Escalating Red Sea disruption threatens aluminium output (up to 3.5 million tonnes lost), Indonesian nickel processing, and zinc flows -- separate chokepoints in one conflict.
At a glance
- Rerouting shipments around Africa's Cape of Good Hope to avoid the Red Sea adds 10-14 days to transit times and raises shipping costs by 20-50%, a direct tax on every metal that moves through the region.
- Wood Mackenzie estimates the Middle East is on track to lose up to 3.5 million tonnes of aluminium production in 2026 -- about 3% of global supply -- with EGA Al Taweelah (UAE) and ALBA (Bahrain) among the smelters hit by power-plant damage and emergency shutdowns.
- Indonesian nickel processors sourced more than 75% of the sulphur used in their HPAL (high-pressure acid leach) refining process from the Middle East in 2025, leaving that supply chain exposed to the same disruption even though nickel isn't mined anywhere near the Red Sea.
- Iranian zinc concentrate shipments to China, which made up over 5% of China's 2025 zinc concentrate imports, have also been disrupted -- a separate, smaller chokepoint riding on the same conflict.
What happened
The renewed escalation around the Red Sea this week -- Saudi Arabia shutting a key oil pipeline after drone attacks and Iran-aligned Houthi forces tightening their grip on shipping lanes -- has reopened a supply-chain risk that has been building since the Middle East conflict began in February 2026: metals and mining supply routes that run through the region. Ships avoiding the Red Sea have to reroute around Africa's Cape of Good Hope, adding 10 to 14 days to transit times and pushing shipping costs up 20% to 50%. Wood Mackenzie estimates the region is on track to lose up to 3.5 million tonnes of aluminium production in 2026 -- roughly 3% of global supply -- after power-plant damage and emergency shutdowns hit major smelters including EGA Al Taweelah in the UAE and ALBA in Bahrain. The disruption reaches well beyond aluminium: Indonesian nickel processors that get more than 75% of the sulphur they need for HPAL refining from the Middle East are drawing down inventories, and Iranian zinc concentrate exports to China -- more than 5% of China's 2025 imports -- have also been interrupted.
The details
What makes this disruption worth tracking metal by metal, rather than as one generic "Middle East risk" headline, is that it doesn't hit every commodity through the same channel. Aluminium is losing actual production capacity -- smelters in the UAE and Bahrain have taken direct hits to their power supply, which is a physical constraint no amount of rerouted shipping fixes. Nickel and copper, by contrast, aren't primarily losing output; they're losing access to an input, sulphur and sulphuric acid, that happens to move through the same conflict zone on its way to refineries thousands of kilometres away in Indonesia and the Democratic Republic of Congo.
That distinction matters for how long each disruption is likely to last and how it resolves. Aluminium smelting capacity taken offline by power-plant damage comes back only when the plant is repaired or replaced -- a slow, capital-intensive process, which is why Wood Mackenzie's 3.5-million-tonne 2026 loss estimate reads as a hard ceiling on regional output rather than a temporary dip. The nickel and copper acid-supply squeeze is a different kind of problem: it's a logistics and pricing issue, not a production one, which is why sulphuric acid prices spiking to $1,000-1,400 a tonne for DRC copper producers is the more useful number to watch than any nickel or copper production figure -- the metal is still there, it's just getting more expensive to process.
The shipping-cost mechanism sits underneath almost all of it. Every cargo that would normally transit the Red Sea and Suez Canal now either pays a war-risk premium to keep using that route or adds 10 to 14 days sailing around the Cape of Good Hope, at a 20-50% cost increase either way. That's not a cost any single metal absorbs differently -- it's a flat tax on regional trade that compounds whatever is happening on the production side. For aluminium already losing output, added shipping costs on top of scarcer supply is a double hit. For copper, where the direct production impact has stayed under 1% of global supply, the same shipping tax is a smaller but still real drag.
Zinc's exposure looks narrower on paper -- Iranian concentrate flows to China represented just over 5% of China's 2025 imports -- but a single-digit percentage of a country's largest zinc buyer's supply is still enough to move regional pricing if it stays disrupted, especially layered onto whatever else is already squeezing that market. None of these are catastrophic numbers in isolation. Together, across five different metals moving through the same set of shipping lanes and power grids, they describe a region that has become a genuine single point of failure for parts of the global metals supply chain -- not because any one metal depends entirely on it, but because so many different metals each depend on it a little.
Why it matters
Most metal-price stories trace back to a single mine, a single tariff, or a single central bank decision. This one is different: it's a reminder that shipping lanes and regional power grids can quietly become a shared vulnerability across metals that have nothing else in common, from aluminium smelted in the Gulf to nickel processed in Indonesia to copper refined in the Congo. For Indian manufacturers and traders sourcing any of these metals internationally, a disruption this spread out across the supply chain is harder to hedge against than a single-commodity shock, because it doesn't show up as one clean price move -- it shows up as a slow accumulation of higher shipping costs and acid prices across several unrelated metals at once.
Our read
Outlook: bullish. Confirmed physical production losses in Gulf aluminium and rising input costs for nickel and copper refiners both point toward tighter supply and higher costs, though the impact is uneven across metals -- aluminium and the acid-dependent processors face a clearer bullish case than copper's own direct, comparatively limited exposure.
What to watch
- Sulphuric acid prices for DRC copper refiners and sulphur prices for Indonesian HPAL nickel processors, as the clearest real-time gauge of how the Gulf disruption is spreading beyond aluminium
- Any further escalation around Red Sea shipping lanes or Gulf power infrastructure that could widen the 3.5-million-tonne aluminium production loss already estimated for 2026
- Container and bulk shipping rates for the Cape of Good Hope reroute as an indicator of how much of the 20-50% cost increase is persisting versus easing

Detailed analysis
Timeline
- 2026-02-01: The current Middle East conflict began, setting off a chain of disruptions to regional power infrastructure and shipping routes.
- 2026-05-27: Wood Mackenzie published its estimate that the Middle East is on track to lose up to 3.5 million tonnes of aluminium production in 2026, alongside disruptions to copper, nickel and zinc supply chains.
- 2026-09-15: Saudi Arabia shut a key oil pipeline after drone attacks and Houthi forces tightened control of Red Sea shipping lanes, renewing pressure on the same metals supply chains.
Supply Drivers
Power-plant damage and emergency shutdowns at Gulf aluminium smelters including EGA Al Taweelah (UAE) and ALBA (Bahrain) are on track to cut up to 3.5 million tonnes from 2026 regional aluminium output, a hard production loss rather than a temporary shipping delay.
Inventory Drivers
Indonesian nickel processors are drawing down sulphur inventories after more than 75% of their 2025 HPAL-grade sulphur imports originated from the Middle East, a supply chain now exposed to the same regional disruption even though nickel processing itself happens far from the conflict.
Geopolitical Risks
Saudi Arabia's shutdown of a key oil pipeline after drone attacks and Iran-aligned Houthi forces tightening control of Red Sea shipping lanes this week are the latest escalation of a Middle East conflict running since February 2026, forcing metals cargoes to either pay war-risk premiums through the Red Sea or reroute around Africa's Cape of Good Hope at a 20-50% cost increase.
Refinery Output
DRC copper producers depend on the Gulf for more than 90% of their sulphuric acid supply, used in copper refining; acid prices have surged to $1,000-1,400 a tonne as that supply chain has been disrupted by the conflict.
What could lift prices
- A confirmed 3.5-million-tonne aluminium production loss and sharply higher input costs for copper and nickel refiners both point toward tighter physical supply and higher costs across several metals simultaneously.
What could weigh on prices
- Copper's direct exposure has stayed limited -- Wood Mackenzie put the combined loss of Iranian output and Gulf semis exports at under 1% of global supply -- suggesting not every metal in this supply chain faces a comparable hit.
- A resolution or de-escalation of Red Sea shipping risk could unwind the cost pressure relatively quickly for metals facing a logistics squeeze rather than a physical production loss.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United Arab Emirates | High | EGA's Al Taweelah aluminium smelter is among the Gulf facilities that have lost significant production capacity from power-plant damage and emergency shutdowns tied to the conflict. |
| Indonesia | Medium | Indonesian HPAL nickel processors sourced more than 75% of their sulphur imports from the Middle East in 2025, leaving their processing operations exposed to a disruption thousands of kilometres from the actual conflict. |
| Democratic Republic of Congo | Medium | DRC's copper belt depends on the Gulf for more than 90% of its sulphuric acid supply, a critical input for copper refining now facing sharply higher prices. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Metal Smelting | Negative | Gulf aluminium smelters have lost production capacity to power-plant damage, while copper and nickel refiners elsewhere face sharply higher input costs for Middle East-sourced sulphur and sulphuric acid. |
| Shipping | Negative | Vessels rerouting around Africa's Cape of Good Hope to avoid the Red Sea face 10-14 additional transit days and 20-50% higher shipping costs, a direct operational cost increase for carriers and their metals-industry customers. |
Who gains, who loses
- Non-Gulf aluminium producers: Aluminium smelters outside the Middle East stand to benefit from tighter regional supply and higher prices as up to 3.5 million tonnes of Gulf production capacity is lost in 2026.
- Indonesian nickel processors and DRC copper refiners: Both depend heavily on Middle East-sourced sulphur and sulphuric acid for processing, and both face sharply higher input costs as that supply chain is disrupted by a conflict thousands of kilometres from their own operations.
Other ways this could play out
- If Red Sea shipping risk eases, the logistics-driven cost pressure on nickel and copper refiners could unwind relatively quickly, even though aluminium's physical production losses would take longer to recover as damaged Gulf facilities are repaired.
- If the conflict escalates further, additional Gulf production capacity or shipping lanes could come under threat, extending the current disruption beyond the metals already affected.
Price risks
- Further Gulf power infrastructure damage could push aluminium's 2026 production loss beyond the current 3.5-million-tonne estimate, tightening global supply further.
- A prolonged sulphur and sulphuric acid supply squeeze could keep raising processing costs for Indonesian nickel and DRC copper operations even without any change in the underlying metal's mined supply.
Historical comparison
- 2023-2025: Earlier Red Sea attacks on commercial vessels during this period already forced mineral shipments to begin rerouting around the Cape of Good Hope, a pattern the current 2026 conflict has extended and deepened.
