What copper’s jump to all-time highs tells us

Copper prices reached an all-time high on Thursday, but this surge is complicated by a more fluctuating economic growth context, making the metal, known as "Dr. Copper," a less reliable indicator of economic health. The U.S. copper futures hit around $6.90 per pound, peaking before returning to their original value. This price increase appears to be a result of a mix of factors, including restricted supply, significant grid investments, uncertainties around U.S. tariffs, and increased demand for electrification.

Traditionally, copper has been regarded as a barometer of global economic activity. However, the current price spike is attributed to data center and power grid demand driven by the rapid expansion of the AI industry. William Osnato, Barchart's director of commodity data research and analysis, explained that this demand surge is more intense and differs from the regular economic growth that typically supports copper prices.

Furthermore, copper's price rise is also linked to its limited supply. The process of mining copper is costly, and establishing new mines can take up to 10 years, which contributes to the tight supply of this metal. Michael Widmer, Bank of America's head of metals research, emphasized that the price movement is not primarily driven by copper demand but rather by supply constraints.

He noted that there is a lack of new mine supply and disruptions in mine operations have added to these limitations. Mine growth has been sluggish, and disruptions in Chile, the world's largest single copper producer, have worsened the situation. Severe weather conditions such as heavy snow, rainfall, and high winds have also disrupted mining activities in the region.

In addition, potential U.S. Section 232 tariffs and China's crackdown on scrap copper availability have further tightened global copper supplies in 2026. In June, President Donald Trump imposed 50% tariffs on imports of semi-finished copper products and copper-intensive derivative products. Meanwhile, China's demand for copper has remained robust and is closely associated with increased electrification, rather than an economic boom.

China's power grid investment has seen a 13% increase year over year in the first half of this year, and the country has recently announced a plan to invest approximately $574 billion in power grid upgrades. This development came after the Democratic Republic of Congo officially banned copper and cobalt concentrates exports to promote domestic processing.

Osnato highlighted that the supply disruptions have led consumers to withdraw metal from London Metal Exchange warehouses, thereby driving up refining costs. He emphasized that this situation is indeed unusual for "Dr. Copper."
