Copper Surges to Record Highs Despite Sluggish Manufacturing Demand

Copper markets are experiencing an unprecedented rally in 2026, with the benchmark Comex copper price averaging a historic $6.59 per pound in August. Industry analysts note that despite mounting warehouse inventories reaching levels not seen since 2003, prices continue to climb driven by speculative trading, artificial intelligence data center builds, green energy demand, and anticipation of U.S. trade tariffs. Conversely, physical consumption paints a more subdued picture, with U.S. construction spending and manufacturing activity contracting significantly from prior peaks, highlighting a disconnect between financial markets and physical demand.

Analyzing the 2026 Copper Rally and Inventory Surges

In his September report, New York-based industry analyst John W. Gross highlighted that copper has posted seven consecutive monthly high averages since March of last year, far surpassing historical peaks from 2011 and 2022. Global exchange inventories tracked by the International Copper Study Group (ICSG) reached nearly 965,000 metric tons by the end of July, the highest level recorded since August 2003. This inventory accumulation has been heavily concentrated in U.S. Comex warehouses due to preemptive positioning ahead of potential trade policy shifts and tariffs, whereas Shanghai Futures Exchange inventories have actually declined.

Divergence Between Financial Speculation and Physical End-Use

While energy transition vectors such as EV, renewable installations, and massive AI data center buildouts provide a compelling structural backdrop, actual physical consumption tells a different story. In the United States—the world’s largest economy—housing starts, building permits, and overall construction spending have trended lower, peaking in early 2025 and subsequently sliding. Furthermore, U.S. manufacturing spending fell to $170 billion in July, marking a 32 percent drop from its annualized high. Veteran market observers point out that this stark divergence indicates speculative capital participation is amplifying price volatility well beyond what traditional supply-demand fundamentals dictate.

SuperMetalPrice Commentary:

The widening gap between ballooning exchange inventories and record-high copper prices signals extreme speculative influence. While green energy and data centers provide long-term fundamental backing, near-term industrial contraction suggests caution for buyers chasing this rally.
