Metal prices and war have a long, intertwined history. When conflict breaks out, global supply chains shift, energy costs rise, and buyers scramble to secure stock before prices climb further. If you are sourcing steel, pipes, or non-ferrous metals for maritime, offshore, or industrial projects, understanding how metal prices respond to war is not just useful background knowledge — it is directly relevant to your procurement decisions.
The relationship between commodity prices and armed conflict is more nuanced than a simple “prices go up.” Some metals spike immediately. Others soften before rising later. And the factors driving those movements — supply disruptions, energy costs, shipping risk, and macroeconomic pressure — play out differently depending on the metal and the geography of the conflict. Here is what you need to know.
Do metal prices go up during war?
Yes, metal prices generally rise during wartime, but not all metals rise equally or at the same time. Wars create supply disruptions, increase energy costs, and introduce uncertainty into global markets — all of which tend to push prices upward. However, some metals are affected immediately, while others face indirect pressure that builds more slowly.
The most direct price increases occur when a conflict disrupts a major production or export region. A clear recent example is aluminium during the US–Israel conflict with Iran, where the effective closure of the Strait of Hormuz cut off a significant share of global supply. Gulf Cooperation Council countries produce around 6 million tonnes of primary aluminium per year, and the majority of that is exported through the Strait to Europe, Asia, and North America. When that route was disrupted, LME aluminium futures jumped sharply within weeks.
For steel, the picture is similarly complex. Wars increase demand for steel in military applications, infrastructure repair, and reconstruction, but they can simultaneously disrupt the iron ore, coking coal, and energy inputs needed to produce it. The net effect on steel prices during conflict depends heavily on where the fighting is, how long it lasts, and which trade routes are affected.
Which metals are most affected by wartime demand?
Aluminium, steel, copper, and nickel are the metals most sensitive to wartime conditions, though for different reasons. Aluminium faces the most immediate supply risk when conflicts hit major export corridors. Steel and copper respond to both demand surges and input-cost pressures. Nickel and other battery-linked metals face indirect effects through energy prices and chemical supply chains.
Aluminium
Aluminium stands out as the most directly exposed metal when conflicts affect the Middle East. The region accounts for roughly 9 percent of global supply, and disruptions to key smelters can quickly tighten the global market outside China. During the Iran conflict, missile strikes on major UAE and Bahraini plants damaged facilities representing around 4.6 percent of global capacity, with repair timelines stretching to up to a year. That kind of structural outage pushes the global ex-China aluminium market toward a deficit.
Steel and copper
Steel prices during conflict tend to rise due to a combination of increased demand and higher input costs, particularly energy. Copper is heavily influenced by macroeconomic sentiment — wars that threaten growth and delay interest-rate cuts can actually soften copper prices in the short term, even as physical supply risks build beneath the surface. The market initially prices conflict as an economic headwind before supply tightness becomes the dominant story.
Nickel and battery metals
Nickel faces a more indirect but significant risk through sulphur supply. Sulphur is a key input for sulphuric acid used in nickel processing via high-pressure acid leaching, and a large share of global sulphur supply has historically come from the Middle East. Disruptions to that supply raise production costs and can constrain output of battery-grade nickel intermediates over time.
Why do wars cause metal supply chains to break down?
Wars disrupt metal supply chains through four main channels: physical damage to production facilities, closure of key shipping routes, rising energy costs, and deteriorating investor and buyer sentiment. Each of these can act independently or compound the others, creating cascading effects across global markets.
Physical damage is the most dramatic trigger. When smelters, refineries, or mining operations are directly hit, production capacity disappears overnight. The damage to Emirates Global Aluminium’s Al Taweelah plant is a recent example — restoring full output requires up to a year of repairs, meaning that supply gap persists long after the initial attack.
Shipping route closures are equally powerful. The Strait of Hormuz is one of the world’s most critical chokepoints for commodity flows. When it becomes effectively closed or too risky to navigate, freight and insurance costs surge, and producers cannot get material to buyers even if the factories are still running. This drives up physical premiums in Europe, the US, and Asia well beyond the headline LME price movement.
Energy price increases are the third major mechanism. Aluminium smelting, steel production, and nickel processing are all highly energy-intensive. When oil and gas prices rise due to conflict, operating costs across the entire metals industry climb, compressing margins and, in some cases, forcing production cuts. This adds upward pressure to prices even for metals not directly linked to the conflict zone.
Finally, macroeconomic uncertainty weighs on demand expectations. Higher energy costs fuel inflation, which can delay interest-rate cuts and dampen industrial activity. This is why copper, zinc, and lead sometimes soften at the start of a conflict — markets price in weaker demand before physical supply tightness becomes the dominant factor.
How long do metal price increases last after a conflict begins?
Metal price increases driven by war can last anywhere from a few weeks to several years, depending on the severity of supply disruption and whether production capacity can be restored or replaced. Short-term spikes driven by panic buying and uncertainty often partially reverse. Structural supply losses — like damaged smelters or permanently rerouted shipping — sustain higher prices for much longer.
The pattern typically follows a recognisable sequence. Prices spike sharply at the outbreak of conflict as buyers and traders react to uncertainty. A partial correction often follows as initial panic subsides and markets assess the actual scale of disruption. Then, if the conflict persists or physical supply losses prove lasting, prices find a firmer floor and can trend higher again.
The Russia–Ukraine war in February 2022 is a useful reference point. LME aluminium prices reached their highest levels in years at that time, and the market took many months to fully absorb the implications for energy costs, raw material flows, and European industrial production. For steel buyers in particular, the commodity price volatility during wartime that followed in 2022 demonstrated how quickly market conditions can shift and how long the effects can persist.
The key variable is whether alternative supply can fill the gap. China’s role in aluminium is a prime example — if Chinese producers restart idle smelters, the global market can rebalance relatively quickly. But if the conflict damages infrastructure that takes a year or more to repair, and no alternative supply exists at scale, elevated prices become the new normal for an extended period.
How should metal buyers manage risk during geopolitical uncertainty?
Metal buyers can manage geopolitical risk by acting on a combination of forward planning, supplier relationships, and stock strategy. The buyers who navigate wartime price volatility best are those who take action before a crisis deepens, not after prices have already moved significantly.
Here are the key steps to consider when geopolitical tension is rising:
- Review your stock levels early. Waiting until prices have already spiked reduces your options. If you can see supply risk building, securing additional inventory at current prices is a straightforward hedge.
- Diversify your supplier base. Relying on a single source in or near a conflict zone concentrates your risk. Working with suppliers who hold broad stock across multiple locations gives you more flexibility.
- Understand your exposure by metal. Not all metals in your supply chain carry the same risk. Aluminium and energy-intensive metals tend to move first and fastest. Steel and copper may follow. Knowing which materials are most exposed helps you prioritise.
- Communicate proactively with your supplier. A good supplier will flag emerging risks before you ask. If you are not having those conversations, you may be missing early warning signals.
- Consider longer-term agreements where possible. Fixed-price or framework agreements with trusted suppliers can provide cost certainty during volatile periods, even if they require some flexibility on volume or timing.
The broader lesson from recent conflicts is that metal price increases during war are rarely short-lived surprises — they build from visible, traceable causes. Buyers who monitor supply chain news, maintain strong supplier relationships, and keep adequate stock are consistently better positioned than those who respond reactively.
