Copper Prices Drop 9% as Iran War Fuels Economic Growth Concerns

What happened

London Metal Exchange copper prices fell 9.4% to $12,081.74 per metric ton between late February and late March 2026 as the US-Israel war with Iran escalated. The conflict pushed Dated Brent crude oil from $70.94/barrel on February 27 to over $110/barrel by late March, fueling inflation concerns and triggering a risk-off move across industrial metals. At the same time, global copper inventories surged past 1 million metric tons for the first time since 2003, signaling increased availability after a period of tightness. The combination of rising energy costs, concerns over economic growth, and swelling stockpiles drove investors to liquidate long positions in copper. Central banks unwound rate-cut expectations, and the U.S. dollar strengthened, adding further pressure on base metals prices. Industry analysts noted that the Iran conflict disrupted what had been a constructive macroeconomic setup for 2026, prompting some strategists to downgrade their near-term copper outlook. The Middle East accounts for nearly half of global sulfur trade, much of it transiting the Strait of Hormuz. Sulfur is critical for producing sulfuric acid, a key input in solvent extraction/electrowinning copper production, which represents about 16% of global output. Industry observers warned that if the conflict persists beyond three weeks, copper oxide operations could face shutdowns due to acid shortages.

Why it matters

For Freeport-McMoRan, a major global copper producer, this sector-wide price decline directly affects revenue and profitability. Copper's status as a bellwether for economic health means that price swings driven by geopolitical events can significantly impact mining companies' earnings and investment plans. The dual forces at play—demand fears from energy-driven inflation and potential supply disruptions from sulfuric acid shortages—create uncertainty for production planning and capital allocation. Freeport-McMoRan's operations rely on stable input costs and predictable demand, so prolonged conflict-related volatility complicates near-term forecasts. The company must navigate between the risk of weaker demand if high energy prices trigger a recession and the possibility of supply bottlenecks that could tighten the market. Additionally, the surge in exchange inventories signals a shift from the tight supply conditions that supported higher prices earlier in 2026. This dynamic may pressure margins and influence hedging strategies. Freeport-McMoRan's exposure to large-scale copper production means sector-wide price movements have outsized effects on its financial performance and strategic decisions.

Bigger picture

The copper market in early 2026 had been buoyed by expectations of strong demand from AI infrastructure buildouts, electrification, and renewable energy projects. Data centers supporting AI can consume up to 50,000 metric tons of copper each, far exceeding traditional facilities. Long-term demand projections by S&P Global forecast a 10 million metric ton supply deficit by 2040, driven by electrification and technological expansion. However, the Iran war has introduced near-term volatility that overshadows these structural tailwinds. The conflict's impact on energy prices and supply chains reminds investors that geopolitical risks can temporarily derail even the most compelling demand narratives. Meanwhile, new U.S. production capacity is coming online. Taseko Mines' Florence project in Arizona began producing refined copper in March 2026 using in-situ recovery methods, targeting 85 million pounds annually. This represents a shift toward unconventional extraction techniques to tap abundant low-grade ores without relying on traditional smelters. The broader mining sector is watching how quickly these innovative projects can scale, especially given that new copper mines typically take 18 years to move from discovery to production, while AI data centers reach operation in under two years. This timeline mismatch underscores the supply challenges facing the industry, even as near-term prices remain pressured by macroeconomic and geopolitical headwinds.

What to watch

Key developments to monitor include the duration and resolution of the Iran conflict, which will determine whether energy prices remain elevated and whether sulfuric acid supply chains face prolonged disruptions. If the war extends beyond a few weeks, watch for announcements from copper oxide producers about potential shutdowns due to acid shortages. Central bank policy responses to inflation will also shape copper demand; any pivot back toward rate cuts could support economic growth and metal consumption. Investors should track global copper inventory levels, particularly on the London Metal Exchange, to gauge whether the recent stockpile buildup continues or reverses. Updates on AI infrastructure buildouts and electrification projects will signal whether long-term demand drivers remain intact despite near-term volatility. Finally, progress at new U.S. projects like Florence will indicate whether innovative extraction methods can help close the gap between supply and demand. Freeport-McMoRan's quarterly earnings and production guidance will provide insights into how the company is managing margin pressures and adjusting to shifting market conditions.
