Why Copper Prices Fell 9% Amid Iran Conflict and Energy Surge

What happened

Copper prices fell to $12,081.74 per metric ton on the London Metal Exchange, down 9.4% since the US-Israel war with Iran started on February 28. The decline coincided with a broader market sell-off as energy prices surged—Dated Brent crude jumped from $70.94 per barrel on February 27 to $110.05 by March 24. At the same time, copper warehouse stocks surpassed one million metric tons for the first time since 2003, signaling abundant near-term supply. Strategists noted the price drop reflected both risk-off sentiment and concerns that higher energy costs could dampen global economic growth.

Why the stock moved

Copper-related stocks often move in tandem with the metal's price, which is closely tied to global economic health. The sharp rise in oil prices triggered worries about weaker growth and reduced industrial demand for copper, prompting investors to liquidate positions. BMO Capital Markets downgraded its near-term copper outlook, citing a disrupted macro setup and shifting preference toward aluminum and coal. The buildup in exchange inventories also signaled less scarcity, further pressuring sentiment. Copper stocks typically react negatively when demand fears outweigh supply concerns.

Bigger picture

Copper had been on a bull run through early 2026, hitting a record high of $13,524.24 per metric ton in January. That rally was partly driven by an arbitrage trade tied to potential US tariffs on refined copper that never materialized, drawing global supply to the US. Now the market faces competing forces: higher energy costs threaten demand, while the Iran conflict could disrupt sulfuric acid supply from the Middle East—a key input for about 16% of global copper production. If the war drags on, oxide copper operations may shut down due to acid shortages, potentially tightening supply. However, analysts warn that any price surge from supply cuts could be short-lived if an energy-driven recession dampens overall demand.

What investors watch

Investors should monitor the duration and intensity of the Iran conflict, especially its impact on sulfur trade through the Strait of Hormuz. Watch for updates on copper warehouse inventories and whether they continue to build or start drawing down. US trade policy shifts and central bank rate decisions will also matter, as a stronger dollar and delayed rate cuts can pressure industrial metal prices. Finally, keep an eye on demand indicators from major copper consumers like China, as well as any signals of supply disruptions at oxide copper operations reliant on sulfuric acid.
