Copper Hits Record $14,617 a Ton Amid Tariff Speculation and Supply Constraints

Copper surged to an all‑time high of $14,617 a ton on the London Metal Exchange, extending a rally into a fourth trading session. The price rise follows a 17% gain for the metal so far this year, underpinned by tight near‑term supply and steady industrial demand.

Tariff Expectations Influence Pricing

Traders are positioning for a possible U.S. tariff on refined copper products. A proclamation signed last August set a 50% tariff on semi‑finished copper, while refined metal was exempt. The Commerce Department was instructed to revisit the issue, with a report originally due June 30 that remains unpublished. Despite the lack of a final decision, market participants continue to price the potential levy, prompting merchants to ship hundreds of thousands of tons to the United States to capture higher prices.

Supply Fundamentals Remain Tight

Analysts note that the world’s largest copper mines are aging, and new output is not keeping pace with demand from data centers, renewable energy projects, and grid upgrades. Morgan Stanley highlighted the possibility of the first annual decline in global copper mine supply since 2017. Market analyst Jim Bianco reported that copper has risen more than 68% since April 2025, a move that began before tariff speculation intensified.

Gold’s Relative Performance

While copper climbs, gold has retreated, trading near $4,405 an ounce—about 21.8% below its record high of $5,589.38 set on January 28. Some traders view the divergence as a rotation from defensive assets into industrial exposure. The copper‑gold ratio recently broke its downtrend, though the signal remains mixed as gold has risen roughly 10% in August and is up about 25% over the past 12 months.

Outlook

The pending U.S. tariff decision remains the key near‑term variable. Its outcome will help determine whether copper’s record price is primarily driven by policy expectations or by an underlying supply gap.
