Copper prices spiked to historic highs after Donald Trump’s dramatic tariff threat upended global metals markets and sparked a rush to secure supply.
Comment on 50% Tariffs Sparks Record Copper Rally
Copper markets saw a wild, historic session after former President Donald Trump declared he would impose a 50% tariff on industrial metals. The most-traded US copper futures exploded higher from roughly $5 per pound to an intraday record of $5.9530, marking a stunning 20% gain in just hours.
Though prices later settled back to around $5.5055 per pound, the move underscored the intense volatility unleashed by the tariff announcement.
Copper Chart Daily – The Support Held
Traders reacted instantly to the White House threat by rushing to lock in metal supplies before any new duties take effect. Shipping records have already been showing a surge in copper inflows to the US in recent months as merchants sought to front-run anticipated tariffs, and Trump’s comments intensified the scramble.
Tight Supply, Inventory Drain, and Backwardation
The copper market was already primed for an upward move. In the final week of June, prices had pushed to a three-month high on the London Metal Exchange (LME) thanks to tighter supply conditions and improved risk sentiment amid hopes for easing tensions between the US and China. The 20-day Simple Moving Average (SMA) on daily charts had been providing solid technical support, reinforcing the bullish trend.
But Trump’s tariff threat sent the market into overdrive. Inventories on the LME and in China rapidly drained as traders rerouted record volumes of metal to the US. This surge in demand drove the market into steep backwardation, a structure where near-term prices trade at sharp premiums to longer-dated contracts—a classic sign of acute supply stress.
New York Contracts Blow Out vs. London
In the wake of Trump’s comments, New York copper contracts recorded their biggest one-day rise ever, at one point trading at a 25% premium to comparable London futures. Such an unprecedented spread signals not just speculative enthusiasm but a genuine logistical rush to move metal into US warehouses before the tariffs bite.
Market participants now face the prospect of even higher short-term prices as exporters and merchants compete to deliver copper ahead of the tariff implementation date. The surge in Comex prices will almost certainly incentivize even more shipments to the US, likely keeping spot premiums elevated in the near term.
Outlook: Short-Term Gains but Policy Uncertainty Looms
While today’s spike showcases the market’s extreme sensitivity to trade policy, it also raises serious questions about sustainability. Many analysts warn that if Trump’s tariffs are enacted as threatened, they could disrupt established supply chains, raise costs for US manufacturers, and trigger retaliatory measures from key trading partners.
For now, traders are bracing for continued volatility as they try to anticipate both the timing and scope of any new duties. With inventories tight and shipping logistics already strained, the copper market looks set to remain highly reactive to every new policy headline, leaving prices vulnerable to more dramatic swings in the weeks ahead.
