Copper rises as tariff deadline nears

Copper markets strengthened on June 1, 2026 as traders positioned ahead of a key U.S. policy deadline that could affect refined copper trade. Prices rose in both New York and London, with London Metal Exchange copper quoted around $13,687.50 per ton and Comex front‑month copper near $6.45 per pound.

The move came as the U.S. Department of Commerce faces a June 30, 2026 deadline to deliver an updated copper market assessment and recommendation to President Donald Trump. Market participants view that recommendation as a potential trigger for import levies on copper.

The approaching deadline has become a central focus for refined copper traders, who are weighing possible changes to trade flows, import costs and regional price differentials depending on how the administration responds to the Commerce Department’s findings.

As traders attempted to get ahead of a possible tariff outcome, U.S. prices widened sharply relative to London. Comex copper traded at a more than $500 per ton premium to LME spot levels on June 1, highlighting heightened demand for metal priced on the U.S. exchange.

The elevated premium has supported renewed flows of copper into U.S. ports, as market participants sought to secure supply before any potential change in U.S. trade policy. These flows underline how expectations around the June 30 recommendation are already influencing physical market behavior.

Dealers and traders have been active in exploiting the spread between the two markets, reinforcing the divergence between U.S. and global benchmarks and underscoring the sensitivity of copper trade to prospective policy measures.

Major financial institutions are recalibrating their expectations in light of recent price action and policy risks. Goldman Sachs (GS) raised its London Metal Exchange end‑year copper price forecast to $13,735 per ton, compared with a prior forecast of $12,465 per ton.

The updated forecast reflects how analysts are incorporating both the current strength in copper prices and the potential impact of policy developments on market balances. While price projections differ across the market, such revisions are closely watched by traders and corporate buyers.

The combination of higher spot prices, wider U.S. premiums and revised institutional forecasts has reinforced the perception of a tighter and more policy‑sensitive copper market heading into the second half of 2026.

Policy changes outside the United States are also drawing attention. China’s State Council has announced new outbound investment rules that will take effect on July 1, 2026, adding a separate policy factor for copper‑related capital and supply‑chain decisions.

These rules are seen as relevant for cross‑border capital flows and investment strategies tied to industrial commodities, including copper. Companies with exposure to Chinese financing or overseas copper assets are monitoring how the rules may shape future investment patterns.

Together with the looming U.S. recommendation on copper trade, the Chinese measures highlight how government policy across major economies is increasingly intertwined with pricing, trade and investment decisions in the copper market.
