uncertainties, and growing operational risks.
Critical Industrial Inputs Become the First Casualty
While market attention often focuses on major metals such as copper, aluminium, and nickel, the immediate impact of the crisis is being felt in the industrial inputs required to keep mines, smelters, and refineries operational.
The Middle East plays a crucial role in supplying global markets with sulphur, liquefied natural gas (LNG), petroleum products, and chemical feedstocks. These materials are essential for mineral processing, acid production, and energy-intensive industrial operations.
According to industry estimates, approximately 50% of the world’s seaborne sulphur supply is now exposed to disruption. This poses significant challenges for sectors dependent on sulphur-based processing, including nickel refining, fertilizer production, and copper extraction, where sulphuric acid is a critical component. The situation highlights how modern mining depends not only on mineral reserves but also on a complex network of supporting industrial materials that are often sourced from geopolitically sensitive regions.
Shipping and Fuel Markets Face Growing Pressure
The impact of the conflict is already visible across global transportation and fuel markets. Traffic through the Strait of Hormuz has fallen sharply, while more than 110 million barrels of oil are reportedly being held in floating storage. At the same time, regional producers have curtailed approximately 11 million barrels per day of oil output, tightening global energy supplies.
For mining companies, these developments translate directly into higher operating costs. Rising prices for diesel, marine bunker fuel, and transportation services are increasing expenses across the entire value chain, from mine-site haulage operations to concentrate exports and smelter deliveries. As logistics become more expensive and less predictable, producers are facing mounting pressure on margins and working capital requirements.
Aluminium Industry Among the Hardest Hit
The global aluminium market has emerged as one of the sectors most vulnerable to the ongoing disruption. Industry forecasts indicate that the Middle East could lose as much as 3.5 million tonnes of aluminium production in 2026, driven by power supply disruptions, operational shutdowns, labor unrest, and damage to industrial infrastructure.
Major facilities, including EGA Al Taweelah in the United Arab Emirates and ALBA in Bahrain, have been affected by the instability, reducing available supply in a market already facing growing demand from construction, transportation, and clean energy sectors.
The production losses are significant enough that alternative suppliers are unlikely to compensate quickly, even as producers in China and Indonesia attempt to increase output. As a result, global aluminium supply is now expected to decline by nearly 3% this year, creating upward pressure on prices and increasing concerns over future availability.
Steel Producers Battle Rising Costs
The steel industry is experiencing a different but equally significant set of challenges. Crude steel production across the Middle East dropped 33% in March, while output from Iranian steel mills plunged by approximately 55%. Disruptions affecting the movement of pellets and direct-reduced iron (DRI) have forced steelmakers to rely more heavily on alternative feedstocks, including scrap metal and billets.
This shift has intensified competition for available materials and pushed costs higher throughout the steelmaking sector. At the same time, rising prices for iron ore and metallurgical coal have increased production costs for blast furnace operators by nearly 10% since the beginning of the year. Electric arc furnace producers have also been affected, with scrap costs climbing between 10% and 15%. The result is a steel market facing both supply-side disruptions and growing cost inflation.
Copper Supply Faces an Indirect but Serious Threat
Unlike aluminium and steel, the global copper market has so far avoided major direct supply losses. The reduction in Iranian production and Gulf exports of semi-finished copper products accounts for less than 1% of global copper supply, limiting the immediate impact on overall availability. The greater risk lies elsewhere.
Copper production depends heavily on sulphuric acid, particularly in major mining regions such as the Democratic Republic of Congo (DRC). The DRC’s Copperbelt relies on Gulf suppliers for more than 90% of its acid imports, making it highly vulnerable to disruptions in Middle Eastern trade flows.
The consequences are already becoming evident. Spot sulphuric acid prices have surged to between US$1,000 and US$1,400 per tonne, significantly increasing operating costs for smaller producers and companies dependent on imported acid. If these conditions persist, production growth in some of the world’s most important copper regions could come under increasing pressure.
Nickel Industry Exposed Through Battery Supply Chains
The impact on the nickel sector extends well beyond traditional stainless-steel markets and reaches directly into the global battery industry. Indonesia’s rapidly expanding High-Pressure Acid Leach (HPAL) sector, which produces battery-grade nickel for electric vehicle applications, has become one of the largest consumers of sulphur worldwide.
More than 75% of Indonesia’s granular sulphur imports originated from the Middle East in 2025, creating a significant dependency on a region now facing severe supply disruptions.
Because HPAL projects are essential for producing nickel chemicals used in electric vehicle batteries, supply interruptions could ultimately affect downstream manufacturing sectors linked to the global energy transition. The situation demonstrates how geopolitical events can rapidly ripple through critical mineral supply chains that support future technologies.
Zinc and Lead Markets Under Increasing Pressure
The conflict is also affecting the zinc and lead industries through disruptions in freight and concentrate shipments. Iran has become an important supplier of zinc concentrate to China, accounting for more than 5% of Chinese zinc concentrate imports in 2025. Even partial interruptions to these flows have increased strain on an already tight concentrate market.
As supply conditions tighten, treatment charges in China have fallen into negative territory, highlighting the severity of the imbalance between concentrate availability and smelting demand. The pressure on zinc and lead markets underscores how regional disruptions can quickly influence pricing and availability across the broader metals sector.
Economic Slowdown Adds Another Layer of Risk
Beyond supply-chain disruptions, the conflict is beginning to weigh on the broader global economy. Industry analysts have revised global GDP growth forecasts downward, reducing expectations from 2.5% to 2.3% due to rising inflation, delayed interest-rate cuts, and a stronger U.S. dollar.
For metals markets, this creates a particularly difficult environment. Producers are simultaneously confronting higher input costs while facing the prospect of weaker industrial demand. This combination threatens profitability across multiple segments of the mining and metals industry.
Mining’s Risk Map Has Fundamentally Changed
One of the most important lessons emerging from the crisis is that the mining industry’s risk profile is no longer centered solely on mineral reserves or mining operations.
Today, vulnerability extends across sulphur supply chains, acid production, fuel availability, shipping routes, port infrastructure, and energy systems.
Mining companies with secure domestic supply networks and vertically integrated operations are likely to demonstrate greater resilience. In contrast, producers dependent on lengthy international shipping routes and concentrated sources of industrial feedstocks may face greater volatility and increasing operational risks.
The Energy Transition Faces a Critical Reality Check
The ongoing conflict has exposed a deeper structural weakness within the global energy-transition economy. Metals such as copper, nickel, zinc, and aluminium are often viewed as the foundation of a cleaner, more electrified future. Yet their production remains heavily dependent on traditional industrial systems built around fuel, shipping lanes, ports, sulphur supply, and politically sensitive trade corridors.
Even if hostilities ease in the near future, the effects on inventories, freight rates, supply chains, and industrial input costs are unlikely to disappear immediately.
The crisis serves as a powerful reminder that securing access to strategic minerals requires more than developing new mines. It also demands resilient logistics networks, diversified supply chains, and reliable access to the industrial inputs that make modern metal production possible. As the global mining industry navigates an increasingly complex geopolitical environment, one lesson is becoming clear: strategic metals are only as secure as the infrastructure and supply systems that support them.
