Copper Futures Reversed Early Losses to Hit Multi-Week High. 5/28/26

Why It Matters

The tightening copper supply amid geopolitical tension and production revisions could push prices higher, affecting costs for industries from construction to clean‑energy technologies.

Key Takeaways

• July copper futures rebound, closing at multi‑week high since May 14.
• Codelco’s audit cuts 2025 output by 2%, sparking exec exits.
• Middle East conflict inflates copper smelting costs via sulfuric acid disruptions.
• China halts sulfuric acid exports, tightening global refining supply.
• Tight supply and strong demand pressure copper prices upward.

Summary

July copper futures erased early declines to finish at their highest level since May 14, after slipping to a four‑session low of $6.2420 per pound.

The rally saw prices climb to $6.4320, a 1.45% gain, leaving the contract up 1.32% at close. The bounce coincided with fresh supply‑side worries: Codelco’s internal audit revealed it had overstated 2025 output by 26,875 metric tons, trimming its forecast by roughly 2% and prompting senior departures and a criminal complaint.

Compounding the shortage, the ongoing Middle East conflict has disrupted sulfuric acid supplies—essential for copper refining—while China has suspended its own acid exports, forcing refiners to curtail capacity. These constraints arrive as global copper demand remains robust, driven by renewable‑energy projects and electric‑vehicle production.

Analysts see the confluence of tighter supply and resilient demand as a catalyst for further price appreciation, urging investors and manufacturers to monitor inventory levels and geopolitical risks closely.

Original Description

July Copper futures staged a significant intraday turnaround, reversing an early 1.55% drop to a session low of 6.2420 to close at their highest level since May 14, finishing the session up 1.32%. This price reversal comes amid tightening global supply dynamics. State-owned Codelco, the world's largest copper producer, revealed that an internal audit showed its 2025 output figures were overstated by 26,875 metric tons, leading to executive departures and a 2% downward revision to reported output. Additionally, global refining and smelting operations face compounding headwinds from geopolitical friction. The ongoing conflict in the Hormuz region has disrupted supply lines for sulfuric acid, a critical input for copper refiners. This issue is exacerbated by China suspending its sulfuric acid exports due to domestic shortages, forcing major refiners to cut capacity while global demand expectations remain elevated.
